APPARATUS FOR MOVING INVALIDS.

SPECIFICATION forming part of Letters Patent No. 505,654, dated September 26, 1893.

Application filed June 27, 1892. Serial No. 488.084. (No model.)

To ctZZ whom it may concern:

Be it known that I, SETH P. H. HALE, of Williamsville, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Moving Invalids, of which the following is a specification.

This invention is an improvement upon that for which Letters Patent No. 430,642 were granted to me June 24, 1890; and the invention consists in the improvements hereinafter described, whereby the convenience and efficiency of said apparatus are increased.

Of the accompanying drawings, forming part of this specification: Figure 1 represents a side elevation of my improved apparatus, a portion thereof being omitted. Fig. 2 represents a top View of the apparatus, and a section on line 5-5 of Fig. 1. Fig. 3 represents a rear elevation of a part of the apparatus.

The same letters of reference indicate the same parts in all the figures.

In the drawings: a represents an upright tubular standard, having a suitable base a to rest on the floor of a room. On the upper end of said standard. rests a nut b, having a hand-wheel b by which it may be rotated.

0 represents a threaded standard or screw, passing through the nut b and engaged with the thread thereof, the lower portion of said screw being within the tubular standard a, while its upper portion extends above said standard and is provided at its upper end with a flatbearing-plate 0', adapted to bear. against the ceiling of a room when the screw 0 is sufficiently raised. The standard a and screw 0 constitute an elongated jack-screw, adapted to be firmly supported in a vertical position by engagement with the floor and ceiling of a room, as described in my above-mentioned patent.

01 represents a sleeve, which is mounted to turn freely upon the standard a, and is supported on said standard by means of a vertically-adj ustable collar 01', affixed to the standard by a set-screw 01 the sleeve 61 hearing at its lower end against said collar, so that the sleeve and the crane hereinafter described supported thereby, may beheld at any de sired height by adjusting said collar vertically. I

6 represents a horizontal arm, having atits inner end a collar 6', which surrounds and is affixed to the upper end of the sleeve (1. The outer portion of said arm 6 is supported by an inclined brace 6 the lower end of which is provided with a collar e affixed to the sleeve 0?; while its upper end is affixed to a block e which is attached by a set-screw e to the arm 6. The collars e and e are preferably confined on the sleeve 61 by means of collars e 6 affixed to said sleeve by means of set-screws.

f represents a platform or frame, affixed to the lower portion of the sleeve d.

f represents a horizontal rod or shaft, which passes through the frame or block f, and has loosely mounted upon it drums or pulleys q q and r 7', which are independently rotatable.

On the drums or pulleys q q are wound straps g g, and on the pulleys or drums rrare wound straps h h, said straps passing from said pulleys over loose supporting pulleys on the arm or crane e, the arrangement of the pulleys and straps being substantially similar to that shown in my above-mentioned patent, the free ends of the straps being connected with a jointed couch or chair, which may be of the construction shown in my former patent, or of any other suitable construction, the said jointed construction being preferred because it enables the couch to be converted either into a chair or into aflat support, by suitably operating the drums, as described in said patent.

To the drums q q are vattached gears u a, which mesh with pinions c 'u on a shaft w, journaled in the frame or block f. Similar gears w a: are attached to the drums r r and mesh with pinions y y on another shaft-z, which is also journaled in the frame or block f. By rotating the shaft w, the straps g g are operated, while the rotation of the shaft 2 operates the straps h h. Said shafts w a are provided with cranks A A whereby they may be rotated. The shafts w a may be held in any position by brakes B B (Fig. 2), which are engaged with screw-threaded rods 0 0, adapted to rotate in lugs formed on the frame or block f, the threaded ends of said rods entering tapped sockets in the brake shoes. By turning said rods 0 in one direcagainst rotation.

tion, the brake shoes are pressed against the shafts w 2 so firmly as to prevent said shafts from rotating. The said mechanism for independently rotating and for arresting the rotation of the drums is substantially the same as that described in my above-mentioned patent.

To enable the operator to temporarily lock the drums and prevent movement of the straps while he is engaged in adjusting the apparatus, I provide two dogs 2 2, which are mounted to swing loosely upon the shaft w, and are adapted to engage the teeth of the gears 50 and a. To said dogs is connected a cross-bar 3, which is normally held in araised position by a spring 4:, encircling the sleeve d, and bearing upon the block or frame f, said spring normally holding the dogs 2 2 out of engagement with the gears a: and u. The cross-bar 3 is connected by arms 5 5 and a rod 6, with a treadle 7, adapted to move vertically upon the standard a, and located within convenient reach of the foot of a person standing by said standard, so that the operator, by depressing the treadle, is enabled to throw the dogs 2 2 into engagement with the gears :20 and it, thus locking the gears and the drums When the treadle is released, the dogs are raised, so that the apparatus is adapted to operate as already described.

The employment of the sleeve d and the attachment of the frame or block f and the arm or crane e and its members 6 to said sleeve, enable the arm or crane and the strapoperating mechanism to be readily swung horizontally to any desired extent, the sleeve constituting a connection between the crane and the block or frame f, which insures their moving horizontally in unison.

The sleeve 11 is an important improvement, which I have added to the apparatus as shown in my former patent.

I claim The combination of the telescopic standard, the sleeve rotatable on said standard, and resting on a collar ad j ustably secured to said standard by a set screw, the crane or arm and the frame or block, both mounted on said sleeve, the strap-holding drums mounted on a rod or shaft supported by said frame and provided with gear wheels, the spring supported dogs adapted to engage and lock said gear wheels, a treadle arranged to be depressed by the operator, and connections between said dogs and treadle whereby the dogs may be caused by the operators foot to lock the gear wheels and drum, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 13th day of June, A. D. 1892.

SETH P. H. HALE. Witnesses:

J AMns CHESTER BROWN, WILLIAM R. SPOONER.
