T0 @ZZ whom, it may con/cern:

Be it known that I, JOHN P. LEIN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful` Improvements in Collapsible Berths, of which the following is a full, clear, and eXact speciication.

This invention relates to collapsible berths, and has reference more particularly to improvements in berths adapted for use on shipboard and in other places where the amount of space for operation and storage is limited. The objects of the invention are to provide a collapsible folding berth, one form of which can be turned up when temporarily not in use and which can be conveniently detached from its support for use as a stretcher when desired. Such a berth is particularly useful in a transport or warship, where a large number of berths are desired at intervals only and in connection withthe form thereof shown in the accompanying drawings, in which- Figure 1 is a perspective view of the preferred form of my invention. Fig. 2 is an end view showing the berth temporarily swung up out of use. Fig. 3 shows the berth swung up, the side frames being folded down. Fig. 4 is a detail view showing the supporting devices for the folding berth-frame. Fig. 5 is a detail view showing the manner of locking the supports. Fig. 6 shows the construction of the side frames. Fig. 7 shows a modification of the support, and Figs. 8 and 9 show a modified berth-frame construction.

` I have illustrated the invention as adapted for use on a ship where the berths when not in use can be cleared away entirely, leaving vthe space free for other uses. To this end I provide supports 1, which are' removably held at each end by sockets 2 and prevented from turning by pins 3, fitting in slots 4.

` As shown in the drawings, each pair supports two or more oppositely-disposed berths,

and a description of the mounting of one will suffice for the others. Rigidly secured to each support is a block or fitting 5, having sockets 6, to which a hanger 7, having T-headed lugs 8, is fitted, the T-head passing through the large part of the slot and then being pushed down and held against displacement by the narrow portion. (See Fig. 4.) Mounted on each hanger is a bracket comprising the cross-arms 9 and the braces 10, which may be riveted or otherwise secured. Pivoted on the cross-arm 9 is a link 11, and to the link ispivoted a chair 12, to which a rail 13 is fastened. The inner end of the rail is detachably secured to the support, preferably by a headed lug 14, which is inserted in a slot 15 in the support and held against displacement by a sliding latch 16, which is slid to ll up the slot after the lug 14 has been inserted. (See Fig. 5.) A similar construction is provided for the opposite support, and the berth-frame proper is detachably supported thereon in a manner I will nowdescribe.

The berth-frame comprises the side and end bars 17 18, secured 'at the corners by suitable corner-blocks, and the side frames are pivotally mounted thereon, so as to be foldeddown flat when the berth is to be stored. The.

rably joined at the lfour corners by pins 21,

which pass through holes 22 in a vsocket carried by one frame and a projecting end of the top bar. The pins are attached to the cornerblocks by chains to prevent loss. In folding the berth the side frames may be folded down on the springs 23 and then the end frames, the end frames being curved, as at 24, so as to overlie the side frames. It will thus be seen that the berth-frame can be folded up so as to be substantially iiat and will occupy a minimum amount of space.

Mounted on the end bars 18 are down- Wardly-eXtending legs 26, which have enlarged heads 27, adapted to engage the

rail

13, and 28 is a revolving latch on each rail, adapted to lock one of the legs 26 to hold the berth-frame rigidly in place. By opening the latches 28 the berth-frame can be disengaged from the rails 13 and used as a stretcher and can be securely held by the latches when not so used. This provision is of especial advantage where the berth is used in a sick-bay of a ship, as it permits the patients to be easily transferred as desired. The four legs also prevent any longitudinal oscillation of the IOO IOS

frame because of their engagement with the rails, thus forming a rigid structure.

In order to turn the berth up when not in use, the rails 13 are disengaged from the supports and the front of the berth-frame swung upward on the links 11 to the position shown in Fig. 2, an adjustable notched bracket 29 or other suitable catch being provided to engage the rear side frame to hold the berth in vertical position against the supports orV wall. As shown in Fig. 2, the berth-frame is turned up without collapsing the side frames; but in Fig. 3 I show the parts turned up with the side frames collapsed, thus requiring much less space. The bracket or catch 29 is made adjustable on the supports or support for this purpose. It will be observed that the head-room between the berths is not obstructed at the ends by the berth-frame supbracket-support 30, which are attached to the supports by hooks 31, passing through a slot in the vertical bar of the bracket. In this form the berth is not adapted to be turned up vertically, but can be folded for storage, as before described, and can also be separated from the rails for use as a stretcher in the same manner as before described.

Figs. 8 and 9 show a modiiied form of collapsible stretcher-berth, in which the berth is supported at each corner, the upright supports being provided with one or more headed pins 32, which are engaged by hooks 33, cast on the corner-blocks 34 of the end frames. The corner-block 34 has a proj ecting pin 35, which iits into the end 36 of the upper side rods 37, and when the berth is hung on the pins 32 at each corner the side frames are rigidly held in upright position.

AThe pins 21 may be provided where desirable for fastening the corners, as before described;

but this form is readily removable from the supports by disengaging from the pins and can then be collapsed, as before described. The other three corners are similarly constructed, and the upright support (shown in Fig. 9) has four pins, because it is adapted to support the adjacent corners of four berths.

Having thus described my invention, I declare that what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with supports, of hangers or brackets adapted to engage said supports, rails carried by each bracket, a berthi frame adapted to engage said rails at each end, and means for locking said berth-frame to said rails, substantially as described.

2. The combination with supports, of hangers or brackets adapted to engage said supports, a berth-frame having means for engaging said brackets and thereby rigidly connecting the supports, brackets and berthframe, and means for locking the berthframe to the brackets, substantially as described.
