spectively, which are circumposed about intermediate portion of the tubular guides 52 and 54, respectively, and which incorporates spaced clamp legs 64 and 66 including transverse internally threaded aligned bore portions receiving therethrough an adjustable clamping screw 68. The-plates 57 and 58 have juxtaposed on the outer surface of adjacent ends theerof opposite ends of an arcuate support plate 70 incorporating spaced longitudinally extending slot portions 71 which receive therethrough the bolt portion of wing nut and bolt assemblies 72 extending integral from the outer surface of thexa'djacent ends of the arcuate plates 57 and 58. Relative longitudinal movement between the plates 57, and 7t? may be obtained to accommodate the lordosis pad assembly to different size patients. Suitably secured on the outer surface of the plate member 70 is an internally threaded support sleeve element '74 through which extends a threaded adjustable shaft member 75 whichextends through a suitable aperture in plate "/6. A suitable adjusting handle '78 is secured on the outer end of the shaft '76, the opposite end of said shaft 76 having secured thereon a suitable abutment pad 80 for engaging an intermediate portion of the spine and being adjustable toward and away from the spine by manipulating the handle 78 for effecting and forward convexity of the spine of the patient.

Indicated generally at 82 is an upper or movable belt assembly comprised of a pair of arcuate plate members 84 and 86 .which respectively include overlapped end portions 88 and 90 each of which including aligned longitudinally extending slot portions through which an adjustable wing nut and bolt assembly 92 extends. The plate elements 84 and 36 are suitably padded at M and 96 at their terminal ends and have integrally secured thereto flexible belts 98 and we, respectively, the belt 98 including a plurality of longitudinally spaced openings or aperture portions 102 engageable with a suitable buckle assembly We on the flexible belt 100. The upper belt assembly 82 will be circumposed about an upper waist portion of the patient P, and as will subsequently become apparent force transmitting rods are provided wherein the upper belt assembly 82 will be moved to the dotted line position shown in Figures 1 and 2 applying traction to the spine of the patient.

The plate elements 8 and 86 have suitably secured on an outer surface portion thereof laterally extending clamp sleeves 166 and 1%, respectively, which incorporate a transverse threaded portion receiving therein a clamping screw 110 which is engageable with an intermediate portion of a force transmitting rod 112 and 114 which may be vertically adjusted in the clamp sleeve elements 196 and 103 in which they are respectively supported, being adjusted by manipulating said clamp screws lit). The force transmitting rods 11?; and 114 are telescopically received within the tubular guides 52 and 54, respectively, each of said rods including on the outer surface thereof longitudinally disposed gear rack portions 116 and 118, respectively.

The tubular guides 52 and d incorporate on the upper .ends thereof means for extending and retracting the force transmitting rods 112 and 314 within the tubular guides 52 and 54, respectively, said means being indicated generally at 120 and 122, being identical, and accordingly only one of which being described in detail.

The tubular guides 52 and 54 incorporate in the upper ends thereof a diametrical notch portion 124, see Figure 7, and has secured on opposite sides of said notch portion leg portions 126 and 123 of a support bracket indicate-d generally at 130. Extending transversely and journaled in aligned aperture portions in the leg portions 126 and 128 is a support shaft 131 which has secured on an intermediate portion thereof a gear element 132 which is interengaged with the gear rack 118 of the force transmitting rod 114. Secured on the outer end of the shaft 131 is a suitable handle member 134 which may be rotated for extending and retracting the force transmitting rod 114. It is to be understood that similar structure is incoprorated in the adjusting means 120 for the purpose of adjusting the force transmitting rod 112.

The leg portion 126 of the support bracket 130 includes an integral plate portion 136 extending toward the leg portion 128 and has extending through a suitable internally threaded bore portion a hand manipulable threaded screw element. 138. which extends through a lower transverse internally threaded bore portion 140 of a latch lever 142 which is intermediately pivoted at 144 on the outer surface of the leg portion 128. The lever 142 includes a dog portion 146 which is engageable with a toothed wheel element 148 fixedly secured on the shaft 131 in alignment with the latch lever 142. By manipualting the screw 138 the dog portion 146 of the latch lever may be urged into engagement with the toothed wheel 148 thus preventing adjusement of the force transmitting rods, and retaining said rods in a fixed position after traction has been imposed upon a patient upon which 4 the apparatus is disposed. The mechanism of Figures 7 and 8 will permit the apparatus to be selectively adjusted to vary the amount of traction or force applied on opposite sides of a patient, thus proving useful in the cases of disc-herniation, when a patient is inclined to be bent toward one side or the other.

It will be observed that the patient may still have the ability to walk about even after the traction apparatus has been applied.

The foregoing is considered as illustrative only of the principles of the invention.
