Apphcation 'ledJune 14, 1916.' Serial No. 103, 338.

To all whom 'it mcg/il concern-r Beit known that VI, @SGAR HAMMERBTEIN,

a citizen ot the United States, and resident of the borough of Manhattan, city,.c'ounty, and State ot New York, have Vinventedcertain new and useful Improvements in Medical Apparatus, ofi which the following is a Specification.

My inventionrelates to:medical apparatus and has for 'its object to provide a simple and eicient machine whereby various arts of the human body and more particu arly the limbs thereof' may be subjectedto the iniiuence of heat, or to the effects of light rays or both in a comfortable manner and under the direct control of" the patient. My 4improvement 4further contemplates the provision of a simple apparatus 4which may be readily utili'zedin the cure of many ills and which is cheap to manufacture', easy to install and in which the danger of disarrangement and injury to tliepatient is reduced to a minimum. Other objects of my invention will appear iron-rthe-description hereinafter and the features of novelty will be pointed out in the claims.

` In the accompanying drawings which illustrate an example of` my invention, Figure-1 is a longitudinal vertical section of my apparatus; F1g.,2y is a front end view thereof; F'g. ,3* is a plan view partly in section; Fig. 4is a rear end view and Fig. 5 is a cross-section on the line 5--5 ofFig. 1.

As shown in the-drawings the apparatus comprises a supporting frame consisting of areal` end member l10 and a front end, niember 11 located at aidistance from each other and in alinement andeonnected for instance by means o-rods 12 as shownin Fig.l 3, said supporting frame, if desired, being mounted upon casters 13 carried by the two end members 10 andll. The latter at their upper portions 10a and 11a are circular in form and are provided with rollers 14 located at spaced intervals on the circular portions 1()a and 11, which rollers 14 serve to support circular guide or bearingmembers 15 and 16 preferablyl channeled in cross-section soas to be held against any appreciable axial movement relatively to said rollers 14 as shown in Fig. 41'. The bearing; member 15 is secured, in any suitable manner, to the'v closed rear end of a cylindrical drum 17 while the bearing member 16 is -fastened in .any convenientway to the forward open'endofsaid drum which thus extends between "and is .carried by said tearing member-'S15 and 16.

The said drum 17 with this arrangement is therefbrerotatal: lyl supported. upon the supporting frame or rather upon the rollers 14 thereof. To provide for the ready rotation of said drum ary suitable mechanism-may be provided; fofinstance as shown in the illustrated example the bearing member 16 may be formed with or carry sprocket teeth 18 for the accommodation of a sprocket chain 19 or sai chain may simply engage said member 1t frictionally and4 in some cases may be replaced by a simple belt, and in either. case is operatively connected with a sprocket wheel 2O or its equivalent carried for instance by one of the rods12 as illustrated in Figs. `S3 and' 4. In order to facilitate the actuaticn of said sprocket wheel 20 or its equivalent it may be provided witha suitable operating handle 21, it being understood that lwith Yhe described and illustrated arrangement the particular rod 12 carrying said sprocket wheel 20 will. 4be rotatable wholly or in part as desired. When the illustrated const ruction is followed the'front rollers 14 will le suitably shaped to accommodate the sprocket chain 19 or its equivalent and yet firmly support the drum at its front end as sha wn by dotted lines in Fig. 1.

The drum 17 is formed with a plurality of radially ani outwardly4 extending recessed portions 22 preferably located at diametrically opposite points and extending lengthwise of the drum '17, these recessed portions 22 at tleir rear ends being connected by a similar recessed portion 23 extending Vdiametrically across said drum at its rear end. A plurality of walls 24 and 25 are locatedat spaced intervals in said recessed portions 22 and 23 respectively and form chambers 26 and 27 as shown best in Fig. 1,

said walls 24 and 25 serving as supports for electric lamp sockets 28 and 29 which extend through said walls into the chambers 26 and 27 asa so clearly shownin said gure` These sockets 28 and 29 respectively are adapted to receive and support the electric incandescent lamps30, and 31 and are connected by means of wires 32 with contact 'rings 33 suitably insulated and'secured to the rear closed en'd of said drum'17, and describing circles` about the' axis of the drum as a center. The said contact rings 33 are located in suriace engagement with stationary contact members 34l suitably insulated and mounted upon the rear end member 10 of the supporting member, said contact members 34 being connected by wires 35 with a suitable source of electrical energy. In the preferred arrangement a rheostat 36 is included in the electrical circuit for the purpose of regulating and adjusting the same so that any desired degree of resistance may be obtained or said rheostat may be re laced by a simple switch for opening and c osing the electrical circuit, it being understoo that both the rheostat and switch may be included in the construction if desired.

