SPECIFICATION forming part of Letters Patent No. 297,256, dated April 22, 188.4.

Application filed February 9, 1884. (No model.)

To all whom, it may concern:

Be it known that I, .HENRY S. HALE, acitizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful. Improvements in Folding Berths, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a transverse vertical section of a sleeping-car containing my invention,the central portion being broken away. Figs. 2 and 3 are details enlarged. Fig. tais a partial vertical transverse section, showing a modification. Figs. 5, 6, and 7 are partial vertical sections, showing other modifications. Fig. 8 is a parf tial longitudinal vertical section.

The object of my invention is to construct a sleeping-car berth and its supports in such manner as to facilitate the folding up and letting down of the saine by means of such a construction and arrangement of parts as shall make the front and rear edges of the berth counterbalance each other upon its pivotal Supports.

To this end one part of the invention consists, essentially, in connecting the rear or inner edge of the berth with its pivotal supports by means of a chain running overa pulley above the berth, one end of the chain being attached to the said inner edge of the berth, its opposite end being attachedto the pivotal supports.

Referring particularly to .the left-hand portion of Fig. l, A is the outer Wall of the car; B, its inner wall, arranged at some distance from the outer wall, and C the roof or deck of the car.

D is the end rail of the berth, there being, of course, a similar endrail at its opposite end,with suitable longitudinal rails and a bottom, which may be of substantially the character commonly employed in sleeping car berths.

At the inner end of each rail D there is a heelextension, E E', preferably of metal,which projecting through avertical slot, b, in the inner wall of the car and carrying an anti-friction wheel at awhich is mounted upon a stud projecting laterally from the heel-extension,

engages with the vertical walls of a slot or strips, however, areobjectionable. `When pref ferred, however, the inner ends of these rails and the outer edge of the berth may be rounded, as indicated in dotted lines ci of the righthand portion of Fig. l, and a bead or molding, d, may b e added for the purpose of ornamentation.

Fis the permanent portion of thehead-board or partition between the ends of the berths.

.G G is ajointed link, pivoted at its upper end to the partition F and at its lower end to the end rail, D. t

H H is a chain connected at one end to the jointed link at about its center, and at its other end to the end rail, D, the doubled portion of the chain passing over apulley, a, and thence round a pulley or sheave, ci, attached to the heel-extension E E.

By an examination of the left-hand portion of Fig. l it will be readily understood that as the berth isv folded up from the horizontal position shown in full lines to the inclined position shown in dotted lines its inner side or edge moves downward andis supported by the doubled end of the chain; and it will be found in practice that very little power is required to move the berth up and down, by reason of this counterbalancing arrangement of chains and links. It will of course be understood that the berth,when let down, is supported both by the jointed link G G, and also by the chain H H.

I is a locking-bar arranged between the inner and outer walls of a car. Itis connected IOO berth iirmly in position. So, also, when the berth is let down for occupancy, the latch enters another Uslot, il, in the bar I and holds the berth firmly in its horizontal position. As indicated in Fig. l, thislatch-bar is connected directly to the heel-extension of the end rail, so that the spring-latch can be arranged within that portion of the seat which is occupied by the cushions, when the cushions arein theposition indicated in Fig. 8; and, when desirable, the inner ends of the vertical cushions may be cut away to receive the projecting end ofthe latch. By preference I employ two ofthese Vertical bars, one at each end of the berth.

As indicated in Fig. 8, one vertical bar is employed at about the center of the berth, its upper end being connected to a longitudinal rod, I', which is supported at its ends in the heel-extensions, the vertical bar running down between the windows ofthe car, in which case the locking-latch is arranged between the two adjacent seats, and preferably near the lower line ofthe windows.

In the right-hand portion of Fig. l I have shown a chain, J, instead of the jointed link G G, and in this instance a chain, K K, is connected at its ends to the chain J, running thence over pulleys c a', the lower doubled end ofthe chain passing round a pulley, e, on the inner end of the heel-extension.

L, in same ligure, is a chain connected at its upper end to either the chain K or to the inner end of the heel-extension, thence down round a pulley, a2; thence horizontally to the end of a draw rod or link M, which is arranged between the backs of two adjacent seats.

m is a knob on the upper end of drawrod M,which the operator can take hold of to pull upon the chain L, in order to assist in turning up the berth.

