[0001] In hand guns having a revolving cylinder, ammunition of a designated caliber is used,
however, different manufacturers produce sheels of a like caliber but often of different
lengths, having rims in the cap end of the casing of varying diameter. The ejecting
mechanism for removing spent casings and for maintaining the cartridges in the cylinder
in the proper position relative to the firing pin, is usually designed by the manufacturer
for a single gun. The need for a gun that will accommodate all ammunition of the same
caliber is apparent. It is the object of this invention to provide for such a gun.
[0002] The invention provides a positioning and ejecting device for a revolver, having a
cartridge cylinder with a spring loaded longitudinal axle forming an ejector rod which
is movable longitudinally of the clyinder, characterized by an ejector mounted on
one end of said rod, with ejector arms being yieldable and rearwardly and radially
outwardly inclined, the extended ends of each rod having casing engaging means to
maintain a cartridge casing in firing position in said cylinder and for ejecting said
casing upon longitudinal movement of said rod.
[0003] The ejecting device for revolvers having the usual cylinder includes a movable axle
longitudinally mounted in the longitudinal axis of the cylinder, said axle having
rearwardly and outwardly inclined casing contacting arms, formed of a light spring
material, and the extended ends of which are shaped to permit a casing rim to bear
against and raise the arm. When loading from the front, and using a front loader as
described in U. S. Patent 4,318,239, as the rim of the casing passes the end of the
ejector, the ejector will drop back into casing holding position, engaging the rim
of the casing. When loading from the rear of the gun, the rim of the casing will be
engaged by the end of the ejector and held in firing position. In either instance,
when the casings are spent or it is desired to unload the gun, the ejector may be
actuated in the usual manner and the casings discharged from the cylinder. A ratchet
plate is detachably mounted on the end of the axle, and provides means for revolving
the cylinder in the gun in the usual manner.
[0004] In the drawings:
Figure 1 is a side elevational view of a gun.
Figure 2 is an enlarged end view of the cylinder, with the ratchet plate partially
broken away.
Figure 3 is a cross-sectional view taking on the line 3-3 of Figure 2, showing a cartridge
in dotted lines in the middle of a cylinder bore.
[0005] In the drawings, the numeral 1 designates a gun frame in which a cylinder 2 is mounted
on a crane 3 to be swung outwardly for loading and unloading, in the usual manner.
An ejector rod 4 extends through the longitudinal axis of the cylinder 2, and extends
along the bottom of barrel 5, also in the usual manner, and is spring loaded to maintain
the rod normally in retracted position, also customary for revolvers of all makes,
and has one end reduced and externally threaded, as at 6. An ejector 7 is mounted
on the reduced end portion, having a port 9 in one end to receive said reduced portion,
and seats against a shoulder 8 with the threaded area 6 of the rod 4 extending through
said port 9. Extending rearwardly and inclined outwardly are the ejector arms 10-10,
formed of spring material and each being trans- versly concave at the extended ends
and having a notch 11 formed in the extended end and having the area beneath the notch
11 tapered upwardly and outwardly as 12.
[0006] Mounted on the end of the threaded portion 6 of the rod 4 is the ratchet plate stem
14, which is internally threaded as 15 and a ratchet plate 13 is fixedly mounted on
the other end, and adapted to be engaged by the revolving mechanism of the gun (not
shown) in the usual manner.
[0007] When the plate 13 is mounted on the rod 4, there will remain a space between the
plate and the extended ends of the ejector arms 10, 10 so that the rim of a casing
being loaded from the front is inserted into a bore of the cylinder and will bear
against the extended end of the ejector arm as the rim bears against the tapered end
12 of the ejector arm 10, the arm 10 yields upwardly and inwardly and the rim moves
past the end of said arm and permits the end of the arm 10 to drop back into its original
position so that the notch 11 will engage the rim of the casing holding the casing
in position for firing. When loading from the rear, the arm 10 will yield inwardly
and upwardly to permit the casing to enter the cylinder bore until notch 11 engages
the casing rim and the end of the arm extends into the casing groove. All casings
have the peripheral groove 16. The distance of travel of the ejector arms 10 as a
casing is inserted in a cylinder bore, will permit the engagement of any casing of
the designated caliber, so that either rim or rimless cartridges may be loaded in
the cylinder, the ejector arm holding each cartridge in the desired position with
relation to the firing pin of the gun, regardless of the length of the casing or the
projectile.

with a spring loaded longitudinal axle forming an ejector rod (4) which is movable
longitudinally of the cylinder, characterized by an ejector (7) mounted on one end
of said rod (4) with ejector arms (10) being yieldable and rearwardly and radially
outwardly inclined, the extended ends of each rod (10) having casing engaging means
(11, 12) to maintain a cartridge casing in firing position in said cylinder (2) and
for ejecting said casing upon longitudinal movement of said rod (4).
2. The device of claim 1, characterized in that a ratchet plate (13, 14) is mounted
on the rearwardly extended end (6) of said rod (4) and spaced from said ejector arms
(10).
