[0033] In another example, the first member 102 can be coupled with the second member 104. For example, the apparatus 100 can include a third member 116 that can operably couple the first member 102 with the second member 104. In one embodiment, a screw 126 or rivet 126 can securely attached the first member 102 to the third member 116; in another embodiment, a screw 128 or rivet 128 can securely attach the second member 104 to the third member 116. In one embodiment, the third member 116 can have two constituents, such as can be seen in
[0034] In one embodiment, the apparatus 100 can be configured to engage a bedplate or engine of a locomotive. For example, the first member 102 can include a notch 118 or rounded notch 118 that can facilitate the coupling of the apparatus 100 around a locomotive component, such as a pipe, conduit box, or any other component. In another example, the first member 102 can have a hole, slant, or any other design or configuration suitable to allow the apparatus 100 to couple to a car body around a train component. In another embodiment, the second member 104 can include a chamfered corner 124 or chamfered corners 124 that can facilitate the engagement of the second member 104 and apparatus 100 with an engine, an example of which can be seen in
[0035] Preferably, the apparatus 100 can be configured to engage a locomotive on the conductor side of the locomotive; for example, the apparatus 100 can be a conductor-side jig 100. For example, the apparatus 100 can be configured to enable orientation of the apparatus 100 such that the second member 104 can contact a locomotive with the first member 102 extending therefrom, and a longitudinal axis of the first member 102 can be substantially parallel with a longitudinal axis of a locomotive (and substantially perpendicular to a lateral axis of the locomotive).

[0036]
[0037] In another embodiment, the dowel openings 206 can be configured to receive a bushing 220. For example, a dowel opening 206 can be of a pre-determined diameter, such that a bushing 220 can be inserted into the opening 206. In one embodiment, the bushing 220 can engage within the opening(s) 206 of the second member 204. For example, an outer diameter of the bushing 220 can be similar to an inner diameter of an opening 206, such that the bushing 220 can be snugly fitted within the opening 206, such as to restrict unwanted rotational movement of the bushing 220. In another example, the second member can include bushing pins 208 or screws 208 configured to engage a bushing 220. For example, the pins 208 can have a head sized to match a notch on a bushing 220, such that rotational movement can be restricted by the bushing pin 208. Preferably, the apparatus 200 can have five dowel openings 206. In another embodiment, the apparatus 200 can have three busing pins 208. In one embodiment, the second member 204 can have five openings 206 and three pins 208, and the pins 208 can be located strategically such that a bushing 220 located within any one of the openings 206 can have a pin 208 available to engage. In another embodiment, the apparatus 200 can include any number or combination of openings 206 and pins 208, such that any bushing engaged with the apparatus 200 can be engaged with a pin 208.
[0038] Preferably, the apparatus 200 can be configured to engage a locomotive on an engineer side; for example, the apparatus 200 can be an engineer-side jig 200. For example, the apparatus 200 can be configured to enable orientation of the apparatus 200 such that the second member 204 can contact a locomotive with the first member 202 extending therefrom, and a longitudinal axis of the first member 202 can be substantially parallel with a longitudinal axis of a locomotive (and substantially perpendicular to a lateral axis of the locomotive). In another embodiment, the first member 202 can be configured to accommodate locomotive or train components generally found on an engineer side of a locomotive. For example, the first member 202 can be a raised platform operable to cover a locomotive component and provide a platform on which to set a mag drill. In another example, the first member 202 can include multiple jacking bolt holes 222 each capable of receiving a jacking bolt 214, such that the jacking bolt 214 placement can be customized to accommodate a surface extending thereunder. In another embodiment, the second member 204 can include chamfers 224 that can correspond to edges or corners found on an engine or bedplate or a component mounted thereto on an engineer side of a locomotive. In one embodiment, the first member 202 can include a straight edge 218 that can, for example, maximize the surface area of the first member 202 to facilitate the coupling of a drill thereto, such as over a locomotive component.

