H. v. DOE TELESCOPE MOUNTING Filed Aug. 9, 1953 FHCAL UJSTEUMENTQ.

Patented Sept. 18, 1934 UNITED STATES PATENT OFFICE 4 Claims.

i jmeans for adjusting the telescope, and for taking care of the recoil.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing:

Fig. 1 shows in side elevation, a device constructed in accordance with the invention;

Fig. 2 is a vertical longitudinal section on an enlarged scale, parts being broken away, and parts being shown in section;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a section on the line 4-4 of Fig. 2;

Figs. 5 and 6 are sectional views showing a modification.

The numeral 1 indicates a firearm, such as a gun, including a barrel 2.

A rear support 3 is provided and is equipped at its upper end with a vertically elongated loop 4. At the bottom of the support 3 there are arms 5, having some resiliency, but adapted to embrace the barrel 2 of the firearm 1 closely. At their lower ends, the arms 5 have downwardly extended ears 6, connected by a tightening screw 7. The screw 7 may be tightened up to hold the rear support 3 firmly on the barrel 2, but to aid in holding the support in place on the barrel 2, and take some of the strain off the tightening screw 7, a set screw 8 is threaded into one of the arms 5, the set screw being adapted to engage one side of the barrel. The rear support 3 has an opening 9. A sight plate 10 is dove-tailed for sliding movement into the rear side of the support 3 and extends across the opening 9. The sight plate 10 is tightly fitted in its slot, of course, so that it can be moved only by considerable effort. In the sight plate 10 there is an opening 11 exposing the front sight 12 on the barrel 2.

A telescope 14'fits against lateral movement in the loop 4 but has a vertical movement for adjustment in the loop. A bowed spring 15 is secured intermediate its ends to the rear support 3, and bears upwardly at its ends upon the tube of the telescope 14. On top of the telescope 14 is located a curved saddle 16 which conforms to the curvature of the telescope and fits within the loop 4. On one side, the saddle 16 has a laterally projecting finger 17 vertically adjustable in the slot 18 formed in one side of the loop 4. On the top of the saddle 16, there is a projection 19, adapted to be received in a recess 20 formed in the lower end of a screw 21 threaded into the top of the loop 4.

The front support is marked by the numeral 22 and has arms 23, possessing some resiliency, and extending tightly around the barrel 2. On the lower ends of the arms 23 are ears 24, connected by a tightening screw 25, and, thus, the front support 22 is held tightly on the barrel 2 of the firearm 1. A set screw 26 is threaded into one of the arms 23 and bears against the barrel 2. This set screw 26 aids in taking some of the strain oif the set screw 25.

On its upper end, the front support 22 is arched as shown at 27, to expose the front sight 12, as shown in Fig. 3. The arching at 27 forms upwardly projecting arms 28 in which an adjusting screw 29 is held for rotation, but against longitudinal movement. The adjusting screw 29 is threaded on a projection 30, depending from a carrier 31, in the form of a ring, receiving the telescope 14. The forward end. of a bowed spring 33 is secured to the bottom of, the ring or carrier 31 and extends rearwardly. The spring 33 exerts an upward pressure on the telescope 14. A projection, such as a screw 32, is threaded into the top of the telescope 14. The projection or screw 32 has limited movement in an opening 34 formed in the top of the ring or carrier 31.

The rear end of the telescope 14 may be adjusted vertically, by moving vertically thtTscrew 21 which is--threadedfiiltothe top of the loop 4 of the rear support 3. The saddle 16 follows the screw 21, up and down, under the action of the spring 15, which exerts an upward pressure on the telescope 14. Thus, a vertical adjustment of the telescope 14 can be effected. During the vertical adjustment of the telescope, the projection 30 on the carrier ring 31 moves or pivots on the screw 29, this pivoting movement producing no lateral movement in the forward end of the telescope 14, which amounts to anything. The telescope 14 can be adjusted later-.2110

ally, at its forward end, by turning the screw 29, that screw being threaded into the part 30 of the ring 31 which carries the telescope 14.

In the event of a recoil, the forward end of the telescope has a slight longitudinal movement with respect to the ring 31, because the opening 34 in the ring, which receives the projection or screw 32 in the telescope 14 is slightly larger in diameter than that screw.

The device is simple in construction and it afiords a means whereby a telescope may be mounted simply but securely on the barrel of a rifle, the necessary adjustments in the telescope being efiected.

In Figs. 5 and 6, parts hereinbefore described are designated by numerals previously used, with the suffix a. The clamping means 2425 and 67 of Figs. 3 and 4 are dispensed with, and the parts 5 and 23 are replaced by solid rings 35 that have a close fit on the gun barrel 2, the set screws 8a and 26a being engaged in recesses or punch marks in the barrel 2. Some barrels, similar to the Krag, some Winchesters, Remingtons etc., have the front sight made integral with the barrel, hence the divided members 5 and 23 of Figs. 3 and 4. However, in barrels similar to the Springfield, the front sight is provided with a sleeve, enabling the sight to be easily removed. In such cases, the rings 35 can be used, since by removing the sleeve, the devices shown in Figs. 5 and 6 can be slipped on the barrel, and the set screws 8a and 26a tightened. Enough metal is incorporated in the rings 35 at the time of manufacture, so that, if the barrel 2 happens to be a little too large in diameter, the openings of the rings can be enlarged slightly, with a file or reamer, thereby permitting the rings to be placed on the barrel, at exactly the position desired by the operator, longitudinally of the barrel.
