Der- 22, 193 1. J. H. REDFIELD 1,837,290 TELESCOFE SIGHT MOUHTING Filed Dec. 21, 1928


Patented Dec. 22, 1931 128372290 UNITED STATES@ P@ATENT. 0 F@ Ct F I JOHN 33:. REDFIELD, OF DENVM, COLORADO TELESCOPIE SIGHT 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 @rovision of a simple and efficient means which will allow the telescope to be quickly and easily mounted or dismouiited and which will maintain the telescope rigidly in accurate alignment while in use. Anotheir object of the invention is to provide a inountizig which will catise the telescope to always align with a previously determined position when swung to the mounted position so that it will not be necessary to a4'@st"the a i Iignment each time the 15 telescope is mounted. . The invention is designed as an improvement over, and a more siniplified form of, the mounting disclosed in the ai)plicant's copending application, Serial No:275,621 filed 20 May 7, 1928. Other objects and advantages reside in the detail constriietion of tli6 invention, which is designed foi- simplicity, econo , and effl- iri-Y ciency. These will become more apparent 25 froiii the following description. In the following detailed description of the inventioii reference is had to the accom- panyin@, wliieli form a part hereof. Like numeic'als refer to like parts.in all 30 views of the drawihgs'and througliout the description. In the drawings: Fig. 1 is a perspective view illustrating MY improved telescopic mountino- in place upon 35 the receiver of a rifle. 'In thi@'s view the telescope is shown in solid line swung to oiie - side to illustrate the mounting and dismounting action and iii broken line in the mounted position. 40 Fig. 2 is a cross section through the rear mountin- block talcen on the line 2-2, Fig. t, 1, illtistriting tl-ie rear telescope coll@r I in position thereon. Fig. 3 is a similar cross section illustrating 45 the te,,Oscope in the loclced p6sition. Fig. 4 is an elevation of a simplified fotm of the inv@ntion. Fig. 5 is a plan vleiv of the forward mountino, block. 50 .1-i 6 is a bottom view lookina upwardl 9. y at the base of the forward telescope collar. ews of the front inounting block. ve view illustrat-: may be m8unted on t e rear iiiount ng lock, when the telescope is not in use. lli the drawiii-s a sizhiing telescope is I illustrated ai@ 17, and a t@'pical rifle at 9 with its receiver at 11. The invention is more particulai-ly designed to be attached -to the 'u" i- eceiver 11 but can be adapted for attachment to the barrel or other portiolis of the rifle 9. My invention employs a front @mounting block 10 and a rear mounting block 13, both desi-iied to be attached to the receiver 11 by iiieans of pairs of attachinent screws 12 and 14, i- espectively. The front mouiltiiig block 10 co-opei-ates with a front telescope collar 15 and tile rear inotinting block 13 cooperates with a rear telescope collar 16,- to maintain the telescope 17 in place. The forward niotinting block 10 is provided with a cylindri@al concavity in its bot- tom to over the top of the receiver 11. In the upp face of the block 10 a circular de- pression IS is formed haviiig inwardly ex- tendin(r oi- dovetailed sides 19 which open to the sixes of the block 10. Concentrically ar- so i@anoed within the depression 18, is a pivot hole 20. 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 m split, -as indicated at 24, to allow it to be ekpanded to slip over the telescope 17. When in place, the split is clainped together by means of suitable clainp screws 25. The rear mouiiting block 13 is also pro- go vided with a c lindrical concavity in its low. 'er face to fit the contour of the- rifle receiver 11. A wihdage screw 26 is threaded into the block 1.3 at one side and at an angle to the plane of the uppe@. face thereof. The 05 windage screw 26 is pi-ovided with a relatively lai-ge head wliich fits into a counterbare 27 in the block. At the otlier side of the bloclc a clamp screw 28 is hiiia6d upon a hinge pin 29 and prov'ded .@vith a clamp nut 30. The loo


2 1,837,290 rear telescope collar 16 is provided with a base 31 having inwardly- flared sitles. To mount the telescope, the base 21 of the fcirward co.Uar 15 is placed across the front 6 block 10 so that it, drops into the depressi6a 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 10 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 33 until it contacts with the head of the wind- 15 age sc ' rew 26. The atfachment screw 28 is now raised about the hinge pin 29 an d tlle clamp nut 30 is ti(rlitened. This clamps the telescope rigidl@@ rnto s@ghting position with the alignment determined by the position of 20 the windage screw 26. By, relative adjustment of the windage screw 26 aiid the attachment nut 30 the alignment and windage of the telescope 17 can be adjusted. When the alignment and wind- 25 age angle has once been set the telescope can be dismounted and remounied without it bein(-, again necessary to make this adjustment since the screw 26 will always stop the telescope at the proper position. 30 In constructing the device, the counter-. bore 27 should be of a size to f rictionally engage the head of the screw 26 so that this screw can not be accidently -rotated to affect the wiiidage adjustment. Both the screw 26 35 and the clamping nut 30 are provided with coin slots 32 in wiiich a coin can be inserted to assist in rotatino, these memb4rs. The base 31 of tiie rear collar 16 is provided with a transverse groove 33, which pro- 40 vides clearance for the screws 26 and 28 when the telescope is in position. This - roove also provides space for the head of a set screw 34 which clamps the rear collar 16 into position upon the telescope. 45 A sight post 35, such as illustrated in Fig. 8, is provided which can be clamped upon the rear mountin(r block 13 by means of the clamp nit 30. This- allows an ordinary sight disc to be used in place of the telescope 17 when SO 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 cleara-nee for the screws 26 and 28. A tlireaded sight sock- 55 et 38 is provided for the reception of any suiitable siohting disc. A sightin- groove 39 is cut @'ntirely over the front @-nounting block 10 t(> allow the rifle to -be used for ordinar-y sighting without interference by the 80 front mounting block 10. In Fig. 4 I have illustrated an alterna te and more simplified form of the invention. This form is similar to the previously described form except that the hinged attach65 ment screw 28 is climinat6d and in its place a second angularly-placed, windage screw 40 is employect. The second screw 40 coacts with the first wiiidage screw 26 to clamp either the base 31 of the rear telese6pe collar 16 or the post 35 in position. Windage ad- To justn-ient can be obtaiiied by, relative adjust- nient of the screws 26 and 40. The screw 40 is provided with a knurled head 41 to facili- tate its bein(y opei-ated by the fingers to mount and dismount the telescope. In this form Of 75 the invention the screw 40 must be entirely removed to disinouiit the telescope. It is desired to call particular attention to the efficient action of the anlulai-ly I)laced getews 26, 28, tnd 40. This @iigular place- So ment causes the sere-%vs to act both inwardly and downwai-dly so as to firmly lock the tele- scope agaiiist Loth vertical and horizontal movement. While a specific form of the improvement 85 has been described and illustrat@d herein, it is desired to be understood that the same may be varied, Nvithin the se6pe of the appended claims, without departing from the spirit of the iiivention. go I-laviiig thus described the invention, what I claini aild desire secured by Letters Patent is 1.
