TRAINING DEVICE Fon GUNS.- 'i

SPECIFICATION forming part of Letters Patent No. 772,248, dated October 11, 1904. v Application filed June 11, 1902. Renewed March 15,1904. Serial No. 198,323. (N model.)

To all whom it may concern.-

Be it known that I, SAMUEL N. MCCLEAN, a

citizen of the United States, residing at Cleveland, Ohio, have invented a new and useful Improvement in Training Devices 'for "funs, which invention is fully set forth n t :yf following specification.

My invention relates to guns and gun-car'- riages, and more particularly to a devicey for eiecting the elevating, depressing, traversing, and general training movements of the gun.`

Broadly stated, the object of the invention is to providea device whereby all the movements involved in training the gun may be effected by a single operating device, to the end that said device may impart any desired movement to the gun in sighting it within a given radius or tield of action to cause it to move along any desired line or to any desired point on the target at which it may be aimed, whether said target be a iixed or a moving one.

With this object in View the invention consists in a gun and its mount which leaves the gun free to receive theusual training movements, with a pair of reciprocatory members or supports for thebree'ch of the gun, which members or supports are so mounted as to be capable of oscillation as well as reciprocation. ports are attached to the breech of the gun or to the cradle supporting the gun, on opposite sides thereof, xby means of some flexible joint, as a universal joint, and are provided with a bearing on the gun-carriage, platform, or other base, which bearing leaves the mem.- bers or supports free to receive reciprocatory and oscillatory movements. In order to secure the benefits of the invention in the highest degree, this bearing for the members or supports is in the nature of a universal joint through which the member or support-reciprocates.

The inventive idea linvolved may receive various mechanical expressions, the preferred form being one in which the gun is mounted in a cradle which is free toturn around a universal joint in order that within prescribed limits it may receive any desired movement or' elevation, depression, or training. At-

Preferably these two members or sup-- tached to the opposite sides of this cradle, near the rear end thereof,.are the two members or supports'in the form of screws vwhich pass through nuts which are operable to impart the reciprocatory movements to the screw, while at the same time leaving it free to oscillate.

In the drawings forming a part of this specilication, Figure 'l is a broken side elevation of a field-gun and carriage having my invention applied thereto. Fig. 2 is a broken plan, and Fig. 3 is a horizontal section, of the universal joint around which the cradle moves. Figs. 4 and-5 are part-sectional part-elevational detail views showing the manner of mounting and operating the supports or members. Figs. 6 and 7 are views illustrating a modification.

Referring to the drawings, 1 is the axle of a gun-carriage, and v2 2 are twin members of a boxing on the axle, each of which members is provided with aconcave face fitting the axle and a hemispherical portion 3. `lVhen said members 2 2 are assembled around the axle and retained in positiony by collars 4. 4, they form the spherical part of a'universal' joint around y which the gun-cradle 5 may move, the cradle haring the concave member ot such joint formed therein, as "shown in Figs. 2 and 3, such concave member being cut away, as at 6 6, to permit the free turning movement of the cradle around the spherical parts 3 3. In assembling the parts the members 2 2 are slipped into the'boxing in the cradle and Apushed into position opposite each other, af-

ter which the axle is inserted and the collars 4 4. secured in place on the axle. The carnage has any suitable trail-cheeks, one of which is shown in broken elevation in Fig. l asatube 7. There are two of these trail-cheeks, two supporting-screws, and operating parts therefor, and as they are similar in ali'respects a description for one will sulice for` both. A. screw 8 is jointed to an ear 9 so as to vmove ina transverse plane, said ear being mounted to turn and slide in a dovetailed groove l() in the side of the cradle 5. A nut 1l in the form of a beveled gear is mounted on the screw '8 and is engaged by asecond beveled gear 12,'

mounted on a sleeve 13 4on the cheek 7 and.y

i anges 21 on-the bracket 22.-

/ to be assembled and disassembled.

' said bracket and the bearing 18. passes through the bearing 18, and the latter operated b va wheel 14, the whole being secured in position by a collar around the cheek. Looselysurrounding the sleeve 13, between the'whee'l 111 and the gear 12, is a sleeve 16, supporting guide-brackets 17 17, through which the screw passes and by which it is guided. The nut 11 rests on a bearing 18, shaped to conform to the cheek 7 and moving around it, one of the` guide-brackets`17 lying above the nut, so as to retain it between The screw moves with the screw as it oscillates. The same is true of the guide-brackets 17 17.'

Amoditication ofthe device is lshown in Figs. 6 and 7, in which the supporting-screws are connected to the cradle by a ball-and- .y socket joint 19 and are connected to the cheek ofthe trail by a band having flanges 20, formed, as shown in Fig. 7, to engage corresponding These iianges 20 and 21 are" cut away to permit the parts to be turned beyond their working point and The gears for operating this form of the device are similar to those previously described, and the operating hand-wheel is located on the side of the trail-cheek. instead of surrounding thel If it is desired simply to-elevate orsdepress the gun, the hand-wheels4 14C on yeach cheek ofv the trail are operated in the saine direction, thereby serving to run the screws 8 8 up or down, 'as the case may be, and `for thispurpose-only the reciprocatory movements are necessary. 1f it is desired to traverse the gun-muzzle, say, to the right, this may be accompiished byv running the right hand screw up or the left-hand screw down or by simultaneously running the right-hand screw up and the left-hand one down. v`lin short, by simultaneously operating the two hand-wheels at the same or varying rates of speed and in the same or reverse directions the muzzle of the gun may be caused to follow any desired line, andv with a little practice in its manipulation it becomes possible to readily follow a moving target and keep the gun laid thereon at all times. During the up-and-down movements of the screw-supports the angle oi' connection between said supports constantly varies and the ear or bracket of the hinge part 9 is free to rollor slide in the fianged way 10 in the cradle.

It will be understood that while I regard the screws 8 as a desirable form of support they are illustrative only, as any other form oi support with means for operating the same may be employed without departing from the spirit of my invention.

Having thus described the invention, i
