This invention relates to physiotherapeutical apparatus and it has particular reference to a machine for restoring to normal relationship the bones of the pelvis and spine.
The principal object of the invention is to pro.- vide a table adapted to support a patient in a reclining position, combined with suitable mechanism effective to propel the table longitudinally while at the same time elevating the same as it moves in a footwardly direction, without deviating from the horizontal plane. Following a short pause, the table is caused to reverse its direction of travel, during which it recedes to its starting level and is stopped more or less suddenly by suitable brakes or snubbers.
Another object of the invention is to provide a sacro-iliac, spinal and visceral adjusting table on which are adjustably positioned opposed cush=- ions, which are adapted to bear against the reclining patients body above the hips and thus stabilize the lower position of the body. Thus, as the table is interrupted in its headwardly and downwardly course, the inertia carries the sacrum to the posterior and superior, elongating the spine and raising the viscera, due to the fact that they are in motion while the hips are stopped with the movement of the table. By correcting the position of the pelvis and spine, nerve pressure occasioned by these incorrect positions is alleviated, thus restoring normal function of the affected organs. By adjusting the entire spine and all viscera simultaneously, a greater degree of correction is attained.
Still another object of the invention is to pro.- vide a method of restoring to normal function the spinal nerves by subjection the relaxed body of a patient to longitudinal reciprocal motion and interrupting the motion suddenly in a head-- wardly direction while yielding the sacrum to inertia to effect elongation of the spine.
Other objects will become manifest as the description proceeds, taken in connection with the annexed drawing wherein Figure l is a top perspective view of a machine constructed according to the invention.

and pinion for raising and lowering the leg support through the medium .of the adjusting means shown in Fig. 6.
Continuing with a more detailed description of the drawing, reference numeral l0, denotes generally the supporting framework for the adjusting table II, which latter is reinforced preferably by an angle iron'frame l2 on its underside.
Depending from the underside of the table and in spaced apart relationship at each end thereof is a series of plates l3 which are in fixed perpendicularity to the table surface through the medium of brackets 14 .(Fig. 5). The lower edges of these plates are each deflected at an angle of approximately 13 and these edges are welded or otherwise suitably secured to rods l5 which are coextensive with the plates.
Immediately below the pair of plates H3 at each end of the machine is a transverse shaft I6 whose ends are journaled in bearings I! afiixed to the underside of the upper horizontal rails l8 of the machine frame I Of The shafts [6 each carry a pair of loosely mounted peripherally grooved rollers 19 and in the grooves of these rollers rest the rods l5 of the plates !3. Thus, the table II is supported on its framework in such manner that'during longitudinal displacement thereof, effected in a manner to be presently described, the table will be raised as it travels footward and lowered as it travels headward without deviating from the horizontal plane.
To actuate the table II in the manner set forth, an electric motor 2!] is mounted in the frame at the rear end thereof and, through a speed reducer 2i, drives a shaft 22. The shaft 22 carries a sprocket wheel 23 on which is a chain 24, engaging'a sprocket 25, mounted on the shaft I 6' at the rear .of the machine.
In Fig. 5 is shown a semiacircular earn 2% .which is secured, as by welding, to the rear shaft 16 and thus is rotated as the shaft revolves. The lobe of the cam is brought successively against a plate 27, affixed to and depending from In this manner, the table is moved in a footward direction, being elevated simultaneously through the inclined supporting plates l3.
As the tip of the cam 26 rides off the of the depending plate 21, to the action of gravity lower end the table is released and the direction of travel is reversed. Forward or headward movement of the table is stopped more or less suddenly by means of a snubber consisting of a semicircular shoe 28 at the forward end of the machine and which is affixed to the frame 10 with its curved surface directed rearwardly. A flexible strap 29 is adjustably attached to a plate 30, depending from the forward end of the table II, through the medium of a threaded eye-bolt 3|. The strap 25 is passed over the curved surface of the shoe and its opposite end is secured therebelow to the machine frame at 32.
As the table l l travels in a forwardly direction, the strap 29 frictionally engages the shoe but to minimize the shock of impact, a coil spring 33 is attached at one end to the strap at 34 below the shoe 28 and at its opposite end to the depending plate 31]. This spring also is effective to remove slack in the strap.
Mounted forwardly of the midsection of the table II is a pair of spaced apart hip retaining pads or cushions 35. These pads are adjustable transversely of the table by virtue of separate mountings 3E, slidable in a transverse space provided in the table therefor. The mountings are supported for sliding movement on a transverse plate 31, and each mounting is recessed to retain a block 38 (Fig. 4). The blocks are each bored and threaded to receive a screw rod Eli which latter has left and right hand threads. A crank M! is provided on one end of the screw rod 39 and at one side of the machine for rotating the rod to thus move the pads 35 relative to each other and to adjust the same to the hips of a patient reposing on the table top.
To support the legs of a patient in an elevated position, when required, a platform ii is disposed for vertical adjustment with respect to the table at an appropriate point spaced rearwardly from the hip pads 35. A vertical plate 42 supports the platform M at its upper end and extends through a transverse slot .3 in the table top. Opposed guide blocks A l, affixed to a crossmember 45 (Fig. 6) under the table, have confronting grooves 45 in which slide the vertical edges of the supporting plate 32.
To each vertical edge of the supporting plate 42 is aihxed a rack bar 4 the teeth of which are engaged by pinions Q8, mounted in spaced relationship on a transverse shaft 42, the latter being extended at one side of the table I! to carry a crank 56. A circular housing 56 is affixed to the shaft t9 and has thereon a series of an nularly spaced bores, which are adapted to reg ister with recesses in a mounting plate 52. A
lock pin 53 is disposed in one of the bores of the circular housing and is movable perpendicularly to the mounting place and receivable selectively in the recesses of the latter to lock the shaft 49 against rotation and thus hold the leg rest 4| in vertically adjusted positions.
It is clearly evident from the foregoing that when a patient is lying prone on the table with the hips in contiguity with the pads 35, the sacrum will be disposed over the U-shaped opening 54 in the table top at the midsection of the transverse space accommodating the pad mountings 36. It is preferred that the legs of the patient be elevated by raising the support M so that more freedom is allowed the upper portion of the body and for greater relaxation.
The motor 28 is energized to effect rotation of the shaft I6 carrying the cam 26, thus causing the table to reciprocate as explained. Since the hips are held by the pads 35, sudden stoppage of the table in its forward movement will, through inertia, cause the sacrum to be carried to the posterior and superior and elongation of the vertebral column. Due to the fact that the viscera are in forward motion when the table is stopped, they are raised towards a more normal position. As a consequence, the nerve strain and stress occasioned by incorrect position of the pelvis and spine are relieved, making possible more ready restoration of normal function thereof.
Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claims is also considered to be within the spirit and intent of the invention.