[0042]
[0043] In another embodiment, the jig 504 can provide a platform to which a mag drill can attach while drilling, supporting the drill over a component 518. In one embodiment,
[0044] In another embodiment, the system 500 or method can include a jig 504 that includes one or more openings 506. For example, the openings 506 can be configured to receive a bushing 508, which can be similar to bushing 120, 220, or 300 discussed above. In one embodiment, the jig 504 of the system 500 can further include a bushing pin 510 configured to operably couple the bushing 508. In another embodiment, one or more of the openings 506 can be configured to circumscribe an engine mounting bolt 502 such that the bolt 502 can remain securing the engine 516 to the bedplate 522 while a dowel hole is drilled utilizing the system 500. In this manner, the engine attached to the engine 516 can remain secured in place by at least one engine mounting bolt 502, such as to prevent misalignment of engine 516 components with the locomotive or bedplate 522 while a hole is being drilled. In another embodiment, a drilling area within at least one opening can be identified. For example, a hole can be drilled in an opening 506 where there is no hole in the engine base aligning with the jig opening, such that a hole can be drilled in the engine base via the jig opening. In another embodiment, the system 500 can include a jacking bolt 512 configured to stabilize the system as it is attached to the engine 516. For example, the jacking bolt 512 can be operably coupled to the system 500 in a manner that allows the jacking bolt 512 to travel both vertically and horizontally (e.g., jacking bolt 114 and 214 in
[0045]
[0046] In another embodiment, the system 600 can provide a plurality of areas 606 or openings 606 in which dowel holes can be fabricated. For example, any one of the available dowel openings 606 can receive the bushing 608 (or a bushing similar to bushing 608) to facilitate the drilling of a dowel hole therein. In another embodiment, any one of the dowel openings 606 can be configured to overlay and circumscribe a head of an engine mounting bolt, and the unoccupied dowel openings 606 can then be fitted with a bushing 608 and facilitate the drilling of a dowel hole. In this manner, the system 600 can provide multiple points at which drilling can be enabled with the system 600 while the engine remains secured via one or more engine mounting bolts.
[0047]
[0048]
[0049] In another example, a first drill bit 802 can be used as a pilot bit, a second drill bit 802 can be used widen the pilot hole, and the third bit 802 can be used to ream the hole; in one embodiment, each bit 802 can have a corresponding bushing 804, and each bushing 804 can be operably coupled to either jig. In another embodiment, the dowels 806 can be used interchangeably between any holes created using the kit 800, because the kit 800 can, for example, standardize the dowel hole fabrication process. In another embodiment, the magnet 812 can be used to collect metal shavings created during drilling, and the lubricant 810 can be used to lubricate any or all of the drill bits 802 during drilling. In another embodiment, any suitable number of constituents can be included in the kit 800 to enable the drilling of dowel holes on the engineer and/or conductor side of a locomotive.
[0050] In one embodiment, the drill bits 802 can be ⅜-inch (⅜″ 2), ⅞-inch (⅞″ 2), and 15/16-inch ( 15/16″ 4) drill bits. In another embodiment, the drill bits 802 can include a ⅜″ 2 flute parabolic drill bit, a ⅞″ 2 flute bit, and a 15/16″ 4 flute drill 8.5″ OAL drill bit; in another embodiment, the bushings 804 can be configured to correspond to these drill bits 802. In another embodiment, the dowels 806 can be 0.940-inch (0.940″) dowels 806; in another embodiment, the dowels 806 can includes nuts or heads. In another embodiment, the kit 800 can include a drill, such as a mag drill known in the art; in another embodiment, the kit 800 can include one or more washers. For example, the kit 800 can include hardened steel washers, 1- 1/32-inch (1 1/32″) inner-diameter (ID) and 2-inch (2″) outer-diameter (OD); in another example, the kit 800 can include four of these washers, or one washer for each dowel 806. In another embodiment, the kit 800 can include an air hammer (to, e.g., drive the dowel 806), a telescoping gauge (snap gauge) (to, e.g., measure internal diameter of the hole), 1-inch (1″) micrometer (to measure, e.g., the dowel size), a lifting eye that can couple with one or both of the engineer- and conductor-side jigs, and/or a 1-½-inch (1½ ″) ¾-inch (¾″) drive six (6) point socket (to, e.g., facilitate removal and/or reinstallation of an engine mounting bolt and/or jig bolt).
