PATIENTS ADJUSTABLE TABLE.

T 0 all whom it mag concern Be it known that we, JOHN B. LORANGER and BENJAMIN G. LORANGER, citizens of the United States, residing at Detroit, county of lVayne, State of Michigan, have invented certain new and useful Improvements in Patients Adjustable Tables, and declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to tables for supporting a patient undergoing chiropractic or similar treatment. This treatment consists in the adjustment of the vertebrae of the spinal column and in order that this adjustment may be conveniently secured, it is necessary that the patients abdomen and back be free from support. Inasmuch as patients are of varying height or proportions, a table that would be adapted for one would not be suitable for another. Sliding tables have been used wherein the portion that is used to support the chest of the patient has been slidable with respect to the portion that has been used to support the legs. This, however, has required the disturbance of the patient which is painful in case of an aggravated condition.

It is the object of this invention to provide a table in which these adjustments can be made without in any way disturbing the patient and yet just the amount of support can be obtained that is desired by the operator.

In the drawings :-Figure l, is a perspec tive of the table. Fig. 2 is a longitudinal vertical section. Fig. 3, is a cross section on the line 3-3 of Fig. 2.

The table comprises essentially three sections, the leg supporting section A, the body supporting section B and the head supporting section C. The leg supporting section A comprises a suitable cushion which is supported upon legs 1. The head supporting section C comprises a suitable cushion which is supported on legs 2. These are connected by the runners 3. The body supporting section B comprises a cushion that is fastened to the head supporting section C by a clamping bar 4 and which is contacted upon its under side by a plurality of cross slots 5 fastened to a canvas strip 5.

Specification of Letters Patent.

Application filed March 21, 1913.

Patented Aug. 26,1913. Serial No. 755,896.

The end of the strip of slats 5 opposite the end clamped to the head supporting section is clamped to a slid-e 6 by means of a clamping bar 7. The slide 6 comprises a pair of rods 8 that slide through bearings 9 under the top of the head-supporting section C. These sliding rods 8 are connected at either end by cross bars 10 and in the center is a sliding rack bar 11 which is T-shaped in cross section and slides through a T groove in the bearings 9.

The cross bars 12 connect the posts 20f the head supporting portion and in these is ournaled a crank shaft 13 which carries a pinion 14 that meshes with the rack bar 11.

On the end of the crank shaft 18 is a crank and handle 15 by which the crank may be turned. It will readily be understood that by turning the crank the rack bar is pulled one way or the other, depending upon the direction of revolution of the crank shaft. This pulls the slide in or thrusts it out and the slide carries the slat strip 5 of the body supporting portion. When the patient is put upon the table, as shown in Fig. 2, the body supporting portion is in contact with too large a portion of his abdomen, but by turning the crank, the slide may be forced out and the slat-strip 5 partly rolled up. The cushions take the position shown in the dotted lines of that figure and drop down upon the springs 16 that stretch from bar 17 of the leg-supporting section to bar 18 of the head-supporting section. This adjustment may be made without disturbing the patient in the least. Or, in case it is found that the abdomen of the patient needs more support than is given it by the position of adjustment of the table, the crank handle may be revolved in the opposite di rection to bring more of the cushion in contact with the body of the patient. To hold these adjustments, we have provided a disk 19 which has notches in its face into which may be thrust the end of a hand-screw 20 that is threaded through the cross bar 12. This serves to hold the slide at any given position of adjustment and the slide may be readily released by a simple turn of this hand screw when it is desired to readjust the table.

Vhat we claim is 1. A table for supporting a patient undergoing treatment, having in combination, a leg-suporting section, a head-supporting section and a body-supporting section comprising" a flexible supporting member tened to one of the first mentioned sections, and a slide reciprocablc through that section and fastened to the opposite end of the flexible supporting member, substantially as described.

2. A table for supporting a patient un dergoing treatment, having in combination, a leg-supporting section, a head-supporting section and a body-supporting section, comprising a cushion fastened at one end to one of the two first mentioned sections, a flexible slabstrip for supporting the cushions and a slide reciprocable through the section to which the cushion is attached and fastened to the slab strip, substantially as described.

3. A table for supporting a patient un dergoing treatment, having in combination, a leg-supporting section, a head-supporting section and a body-supporting section. supported by one of the first two mentioned sections and comprising a flexible supporting member attached to said section, a slide siunported slidingly by said section and attached to the end of the flexible supporting member, the said slide being provided with a rack bar, a pinion in mesh with the rack bar and a crank shaft and crank for rotating the pinion to move the slide for the purpose of bringing more or less of the body-supporting section with the body of the patient, substantially as described.

i. A table for supporting a patient undergoing a treatment, having in combination, a leg-supporting section, a head-supporting section, a body-supporting section s'u 'morted by one of the two first mentioned sections and comprising a flexible support- 40 ing member attached to that section, a slide slidably supported in such section and attachcd to the opposite end of the flexible supporting member, said slide being provided with a rack bar, a pinion engaging with the rack bar, a crank shaft upon which the pinion is mounted, a crank handle attached to the crank shaft for the revolving of the same and means for holding the crank shaft in any position of revolution so as to maintain the adjustment secured by turning the crank to move the slide, substantially as described.

5. A table for supporting a patient. un- (lei-going treatment, having in combination, a leg-supporting section, a head-supporting section, a body-supporting section interposed between the first two mentioned sections and somewhat spaced from one of the sections, the said body-supporting section being provided with an adjustable supporting surface comprising a flexible member capable of being rolled out or rolled in, whereby it zuoproaches or withdraws from the section from which the body-supporting section is spaced and means by which the said flexible member is rolled out or in, whereby more or less of the bOCly-SUPPOl'ting member may be brought into contact with the body of the patient and maintained in such position, substantially as described.

In testimony whereof, we sign this specification in the presence of two witnesses.
