(Cl. 42-94) This invention relates to guns of the class adapted for mounting on the forearm and for shooting when thus mounted.
There are many instances in which armed guards, police officers, armored car operators and military personnel are under the necessity of working with their hands in the performance of various tasks where-an instantaneous need may arise for use of a gun. Such instances are particularly common in warfare, in the case of personnel not primarily rifle men, such as raiders, vehicle operators, artil lery men, bazooka and mortar men, technical personnel, ofiicers, etc. These classes of individuals have many tasks to perform requiring the full use of both hands, yet they often work sufficiently close to the front to be subject to enemy surprise and hence require the instant use of a.
personal weapon of defense. In these situations the guns which are currently available, including holster weapons, carbines and sub-machine guns, are unsatisfactory because of the delay experienced in mounting and firing them. 1 Accordingly it is the general object of the present invention to provide a gun which may be carried on'the forearm and fired instantaneously while thus carried, without materially hampering the use of the hands and arms of the wearer for other tasks. 1
The advantages of the forearm gun provided by the present invention thus include the following:
(1) It can be worn comfortably over long periods of. time without cutting off the circulation, irritating the' nerves, or pinching the skin.
(2) It may be mounted upon and demounted fromthe forearm substantially instantaneously.
(3) It is instantaneously and automatically adjustable for use upon forearms of varying lengths and thickness.
(4) It is mountable readily upon a belt worn about the waist when it is not urgently needed.
(5) It may be fired when mounted on the forearm, on the belt, or when it-is held in the hands.
(6) When mounted on the forearm it is stable and may be sighted and fired accurately.
(7) It is mounted on the forearm in such a manner that its recoil is not offensive or a problem.

Generally stated, the forearm gun of this invention comprises a gun body of suitable dimensions for mounting on the forearm-means for releasably securing the rear terminal portion of the gun body to the forearm and about the waist when this is desired; for accommodating 1 upper arm, and means for releasably securing the forward terminal portion of the gun body to the hand. Means also are provided for mounting the gun on a belt worn guns of various lengths on the mounting means on the arm and on the belt; and for triggering the gun positively The gun The general character of the forearm gun described herein and of the mount employed for it is apparent from Figs. 1, 2 and 3. The gun may be of any type having dimensions suitable for mounting on the forearm. Thus it may be specially designed, or it may comprise a modified or unmodified standard gun type such as a .45 caliber hand gun, or particularly, a modi: fied U.S. Army 'Ml or M-2 carbine.
A carbine type gun is shown'in the illustration. As shown, the stock has' been removed and the barrel shortened. Otherwise it includes the usual mechanical elements associated with guns of this class including bolt, slide and cocking hook assembly 22, cartridge clip 24, trigger 25, and muzzle 26.
' The gun mounting assembly The gun mounting and firing elements of the herein described assembly may be attached directly to the gun body, particularly where the latter is designed and dimensioned especially for use as a forearm gun. However, where a standard carbine or other gun is adapted for such use, it may be mounted in a casing indicated generally at to shield the mechanism and hot barrel. This casing conforms generally to the contour of the gun and is provided with suitable openings for loading and firing the gun.
Means are provided for mounting the gun or the gun casing, as the case may be, on the forearm of the user The means employed for this purpose comprise broadly a. harnessfor mounting the rear terminal portion of the gun on the forearm and upper arm, and a grip for mounting the muzzle portion of the gun on the hand. A rear sight 32 then is mounted in an appropriate po' sition on the upper surface of the casing for use in conjunction with front sight 33. Also, a perforated bracket 34 extends laterally from the side of the casing for mounting the gun on the belt as will be explained hereinafter.
For mounting the rear terminal portion of the gun on the forearm there is provided, on the upper inner side edge of the casing, a hook 36 having in its upper under surface a pair of spaced apart projections or dogs 38, 40 (Figs. 15-17). This hook cooperates with a clip indicated generally at 42 and stationed on the lower insfde, edge of the casing preferably in substantial vertical alignment with hook 36.
