However, my imsists in the combination, with a breech-cloprovement is applicable to guns having sure, of an extractor movable independently breech-blocks or breech-bolts or other kinthereof and a spring-actuated extractor-dedred forms of breech-closures.

5 tent arranged to engage with the extractor Inasmuch as the operation of the breechand hold the same in its extreme retracted block and extractor are substantially the position, with its forward end extending besame as the operation of the corresponding yond the forward end of the breech-closure, parts in the gun of the Lee patent before reuntil the same has in its forward movement ferred to, it seems unnecessary to further 50 come up with the forward end of the extracdescribe the detailed construction and opcr- I00 ation of these parts or to do more than specify the operation of the spring-actuated extractor-detent, which constitutes the gist of my present invention. In the description of the operation of the said detent I may say that when the extractor D reaches the limit of its rearward movement, as shown in Fig. 1, the spring-actuated plunger A snaps into its notch d, as shown by broken lines in Fig. 1. After this the breech-block moves slightly rearward and then reaches the limit of its open position, as also shown in Fig. 1. Now when the breech-block begins its forward movement it does not, notwithstanding the friction between it and the extractor, start the same forward (except to engage the rear wall of its notch d with the plunger) until its forward end has come up with the forward end of the extractor, as shown in Fig. 2, at which time the block is positively engaged with the extractor. The forward push on the block then overcomes the spring of the plunger which retires to permit the block and extractor to move forward together in the positions in which they are shown in Fig. 2.

In the Lee patent referred to the extractorspring D is employed to act as an extractordetent, but under some disadvantages, which are entirely overcome by the employment of an independent spring-actuated detent, as herein shown and described.

It is apparent that in carrying out my invention some modifications in the extractordetent may be resorted to. Thus I may find it convenient to employ an extractor-detent consisting of a flat spring H, adapted to be located in the path of the extractor and provided with a small projection II to enter a notch in the extractor. Such a modified detent is shown in Figs. 7 and 8. I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes in the construction as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a firearm, the combination with a breech-closure, of an extractor movable independently thereof, and a spring-actuated extractor-detent organized independently of the extractor and arranged to engage with the same and temporarily hold it in its retracted position.

2. In a firearm, the combination with the breech-closure thereof, of an extractor movable independently thereof, and a springactuated extractor detent consisting of a plunger arranged to engage with the extractor when the same is in its retracted position and detain the same and hold it against forward movement while the breech-closure is moving from its open position and coming up with the forward end of the extractor, which it then picks up and carries forward.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
