MECHANISM FOR BREECH-LOADING SMALL-ARMS.

SPECIFICATION forming part of Letters Patent No. 443,635, dated December 30, 1890.

' Application filed March 22,1890. Serial No. 344,940. (No model.)

To all whom it may concern:

Be it known that I, THOMAS SOUTH GATE, a citizen of England, residing at 6 Burton Orescent, London, England, have invented new 5 and useful Improvements in Ejector Mechanism for Breech-Loading Small-Arms, of which the following is a specification.

My invention relates to certain improve ments in the ejector mechanism for single and double barreled breech-loading small-arms.

My improved ejector mechanism consists of an ejector-tumbler acting upon the ex tractor, and of an ejector-spring in the fore end, a projection on the firing-tumbler having a bent out in it, and a sliding bar having a spring to act upon it in a manner to be described. This sliding bar forms the means of communication between the firing and ejecting tumblers. The object of the spring is to obviate the necessity of moving the sliding bar by the fall of the firing-tumbler, which is objectionable, because such moving of the sliding rod by the fall of the firing-tumbler lessens the blow given by the said tumblers 2 5 to the striker. I cause the spring to hold the bar always as far forward as the ejector-tunibier will allow, and therefore out of the way of the projection on the firing-tumbler at the moment of firing. The sliding bar may be modified in form to suit different types of actions, but its function is always the samenamely, to act as a means of communication between the firing and ejecting tumblers. The ejector-tumbler is of the following form: reaching upward and acting upon the extractor is a long arm, which is circular at the front, and thiscircular front is cut away at a sharp angle toward the axis of the tumbler. Reaching downward is a short arm which is cam. The sliding rod is held against this circular back of the short arm of the ejectortumbler by the spring which I cause to act upon the sliding rod. The free end of the ejector-spring bears on the circular front of the ejector-tumbler, except at the moment of ejection, when the spring takes onto the flat part, giving the said ejector-tun1bler a sudden jerk round. "With my improved ejector made circular on the back so as to form a' mechanism no sear or sear-spring is required, neither is an injector-cam required, as the ejector-tumbler fulfills the ofiice of the ordinary extractor-cam in addition to acting as an ejector-tumbler when the gun has been fired.

My invention will be understood by refer- 5 once to the accompanying drawings.

Figures I and II show my invention as applied to side-lock guns, and Figs. III and IV show the application of my invention to the Anson-Deeley type of gun.

In Fig. I the gun is shown as having been fired and in Fig. II as having been opened after firing, and the various parts of the mechanism are shown separately under Fig. I.

The sliding bar (6 is pressed forward by the spring g and held against the ejector-tumbler c. The spring g takes its abutment against the nut 71, through which the bar is free to move longitudinally with also a slight amount of freedom in a vertical direction.

On the firing-tumbler is a projection I), having a bent b cut-in it. The bar a extends from this projection b tothe ejector-tumbler c. It will be seen that the bar a, being held forward by the spring g, is never moved by the fall of the firing-tumbler.

On opening the gun after firing the following operations ensue: As the barrels are turned downward the bar a will be jammed between the short arm of the ej ector-tumbler c and the So projection 12 on the firing-tumbler, and therefore as the firing-tumbler is being cooked the bar a will be carried slightly upward, and thus prevented from sliding into the bent b in the projection l) on the firing tumbler. Therefore the bar a is held forward by the projection 1) during the whole time of opening the gun. The bar a, being thus held forward, will cause the ejector-tumbler o to turn on its axis, and as a first result the extractor f will be pushed backward. While this movement is taking place the rotation of the ejectortumbler c on its axis causes the end of the spring cl to slide along the circular part of the ejector-tumbler toward the fiat part. 5 WVhen the spring d reaches the flat part of the ejector-tumbler c, it causes the said tumbler to be jerked round, giving the extractor the required sudden impulse needed for ejection of the cartridge-case. These movements are so timed that the act of ejection takes place when the chamber of the barrel has risen clear of the standing-breech. Should the gun be opened with the firing-tumbler at full-cock, the bar a will be pushed back into the bent b in the projection b, and as a result the ejector-tumbler will be turned far enough on its axis to press back the extractor to the unloading position, but not far enough to bring the spring d to act on the fiat part of the ejector-tumblerc. Therefore no ejection of the cartridge will take place.

Figs. III and IV show my improved ejector 1 mechanism as applied .to the Anson-Deeley type of action. Fig. III shows the gun closed and fired, and Fig. 1V shows the gun as opened after firing. The parts of the mechanism are also shown separately.

'Similar parts in Figs. III and IV bear the same letters of reference as in Figs. I and II.

It will be observed that the projection 12, with thebent b on the firing-tumbler, the ejector-tumbler c, and the ej ector-sprin g d, are similar to those already described; but the bar a is modified in form, as is also the spring foractuating the same. The sliding bar a, as before, reaches from the projection Z) on the firing-tumbler to the ejecting-tumbler 0. At-

tached to the bar ais a spring g, of the form shown, bearing against the stud h. This spring holds the bar a downward and also presses it forward against the ejecting-tumbler c. The gun having been fired and the mechanism being in the position shown in Fig. III, on opening the'gun ejection will ensue by a series of movements exactly analogous to those described in relation to Figs. I and II-that is to say, the resistance of the bar a abutting against the projection b will turn the ejectortumbler first to the unloading posit-ion of the extractor, and then bringing the ejector-spring onto the flat part of the ejector-tumbler will cause the extractor to receive the sudden impulsewhich causes ejection of the cartridgecase, and the parts will then be in the position shown in Fig. IV. Should the gun be opened with the firing-tumblerat full-cock, no ejectin g action will ensue, as previously described. On closing the gun the parts will assume the position shown in Fig. III, except that the firing-tumbler will be at full-cock and the rear end of the bar a will be opposite the bent b'.

The spring g may be omitted without affecting the action of the mechanism for extraction and ejection, but the fall of the firingtumbler would be slightly impeded by the bar a.

Having thus described the nature of this invention and the best means I know for carrying the same into practical effect, I claim- The combination, with the fore-end and barrel of a breech-loading fire-arm, of a: sliding extractor f on the barrel, the ejector-tumbler c, pivoted on the fore-end'and having a long arm above its pivot acting on the extractor,

and provided with a convex front which is cut away at a sharp angle toward the pivot to form a flattened face, said tumbler also having a short arm below its pivot provided with a cam-back, a spring d at the fore-end adapted to bear against the flattened face of the tumbler for imparting the ejecting impulse to the extractor, the sliding bar at, having its forward end bearing against the cam back of the tumbler, and the firing-tumbler having a projection I), provided with a bent I), to act on the rear end of the sliding bar, substantially as described. 1

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 7th-day of.

March, A. D. 1890.
