ATTORNEY Patented Jan. 3Q, l 962 'its 3,018,578 PISTOL T BE WORN 0N THE WRIST u Edward T. Hill, 2221 S. Hoover St., Los Angeles 7, Calif. Filed Dec. 7, 1959, Ser. No. 857,940 Claims. (Cl. 42-13) The present invention relates to pistols, and specifically to a type of pistol adapted to be worn on the wrist and to be tired by movement of the hand. Primarily, the pistol of the invention is so carried on the wristy as to be unnoticeable when a coat is worn, and capable of instant use in an emergency. K Such an emergency might be a hold-up where the bandit searches the victim for a pistol without detection of the device of the present invention. p

The pistol of the present invention may fire regular ammunition, or it may be used for the liring of a war gas.

An object of the invention is to provide a pistol, particularly valuable in an emergency, and which may be brought into instant use upon movement of the hand of the person wearing the pistol.

A further object is -to provide a pistol of small size and efficient in operation.

A further object is the provision of a pistol easily worn by private detectives and others, of few parts, inexpensive in cost to manufacture, easily operated and which combines safety factors for its operation.

With the above mentioned and other objects in view, the invention consists in the novel and useful provision, formation, construction, association and relative arrangement of parts, members and features, all as shown in certain embodiments in the accompanying drawings, described generally, and more particularly pointed out in the claims.

In the drawings.

The pistol of the present invention may be mounted on different objects such as the flashlight casing shown in FIGURE 9, or the pistol may be mounted upon ay wrist strap, as shown in FIGURES 1 and 2, or it maybe attached `to 'various and sundryarticl'es to be carried by a person having need for a device of the Ytype of the present invention. n

The pistol of the present invention, reference being made to FIGURES 3, 4, 5 and 6, includes a barrel 1, breech mechanism 2, the latter includingv a trigger assembly 3, a safety lock assembly 4, and a firing pin assembly 5. The barrel has an ejector assembly 6.

2 The pistol casing is in two part-s, as shownrat4 7 and 8k, which parts are separable as illustrated in FIGURE 8, which is to say, the parts are relatively pivotable. The

vpistol casing is substantially a rectangular par'allelopiped 'in FIGURES 4, 5, and 6. This construction allows the pistol casing to be thin. The pistol casing part 7 has a T appearance, the barrel 1 forming the stem which extends forwardly of and intermediate the length of the vhead or transverse piece 9. The bore of the barrel extends through piece 9 with a counterbore at 10, which provides space for head 11 of the cartridge 12. As shown, the barrel is counte'rbored at 13 so as to accommodate the cartridge yshell in end abutment with an annular shoulder 14 which limits movement of the shell Within the counterbore 13, the main bore of the barrel being at 15 and of reduced diameter. No claim of invention is made for this type of barrel construction so far as the bores are concerned. One side or wing of head or piece 9, is bored and counterbored at 16 to accommodate a headed bolt 17 the shank of which is smooth in part and has a threaded end 18. The threaded end 1S is screwed into casing part 8. This construction permits part 7 to be swung laterally relative to part 8 in the manner shown in FIGURE 8. The opposite end of head or piece 9 is provided with an arcuate slot 19, there being a bolt 20 similar to the bolt 17 threaded as at 21 into the part 3. Adjoining the slot 19, the wall is rabbeted at 22 so that when the piece 9 is revolved on bolt 17 toward bolt 20, the bolt 20 and its head will enter the slot 19 and the rabbeted portion 22, as shown in FIGURE 4. The part 8 of the casing is provided with a longitudinal bore 30 intermediate the Width of the casing and with a transverse bore 31 which intersects bore 30. Parallelin'g the bore 30 and on both sides of said bore Sil are

bores

32 and 33, with the axes of the three bores all lying in the same plane. Bore 32 accommodates in part, the trigger assembly 3, while bore 33 accommodates, in part, the safety lock assembly 4, while bore 30 houses the tiring pin assembly 5, the bore 30' being in axial alignment with the barrel bore of part 7.

