DETAILED DESCRIPTION

(19) The inventive subject matter provides apparatus, systems, and methods to aid in the disassembly, maintenance, and cleaning of firearm components, preferably related to the extractor and extractor pin of AR-15 and M-16 rifle bolt assemblies. Tools of the inventive subject matter are sized and dimensioned to fit firearm bolt assemblies of various calibers, and are preferably particularly sized and dimensioned for use with .223 or .308 imperial caliber firearms, or 5.56 metric caliber firearms.

(20) It should be appreciated that firearms are typically made of rugged, resilient material, capable of withstanding a variety of environmental and physical stresses and maintaining operational capability. It is contemplated that tools and apparatus of the inventive subject matter are composed of similar or the same materials as firearm components, including for example steel, aluminum, titanium, iron, nickel, various metallic alloys, and other resilient materials. Tools composed of such materials advantageously have resilient properties similar to the firearm components, including favorably tolerating environmental and physical wear and tear associated with field use.

(21) However, it should also be appreciated that contemplated tools may be made of lighter, cheaper materials that are less resilient than metals and alloys but none the less provide favorable characteristics. For example, tools and apparatus composed of hard and soft plastics, hard and soft rubbers, and other polymers, as well as ceramics or other crystalline materials may be lighter and to carry and provide simpler manufacturing processes. Preferred embodiments include tools and tool components comprised at least partial of polymer material, including at least 50%, 60%, or 70% of tools and tool components (by mass, weight, or volume) comprising at least one polymer material, while especially preferred embodiments comprise at least 80%, 90%, 95%, or 98% of tools and tool components (by mass, weight, or volume) comprise at least one polymer material.

(22) Tools of the inventive subject matter can further be comprised partially, mostly, or entirely of a polymer material, but more preferably are composed of various polymer materials, including different tool components comprised of different compositions of polymer materials. For example, it is contemplated that tool components that are subject to low stress (e.g., forces less than 10N, 5N, 3N, 2N, or 1N) during use can be composed of weaker, cheaper polymer or polymer blends, while tool components that are subject to moderate or high stresses (e.g. greater than 10N, 15N, 20N, or 25N) can be composed of stronger polymer or polymer blends, and can further include additional metallic bracing. For example, a push rod subject to high stress can be composed of steel, while the push rod is fitted with a polymer handle for user comfort and ease of use.

(23) FIG. 1 depicts inserting rod 110 and removal rod 120. Inserting rod 110 comprises handle 112, inserting shoulder 114, and inserting stem 116. Inserting shoulder 114 defines a change in dimension between handle 112 and inserting stem 116.

(24) As depicted, both handle 112 and inserting stem 116 have cylindrical structures sharing the same longitudinal axis but having different radius and circumference, to with handle 112 has a larger radius and circumference than inserting stem 116. Further, the circumference and radius of inserting stem 116 is not more than the circumference and radius of applicator channel 420 of tool block 400 in FIG. 4, such that inserting stem 116 can be inserted into applicator channel 420. It is contemplated that the circumference and radius of applicator channel 420 and inserting stem 116 will be the same, or at least within a tolerance of 0.001%, 0.01%, 0.1%, 0.5%, 0.8%, 1%, 2%, or 5% of each other. Inserting shoulder 114 is sized and dimensioned such that, as inserting rod 110 is inserted into applicator channel 420, inserting shoulder 114 comes to rest against the portion of housing 410 adjacent to applicator channel 420 and prevents further insertion of inserting rod 110 into applicator channel 420. Inserting stem 116 has a length defined as the dimension along inserting stem 116 between inserting shoulder 114 and the end of inserting stem 116. In preferred embodiments, the length of inserting stem 116 is at least the length from the opening of applicator channel 420 on the exterior of housing 410 to an intersection between applicator channel 420 and receiving channel 480.

