7 arbor/"c41 .frame adjusted to bow JOSEPH BARTHOLOME, 0F BALTIMORE, MARYLAND.


Specification of Letters Patent. Patented Feb. 21, 1911.

Application filed October 15, 1909. Serial No. 522,705.

To all whom ti -may concern;

-Be it known that I, JOSEPH A. BARTHOL- OME, a citizen of the United States, residing at Baltimore, in the-State of Maryland, have invented certain new and useful Improve-' ments in Invalid-Bed Frames, of which the following is a. specification.

This invention relates to a metal bedframe having an improved construction that adapts it especially forhospital use and for certain surgical operations.

The invention is illustrated in the accompanying drawing, in which a Figure 1 is a side View of the metal bedthe legsof a patient with relation to his body so that said parts will have a position approximating that which they have when the person is seated in a chair. Fig. 2 shows the adjustable parts of the metal bed-frame all in a flat or horizontal position. Fig. 3- is a perspective View of the metal bed-frame but without the wire netting, and shows the parts adjusted as they are in Fig. 1. Fig. 4 shows the preferredconstruction of' handle, or grasp loop onthe adjustable leg-part.

The base comprises a rectangular frame made of angle-iron, one side, 1,'o:t which iron has horizontal. side, 2. vertical tangular frame has a diagonal'brace-bar, 29, which is riveted to the horizontal flange, 1, of the angle-iron;-these diagonal bars give rigidity to the frame.

All the parts of this apparatus are made of metal. The back-frame, A, comprises two parallel side arms, 3, an end cross-bar, 4, united to the side-arms by corner bends, 5, and a -piv,oting cross-bar, 6, to which'the of said iron projects-upward in a ends of the two side-arms are attached, and

said pivoting cross-bar having journal ends, 7, of reduced size which fit in holes in the upward-projecting sides, 2, of the angle-iron frame=-- Each side-arm, 3, of the back-frame is provided witha stiff-rod loop, 8, extendingin alinement with the side-arm, but projecting in a plane above the ,same. These rod-loops, 8, serve as side ra'ilsto retain the mattress (not shown) serve as a hand-grasp to assist in adjusting. the said pivoted bac r-frame, A. VVoven wire or crossed wires, 9, are attached to and stretched across the fonrsides of the back supports the mattress' frame and this wire The back-frame has a brace comprlsing two position and the other B, have Woven wire,

p'osition. At each corner the ree metal loop,

1 position, and also legs, 10, each of which is attached to one of the side-arms, 3, by a pivot pin and thesetlon makes it possible for both the back frame, A, and also the brace legs and rod. 10, 11, to lie flat in the same horizontal plane and within the space formed by the upward flanged sides, 2, of the bed-frame, as shown in Fig. 2.

Theseat frame, cross-bar, 13, whose journal ends, 14, have bearings in the upward-projecting flange 2, of the angle-bar frame and'side-ar1ns,;15, ex

tend from said journal ends and carry a cross-bar, 16, that has journal ends, 17, which form a joint connection with the sidearms, 15. The four sides of this seat-frame, or crossed wires, 18. ach side-arm, 15, of the seat-frame has a or hand-grasp, 19, see Figs. 1 and 4; one end of this loop has an eye, 20, through .which the side-arm, 15, extends. The other end of the loop has a flattened head, 21, whose broad flat sides are in aline- -ment with the straight handle-part of the loop and this flat-head, 21, is interposed between two similar flat-heads, 22, and, 23,

which are respectively on the ends of the side-arm, 15,

of the seat-frame, B, and the side-arm, 24, of the leg-frame, O. The jour nal ends, '17, pass through all three of the flatheads, joint or hinge is formed. 4 A metal loop, 19, is thus located at the hinge-joint which 'con meets the seat-frame, and these loo s serve as means for the hand to grasp to lift these jointed parts upward to the position shown in Fig. 1.

The leg-frame, O, has two side-arms, 24, which are' hinged or jointed, as already stated, on the journal ends, 17. This legframe also has a-cross-bar, 25, connecting thesaid two side-arms' near the hinge-joint. Thefree ends of connected by a cross-bar, 26, which has ex- B, comprises a pivoting 21, '22, and, 23, and therebv a.

B, and the leg-frame,

the two sido-a-rms, 24, are

tremities, 27, that are reduced in size; these extremities extend entirely through the ,arms, 24, and project outside of said arms,

and these notches, 28, -ormed in the upward flange, 2,

of the an le-bar frame, and thereby serve to keep the eg-frame, C, and seat-frame, B, at

' pivotin thisweight.

its horizontal flange,"1, and u ward flange,

2, and the two pivoting,cr0ssars, 6, 13, at

the center allow the three "hinged frames,'A,

B, and, G, and the brace-legs, 10, with their cr0ss-rod, '11, to, assumethe stretched out position, seeninFig. 2 Thismetal bedframe has no legs. Itmay be supported on a table or stand, and carried by attendants or I rojecting extremities engage The angle-bar bed-frame with,

placed on a truck for removal from one room to anothei in-a hospital.

Having thus described-my invention what I claim nd' desire to secure by Letters Pat- An invalid bed-frame having in combination a stationary rectangular frame; a seatframe having at one edge a ivoting bar, 13, whose-ends bear in the side-bars of said rec'- tangular frame and the opposite free edge of the seat-frame carrying a cross-bar, 16, thatv has projecting journal-ends; a leg-frame jointed on the said two journal-ends of the 35 seat-frame; and hand-grasp metal loops se cured at the said jointed parts that connect the seat-frame with the leg-frame. In testimony'whereof I afiix my signature :in presence of two witnesses.