The firing pin assembly 5 includes a tiring pin body 4i) which is received within the bore 30, extends outwardly therefrom and terminates in a knurled nger piece 41. The firing pin body itl is cylindrical and provided with a reduced diameter tiring pin point 42. The tiring pin body carries a collar 44 having a diameter closely approximating the diameter of the bore 3@ but freely movable therein. An annular guide type nut 45 is threaded Within the end of the bore 30 for guiding movement of the firing pin body 40. Interposed between the collar '44 and the nut 45 is a tiring spring 46 which surrounds the pin body 40 and constantly urges the pin body in one direction. The bore 30 beyond the transverse bore 31 is reduced in diameter at 47 and accommodates a flanged bushing 48, the ange resting upon the flange 43 formed by the difference in

bore diameters

30 and 47. The tiring pin point 42 is received within the bore of the bushing. In this manner accuracy of movement of the tiring pin point is assured, as it is supported between the bushing 48 and the guide nut 45.

The trigger assembly 3 and the safety lock assembly 4 are similar in construction. The trigger assembly 3 intaludes a bolt Slil which carries a collar 51, the bolt and the collar being received within bore 32. One end of the bolt 50 is received with a guide nut 52 which is posi- 'tioned on one side of the collar 51, the nut being threaded within said bore. The opposite end of the bolt 50 has a conical portion 53` which functions as a cam, as hereinafter described. Extending from the apex of the conical portion 53 is a reduced diameter stem 54 passed through a bore 55 and joined with a further length of stem of larger diameter 56, which extends through an axial bore in the cap bolt 20. The bore 55 is slightly larger in diameter than the diameter of the stem 56 to permit movement of stem 56 within said bore. The bolt 50 is guided at one end in its slide movement by a guide nut 52 and at its opposite end by a reduction in bore diameter, as shown at 57. Interposed between collar 51 and the ledge formed by the difference in

bore diameters

32 and 57 and surrounding the bolt, is a coil spring 58 which normally urges the bolt and associated stems 54 and 56 to the position shown in FIGURE 4.

The safety lock assembly 4 is identically constructed with that of the trigger assembly 3, for which reason the same numerals will apply for the safety lock assembly as applied to the trigger assembly.

The transverse bore 31 accommodates, in the case of the trigger assembly 3, a sear 60 provided with a diametric or transverse bore 61 and a conical counterbore 62. One end of sear 60 has a cylindrical socket 63 while the opposite end is provided with a substantially diametrical sear catch 64, one side Wall 65 of which is in substantially right angular relationship to the plane of the end of the sear 60 while an opposite side wall 66 of the sear catch is at an angle to the plane of the end of the sear, the angle being other than 90 to provide a cam surface. The outermost surface 67 of the sear catch is parallel to the plane of the end of the sear. A counterbore 68 at one end of the bore 31 receives a pressed fit cap 69 and interposed between said cap and received within said cylindrical socket 63 is a sear spring 70. Viewing FIGURE 4, it will be observed that the spring 70 urges the sear 60 -to move in one direction, that is, inwardly of the casing part 8, and in so doing the bounding wall of the conical counterbore 62 'is brought into engagement with the conical portion 53 of bolt 50. Hence, if the bolt 50 which includes

pins

54 and 56 are moved to the left of FIGURE 4, or outwardly of casing part 7, the sear 60 would be cammed outwardly of bore 31 to compress the spring 70, as shown in FIGURE 6. Immediately upon releasing the pin 56, the spring 58 will again urge the bolt 50 and the

pins

54 and 56 inwardly so that the position for the parts will be that shown in FIGURE 4.

It will be observed that the sear catch member 64 normally projects within the bore 30 so that the wall 65 enages the collar 44 of the firing pin body, while for the safety lock assembly, the wall 65 of the sear catch 64, will engage the collar 44 in advance of any engagement of the collar with the sear catch 64 of the trigger assembly. As the portions just described for the trigger assembly are identical for the safety lock assembly, the same numbers of reference will apply.

