CHIROPRACTIC OPERATING-TABLE.

11 Specification of Letters Patent.

Application filed May- 8, 1917.

I To all whom it may concern Be it known that I, WILLIAM GRANT WILLIAMs, a citizen of the United States, residing at Columbus Junction, in the county of Louise and State of Iowa, have invented certain new and useful Improvements in Chiropractic Operating-Tables; and I hereby declare that the following is a full, clear, and exact description thereof, reference be ing had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement i"n adjustable tables of the general class used by physicians and surgeons and has particular reference to a table for use by chiropractics when operating on patients.

The object of the invention is to provide a novel table which. will be comfortable to the patient and can be readily adjusted to support the patient in various positions while being operated upon.

I will describe one practical embodiment of the invention as illustrated in the accompanying drawings to enable others skilled in the art to manufacture the same, but do not consider the invention restricted to the specific construction and form of parts illustrated, and have set forth in the claims the essential features of the invention for which protection is desired.

In said drawings:

F'gure 1 is a side elevation of the complete table showing the parts in practically normal position, and indicating in dotted lines some of the extreme positions to which the several cushions may be adjusted. Fig. 2 is a topplan view of the table.

Fig. 3 is a plan view of the table with the cushiens, and some of the parts connected theneavith, removed.

Figs. land 5 are detail vertical transverse sections of the table.

Fig. 6 is a detail. V

Referringto the drawings A, B, C and l) represent the adjustable top members or sections of the table, which sections are supported as hereinafter described, and independently adjustable. These sect1ons, are preferably upholstered or cushioned, in any suitable way, to increase the comfort of the patient resting thereon.

As shown in said drawings the table comprises end frames 1 which are preferably connected by side bars or rods 1; the frame June it,

Serial No. 167,2?53.

1 may be cast and the side rods 1 be formed of metal pipes or rods, and have their ends secured in sockets in the frames 1 .in any suitable way.

Mounted upon the side rods-l adjacent one end of the main frame is a support 2,

hich may he a casting, having sleeves 52 slidably engaging the bars 1 and sustaining the support vertically thereon while allowing it to be adjusted longitudinally thereof. The support may be secured in position on the rods, when adjusted, by any suitable means, as by tap bolts 2 engaging the sleeves 2".

Pivotally mounted upon the support 2'is a member S, which may be cast, and upon which the top section D may be supported. This member 3 1s hinged on the support 2 so it can tilt longitudinally of the main frame. As shown it is provided with depending lu gs 3 which are transfixed by a rod 3 the" ends of which are secured in openings in the upper end of the side members of the supports 2, see Fig. 5.

The member 3 is provided with a segment 3 whichis approximately semi-circular and disposed in the longitudinal plane of the mainframe. ,-'Tl1is segment is provided on its under side with notches 3 wnich are adapted to be engaged by a bolt at confined in a recess 2 in the lower side of the sup w port 2, see Fig. 5. The bolt 4 is normally pressed upward by means of a spring 4 confined in the recess 2 and interposed bevtween'the lower end of this recess and a pin 4 on bolt When bolt iis disengaged from the seg- 11181113 the member 3 and top section D thereon can be tilted longitudinally of the frame to any desired angle intermediate the two extreme, angles indicated in dotted lines in Fig. 1; and when adjusted to the desired position can be held in such position by re engaging the bolt t with the related notch 3 in the segment. The segment may be provided with-limit stops or lugs 3 to prevent its being rocked too far in either direction.

The-member 3 is provided at its sides with perforated studs 3 through which pass guide rods 5 which are connected at their ends to brackets fastened to the ends of the section D.

The top section D is thus attached to but till Elli) adjustable longitudinally of end upon support 3; end it Indy belnstencd in env delower end of bolt l, end sand lever extends transversely of the table to and beneath both the sleeves 2, beyond which it projects, end is provided on its outer ends with hand or pedal pieces P by which. eitl'ier end of the lever can be depressed. When one end is depressed its other end acts as e fulcrum. The ends of the lever 4i they be. slotted and guided on thebolts 2 attached to the sleeves 2; and helical expansion springs al may be strung on these bolts between their lower ends and the lever l", on solid springs tending'to return the lever l to normed position after it is depressed.

