the Woods Patent 1,073,312. The purpose of these' devices is concealment and surprise against holdups and the like, and they do not involve physical contact with the adversary.

My device, on the contrary is not primarily intended to be concealed, although it may be if so desired, and the purpose is to provide the wearer with a lethal weapon which he may keep attached to his person at all times without undue diiculty. Modern warfare, with its inltration tactics and surprise, entails considerable hand to hand fighting. Due to the surprise nature of these attacks, the attacked personnel are frequently caught comparatively unarmed, in that they have laid aside their normal arms while engaged in other duties, or while sleeping, etc.

The device, in the illustrated embodiment is in the form of a firearm which is worn on the back of the hand, and has its trigger projecting in the direction of the iingers. The barrel substantially parallels the direction of the fingers. When the fist is doubled up, the trigger is exposed for contact and the lingers are removed from the line of re of the lethal charge of the weapon. Thus when the wearer becomes engaged in hand to hand fighting and his other weapons such as rifle or bayonet are ineffective, he need only double up the st of the hand to which the weapon is attached, and strike his adversary'. Even though l,the trigger of the weapon is not struck against a vital organ of the adversary, such as the head or abdomen, the nature of the lethal charge at these close quarters is such that the adversary will be instantly knocked out or disabled, because the weapon is loaded with a shotgun shell, and the shattering eiect of such a shell, particularly at close range, is Well known. The Weapon contains only a single shell, and while it can be reloaded easily, it may not be possible to do so during the same action, but since it remains attached to the hand it is still a very eective brass knuckle in subsequent fighting.

It is accordingly the primary object of my invention to provide a novel firearm which is adapted to be worn at all times, and with which a lethal charge can be discharged into an adversary by pressing or striking the Weapon against him.

Another purpose of the invention is the provision of a novel weapon which discharges its charge into an object when the trigger is pressed or struck against the object. p

Another object is the provision of a novel firearm adapted to be worn on the back of the hand and discharged by striking orv pressing its trigger against an object or adversary, there being a safety device operable to prevent the inadvertent discharge of the gun when the safety is on..

Still further objects of the invention will appear as the description thereof proceeds with reference to the accompanying drawings, in which:

The gun is made of metal throughout, and comprises a base I2, shown substantially stripped in Fig. 2. The base I2 comprises a at portion which is fastened to the back of the hand or glove as shown in Fig. 1. Integral with or securely fastened .to the base I2 is a shoulder I3 which has a longitudinal threaded bore I #extending parallel angles to the base, as by machine screws I8 and I9 passing through lugs-20 and 2! which are, integral with the plate, the screws engaging tapped holes in the base I2.. The plate I'I has a-,holelg therethrough, in axial alignment with the .bores I4 and I6 in shoulder I3 and breechV blocki i5.

A trigger tube 23, threaded at one endmto engage the threaded bore I4 in the shoulder I3, extends the length of the' base `1I 2 and'ipas'ses through the bore I6 and the holey 22, with both of `which it has a fairly close t.

The firing :pin is cf Ya length. extending past the plate Hand has a knobv 55 threadedon its outer end. YThe firing pin has Y.anenlarged .portion which slides in the bore 52,fand an external `flange 55 which slides `the largebore! inthebush- `ing .55. A spring.-5l iscompressedbetween-tm -flange 55.011. the-.tiring pin and theshoulder 53, thus urging. thering .pin .to rthe fleft. vBeyond Athe enlarged portion .whichslides .in bore 52, the firing pin diameter is reduced to form a shoulder `-`58 and ,passes .througha-.bushing .59 which slides vthroug'fh the holeflin plateI'I. .The bushing 59 is clamped to theringpin between .the shoulder T58 ,and the knob55.

