LOUIS 1. SMITH, OF ITHACA, NEW YORK.

CARTRIDGE EXTBACTOR FOR BREAKDOWN FIREARMS.

Application filed August 27, 1925.

To all 1071 omit may concern:

Be it known that I, LOUIS P. SMITH, a citizen of the United States of America, residing at Ithaca, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Cartridge Extractors for Breakdown Firearms, of which the following is a specification.

This invention relates to improvements in cartridge extractors for break-clown firearms.

The primary object of this invention is to provide an extractor mechanism for the break-down type of firearm, either of the single or double barrel type, wherein a cartridge case will be started or drawn a short distance from the breech end of its barrel, when the gun is broken, if the cartridge has not been fired, but will be entirely extracted or thrown from the breech if it has been fired.

A further object of the invention is to provide a novel retainer mechanism for the cartridge case extracting or expelling member which will maintain the latter member inoperative when the gun is broken if the cartridge has not been fired.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 9 shows in end and side elevation a kicker cocking cam,

Figure 10 shows in side and end elevational views a kicker element, and

Figure 11 shows in side elevation and bottom plan a kicker retainer element.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 5 designates the frame portion of a break-down type of firearm which has pivoted to its fulcrum pin 6 the fore end 7 the fore end and frame being pivotally moved in respect to each other when the gun is broken.

Suitably carried by the frame 5 is a ham mer 8 having a hammer sear 9 associated therewith and employed for retaining the hammer in its cocked position. This sear 9 is operated for releasing the hammer 8 by the trigger 10. It is to be understood that the second trigger 11 is also provided with a hammer sear and a hammer of similar construction to the elements designated by the numerals 8 and 9 and that such combined mechanisms constitute a double barrel type of gun. The hammer 8 is pivoted at 12 and is provided with an ear 13 having connected thereto, by the pivot pin 14, a hammer cocking rod 15 which bears against the cooking cam 16 at its forward end. This cocking cam 16 is pivoted upon the pin 17 carried by the frame 5.

This cocking cam 16 is illustrated in detail in Fig. 7 and in operative assembly in Fig. 5 and is shown as including a heel portion 18 against which the hammer cocking rod 15 bears. The cooking cam 16 is further provided with a camming end 19, the function of which will be described in detail at a later point.

In Fig. 6 there is shown in detail an extractor cam 20 which has an aperture 21 for receiving the fulcrum pin 17 which supthe frame 5 and is curved at 23 to corre-' spond with the curvature 24 of this forward end of the frame 5 for being arranged to correspond or aline with said curvature 24.

' Formed in this curvedface '23 is a notch 25,

the function of which will be described at a later point. A camming end 26 projects from the upper portion of the extractor cam 20 and protrudes beyond the curvature 24 of the forward end of the frame 5 to be received within the cutout portion 27 of the fore end.

This cutout portion 27 has communicating therewith a cylindrically-shaped opening 28 in which is received the cylindricallyshaped stem portion 29 of the kicker cocking cam 30 which is formed with a camming end 31 against which the camming end 26 of the extractor cam 20 normally bears. This oylindrically-shaped stem portion 29 is longitudinally cutaway at 32 for receiving the movement limiting pin 33 which extends transversely of the fore end 7 and functions to limit the reciprocal movement of this kicker cocking cam 30.

The fore-end 7 in Fig. 3 is illustrated as being formed with the parallel extending slots 34 through which slidably project the stem portions 35 of two kickers 36, one of which is illustrated in detail in Fig. 10. These kickers 36 each include an operating arm or plunger 37 mounted on the stem 35 and a base block 38 having formed therein a longitudinally extending, internally screwthreaded bore 39 which is intended to receive the threaded end of the kicker rod 40 having surrounding the same the spring 41 which bears at its opposite ends against the base block 38 and the bearing bracket 42, the said bearing bracket slidably receiving the free end of therod 40.

