FRACTURE APPARATUS FOR STRETCHING PARTS OF THE HUMAN BODY.
To all whom it may concern:
Be it known that I, hIAX KOEHLER, physician, a subject of the King of Prussia and German Emperor, residing at Hohenlohehiitte, in Oberschlcsien, Germany, have invented certain new and useful Improvements .in Fracture Apparatus for Stretching Parts of the Hum an Body, of which the following is a specification.
The present invention refers to an arrangement for stretching the human body on a bed by means of the weight of the body itself.
In order to always keep the body in a horizontal position the bed movable in longitudinal direction was arranged on an adjustable inclined plane, and the horizontal position was obtained by an arrangement provided opposite the ways allowing of a vertical adjustment. This arrangement was however too complicated for sick-beds. Instead the movable bed is supported on four rollers on parallel levers arranged in pairs on both sides of the bottom frame, which levers form inclined planes and can be adjusted by a mutual tightening and adjusting gear so that the bed will always remain. in ahorizontal position.
In the accompanying drawing the new arrangement is exemplified in side elevation.
To the horizontal beam -a of the bed frame is revolubly secured by means of hinges cc on each side of the bed a pair of levers b-l). The levers l)b form an inclined surface which is limited at either end by semicircular portions dd*- and e-e respectively. Beyond the pivoting points -ccthe levers l) l are extended and coupled together by means of rod g. The latter is again coupled with a long tubular nut hin which turns a screw spindle i-. Screw spindle iis secured against axial movement by two collars in. the bottom part of the bed frame and provided with a handwl1eel-7r-. By turning said hand-wheel 7rthe levers b l) are adjusted and thereby also the bed m resting on rollers 0 -0 011 these levers.
Specification of'Letters Patent.

Serial No. 368,755.
The bed m can be arranged in such a manner, that it is made with its lower parts folding, which may be adjusted and secured in vertical direction in known manner. If new the bed at is loaded with the body to be stretched and the body is fastened with the limb to be stretched to the hook n of the bed-top, the bedv 'm will always tend to roll down the inclined planes of the lovers, and in consequence the bed will exert by itself a pull on the body resting thereon and thereby stretch the limb.
It is understood that this device is to be used for stretching various parts of the body at will.
Having now described my invention what I claim and desire to secure by Letters Patent of the United States is:
1. In a fracture apparatus the combina tion of the bed carrying the rollers, with the parallel levers pivoted to bars upon both sides of the bed frame, substantially as described.
2. In a fracture apparatus the combination of the bed carrying the rollers, with the parallel levers pivoted to bars upon both sides of the bed frame and with the adjusting gear to regulate the height of the bed and retain it always in a horizontal position, substantially as described.
3. In a fracture apparatus the combination of the bed carrying the rollers, with the parallel levers pivoted to bars upon both sides of the bed frame and with the adjusting gear to regulate the height of the bed and retain it always in a horizontal position, all the various parts of device being detachably connected to each other, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two Witnesses.
