J. S. SOHMITT. INVALID BED.

{1310. 557,614. Patented Apr. '7, 1896.

UNITED STATES PATENT ()FFICE.

JOHN SIGMUND SCIIMITT, OF NEV YORK, N. Y.

INVALID-BED.

SPECIFICATION forming part of Letters Patent No. 557,614, dated April 7, 1896.

Application filed January 3, 1896.

To all whont it nmy concern.-

Be it known that 1, Jon): Srennxn ScHinTr, a citizen of the United States, residing in New York, in the county and State of New York, have invented certain new and useful Improvements in Invalid-Beds, of which the following is a specification.

My invention relates to beds and chairs; and it consists of an invalid bed or chair for invalids use from which a portion of the mattress (or cushion) can be removed by a lever combination arranged on an oscillating shaft and at the same time a vessel or receptacle for the excretion of the invalid lifted in the opening thus created.

In the accompanying drawings, forming part of this specification, Figure 1 is a side elevation of a bed, a part thereof being shown in section to disclose the arrangement of the parts comprising my invention. Fig. 2 is an enlarged sectional view showing details of construction. Fig. 3 is an enlarged cross-section on the line 3, indicated in Fig. 1. Fig. at is a sectional elevation showing the modified construction of my invention as adapted to an invalids chair.

Similar letters of reference in all the views indicate corresponding parts.

The mattress 13 in my improved invalid-bed has in the place where normally the lower end of the body will lie a hole I) about eighteen inches square. The hole is lined with waterproof material, and on the sides are fastened segmentally-curved rails 6, extending downward toward the foot of the bed to the cross-piece a, to which their ends are secured. The sides of the hole Z) toward the ends of the bed are correspondingly arcuated to admit the spherical motion of the bowl 0 and to allow the sliding cushion C to pass along on the rails in and out of its place in the mattress.

Sliding cushion C is fastened to plate (Z, gliding in rails e and connected by chains f g to levers h, rigidly secured to shaft 1. Plate (Z is made, preferably, of spring-steel an d curved on the same radius as the rails e.

To the same shaft I are also rigidly secured the lifting-levers 7:, provided with hooks Z at their ends, holding the trunnions m of ring 12, supporting bowl 0. These levers are so placed in relation to levers 71 that when the sliding Serial No. 574,257. (No model.)

cushion C is in its place, filling the hole in the mattress, the receptacle 0 will be in its lowest position, and again when cushion C is pushed out of its place in the mattress and the hole opened the bowl 0 will be moved in its place and elevated to the level of the mattress.

The shaft I is pillowed in bearings secured to the frame of the bedstead A, and to its squared ends is fitted removable operatinghandle 1), conveniently long and adapted to be, when set on the shaft, in a suitable position within reach of the patient, and as all parts of the apparatus are made to move with greatest ease he may effect the change in the apparatus himself. Mattress B is fastened to the bedstead A to insure a smooth working of the apparatus, because when the shaftis turned the levers tend to move the mattress on the bedstead.

In Fig. 4 I have shown a modified construction of my above-described device adapted for invalid-chairs. In this instance the rails r are bent on the arc of the circle having the shaft for its center, and the bottom 3 of the removable cushion t is also bent on the same circle. This is necessary because a chair is, in proportion to its length, much higher than the bed, and therefore if a flatter are were used the cushion, when removed from its place, would necessarily project in the rear of the chair. The chains f and g are in this case not needed and levers h are attached directly to the plate s. In all other respects the construction is the same in its general features as the above-described bed.

I claim and desire to secure by Letters Patent- An invalid-bed, comprising a bedstead, a mattress,secured thereon and having an opening in the place where the lower end of the body of the invalid normally lies, curved rails, secured to the sides of said opening, and extending downward toward the foot of the bed, a sliding cushion, adapted to fill the opening in the mattress, a curved plate, secured to the sliding cushion and adapted to slide in the rails; an oscillating shaft, pillowed in hearings in the bed-frame, levers, rigidly secured to said shaft, chains connect ing the levers to the plate, carrying the sliding cushion; hooked levers, also rigidly secured to said shaft and adapted to carry a redescribed in the foregoing specification I have eeptacle into the opening in the mattress, signed myna-me in the presence of two sub- When the sliding cushion is removed therescribing witnesses.
