(FILED UNDER rim Aer or MARCH 3, 1883. easier. 1., 625.

v To all whom it may concern:

Be it known. that I, SAMUEL G. GREEN,

Lieutenant, Ordnance De artment, U. S. A.,

1 is a specification.

The invention described herein may be used by the Government,ror any of its ofli cers or employees in prosecution of work for the Government, or by any other person in the United States, without payment of any royalty thereon. a

While this invention relates generally, to firearms, it has more particular reference to machine guns, and is directly concerned with the problem of firing such gunsfrom a'distance, so that the operator may occupy a position of safety removed from proximity to the gun and fire the same with the same facility as. if he were actually beside the gun, with his finger on the trigger thereof.

p The fundamental object of the invention, therefore, is to solve the problem of firing a firearm, such as a machine gun, from a distance. i

A further object is to provide electrically controlled mechanism for firing the gun from a distance.

Another objectis to provide a form of mechanism, for accomplishing the :result to illustrate the underlying principles of the noted which will be very simple in construction, thoroughly reliable and positive in operation, and susceptible of manufacture at alow cost. The accompanying drawings disclose one of the number of possible physical embodiments of the'underlying principles of the invention.- The drawings, therefore, .show

merely an exemplary construction. Like reference characters indicate corresponding parts throughout the several views. Briefly described R Figure 1 is a view in side 'elevationjof the form of embodiment which Ihave selected invention; I

F g. 2 is a top plan view thereof;

Fig. 3 is'a' central vertical sectional view through the electro-magnet Fig. 4 is a transverse sectional view on the line 44 of Fig. 1; and

Specification of Lettersiatent. Patentedsept, 14, 1920. v

Fig. 5 is a diagram of the electrical cirtrigger is tilted upward to fire the gun. Iti will be understood that, when used with other types of machine guns having, for instance, a trigger which is pulled rearward in stead of being tilted, the mechanism shown 7 in the drawings will be slightly changed so as to adapt it for use. with such guns, such change being readily made by any skilled mechanic.- l v 1 designates the tubularportion of handleblock carrying the depending handle 2:

3 designates the trigger, which is pivoted, so that, in firing, it is tilted upward on its pivot.

4 designates a cradle or saddle, which may be made of sheet metal. The saddle carries bearings 5, 5 in which are journaled the pivot-pin 6 of a screw 7, passing throu h an opening 8 in a strap 9 carried by t e cradle 4. A wing-nut 1O threaded on the screw 7 and against the strap 9 frictionally clamps the saddle on the tubular portion 1 of the handle-block.

The cradle carries, at its rear end, depending legs 11, 11 provided with segmental angular portions 12, 12 carrying, at their ends, flanges 13, 13, through which passes a threaded bolt 14 carrying a nut 15, whereby the segmental members 12, 12 may be frictionally clamped around a tubular housin 16 for an electromagnet 17. A thread bolt 18 may pass through the legsll, 11 and be'provided with a nut 19 so that the cradle 4, at its'rear end, may-' be contracted to frictionally bind the same on the tubular member 1 of the handle-block. The housing 16 threaded caps or covers 20, 20 closing the ends of the housing. The top cover carries the binding posts 21, 21 for the terminals of electrical conductors 22, 22 of the electric circuit, shown in Fig. 5.

. .Fulcrumed on the pin 23 carried by the bracket 24'supported from the saddle 4 is a bell crank lever 25, the shorter arm 26 of which is pivoted on a pin 27 carried by a trigger-engaging member 28, which is bent at its lower end, as shown at 29, so as to extend beneath the trigger 3, the end of said bent portion being turned upward to provide the upstanding member 30. Preferably, a plate 31 is disposed on the bent portion 29 so as to extend transversely thereof, and the ends of this plate are bent upward, as shown at 32, 32. The lower end of the trigger 3 is thus inclosed on all sides by the lower end of the member 28 and the plate 32. The free end of the longer arm of the lever 25 is bifurcated, as shown at 33, to provide ears 34, 34 embracing the upper end of the link 35 pivoted at its lower end, as shown at 36, to the armature 37 of the magnet. A pivot-pin 38 passes through the ears 34, 34 and through the upper end of the link 35. Between the fulcrum point of the lever 25 and the rear end thereof is a coil spring 39, bearing, atone end, against the under surface of the lever 25 and at its other end, against the top of the saddle 4.

The spring normally maintains the lever and armature in raised posltion, as 15 obvious.

In operation, when the switch is moved I to close the circuit, the electro-magnet 17 will be energized, thereby attracting theseries, so that all of the machine guns in the battery may be fired simultansously by one operator through the operation of a single switch.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination with a firearm, of a saddle adapted to be secured thereto, an electro-magnet supported by said saddle and having an armature, a trigger-engaging member, a lever for moving said triggerengaging member and actuated by the armature of said magnet, and an electric circuit including said magnet. Y

2. The combination with a firearm, of a saddle adapted to be secured thereto and having .complemental segmental members, an electro magnet having an armature and provided with a housing embraced by said segmental members, a trigger-engaging member, a lever for moving said trigger-engaging membr connected to the armature, and an electric circuit including said magnet.

3. The combination with a firearm, of a saddle, means for frictionally securing the saddle to the firearm, an electro-magnet having an armature andv provided with a housing, means for frictionally securingv said housing to saidsaddle, atrigger-engaging member, a lever for moving said triggerengaging member and actuated by the armature of said magnet, and an electric circuit including said magnet.
