EJECTOR FOR RIFLES.

Specification of Letters Patent. P te ted Mar. 30, 19,20.

Application filed'August 6, 1919. Serial No. 315,615.

To all whom it may concern Be it known that 1,,HARRY A. Lnwis, a

citizen of the United States of America, and

resident of the city of Boston, countyv of Suffolk, and State of li lassachusetts, have invented certain new and useful Improvements in Ejectors for Rifles, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.;

'My invention relates to the construction of rifles, particularly to ejector mechanism, and has, for its object to provide a simple, durable and inexpensive ejector mechanism, and particularly to provide an ejector actuating spring which'will not be liable to breakage.

My invention has been particularly ,dc-

vised for use in connection with rifles of the type known as the British Enfield or the American modified Springfield, and it is illustrated in the drawings forming a part of this specification in this connection with the coacting parts of the breech mechanism of such a rifle.

The nature of my improvements will be best understood as explained in connection with the drawings in which Figure l is a horizontal section taken as on the line ll of Fig. 2 and showing the bolt stop and ejector mechanism.

Fig. 2 is a side elevation of the portion of the breech embodying the mechanism shown in Fig. 1.

Fig. 3 is a view generally similar to Fig. 1, but showing the bolt stop unsectioned.

Fig. fl: is a view generally similar to Fig. 1 showing the bolt in retracted position, and one of the lugs D to be hereafter described, in section.

Fig. 5 is a cross sectional view taken as on the line 55 of Fig. 4.

Fig. 6 is a perspective view of the bolt stop.

Fig. ejector.

Fig. 8 is a similar perspective view of the ejector and actuating spring as heretoiore used in rifles of the kind referred to.

A indicates the solid material of the rifle breech having formed in it an opening as in dicated at A through which extends the bolt stop and the active end of the ejector. At the rear end of this opening are formed the lugs A A and still farther in the rear, as shown, is a circular opening indicated at A.

7 is a perspective view of the On the opposite side of the. breech. formed the opening indicated at A through which the magazine communicates with the breech. B; is the bolt, '13.. being the end against, which the, cartridge abuts, 13 a projecting lip which contacts with one portion of the cartridge rim. The upper part of the stop lug on the bolt on which the lip B is formed, is grooved as indicated at l for thepassage of the active end of the ejector. ,liv .is a groove formed in the body of the bolt for the reception of a ring to. be described. G is a block havin formed on it the finger C, .which engages t he rim oi the cartridge, and l'earwardly of said linger another finger C which projects into a groove B? formed in thebolt B. The block C issecured to. a bolt C which.moves in a slot formed in the breech frame, and, as shown, has secured .toit an inwardly pro jecting shoulder C to which is secured a ring C secured in turn in the groove B oi the bolt. D is the bolt stop formed with an inwardly extending stop finger D and with pivot perforations, as indicated at D at its rear end. This bolt stop, which is best shown in Fig. 6, is formed with lugs as indicated at D D the slot D separating such lugs, and it is also formed with a projecting ledge D to aflord a grip for raising it. E is the pivot on which the bolt stop is secured, which extends through the perforations in the lugs A F is the ejector which, as shown, is also pivoted on the pivot pin E, which passes through a perforation F in its rear end. F 2 is a projecting lug or camlike shoulder formed on the ejector near its pivoted end for purposes to be hereafter explained. G is a spring rest having a projecting pin G which extends into the perforation A, and formed, as shown, with transverse slots G and G in its head. As shown in the drawings this device .6 serves not only as a spring rest but also has attached to it a sight rod H, carrying a sight H at its end, and which can be folded down, as shown in Fig. 2, and thrown up into active position by turning the rest Gr through an angle of 90. I is a plate spring having downwardly projecting lugs I, I, which engage on the lugs D of the bolt stop, as indicated in the drawings, the rear end of the spring resting in a groove of the spring rest G, and pressing against.

such spring rest acting to keep the bolt stop in the position shown in the drawings.

' great many break in use.

In all particulars shown the drawing,

with the exception of the formation of the 'ejectors constructed as shown inFig. 8 of the drawing, and in which a spring tongue F is sawed out of the material of the ejector and in assembled relation presses against the spring I with the result of pushing the active end of the ejector downward. This construction has proved defective for the reason that a great many of the ejector springs are broken in manufacture and a In my construction in place of using a spring such as F 3 I form the camlike shoulder F on the ejector bar of such shape and dimensions that it will press against the spring I, which springis' thereby given the double function of holding down the bolt stop and of exerting the necessary downward pressure upon the active end of the ejector It will be understood that when thebolt is in advanced position, as shown in Figs. 1, 2 and 3, the ejector is pressed upward and held in the position indicated in Figs. 1 and 3. When the bolt is retracted the active end of the ejector passes down through the slot B and striking the rimof the cartridge throws it out of the opening formed in the breech for that purpose, the final position of the ejector in the rearward movement of the bolt being shown in Fig, 4.

Having now described my invention, what I claim asnew and desire to secure by Letters Patent, is:

1. In a rifle, the combination of a pivoted retractable bolt stop and a spring holding the stop in active position, with an ejector pivotally supported at its non-active end and formed with an unyielding shoulder bearing against and acted upon by the bolt stop spring. I l

2. In a rifle, the combination of a pivoted retactable bolt stop and a spring holding the stop in active position with an ejector pivotally supported on the bolt stop pivot at its non-active end and formed with an unyielding shoulder bearing against and acted upon by the bolt stop spring.

3. In a rifle, a bolt stop pivotallysupported on the. rifle breech, in combination with a plate spring secured-to the bolt stop, a support for the free end of the spring at the rear of the pivotal support and an ejector also pivotally supported on the breech and formed with an unyielding shoulder bearing against the plate spring.

I. In a rifle, a bolt stop pivotally supported on the rifle breechin combination with a plate spring secured to the bolt stop, a support for the free end of the spring at the rear of the pivotal support and an ejector also pivotally supported on the breech on the bolt stop pivot and formed with an unyielding shoulder bearing against the late s rin p HARRY A.
