NEW JERSEY, ASSIGNOR TO THE KNY- OF NEW YORK, N. Y., A CORPORATION OF THERAIY AND INFRA-RED-RAY LAMP.

Application filed. June 26,

This invention relates to a therapy and infra-red ray lamp and the novelty consists in the adaptation and arrangement of parts as will be more fully hereinafter pointed out.

Light and heat have both been used for therapeutic purposes with increasing success during the past few years so that a more exact practice has been gradually evolved demanding more perfect apparatus. Many combinations of light and heat have been developed but these are adapted primarily for surface treatment and are not adapted to penetrate deeply for treatment of deep seated physical troubles. Where it is attempted to so use them it is necessary to make a long exposure for deep penetration and the short heat waves impinge on the skin or surface tissue and are often very irritating because of the long exposure which is necessary in order to secure depth of penetration.

My device is adapted to solve this difliculty and does so in a thoroughly eflicient manner being equipped only with heat elements which throw off at a substantially low temperature long heat waves which are infrared rays and which are readily absorbed by the tissue to the depths required without causing any irritation.

The use of infra-red rays produces a very definite and prompt hyperemia to the parts exposed and such cases as neuritis, myositis, muscular rheumatism, neuralgia, lumbago and sciatica have been treated with good results.

Referring to the drawings Figure 1 is a perspective of my complete device, a portion being broken away to show the internal construction of the stand; Figure 2 is a plan view of the interior of the lamp; Figure 3 is a circuit showing the heating elements connected up in parallel; Figure 4 is a vertical section of the lamp as shown in Figure 1; Figure 5 is a detail of the joint and locking means for the lamp; Figure 6 is a detail of one of the heating elements.

In the drawings 10 is a stand having a base 11 mounted on the usual castors 12. A collar 13 is mounted over the stand 10 so as to slide up and down readily thereon and has a set screw and handle 14 of usual construction adapted to lock said collar 13 in any desired position on said stand 10. A horizontal arm 15 is rigidly mounted in said collar 13 and which terminates at its outer end in a circular hinged member 16 and a split hinged 1926. Serial No 118,682.

member 17 is pivoted on said hinged member 16 by means of the usual bolt and nut 18 and an arcuate slot 19 is cut in the circular hinged member 16 and a third bolt member 20 is rigidly secured in the split hinged member 17 by means of a screw 21 against rotation and said bolt 20 has a threaded portion 22 on which is mounted a flexible washer member 23, a spacer 24 and an outer handle member 25 which is adapted to engage the threaded portion 22 of bolt 20 at 26.

The outer portion of the split hinged member 17 is rigidly connected to a shaft 27 which has at its outer end a pair of clamping members 28 secured together by means of screws 29 in the usual manner adapted to receive and secure rigidly in position the outer shell 30 of the lamp which has ventilating elements 31 at suitable intervals and the inner or deflecting portion 32 of said lamp is secured to the outer shell 30 by means of fasteners This construction of the hinges 16 and 17 permits the lamp to be swung up and down as the handle 25-is loosened on the threaded portion 22 of the bolt 20 thereby releasing the spacer 24 and washer 23 so that the split hinged member 17 may move freely up and down on the pivot 18 on the hinged member 16, the bolt 20 passing freely through the are 19.

The lamp is also connected through wires 34 to a source of power not shown, passing through insulator connector 35 to the space 36 between the inner and outer shells 32 and 30 being connected up in parallel to the sockets 37 as shown in the diagrammatic circuit in Figure 3. Heating elements 38 are mounted in the sockets 37 by means of the usual threaded connector 39 and these heating elements 38 are of usual and well known construction and the circuits through these elements are shown by the series of pointers in Figure 6 and these heating elements 38 are mounted in a horizontal position as indicated in Figure 4 instead of in the usual vertical position. The heating elements 38 are also of such construction as to be adapted to give off long heat waves at a temperature around 900 to 1000 F. being of such construction that they will not readily break nor give off heated particles. For purposes of safety a screen 40 is mounted in the open front of said plant to catch any particles which through accident or any imperfection might possibly fall from the heating elements 38. The inner shell 32 of the lamp has a pyramidal sha ed deflecting element 41 which catches the eat waves comin from the heating elements 38 and throws them in the direction indicated by the two arrows upwardly from the lamp so as to prevent any pocketlng of the heat at this point which would otherwise occur and insuring a continuous movement of the long heat waves travellingfrom the heating elements 38. The space 36 between the inner shell 32 and outer shell 30 also insure the coolness and continuous low temperature of the outer shell 30 of the lamp no matter for how long a period the lamp may he in continuous use. The lamp also has a handle 42 rigidly secured to the outer shell 30 for convenience in handling the same. The even spacing of the elements 38 combined with the deflecting element 41 insures an even distribution of the heat at all times.

A cord 43 is secured-to the collar 13 and passes over a pulley 44 rigidly secured to the head of the stand 10 and a counter weight 45 of usual construction is attached to the other end of the cord 43 whereby the collar 13 and the arm 15 and lamp carried thereon are held in a counter balanced position on the stand- 10 the weight 45 travelling up and down inside of said stand 10 in the usual manner.

It is obvious that many variations may be made in the particular details of construction of this device without departing from the spirit and intent of the invention.

I claim: I

1. In an infra-red ray lamp the combination of electrical heat elements maintaining a low temperature, a pyramidal deflecting means and an arcuated reflector adapted to dilfuse the largest possible amount of long heat waves in a uniform manner.

2. In an electrical lamp the combination of low temperature heating elements mounted a central pyramidal element and an arcuate reflector adapted to diffuse the largest possible amount of long heat waves and means for securing said lampin any desired position in a vertical plane and a horizontal lane.

4. In an electrical-lamp the com ination of low temperature heating elements mounted horizontally in a two spaced shell reflector and a pyramidal deflecting element on the middle of the inside of said inner element and means for securing said lamp in any desired position.

5. In an infra-red ray lamp the combination of electrical heat elements maintaining a low temperature, a deflecting means having a central pyramidal element adapted to diffuse the largest possible amount of long heat waves all mounted on a movable stand, means for turning said lamp to any desired position and means for looking it in said position comprising a set screw on the stand and a compression locking member having a flexible washer on the arm supporting the lamp.

6. In an electrical lamp the combination of low temperature heating elements mounted horizontally in a two spaced shell reflector on a movable stand, a pyramidal deflecting element on the middle of the inside of said inner element, means for turning said lamp to any desired position, means for looking it in said position comprising a set screwon the stand and a compression locking member having a flexible washer mounted in an arc on the arm supporting the lamp.

In testimony whereof I aifix my signature.
