Speed loader for T-shirt gatling gun

Abstract

A T-shirt Gatling gun speed loader that includes a series of tubes that mate with the tubes of a T-shirt Gatling gun. T-shirts to be loaded into the T-shirt Gatling gun are located in the speed loader tubes. A series of pushrods are located coaxially with the speed loader tubes and extend for a distance that is approximately the length of the tubes of the T-shirt Gatling gun. These pushrods are mounted at a second end to a push plate so that by inserting the speed loader tubes into the T-shirt Gatling gun tubes and pushing the push plate, the T-shirts are loaded into the T-shirt Gatling gun at a distance to allow proper firing of the T-shirts. The speed loader is then withdrawn from the T-shirt Gatling gun.

DETAILED DESCRIPTION

(13) A T-shirt Gatling gun 100 according to the prior art is shown in FIGS. 1 and 2. A series of tubes 102 are circumferentially located around a central axis. The tubes 102 are used to receive the T-shirts and to provide a barrel for shooting the T-shirts. Preferably the tubes 102 are a clear plastic material. The tubes 102 have a given diameter and thickness so that the tubes 102 have an inner diameter and an outer diameter. The tubes 102 also have a given length and an axis. The tubes 102 are affixed on a circular end plate 104, the central axis being at the center of the end plate 104. A circular retaining plate 106 having a series of circumferential holes to align with the tubes 102 is provided a spaced distance from the end plate 104 to allow the tubes 102 to be securely held. A fixed plate 108 is provided behind the end plate 104 and is used in cooperation with a firing assembly (not shown) to fire a T-shirt from a given tube 102.

(14) A crank no has a belt 112 connected to a wheel 114. The wheel 114 has an axle (not shown) mounted at the center of the end plate 104 and passing through the fixed plate 108. When the operator cranks the crank no, the end plate 104 and the tubes 102 rotate. A trigger assembly 116 is provided to coordinate the firing of the T-shirts from the T-shirt Gatling gun 100. A button (not shown) on the trigger assembly 116 is held down while the crank no is turned and then as the end plate 104 passes the firing assembly the T-shirt in the particular tube 102 is shot from the T-shirt Gatling gun 100.

(15) In the illustrated embodiment, an upper stand portion 118 is connected to the plate 108 and is connected to a tripod 120, which includes a upper support 122 and three legs 124. A compressed gas cylinder 126 is located on one of the legs 124 and includes a hose 128 leading to the firing assembly to provide the compressed gas to fire the T-shirts.

(16) Briefly, as the crank no is rotated, the tubes 102 rotated around the central axis of the assembly and fire as each tube 102 passes the firing assembly. This allows a rapid firing of T-shirts from the T-shirt Gatling gun 100 to the great pleasure of the audience.

(17) A speed loader 300 according to the present invention is shown in FIG. 3. A series of tubes 302 are circumferentially located around a central axis and are mounted to a cylindrical plate 304, the center of the plate 304 aligning with the central axis. The tubes 302 have an axis, a given diameter and a thickness so that the tubes 302 have an inner diameter and an outer diameter. The tube 302 outer diameter is less than the tube 102 inner diameter to allow the tubes 302 to be inserted into the tubes 102. A series of pushrods 306, one for each tube 302 and preferably aligned with the axis of the tube 302, are mounted to a push plate 308 and pass through an opening in the plate 304.

(18) Briefly, T-shirts are placed into the tubes 302, the speed loader 300 is positioned on the T-shirt Gatling gun 100, the push plate 308 is depressed and the pushrods 306 travel down the length of the T-shirt Gatling gun tubes 102 to place the T-shirts in the proper location for firing. The speed loader 300 is then withdrawn from the T-shirt Gatling gun 100.

(19) FIG. 4 illustrates the relationship of the T-shirt Gatling gun 100 and the speed loader 300. As can be seen, the tubes 302 of the speed loader 300 mate with the tubes 102 of the T-shirt Gatling gun 100 to allow the tubes 302 and 102 to be properly lined up and have the T-shirts readily in the proper location when the push plate 308 is pushed.

(20) The relationship between the tubes 102 and the tubes 302 is better illustrated in FIG. 5. In the illustration, a speed loader tube 302 is located inside and at the open end of a T-shirt Gatling gun tube 102. It can be seen that the outer diameter of the speed loader tube 302 is slightly smaller than the inner diameter of the T-shirt Gatling gun tube 102 to allow the tubes 302 be readily inserted into the tubes 102. A T-shirt 500 is located in the speed loader tube 302. An end plate 502 is connected to the pushrod 306 and is located inside the tube 302 to provide a surface area to push the T-shirt 500. The end plate 502 is sized to slide easily inside both tubes 302 and 102. A nut 504 holds the plate 502 onto the pushrod 306 to secure the assembly.

(21) FIG. 6 is an illustration of a T-shirt Gatling gun tube 102 when the pushrod 306 is fully extended into the tube 102, so that the T-shirt 500 is now at the bottom of the tube 102 in a firing position. It is noted that the T-shirt 500 may be slightly snuggly held in the tube 302 but that is desirable as it allows the T-shirts to be more positively retained in the relatively short tubes 302 as compared to the long tubes 102.