The fore end 7 is provided with two pairs of depending arms 43, best illustrated in Fig. 2, which carry the fulcrum pin 44. Pivotally ,mounted upon this pin 44, between the said pairs of depending arms 43, is a kicker sear 45, shown in detail in Fig. 8 as including a notched end 46 and an operating end 47. The notched end 46 of the kicker sear 45 is-opera-tively associated with the lower front edge of the base blocks 38 of the kickers 36, as best illustrated in Fig. 2.

Pivoted to the fulcrum pin 44 and arranged between the respective depending arms of the pairs of arms 43 are the two kicker retainers 48, one of which is shown in detail, in Fig. 11 as including a notched end, 49 and a laterally offset upwardly and longitudinally curved operating end 50.

" The operating ends 50 of the kicker retainers 48 and the operating end 47 of the kicker sear 45 project through the end of the fore end 7 shown in elevation in Fig. 4. The kicker retainer operating ends 50 project through the openings 51, shown in Fig. 4 in elevation and in dotted lines in Fig. 2, while the kicker sear operating end 47 projects through the opening 52, shown in elevation in Fig. 4 and; in dotted lines in Fig. 2. The notched ends 49 of the kicker retainers 48 are associated with the independent kicker base blocks 38, as best illustrated in Fig. 2.

It is to be understood that the elements shown in Figs. 6, 8 and 9 are suitable for use with a double barrel gun without being duplicated and thatthe elements shown in Figs. 7, 10 and 11 must be duplicated for a double bar-rel gun structure. The functioning of the various elements just referred to, however, is exactly the same in either a single or a double barrel structure. Therefore, the functioning of one barrel will be described, and it is considered that such a description will be sufficient for illustrating the operation of either a single or double barrel gun.

It will be understood that the hammer 8 is cooked when the fore end 7 is pivoted in res ect to the frame 5 i. e. when the "un is broken. This pivotal movement of the fore end 7 will cause the cocking cam 16 to be pivoted upon its pin 6 for moving the hammer cocking rod 15 longitudinally'toward the hammer 8. thereby pivoting the hammer into its cocked position. The cooking cam 16 will then normally be positioned with its camming end out of operative relation. with the operating end 50 of its kicker retainer. WVhile the hammer 8 is in its cocked position, the gun may be broken without extracting or discharging from the breech end of the barrel the cartridge case located therewith. This is accomplished in view of the fact that the kicker retainer 48 is arranged with its notch end 49 in engagement with the lower transverse edge of the kicker base block 38 and with the cooking cam 16 out of operative relation in respect to the operating end 50 of the kicker retainer, the latter will not be disturbed and will continue to hold the kicker inoperative when the gun is broken. The kicker sear, however, will be pivoted to disengage its notched end 46 from the base block 38 of the kicker every time the gun is broken.

After the hammer '8 has been moved into its fired position, the cooking cam 16 has its cainming end 1.9 projecting into a position to underlie the operating end 50 of the kicker retainer 48. Upon. breaking the gun, with the camming end 19 projecting beyond the end of the gun frame 5, both the kicker retainer 48 and the kicker sear 45 will be will entirely release the kicker 36 and the same will be thrown longitudinally toward the gun frame 5 by the kicker spring il. This longitudinal movement of the kicker 36 will entirely extract the cartridge case from the barrel. Upon returning the gun to its normal or unbroken position, the cam ming end 26 of the extractor cam 20 will be moved into engagement with the camming surface 31 of the kicker cocking cam 30. This engagement of these two elements will cause longitudinal movement of the kicker cocking cam 30 which will bear against the base block 38 of the kicker for moving the same against the tension of the spring 41. This kicker will be moved by the kicker cocking cam 30 until the notched ends 46 and 49 of the kicker sear 45 and kicker retainer 48 will receive the lower transverse edge of the base block 38 of the kicker, when the kicker will be held in its cocked position.

It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
