SPECIFICATION forming part of Letters Patent No. 662,477, dated November 27, 190-0. Application filed November 17, 1899. Serial No. 737,290. (No model.)

To all whom it may concern:

Be it known that I, CHARLES B. ULRIcH, a citizen of the United States, residing at Duluth, county of St. Louis, State of Minnesota, have invented a certain new and useful Improvement in Lifting Devices for Invalids; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a lifting device for lifting invalids, and is designed for raising an invalid off from a bed in a reclining or sitting position, whereby the patient may be moved 0E from the bed to air the bed or to make up the bed, to rest the patient, to transfer the patient to a chair or to the bath-room or out of the room in order to air the room, or to transfer the patient to an operating-roo1n. The device is also adapted to raise the patients into position where they may take slight exercise, as by swinging back and forth with their feet upon the floor; also, to facilitate the use of a bed-pan, to roll the patient from side to side, and to handle the patient.

generally without exertion of the patient, the device being readily operated by an attendant. The device or portions thereof may also be made removable when not in use, or parts thereof, as the track, may be permanently located.

My invention consists of the combination of devices hereinafter specified and claimed, and illustrated in the accompanying drawings, in which-- Figure 1 is a view in perspective. Fig. 2 is an enlarged View in side elevation. Fig. 3 is a view in section through the track. Fig. 4 is a detail view of a removable crane to 7 support the track. Fig. 5 shows a perforated blanket. Fig. 6 illustrates a modification in the construction of the blanket. Fig. 7 is a reduced plan view of the foot of the crane.

More particularly my present invention is designed as an improvement, as respects certain features, over a device of this class for which United States Letters Patent were granted to me June 2, 1896, No. 561,363.

Any suitable track (indicated at a) may be employed,the same being engaged,preferably, upon the ceiling of a room, as in a hospitalward, for example. Wheels 0 are arranged to travel upon the track, said wheels mounted upon an axle d, with which is connected a pulley 6, over which is passed a lifting-ropef. A lifter-bar g is provided with a drum it, said drum made rotatable by suitable gear o, whereby the lifting-rope may be wound upon said drum. The lifting-rope is also passed over a pulley attached to the lifting-bar at one side the drum, and preferably also over an additional pulley 0, attached to the lifterbar on the opposite side of the drum. The gear is actuated by a crankhandle It, a pawl Z being employed to hold the gear in fixed position. This lifting-bar, with its attachments, is suspended over the patients bed upon the track. The lifting-bar is provided with a series of cross arms m, having depending cords n at their extremities, each of said cords being preferably provided at their lower extremities with a snap-hook at 19. A canvas or blanket q is employed to be placed under the patient, provided at its lateral edges with rings 7 to engage the hooks upon the ends of said cords. The blanket may be constructed in a variety of ways and of various materials. Where it is desired to give a patient a bath, a perforated rubber blanket may be employed. (Indicated in Fig. 5.) To facilitate the use of a bedpan, a shorter canvas is preferably employed, provided with an elongated slit, (indicated at s, Fig. 6,) an additional depending cord or rope t being engaged with the lower end of the lifting-bar and with the canvas intermediate its lateral edges to hold the canvas from spreading unduly adjacent to said slot.

I prefer to mount the drum upon which the lifting-rope is wound upon a bracket (indi-' cated at u) rigidly secured to the lifter-bar.

If the ceiling is high, a suspending rod or cable 3 is employed to connect the axle of the wheels with the upper pulley. In operation the lifting-bar, with its attachments, is moved on the track over the patient and the cords depending therefrom are engaged with the canvas or blanket placed under the pa IOO tient. Then by means of the gear engaged with the drum the lifting-rope is wound, thereby lifting the patient, when he may be transferred upon the track, as mentioned.

The track may extend upon the ceiling across a hospital-ward, so that the lifting device may be moved over any patient therein.

The pulleys j and 0 are perfectly engaged with the lifting-bar by means of swivelsw or their equivalent. The axle d of the wheels 0 may be provided with a depending hooked arm n to engage the rod y or the pulley 6'.

Where the track a is attached to a ceiling, supporting-brackets 2 are employed. The track shown in the drawings is constructed with an inclosing body channeled on its under side and provided with flanges projecting into the body, the wheels 0 traveling in the ways formed at the sides of said flanges.

Instead of a track a a crane b may be employed. The crane b is constructed with a hollow base-section (indicated at 1) engaged upon a supporting-foot of angle-iron or otherwise. Into the hollow base-section is telescoped a section 2. The section 2 carries a lateral arm 4, upon which the lifter-bar is suspended. A brace 5 is shown bracing the arms upon the adjacent section. The crane may be readily placed at the end of the bed and is readily removable from the room. The arm 4 may be swung laterally in the basesection 1, so as to carry the patient away from over the bed. The foot of the crane may consist of three radiating parts 15. (Indicated more particularly in Fig. 8.) The lifting-bar g is provided with a series of perforations in order that the pulley j may be adjusted into desired position, so that the center of gravity may be changed as required. The pawl l is preferably in the nature of a spring-pawl. The pawl may be operated from any desired position to disengage it from the adjacent gear. I prefer to attach to the pawl a rod 7, extending longitudinally of the bar 9 toward the head thereof, so that it may be readily operated by the attendant. Where it is desired to securely hold the liftingbar g from tilting longitudinally, a rod or cord 8 may be employed, connected with the pulleye and with the forward end of the lifting-bar g.

The suspending-cords 01 preferably pass through the ends of the cross-arms and ex tend across the top of said arms, so that if by any possibility the corresponding arms should breakthe cord will be sustained upon the lifting-bar and prevent-the patient from dropping.

The addition of the pulleyo materially assists in guiding the rope while the patient is being turned from one side to the other, the turning being readily accomplished by tilting the lifter-bar in the proper direction.

In using the crane b I prefer to attach the pulley e permanently to the outer end of the frame, which may readily be done by bolting the rod 1) to the arm 4, as indicated at 19, Fig. 4.

The pulley o is employed as a guide-pulley to keep the rope from winding against the side of the drum when the patient istilted or when the lifting-frame is tipped to one side.

By the use of this additional pulley the rope will not wind against the side of the drum when letting the patient down.

By providing the pawl with a rod 7, extending longitudinally of the lifting-bar toward,

the head of said bar, the pawl may be released by the hand of the attendant at the head of the frame, while with the same hand the lifting device may be steadied at the same time, the other hand being employed to operate the drum.

What I claim as my invention is- 1. In a lifting device, the combination of a support-,a lifting-bar, a series of cross-arms engaged therewith, a pulley carried by said support, a pulleyj attached to the lifting-bar, a guide-pulley 0 attached to the lifting-bar,
