I PLANMRAPH (IO-,WASHINGTON D c UNITED STATES PATENT @FFTQE FREDERICK HARTNEY, 0F HIGGINSVTLLE, MISSOURI.

SAFETY FIRING ATTACHMENT FOR BREECI-I-LOADING RIFLES.

T 0 all whom it may concern Be it known that I, F REDERIGK I-IARTNEY, a citizen of the United States, and a resident of Higginsville, in the county of Lafayette and State of Missouri, have invented a new and Improved Safety Firing Attachment for Breech-Loading Rifles, of which the following is a full, clear, and exact description.

The invention relates to breech-loading rifles for sea coast defense and mounted on disappearing carriages.

The object of the invention is to provide a new and improved safety firing attachment for breech-loading rifles, arranged to prevent firing of the loaded gun until the latter is raised to firing position, thus preventing premature discharge of the gun into the protecting parapet.

In order to accomplish the desired result, use is made of a safety device arranged to lock the firing leaf in' position, not only when the breech block is in any other position than closed and locked, but also in any position of the rifle except when the latter is elevated above the parapet and truly ready to be fired.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a rear end view of a disappearing breech-loading rifle provided with the improvement, the rifle being in loading position with the breech block closed; Fig. 2 is a side elevation of the same; Fig. 3 is an enlarged rear end view of the connection between the safety bar and the actuating bar for the safety bar; and Fig. 4 is an in verted sectional plan view of the same on the line 44 of Fig. 3.

The barrel A of the gun is mounted by trunnions B on the swinging side arms C of a disappearing carriage of the usual construction, to permit of moving 'the gun into depressed position for loading, or elevated position for firing. The breech block D is of the usual construction and is manipulated by suitable mechanism under the control of an operator manipulating the crank arm E, so that the breech block D is secured in or out of position in the breech plate A and moves onto the tray F for supporting the breech block D in an open position.

Specification of Letters Patent.

Application filed July 25, 1911.

Patented June 18, 1912.

Serial No. 640,415.

It is understood that the mechanism for operating the breech block D may be of any approved construction, and as such a mechanism forms no part of my invention it is not deemed necessary to further describe the same. breech block D may also be of any approved construction, and hence it is not deemed necessary to describe the same in detail, it being suflicientto state that the firing mechanism is provided with the usual firing leaf G adapted to be locked against being actuated by a safety device, consisting of a 'safety slide mounted to slide in a suitable bearing H arranged on the outer face of the breech block D. The slide H is pro vided with a pin H extending in a segmental slot A formed in the breech plate A, the said pin H engaging the slot A at the time the breech block D is in closed position in the breech. The outer end of the slide H terminates in a hook H adapted to engage a pin I on a slide I mounted to slide in a guideway A formed in the face of the breech plate A, and the said slide I is preferably flush with the face of the breech plate A and is held in place by a covering plate I attached to the breech plate A. The outer end of the slide I is provided with a pin I engaging an elongated slot J in the arm J of a lever having a shaft J journaled in suitable bearings K and K arranged on one side of the barrel A, as plainly indicated in Fig. 2. The lever arm J on the forward end of the shaft J is provided with a pin or a lug J adapted to be engaged by a cam L attached to the corresponding arm C of the disappearing carriage, it being understood that thesaid cam L is out of engagement with the lug J*, at the time the gun is in a depressed position, and when the gun is elevated and moves into firing position then the cam L engages the lug J and thus imparts a swinging motion to the lever consisting of the arms J shaft J and arm J, whereby an outward sliding movement is given to the slide 1, which by the pin 1 engaging the hook H causes an outward. sliding movement of the slide H, whereby the firing leaf Gr is unlocked or released, thus permitting of firing the gun in the usual manner.

It is understood that by the arrangement described, the gun cannot be fired when in depressed or loading position, and only whenthe gun moves into the final elevated The firing mechanism for the position for firing then the firing leaf G is released to permit of firing the gun.

From the foregoing it will be seen that a premature discharge of the gun into the protecting parapet is not liable to take place.

The shaft J is pressed on by a spring N so as to return the lever and with it the slides I and H to previous position when depressing the gun into loading position.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. In a safety firing attachment for a breech loading disappearing gun, a carriage on which the gun is mounted, a movable member mounted on the breech block of the gun for holding the firing mechanism thereof against operation, a lever mounted on the gun, means operated by the lever and connected with the movable member when the breech block is in closed posit-ion, and means for operating the lever from the carriage at the time the gun is elevated in firing position.

2.