The relation between the size, shape, and dimensions of removal handle 122, removal shoulder 124, and removal stem 126 are similar to that of handle 112, inserting shoulder 114, and inserting stem 116. The circumference and radius of removal stem 126 is not more than the circumference and radius of applicator channel 420. It is contemplated that the circumference and radius of applicator channel 420 and removal stem 126 will be the same, or at least within a tolerance of 0.001%, 0.01%, 0.1%, 0.5%, 0.8%, 1%, 2%, or 5% of each other. Removal stem 126 can be inserted into applicator channel 420. Further, the circumference and radius of removal stem 126 is not more than the circumference and radius of extractor pin hole 224 of bolt 220 in FIG. 2. It is contemplated that the circumference and radius of extractor pin hole 224 and removal stem 126 will be the same, or at least within a tolerance of 0.001%, 0.01%, 0.1%, 0.5%, 0.8%, 1%, 2%, or 5% or each other. Removal stem 126 can be inserted into extractor pin hole 224. Viewed from another perspective, the circumference and radius of removal stem 126 is not more than the circumference and radius of extractor pin 222 of bolt 220 in FIG. 2. Removal stem 126 has a length defined as the dimension along removal stem 126 between removal shoulder 124 and the end of removal stem 126. In preferred embodiments, the length of removal stem 126 is at least the combined length of applicator channel 420 and extractor pin hole 224 of bolt 220 in FIG. 2. Viewed from another perspective, the length of removal stem 126 is equal to at least the sum of the length of applicator channel 420 and the length of extractor pin 222 of bolt 220 in FIG. 2.

(26) It is contemplated that handles 112 and 122, as well as inserting stem 116 and removal stem 126, are composed of the same material (e.g., hard plastic, polymer, polymer blend, composite material, metallic or alloy, natural or processed woods, etc.). In preferred embodiments, handles 112 and 122 are composed of polymer or polymer blends suitable for efficient plastic manufacturing processes (e.g., blow molding, casting, compression molding, extrusion, fabrication, foaming, injection molding, rotational molding, etc.). In such embodiments, stems 116 and 126 can be comprised of the same polymer or polymer blends as handles 112 and 122, allowing for efficient manufacturing of the inserting rod 110 and removal rod 120. In especially preferred embodiments, stems 116 and 126 are composed of metal or a metal alloy (preferably steel), while handles 112 and 122 are composed of plastic.

(27) FIG. 2 depicts locking rod 210 and bolt 220. Locking rod 210 comprises handle 212, locking shoulder 214, locking stem 216, and tapered portion 218. Locking stem 216 has a cylindrical structure sharing the same longitudinal axis as handle 212. Handle 212 has larger cross sectional dimensions than locking stem 216. The circumference and radius of locking stem 216 is not more than the circumference and radius of locking channel 430 of tool block 400 in FIG. 4, such that locking stem 216 can be inserted into locking channel 420. It is contemplated that the circumference and radius of locking channel 430 and locking stem 216 will be the same, or at least within a tolerance of 0.001%, 0.01%, 0.1%, 0.5%, 0.8%, 1%, 2%, or 5% of each other. Locking shoulder 214 is sized and dimensioned such that, as locking rod 210 is inserted into locking channel 430, locking shoulder 214 comes to rest against the portion of housing 410 adjacent to locking channel 430 and prevents further insertion of locking rod 210 into locking channel 420. Locking stem 216 has a length defined as the dimension along locking stem 216 between locking shoulder 214 and the end of locking stem 216. In some embodiments, the length of locking stem 216 is at least the length from the opening of locking channel 430 on the exterior of housing 410 to an intersection between locking channel 430 and receiving channel 480. In preferred embodiments, the length of locking stem 216 is not more than the combined length of locking channel 430 and tapered hole 228 of bolt 220.

(28) As previously described, locking rod 210 can be composed of materials selected for simple manufacturing processes or low cost (e.g., plastics, polymers, polymer blend, composite material, natural or processed woods, etc.) or can be selected for high resilience or life of use (e.g., high density plastics, metals, metal alloys, etc). In preferred embodiments, locking rod 210 is composed of polymers or polymer blends and can be hollow to reduce cost of material for manufacture.

(29) Bolt 220 comprises bolt body 222, extractor pin 224, extractor pin hole 226, extractor 228, and tapered hole 229. Extractor 228 is coupled to bolt body 222 by extractor pin 224. The removal of extractor pin 224 from extractor pin hole 226 decouples extractor 228 from bolt body 222. Such decoupling permits extractor 228 to be removed from bolt 220, enabling the cleaning, maintenance, repair, and modification of extractor 228 and the portions of the bolt body that interface with extractor 228. Tapered hole 229 configured as a through hole. The opening of tapered hole 229 depicted in FIG. 2 has a larger dimension then the opening of tapered hole 229 on the reverse side of bolt 220, not depicted.

