To all whom it may concern."

Be it known that I, J AMEs ALLAN, a citizen of the United States, residing-at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Spring-Beds, of which the following is a specification. o Y' The object of my invention is to produce a spring-bed adapted to be folded together, so as to occupy less space when required for transportation, and having a simple means of adjustment whereby itmay be easily increased or diminished in'width, so as to be readily adapted for bedsteads of different sizes, all of which will be fully and clearly hereinafter shown, described, and claimed, reference being had to the accompanying drawings, in which- Figure lis a plan or top view of the bed complete, two of the spiral springs being left off so as to show the adjusting device below them. Fig. 2 is an end View, some of the spiral springs beingleft oft' so as to show the upper and lower devices for adjusting the Width' of the bed. Fig. 3 is an end view'of the bed folded together. Fig. 4 is a front view of the upper adjusting device, and Fig. 5 is an end view of a portion of the same.

The upper frame consists of the side pieces ofband-iron 1 and 2 and the end pieces, 3 4 and 5 6, the whole being securedat the, corners by rivets 7, in the usual way. The free ends 8 and 9 of the bars 3 4 and 5 6 are passed through a yoke, 10, and are adapted to slide back over each other, and thereby adjust the width of the bed more or less.

When adj usted'to the point desired, the piece 11 is inserted edgewise or endwise, into the opening in the bottom of the yoke, and then turned around by the thumb-piece 12, as shown in Fig. 4.

The piece 11, as will be seen, is provided with a rounded or inclined bottom portion, 13, so that when it is put in place within the yoke and turned partly around the inclined portion 13 wedges against thelower inside parts of the yoke and rigidly clamps the two portions of the bars and keeps them rmly in place wherever adjusted. 1f desired, an ordinary thumb-screw may be used in place of the fastening device described.

The lower frame is made in two sections, A

and B, and each consists of the

side framepieces

14 and 15, the

end pieces

16 and 17, and the

longitudinal bars

18 and 19, all being firmly secured together in the usual way by rivets. These upper and lower frames are secured to each other bythe spiral springs 20, by rivets 21 to the bottom frames, (see Fig. 1,) and to the top frame by the usual loops, 22, riveted to the frame in any well-known Way. The remaining portionsofthelowerframearecovered by similar springs, 20, riveted in the same way thereto, lthe tops-of the springs being connected with each other by the usual chains', 23, and at the top of each of the springs located on the bars 15 is a small hook, 24, adapted to take up the slack in the chains 25, just above the sections A and B, when they are adjusted so as to decrease the extreme width of the bed. This can be done, as will .be seen, by hooking into any ofthe links of the chains 25, so that any amount of slack required may be taken up.

The lower framesections, A B, are adjusted to or from each other by the` pivoted bars 26. (See Figs. 1 and 2.) There are two of these bars 26, and each are provided with one or more notches, 27, adapted to catch over a folded together as shown in Fig. 3, which operl ation brings the two lower frame-sections on the outsides, and the tops of the spiral springs together, as shown.

I am aware that prior to my invention bedbottoms have been made to fold together, and have also been constructed so that the width could be adjusted more or less. -I therefore with the lower ends of the springs and pro- ICO vided with the pivoted bars 26, having a sepivoted bars 26, provided with a series of ries of notches or side openings, 27, adapted notches or side openings, 27, and the rivets 28,

to catch over the rivets 28, substantially as whereby the width of both the bottom and the and for the purposes described. top of the bed may be adjusted and firmly se- 15 5 2. A spring bed-bottom consisting of the cured in said adjustment, or the sections A upper side frame-pieces, l and 2, end pieces, and B may be separated suiciently to allow 3 and 4, 5 and 6, and the springs 20, secured the bed to be folded, substantially as described.
