SHELL EXTYRACTOR AND EJECTOR FOR BREAKDOWN GUNS.

SPECIFICATION forming part 0f Letters Patent N O. 660,227, dated October 23, 1900. Application filed Apiil 6,1900. Serial No. 11,820. (No model.)

To LZ whom it may concern/.-

Beit known that I, PHILIP W. SOUTHGATE, a citizen of the United States, residing at Vorcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful Shell Extractor and Ejector for Breakdown Guns, of which the following is a specification.

This invention relates to a combined eX- tractor and ejector for breakdown guns, which is designed to first impart a positive starting motion to the shell and which will permit the ejector-spring to throw the shell completely out of the gun when the gun is wide open.

The especial objects of this invention are to simplify the connections for moving and controlling the ejector-bolt and to provide a simple,ldurable, and inexpensive form of construction which may be secured in place with comparatively little machine-workand without the cutting away of enough metal to materially weaken the barrel-lug.

To these ends this invention consists of the combined extractor and ejector and of the combinations of parts therein, as hereinafter described, and more particularly pointed out in the claims at the end of this specification.V

In the accompanying drawings, Figure 1 is a sectional View of sufficient portions of a gun to show the application of my invention thereto and illustrate the parts in their normal or` closed position. Fig. 2 is a similar viewshow ing the gun partially opened and illustrating' the position of the parts when there is no shell in the gun or when the shell does not stick, so as to require a positive motion to be imparted thereto. Fig. 3 is a similar .view

showing the position of the parts when thel gun is fully opened, and Fig. 4 is a sectional view taken on the line 4 4 of Fig. 1.

To secure a satisfactory ejector action for.

breakdown guns,it is desirable to rstiinpart a short positive motion to the ejector-bolt to start the shell back out of its chamber and to provide a detent mechanism which will not release the ejector-spring until the gun is fully opened, so that the shell may be thrown completely out of place by the spring action of the ejector-bolt.

The connections which have heretofore been rel, having a barrel-lug 12.

employed for imparting an initial or positive motion to the ejector-bolt have been so complicated as to require considerable machinework forlsecuring them in place and in some Vinstances. have required the cutting or milling out of the barrel-lug to such an extentas to weaken the same to an undesirable degree. On this account many gun-.manufacturers have preferred to rely entirely upon the action of the ejector-spring rather than to attempt to impartapositiveinitial motion to the ejector-bolt to secure an extractor action therefrom. The especial object of my present invention is therefore to provide a construction for imparting a positive or initial motion to the ejector-bolt which is so simple and eflicient that it may be applied to a gun without additional cost and which may be secured in place without weakening or cutting out the barrel-lug to an undesirable extent. To accomplish this object, I propose to effect the entire operation and control of the ejector-bolt by means of a single piece or detent-thatisto say, a combined extractor and ejector constructed according to my present invention consists of a spring-pressed Iejector-bolt and a detent therefor', said parts having engaging cam-faces for imparting a positive motion to the ejector-bolt as the gun is opened.

Afurther object of my present invention is to arrange the parts so that the detent will not only serve to impart a positive motion to the ejector-bolt and to control the release of the ejector-spring, but in addition to this the detent will also act as a key for prevent-ing the turning or removal of the ejector-bolt when the gun is taken apart.

Referring to the accompanying drawings,

lwhich illustrate a combined extractor and uejector constructed according to my invention, 10 designates the frame, and 11 the bar- Mounted in a hole bored longitudinally in the barrel-lug 12 is an ejector-bolt 14, having a spring 15, normally tending to move the same back. The 'ejector-bolt 14 is transversely slotted, so as to be provided with a recess preferably having sections of different depths, one section 16 of the recess being deeper than a shallower section 17. At the end of the recess in the ejector-bolt 14 is an incline or cam face 18. Cooperating with the ejector-bolt and mounted on the hinge-pin 13 or otherwise pivotally supported substantially in the line of motion of the ejector-bolt l4 is a detent-lever 19. The detent-lever 19 is mounted in a longitudinal recess or slot in the barrel-lug 12 and may be secured in place, so as not to fall out' when the gun is taken apart, by means of a pin or wire 2O engaging a notch therein, as shown most clearly in Fig. 4. The front end of the detent-lever 19 extends forward in front of the hinge-pin 13 in position to engage the front of the frame when the gun is opened, and at its rear end the detent-lever 19 is provided with a detent-head 21 for engaging the transverse notch or recess in the ejectorbolt 14. The detent-head 21 is provided with a rear incline or cam face, which normally rests upon and engages the cam-face of the ejector-bolt 14 when the gun is closed, as illustrated in Fig. 1. A spring 22 normally holds the detent-lever in engagement with the ejector-bolt.

