BED.

SPECIFICATION formingpart of Letters Patent No. 598,473, dated February 1, 18981.

Application filed August 9 1 8 9 7.

" ported cradles and beds; and the objects are,

first, to impart a maximum movement to the foot of the bed, which decreases' gradually in .amplitude from the foot to the head, where the minimum movement will be practically nothing, thereby conducing to the health and comfort of the occupant, and, second, to provide means for rendering the bed practical for people of different weight. Y

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure l isa view in perspective of a childs bed equipped with my improvements; and Fig. 2 is a view in longitudinal vertical sec tion of the bed as shown in Fig. l, except that theadjustable leg is down in position to counteract the swinging movement of the bed.

Similar letters of reference indicate like parts throughout both views of the drawings.

In the annexed drawings, A represents the body of the bed, which is suspended from a frame B. The front posts of this frame are connected by the transverse rod b, and outside hooks 'a on the head of the bed `sustain that end by engagement with the rod in the manner as shown in the drawings. The frame-posts at the foot of the bed are proj ected up above the bed-body, and from them the bed-body is suspended by means of the springs O O, which will preferably be spirallywound wire springs, but may be of any Vsuitable elastic material, as rubber or the like. Outside hooks b on the foot of the bed-body provide means for detachably fastening the springs O O to said body, and the latter will be suspended by said springs.

The bed-body will vibrate about the rod b, and the tension of the springs should be suficient to maintain the foot of the bed approximately on a level with the head when the occupant is lying quietly in the bed. A

Serial No. 647,524. (No model.)

plurality of hooks d, arranged in vertical series, will be provided, whereby when the weight is so great that the bed inclines constantly toward the foot the head can be lowered by changing the rod into one of the up-` per hooks. The drawings illustrate a childs bed, and the rod is in the lowest hook; but as the child growsV in size the hooks above will be brought successively-into use, and when the springs are finally inadequate to support the child the vibrating feature of the bed may be dispensed with by swinging the legs D down into contact with the longitudinal bars connecting the head and foot posts of the frame together, whereby both ends of the bed-body will be immovably supported.

The legs D are short wooden or metal bars, which are pivotally secured to the bed-rail and are long enough to reach the top of the longitudinal bars .connecting the head and foot posts of the frame and support the foot end of the bed on a level with the head. The

legs are pivotally secured, whereby they may will be secured by increasing the number of springs, by which the foot of the bed-body will be suspended from the supporting-frame.

As the swinging movement of the bed has a tendency to cause the bed to slide forward over the floor, I prefer to use rollers only nnder the two front posts of the frame. The

posts at the foot being without rollers, will increase the friction and prevent the crawling forward of the bed.

By pivoting the bed-body at the head and -elastically suspending the foot the motion will be imparted almost wholly to the middle and lower extremities of the body, and the head will remain comparatively quiet.

IOO

Having thus fully described my invention, what I claim as new, and Wish to secure by Letters Patent of the United States, is

1. In a bed, the combination, with a port-V able frame having a transverse rod, of a bedbody having a double series of vertically-arranged hooks to engage said transverse rod on the frame said hooks being at the head end of the bed, and springs connected at one of their ends with the frame and at their other ends with the bed-body, al1 substantially as described and for the purposes specified.

2. The combination, with a frame, of a bedbody pivotally secured at its head end to the n frame and elastically suspended therefrom at its foot end and having legs pivoted to said bed-body close to the foot of the bed and adapted to be turned down against the frame, substantially as described and for the purposes specified.

I In Witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 19th day of July, A. D. 1897.