Although clip 42 may be variously constructed, in the illustrated form it comprises a shank portion 44 and a clip or latch portion 46. The shank portIon is pivotally attached to an extension of casing 30 by means of pin 48. A resilient means such as spring 50 is provided for maintaining the clip normally in its advanced, operative position.
Hook 36 and clip 42 are designed and dimensioned for attachment to a harness assembly by means of which the rear terminal portion of the gun is mounted on and supported by the forearm and upper arm of the user. This assembly includes a first plate 52 having along its upper edge a plurality of serrations 54, the spacing of which corresponds to the spacing between projections 38, 40 on clip 36. The length of the serrated surface of the plate is sufiicient to enable mounting of gun bodies of varying length on forearms of varying length.
The forward portion of plate 52 carries a laterally extending second plate 56. This plate preferably is arcuate in contour to conform to the contour of the upper forearm surface which it engages. It may be padded with sheepskin or other suitable material for comfort and safety. It is connectible to an adjustable strap 58, the lower end of which is affixed to the lower edge portion of plate 52, and the upper end of which is provided with a snap fastener 60 for releasable attachment to plate 56.
Plate 52 is articulated with a third plate 62 by means of a pin 64 which penetrates overlapped extensions of the two plates. It is to be noted particularly that plates 52 and 62 are proportioned'and positioned in such a manner that pin 64 is aligned with the elbow joint. Accordingly as the forearm is raised and lowered in a normal manner, plate 52'follows this motion without impeding or hindering it.
Plate 62 is generally arcuatc in contour to conform to the upper surface of the upper arm. A cooperating fourth plate 66 is arcuate to conform to the contour of the lower surface of the upper arm. The two plates are interconnected by suitable means such as adjustable straps 68, 70 interconnecting one pair of opposite side edges of the two plates, and adjustable straps 72, 74- interconnecting the other pair of opposite side edges of the plates. Suitable means such as snap fasteners 76, 78 may be provided for releasably attaching the ends of straps '72, 74 to one or the other of the plates, preferably plate 62. Thus the supporting harness including plate 52 may be mounted on the arm easily and rapidly by the simple expedient of closing snap fasteners 60, 76 and 78.
As indicated above, the forward or muzzle portion of the gun is supported by the hand of the user. For this purpose, there is provided on the forward portion of the inner side of casing 30, or of the gun body if a. casing is. not employed, a grip assembly indicated generally at 80.
The construction of a suitable form of such an assembly is illustrated particularly in Figs. 5 and 6. Thus it may comprise a rigid, yoke-shaped, hollow, horizontal cross piece 82, one end of which is attached to the upper edge of the forward portion of casing 39. The outer edge of cross piece 82 connects with a vertical bracket 84 which also is hollow. It carries a housing 86 which preferably is substantially square in cross section and which contains the trigger actuating mechanism, as will be explained more fully below.
Attached to the lower end of bracket 84, or of housing 86, is a flexible link member indicated generally by the numeral 88 and including preferably a flexible metal strap. 90 (Fig. 7) contained in a flexible tube 92.
The lower end of strap 90 is attached through a pin 94 to the lower outer end of a rigid cross piece 96. The upper end of this cross piece is attached to or integral with the lower inside edge of the forward portion of casing 30 or to the lower front portion of the gun body as the case may be.
An adjustable strap 97 interconnects the central portion of upper cross piece 82 and the lower portion of flexible connector 88. Thus, as is particularly apparent in Figs. 1 and 5, strap 97 forms with bracket 84 and connector 88 a loop through which the fingers and the for- Ward portion of the palm of the hand may be inserted. Since this opening is adjustable, the mount is adaptable for use by persons having different sized hands, and also by persons wearing heavy gloves in cold weather.
From the foregoing it will be evident that the herein described forearm gun may readily be mounted on the arm. This is accomplished simply by placing the fingers of the hand through the opening formed by strap 97, bracket 84 and connector 88 until a comfortable operating position is attained. The rearward portion of the gun then is placed adjacent plate 52 on the arm harness. Thereupon book 36 may be slipped over serrated edge 54 of the plate, where it automatically will engage appropriate ones of the serrations. This makes possible automatic and immediate adjustment of the assembly for use by personshaving forearms of different lengths.
