GUN-SIGHT.

SPEGIFIGATION fOrming part of Letters Patent N0. 753,505, dated March 1, 1904. Application filed ctobe1 30,1903. Serial No. 179,186. (No model.)

of Pennsylvania, have invented certain new and useful Improvements in Gun-Sights, of

which the following is a specification.

This invention comprises improvements in mechanism for sighting guns. I

One object of the invention-is to provide an elastic mounting for the telescope or other sights of the gun to prevent shock or injury to the eye of the gunner dueto the recoil of the gun. I r I 1 Another object of the invention is to provide for using several sights with a minimum opening in the shield of the gun.

Other objects are to improve the general construction of this class of devices.

The invention will be described in connection with the accompanying drawings, in which I Figure 1 is a sideview of a portion of a gun provided with our improvements. Fig.2 is an enlarged plan view of the sighting device shown in Fig. 1, parts being broken away. Fig. 3 is an enlarged side view of the sighting device, partly in section. Fig. 4 is a rear view of the same. Fig. 5 is a sectionalview of the eyepiece of the open sight. .Fig. 6 is a section on the line 6 6 of Fig. 4. Fig. 7 is asection on the line 7 7 of Fig. 6. Figs. 8, 9, and 10 are details of the pinions used in adjusting the sights. Fig. 11 is a rear view of the shield. Fig. 12 shows the sights mounted directly upon the gun. Fig. 13 is a detail of Fig. 12; and Fig. 14 is a section similar to Fig. 6, butshowing a different clamping arrangement."

Referring to the drawings, 1 indicates a gun; 1, the tube or cradle in which it recoils; 2, the upper part of the mount, and 3 the shield.

Supported upon and movable with the gun or cradle is a tube 4, which carries the telescope 5 and the open sights 6 7 As shown in Figs. 1 and 4, the sights are mounted on the cradle,while in Figs; 13 and 14 they are mounted directly upon the gun.

Referring to Figs. 1 to 12, inclusive, the

tube 4 is connected near its forward end with the gun by a suitable universal joint 8 and bracket 38, which permits of the rear end of the tube being elevated or depressed or moved laterally with respect to the gun. scope 5 is removably mounted inarms 9 10 of a bracket 11. The arm 10 is free to slide upon the tube 4. The arm 9 is rigidly connected to the rear end of a rod 12, which slides in the tube 4. The forward end of this 'rod is provided with a head 13, which carries the for- Ward open sight 7 Within the tube 4 and surrounding the rod 12 is a coiled spring 14, one end of which bears against a shoulder 15 on the. rear end of the rod, while the other end of the spring bears against a shoulder or projection 16 on the inside of the forward end of the tube 4. The rear end of the tube 4 is screwed into a head 17, in which the enlarged rear end of the rod 12 slides. The forward telescope-supporting bracket 10 slides on the tube 4 and is normally held against the head 17 by,pressure of the spring 14. It will be apparent that the tube 4 receives a shock from the gun in firing andthat the telescope and open sights are permitted to have yielding forward movementsrelatively to the gun during the firing and that they will be returned to their normal positions by the spring 14.

The rod 12 is free to turn within the tube 4 when pushed forward against the spring for the purpose of bringing the telescope and the open sights alternately into operative position. In Fig. 4 the telescope is shown in full lines inoperative position, being central with respect to the opening 18 in the shield 3, and it is shown in dotted lines rotated to the right, which brings the open sight 6 into operative position. The telescope is locked in either of these positions by means of a series of recesses 19 in the bracket 10, which cooperate with a series of ribs 20 on the tube 4. By

pushing the bracket forward it is disengaged from ribs and may turn, and on releasing it the spring 14 reengages it with the ribs, and the telescope is thus locked in position. The ribs and recesses are sufliciently long to permit of the cushioning action of the sights during the recoiling of the gun.

The head 17 has an undercut groove in its under side in which the upper end 21 of the elevating-rack 22 has a sliding engagement. To aline the telescope with the vertical plane of movement of the gun, the head 17 is movable laterally with respect to the rack 22, this adjustment being effected by thumbscrews 23. An index-point 24 and scale 25 are preferably used to indicate the exact positions of the sights with respect to the axis of the gun. By means of the adjusting-screws 23 the sights may be set to any desired angle to be read off the scale to correct deflection of the projectile by wind, &c.

