'Patented April 20, 1909.

Application filed March 14, 1908. Serial No. 421,178.

To all whom it may concern.

. Be it known that I, FRANKLIN L. GAINES, a citizen of the United States of America, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Invalid-Beds; and I do hereby declare the following to be a full, clear,and ,exactdescription of the invention, such as will enable othersskilled in the. art to which it appertains to make and use the same.

M invention relates to improvements in inva id beds and its object is to provide the same with various new and useful features, as hereinafter more fully described and particularlycpointed out in the claims, reference being ha to the accompanyingdrawings, in which:

Figure 1 is a side elevation of a device embodying my invention; Fig. 2 an end elevation of the same; Fig. 3 a detail of the-bolt for securing the segments; Fig. 4 a detail of one corner ofthe rigid frame; Fig. 5 a detail in plan view of portions of the jointed upper frame; Fig. 6 a detail in vertical section of the rack and pinion for adjusting the upper frame; Fig. 7 the same in horizontal section; Fig. 8 a detail in elevation, with parts broken away, of the means for elevating the lower frame; and, Fig. 9 the same in elevation at right angles to Fig. 8.

Like numbers refer to like parts in all of the figures.

The bedstead proper consists of end frames 1 connected by side rails 5 preferably made of metal tubes and having on the respective corner posts castings 2, which are extended outward a short distance and connected by a transverse tubular rail 4 mounted outside the plane of the frame to make room forthe other frames. 3 arevertical rods, which are also ofiset from the plane of the frame, inserted at the lower ends in the rail 41, bent inward at their upper ends, and inserted in the upper rail of the frame.

Near the'top of each corner post is a journal bearing 11 in which is mounted a rotative shaft 12 having its respective ends squared to receive akey for rotating the same. On this shaft, adjacent to-its respective ends are winding drums 13 on. which are wound cables 14: extending downward and attached to the respective corners of a rigid frame 6 at the middle of which frame are hangers 7 to which are pivoted the respective portions of a transversely divided frame 8,

respective corners of the rigi arise.

the respective outer ends of which frame are adapted to swing upward on the pivots connecting them with the hangers 7 and are supported in adjusted position by toothed segmerits or racks 9. These racks are connected to the frame 8 by sleeves 18 and extend downward through gear casin s 10 near the frame 6 and are engaged by pinions 21 mounted on shafts 20 extending through the tubular ends of the rigid frame, and through the gear casing of the same.

The shafts 20 are also provided with squared ends to receive a suitable key for rotating the same and the racks 9 are held in adjusted position by spring actuated bolts 19 adapted to engage the teeth thereof, and each withdrawn from the same by a cam lever 17 pivoted thereto.

The rigid frame 6 is vertically adjustable at its respective ends by winding the cables 14 on the drums l3 and is held in adjusted position by spring actuated bolts 15 extending vertically through the end frames 1 and engaging ratchets 16 mounted on the shafts 12.

In use, a canvas support is attached to and supported on the bedstead beneath the rigid frame 6. The patient can thus be raised clear'of the bed upon the canvas and to variousinclined positions thereon or lowered upon the bed proper, as occasion may It will be noted that the gear cases also serve as corner irons for the tubular frame, and that the shafts 20 are inelosed by this frame, thus preventing anything from winding thereon.

' What I claim is:

1. In an invalid bed, the combination of a bedstead, a rigid frame consisting of corner irons forming gear cases, tubular side and end railsrigidly attached to the corner irons, a frame transversely divided at the middle andhinged to the rigid frame, curved racks attached to the outer ends of the divided frameyand extending through the gear casings, pinions in thecasing and engaging the racks, shafts carrying the pinions and journaled in the corner irons and extending through the tubular end rails of the rigid frame, and means for vertically adjusting for turning and holding the shafts, cables Wound on the drums and connected to the ends of the rigid frame, a transversely divided frame mounted on the rigid frame and pivotally attached thereto and having tubular ends, racks connected to the outer ends of the divided frame, ear eases forming corner irons of the rigid frame through which the racks extend, shafts journaled in the gear cases and extending through the tubular ends of the rigid frame, pinions mounted on the shafts and engaging the racks, and spring actuated bolts engaging the racks to hold the same. I

3. In an invalid bed, the combination of a bedstead, a rigid frame supported thereon, shafts j ournaled in the end frames of the bedstead, Winding drums and ratchets on said shafts, bolts engaging the ratehets, cables i Wound on the drums, a rigid frame supported cases forming corner irons for the rigid frame, curved racks attached to the divided frame and extending through said eases, spring actuated bolts in the cases and engaging the racks, pinions in the cases and engaging the racks, and shafts journaled in the gear cases and carrying the pinions, and also extending through said tubular ends.

In testimony whereof I aliix my signature in presence of two witnesses.

FRANKLIN L. GAINES.
