Specification of Letters Patent.
Patented Nov. 2, 1909.
To all whom it ymay concern:
Be it known that I, GEORGE S. LEWIS, a. citizen of the United States, residing at Chicopee Falls, in the State of Massachusetts, have invented certain new and useful Improvements in Firearms, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.
This invention has for its object to provide an improved cartridge ejector for breech-loading single shot fire arms, by which the empty cartridge shall be ejected with certainty and quickly when theJ breech is opened.
The invention will be more fully eX- plained hereinafter with reference to the accompanying drawing, in which it is illustrated and in which- Figure l is a view, partly in side elevation and partly in longitudinal section, of so much of a breech-loading rifle as is necessary to enable the application of the invention to be understood. Fig. 2 is a similar view, but showing the breech open. Fig. 3 is a detailed view of the ejector.
The invention is illustrated in the drawing as applied to a single shot breech-loading rifle of ordinary construction comprising a barrel a, a frame or receiver Z), and a stock c, with firing mechanism sufciently indicated by the hammer d and trigger al. These parts, together with the breech block e, pivoted on a screw f, the guard lever g, pivoted on a screw h, and the link z', between the guard lever and the breech block, are constructed and operate as usual in rifles of the character of that shown.
The ejector Za is pivoted as usual upon the screw or pin h on which the guard lever g is pivoted, and is formed at its upper end as at Z to engage the rim of the cartridge as it stands in the chamber of the barrel, the upper portion of the ejector lying in a recess formed therefor in the breech below the cartridge chamber, also as usual. This ejector is also actuated in the usual manner, a shoulder g on the hub of the guard lever g turning the ejector back to withdraw the cartridge when the guard lever is thrown down from the position shown in Fig. l to the position shown in Fig. 2. This operation of the ejector, however, is comparatively slow, being dependent upon the movement of the guard lever by the hand of the user. Such operation of the ejector, therefore, merely withdraws the empty cartridge slowly from the chamber of the barrel, not throwing it backward clear of the receiver or frame of the gun, but leaving it partly engaged in the chamber of the barrel so that the user must complete its removal with the fingers of his disengaged hand. In accordance with the present invention, the ejector is made to snap back with a quick motion so as to withdraw the empty cartridge completely from the chamber of the barrel and throw it backward clear of the frame. To this end the ejector is provided with an enlargement lo', in which is seated a spring- 70 pressed plunger m which has its projecting end beveled olf, with a locking face m on the upper side and a cam face m2 on the lower side. This spring-seated plunger is so placed and arranged as to cooperate with a convenient fixed part of the frame or re` ceiver, such as the pin or screw j above referred t0.
lVhen the breech is closed and the ejector is in its inoperative position, the locking so face m of the plunger bears against the under side of the locking abutment or pin or screw f so as to hold the ejector in its inoperative position. As the guard lever g is thrown down and forward to its extreme position, the shoulder g moves the ejector backward until the edge between the two faces m and m2 of the plunger passes the line oining the centers of the pins or screws f and and the plunger m is then driven forward by the spring m3 on which it is seated, so that the cam face m2 co-acts with the iXed abutment or pin f to throw the ejector quickly backward through the remainder of its travel. The spring m3 being 95 sufliciently stiff, this action of the ejector throws the empty cartridge quickly out of the chamber backward clear of the frame or receiver. The return of the ejector to normal position is effected in a similar manner through the action of the shoulder g2 of the guard lever g, the locking face m of the plunger cooperating with the abutment f to hold the ejector in normal position after it has returned thereto.
I claim as my invention.
l. The combination with a barrel and a frame, of an ejector, means to actuate the ejector by hand and a spring-pressed plunger and abutment carried the one by the ejector and the other by the frame and co acting to effect a quick movement of the 'ejector after it has been moved by hand to Vcooperating with the ejector to move the same, a spring-pressed plunger and abutment, the one being carried by the ejector and the other by the frame and co-acting to effect a quick movement of the ejector after it has been moved by the guard lever to a determined extent. y
3. rlLhe combination With a barrel and a frame of a pivoted ejector, a spring-pressed plunger carried by the ejector and having a cam-face, an abutment With which said plunger co-acts to effect a quick movement of the ejector after it has been moved to a determined extent, and means to effect an initial movement of the ejector.
4. The combination with a barrel and a frame, of a pivoted ejector, a spring-pressed plunger carried by the ejector and having aj cam-face, an abutment With which said plunger c'o-acts to effect a quick movement of the ejector after it has been moved to a determined extent, and a guard lever coperating with the ejector to effect the initial move` ment thereof.-
5. The combination of a barrel, a frame, a pivoted breech-block, a pivoted guard lever connected with the breech block, an ejector pivoted on the same pivot with the guard lever and receiving its initial movement from the guard lever, anda spring pressed plunger carried by the ejector and having a cam-face to coperate With the pivot pin of the breech-block.