(22) FIG. 7 illustrates the speed loader 300 in the fully retracted position where the pushrods 306 are fully retracted from the plate 304, so that the plates 502 are effectively in contact with the plate 304 and ready for insertion of the T-shirts 500. As can be seen, the pushrods 306 are preferably much longer than the tubes 302 and are of a length such that when fully extended into the tubes 102, the plates 502 are effectively a T-shirt distance away from the plate 104.

(23) In FIG. 8 the pushrods 306 are fully extended and the push plate 308 is in contact or near contact with the plate 304. The push plate 308 is pulled away from the plate 304 and the pushrods 306 retract. There may be some difficulty getting the end plates 502 back into the tubes 302, but this is not a concern as the reloading of the speed loader 300 can be done during breaks when the reloading time is not critical.

(24) Depending upon the particular materials chosen for the pushrods 306 and their actual length, there may be a tendency to have the plate 308 rack with regard to the plate 304, which may hinder pushing of the T-shirts 500 into the tubes 102. To address this concern, an anti-racking cylinder 902 can be provided as shown in FIG. 9. The cylinder 902 is attached to the plate 304, preferably inside the ring of the tubes 302. The cylinder 902 is rigidly mounted to the plate 304 and includes a closed end 904. A series of guide tubes 906 are located inside the cylinder 902 and extend from the plate 304 to the end 904. Preferably the guide tubes 906 are firmly mounted at both ends. A series of guide rods 908 are mounted to the plate 308 and inserted through the plate 304 into the guide tubes 906. Preferably the clearance between the guide rods 908 and the inner diameter of the guide tubes 906 is nominal to allow a positive retention with limited slop. By having the cylinder 902 firmly mounted to the plate 304, the guide tubes 906 provide a secure foundation for the guide rods 908, to limit any potential racking of the plate 308 with respect to the plate 304.

(25) FIG. 10 is a perspective view of the T-shirt Gatling gun 100 in conjunction with a speed loader 300 which includes the cylinder 902. As can be seen, the cylinder 902 fits inside the circle of the tubes 102 and is preferably of a length that does not bottom out on the plate 104 when the speed loader 300 is in position for loading.

(26) In some cases, it may be difficult to align the tubes 302 and 102, in the illustrated example 12 tubes, if all of the tubes are finished at their open ends perpendicular to the their axis. Figure n illustrates an alternate embodiment of tubes 302 where the protruding ends of the tubes 302 are not cut perpendicular to the axis of the tubes 302 but rather have an angle such that the end surfaces of the tubes 302 are angled with respect to the plane of the end of the tubes 102 to allow faster alignment in the tubes 102. While a single angle is shown, it is understood that various alternatives could be used to finish the ends of the tubes 302 to allow improved registration.

(27) The use of the speed loader 300 with the T-shirt Gatling gun 100 is straightforward. The speed loader 300 has the pushrods 306 fully retracted and T-shirts 500 loaded into the tubes 302. After a full round of T-shirts has been fired from the T-shirt Gatling gun 100 and it is now empty, the speed loader 300 fully loaded with the T-shirts 500 has the tubes 302 registered with the tubes 102 of the T-shirt Gatling gun 100 and the push plate 308 is depressed, thus extending the pushrods 306 and the T-shirts 500 into the tubes 102. When the push plate 308 is fully pushed and T-shirts 500 are properly located, the speed loader 300 is simply withdrawn from the T-shirt Gatling gun 100 and placed aside. This allows significantly faster loading of the loading of the T-shirt Gatling gun 100 as compared to manually trying to insert T-shirts individually into each one of the tubes 102. If desired, a series of speed loaders 300 can be readied to allow extremely long firing times of the T-shirt Gatling gun 100.

(28) While T-shirts have been used as the example object, it is understood that many other objects can be used, such as stress balls, miniature footballs and the like. While the examples have used a single ring of 12 tubes, it is understood that other numbers of tubes could be used and multiple rings of tubes could be used, with the speed loader matching the tube configuration of the Gatling gun.

(29) In certain designs of T-shirt Gatling guns, the end of the Gatling gun is not completely open as in the illustrated embodiment but a mechanism is present across the end to hold a rotation point and extending tubes for firing the T-shirts. In such a case, a fully circular speed loader as disclosed in the preferred embodiments will not be usable. In such a case, a speed loader that is just an arc or pie-shaped segment of the full circular design can be used to load T-shirts into a portion of the exposed tubes. Even with the then required multiple loadings, operation is still much faster than entirely manual operations.

(30) While no specific materials have been discussed, other than a preference of clear plastic for the tubes 102, it is understood that a variety of materials can be used for the various items. The various plates can be formed of wood, plastic or metal, though plastic is preferred for weight savings. The pushrods can be threaded metal rods or smooth rods with threaded ends. The various items can be affixed to the plates using various methods, such as glues or threading. The guide rods are preferably smooth rods but need not be metal. A handle could be applied to the push plate 308 to aid pushing, withdrawal and retraction. Other variations of the materials will be apparent to one skilled in the art.

(31) The above description is intended to be illustrative, and not restrictive. For example, the above-described embodiments may be used in combination with each other. Many other embodiments will be apparent to those of skill in the art upon reviewing the above description. The scope of the invention should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. In the appended claims, the terms including and in which are used as the plain-English equivalents of the respective terms comprising and wherein.
