SURGICAL BAKER.

Application filed March 15, 1322. Serial No. 543,826.

To all iv/loin it may concern.

le it known tl- Piziunmt'i. a

residing at ivania. h:

elphia. and ted new ul improve i iiiw'ieal linkers. A the tollo. a full, clear. and exact description. red rence l: -ing' had to the accompanying drawings. which form e. of bis specification.

lily invention relates to an improvement in surgical bakers of the type used in the application of heat. derived from elec ric lamps, to the limbs or other part of the body in the treatment of rheumatism. etc.

Heretoliore the bakers oi the type to which my invention applies have been diilicult to properly apply to the patient because of the diliculty in properly supporting them in place and because of lack of adjustability. Thus a cmisiderable variety of sizes have been required. Further. the bakers heretofore have been so cumbersome as to flllkt their transportation from place to place highly inconvenient.

The object of my invention is to provide a halter which will be self-supporting and completely adjustable and which may be applied readily to the patient to be treated.

A further object (it my iuvei'ition is to provide a baker which may be readily eom paeted for transportation and the transportation of which may be readily acconnilished by hand.

Further, to proride means for retaining the baker in operative adjustment or coirpacted which will be highly efficient and insure the permanency of any adjustn'ient until a change is desired.

Having; now indicated in a general way the nature, purpose and advanta 5 of my invention. T will proceed to describe a preferred embodiment thereof. in detail. with reference to the accompanyiug drawings. in whichl a longitudinal sectional view of a baker embodying my invention. partly broken away Fig. 2 is an end view 01 the ubject of Figure l compacted tor transpr)rtation.

Fig. 3 is an end view oil the auirieet oi' Figure l adjusted to operative position.

Fi 4- is a view (it a detail of the construction of the subject of Figure l.

Pi s. 5 and (i are views of the members :lormn connection between the bot of the baker and its support The body of the baker comprises two similar arcuate members a. a, each being longitudinally braced by means or metal rods 7). which extend between the end pieces c covered with fibre. The end pieces serve to support. on their inner faces, a series o lamps and lamp sockets c, suitably connecteo by means otwires 7', adapted to be connected to a source (it current. through a switch, not shown. which may be oi such a nature as to throw all or a. part of the lights on.

At the top of the baker, the end pieces (.1 of the body men'ibers a. a, are adapted to overlap and are pivotally held together by means of threaded pins 9 which pass through the overlapped portions. The pins extend from serrated or toothed bases 72. which in turn are threaded on the end of a rod which extends between the end pieces. The serrated bases 2 are adapted to be drawn against the inside of the end pieces 0 by means of wing nuts 7' threaded on the pins 0.

Thus it will be seen that the body members a, a are pivotally secured together and may be turned together or separately about the pivotal connection by merely loosening the wing nuts j. while when the wing nuts are tightened the serrated faces oi the bases 71 bite into the inner faces of the end pieces 0 and positively prevent any turning of the body members on their pivot.

The rod i passes through the end members of an inverted U-shaped member it, which is supported at intervals by means of additional U-shaped members Z, through the end members of Which passes the rod 2', and to which is secured a handle on for carrying the baker.

At the lower ends of the end pieces 0 are fixed brackets, upon the free ends of which are serrated or toothed clamp members 1i, adapted to be engaged by serrated clamp members 0 from which extend bolts 7) adapt-ed to pass through members m and receive wing nuts g. The members 0, similar to the members 71-, are bored at right angles to the extension of the bolts 7) for the reception of the free ends of U-shaped frames 0* while thumb screws 8 are threaded into the members 0 at right angles to the direction of extension of the free ends of nection. Further, that the body of the baker or either one of its component arcuate sectionsca, a, may be raised or lowered in a vertical direction. Further, one end of the baker may be adjusted above or below the other and due to the flexibility of the frame members 7" the stand may obtain the proper adjustment of the body Without being warped ortWisted out of shape.

it Will also be observed that Where adjustment is desired it may be readily made and Where any adjustment is fixed due to the nature of the holding devices the adjustment will be positively maintained Without any tendency to slippage; at the same time no restriction is imposed on the position into which adjustment may bemade.

Further, by virtue of my invention, it will be noted that, as shown in Figure 2, the baker-and stand may be folded or compacted into a relatively small space for transportation, and in folded position all the delicate parts, as the lamps, etc., Will be thoroughly protected.

Having noW fully described my invention,

a bracket secured to the free end of each of the end members, each bracket having a serrated face, a clamp member tor each bracket having a serrated tace tor engaging the serrated face of the bracket, a clamping screw for clamping the clamp member to its bracket and about the axis of which the clamp member is adapted to be adjusted, each of said clamp members being provided with a bore, the axis of which extends at right angles to the axis of the clamping screw, a pair of U-shaped support members, the ends 01 which are resilient and are adapted to pass through the bores in said clamping members respectively, and means to secure said supports to said clamping members.

In testimony of which invention, 1 have hereunto set my hand, at Philadelphia, Pa, on this 30th day of January, 1922.