[0051] In one embodiment, the drill jigs and drilling systems disclosed herein can facilitate the standardization of dowel holes in locomotive engines. For example, the conductor-side jig and engineer-side jig can each be standardized for one or more types of locomotive engines (such as EMD engines), such that the jig bolt hole can be operable to enable coupling of the jig to a given engine via an engine mounting bolt hole. In another example, dowel openings and bushings can be of standard sizes to accommodate standard drill bits. For example, bushings with different sized drill cavities can be operably coupled the jig, such that holes of different sizes can be drilled using the same jig by simply changing the bushing. In another embodiment, the second member can be configured (such as via the chamfers) to be operably coupled to an engine on either the conductor or engineer side. In one embodiment, the first member can be located a pre-determined distance above a second member such that the first member can overlay a component on an engineer or conductor side of a locomotive engine while the second member is coupled to the engine. In another embodiment, the first member can be configured to accommodate components commonly found on either the engineer or locomotive side, such as by including a cut, notch, or indention in the first member that a locomotive component can protrude through or around.
[0052] In one example, the jig apparatuses and systems can increase safety in drilling dowel holes by providing an area on which a drill can rest or attach for stability during drilling; such stabilizing can be accomplished via the coupling of the jig to the engine (e.g., via a jig bolt) and/or, e.g., adjusting a jacking bolt to contact a surface. In one example, an engineer-side jig and conductor-side jig can be considered like left and right hands, such that they can be substantially mirror images of one another while not being super-imposable on one another.
[0053] In another embodiment, the methods, systems, and apparatuses discussed herein can be utilized to create or fabricate holes in any given rail car. For example, a jig can be operably coupled to a specific area on a train that requires drilled holes, such that the jig can be used to make uniform holes at the same location on multiple engines or locomotive car bodies. In another embodiment, the jigs described herein can be made of steel or any other material suitable to enable the jig to facilitate drilling of holes in a rail car or locomotive. Bushings and/or bushing pins described herein can similarly made of steel or any other material suitable to enable drilling in a rail car or locomotive. Preferably, the bushings described herein (and the corresponding openings or dowel openings) can be configured to accommodate at least a ⅜-inch (⅜″ 2), ⅞-inch (⅞″ 2, and 15/16-inch ( 15/16″ 4) drill bits, as well as any other size drill bit; in another embodiment, the bushings can accommodate flute parabolic drill bits, flute drill bits, finishing bits, or any other types of drill bits. In another embodiment, different bushings can be used for different sized drill bits, and each different bushing can be operably coupled to the same jig.
[0054] The present disclosure achieves at least the following advantages: [0055] 1. Standardizing dowel holes and dowels for engine attachment; [0056] 2. Increasing the safety of drilling dowel holes; [0057] 3. Providing a drill jig that enables both the standardization of the dowel placement and drill attachment; [0058] 4. Preventing bushing movement by providing a jig that can be operably coupled a bushing; [0059] 5. Providing a jig that can include multiple removably-attached members, such that damaged members can be replaced with new members without requiring replacement of the entire jig; [0060] 6. Enabling the fabrication of dowel holes in an engine while maintaining alignment of the engine (such as via an engine mounting bolt that a jig can be coupled over); [0061] 7. Providing, via a jig, multiple locations in which a dowel hole can be drilled; [0062] 8. Facilitating the lifting and placement of a jig by enabling the attachment of a lifting eye; [0063] 9. Increasing the efficiency of dowel hole drilling by standardizing the method, procedure, and requirement components; and [0064] 10. Eliminating the need to weld existing dowel holes prior to dowel replacement by providing multiple locations at which new dowel holes can be drilled.
[0065] Persons skilled in the art will readily understand that these advantages (as well as the advantages indicated in the summary) and the objectives of this system would not be possible without the particular combination of hardware and other structural components and mechanisms assembled in this inventive system and described herein.