(30) While bolt 220 is representative of a bolt for an AR-15 or M-16 rifle, it should be appreciated that such rifles are available in various calibers (imperial or metric) having bolts of different sizes and dimensions. It is contemplated that various tools and methods of the inventive subject matter are sized and dimensioned for use with bolts for various caliber rifles (e.g., .17, .22, .223, and .30 imperial caliber, or 5.56, 6.5, 7.62 metric caliber), and preferably sized and dimensioned for use with .223 or .308 imperial caliber or 5.56 or 7.62 metric caliber. It is also contemplated that tools sized and dimensioned for use with larger caliber bolts (e.g. .308 imperial caliber or 7.62 metric caliber) may be fitted with adapters (e.g., tube, hollow cylinder, spacers, etc) such that the larger caliber tool can be used properly with smaller caliber bolts. Viewed from another perspective, it is contemplated that tools suited for .308 imperial caliber bolts can be fitted with adapters so that the tool can be used with .223 imperial caliber bolts.

(31) FIG. 3 depicts lock and bolt assembly 300, comprising locking rod 210 and bolt 220 joined at intersection 310. As discussed above, bolt 220 comprises tapered hole 222, which further comprises tapered hole openings 222a and 222b as depicted in FIG. 3. Tapered hole opening 222a has a circumferential dimension that is larger than tapered hole opening 222b. Further, locking stem 216 and tapered portion 212 are sized and dimensioned to correspond with the dimensions of tapered hole openings 222a and 222b such that tapered portion 212 can be inserted into and through tapered hole opening 222a, but cannot be inserted into and through tapered hole opening 222b. Viewed from another perspective, tapered hole 222, tapered hole openings 222a and 222b, locking stem 216, and tapered portion 212 are sized and dimensioned such that locking rod 210 can only be inserted into bolt 220 through tapered hole opening 222a. Further, a length along locking stem 216 is defined between locking shoulder 214 and intersection 310. This length is roughly (e.g. within 5%, within 10%, or within 20%) the length of locking channel 430.

(32) FIGS. 9A and 9B depict bolt section 900A viewed from a side perspective and along sight line 910, respectively. Tapered hole openings 222a and 222b have the dimensions as described above. Further illustrated is axis 1, which corresponds with a longitudinal axis of tapered hole 222. Also illustrated is axis 2, which corresponds with a longitudinal axis of extractor pin hole 226 having extractor pin hole openings 226a and 226b. As seen in the longitudinal perspective view in FIG. 9b, the projection of axis 2 on axis 1 forms angle . It is generally expected that angle will be greater than 10, 15, 20, 25, or 30, and in preferred embodiments will be 22.5.

(33) FIG. 4 depicts top plan view of tool block 400 comprising housing 410, applicator channel 420, locking channel 430, inserting rod cavity 440, and removal rod cavity 450. Inserting rod cavity 440 and removal rod cavity 450 are sized and dimensioned to receive and releasably secure inserting rod 110 and removing rod 120, respectively. Applicator channel 420 and locking channel 430 are oriented such that each channel intersects receiving channel 480 (see FIG. 5). Further, a projection along the longitudinal axis of receiving channel 480 of the longitudinal axis of applicator channel 420 and locking channel 430 produces an angle of from FIG. 9B between the axes. Viewed from another perspective, a projection of the applicator channel 420 axis and the locking channel 430 axis forms the angle from FIG. 9B between the two axes.

(34) It is contemplated that tool block 400 can be made of various materials already described. In embodiments well suited for field use, tools of the inventive subject matter can be made of high resilience plastics that are light weight. For tools suited for use in homes, workshops, or gunsmithing, the tools can be made of higher quality materials, such as machined aluminum, and have similar finish and feel as the material the firearm is composed of.

(35) FIG. 5 depicts a bottom, back side perspective view of tool block 400 comprising housing 410 and further comprising receiving channel 480 and removal channel 470. Removal channel 470 is oriented such that is aligns and shares a longitudinal axis with applicator channel 420 (not pictured). Further, removal channel 470 intersects receiving channel 480. In some embodiments, the circumference and radius of removal channel 470 is at least the circumference and radius of applicator channel 420. Viewed from another perspective, the circumference and radius of removal channel 470 is at least the circumference and radius of extractor pin 222 and extractor pin hole 224.

