Specification of Letters Patent.

Patented May 9,1922.

Application filed July 31, 1918. Serial No. 247,849.

To (all whom it may concern:

Be it known that we, JOHN V. MoMANrs and FRANK TTOENIGKRAMER, citizens of the United States, residing, respectively, at Kirksville, county of: Adair, State of Missouri, and at Cincinnati, in the county of Hamilton and State of ()hio, have invented certain new and useful Improvements in Treatment Stools, 01 which the following is a specification.

Our invention relates to improvements in treatment stools. -One of its objects is to provide an improved stool to administer osteopathic and similar treatments. Another object is to provide improved means to support, adjust, and clamp the seat to different positions. Another object is to provide improved means to retain the stool and patient in position relative to the stool supporting means during the treatments, or to enable the operator to maintain definite relations to the patient on the stool. Another object is to provide'adjustable and detachable means to support the back upper portion of a patient relative to either a rlgid or an adjustable seat. Our invention also comprises certain details of form, combination and arrangement, all of which will be fully set forth in the description of the accompanying drawings in which:

Fig. 1 is a side elevation of a stool embodying our improvements.

Fig. 2 is a section taken on line 2 2 of Fig. 1.

Fig. 3 is a plan of the operators foot rest, detached.

F .41 is a sectional detail of F ig. 1.

Fig. 5 is a bottom plan of one of the clamping members, detached.

on line A: 4;

6 is a perspective view of another clamping member, detached.

Fig. 7 is a view similar to Fig. 1 illustrating a modification. I

Fig. 8 is a plan of the several members of the back support of Fig. 7 detached from the stool.

F ig. 9 is a detail illustration of a modified and adjustable back support.

The accompanying drawings illustrate the preferred embodiments of our invention, in Figs. 1 to =6 of which 7 represents a base having preferablya plurality of legs 8 to rest upon the floor, and an upright section 9 provided with a vertical polygonal recess or perforation 10. An adjustable standard 11 of polygonal cross section to register with the perforation 10 serves to adjustably support a seat 12.

In order to firmly clamp the standard 11 relativeto the base against movement endwise or rotatably, we provide a yoke or cap 1 1 to seat upon the upper portion of the base section 9, being held thereto by means of a pin 15, preferably tapered, which through its middle portion engages a pen foration 16 in the base section 9, and at its ends engages perforations 17 and 18 in the cap or yoke member 14. The member 14- may be further secured. to section 9 by a screw19 ii desired. I

The upper portion of the member 9 is cut away. or recessed at one side of the standard 11 to provide space within the cap 141 to receive the movable clamping member OTCjFHV 20, which seats within and is retained in position by the cap 1 1. The

jaw 20 is provided with clamping faces 21 to engage a plurality of faces of the stand-- ard 11 in such manner as to firmly clamp the standard 11 in any desired position to the base member 9. without lost motion or liabilityof vibration or slipping thereof from its adjusted position when subjected to the strain of administering treatment, as serious injury might occur therefrom. The cap member 1 has a threaded recess 22 into which is threaded a clamping bolt 241 to bear against the rear face of the jaw 20 to force and lock the jaw into contact with.the standard 11. The bolt 24 is preferably provided with a hand wheel or a crank arm 25. A sp1ing26 is coiled about the standard 11 between the seat 12 and the top of the cap 14, and is designed to exert suificient lifting force upon the seat to substantially counterbalance the weight of the seat and standard 11 so that when the clamp 20, is released the seat will automatically rise to near the upper limit of its adjustment and come to rest. Thus the lifting power of the spring being coaxial with the standard base section 9, and in adjusting the seat the operator places one hand on the seat and releases the clamp with the other,

" ing the patient in retaining his position upon the seat.

The base section 9 is provided with a rear wardly projecting bracket to which is attached a foot rest member 31 provided with a series of foot rests 32 in pairs at different heights above the floor to serve as foot rests for the operator in different treatments, and for treatment of patients of different dimensions. A metallic mat or standing plate as is rigidly attached to two legs of the base and rests upon the floor in rear of the stool. The plate 34 also under certain circumstances serves substantially in the same manner members 32 as a rest for the feet of the operator.

In the modification Figs. 7, 8 and 9, the parts are as heretofore described, except that the seat 12 instead of being mounted rigidly relative to the standard 11 is adjustably mounted relative to a plate car- 'ried rigidly by the standard 11, by means of ears llcarried by opposite sides of the seat at one end, and ears 42 carried by the plate 40, which ears ll and42 are hinged together by the axle At the opposite end of the seat is a partially squared shaft 44 journaled in ears carried by the plate 4E0 and provided with two eccentrics 4st at opposite ends and a hand operating lever 45. A squared section ofthe shaft i lbears against a leaf spring -10 carried by the plate40 to hold the eccentrics in any adjusted position. Eccentric straps 4:6 engage said eccentrics and are also hinged at 47 to cars 48 carried by the seat 12, whereby the seat may be tilted at its forward edge upwardly or down wardly from the full line position, of Fig. 7. We have also illustrated a detachable and adjustable support for the back or upper portion of a patient, comprising a pad 50, preferably provided with curved ends to engage under the arms of a patient. This pad 50 has a forked shank 51 pivotally' connected by a clamping bolt 52 to a link member 58, which is slotted at 54, and adj-ustably connected by clamping bolts 55 and 55 to a link, section 56 which in turn is pivotally connected by a clamping bolt 57 to the forked arms of a shank 58. The shank 58 is detachably connected to the plate 40 by in serting it under the yokes or loops 59 and 60 and clamping it in place with a setscrew 61.

The bolts 55 and 55 when loosened permit the sections 53 and 56 to slip endwise relative to each other to increase or decrease the distance between the centers 52 and 57 to secure different positions for the pad 50. Adjustment of the pad 50 upon the centers 52 and 57 and adjustment of the seat 12 also provide for securing practically any desired position of the pad and seat relative to each other. In the modification Fig. 9 we have shown a pad support 62 to be adjustably supported upon the bolt 52 in place of the pad 50. The member 62 is provided with two pads 63 and 64: which may be adj usted to and from each other to engage and support patients of different dimensions, the curved ends of said pads 63 and ea being adjustable to fit snugly under the arms of a patient to retain him in the desired position.

A considerable variety of treatments are designed to be employed upon different patients varying considerably in dimensions, which treatments are provided for by adjustment of the seat and back, and different positions of the operator. In some treatments the patient is positioned upon the seat, and may be harnessed thereto, with or without the back supporting pad, and the oper- I ator stands upon the mat 34 to retain the stool in position upon the floor, and the patient in definite relation to the operator,

while the upper portion of the patient is moved by the operator to various positions to secure the desired muscular and joint movements. tient is positioned upon the seat and may be harnessed thereto, while the operator is seated upon a chair or table orv other object in rear of the patient with the feet of the operator upon one or other pair of foot rests 32 and the knees of the operator resting against some portion of the spine or back .of the patient the hands of the operator being employed to grasp the shoulders of the patient to cause such movements as desired on the part of the patient. By moving the feet of the operator from one to another of the several foot rests 32, the knees of the v operator may be brought to bear upon any desired portion of the back of the patient to serve as a support in securing the desired movements. I

The apparatus herein illustrated and described is capable of considerable modification without departing from the principle/of our invention.
