CARRIAGE OR MOUNTING FOR ART'l LLERY.

SPECIFICATION forming part of Letters Patent No. 531,417, dated December 25, 1 894.

Application filed November 15, 1898. Serial No- 490,982- (No model.)

To all whom it may concern:

Be it known that I, HERMAN J axonsson, engineer, a subject of the King of Sweden and Norway, and a resident of London, England, have invented certain new and useful Improvements in Carriages or Mountings for Artillery, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to wheeled carriages or mountings for artillery and is designed to increase the stability and durability of such mountings and to facilitate the elevation and training of the guns thereon.

The gun is carried by and moves with a cradle which is mounted on a transom secured to the trail, .and so as to be capable of horizontal and vertical movement independently of said transom.

A'special feature of importance and novelty consists in securing the transom to the trail in the plane of the axle and mounting the cradle on such transom so that the gun will be raised but very little above the axis of the wheels. In any case, however, the advantage of fine and accurate adjustment for elevation and laying is secured by the employment of the cradle.

Referring to the accompanying drawings, Figure 1 is a side elevation of a portion of a gun mounted in accordance with this invention, the mounting being shown in section. Fig. 2 is a vertical transverse section of the gun and cradle taken through the center of the supporting transom. Fig. 3 is a plan of a part of the mounting hereinafter described. Fig. 4 is another view similar to Fig. 1, but showing a still further modified form of the mounting. Fig. 5 is a plan of the same.

Like letters of reference denote corresponding parts throughout the drawings.

A is the gun.

B is the cradle.

Q is the axle.

D, D are the wheels.

E is the trail.

For controlling the vertical turning movement of the gun and axle and for training or turning the gun horizontally for fine or ac-,

curate laying, without moving the trail of the carriage, provision is made as follows: that is to say- F is a suitable frame or arm attached to the transom J and entering at its rear end a guide G which is secured to the gun cradle. The said guide G can move laterally on the frame F as hereinafter described when the gun is trained for fine or accurate laying. The elevating gear comprises a screw-threaded shaft H through a nut H supported by a tubular piece H trunnioned in the trail sides. The said nut H can be rotated by a hand wheel H at the side of the trail acting through bevel gear wheels H The rear edge of the frame F is provided with a toothed segment F. With the said segment there engages a worm I, the shaft of which is carried in bearings formed on or attached to the cradle. I is a hand wheel for turning said worm. The worm is not capable of endwise movement relatively to the cradle and hence when it is rotated and thereby caused to travel along the toothed segment, the cradle is carried with it thus-effecting the fine lateral pointing or laying of the gun without moving the trail. The guide G is made sufiiciently long to allow of the desired amount of lateral turning movement.

It will be observed that the shock on the elevating gear due to the jump of the gun when firing is not transmitted through the horizontal training gear,and hence the latter som and are held in place by a block F that fits between the jaws on the under side of the transom and is secured by bolts F F is a table preferably formed whole or in one piece with the frame or arm F and adapted to re-. ceive the cradle which is furnished with pieces B hook-shaped in transverse section that engage with the edges of the table and prevent the cradle from rising. The forward and rear ends F, F, of the table are curved to form arcs of circles having a common center, and

ICC

the two sides F F of The table are flat, as in the plane of the axle, of a cradle mounted clearly shown in Fig. 3. The opposite curved on said transom and movable vertically for portions of the table together form a pivot elevation and horizontally for accurate layabont which the cradle can turn for horizoning independently of said transom, and'a gun tal laying. The flat sides enable the cradle ,mounted in the cradle, as set forth.

to be placed on and taken ofi the table. The 2.