M (see Fig. 3) is a locking-plate provided with a central slot, m', through which a pin, m2. attached to the draw-rod, and at right angles thereto, can pass, when turned in the proper position, the relation of these parts being such that after the operator has pulled the pin fm? through the slot m', just at the time the berth reaches the limit of its upward movement, he can then twist the draw rod so as to turn the pin crosswise of the slot m', and thus lock the berth securely in its uppermost position. u

ln Fig. 4 the heel extension E carries at e' an anti-friction roller, which traverses a Vertical slot, f, in the vertical partition F, and a chain, H', is connected at one end to the jointed link G G', passes thence over apulley, g, supported on the permanent headboard or partition, thence down to the heel-extension, to which it is attached, the chain thus serving to support the inner edge of the berth, and assist in counterbalancing it. lVhen preferred,

however, the heel-extension may be continued through the slot b, and have a weight, D2, attached to the inner end, E, of the heel-exten sion. Vhen this extension and weight are used, an anti-friction roller at c* may be attion, in which thejointed supporting-link is f made in three parts, Gr G G2, and in this instance two chains, HI H2, may be each attached at one end to the jointed link, and at the opposite end to a third chain, H3, the lower end of which is connected to the heel-extension for the purpose of corunterbalancingthe berth; but I do not wish to be limited to the employment of the two chains II" H2, because one of them might be omitted, in which latter case I would prefer to attach the single chain to the part Gr2 of the link at about its center-that is to say, about midway between the pivoted ends of said part G2.

In Fig. 6 I have shown another modification, in which the parts are substantially the same as those above described, and shown in Fig. 4, except that I propose to employ a weight, D, connected by chain H3 to thejointed link; and in this instance I propose to use a locking-bar, l, to be attached at its upper end to the inner end of the heel-extension, and provided at its lower part with slots to receive a locking-latch, substantially as has been referred to.

In Fig. 7 I have shown another modification, in which the upper part, N N, of thejointed link is pivoted labout midway its length-say at a-to the partition F, the lower part, O, of the link being pivoted to the upper link and to the end rail, D. The upper part, N, of the link traverses a slot, b', in the inner wall of 'the car, and P is a chain attached to that end of the pivoted link and extending downward, where it passes round a pulley to 'a draw-rod. substantially like the draw-rod M, which has been described. Ofcourse,the draw-rod may be provided with locking devices for the purpose loo IIO

of holding the berth in its position when swung upward.

In the working of myinvention, the pull in an upward direction of the pivot which con nects the lower end of thejointed link to the berth is effected by pulling` the central part of said link toward the vertical plane of the inner edge of the berththat is to say, toward the side of the car; hence it will be understood that with a uniform weight or pull upon the inner end of the counterbalancing-chain the actual lift upon the pivot at the lower end of the link is greatest when the berth commences to move from its horizontal positionY and points of attachment and support of the chains without departing from the spirit of my invention; but Ihave shown such as I believe to be best now known to me for the working of my invention, and such as will under ordinary circumstances secure satisfactory results. Neither do I wish to be limited to the employment of my invention in connection with a sleeping-car, because it is equally well adapted for the hanging and support of berths in steamboats, bed-rooms, and other places where folding berths may be found desirable. Nor do I wish to be limited to the use of my invention in connection with a berth in which its inner edge rises and falls, because under many circumstances it will be found advisable to use the chain and weight or chain and drawrod in connection with berths which are hinged at their inner edges directly to a vertical Wall, for the purpose of assisting in counterbalancing.

On another modification I propose to employ the jointed link G G and cord connecting the link with the inner edge of the berth, and running over a pulley at a', in combination with a supplemental lifting-cord attached at one end to the berth near its front end, and at its other end to a fusee and spring, substantially as is commonly done in sleeping-cars; or the cord may run over a pulley or pulleys (see Fig. 4) or two pulleys, a a", (see Fig. 7,) and have ya weight, D2, attached.

I also propose to construct the inner end of each link with a projecting shoulder or stop, v g2, under such an arrangement of parts that these stops shall each engage with the edge of the opposing member of the jointed link and prevent them from being straightened out, (see Figs. l and 9,) so that this construction relieves the chain from further pull outward after the berth reaches a horizontal position.

I also propose to use stops or shoulders f 2- one at each end of the berth-against which the inner end of the rails strike and abut when the berth is let down. i

In all ofthe constructions shown an upward pull or lift upon the berth is exerted through the medium of the jointed link, and in each and every construction this lifting is effected by movingV the central or substantially central portion ofthe link away from a line which intersects the pivots by means of which the jointed link is connected to the end ofthe berth and to the partitions between the ends of the berths.,
