' AUTOMATIC GUN.

To all whom it may concern:

Be it known that I, CLARK A. NEWMAN, a citizen of the United Long Island City, in the borough of Queens, of New York, county of Queens, and

State of New York, have invented certain new and useful Improvements in Automatic Guns, of which the following is a specifica construction, eachpossesses its tion, companying drawings, thereof.

My invention relates to automaticguns and more .parti cu1arly to a light weight, rapid fire gun, capable of delivering a number of bullets in rapid succession, or a plureference being had therein to the acwhich form a part raiity of bullets substantially simultaneously.

In a gun made in accordance with my invention, I employ a plurality of automatic magazine pistols, which may be of any desired. standard 'design and construction, said pistols being so mounted in a suitable stock as to be capable of being aimed as a unit, and fired either in rapid succession, orsubstantially simultaneously, by a single trigger mechanism carried by the themselves being of standard design and own shell ejector mechanism, safety device, mechanism, my invention relating more particularly to the manner of mounting andassociating said pistols so as to place all of them under mechanism.

A gun made in accordance with ny invention, may have associated therein any the control of a single trigger desired number or caliber of pistols, accord- .its entirety, 4O

ing to the desired weight of the weapon in or of the bullets discharged therefrom with a single actuation of the trigger.

I have demonstrated that a gun capable of discharging twenty-four shots in rapid succession,-may be so constructed as to weigh from seven to seven and one-half pounds, and that such a weapon maybe effectively used at a range of from four to five hundred yards, direct fire. It is sufficiently compact to be readily carried as a part of the standard equipment of the user, and may be conveniently fired either from the shoulder or from the hip, the mass of the weight being so positioned as to permit steadiness in the aiming of the weapon.

States, residing at stock. Theplstols and firing the trigger mechanism common to all of said pistols, with a safety device which may be used to prevent the accidental discharge of the gun. To include a further factor of safety in the fire arm, I inclose the trigger mechanisms of all the pistols in a casing, which also serves as a hand hold for steady-.

ing the gun in aiming.

A further object of the invention is to provide a light, rapid-fire gun which may be q}1l1ickly produced 1n quantities, by reason of t e utilization of pistols of standard type and construction, associated by means of a support composed offew parts, and of a design which will permit the rapid assembling of the pistols therein.

The invention consists primarily in an automatic gun embodying: therein a gun stock, a frame carried thereby, a plurality of automaticmagazine pistols mounted in said frame, a trigger mechanism carried by Patented June 24, 1919.

Application fil ed. May 1a, 1912. Serial No. 234,915.

said stock, and connections between said trigger mechanism and the triggers of said pistols respectively; and in such other novel features of construction and combination of parts as are hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

Referring to the drawings Figure 1 is a view, partly in elevation and partly in section of an automatic gun em- Joodying my invention Fi 2 is a plan view thereof with the 1 pisgo s removed from the gun stock frame; an Fig. 3 is a detailed view. of the connections between the main trigger and the triggers of the several pistols.

Like letters refer to like parts throughout the several views.

In the embodiment of my invention shown in the drawings, a indicates an ordinary gun stock having the usual pistol grip 1). his stock is made of any light material such as a hollow aluminum casting, or if desired, an ordinary wood stock may be \used. Carried by the stock a is a frame consisting of an end plate 0 adapted to conform to the rear portions of the pistol butts, said end plate having a plurality of forwardly extending partitions 01, each having a depression 11' therein, to facilitate access to the cocking and safety mechanisms of. the pistol;

In the accompanying illustrated a gun adapted to be formed of three automatic pistols A, mounted in relation to the plate 0 and the partitions 01, although the number of such pistols may be increased as desired, the design of said frame being such, preferably, as to locate the centralpistol in axial alinement with the stock, so as to permit the use of the sights upon this pistol in aiming the gun.v To hold the pistols in the proper relation to the plate a and the partitions d, I provide a lag screw e extending from side to side through the depending portions 03 of said partitions d, and engaging the butts of the end pistols, so as to hold them rigidly in place against the partitions (Z. Said lag screw takes the place of the screw ordinarily used for holding the grip plates upon the pistol butt. 7

en I employ a metal stock, said frame is formed integrally with the stock, but if a wood stock be used, it is necessary to secure said frame to said stock in any. desired manner, involving merely mechanical skill, and

forming no part ofmy present invention.