To elevate the gun to any desired angle, the elevating-rack is raised until the sights are elevated to the proper angle. The rack is then looked in this position, and on bringing the telescope back to horizontal position by moving the gun the gun will be elevated as desired. The rack is preferably operated by means of a pinion 43, shaft 44, wormwheel 45, and worm 26. The worm 26 is mounted on shaft 27, which is provided with a hand-wheel 28 on one end and a second wheel 29 on' the other end. Integral with the second wheel is a brake-wheel 30. The brake-wheel and handwheel are arranged to slide on and turn with the shaft 27. The brake-wheel is normally pushed out into position to engage the brake 31 by a spring 32. The brake 31 is in the form of a lever, which is held in position between the screw 33 and the spring 34. By adjusting the screw 33 the position of the brake may be changed. When it is desired to shift the rack 22, the handwheel 29 is pushed in to relieve it from the friction of the brake and then turned until the rack is in the desired position. On releasing the wheel the brake-wheel' is forced out by the spring 32 against the brake 31, and thus locked in position. The wheel 30 is preferably provided with a roughened surface.

In Fig. 14 is shown another clamping arrangement that may be used instead of the one just mentioned. The worm 26 is mounted and keyed to shaft 27, which is provided with hand-

wheels

28 and 29, and the shaft 27 is allowed a slight longitudinal movement in its bearings and also in the worm 26. 47 is a collar screwed into the bracket 36, and the adjoining faces of said collar and wheel 29 are toothed at 47, so as to engage when the shaft 27 is pushed forward by the spring '48, and thus locking the sight-gear. To operate this gear, the wheel 29will have to be drawn out or the wheel 28 to be pushed in till the teeth 47 disengage, when the hand-wheels will turn freely. On releasing the hand-wheels the spring pushes the shaft forward and locks the gear.

The rack 22 is provided with a scale 35. The bracket 36, in which the rack-operating parts are mounted, has a sight-opening and an index 37. The indexes 24 and 37 are slightly adjustable to compensate for any errors in mounting the

brackets

36 and 38 on the gun or cradle. As shown, the universal joint 8 connects the tube 4 with a bracket 38.

To prevent any lost motion between the worm-wheel 26 and the rack 22, we preferably make the worm-wheel '45 and the pinion 43 each in two parts, which parts are under a spring tension to move in opposite directions. This construction is shown in Figs. 8, 9, and 10, in which thesprings 39 tend to shift the gear-teeth relatively. This construction of split gear is not new and need not be further described herein.

In the eyepiece of the open sight 6 is an adjustable disk 40, having a central sight-opening 41, which is held in position by an internal screw-collar 42. This disk is adjustable in order to aline the open sights with the telescope, thus avoiding any adjustment of the mountings of the open sights or telescope.

Referring to Figs. 12 and 13, it will be seen that the supports for the sights are mounted directly upon the gun 1 instead of being fixed to the cradle or gun-mount. In such case we prefer to connect the sights with the cradle or some other relatively stationary portion of the gun-mount to prevent the sights from recoiling with the gun, and thus diminish the shock to theeye of the gunner. As shown in Figs. 12 and 13, the rod 12, to which the sights are connected, is connected at its forward end with a stud or bracket upon the cradle 1 by a link 51. The link 51 and rod 12 are connected by a universal joint 52 of suitable construction, and the link 51 is connected with the bracket 50 by a pin-and-slot connection 53, which permits the rod 12 to have the traversing and elevating adjustments previously described and also to turn upon its axis. The slot also permits of aslight recoil movement of the sights. When the gun recoils, the

brackets

36 and 38 go with it; but the link 51 only allows the rod 12 to recoil a short distance-say a fraction of an inchwhile the remaining movement of the gun compresses spring 14. Instead of the link 51 a chain or other connection may be used, which will prevent recoil of the sights and permit of the necessary adjustments of their support.

When the sights are carried directly by the cradle or gun-mount, their relation to the gun may vary if the gun is not accurately adjusted in its cradle. For this reason it is preferable to attach-the sights; directly to the gun, and

we have rendered this practicable by connecting the sights when so mountedwith a relatively stationary part of the apparatus, such as the cradle.

It will be evident that many changes in details of construction may be eifected without materially departing from the spirit and scope of our invention.

Therefore, without limiting ourselves to the precise construction and arrangement of parts illustrated and described, we claim 1. The combination with a gun, and a shield havinga sight-opening, of a plurality of sighting devices suitably supported and each movable into and out of alinement with the sightopening of the shield.
