UNITED STALSjLATENT OFFICE. FREDERICK L. SMITH, or oHIooP E FALLS, MASSACHUSETTS RIFLE-TELESCOPE. I

Be it known that I, FREDERICK L. SMITH, a citizen of the United States, residing at Ohioopee Falls, in the county of Hampden and State of Massachusetts, have invented new and useful Im rovements inRifle-Telescopes, of which the ollowing is a specification.

This invention relates to telescope-mountings for firearms, the object of the invention being to provide a telescope adapted for use on take down guns, so called, whereby when the gun is put together the telescope ma be movedinto' roper position for use an when the barre is removed from the stock the position of the telescope may be shifted to adapt it to fit the gun-case in the place therein provided for the barrel or to be packed for transportation in any space which as to length will receive the barrel.

Having these ends in view, the invention conslsts in mounting the telescope solely upon T the barrel in fixtures'or mountings which will permitit to slide longitudinally and at the same time permit the vertical and horizontal adjustment of one end thereof to si htthe gun.

In the drawings forming part 0 this application, Figure 1 is a side elevation of a rifle-b arrel dismounted from its stock and havin a telescope mounted'thereon according to t s invention. Fig.'2is a similar view to Fig. 1, showing a rifle-barrel mounted in the stock and showing the telescope in another position: Fig. 3 is a top plan view of a portion of the rifle-barrelland the telescope shown in Fig. 2. Fig. 4 is a sectional elevation on line 4, 4, Fig. 1. Fig. 5 is a to plan view of the telesco e-mounting locate at the breech end of the arrel. Fig. 6 is asectional elevation on line-6'6, Fig. '2. Fig. 7 is a'longitudinal 'sectional elevation on line 7 7, Fig. 3, show-' mg the construction of the muzzle end of the te e scope and its'front mounting. s. 4, 5,

6, and 7 are on a somewhat larger sca e thanthe other figures.

In the use of telescopic sights in rifle-shoot;

to the receiver at one end and on the barrel,

near the muzzle, atthe other end. This is not only a serious inconvenience v when it is desired to transport the gun its case, for it necessitates dismounting the telesco e if the gun is of the take-down type, who opera- V Specification of Letters Patent.

7 tion necessarily disturbs the adjustment of the telescope and necessitates resi hting the rifle when the parts are again assembled; but, furthermore, the mounting of one end of these telescopes on the receiver or stock and the other end on t e barrel of the arm renders it much more di cult to maintain the accurate adjustment thereof than if the telescope be mounted entirely upon the barrel, as in this invention. construct a telescope a, adapted to be mount ed entirely upon the barrela" in suitable fixtures or mountings, of which 1) represents that one located near the muzzle of the rifle, and c that one located near the breech thereof. While in the drawings these mountings are shown as secured to the top of the barrel, they may,,=if desired, be secured on one side or the other'of the barrel, it being the preference of some to have the telescope mounted at one side of the barrel in order that the ordinary sights of the latter: need not be removed This is a matter, however, which does not concern the invention, it being merely a question as to the location of the parts which constitute the invention. i The front mounting 12 comprises an annu- To overcome'these'objections, I I

lar member of larger diameter internally than a the exterior diameter of the telescope, which member is'mounted upon a block d, which is screwed or otherwise secured to the barrel. A plun er eis located in the block (1, its upper en passing through a hole and into the annular member of the mounting, a suitable spring f forcing the plunger radlally toward the center of the mounting to the end that the forward end of the telescope when located in said mounting will by means of said plunger be pressed normally against the upper side of said annular member, whereby the axis of the telescope in the front mount- 'ing may be located at a fixed distance from v This construction will e to be the axis of the barrel.

a manner to be hereinafter described to proption it is moved forward to the position shown in Fig. 1.

As shown in' Fig. 6, the telescope is provided with theusual cross-hairs g, whose intersection islocated inthe axis of the telescope, and which hairs to insure accuracy in aiming should. be located, respectively, in

'Fig. 2, and to that end the upper forward edge of the mounting b is notched, as shown in Fig. 3, and a pin or screw, as h, secured to the telescope in position of alineinent with 1 one of the cross-hairs g and is adapted to engage the converging sides ofthe notch cut in the mounting, and thus center the telescope and locate said cross-hairs in proper position. i

In the construction shown herein the screw his used to constitute a limiting-stop for the telescope, and this screw is the one by which the tubular slide i is secured in the tube of the telescope, this tube carrying the posterior objective-lens 7'. (Shown only in dotted lines in Fig. 7.) The movement of this tube 11 toward and from the rear end of the telescope effects the focusing of the latter, the body of the telescope having a longitudinal slot lc therein to permit the adjusting movement of I i said tube 71, which is effected by loosening the screw h and moving the tube forward or back until the proper focus is reached, then tightening up the screw. Obviously any other projection located on thetelescope in a position to enga e the notch in the mounting-b may be use instead of the adjusting-screw h. The rear mounting 0 also comprises an annular member mounted upon the block m, properly secured to the barrel, and said annular member is also provided with a plunger n, which by a spring 0 is normally forced.

toward the center of the mounting. This spring-pressed plunger, however, on the rear mounting is located at an angle of forty-five degrees one side or the-other below the center thereof, and two adjusting-screws are located in the mounting, one vertically and the other horizontally, the horizontal screw beingon that side of the mountin -o posite to that on which the springressed piiingero-is located, thus providing t e rear end of the telescope with a thre'e-pointbearing tllie presses the tu e of the telesco eequa I; against the other two points of t e bearing. T e vertically-located adjustin -screw is indicated by p and the honzontad screw by 9.;

As the vertical adjustment of the rearend of the telescope must b greater than-the horizontal adjustment th eof, the inner-endof the horizontal screwg is provided with a head 1 larger than the screw,to the end, that this head may afford a suitable bearing forthe telescope, where the pivotal adjustment l thereof might otherwise carry it so far as to permit it to slide off of the end of the screw. i To provide a convenientlocking for the ad= i justingscrcws 7) and q, the rear mounting is slotted, as at s, a screw t being located trans versely of the slot, whereby after the adjusting-screw has been .set the screw t may be turned up to lock them in their adjusted posi- 1 tion.

! From the foregoing description it is seen i that the telescope may be moved in its mountings toa position shown in Fig. 1, which will permit it to be packed in a space no longer E than that required for the barrel and-when i the latter is mounted on its stock drawn back intoa position which permits the a plication of the eye close to the rear end 0 g the telescope and that this sliding movement may "be effected without disarrangement of the adjustments of the telescope, and'therefore a from the stock at will and mounted again and be ready for use without resighting. This is of great utility in this class of rifles, as

tion.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

down rifle, of a telescope mounted thereon provided with suitable horizontal and vertically -disposed cross-hairs, suitable mounts for the telescope located near each end of the barrel and in which the telescope is longitudinally slidable, a stop on the telescope to engage one of said mountings to prevent the rovertical an horizontal adjustment of thetelescope.
