GUN-CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 455,166, dated June 30, 1891.

Application filed July 1l, 1888. Serial No. 279,693. (No model.) Patented in France March 16, 1886, No. 174,807, and in England ,Iuly 9, 1887,1I0. 9.687.

To all whom it may con/cern:

Be it known that I, JEAN BAPTISTE GUS- TAVE ADOLPHE CANET, engineer, a citizen of the Republic of France, and a resident of Paris,France, have invented new and useful Improvements in and Relating to Gun Carriages or Mountings, (for which I have obtained patents in the following countries: Great Britain, No. 9,687, dated July 9, 1887, and France, No.174,807, dated March 1o, 1886,) of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to gun carriages or `mountings chieiiy designed for use on ships or behind walls or parapets with or without embrasures or ports.

The said invention comprises means for housing the gun and its mounting entirely behind or inside of the armor, wall, or parapet, so that the gun port or opening can be closed, and for readily running out or returning the gun and mounting to the iii-ing position.

The said invention also comprises other improvements hereinafter set forth.

In the accompanying drawings, Figure 1 is a side elevation, partly in vertical centralsection, of a carriage or mounting constructed according to the present invention and designed for a gun having a very long'chase, the gun being shown in the firing position. Fig. 2 is a plan,partlyin horizontal section, on the line a.' 0c and on the line ,Fig. 1. Fig. 3 is a rear elevation, partly in transverse section, on the line 22,Fig. 1. Fig. is a transverse section of part of the gun-mounting on the line y y, Fig. 1. Figs. 5 and G are views, hereinafter referred to, showing details of construction. Fig. 7 is a longitudinal central section of a portion of a gun-mounting, showing a modification of my invention hereinafter described.

Like letters indicate corresponding parts throughout the drawings.

A is a strong base-plate, which has formed thereon or firmly attached thereto a circular or segmental rail, racer, or roller-path A', and which is rigidly secured to the deck of a ship or to any other suitable platform. Another rail, racer, or roller-path B is also rigidly secured to the deck or other platform.

C is the chassis, frame, or under carriage, which rests by means of two rollers or trucks D and two pairs of rollers or trucks E upon the said circular or segmental rails, racers, or

roller-paths A B. v Ciiis the cradle or top carriage, in which the gun is supported by its trunnions.

The chassis or frame C is connected by a strong bolt F to a pivot-link G, which has vformed thereon the eye G for the pivot-pin or pint-le Il, and also a clip G2, which engages with a projection or ilange A2 on the baseplate A and prevents tilting of the said chassis or frame.

The training or traversing of the gun is effected by turning the frame or under carriage upon or about the pivot-pin or pintle H by the means hereinafter mentioned or by any other suitable means.

The mechanism for effecting the housing of the gun and mounting so as to bring the .gun entirely to the rear or inside of the wall or parapet comprises a strong screw-shaft J, working in two nuts K L. The nut K is firmly secured in a boss or bracket G3, formed lwith or firmly attached to the pivot-link G,

and the nut L is firmly secured in the frame or under carriage C. The screw-shaft .I has a right and a left hand screw-thread, the nut-s K L being correspondingly screw-threaded. Upon the screw-shaft .I is mounted'a wormwheel M, provided with akey, which is fitted to slide in a longitudinal groove or ke'yway formed in the said screw-shaft and extending to the rear end thereof. This worm-wheel is geared with a worm or endless screw N, the shaft N of which is to be provided at its eX- tremities with suitable driving cranks or handles. y

