J. H. REDFEELD TELESCOPE SIGHT MOUNTING Filed Dec. 21, 1928 Patented Dec. 22, 1931 "JOHN H. RED'FIELD, F DENVER, COLORADO I TELESCOPE sren'r MOUNTING Application filed December 21, 1928. Serial No. 327,494.
This invention relates to means for mounting a telescope upon the barrel of a rifle for sighting purposes and has for its principal object the provision of a simple and efficient means which will allow the telescope to be quickly and easily mounted or dismounted and which will maintain the telescope rigidly in accurate alignment while in use.
Another object of the invention is to provide a mounting which will cause the telescope to always align with a previously determined position when swung to the mounted position so that it will not be necessary to adjust the alignment each time the telescope is mounted.
The invention is designed as an improvement over, and a more simplified. form of, the mounting disclosed in the applicants copending application, Serial N o. 27 5,621 filed May 7,1928.
Other objects and advantages reside in the detail construction of the invention, which is designed for simplicity, econom and efficiency. These will become more apparent from the following description;
In the following detailed description of the invention reference is had to the accompanying drawings which form a part hereof. Like numerals refer to like partsin all views of the drawings'and throughout the description. I
In the drawings:
Fig. 1 is a perspective view illustrating my improved telescopic mounting in place upon the receiver of a rifle. In this view the telescope is shown in solid line swung to one side to illustrate the mounting and dismounting action and in broken line in the mounted position. i
Fig. 2 is a cross section through the rear mounting block taken on the line 2-2, Fig. 1, illustrating the rear telescope collar in position thereon.
Fig. 3 is a similar cross section illustrating the telescope in the locked position.
Fig. 4 is an elevation of a simplified form 1 of the invention.
Fig. 5 is a in block. I, p i Fig. 6 is a bottom view looking upwardly plan viewof the forward mount-' at the base of the forward telescope collar.
Fig. 7 illustrates end viewsof the front telescope collar and front'mounting block.
Fig. 8 is a detail perspective view illustrating a sight disc base which may be-mdunted on the rear mounting block, when the telescope is not in use. a i
1n the drawings a sighting telescope is illustrated at 17 and a typical rifleat 9 with its receiver at 11. The invention is more particularly designed to be attached to the receiver 11 but can be adapted for attachment to the barrel or other portions of the My invention employs a front mounting 65 block 10 and a rear mounting block 13, both designed to be attached to the receiver l1 by means of pairs of attachment screws 12 and 14, respectively. The front mounting block 10 co-operates with a front telescope collar 15 and the rear mounting block 13 cooperates with a rear telescope collar 16," to maintain the telescope 17 in place.
The forward mounting block 10 is provided with a cylindrical concavity in its bote tom to fit over the top of the receiver 11. In the upper face of the block 10 a circular depression 18 is formed having inwardly eX- tending or dovetailed sides 19 which open to the sides of the block 10. Concentrically arranged within the depression 18, is a pivot hole 20. Y
The forward telescope collar 15 carries a base 21 from which extend a pivot stud 22 and a circular dovetail 23. The collar 15 is split, as indicated at 24, to allow it to be expanded to slip over the telescope 17. When in place, the split is clamped together by means of suitable clainp screws 25.
The rear mounting block 13 is also provided with a cylindrical concavity in its lower face to fit the contour of the'rifle receiver 11. A Windage screw 26 is threaded into the block 13 at one side and at an angle to the plane of the upper. face thereof. The
windage screw 26 is provided with a relatively large head which fits into a counterbore27 inthe' block. At the other side of the block a clamp screw 28 is hinged upon a hinge pin 29 and provided with a clamp nut 30. The ion rear telescope collar 16 is provided with a base 31 having inwardly-flared sldes.
To mount the telescope, the base 21 of the forward collar 15 is placed across the front block 10 sothat it drops into the depression 18 with its pivot pin 22 in the pivot hole 20. The telescope is then swung to alignment with the rifle barrel causing the dovetail 23 of the base 21 to enter under the dovetailed sides 19 of the depression 18. As the telescope approaches the position of alignment, the base 31 of the rear collar 16 will slide over the upper surface of. the rear block 13 until it contacts with the head of the windage screw 26. The attachment screw 28 is now raised about the hinge pin 29 and the I clamp nut 30 is tightened. This clamps the telescope rigidl into sighting position with the alignment etermined by the position of the windage screw 26.
By I relative adjustment of the windage screw 26 and the attachment nut 30 the alignment and windage of the telescope 17 can be adjusted. When the alignment and windage angle has once been set the telescope can be dismounted and remounted without it being again necessary to make this adjustment since the screw 26 will always stop the telescope at the proper position.
In constructing the device, the counter-, bore 27 should be of a size to frictionally engage the head of the screw 26 so that this screw can not be accidently rotated to affect the windage adjustment. Both the screw 26 and the clamping nut 30 are provided with coin slots 32 in Which a coin can be inserted to assist in rotating these members.
The base 31 of the rear collar 16 is provided with a transverse groove 33, which provides clearance for the screws 26 and 28 when the telescope is in position. This groove also provides space for the head of a set screw 34 which clamps the rear collar 16 into position upon the telescope.
A sight post 35, such as illustrated in Fig. 8, is provided which can be clamped upon the rear mounting block 13 by means of the clamp nut 30. This allows an ordinary sight disc to be used in place of the telescope 17 when desired. The sight disc block 35 is provided with a dovetailed base 36 to receive the nut 30 and the head of the screw 26, and with a bottom groove 37 to provide clearance for the screws 26 and 28. A threaded sight socket 38 is provided for the reception of any suitable sighting disc. A sighting groove 39 is out entirely over the front mounting block 10 to allow the rifle to 'be used for ordinary sighting without interference by the front mounting block 10.
In Fig. 4 I have illustrated an alternate and more simplified form'of the invention. This form is similar to the previously described form except that the hinged attachment screw 28 is eliminated and in its place either the base 31 of the rear telescope collar 16 or the post 35 in position. \Vindage adjustment can be obtained by relative adjust ment of the screws 26 and 4.0. The screw 40 is provided with a knurled head 41 to facilitate its being operated by the fingers to mount and dismount the telescope. In this form of the invention the screw 10 must be entirely removed to dismount the telescope.
It is desired to call-particular attention to the eflicient action of the angularly placed screws 26, 28, and 4:0. This angular placement causes the screws to act both inwardly and downwardly so as to firmly lock the telescope against both vertical and horizontal movement.
While a specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the appended claims, without departing from the spirit of the invention.
Having thus described the invention, what I claim and desire secured by Letters Patent 1.
