,0 the art to which it appert-ams to make and use the same.

My invention relates to new and useful improvements in surgical chairs and more particularly to that class adapted to be used ,5 for the correction of spinal curvature and my object is to provide means for engaging the head and neck of the patient for directing an upward pull thereon.

A. further obgect is to provide. means for :0 anchoring the end of the cable employed for operating the head stall.

' A further object is to provide adjustable means for engaging the shoulders and arms of the patient. g

: A furtherolgjec't is to provide a revolving seat for thechair and mounting the same on roller bearings.

A further object-is to provide means for holdi the seat in its adjusted position.

:0 3 A still further object is to provide a band forproperly-securing the patlent in the seat.

A further object is to provide means for adjusting said band to accommodate larger or smaller zlpa-tients and a still further object :5 is to provide'n'ieans for adgusting the standard employed for holding the head stall.

Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claims. to In the accompanying drawings forming part of this application, Figure 1 is a perspectiveview of thechair complete. Fig. 2 is a central vertical sectional view through the chair, and Fig. 3is a horizontal sectional L5 view through the chair at a point above the ,seat I Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 1

' 0 indicates the frame of the chair which may be constructed in theusual or any preferred manner, the rear post of the frame being provided with a back 2, while forwardly of said back is a platform 3 and extending up- 5 wardly fi am the platform are arm rests 4, although t will be clearly understood that these parts may be constructed tobest suit the occasion.

Mounted upon the platform 3 is a seat proper 5, which is held in position on the platform by introducinga bolt. (3 through the seatand platformand in order to permit said seat to readily rotate, curved plates 7 and 8 are embedded in the platform 3 and seat 5, respectively, said plates forming a race for bearing balls 9, the diameter of said balls being such as to space the scat a distance from the platform, so that the pa tient may readily rotate the seat to change the position of the body.

In order to hold the seat in its adjusted Patented Mar. 8, 1910.

position, a strap 10 is fixed at its longitudinal center tothe rear edge of the seat, the ends of the strap extending forwardly and into engagement with any suitable form of spring clamps 11,.whicl1 clamps serve to hold the ends of the strap a ainst. longitudinal movement when the strap is securely engaged with the clamps and it will be readlly seen that by releasing. theclamps, the seat may ,be rotated tOll1( pI'0])Gt position when the clamps. are again engaged with the strap and as the clamps are positioned 111 convenient reach of the patient, the adjustment of the seat can be readily accomplished by the patient. The seat 5 is providetlav'itli a covering 12,

of any suitable material, preferably leather and to said coverin is attached a .Jlllld. 13,

also preferably of leather, said band having its lower edge attached to the covering by means of a lace 14 or otherwise and \by providing that portion of the covering ad- ]acent the side edges of the seat with series of openings 15 to receive the lace, said band may be adjusted to fit around patients oft.

various sizes and in ordenjo securely clamp the band around the hips of the patient, the upper forward edges ofthe band are provided with tongues 16 to one of which is attached abuckle 17 and to the other a positioning the band around the patient and extending the strap 18 through the buckle 17 and drawing the same taut, the patient .will besecurely strapped to the seat.

The back 2 is provided with

slots

19 and 20, which slots are arranged in pairs and on opposite sides of the vertical center of said back, said slots being preferably ar-' ranged at an angle to the vertical center of the'back and each parallel with each e the inner ends of-the bolts are attached

shoulder straps

24 and 25, respectively, said and over the I the chair.

upper portion of the straps bein adapted to extend around the shoulders 01 the atient and form a support at this point and in view of the length ofthe slots through said straps maybe adjusted to accommodate patients varying in height,

Adjustably attached to the rear of the back 2 and-preferabl at the vertical center thereof is a standar 26, said standard being provided with vertically extending slots 27, through which extend bolts 28 and by means of which the standard is held in engagement with the back, the outer ends of the bolts being threaded to receive w'ng' v nuts 29, which bind ag ainst the stand rd and. hold the same in itsyertical adjusted position.

At the upper end of the standard 20 is an inwardly 'jects forwardly over-the back of the c air In order to su ort the head of the tient, a head stall which is adapted to fit aroundvand over the head,-one part of'the stall having'achin strap 32, which isadapted to extend below the chin of the patient and in the rear of the chin strap is a neck strap33, which is adapted to extend in the rear of the "head adjacent the neck of the patient and in order to operate the head stall, a cable 34 is attached to the upper portion of the stall and extended upwardly through anopenin 35 in the .free end of.

the section 30, said cable thence extending over sheaves-36 and 37 "on the section 30,

thence downwardly and around a sheave 38 attached to the lower end of the back 2, from whence said cable extends over the platform 3 to a point adjacent the forward at one edge thereof, the free endof said cablebe'ingse cured by a spring clamp 39 and as said clamp is positioned adjacent one of the,

I clamps 11, it

will be in convenient reach of thepati'ent when occu ying the chair.

-By arranging the (l 6VlC8 as herein disclosed, it Will be readily seen that the W1- rious parts thereof may be adjusted by the patient while occupying the chair and if the patient finds that one position becomes which the bolts ext end,

tientwishes to change the position of the head by raising or lowering the same, the free end of the cable 34 may be released from its respective spring clamp 39 and the 'be readily rotated to adjust thesame and that the band ad'usted to accommodate different patients.

it will also be seen that thepatients, unless entirely helpless, can adjust the various parts of t e device without requiring the assistance of an attendant and in view of the simplicity of the chair, it can be very cheaply constructed and at the same time rendered strong and durable.