Clip 42 then may be snapped under the lower edge of plate 52. This completes the mounting operation in circumstances wherein it is desired to have the gun in readiness for immediate use.
Alternate mounting means are provided, however, for mounting the gun at the waist of the wearer where the need for use is not so urgent. A suitable belt mounting means for this purpose is illustrated in Figs. 1, 2, 15 and 16.
It includes an adjustable belt 98 to the front of which is attached an elongated plate 100. Attached to plate 100, or formed integrally therewith, is a second plate 102 having a serrated edge 104. The dimensions of these serrations are identical with those of the serrations 54 on plate 52. Hence they are adapted for the reception of projections 38, 40 on hook 36 of the gun casing.
Also provided on plate 100 is a belt hook or dog 106. This member is dimensioned for-reception in the opening in bracket 34 on the gun casing referred to hereinabove. As a consequence, the front portion of the gun may be rapidly mounted on the belt by inserting belt hook 106 in the opening in bracket 34. The rear portion of the gun then may be connected to the plate by slipping book 36 over the serrations 104, on the top edge of plate 102, and snapping clip 42 over the bottom'edge thereof.
When the gun is thus mounted at the waist, it may be carried comfortably and securely for long periods. However, it is ready for immediate attachment to the forearm, or may even be aimed With an appropriate swinging motion of the body and fired from the waist, using the left hand to pull the trigger.
The triggering mechanism' As is apparent from a consideration of Figs. 6-14, the gun trigger preferably is actuated by means of the right thumb. This makes possible firing the gun even though heavy mittens or gloves are being worn. It also minimizes fiinching of the marksman when the gun is fired.
Accordingly the trigger actuating mechanism is mounted in part in housing 86 which, as has been indicated above, is connected to bracket 84 of grip 80. As will be seen from Figs. '1 and 3, this places the trigger actuator directly adjacent the thumb when the fingers of the hand are inserted through the grip.
In the illustrated form, the trigger actuator comprises a button 110 having thereon a laterally extending wing 112. The latter element serves as a safety for the gun.
For this purpose the upper surface ofv housing 86 is formed with a cut away portion 114 and a communicating vertical slot 116.
When button 110 is in the position of Fig. 7, wing 112 abuts against the edge of cut away portion 114 of housing 86. Accordingly the button can not be depressed and the gun is in locked or safety position. However, when button 110 is rotated through 90 and assumes the position of Fig. 8, wing 112 registers with slot 116. The button then can be depressed, and the gun will be in firing position.
To make the rotary movement of button 110 between its safety and firing positions more positive, and to insure that it will not stop at an intermediate position, positioning means illustrated particularly in'Fig. 9 are provided. For this purpose the shank of button 110 contains a central transverse opening 120. A compression spring 122 is seated in this opening. Balls 124, 126 are seated in the terminal portions of the opening in resilient contact with the ends of the spring.
Since housing 86 is square in cross section, it will be evident that when wing 112 is in the safety position of Fig. 7, balls 124, 126 will nest partly in opening 120 through the button and partly in the corners of the bolls.
122 will force them out into the other opposed pair of corners of the housing. This positions the safety very accurately in on and off positions.
Button is connected to a plunger 130. Unlike the button, which is circular in cross section, plunger is square in cross section and is in sliding engagement with the inner side walls of housing 86. Itis releasably connected to the lower end of the button by interengaging a flange 132 on the latter with a correspondingly dimensioned slot in the head of the plunger. a
Vertical sliding movement of plunger 130 is restricted by means of a spring pressed stop 134. This stop is formed with a projecting head 136 and is mounted in a recess 138 in a side wall .of the plunger. The stop is backed up by a compression spring 140 which normally urges it outwardly with head 136 extending through a slot 141 of restricted dimensions in housing 86. As a result, button 110 and plunger 130 can be moved vertically to an extent determined by the dimensions of slot 141. Also, if it is desired to remove the plunger and button from the housing, the head of the stop may be depressed until it clears the inner side wall of the housing. Thereafter the plunger and button may be easily extracted.