The front end member 11, in the illustrated example, carries a plate 37 which is formed with a' recess 38 of approximately semicircular shape and with a communlcating opening 39 extending therefrom to the upper periphery of said plate and interrupts the continuity thereof. This opening 39 is arranged to be closed by a slide 40 vertically movable in upright guides 41 secured to or forming part of the plate 37 as shown in Fig. 2, said slide 40 being formed with a recess 42 adapted to register with the recess 38 and form therewith an axial opening communicating with the interior of the vdrum as also illustrated in Fig. 2. To seal this axial opening about the part of the patient being treated and AWhile the apparatus is in operation, the plate 37 and slide 40 are provided with liexible flaps 43 and 44 which are suitably cut out to closely fit about the part of the patient Without discomfort and which respectively project beyond the peripheries of the recesses 38 and 42 as shown in Fi 2.

In addition to the parts so far descrlbed the apparatus includes a stationary member 45 which is secured to or forms part of the .front end member 11 and extends from the exterior of the device into the drum 17 as shown in Figs. 1 and 2. That portion of said member'45 which is substantially hori- 4zontal and projects into the drum 17 is provided atspaced intervals with rests 46 suitably shaped and padded and arranged to comfortably support for instance a leg, of the patient at the thigh, calf and footas shown by dotted lines in Fig. 1. A suitable handle 47 may be provided for facilitating the actuation of the slide 40.

For descriptive purposes it Will be assumed that the apparatus is being used as a medium for treating the lower leg and foot of a patient. In such cases the slide 40 is firstraised by means of the handle 47 to free the opening 39 after which the patient, who may be seated in front of the machine, places the leg to be treated in position upon the rests 46 and within the drum 17 for i'nstance as shown by dotted lines in Fig. 1. In this condition the leg is comfortably supported with the affected parts Within the drum and the patient is comfortably seated in front of the apparatus and within ea reach of the handle 21 and the rheostat 36.

may be otherwise constructed to The slide 40 is now returned .or lowered to normal position so that flaps 43 and 44 surround the leg and hug the same without discomfort to the patient, thus closingthe axial opening of the drum and sealing same as will be readily apparent. The rheostat 36 is now actuated to close the electrical circuit and to produce the desired degree of resistance whereby the degree of heat generated by the lamps 30 and 31 is controlled and regulated to meet the requirements of each specific case and the handle 21 is rotated by the patient. This brings about a rotation of the drum 17 upon the rollers 14 and moves the lamps 30 in circular paths about the patients leg which is stationary and at the same opposite the sole of the patients foot as will be apparent from an inspection of Fig. 1. The operation and use of the apparatus is continued as long as necessary or desired in each instance. It will be seen that the lamps 30 and 31 heat the interior of the drum so that all portions of the leg within said drum are subjected to the effects of the elements 30 and 31 which may always be of a natureto exert a benelicial effect in the cure of many ailments. Owing to the fact that the drum 17 may be constantly or intermittently rotated during the continuation of the treatment, the heat generated by the lamps 30 and 31 is not specificall directed against any one art of the leg ut is diffused and creates a cated zone which is even throughout and which evenly reaches all parts of the leg positioned within the drum and whereby the heat is caused to'penetrate all parts of the aifected leg in a manner easily borne by the patient Without discomfort. During the rotation of the drum 17 the contact rings 33 travel along the contact members 34 and thus maintain the continuity of the electrical circuit whereby the lamps.30 and 31 are ener `zed.

If desired the bulbs o the lamps 30 and 31 may be of colored glass or said lamps produce light rays having special eharacterlstics as to color or effect so that the leg in addition to being baked and heated may be subjected to the effects of such colored or other special light rays, which by the rotation of the drum are also diffused and consequently are not concentrated upon any particular part or parts of the leg under treatment. In Some cases the apparatus may be used entirely as a medium for applying specific light rays to the affected part or parts and may be so arranged that the degree of heat enerated bythe light producing media w1ll be negligible.

Owing to the fact that the apparatus is capable of being operated by and under the directv control lof the patient himself, or b an assistant under his direction, the applin treated.

cation of the treatment may be continued, adjusted and varied at will to produce the most beneficial results and to prevent the same from having any unintended injurious parts being effect upon the particular At the completion of yeach treatment or application the slide 40 is again raised to permit the leg to be easily withdrawn from the drum andthe rheostat 36 is actuated to break the electrical circuit.

`The :.upparatus is simple in construction, easily o])erated, cheap to manllfacture and is not likely to become readily disz'nranged. lt Wilhoit' course, be understood if the ap- ]runtus is to be used solely for the application of heat that other heat generating devices may be substituted for the incandescent electric lights if desired.

Various changes in the specific form shown and described may be made within the scope `of the claims without departing from the spirit of my invention.v