In the operation of a combined extractor' and ejector as thus constructed as the gun is opened the ej ector-bolt will first be allowed to move back a short distance, as illustrated in Fig. 2, and when the gun is fully opened, as illustrated in Fig. 3, the detent will be withdrawn sufficiently to permit the ejectorbolt to fly back, as illustrated in Fig. 3. When the gun is empty or when the shell therein does not stick, the action of the spring of the ejector-bolt will be sufficient to throw the shell out of the gun. Whenever a shell sticks or becomes wedged in the gun so tightly that the ejector-spring is not strong enough to displace it, the incline or cam face of the ejector-bolt and the corresponding incline or cam face of the detent will first serve to impart a positive rearward motion to the ejectorbolt before the ejector-bolt spring is released.

In the construction herein illustrated the detent is never completely withdrawn from the recess in the ejector-bolt, so that, as illustrated in Fig. 3, the detent itself may serve as a stop for the rearward motion of the ejector-bolt, and will act as a key for preventing the removal or rotation of the ejector-bolt.

I am aware that changes may be made in applying my combined extractor and ejector to breakdown guns. For example, an ordinary stop-screw maybe employed for holding the ejector-bolt in place and for preventing its removal in the ordinary manner, if it is not desired to have the detent itself act as a key for holding the ejector-bolt in place. I do not wish, therefore, to be limited to the construction herein shown; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

1. In a breakdown gun, the combination of a spring-pressed ejector-bolt, and a detent for preventing the ejector-bolt from 'liying back until the gun is substantially wide open, said parts having engaging cam-faces for imparting a positive motion to the ejector-bolt as the detent is withdrawn, substantially as described.

2. In a breakdown gun, the combination of a spring-pressed ejector-bolt having a recess with an incline or cam face at the end thereof, and a detent fitting into said recess so as to prevent the ejector-bolt from flying back until t-he gun is substantially wide open, and having a cam-face for imparting` a positive motion to the ejector-bolt when the detent is withdrawn, substantially as described.

3. In a breakdown gun, the combination of a spring-pressed ejector-bolt having a recess with an incline or cam face, and a springpressed detent-lever pivoted substantially in the line of motion of the ejector-bolt, and having an integral detent-head fitting into the recess in the ejector-bolt and having an incline or cam face engaging the inclined face of the ejector-bolt to impart a positive motion to the ejector-bolt when the detent-lever is turned, substantially as described.

4. In a breakdown gun, the combination of the frame, a barrel having a lug fitting therein,a hinge-pin pivolfallyconnecting said parts, an ejector-bolt fitting into a hole bored longitudinally in the barrel-lug, said ejector-bolt having a recess with an incline or cam face at the end thereof, a spring normally tending to move back the ejector-bolt, a detent-lever mounted in alongitudinal slot in the barrellug and pivoted on thehinge-pin substantially in the line of mot-ion of the ejector-bolt, the front end of said detent-lever extending forward in front of the hinge-pin, and the rear end of said detent-lever having an integral detent-head with an incline or cam face corresponding with t-he incline or cam face of the ejector-bolt, and a spring normally holding the parts in engagement so that when the gun is opened a positive motion will be imparted to the ejector-bolt as the detent-head is withdrawn from the recess in said ejectorbolt, substantially as described.

5. In a breakdown gun, the combination with an ejector-bolt which is transversely notched to form a recess having parts of different dept-hs, one side of said recess being formed by an incline or cam face, and a detent engaging said recess and having a corresponding incline or cam face for imparting a positive motion to the ejector-bolt when withdrawn from the deeper part of said recess and acting as a stop or key for limiting the motion and preventing the withdrawal of the ejector-bolt while in engagement with the shallower part of said recess, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