The lower surface 142 of plunger 130 is angled as is evident particularly in Figs. 7 and 8. This makes possible exertion of a camming action which can be'used to actuate the gun trigger. Accordingly there is provided a cam 144 having a slope corresponding to that of surface 142 of the plunger. A roller 146 rotatably mounted on a bail 148, or other suitable means, is interposed be.-
tween plunger surface 142 and cam 144. As a result,
when the plunger is depressed, the thrust is conveyed ment of lubrication, from the position of Fig. 7 to the position of Fig. 8. If a foreign substance, such as mud or snow, is introduced, the roller removes the obstruction in one stroke without roughening any of the surfaces, as might be the case with a metal-to-metal sliding cam. The bail does not function as a hub for the roller, but; merely to loosely retain it in approximately correct position, from which it might be thrust by dirt or vibration. Movement of the plunger and cam is facilitated by antifriction means comprising a roller 150 rotatably attached by means of bail 152 to plunger 130. This roller is mounted in a recessed portion of the side wall of the plunger whichis opposite the cam surface. Hence as the plunger is depressed, the side thrust of the operation is exerted against roller 150 which moves to the position of Fig. 8. This makes possible smooth operation of the plunger; eliminates sticking; and eliminates the necessity of lubrication.
. The motion of cam 144 is translated into the angular motion of a vertically mounted lever 154 (Fig. 5). The upper end of this lever is connected through collar 158 to a shaft 156 which is journaled in opposite end walls of hollow cross is connected through collar 160 to a vertically arranged lever 162. The lower end of this lever in turn is connected through clevis member 164 to a tubular link member 166 which extends substantially the length of the gun body and is mounted for longitudinal movement. Means are provided for interconnecting tubular link 166 with trigger 25 of the gun. Such means include means for compensating for slight variations in trigger dilferent guns which may be integrated with the assembly. This construction is illustrated in Figs. 12-14.
As is apparent from these views, link 166 extends into a longitudinal recess 172 centrally located in a slide member 174. The latter member is inthe form of a T, the cross bar 176 of which is in sliding engagement with a side wall of casing 30.
The other segment 178 of the Tshaped slide extendsmto the interior ofthe casing.
Its terminal portion is piece 82. The inner end of shaft 156 aermoa formed with a jaw 180 which releasably receives the end of trigger 25. Accordingly, when link 166 is moved to the leftas viewed in Fig. 12, it moves the trigger to firing position. However, when pressure is released on button 110, the trigger spring of the gun forces the link, and the button, back to their normal positions.
A means which may be employed for adjusting the connection between slide 174 and link 166 is illustrated in Fig. 14. To achieve the desired adjustment, a screw 182 is threaded into the end of the recess 172 opposite the end of link 166. The head of the screw is aligned with an opening 184 in casing 30. This makes possible turning the screw with a screw driver until it just engages the end of the link, thereby insuring that depression of button 110 will instantaneously move the trigger and fire the gun.
An alternate construction for the trigger actuating means is illustrated in Fig. 18. In this construction a hand grip 190 corresponding in function to hand grip 80 of the previously described embodiment is mounted on the forward portion of casing 30. A housing 192 is rigidly mounted on the outer vertical face of the grip. A button 194 provided with a locking wing 196 is mounted for vertical reciprocation in the housing in a manner analogous to that in which button 110 is mounted in housing 86. The movement of button 194 is limited by pin 198.
A flexible cable 200 is connected to the lower portion of button 194. It passes through a first tube 202 which is of substantial construction and part of the hand grip. It then passes through a flexible tube 204 rearwardly where it is connected to the trigger in the manner described above in connection with slide 174. Accordingly, depression of button 194 trips the trigger, but against the force exerted by the trigger spring. Then when pressure is released on the button, the trigger spring returns it to its elevated position.
Operation The operation of the herein described forearm gun is as. follows:
First, forearm plate 52 is mounted on the forearm by means of strap 58 and snap fastener 60. Then upper arm plates 62, 66 are put in place and fastened by means of straps 72, 74 and fasteners 76, 78. The position of these three plates relative to the arm is such that pin 64 which interconnects plates 52, 62 is in direct alignment with the elbow joint. As a result, the forearm may be moved in normal manner without binding or restriction.