The back plate 0 .will position the pistols A, so that the trigger A ofeach pistol will of the other pistols carried by the frame.

Slidably mounted in one of. the depending portions; (Z is a connecting rod f having rigidly-connected therewith a pull bar 9 extending transversely ofthe frame, slightly in advance of the varioustriggers A, said bar extending through the trigger guards A of the several pistols. To. permit the consecutive firing of "the pistols, or their firing substantially simultaneously, I provide the bar g with the leaf springs 9 9 and 9 adapted to respectively engage the trigger A of a pistol, said springs having different tensions. The connecting rod f has an offsetportion f projecting into the gun stock, said portion being extended downthe proper o wardly at an angle so as to be brought into perative relation to the' trigger mechanism.

Inclosing the various trigger guards A and bearing against the forward edges of the pistol butts, and of the depending portions 03 of the partitions d, 'is a casing h secured in position by tie bolts 71., projecting through the portions andheld in place by nuts k disposed rearwardly of the plate c. The end of the rod 7 is reducedand screw-threaded, as shown, the pull bar 9,

being secured to said rod by the thumb nut f By this construction the casing it may 'be quickly removed to permit access to the bar 9, and said bar may be removed from the rod f to facilitate the removal ofthe,

pistols from the frame for purposes of repair, and the re-assembly of said pistols in the structure.

Acting upon the end f of the rod f is a between the projections i. the stem of said trigger, j, having an opening therein. stradin substantial alinement With the triggers ately positioned in relatign aid cam by plate It held in place by the trigger guard is, which is removably secured to the f gun stock a. v

The pistol shown in the accompanying drawings, is of the breech-loading, sliding breech-block magazine, recoil operated ejector type, provided with a safety lever m of the usual construction, so that any pistol incorporated in the may be set at safety by means of the leve m thereof. I provide,

dling a reduced portion f of the extension The trigger passes through a slotted however, in addition to this safety device, a

safety device operative upon the trigger mechanism common to all of the pistols,

so that all of .the guns may be cooked, ready for instant use, and the safe ty device of the trigger 2' be so set as toprevent the accidental discharge thereof.

This safety mechanism in the form of the inventionshown, comprises a cam n pivoted to the forked arm 0, carried by the plate 0',

which plate also carries the lugs 11'. Acting upon the cam n is a pawl 32 which is accubeing passedthrough a slot in the trigger stem j. Said pawl is pivoted to a slide q having an operating thumb piece 9' slidably mounted upon the plateo, said slide 9 pass-- ing through a slot in said plate. Acting the pistol butts are removed and one pistol inserted between the partitions d and anothe pistol inserted on the opposite side of each of said partitions. One grip is then as weight ofthe v the accompanylng drawings, the grips of v applied-to each end'pistol and the'lag screw I 0 passed through the side grip of an end pistol, the .hollow frames of. the pistol butts and the depending projection d of said partitions, and secured to the grip of the pistol at the other side of the gun. thus binding the butts of the pistols firmly against the said partitions. ,;'1 he flange upon the plate a will serve to accurately "position the end pistols.

The pull bar g is then passed through the Q guards A -of the pistols A and secured to the rod f by means of the thumb. nut 7, thus positioning said bar so .as to cause the springs g, g and 9 carried thereby, to substantially engage the triggers A of the respective pistols. The casing h is then posi- 95 upon the slideg is a detent spring r carried tioned so as to'inclose all of the guards A the showing of the 9 is suflicient this casing tie bolts h which pass under, and act as ides for preventing a rotative movement ofthe bar '9 and the rod f. The stresses applied to the casing h by the tie bolts h, will tendto force the butts of the'pistols firmly against the back plate 0 and thus hold them firmly in relation to the stock. a. It will be observed that the safety device operative upon the trigger i, is carried by the plate 0 in its entirety, and that the trigger mechanism is carried by the plate so that these mechanisms may be readily assembled in the gun in the proper relation.