To facilitate the backward movement of the frame or under carriage C, it is provided in front with a pair of rollers or trucks O, which rest upon straight rails or ways P, secured to the deck or firing-platform. The traversing rollers or trucks E at the rear of the mounting are carried by pivoted blocks Q, so that by turning the said blocks through an angle of about ninety degrees the rollers or trucks E can be adapted to run upon the said rails or ways P. One of the blocks Q is shown more clearly in section in Fig. 4t, in side elevation in Fig. 5, and in rear elevation in Fig. 6. Each block Q is provided with a pivotpin Q', which extends upward th rough a bearing C on the frame or under carriage C, and which has fixed upon it a collar Q2, having a projecting arm Q3, Fig. 3, whereby the said [of block may be turned for the purpose above f specified. Each block. Q is, moreover, provided With a hook, catch, or clip R, pivoted or clip R at either extremity of its movement,

two holes Q4 Q5 are formed in the block Q and a pin R2 is passed through a hole in the hook or catch R and into one or the other of the holes Q4 Other suitable means may, if desired, be employed for holding the said catches or clips at either extremity of their movement.

The ruiming in or housing of' the gun and mounting is effected as follows, viz: Assuming the gun to be in the firing position on the mounting, the frame or under carriage is so adj usted upon the rails A B and the blocks Q, carrying the rollers or trucks E, are so turned that the said rollers or trucks may run upon the straight rails or ways P, the hooks R being turned down so that they engage With the flanges P of the said rails or Ways P. The gun and the top carriage C* are then run back by any convenient means to their rearmost position upon the chassis or under carriage C, as indicated by dotted lines in Fig. l, and are held in this position by means of locking-bolts or other suitable devices. The bolt F, which connects the frame or under carriage C with the pivot-link G, is withdrawn, and the cranks or handles, which actuate the screw-shaftJ through the medium of the worm N and Worin-wheel M, are turned in the proper direction to move the frame or under carriage backward along the straight rails P upon the rollers or trucks O E.

The screw-shaft J is made of such length that when it has moved the frame or under carriage to the rear extremity of its course, as indicated by dotted lines in Fig. l, the gun is brought completely within the armor or behind the wall or parapet. It can be maintained in this position, if necessary, by means of' tension-screws or other securing-gear and the gun-port can be closed.

The return of' the gun and carriage or mounting to the firing position is effected by reversing the above-described operations.

For training or traversing the gun and mounting atoothed segmentdis formed on or attached to the base-plate A, and has geared with it a pinion b, fixed on a vertical shatth, on which is also fixed a worm-wheel c. This worm-wheel is geared with aworm d, fixed on a shaft d', arranged to be driven by chaingearing actuated by means of the hand-wheel e; or the training of the gun may be effected by means of other suitable gearing.

Instead of making the screw-shaft .I with right and left hand screw-threads and employingtwo screw-nuts thereon, as above descrlbed, I sometimes make the said screw-shaft with a right-hand thread or with a left-hand thread, arranged to work in the nut K or in the nut L, and I provide the said shaft with one or more collars, which work in a corresponding block or bearing used in place of the nut Lor K, as the case may be, thus forminga thrustbearing. In Fig. 7 I have shown an arrangement of this kind wherein the nut K is replaced by a thrust-bearing. The screw-shaft J when rotated turns in the thrust-bearing K and nut L, and, without itself moving endwise, imparts the desired longitudinal movement to the gun-carriage. When a thrustbearing is substituted for the nut L instead of' for the nut K, the screw-shaft .I when rotated moves endwise, and thus imparts the desired movement to the gun-carriage. The right and left hand screw-threads have, however, the advantage, in the case of long guns, of increasing the speed with which the housing of the gun and mounting and the return thereof to the firing position can be accomplished and of reducing the length of that part of the screw which projects at the rear of the frame or under carriage when the latter is in the firing position.

What I claim isl. In a gun-mounting, the combination,w1th

the under carriage, chassis, or frame, of a` pivot-link secured at its forward end to a deck or platform, a pin or bolt for connecting the said under carriage, chassis, or frame with the said pivot-link, a screw-shaft carried by the said under carriage, chassis, or frame and by the said pivot-link and working in a nut in one of these parts, and means, substantially such as above described, for rotating the said screw-shaft, for the purposes above specified.