(36) FIG. 6 depicts a top, right side perspective view of tool assembly 600 comprising housing 410, locking rod 210, removal rod 120, inserting rod 110, and applicator channel 420. FIG. 1 also shows bolt 220 which is inserted into housing 410. Some components of tool assembly 600 cannot be seen in FIG. 6 but are depicted in other figures, such as inserting rod cavity 440, removal rod cavity 450, locking channel 430, receiving channel 480, and removal channel 470 of tool block 400 in FIGS. 4 and 5. As depicted, locking rod 210 and bolt 220 are engaged as shown by lock and bolt assembly 300 in FIG. 3. As such, the longitudinal axis of locking rod 210 and the longitudinal axis of bolt 220 are perpendicular. Viewed from another perspective, the longitudinal axis of receiving channel 480 and the longitudinal axis of locking channel 430 are perpendicular.

(37) FIGS. 7 and 8 depict additional views of tool assembly 600 from FIG. 6. Similar numbered features have the same size, dimension, and orientation as discussed above.

(38) FIG. 10 depicts the same housing 410 and some components of tool assembly 600 as in FIGS. 6-8, albeit in tool assembly configuration 1000. As depicted, tool assembly configuration 1000 comprises bolt 220, locking rod 210, removal rod 120, and housing 410 having applicator channel 420. In tool assembly configuration 1000, bolt 220 is locked in position within housing 410 by locking rod 210, having the configuration of lock and bolt assembly 300 in FIG. 3. While in this position, extractor pin hole 226 is in alignment with applicator channel 420. In tool assembly configuration 1000, removal rod 120 has been pressed into applicator channel 420 until removal shoulder 124 abuts the portion of housing 410 adjacent to the opening to applicator channel 420. In this configuration, a portion of stem 126 has passed through applicator channel 420 and into extractor pin hole 226, thereby displacing extractor pin 224. When extractor pin 224 is displaced by removing stem 126, extractor pin 224 passes into removal channel 470 for collection.

(39) FIG. 10 can is also representative of the configuration of tool assembly 600 for inserting extractor pin 224 into extractor pin hole 226. In such tool assembly configurations, bolt 220 is locked in place in housing 410 by locking rod 210 and oriented as depicted in FIG. 10. Extractor pin 224 is then placed into applicator channel 420. Extractor pin 224 is then inserted into and seated in extractor pin hole 226, thereby coupling extractor 228 to bolt body 222. This is accomplished by driving extractor pin 224 into place by pressing inserting rod into applicator channel 420. Inserting stem 116 presses extracting pin 224 into extracting pin hole 226, until inserting stem is prevented from further insertion by inserting shoulder 114 abutting a portion of housing 410 adjacent to applicator channel 420. Viewed from another perspective, when inserting shoulder 114 abuts a portion of housing 410 adjacent applicator channel 420, inserting stem 116 has seated extracting pin 224 into place within extracting pin hole 226.

(40) FIG. 11 depicts an alternative embodiment of tools of the inventive subject matter. Specifically, tool 1100 depicted in FIG. 11 is contemplated as a compact embodiment of tools in the inventive subject matter. It should be appreciated that such compact designs offer reductions in the cost of manufacturing material, as well as increased ease of use and portability for a user.

(41) Similar to the embodiments discussed above, tool 1100 includes housing 1110 which includes applicator channel 1120, locking channel 1130, receiving channel 1140, and removal channel 1150. It is contemplated that firearm bolts be inserted into receiving channel 1140, preferably in a single orientation. Once inserted, a locking rod (as previously described) is inserted into locking channel 1130 to engage with the firearm bolt serving to both confirm that the bolt is in proper alignment for using the tool and to secure the bolt while the tool is in use. A removal rod (as previously described) may then be inserted into applicator channel 1120 and pressed to dislodge the extractor pin from the firearm bolt. Once the extractor pin is free from the firearm bolt, it will exit the tool through removal channel 1150, preferably into a receiving receptacle to prevent loss of the pin.

(42) It is contemplated that most firearm bolts that have an extractor and an extractor pin will also have a spring that pushes the extractor away from the bolt. This tension can cause misalignment of the extractor pin holes of the extractor and the bolt, causing difficulty when reinserting the extractor pin into the firearm bolt assembly (e.g., by an inserting as previously described). To prevent misalignment of the extractor pin holes, tool 1100 includes a raised portion 1142 of receiving channel 1140. Raised portion 1142 acts to depress the extractor pin into the firearm bolt assembly, thereby maintaining proper alignment of the extractor pin holes of the extractor and the bolt, and easing insertion of the extractor pin. As depicted in FIG. 11, it should be appreciated that the projection of an axis passing through channels 1120 and 1150 over an axis passing through channel 1130 will have an angle as described in FIG. 9B, preferably 22.5.

