MEANS For: HOLDING THE roan-nuns or FIREARMS IN rosrrron.

' Application filed March 28, 1913.

To all whom it may concern V Be it known that I, ARTHUR P. CURTIS, of Fulton, in the county of ()swegoand State of New York, have invented a new and useful Means for Holding the Fore-Ends of Firearms in Position, of which the following is a specification.

This invention relates to firearms and has for its object particularly simple and efficient means for holding the removable foreend in position; and the invention consists in the combinations and constructions hereinafter set forth and claimed.

In describingthis invention reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure 1 is. a side elevation, partly broken away, of a firearm embodying my invention.

Fig. 2 is a longitudinal sectional View through the fore-end and contiguous parts of the firearm. v

Fig. 3 is a horizontal fragmentary sectional view through the fore-end showing the catch in plan.

Fig. 4 is an enlargedtransverse sectional fragmentary view through the loop lug and fore-end iron, the wood portion of the foreend being removed.

Fig. 5 is a fragmentary plan view of the fore-end iron showing the manually controlled catch in dotted lines in itsspread position. Y

Fig. 6 is a perspective view of the manually controlled catch.

This gun comprises a removable fore-end, and means for holding the fore-end in position, said means including a manually controlled or operable catch element.

I have here illustrated my invention as embodied in a break-down'shot gun.

' 1 is the frame, 2 the barrel and 3 the removable foreend, the barrel having the usual loop lug 4 which extends into a slot 5 in the fore-end iron 6.

The means for securing the fore-end in positioncomprises the usual movable spring catch 7 pivoted at 8 to the fore-end iron which spring 7 is held from abnormal displacement 'by a spring 9-, and the manually controlled catch also 'coacts with the lug 4. The spring catch is as usual in the form of a loop.

10 is the manually operable catch element, said element having a spring pressed portion Specification of Letters Patent.

movable laterally into and out of interlock- :ing engagement With' the side face of the loop lug 4 and as here shown the catch element is formed double, that is U-shape, and includes branches or arms, having heads or jaws 11 on opposite sides of the loop lug '4 and movable laterally into and out of grooves 12 formed in opposite sides of the loop lug.- y

This catch element 10 is formed of spring metal and the branches thereof are sprung by their own resiliency into the grooves 12; and the jaws or heads 11 thereof are sprung out ofthe grooves by surfaces associated with the fore-end iron and the branches of said element 10, and as here shown the foreend is formed with forwardly facing'converging surfaces 13 which coact with diverging surfaces 14 at the ends of the heads or jaws 11, when relative movement of the surfaces 13 and the element 10 is effected.

The, jaws 11 are also formed at their op posing edges with beveled faces 15 facing upwardly and. arranged to engage the lower outer edges of the lug 4 when the fore-end is being swung into its normal position about the axis of the face 16 at the rear end of the fore-end, as will be understood by those skilled in the art, these beveled faces 1.5 causing the jaws 11 to spread apart and have a ratcheting action into the grooves 12 of the lug 4 so that manipulation of the element 10is not necessary when the fore-end is being placed in position onthe barrel.

In thisembodiment of my invention the .catch element 10 is slidable lengthwise of the foreend and the operating member is connected to the element 10, a

The element 10 is arranged in a recess or slot 17 formed in the front end portion of the fore-end iron, this recess or slot opening into the slot 5 for the loop lug 4 and constituting a guideway for the member 10;

18 is the operating member for the catch element 10, said member extending lengthwise of the fore-end in a bore in the foreend wood, and having a head 19 exposed at the front end of the fore-end. The operating member consists of a rod fixed at its rear end to the catch element 10.

In the illustrated form of my invention the element 10 terminates at its front end in a lug 20 having an open ended slot 21 and the rod 18 is formed with grooves on opposite sides thereof which form a head 22, the

ILJ

grooves receiving the walls of the lug 20 on opposite sides of the open ended slot 21,

In operation, when it'is desired to remove the fore-end, the head19 is pressed rearwardly, this moving the element 10 rearwardly causing the cam surfaces 13 and 14 to spread the jaws or heads 11 apart out of engagement with the grooves 12 of the loop lug 4. The front end ofthe fore-end can then be pulled downwardly and the fore-end removed: in the usual manner.

' In replacing the fore-end the surface 16 is first placed in position at the front end -of the frame 1 and the spring 7 placed in operative relation to a shoulder 45- on the loop lug a. The fore-end is then pressed into operative position in the usual manner, the jaws 11 ratcheting into engagement with the loop lug t owing to the inclined or beveled faces 15. i.

By the use of'a manually operable catch, a relatively light spring 7 can be employed 1 so that the removal of the fore-end can be used. By'placi'ng the head of the operating accomplished with comparatively little effort and the fore-end is as firmly held in position as when the usual stifi' spring is member at the front end of'the fore-end, the

fore-end is removable by substantially the same movement of the hand in the same manner as heretofore, the finger pressing I rearwardly on the head 19 also being in position to pull downwardly on the front end of the fore-end to facilitate the removing of r the fore-end, the head 19 being beveled and checked as shown.
