United States Patent OPTIONAL GUN SIGHT RETICULE ENLARGING DEVICE I Richard L. Oswald, Los Angeles, Calif. Application November 5, 1953, Serial No. 390,313
6 Claims. (CI. 33-50 This invention relates to gun sights and has particular reference to telescopic gun sights. Rifle telescopic sights of the conventional type are used both in target practice and in the field. These telescope sights are usually equipped with reticules having horizontal and vertical cross-hairs. Reticules that cover a minute of angle or less are preferred. for accurate sighting and are entirely satisfactory in target practice where light conditions are uniformly good and the gunner can move slowly to aim his rifle. There are times, however, particularly in hunting, where light conditions are poor and frequently the target is moving so rapidly that instantaneous sighting is imperative. Under such conditions it is well high impossible to find time not only to move the rifle into aiming position but also for the eye to find the 'cente of the very fine reticule.
It is in view of the foregoing the object of the present invention to provide a device for instantly changing the size of a telescopic sight reticule center when such on favorable conditions are encountered. A further object is to provide-a device which normally is held in a retracted out-of-the-way position, but which may be'quickly moved into operative position more clearly to define the reticule center.
These and other objects of the invention, as well as the many advantageous features thereof, will become apparent upon perusal of the fo'llowing detailed description and by referring to the accompanying drawing in which a preferred form of the invention is illustrated In the drawings:
'Fig. 1 is a cross-sectional view of a portion of a gun sight telescope tube within which the device of the invention is mounted;
Fig. 2 shows, on a larger scale, the manner in which operating elements of the device are mounted on the tube;
Fig. 3 is an end view of the parts shown in Fig. 2;
Figs. 4 and 5 show other parts of the device;
Figs. 6 and 7 illustrate a modified manner of operating the device of the invention; and
Figs. 8 and 9 show a further modification thereof;
The device of the invention is in any suitable manner mounted within a conventional telescope sight, a portion of the tubular casing of which is indicated at 1.
The reticule '3 of the telescope sight is mounted within a reticule support 4 which in any conventional manner,
not shown, is mounted for adjustment correctly to de-- fine the line of sight of the telescope. The wall of the 'reticule supportis in the drawing shown extended to provide an anchoring place 5 for .a lever 6. j The latter is shown hung on a pivot 7 for oscillating movement within a slot 8 of the support to swing the lever into the full outline position of Fig. 4 as close as possible to and parallel with the vertical strand 9 of the reticule.
The lever terminates at the bot-tom in a circular disk 10 forming a head which may be termed a dot reticule, the center of which takes a position in axial alinement with the reticle center when the lever is swung into the "ice full line position and it is merely large enough in diameter to be more clearly visible to the gunner than the intersection of the hue cross-hairs when the rifle is swung into aiming position. The lever is in 'Fig. 5 at 11, for the purpose of strength, shown wider at the pivotal point thereof and downwardly tapering to terminate in a line line next to the head 10. I
The other end of the lever is by a rod .1 5 connected with a plate 16 which, in turn, is seated for lengthwise sliding movement within the wall of the telescope tube. This plate is by a spacer 1-7 connected with a fingerpiece, or shoe 18 which may be manually moved along the surface of the telescope tube to operate the lever. The length of the opening through the tube wall, in which the spacer 17 is seated, should be calculated to provide the spacer sufii-cient movement to swing the lever -from one position to the other. The exact :arc of travel of the lever is determined by the surfaces 12, 13 of the slot 8.. It is also advisable to mount a soft, compressible pad 19 below the finger-piece 18 in order to provide a light and air-tight joint between this slide assembly andt-he telescope tube.
It is seen from the foregoing description that I have provided a very simple reticule center enlarging device which may beembodied in conventional reticule equipped telescopic gun sights in such convenient manner that it may be instantly brought into service by a simple movement of a :fi-nge-r. And While the above described method of actuating the reticule lever is found preferable in most cases it may at times be found convenient to substitute arotating movement for the sliding movement of the finger-piece 18. This modification is illustrated in Figs. 6 and 7 of the drawings.
A plate 20, somewhat similar to plate 16, is mounted for sliding movement withinthe telescope tube 23 and it 'is, like plate 16, made with a projection 21 seated in a slot 22 of the tube. A sleeve 24 is mounted for rotation-on the tube between fixed collars 25, 26 and a hole 27 is cut-through this sleeve of a size to receive therein a screw 28. The threaded shank of this screw engages the threads of a socket 29 of the plate projection 21 to maintainthe plate in position againstthe inner surface of the tube. The sleeve is at 30 shown internallyirecessed to form a helical groove extending from the hole 27 about one-half the distance around the inner surface of the tube. A boss 31 projects inwardly from one end of the plate 20 and this boss is shown perforated to receive one end of the connecting rod 15. Rotation of this sleeve, within the limits of the helical groove 30, will impart suflicient axial movement to the plate 20 to swing the lever 6 on its pivot for the purpose above described. The joints between the sleeve and the collars 25, 26 may be sealed by means of gaskets 32, 33 and the entrance to the hole 27 of the sleeve may be plugged as indicated at 34 to prevent penetration of air and light into the tube.
In other cases, it may be found preferable directly to connect the reticule lever for manual rotation and such combination is illustrated in Figs. 8 land 9 of the drawings. The pivot'7. of the lever is in this case shown extended to form a shaft 40 which extends through the wall 31 of the telescope tube and a knob 32 is fastened to the outer end of this shaft. Manual rotation of this shaft will swing thelever into and out of operative position. A hearing bracket 43 is shown mounted on the tube for extension of the shaft 40 therethrough land a gasket '44 is placed below this bracket to provide a light and airtight seal. The outer opening of the bracket may be tightly sealed by means of gaskets 45, 46 which by a bushing 47 are held tightly compressed.
The above description, in connection with the illustrations in the drawings should be suflicient to enable anyone versed in the art to construct a complete operative device including the invention. But while I 'have illustrated and described preferred forms of the invention I do not intend thereby to be limited to the arrangements and proportions exactly as shown but reserve the right to embody modifications thereof within the scope of the claims hereto appended.