(43) FIGS. 12A-12C depict an alternative embodiment of tools in the inventive subject matter that include tool block 1200A, bottom lid 1200B, and top lid 1200C. Similar to previously discussed embodiments, tool block 1200A includes housing 1210 with applicator channel 1212, locking channel 1214, and receiving channel 1216. However, tool block 1200A further includes an accessory compartment 1218 as well as a lid resting rim 1219. Accessory compartment 1218 is designed to hold various tool components as depicted in the above embodiments (e.g., inserting rod 110, removal rod 120, locking rod 210, etc) as well as other firearm maintenance items (e.g., gun oil, wire brush, screw driver, swab, rag, etc.). As is further depicted below, lid resting rim 1219 acts as the coupling interface between tool block 1200A and bottom lid 1200B and top lid 1200C.

(44) As depicted in FIG. 12A (and FIG. 13C), it should be appreciated that the projection of an axis passing through channel 1212 over an axis passing through channel 1218 will have an angle as described in FIG. 9B, preferably 22.5.

(45) As depicted in FIG. 12B, bottom lid 1200B provides further advantageous features such as extractor pin compartment 1222 and compartment wall 1224. When in a closed or operational confirmation (FIGS. 13B and 13C, respectively) housing 1220 of bottom lid 1200B couples to tool block 1200A along block mating rim 1226 and lid resting rim 1219. When in such confirmation, extractor pin compartment 1222 of bottom lid 1200B is disposed below applicator channel 1212 of tool block 1200A, allowing extractor pin compartment 1222 to catch the extractor pin of a firearm bolt assembly when the pin has been dislodged from the bolt during use of the tool. In some embodiments, it is contemplated that extractor pin compartment 1222 is fitted with a magnetic strip to attract and secure the extractor pin once it has been removed from the firearm bolt assembly.

(46) As depicted in FIG. 12C, top lid 1200C has similar structure to bottom lid 1200B, including housing 1230 and block mating rim 1232. When in the tool assembly is in a closed confirmation (as in FIG. 13B), top lid 1200C is coupled to tool block 1200A along block mating rim 1232 and lid resting rim 1219. When in such confirmation, housing 1230 acts to enclose accessory compartment 1218 of tool block 1200A, securing tool components and other firearm maintenance items held within.

(47) FIG. 13A depicts open assembly 1300A of tool block 1200A, bottom lid 1200B, and top lid 1200C, and demonstrates the complimentary orientation of the various structures of 1200A, 1200B, and 1200C.

(48) FIG. 13B depicts closed assembly 1300B of tool block 1200A, bottom lid 1200B, and top lid 1200C. As is depicted and previously described, in closed assembly 1300B both bottom lid 1200B and top lid 1200C couple with tool block 1200A along lid resting rim 1219, thus enclosing tool block 1200A within bottom lid 1200B and top lid 1200C. In such confirmation, any tool components or firearm maintenance items are secured within closed assembly 1300B. Any appropriate means of coupling tool block 1200A to bottom lid 1200B and top lid 1200C are contemplated, including mechanical means (e.g., clasps, hooks, detents, hooks and loops, clamps, clips, latches, pins, etc), chemical means (e.g., adhesive, etc), or electro-magnetic means (e.g., permanent magnet, electromagnet, etc). It is contemplated tools of the inventive subject matter having closed configurations (as depicted in FIG. 13B) advantageously prevent foreign material (e.g., grit, dirt, sand, grease, etc) from collecting in the various channels of the contemplated tools or otherwise damaging or obstructing use of the tools.

(49) FIG. 13C depicts operating assembly 1300C. In this confirmation tool block 1200A is coupled to bottom lid 1200B along block mating rim 1226 and lid resting rim 1219. It is preferred that this confirmation is used when operating the tool, as extractor pin compartment 1222 of bottom lid 1200B is disposed below applicator channel 1212 of tool block 1200A, allowing extractor pin compartment 1222 to catch the extractor pin of a firearm bolt assembly when the pin has been dislodged from the bolt during use of the tool.

(50) It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms comprises and comprising should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
