"FIREARLVL Application led July 18, 1923, Serial No. 652,386. Renewed November 17, 1925.

To all whom -i may concern:

Be it known that I, CARL GUs'rAr SwimmrUs, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Firearms, of which the following is a specification.

l1`his invention relates to firearms and has for its object to render easy the cleaning of a firearm.

In certain types of firearms, the ejector is pivoted in a slot in one wall of the receiver and a spring is provided to project one end of the ejector away from the wall to bring it into position to engage a shell to be ejected. When such a gun is being cleaned the ejector often catches on the cleaning tool rendering difficult the cleaning of the gun and sometimes resulting in the breakage of the ejector parts.

The object of this invention is attained by providing means whereby the ejector may be retained substantially within its slot, thereby rendering possible comparatively free passage of a cleaning tool. Furthermore, this arrangement obviates the possibility of the ejector being caught by the cleaning tool and broken oif during cleaning of the gun.

Referring now to the drawings, Fig. 1 is a plan view partially broken away of the receiver of a gun embodying the invention; Fig. 2 is a similar view with the ejector held back; Fig. 3 is a vertical section through the receiver; and Fig. 4 is an enlarged detail view of the retaining means.

In one wall of the receiver 10 is a groove within which is received a plate 11 having an aperture 12. An ejector' 13 has one end pivotally attached to the plate 11 and is adapted to lie within the aperture 12. A spring 1-1, attached to the wall of the re.- ceiver and lying in the groove therein, is Vadapted to project the free pointed end 1a of the ejector' 1S into the receiver in position\ to engage a shell to be ejected. As shown in Fig. 1, the ejector assumes the above described position when the gun is taken down or made ready for cleaning. The ejector is thus in the path of cleaning tool and the cleaning of the gun is rendered difticult.

To overcome this diiiieulty, a rotatable member 16 is provided at the forward end of the plate 11. This member, while rotatable,

,parent from Figs. 1 and 3.

is set sufficiently tight in the plate that it will not rotate from any vibration or friction of the working parts of the gun. The head 17 of the member 1G is of larger diameter than the portion in the plate so that it projects into the aperture 12. A portion of the head, however, is cut away so that, in one position thereof, it does not project into the groove. The shape of the head is ap- The head is provided with a slot 18 to receive a screw driver or the like whereby it may be rotated.

IVhen the gun is ready for firing, the head is in the position shown in Fig. 1 with no portion projecting into the aperture 12. TWhen it is desired to clean the gun, the ejector 13 is forced into the aperture 12 by a rod, or the like, inserted through the ejection opening and the head 17 rotated to bring a portion thereof over the end 15 of the ejector as shown in Figs. 2, 3 and 4. The ejector is thus retained substantially within the aperture 12 and does not interfere with the ready use of cleaning` tools. The barrel may thus be readily cleaned from either end.

IVhat is claimed is:

1. In a fire-arm, a pivoted ejector, resilient means for projecting one end of said ejector into position to engage a cartridge, and a member adapted to maintain the cartridge engaging end of said ejector in inoperative position.

2. In a fire-arm, a. pivoted ejector, resilient means for projecting one end of said ejector into posit-ion to engage a` cartridge, and a rotatable member having a portion adapted to engage the cartridge engaging end of said ejector to maintain it in inoperative position.

3. In a firearm, a receiver having a groove in one wall, a spring` pressed pivoted ejector in said groove, and means to maintain said ejector within said groove, said means having no portion projecting beyond the surface of said wall.

if. In a firearm, a receiver having a groove in one wall, a spring pressed pivoted ejector in said groove, and a rotatable member having a portion adapted to engage thev cartridge engaging end of said ejector to maintain it within said groove.

5. In a firearm, a receiver having a groove in one wall, an apertured plate in saiol tlf) plate and adapted to be received in said 10 aperture, a spring adapted to project one end of said ejector into said receiver, and a rotatable member having a portion adapted to enga-ge said ejector to maintain it Within said aperture. l In Witness whereof, I hereunto aiiix my signature this 22d dav of May, 1923.
