SELF-LEl/ELING SHIPS BERTH.

SPECIFICATION forming part of Letters Patent No. 567,708 dated September 15, 1896.

Application filed October 31, 1895.

To all who/wit may concern: Be it known that I, JAMES COODWIN, a subject of the Queen of Great Britain, residing at Lynn, in the county of Essex and State 5 of Massachusetts, have invented certain new and useful Improvements in Self-Leveling Ships Berths, of which the following, taken in' connection with the accompanying draw ings is a specification.

My invention relates to certain improvements in self-leveling berths, of which the following is a description sufficiently full, clear, and exact, to enable any person skilled in the art or science to which said invention appertains to make and use the same.

Referring to the accompanying drawings, Figure 1 is a side elevation of my improved self-leveling ships berth, the side of the berth being broken away; Fig. 2, a top plan view, partly in section, taken on line a- .in Fig. 1; and Fig. 3, an end elevation of the berth.

Like letters and figures of reference indicate corresponding parts in the different figures of the drawings.

My invention relates especially to mechan ism for supporting a ships berth so that it will maintain a level position, compensating for the roll or pitch of the vessel, the object being to producea cheap, simple, and effective device of this character.

The nature and operation of the improve ment will be readily understood by all conversant with such matters from the following explanation In the drawings, A represents the side of the ship, B the standard from which the berth is suspended or the cabin partition, and C the ceiling.

Centrally at the top of the standards adj acent the ceiling there are small partitions b, in which laterally-curved arms (1 are swiveled at f. i

The berth D may be of any suitable form, its head-board h and foot-board z' being disposed within a very short distance of the standards B or partition-wall. Pivoted to swing vertically from each corner of the berth there is an. arm j in. These arms are respectively pivoted to rotate in the lower ends of the adjacent curved arms 01. In the bottom of the berth at each end there is a hook m,

Serial in. 567,471. (No modem 0 and an eye 1) is secured to the cabin-floor E. A cylinder (1, containing the coiled spring (indicated by dotted lines) is detachably secured to the eye 19, and a plunger r, therein tensioned by said spring, has an eye If for attaching it to the hook 771- on the berth. On each standard adjacent the head and foot of the berth there is a metallic plate 1*, in which are formed two sockets 1r. (Shown at the right in Fig. 2.)

\Vithin the bottom of the berth two sliding blocks 3 are arranged. These blocks carry pins awhich project throughthe headandfoot, respectively, of the berth, and are adapted to enter the openings 11; in the plate 0 and lock the berth against movement. These blocks are pushed by springs 15, interposed between them and a brace-bar 10 within the berth. One side 17 of the berth. is slotted, at 18, 1011- gitudinally, (see Fig. 2,) and a curved handlever 19, pivoted at 20 ina support, works in said slot. Runnin transversely of the berth a shaft 21 is pivoted, bearing a pinion 22 at the end. The lower end of the lever 19 is toothed to engage said pinion.

On the shaft 21 there is a gear 25. tackbars 26 and 27, horizontally arranged and respectively connected with sliding blocks y at the head and foot of: the berth, mesh with said gear.

The mattress P .is supported by any suit able frame 30 above this mechanism.

As shown, the hand-lever is in the position assumed when the pins 2 are housed. A 8 5 shoulder 31, formed in the slot, holds the lever against the tension of the springs 15, said lever being thrown behind said shoulder by springs hen the lever is moved in the slot in the position shown in dotted lines the springs 15 project the sliding blocks and throw the pins .2 into the sockets w in the wall.

When the berth is in use thepins are housed therein, as described.

The rocking of the vessel sidewise is con1- 5 pensated for by the supporting-arms (Z 70, swiveled and pivotally connected, as described. By moving the arms, as shown, in side elevation and throwing the center 50 forward toward the center of the berth the pitch is also compensated for. Moreover, the spring connections q serve to relieve the motion in a manner Which Will be understood Without a more explicit description.

The locking device is employed when th device is not required for use.

A ball-and-socket joint may be used for swiveling the arms d, or any other suitable means employed to impart a universal movement thereto.

Having thus described my invention, What I claim is- 1. The combination With the standards of the berth; the curved arms at each end swiveled in bearings attached to said standards; and the curved arms pivoted to swing vertically on said berth and pivoted to rotate in the lower ends of said swiveling arms.

2. The combination With the berth and standards of the curved supporting-arms d, swiveled to said standards; the curved arms to the arms (I, substantially as described.

" sagas 3. The berth, and its supports, in combina tion With the spring-pushed pins z therein; the hand-lever pivoted onsaid berth, and gears connecting said hand-lever and pins 21 whereby the pins may be housed.

4E. The combination With the berth and its supports provided with sockets to, of the spring-pushed blocks y, arranged Within the bottom of the berth and carrying pins 2'; the 3 racks connected with said blocks; a gear meshing with said racks; a hand-lever and connected mechanism for actuating said gear.

In testimony whereof I have signed my name to this specification, in the presence of 31 two subscribing Witnesses, on this 28th day of October, A. D. 1895.

JAMES GOODXVIN.
