ATTACHMENT FOB. FIREARMS.

Specification of Letters Patent.

Patented se t. 2, 1913.

Application filed February 14;, 1913. Serial No. 748,431.

To all whom, it may concern Be it known that I, LOUIS F. KUNZ, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Tmprovements in Attachments for Firearms, of which the following is a specification.

This invention relates to an attachment for pistols or revolvers, the primary object thereof being to provide a device for securing the hammer of the firearm to which it is attached positively in cocked position whenever desired.

In using a revolver, rifle, or other firearm for hunting purposes, it is often necessary to carry the firearm cocked so as to be ready for immediate use without the necessity of having to cock the same at the instant it is desired to shoot. This is undesirable in most instances, because of the danger of accidental discharge. In hunting game, such as turkeys or deer, it is necessary that the hunter should crawl through and lie quietly for hours at a time in the cold, damp underbrush. All this time the firearm should be cooked, as there is danger of the hunters fingers becoming so numb because of the cold that it is utterly impossible for him to cook the gun hurriedly when the occasion demands and is in a prone position. It should be readily apparent that it is exceedingly undesirable, in so far as accidental discharge is concerned, to maintain the firearm cocked under such conditions. By using my securing or looking attachment upon any firearm, the firearm may be carried cocked for indefinite periods of time without danger of accidental dischar e, and its usefulness in the hunting sport should be readily appreciated.

A further object of the invention is to provide a device of this character which is constructed so as to be adapted to rest securely in its operative, locking position, and yet which may be readily manipulated so as to assume an inoperative position out of the path of movement of the hammer of the firearm.

The invention consists in the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawing, in which:

Figure 1 is a side elevation of a revolver having the attachment applied thereto, the said attachment being shown in operative,

l locking position; Fig. 2 is a rear elevation ofthe same; Fig. 3 is a top plan view, the dotted lines representing the inoperative position of the locking member; and, Fig. 4: is a transverse sectional View through a portion of the revolver and the locking member, showing the means for maintaining the locking member in operative position.

In the drawing I have shown the attachment in use upon a revolver of ordinary well-known construction, but it is to be understood that the same may be employed in connection with any sort of firearm, provided its hammer is exposed.

The attachment comprises a flat body 1 constructed of resilient material, such as tempered steel, or the like. The body 1 is shown in this particular instance, as pivotally connected at its forward end to the frame top piece 2 of the revolver 3, by means of the vertically disposed pivot screw 1 which is threaded into a recess 5 provided in the said top piece. The memher 1 is thus mounted for horizontal swinging movement and is adapted to bear flat against the upperrface 6 of the top piece 1, and is provided with a depending lug 7 for engagement within a recess 8 provided in said face 6, when the locking member is in its rearwardly extending, operative position parallel to the longitudinal axis of the barrel 9 of the firearm. The lug 7 and receiv ing recess 8 have their side walls beveled so as to be substantially V-shaped, in order that the application of pressure to the memher 1 in a lateral direction will cause the lug to ride up onto the upper face 6 of the frame top piece, thus freeing the locking member and permitting lateral deflection of the same. The securing lug will, however, maintain its engagement within the said re cess so as to prevent lateral deflection of the locking member under the ordinary conditions of usage.

The locking member extends rearwardly from the frame top piece and is provided with a depending abutment 10 which is disposed in the path of movement of the hammer 11, when the locking member is in its operative position. In this position, the abutment 10 does not necessarily have to be in engagement with the hammer, but is so disposed that the hammer will strike the same, in case it is released by the accidental pulling of the trigger 12, and will in this event prevent the hammer from striking the firing pin of the revolver and will maintain the same in this locked position until it is restored to cocked position by the user. It is often desirable thatthe abutment 10 should be in spaced relation to the hammer when the latter is cooked so that accidental tripping of the hammer will be indicated by the click of its engagement with the abutment,

so that the user will be aware of this conditachment of the class described, which may be readily applied to revolvers, rifles, or other firearms, which is simple in construction, so as to be inexpensive in manufacture,

and which will be ethcient in operation. I desire to have it understood, however, that minor changes in theconstruction, which may be found desirable in practice, may be resorted to without departing from the scope of my invention.

What I claim is:

1. In a device of the class described, the combination with a firearm including a frame and a movable hammer, of a locking member pivoted to the frame for transverse swinging movement, a locking abutment depending from said member, saidabutment being adapted to be disposed in the path of movement of the hammer when the said member is swung into operative position, and means carried by said member for engagement with the frame to lock the member in its operative position.

2. In a device of the class described, the combination with a firearm including a frame and a movable hammer, of a resilient locking member p'ivotally connected to the frame, for transverse swinging movement, a locking abutment depending from said member and adapted to be positioned in the path of movement of the hammer when the said member is in its operative position, the said frame being provided with a recess, and a retaining lug provided upon said locking member for engagement within the recess when the member is in operative position.

3. In a device of the class described, the combination with a firearm including a frame and a movable hammer, of a resilient locking member pivotally onnected to the frame for transverse swinging movement, a locking abutment depending from said member and adapted to be positioned in the path of movement of the hammer when the said member is in its 0 aerative position, the said frame being provided with a recess, and a substantially V-shaped retaining lug provided upon said locking member for engagement within the recess when the. member is in operative position.

In testimony whereof I atlix my signature in presence of two witnesses.

, LOUIS F. KUNZ.