Next, belt 98 is placed about the waist with plates 100 and 102 toward the front.
To mount the gun on the forearm, it is grasped in the left hand and swung out over the right forearm and the fingers of the right hand slipped through grip 80 between strap 97 and connector 88. This places the right thumb in a natural position adjacent or above trigger button 110.
Next, hook 36 on the rear portion of the gun casing is slipped over the upper edge of plate 52 whereupon dogs 38, 40 on the underside of the hook engage the adjacent serrations 54. on the upper edge of the plate. In this manner adjustment is made automatically for variations due to use of gloves or heavy clothing, or for individual variation of forearm length. After the dogs 38, 40 engage serrations 54, the gun is released by the left hand and its weight causes latch portion 46 of clip 42 to close over the lower edge of plate 52, thus locking the gun securely to the arm.
The gun is now in the position of Fig. 1. It may be fired by pointing from the hip, or sight-aimed in the manner indicated in Fig. 3.
Before shooting, the safety catch comprising wing 112 on button 110. is moved from the position of Fig. 7 to that of Fig. 8. This movement is accompanied by a 90 shift in the position of balls124, 126 (Fig. 9) from the.
indicated position to that in which they occupy the other corners formed by the side walls of housing 86. This makes positive the adjustment of the safety between on and off positions. 1
Button 110, may be depressed when the safety is in its.
oif position. This in turri depresses plungerto theposition of Fig. 8, the lower limit of depression being determined, by the engagement of spring pressed stop 136 with the bottom edge of slot 141. As plunger 130 moves downwardly it moves cam 144 to the right as viewed in Figs. 7 and 8, the interposed roller 146 facilitating this motion. Also, the action of roller 150 interposed between the side walls of plunger 130 and housing 86 takes the side thrust exerted by this motion so that the movement of the plunger is free and substantially frictionless, even without. thebenefit of lubrication. The sideways movement of cam 144 induces angular movement in lever 154 to which the cam is connected. This in turn moves lever arm 162 in cming 30 (Fig. 5) in the same direction. As a result, link 166 is moved to the left as viewed in Fig. 12. This causes slide 174 to move, to the left and accordingly actuatcs trigger 25 against the force exerted by the trigger spring of the gun. This fires the gun, after which the trigger spring forces link 166 and button 110 back to their former positions.
When the gun is fired, recoil is. transmitted painlessly to the arm by the articulated and padded arm plates. These are so shaped as to bridge all major blood vessels and nerves and to impose the weight substantially on the skeleton of the wearer, rather than upon flesh and muscles. As a result the weapon can be carried on the arm for long periods with little fatigue or discomfort, permitting free use of both hands for practically any task, yet ready for instantaneous firing should need arise. In addition, desirable effects noted from experimental firing include remarkable freedom from fiinching while using the thumb trigger, as complred to the finger trigger of a conventional gun; and a feeling of great comfort and stability in aiming, either from the hip or by means of the sights, due to the fact that the major part of the weight of the gun and ammunition is supported near the elbow, rather than extending beyond the end of the hand, as with a conventional pistol.
Where the need for use. of the gun is not likely to be acute, it may be mounted at the waist in the manner indicated in Fig. 2. In this position, belt hook 106 is inserted in the perforation in bracket 34 on the gun casing. Hook 36 on the latter then is slipped over the serrated portion of plate 102 whereupon dogs 38, 40 are instantaneously received in the adjacent ones of serrations 104. Clip 42 then may be snapped under the lower edge of the plate to anchor the gun on the belt.
If need should arise to shoot the gun while it is being worn at the waist, this may be done without the necessity of removing it from the belt. Thus the body may be turned to aim the gun and button 110 depressed with the thumb of the left hand. Also, if desired or necessary, the gun may be fired while being held in the hand, somewhat in the fashion of shooting a conventional rifle, except that triggering is, performed with the left thumb.