.,In'Ffig. ,6 is shown aperspective viewof asear Si havlflrg a latch 62 which is springpressed against the shoulder- 5i? to holdthe ring pinin the cocked position shown ,in Fig. 11. An eye bolt `63 appearing in Figs. 4 and 9 has its threaded .portion Y(it screwed `into a threaded hole inthe 'breech'block 55. The bolt has two spaced eyes, v a pin( E5 passing through one and having thready-ed engagement'withl the other. "The searftl has ahole 66 through which the-pin. 55 passes, the sear 5I beingthus'pivoted about'thepinfE. As

Y`shown infFig. 9,:there is a blind hole `I'I vin the bottomzof the scar, and a Coil spring'G .which .is 75..sea.t'ed inl this'hole bears .againstthe top lof the base l2, thus normally raising the free end of the sear 5I. When the rng pin is drawn back to the cocked position of Fig. 11, the spring 68 forces the latch 52 upwards whereupon it is held in resilient engagement with the shoulder 60 by the combined action of springs 51 and S8. The top of the sear has a recess with an upwardly sweeping top surface or cam S9. As best shown in Figs. 4, 9 and 11, the lug 21 which projects from the trigger bar 2-5 extends over the cam 69. When the trigger 25 is moved backwards by a thrust on the button 2S, the lug 21 engages the cam @s to force the sear and latch 62 downwards against the force of spring 58. When the sear has been sufficiently depressed, the latch 62 is disengaged from the shoulder 50, and the firing pin will y to the left to explode the shell. rIhus the gun is cocked by pulling the firing pin back by means of the knob 55 until the latch 62 engages the shoulder Si). rfhe gun may be discharged by pushing on or striking the trigger bar button 25.

A round post 1E) is threaded into the base I2 and extends vertically upwards therefrom between the bushing 5S and the scar 5l as shown most clearly in Figs. '7 and 4. The diameter of the post is too great for it to t between these two elements, so a circular cut is milled in the side facing the bushing 59, the diameter of the cut being substantially the same as that of the bushing so that the bushing bears against substantially the whole area of the cut in the post. The post 1@ thus forms a brace or guide preventing sideways movement of the free end of the sear 6l.

Safety means are provided to prevent accidental discharge of the gun while it is cocked. Such means are desirable because while it is intended that the gun be worn and in readiness for use substantially all of the time, there are occasions when the trigger button 25 might be struck unintentionally, as when the wearer is working with his hands, or when asleep, etc.

The safety means is shown particularly in Figs. 4 and 12. It comprises a lever which is L shaped in plan and pivoted about a screw 1l which is threaded into the base l2, the lever itself lying flat upon the base. At its exterior end the lever has a button 12 which enables the wearer to move the lever. When the safety is in the locked position, its end 13 lies under the scar 62 as shown in Fig. 12. As is apparent from Figs. 10 and 11, the safety cannot pass under the sear to lock it unless the firing pin is cocked because there is not room under the sear for the end 13. When the iiring pin is cocked, as in Figs. 11 and 12 and with the safety in the on position of Fig. 12, the sear 6l cannot be depressed by moving the trigger bar backwards, because with the end 13 of the safety under the latch 62, the latch is held thereby against downward movement. Similarly the trigger bar 25 cannot be pushed back for its normal stroke. Thus after the gun is loaded by the insertion of a shell as in Fig. 5, and the rng pin is cocked by pulling back on the knob 55, the safety can be pushed into the on position shown in Fig. 12, or it can be left in the 01T position of Fig. 4.

A spring pressed detent as shown in Fig. 13 may be used to hold the safety in either its on or oir position. The knob 12 has a bore containing a spring 1li and a ball 15 which are retained in the bore by reducing the diameter of the hole at its lower end to a diameter less than that of the ball 15. The base l2 is provided with depressions 16 and 11 into which the protruding portion of ball 15 fits when the safety lever is in the on or olf position respectively. Thus the safety lever will not shift from either position unless it is pushed hard'enough to overcome the spring pressed detent.

The mechanism between the breech block I5 and the plate l1 is protected by a cover plate 18, shown in section in Fig. 7. Defending side portions 1S of the cover plate extend to the base E2 and the entire cover plate may be fastened to the base by screws 86 which pass through the base and are screwed into the side portions 19. The cover plate may however be secured by any other suitable means.

The gun may be secured to the back of the wearers hand by any suitable means. One such means is sho-wn in Fig. 1. The base i2 is provided with a series of holes 5l, and a glove 32 or other hand covering is worn on the hand. The

gun is secured to the back of the glove by a,

thong S33 of any suitable material which passes through the back of the glove and through the holes Si. In a similar manner, the gun may be secured to the glove by means of rivets or small machine screws passing through the holes 82. If this method of securing the gun to the wearers hand is used. the glove may be merely a skeleton glove without fingers if desired. It is to be undei-stood that any other suitable means to fasten the glove to the back of the hand may be used.
