1,008,500. Ptented Nov. 14,1911.



-an improved brace of this character, which shall be efficient in its use, to perfectly and conveniently relieve the greater part of the strain on the muscles of the'back when assuming a stooping posture.

The invention is embodied in a novel arrangement and construction of parts, as will be, hereinafter described and as is shown in the accompanying drawings, in which- Figure 1 is a perspective of the back brace as applied to a workman, and Fig. 2 is a plafi view of the brace.

Reference being bad to the drawings, in which similar reference characters indicate similar parts, ll-indicat'es a seat-pad, which is made bf wood or other material, having suitable padding, and which is of such a contour to perfectly fit over the hips of the wearer without discomfort. This pad or seat 11 is suspended from a belt '9 by two straps 10, which straps 10are securely fastened to both the belt 9 and seat 11.

To the lower end of the-seat are pivoted right and left hand hinge members 18 by brads or pins 19, which allow the hinges-to swing'in the plane of the seat, and to the said hinges are pivoted, by pins 13, the leg strips 1-2, which are arranged to swing forward and backward on the pins 13. Thus a. universal joint is established between the legstrips 12 and scat 11. The said leg strips 12 are of wood, or other material, suitably padded, and have at their upper ends straps 14 and 15, and at their lower extremities sockets 20 to which are fastened straps l7 and 16. The straps l t and [5 are arranged to buckle together around the upper end of the-thigh of the wearer, and the straps lo and 17 are arranged to engage the lower end of the thigh, above the knee, to securely hold the leg strips 12 in place on the rear of the l 1- IBAGK-BRACE.-

thighs of the wearer. lhcn with the aid of the belt 9 and straps J to hold up the seat, the seat couvenientl' held in positiogngon the wearer, and the universal joints between the seat 11 and leg st] ips 12 allow for the unrestricted use of the legs and feet of the wearer.

To the seat 11 is fas cued a flat spring 6, which extends up the back of the wearer, and which has a loop 5 uounted on its upper end. The extremity of the back-spring 6 is bent around the loop 5, to allow the loop to swing longitudinally tl ereof.

A backpiece 3, of sift leather or other material, is mounted on the back of the wearer by means of shoulder-steps 7 extending from the up er corners thereof, adapted to pass over t 1e shoulders of the wearer to buckle witl straps around the arm-pits anl which are secured to the lower corners (f the back-piece 3. This back-piece 3 has an upstanding looped portion 4, with which t. ie loop 5 engages to connect the backiece3 and the back-spring 6'. The portion 0 the 10 p 5 passing beneath the loop! is curved, th s' allowing for suitable movement of the b: elf-piece 3, to allow for the free movement 0 the body. a

In use, the spring 6, having a backward tension, relieves the g 'eatcr part of the stress on the muscles 0 the wearers back when assuming a stoopi rig posture, and by means of the loop 5, tiespring does. not touch the wearer-when stoopin-g, to incon venience him, but the 31 ll is directed solely to the back-piece. The strain is therefore concentrated upon the s at- 1l,to the relief and c nivcnicnce of they carer. The seat 11 being of such a contour to perfectly [it the hips of the wearer, also 1 rov ides for greater ease to the wearer, and makes the device more cflicicnt in its use. The means shown .for holding the seat in position also pro VIdOS for greater case an id eiliciency of the device.

It is also understood l hat various alterations and additions can we made to the device within the scope of ti o appended claims, and it is not desired to the specific (2UllSll'll(.'ll(ll described and shown.

l huing described my invention, what- I claim as new is:

l. The combination wi ha scat pad having a waist belt attached thereto and meansfor securing the pad to lie lower limbs, of

imll the device to 'a heck piece and pairs of strap sections extending rom diagonally opposite corners thereof, a at spring member attached to the seat pad, and a loop loosely connecting the free end of the spring and the back piece.

2. The combination with a seat pad having at waist belt attaohed thereto, flexible leg strips loosely connected to the lower end of the pad and provided with attaching straps, of a back piece and pairs of strap sections extending from diagonally opposite corners thereof, a fiat spring member attached to the seat pad, and a loop loosely connecting the free end of the spring and the back piece. 15 In testimony whereof I aflix my signature in presence of two witnesses.
