IMPROVEMENT IN INVALID-BEDSTEADS.

Specification forming part of Letters Patent No. 169,067, dated October 19, 1875 application filed l l July 17, 1875,

' To all whom it may concern:

our invalid-bedstead, and Fig. 3 is a planv view of the same.

This invention has relation to improvements in invalid-bedsteads, whereof the portion of the bottom nearest the head-board is capable of being adjusted at an angle to the remainder, for the purpose of vholding the invalid in a reclining position; and the nature of the invention consists in combining with the frame of the bedstead and its verticallyvibrating section two or more gravitating and notched supports, pivoted to the handles, whereby the movable section is raised,

which supports automatically engage with a transverse brace of the bed frame as the said section is raised, thereby' dispensing with all extraneous aid for the purpose, as will be hereinafter more fully explained and claimed.

In the illustration of my improved device I propose to show its application to an iron bedstead of the description commonly used in hospitals;`but it will be evident that it may be used in connection with any descrip- Ation of bedstead with equally good results.

In the annexed drawings, A A designate, respectively, the head and foot boards of an invalid-bedstead, whereof F F are the side rails, which latter are composed oftwo sections, b b', hinged together at a. Section b is rigidly secured at its rear end to foot-board A', its front end being rigidly secured to a supplementary supporting-rail, D, the front end of which is bolted or otherwise firmly attached to the headboard A. Section b' and rail D are connected by brace-rods c c with the head and foot boards, thereby holding them against all' displacement relative to each other, and giving them the necessary rigidity. Section b, which is thus endowedl with an independent vibratory movement, is

'provided with operating-handles B, which project through the head-board for the purpose of allowing an attendant to raise the same while standing at the head of the bed, to which handles are pivoted vertically-vibrating and gravitating metallic supportingstandards C C. These standards are each of the head-board, and the moment the desired adjustment has been obtained will bite upon the said rod, thereby holding the said section in an inclined position.

When it becomes necessary to lower the inclined section the attendant will seize both the handles of the supports and those of the said section, and raising the latter slightly will compress the said handles, when the supporting-rods C C will become disengaged fromJ rod o, and the adjustable section lowered to any desired extent. A

The space between the side rails F F and the head and foot boards is filled in by means of at interlaced strips of metal H E, the adjacent ends of the former being hinged together by means of loops a', while their outer ends, as well as those ol' vstrips E, are attached to loops d, forming a component partof wire springs G', formed by coiling a wire around cylindrical rods I I', arranged at each end'and at the sides of the bed, las shown in Fig. 3.

By this means my improved bedstead is provided with a spring bottom, which is adapted,`by means of hinges a', to bend with and4 ,eonforn to the movements of adjustable section b of the" bed. 4

What we claim as new, and desire to secure by Letters Patent, is-

`'lhe combination, with the handles B, of adjustable section b, of the vertically-vibrating and gravitating supports C, having handles l, substantially as specified.
