FREDERICK M. OLIVER, OF PEN DLETON, OREGON.

APPARATUS FOR USE IN HOSPITALS, SICK-ROOMS, AND LIKE PLACES.

To all wh m it-m/ay concern:

Be it known that I, FREDERICK M. OLIVER, acitiz en of the United States, residing at Pendleton, in the countyof Umatilla and State of Oregon, have invented certain new and useful Improvements in Apparatus for use in Hospitals, Sick-Rooms, and Like Places, of which the following is a specification.

The invention relates to an apparatus for use in a sick-room, operating-room, hospital, and like places where it is desirable to lift and support an injured or sick person from a bed and, if necessary, move the patient entirely from the vicinity of the bed.

The object of the invention is the produc tion of an apparatus such as described which shall be simple, light, and strong in construction and which can be easily and noiselessly manipulated by a single operator.

The invention will first be described in connection with the accompanying drawings and then pointed out in the claims.

In the drawin s, Figure 1 is a perspective of the device. ig. 2 is an end elevation of the lifting-tongs, showing a patient in position to be moved. Fig. 3 is a front elevation illustrating one gear and contiguous parts of the hoisting mechanism. Fig. 4 is an end elevation of the same. Fig. 5 is a broken front elevation showing the means of locking the two members of a lifting-tongs together. Fig. 6 is a broken section of Fig. 5 on line a a.

Referring to the drawings, in which like numerals of reference indicate like parts thro ughout the several views, 1 denotes a suppotringframe comprising standards 2 and 3 and crossbar 4, revolubly mounted in bearings 5 of said standards.

Properly spaced and securely attached at one end to cross-bar 4 is a pair of depending straps 6, provided with attaching-hooks 7 at the opposite end.

8 denotes a pair of lifting-tongs comprising the usual two members hinged together at 9, the shank 10 of both members being cut away for a portion of their length. to provide shoulders 11. Depending lugs 12, integral with tongs 8, are adapted to receive handlebars 13 to enable the tongs and their load to be carried from place to place when detached from the straps.

Locking-bars 14, provided with eyes 15, adapted for removable engagement with hooks 7, are pivoted at 16 through enlarged heads 17 to the shank of one member of the Specification of Letters Patent.

Application filed June 20, 1905. Serial No. 266,116.

tongs to provide for movement of said bars inlocking the tongs in closed position. When, the tongs are closed and the locking-bars are swung on their pivot connection with one shank to upright position, as shown in Fi 6, toes 18 of said bars overlie the other shan of their respective tongs and prevent said tongs opening until the bars are swung down to the position shown in dotted lines in said figure, the heels 19 being of such dimensions as to then he clear of said shank and allow it to swing to open position, as shown in Fig. 2.

Two series of slats 20 and 21, properly spaced apart, are rigidly secured to the inside of tongs 8 and provide a light strong stretcher for the support of the patient. A sprocket-wheel 22, securely aflixed to the end of cross-bar 4, is connected, by means of endless chain 23, to a smaller sprocket-wheel 24, revolubly mounted on standard 3. A crank 25, rigidly attached to sprocket 24, provides means for revolving sprocket 22, and thus of course raising or lowering the stretcher. A ratchet 26, fixed to sprocket 24, is normally engaged and held against reverse rotary movement by pawl 27, held to its seat by spring 28, disengagement being effected by pressure on thumb-plate 29.

In using the apparatus the stretcher is elevated, by means ofthe crank, to a position just above the patient and held there by engagement of the ratchet and pawl. The locking-bars are swung down and the stretcher opened, when the patient is rolled by means of the bed-sheet and the stretcher lowered and one half placed under him. The patient is now rolled to the other side and the other half of the stretcher placed in position. The locking-bars are then swung to upright posi tion, being retained there of course by the weight of the patient, who can then be raised from the bed or removed to another part of the room, as desired, the frame being provided with casters, preferably of rubber, to

obviate noise, as shown.

It is well known with what difficultv a sick person or invalid is manually removed from a bed without inconvenience to the patient when such is desirable for the purpose of remaking the bed or airing the room, &c., and it is obvious with what ease and convenience such work can be accomplished by a single operator by the aid of my apparatus, without which two or three attendants would be necessary to perform the work.

Having thus described my invcntion,what I claim as new, and desire to secure by Letters Patent, is

1. In an apparatus of the character described comprising a framework including a revoluble shaft, means for revolving said shaft, means for locking said shaft against movement in one direction, straps connected with said shaft, frame-carrying tongs connected with said straps, each of said tongs includin two members pivotally connected, each 0 said members being formed with a reduced end, and a locking-bar pivoted to one of said members and arranged for connection with the strap.

2, In an apparatus of the character described comprising a framework including a revoluble shaft, means for revolving said FRED. M. OLIVER.
