ABSTRACT:
BACKGROUND OF THE INVENTION
I. Field of the Invention
This invention relates to improvements in cartridge holders and is particularly directed to cartridge holders adapted to releasably secure a round of cartridges for fast and simultaneously loading of the round into the chambers and the cylinders of revolvers.
II. Description of the Related Art
It is well known in the art to utilize a cartridge loader in loading cartridges into a revolver or other weapon. U.S. Pat. No. 3,722,125 to Switzer discloses a holder that releasably secures a round of cartridges within cartridge bores in a cylindrical housing. A manually rotated member selectively secures or releases the cartridges into the cylinder of the revolver. A positioning mechanism is provided to maintain the holder in either a release position or an engaged position. This locking mechanism is formed of several members and extends externally of the housing.
An improved cartridge loader by the same inventor is disclosed in U.S. Pat. No. 4,202,124. The cartridge loader has a star-shaped latch that selectively engages/releases the cartridges. A semi-automatic rotation device may be utilized to rotate the latch. The rotation device is also manually operable to set the latch from the releasing position to the capturing position by rotating a knob. Again, the mechanism that locks the loader into either a engaging position or a releasing position includes many members and extends outwardly from the loader body.
Another known type of cartridge loader is disclosed in U.S. Pat. No. 5,842,299 to Switzer et al. This patent is primarily directed at providing a cartridge loader for more than the standard five- or six-chambered revolver. However, a portion of the locking system for selectively positioning the holder into engaging or releasing positions is still located externally from the holder's casing.
Each of the aforementioned prior art cartridge loaders have externally extending members that reduce the efficiency of cylinder loading by creating a gap between the cartridge holder and the revolver's cylinders. One problem addressed by the present invention is that the cartridges may fall sideways instead of within the appointed cylinder due to the gap. Another problem addressed in the present invention is that damage or breakage could occur to exposed parts if the loader is dropped or otherwise subjected to force.
The present invention has no external parts to be broken off, and also efficiently loads the cartridges into the revolver.
The present invention contemplates a new and improved loader for a revolver, which is simple in design, effective in use, and overcomes the foregoing difficulties and others while providing better and more advantageous overall results.
SUMMARY OF THE INVENTION
In accordance with the present invention, a new and improved cartridge loader for a revolver is provided. The cartridge loader includes a cylindrical loader body having spaced first and second surfaces, a cylindrical central cavity extending from the first surface into the loader body and a plurality of circumferentially located cartridge bores extending from the second surface into the loader body. A selectively rotatable pintle is received within the central cavity and operates between a closed position, at which cartridges may be temporarily stored, and an open position at which the cartridges may be released. Latching means are carried on the pintle and operable therewith. The latching means include a plurality of cartridge-engaging protrusions, each of which intersect a different one of the cartridge bores when the pintle is in the closed position and do not intersect the cartridge bores when the pintle is in the open position. The cartridge loader includes détente means positioned between the spaced surfaces of the loader body which selectively locate the pintle at the closed or open positions.
In accordance with another aspect of the invention, the détente means comprises a pin assembly including a lock pin and a spring wherein the lock pin is adapted for reciprocal movement in a plane generally perpendicular to the axis of rotation of the pintle; a pin-engaging surface including a first pin groove and a second pin groove wherein the lock pin is resiliently engaged in the first pin groove to locate the closed position of the pintle and resiliently engaged in the second pin groove to locate the open position of the pintle; and, reciprocating means for reciprocating the lock pin, the reciprocal means being positioned intermediate said first and second pin grooves.
In accordance with another aspect of the invention, the pin-engaging surface is formed in the pintle and the reciprocating means is a ball bearing held in a bearing groove formed in the pintle.
In accordance with another aspect of the invention, the pin-engaging surface is formed in the pintle and the reciprocating means is a rise formed in the pintle.
In accordance with another aspect of the invention, the central cavity extends a length less than a distance between the first and second surfaces of the loader body.
In accordance with another aspect of the invention, each of the cartridge bores extends a length less than a distance between the first and second surfaces of the loader body.
One advantage of the present invention is that the revolver can be quickly loaded.
Another advantage of the present invention is the simplicity of design as compared to other prior art loaders.
Another advantage of the present invention is that the détente means is contained within the loader body and is protected from contaminants and debris.
Another advantage of the present invention is the permanent assembly of the associated parts.
Still another advantage of the present invention is that the locking mechanism is internally located to prevent damage to exposed parts.
Yet another advantage of the present invention is that the absence of external projections on the side placed next to the revolver chamber permits more efficient loading of the cartridges.
Still other benefits and advantages of the invention will become apparent to those skilled in the art upon a reading and understanding of the following detailed specification.
