TELL J. BERGGREN, 0F BATTLE GREEK, MICHIGAN.

OSTEOPATHIC-TREATMENT CHAIR.

To all whom it may concern:

Be it known that I, TELL J. BERGGREN, a subject of the Kingdom of Sweden, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Osteopathic-Treatment Chairs, of which the following is a specification.

This invention relates to treatment chairs especially adapted for osteopathic practice, and has for its object, improvements in that class of apparatus which can be adjusted in different positions for the treatment of the varying conditions of patients. For this purpose I contemplate, in combination with an adjustable-back reclining chair, a suitable foot and leg-engaging holder arranged at the forward portion thereof whereby the subject undergoing treatment may, in the event of reclining in an extreme backward position, catch the feet and be prevented from careening or falling from the chair. I also contemplate, in combination with a chair of the class described, providing at either forward lower side thereof a stirrup for the purpose of engaging the feet, whereby a subject undergoing certain backward or side inclinations will be held to the chair while thus undergoing treatment. There are also other improvements in the details which will be pointed out in the specification and claims.

In the drawings forming a part of this specification, Figure 1 shows a side view of the chair, the dotted lines illustrating some of the various positions to which the back and the leg-holding bracket may be adjusted. Fig. 2 is a plan View of the chair. Fig. 3 is a rear view. Figs. 4 and 5 are detail sectional views of the leg-holding bracket link adjustment, Fig. 4 being a cross section of Fig. 5 on the line m.r. Fig. (3 is a side view of the chair with a modified form of leg-holding device Fig. 7 is a broken plan view.

In the drawings, like marks of reference refer to corresponding parts throughout the different views, in which A, represents the chair seat, B, the adjustable reclining back, and O, the adjustable leg-holding bracket.

The chair seat may be supported in any ordinary and convenient manner, and as illustrated is mounted 011 the four legs, 1, arranged in nearly equilateral positions to the chair seat, as shown. Connecting the Specification of Letters Patent.

Application filed January 3, 1910. Serial No. 535,946.

Patented May 21, 1912.

legs on either side thereof and near the lower extremities thereof, rungs or connecting braces, 2, are provided, and to each of these rungs. and near the front legs of the chair, foot-stirrups, 3, are attached.

To the seat of the chair at the rear thereof, the back, B, is hinged on pintles, 4, and to the sides of the back standards, quadrants, 5, are attached. These quadrants are adjustably secured in the various positions to which they are adapted to be placed, by means of a headed and screw-threaded clamping rod, 6, and correspondinglythreaded hand wheel, 7, run onto the threaded end of the rod in the ordinary manner, the rod in the present instance passing through the rear legs of the chair and through slots 8 within the respective quadrants, as shown. This quadrant, by preference, is marked with the degrees of a circle and is intended, in connection with the adjustment to which the back, B, may be placed, to afford a means whereby any special degree of attitude may be given a patient or subject undergoing treatment while in the chair. It also affords a means for regulating the angular adjustment of the chair back from day to day by degrees or fractions thereof, as may be deemed expedient in the treatment of a patient, and by keeping data of the preceding day on which a patient has undergone treatment, the adjustment may be regulated to suit the occasion, either up or down on the quadrant.

To the forward portion of the chair, a leg or foot-holding bracket, 0, is attached. By preference this bracket is T shaped, as shown in Figs. 2 and 7, the top or crosshead, 9 bein situated above and forward of the chair seat and in parallel arrangement with the forward edge thereof. This head piece. is attached to the upper ends of the staiulards, 10, which in turn are pivotally attached and capable of backward and forward movement, with respect to the chair, on a cross-bar 11 connecting the front legs of a chair, as shown. Near the upper portion of the bracket and hinged below the cross-head 9, an adjustin llnk 12 is provided. The free end of th1s link extends below the forward central portion of the chair seat, and is received through eyelets 13 formed on a bracket 14 attached to the undersides of the chair. Between the aforesaid eyelets and about the free end of said link, an eyelet 15 formed on a clamping rod 16, is

fitted. The free end of this clamping rod is screw-threaded and passes through the side of the chair seat and is fitted with a correspondingly screw-threaded hand wheel or nut 17, by which means the link may be secured in various adjustments necessary and expedient for regulating the pitch of the leg or foot-holding bracket.

In lieu of the pivotally-hinged leg-holding bracket before described, I have shown, in Figs. 6 and 7, a leg or foot-holding bracket, C, capable of backward and forward adjustment with respect to the chair, in a modified form. In this instance the cross-head 9 is attached to the upper curved extremities of the longitudinally-adjustable slotted sliding members 18, which pass between the front legs of the chair over thecross supports 19 below the chair seat, and to the outer sides of the parallel seat sup ports, 20. That the leg-holder may be secured in the various positions to which it may be expedient that it be adjusted, a headed clamping bolt 21 passes through the supports 20 through slots 22, in the members 18, and a threaded end thereof extends through the side of the chair seat and is fitted with a correspondingly-threaded hand wheel 23, by which means the slotted members 18 may be clamped in their adjustment to the supports 20.

In operation, the subject requiring treatment for certain ailments of the leg, back and abdominal muscles, and for correcting certain spinal afl'ections, lies upon the back with the feet engaged below the T-head of the leg-holding bracket, 0; in this position, the

- adjustable back,B,of the chair, maybe regulated to suit the occasion, the degree of angularity may be either up or down and in either case the degree of position may be observed and regulated from day to day as the condition of the patient under treatment may require. With the feet of the patient engaging the leg-holding bracket, the operator may also work the arms, head and neck of the subject in various attitudes without fear of causing the subject to roll or fall from the chair.

lVhen it is expedient that abdominal, back and other muscles should undergo stress of peculiar side or pivotal movements with respect to the hips, or backward movement in connection with the side and pivotal movement, the feet of the subject are placed Within the stirrups 3, which will prevent the subject from losing hold of the chair during treatment.

Various modifications in detail may be re I sorted to without detracting from the essence or departing from the spirit of the in vention.

Having, therefore, set forth the objects and purposes of my invention, what I claim 1s:--

1. In an article of the class described, the combination with a chair, of a leg-securing holder arranged forward of and above the plane of the chair seat, said holder comprising a transverse foot securing head piece having a standard pivoted to the lower forward portion of said chair, as and for the purpose set forth.

2. In an article of the class described, the combination with a chair, of a leg-securing holder arranged forward of and above the plane of the chair seat, said holder comprising a transverse foot securing head piece having a standard plvoted at or near the lower forward portion of said chair and TELL J. BERGGREN.