Slidably mounted on the side hers 1 ed jecent the other end oi": the main frame is a,

second support (3, in general similar to the fill support 2, and having sleeves 6 engaging the side hens 1*. Mounted in the upper end of the support 6 is it her or rod 6 on which are hinged the supports of the top sections A, B and C i As shown the section A is attached to it member 7, see Fig. 3, which member may be cast and has perforated lugs 7 on its inner end transfixed by the shaft 6 to hinge the member 7 end section A thereon. From the under side of this member 7 depends a,

segment 7 which is provided on its under side with a. series of. notches. 7 any one of which may be engaged with a bolt 8 mpunted in e' chamber 6 in supporth similrir to the bolt 4: in support 2.

The holt 8 may he upheld by e spring 8', and may he pivotelly connected. at bottom to a lever 8 which is provided with hand or foot pieces 8 at its outer ends, and "which to sleeves 6, and upheld by springs 8 on said bolts, substantially as lever t is supported and upheld. it either end of lever 8? is depressed the'oolt 8 Will he disengeged from segment 7; end then the member '2 and the top section A attached thereto can be ad justed to any desired position intermediate the two extreme positions indicated in dotted lines in Fig. l.

As shown the top section C is mounted on bars 9 which are hinged on rod h. The section 0 being suitably attached to these rods but suliicicntly removed from the section A to cnaiole section B to be located between the sections A end C.

The free ends of the hinged hers 9 supporting; section C msy he connected, it desired, by a rigid memher l? 3) from may he guided by means of holts ii attached 8 as shown.

By turning the screw the nut ii err adjusted to or from the pivot ll oif tl" ver it, end thus uphold the outer end seid lever, which is eiigeged with le with greater or less pressure, provided the bolt 12 is disengaged from the slots in lever 100 "When the bolt 12 engaged with the notch on lever 10, these levers 10 end, ere rigidly connected, and the springs hecoine inefiective. i I

The top section B is shorter then the; sections A and G and is preferably etteehed to hinge straps 15 by which it is on the rod 6 as shown in Figs. %2 end its stated the several tofhle sections do, I" v C and D are upholstered. or. cushioned 1irelerobl'y, The section A is preferably provided with e. centred, longitudinelly die neeaeoe si u. The section it supports the head of .t patient, and it he is lying upon his face the section a can he removed so the patients nose will not be injuredduring treatment. The sction B can be adjusted upwardly with the section C as indicated in dotted lines Fig. l; but when section B is fully lowered, as also indicated in dotted lines in I Fig. i, the section '6 will be supported by the horns tr of the support 6.

The section C is adjustable between the extreme positions indicated in dotted lines in Fig. 1. It is primarily adjusted by I 1. loosening the set screw 10 and ad usting the section C relative to the lever 10, after which it is fastened by setting the screw 10.

If the bolt 12 is in engagement with one of the notches 10 in lever the section 0 would be rigidly supported, but if it is desired to have it yieldingly supported the bolt 12 is disen aged from the lever 10, and held disengagec by partially turning it as described, and then the section C and lever 10 yieldingly supported by the springs 14:, the pressure of such supporting springs being adjustable by turning screw 13 to shift the nut .13 toward or from the pivots 11.

The section I) may be adjusted toward or from the section (3, and arranged at any desired longitudinally of the frame to suit persons of different lengths. The section D preferably has a cut-out portion or recess d in its inner end. This recess is very important, and protects certain parts oi the body of a patient lying in certain positions on the table from injury by contacting with the section while the patient is imdorgoin the treatment that this table is designed or.

- From the foregoing it will be seen that the sections A, C and D are all independently adjustable and can be relatively adjusted to support the body of a patient lying upon the table in any desired position. The section C can be either rigidly or yicldingly supported. according to the treatment to which the patient is to be subjected.

'l he abdominal supporting section C can be locked rigid at level or any angle; and can be lowered out of the way if desired. When in it lowermost position the leg rest section 1) could he moved inward to more or less overlie the section C.

iii

The cushion a can be reversed to have an The section l can be moved backward or forward to accommodate patients of difierentheight, and can be given any dosired. inclination to suit the position it is desired to have that part of the body resting on section it) assume.

The sections 1) and [loan be "aised or lowered together to any desired positions, until section B rests upon the horns t Then the section 0 can he further lowered independently of B. The section (I can be either rigidly sup mrtcd when adjusted by levers 10 and 11, or it can be yicldingly supported by springs 1% and levers l0 and 11; and the tension or sprmgy condition,

desired by the operator, is obtained by turning the handle 13 to shift the nut 13 forward or backward.

lit Will be seen that this table has a wide range of adjustments to suit any position of the patient required in chiropractic operations; and it can he usedby surgeons and physicians as an operating table, or

readily adapted for such uses.
