TELESCOPIC SIGHT FOR GUNS.

Specification of Letters Patent.

Patented April 24, 1906.

Application filed October 26, 1.903. Serial No. 178,625.

' JAKoBssoN, a subject of the King of Sweden and Norway, residing at South Bethlehem, Northampton county, Pennsylvania, have invented certain new and useful Improvements in Telescopic Sights for Guns, of which the following is a specification.

The object of our invention is to relieve the shock to the head of the person sighting a gun which occurs in firing the same when the gun is provided with a telescope used for sighting, and to this end the telescope is provided with yielding sections, whereby a part connected with the gun or gun-cradle may move back without necessarily carrying with it the section supporting the eyepiece, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a telescope as mounted upon a bracket connected with a gun or gun-cradle. Fig. 2 is a longitudinal section of the telescope. Figs. 3 and 4 are detached sectional views of the parts of the telescope-tube. Fig. 5 is a rear view of part of the mounting. Fig. 6 is a section on the line 6 6 of Fig. 2.

The telescope is supported on and slides in a suitable bracket or support O, and the section F of the telescope is longitudinally adjustable through the medium of a worm-rack 10, engaging a worm 12 on a shaft having its bearings in a suitable support. This serves to carry the telescope longitudinally and to ,hold it in the position to which it is adjusted.

The object of this bodily adjustment is to suit the position of the telescope to different gunners.

The tubular part E, which slides in the part F, has longitudinal slots 5 at its forward end, which receive longitudinal ribs 7 (see Fig. 3) a short distance from the rear end of the part F, which permits the part E to slide back and forward a limited distance in the part F without turning. A spider K in the tube Eat the rear of the ribs 7 has projections which enter the shorter slots 4, extending back from the forward end of the part E, and

bear against the ends of these slots 4 under the action of a coiled spring L, which bears against the spider and also against a ring 6 inside the forward end'of the part F, which is prolonged in the shape of a tube or barrel 9, carrying the object-lens 19 at its forward end. The part or section E has an annular shoulder 20, which abuts against a screwring 21 on the part or section F and limits the rearward motion of the part E.

If when the gun is fired the face of the gunner bears against the eyepiece of the telescope, the sudden shock of the gun or cradle carrying the main barrel of the telescope will not necessarily be communicated to the section or part E and there will be no severe pressure against the face of the unner, the spring L yielding during the shoc k to permit the section E to remain practically stationary, but at once restoring the section E to its normal position in respect to the other part of the instrument, so that the lenses will occupy the proper position in respect to each other. In order to further prevent any injury to the gunner, we apply a yielding pad H, of rubber or other suitable yielding material, to the eyepiece end of the instrument, and thus reduce the effect of a blow in case the gun should be fired when the face of the operator is not in contact with the end of the telescope.

Without'limiting ourselves to the precise construction and arrangement of parts shown, we claim as our invention 1. The combination in a telescope, of two sections having corresponding longitudinal ribs and recesses, additlonal shorter recesses in the rear section, a spider having projections extending into said shorter recesses, and a spring bearing against said spider and against a bearing in the forward section of the telescope, substantially as set forth.

2. The combination with a gun, of a telescope, a support for the telescope mounted on the gun or guncradle, and means for ad justing the telescope longitudinally in said su port and securing it after adjustment, the tel scope being in sections, one' sliding in respect to the other, with an intervening spring, substantially as set forth.

3. The combination with a gun, of a telenames to this specification in the presence of scope, a support for the telescope mounted two subscribing Witnesses.
