Description
Filed Oct. 5, 1938 Inventor Attorneys Patented Apr. 2, 1940 UNl'iED STATES was FFECE Ralph Wood,
Application October 5,
2 Claims.
This invention relates to a supplemental rifle chamber and has for its primary object, the provision of a device of this character which will permit low power cartridges to be used successfully in a rifle designed for a high power cartridge, both ammunitions having the same size bullets, and which provides for economy in target shooting and the shooting of small game, allowing the person to have all of the advantages provided by a rifle designed for large caliber ammunition, without the expense attached to such ammunition.
Another object of this invention is the provision of a device of this character which may be safely used, and which will withdraw a shell or cartridge after being fired and which will operate in a rifle oi the magazine type.
With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and the accompanying drawing, in which:
Figure l is a vertical sectional view illustrating a supplemental rifle chamber having therein a cartridge of a small caliber.
Figure 2 is a side elevation illustrating one of no the members of the supplemental rifle chamber.
Figure 3 is a vertical sectional view illustrating another member of the supplemental rifle chamber.
Figure 4 is a transverse sectional view taken on 35 the line 3-4 of Figure 1.
Referring in detail to the drawing, the device is indicated in its entirety by the character 5 and consists of telescopic members ii and l which when assembled have an exterior shape of a shell of a high powered cartridge so as to fit a rifle of this type and its purpose is to support in the rifle a low powered cartridge 8 with the bullet 9 thereof protruding a proper distance therefrom to enter the rifle barrel as would the bullet of the cartridge of the shell designed for the rifle of that particular caliber.
The member 6 is in the form of a sleeve having an internal shoulder iii and a reduced bore ii to receive the cartridge 3 with the rim 52 thereof engaging the seat Ill. The remaining portion of the bore of the sleeve is of a size to slidably receive a reduced portion 23 of the member l with a frictional grip capable of preventing the members 6 and T from being separated. The reduced portion of the member 1 provides in the ill Lawton, Okla.
1938, Serial No. 233,488
latter an external shoulder id to be abutted by the end of the member 6 when the members 6 and l are assembled together as shown in Figure 1. The members 6 and i have grooves IE to aline when the members 6 and l are assembled together and receive therein a spring split-type ring it, the purpose of which is to secure the members 5 and l assembled together against accidental separation, but which will permit the member I to be withdrawn from the member 6 whenever desirable to place in the member 6 or remove therefrom the small caliber cartridge 8.
The member I besides having the reduced portion 13 to form the shoulder M is also provided with a reduced portion IT forming a shoulder IS. A sleeve 59 is mounted on the reduced portion I! and is secured thereto by a pin 28 fitting in openings provided in the reduced portion ll of the member 1 and the sleeve is. The sleeve l9 extends a limited distance beyond the end of the portion I I and is provided with an inwardly tapered flange 2| to engage under the rim of the cartridge 8. The other end of the sleeve l9 abuts the shoulder l8.
The member i has extending endwise thereof a bore 22 to slidably receive an auxiliary firing pin 23. A portion of the bore 22 is slightly enlarged and one end of the firing pin 23 is enlarged to match the enlarged portion of the bore and said end is exposed through the flanged end of the member I and recessed to be engaged by the firing pin of the rifle. The other end of the firing pin 23 engages with the cartridge 8 and as shown in Figure 1 the bore is disposed at an angle to the longitudinal axis of the member i so that the firing pin 23 will contact the edge of the rim E2 of the cartridge 8. In this instance, the cartridge being of the rim fire type. However, should the cartridge be of the central cap type the bore 22 will then extend through the member I in alinement with the longitudinal axis thereof so that the firing pin 23 will be brought into engagement with the central portion of the cap of the cartridge 8. The firing pin engaging end of the firing pin 23 is recessed for the purpose of preventing the firing pin of the rifle from being damaged or mutilated when striking the firing pin 23 for the purpose of exploding the cartridge 8.
From the foregoing description it Will be seen that this device when assembled with a small caliber cartridge therein as shown in Figure 1, may be readily inserted within a rifle designed for a larger caliber cartridge and will her 6 and the member I is then inserted to hold the cartridge 8 in proper seated position. The device is then ready for insertion into the rifle. After the firing of the cartridge 8 the entire device 5 will be ejected from the. rifle in the usual Way, and to again use the device. for another cartridge, the members 6 and 'l are separated and as the member 7 moves out of the member 6, the fired shell is withdrawn from the member 6 due to the flange 2| of the sleeve i8 engaging with the rim. IQ of the cartridge. a slight twisting of the cartridge, the latter may be easily removed from the sleeve 59 and another cartridge placed therein.
If at any time desired, the sleeve It may be omitted by removing the pin which will permit the sleeve is to be withdrawn from the member I. The cartridge may be placed in the member 5 as usual, and the member 1 placed within the member 93, holding the cartridge in a seated position with the sleeve omitted. However, when the sleeve I9 is not employed it is necessary to use asharp instrument to remove the cartridge after being fired from the member 5 and after the removal of the member I from the member 6.
It is believed that the foregoing description,
when taken in connection with the drawing will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.
What I claim is:
l. A supplemental rifle chamber comprising a sleeve-like member providing a chamber for a low powered cartridge, a second member including a reduced portion to extend into the sleevelike member with a slidable frictional fit and provided with a bore extending from end to end, means for releasably securing the members together, and a firing pin slidable in said bore, said second member having a second reduced portion, and a sleeve mounted on said second reduced portion of the second member and projecting beyond the end and provided with an inwardly tapered flange to engage a rim of the cartridge located in the chamber of the sleeve-like rnemher, and a pin connecting the second member with said sleeve.
2. A supplemental rifle chamber comprising a sleeve-like member providing a chamber for a small size caliber cartridge, a second member ineluding a reduced portion to extend into the sleeve-like member with a slidable frictional fit and provided with a bore, means for releasably securing the members together, a firing pin slidable in said bore, and a sleeve mounted on the second member and having an inwardly directed flange at one end to engage over a rim of the cartridge to extract the latter from said chamber on the separation of said members.