' In loading, the magazine clips are inserted in the pistols in the usual manner.-

and the weapon is cooked by the rearward movement of the breech'slide of each pistol.

hen it is desired to fire the gun, the partitions d and the butts of the pistols, are grasped firmly in the left hand, the stock of the gun either being placed at the shoulder as with the ordinary rifle, or held firmly by the pistol grip b and fired from the hip, or any other desired position. The shortness of the pistol barrel results in the concentration of the bulk of the weight suiliciently close to the trigger z' to permit accurac in aiming.

In firing, the trigger i is pulled in a manner to impart longitudinal movement to the rod f and its ofi'set extension f, thus drawing the bar 9 toward the various triggers A, until the tension of the springs g g and to overcome that of the trigger springs. By having the springs g, g", and g of difierent tensions, it is possible to fire the pistols A consecutively by imparting a slow movement to the trigger, or if desired, all of the pistols may be fired simultaneously, or substantially so, by one hard pull of said trigger i. Y v v When the pistols are once cocked, the gun may be fired repeatedly until the magazine of each is emptied, experience having demonstrated' that it is possible to discharge twenty-four shots within two and one-half seconds,'with a gun made in accordance with drawings. the magazines have been emptied, the cartridge clips may be removed therefrom and fresh clips inserted.

It is desired to point out that while twenty-four shots may be fired in a small 55,

fraction of a minute, three separate pistol barrels are used so that the tendency-of the gun .to over-heat, is reduced 'to a mmimum,

and that jamming of one pistol can not in any wise aflect the operation of the others.

Immediately upon the release of the trigger i, the various triggers A are released, the springs of said triggers A serving to restore the trigger i to normal, thus utilizing the pistol mechanism as a setting device for the said trigger being secured in position by the When all of 3 The empty shells will beejected and each pistol automatically cooked, by the pistol mechanism. This mechanism forms no part of my invention, which contemplates the use of any desired type of automatic pistol and is not limited in any way to t "at shown in the accompanying drawings. In fact the frame carried by the gun stock a may be so formed as to adapt it to any make, or caliber, of pistol.

At a range of from three to five hundred yards, it will probably be desirable to fire the pistols consecutively, but at shorter ranges, it might be desirable in order to incapacitate an opponent, to discharge all of the pistols substantially simultaneously, so as to utilize the additional weight and force of the impact to check'an advance movement instantly.

While I have referred to the instantaneous fire of all of the pistols, this is not entirely accurate, since there will be an infinitesimal dwell between shots, suflicient to avoid the development of an accumulated recoil of the gun as a whole.

If it be desired to use only one pistol, the

safety levers m of the other pistols maybe] so set as to prevent said other pistols being discharged with the actuation of the trigger If, however, it be desired to have the gun in readiness for immediate discharge, and yet set at safety, the slide 9 is'pulled back by means of the thumb piece g, the rearward movement actuating the cam n in a manner to interpose it in the path of the extension f, to prevent the actuation of the trigger a and 1 By using a floatmg lever stem the assembling of the gun'is very much simplified.

The location of the thumb piece 9 makes it readily accessible to the thumb of the right hand. It will be observed that the trigger i and its appurtenances, composebut few parts, so associated and combined as to operate with certainty and not be subject to disaw rangement or breakage.

Under conditions of hard usage, it may be necessary to provide additional stay devices for the pistols A, although I have found in practice that the structure. shown holds the pistols firmly have no tendency to become sufiiciently loose in use to affect the'accuracy of aim.

It is not my intention to limit the invention to the precise details of construction shown in the accompanying drawings, it being apparent that such may be varied without departingfrom the spirit and scope of the invention.