FIGURES 1, 2, and 3 show that the parts 7 and 8 of the pistol casing, are each provided with

top enlargements

80 and 81, enlargement 81 being formed on the barrel while the enlargement 80 is formed on the portion 8. These enlargements may take any configuration desired so as not to detract from the appearance of the pistol. The enlargement 81 is bored inwardly at 82 from the end facing the portion 80 to accommodate a spring pressed bolt 83 which bolt has a transverse portion 84 for engagement with the cartridge head to partly eject the cartridge from the barrel when the parts 7 and 8 are separated, as shown in FIGURE 8. A headed pin 85 is secured to portion 84, being passed through a slot in the top of the enlargement so that the linger may engage the head of the pin to move the bolt within bore 82 to compress the bolt spring. The enlargement 80 is bored and houses a spring pressed ball detent 86. The bolt 83 is provided with a socket 87 on its outer end wall for receiving the ball of said detent, as shown in FIGURE 3. Thus when the parts are swung together from the position of FIGURE 8 to that of FIGURE 3, the ball detent will enter the socket 87 and hold the parts in juxtaposition.

The barrel has secured thereto a blast deector plate which extends upwardly at an angle to the bore of the barrel and forwardly of the muzzle end of the barrel, as shown in FIGURE 3. The pistol as an entirety may be mounted on various objects such as on the wrist strap shown at 101, the strap encircling the wrist, as shown in FIGURE 1, and secured in the ordinary manner, that is, by buckles, as shown in FIGURE 2.

The outer ends of the pins 56 for both the trigger assembly and the safety arm assembly, are provided with rings 102 to which is attached ends of a lanyard chain 103.

The construction of the pistol in FIGURES 9 and l0 remains the same with the exception that extended pins 56 are not utilized and for moving the pins 50, knurl headed bolts 104 are passed through slots 105 in the pistol portion 8 for threaded engagement within threaded bores of the bolts 50. The pistol of the type shown in FIG- URES 9 and 10 may be mounted on any object desired such as the flashlight casing shown in FIGURE 9, and a strip 106 may be secured to the pistol casing and to the ashlight casing.

The operation, uses and advantages of the invention just described, are as follows.

Assuming that the wrist strap is utilized, as shown in FIGURE l, and that a cartridge has been placed within the barrel as shown in FIGURES 3 to 6 inclusive, in FIGURE 4 the ring pin point is held against any movement that would re the cartridge for the reason that the spring 46 is not under firing compression and the collar 44 is in a position so as to engage wall 65 of the sear 64 for both the trigger assembly and the safety lock assembly, although in the showing of FIGURE 4, the collar engages the wall 65 of the safety lock assembly. In order to re the cartridge, the safety lock assembly must be released which means that the sear catch wall 65 is moved from engagement with the collar 44. Such release is accomplished by moving the bolt 50, and pins 44 and 56 outwardly by pulling upon one end of lanyard chain 103 connected to the pin 56 of the safety lock assembly. This moves the sear 60 to the position of FIGURE 5. The firing pin point will move forwardly, the collar 44 engaging the sear catch Wall 65 of the trigger assembly. Upon pulling the opposite length of chain 103, the bolt and pins of the trigger assembly are moved forwardly which cams the sear 60 outwardly and releases collar -44 from engagement with the wall 65 of the sear catch or to the position shown in FIGURE 6. This permits the firing pin point to strike the firing head of the cartridge to explode the same. To recock the ring pin assembly, the firing pin body 40 is moved outwardly by grasping the finger piece 41 and the collar 44, which has an annular beveled edge 120, will engage the cam walls 66 of each sear catch to move the sears outwardly thus permitting the collar 44 to move to the position shown in FIGURE 4.

The operation is the same for that type of the device shown in FIGURES 9 and 10, save and except that instead of moving lengths of chain, the bolts 104 are moved.

In FIGURE l I have shown the chain as passed under the index finger. Thus the operator may, by moving the hand slightly, pull on one length or the other of the chain and in so doing the safety pin assembly releases the ring pin point and the firing pin point is then actuated by pulling on the other length of the chain of the trigger assembly.
