THERAPEUTIC LAMP.

To all whom it may concern.-

Be it known that I,-.RICHARD G. LEDIG, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Therapeutic Lamp, of which the following is a specification.

My invention consists of an electric lamp which is provided with a hood or shade of the form of a parabolic conoid with an interior reflecting surface which serves to project the heat of the lamp from the hood in a high degree for effective therapeutic treatment of the human body where required, while the light of the lamp is etliciently refiected from the hood.

It consists also in providing the device on the side thereof with a handle which admits of the convenient and effective manipulation of the device in directing the heat to the portion of the body to be treated with the same, and the regulation of the heat to a greater or less extent at the place of service.

It consists also of details of construction as will be hereinafter set forth.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may he varied, and so it is to be understood that the invention is not limited to the specific details shown and described.

Figure 1 represents a central longitudinal section of an electric therapeutic and light ing lamp embodying my invention.

Fig. 2 represents a top or plan view thereof on a reduced scale.

Fig. 3 represents a side tionthereof on the scale Fig. 2.

Fig. 4 represents a side elevation of the switch plug and appurtenances thereof.

7 Fig. 5 represents a top plan view thereof.

Fig. 6 represents a transverse section of a portion on the line 6-6 Fig. 3.

Fig. 7 represents a central section of the cap of the lamp socket.

Fig. 8 represents a transverse section on the line 88 Fig. 7.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings,

1 designates an incandescent electric lamp, and 2 designates a hood in which said lamp is sustained and secured by the threaded neck 3 and the threaded sleeve 1 on the switch plug 5, the latter being contained in the lamp socket 6, said sleeve 4 being a mem- Specification of Letters Patent.

ber of said socket, which features of themselves are well known.

The hood is of the form of a. parabolic conoid widening in its curved contour from the neck of said hood to the open end of the same, and has its interior surface 7 of a highly reflecting material or nature, it being noticed that the bulb portion of the lamp 1 is contained entirely in the hood 2, whereby heat from the lamp is reflected to the fullest extent from the hood for therapeutic purposes, the same being true of the light from the lamp for illuminating purposes.

' In the side of the neck of the hood adjacent to the neck of the lamp 1 are the vents 8 which open into the interior of said socket so as to serve as exits for the heated air.

9 designates the electric wire or conductor, the same passing through the handle 10 of the device, the handle being formed of rubber, wood, or other suitable material, it being secured to the side of the socket 6, said conductor having its terminals in the latter divided, the divisions being secured to the binding screws 11 on the plug 5, the portion of the latter adjacent to said screws having therein the recess 12 to have the portion of the conductor 9 seated close thereon, it now being seen that by proper manipulation of the key 13 on the plug 5, the current may be turned on to energize the lamp and cut off from the lamp to extinguish the same, as usual in such cases.

Within the socket is the insulator 14: of tubular form inclosing adjacent members for evident purposes, the same having in its side the opening 15 for the passage therethrough of the adjacent portion of the conductor 9.

l6 designates a cap which is fitted upon the upper end of the socket to close the same, it having on its upper or outer end which is tubular, the shank of a ring or loop 17 by which the device may be hung upon a hook, etc., or suspended from a stand or some other desirable place.

In order to connect the cap tightly with the socket, and vice versa, the upper end of the socket is corrugated or toothed as at 18, and the lower end of the cap has therein a reinforcing piece which has openings 19 at intervals, the corrugations 18 being adapted to enter said depression, thus interlocking the cap with the socket, but admitting-of the disconnection of the same when superior force is applied one to the other. The upper 7 ring in sald portion, as most portion of the socket is split or slotted as in Fig. 3, so as to render the same resllient and cause the cap to contract the same for more tightly holding the cap in position on the socket.

In order to retain the hanger or suspension ring 17 on the cap there is employed the screw 20 which is passed through the side of the top portion of said cap and adapted to tighten against thescrew shank of the plainly shown in Figs. 1 and 7.

Attention is directed to the fact that the device may be most conveniently manipulated and directed to a required spot for therapeutic purposes, or even lighting purposes, by means of the handle 10 which is made hollow to allow the conductor to pass through the same to and unto the socket 6, said handle being adapted to be gripped conveniently and firmly by the hand of the operator.

In order to connect said handle reliably with the socket its inner end is adapted to be screwed into the sleeve 21 through which the conductor passes on its Way into the socket, said sleeve having on its inner end the threaded nipple 22 which is adapted to be screwed into the tubular boss 23 on the side of the socket, thus forming a firm connection of the handle with the socket, and consequently with the hood, said handle being however removable from the socket whereby it may be folded with the exterior portions of the conductor on the hood and form a compact bundle, convenient for packing, storing, transportation, etc., it being noticed that when the handle is removed from the boss 23, it may slip over the conductor 9 without disturbing the latter or dismembering the same, allowing said handle and conductor to be folded on the hood, as above stated.

Having thus described my invention I claim as new and desire to secure by ters Patent, is

1. In an electric therapeutic lamp, a hood, the latter being provided with a socket, a boss extending from said socket, a handle connected with said boss and extending laterally therefrom, said handle and boss being tubular, and a current conductor which is passed through said tubular handle and boss into said socket and connectible with the binding devices of the switch plug of the lamp.

2. In a therapeutic lamp, the combination of a socket, a tubular, interiorly-threaded boss attached to and extending laterally from the socket, a tubular handle exteriorly threaded at its inner end and disposed laterwhat Letally to the socket and in alinement with said boss, a conductor extending through the handle and boss and into the socket, and a sleeve interposed between the handle and the boss and having a reduced and exteriorly threaded portion arranged in and detachably engaged with the boss and also having a comparatively large outer and interiorly threaded portion receiving the inner end of the handle; the handle and sleeve being adapted when the latter is disconnected from the boss to be folded with the conductor therein on the adjacent portion of the lamp.

3. In a therapeutic lamp, the combination of a socket, a conductor extending from the interior of the socket through an aperture in the side thereof and laterally from the socket, and a tubular handle receiving the conductor and disposed laterally to and detachably connected with the socket; said handle and conductor being constructed and arranged when the former is disconnected from the socket to be folded on the adjacent portion of the lamp.

t. In a therapeutic lamp, the combination of a socket having an aperture in its side, a switch plug disposed in said socket and havin a recess in its side and coincident with said aperture and also having binding posts on one end to which said recess extends, a conductor extending through said aperture and having branches disposed in said recess and connected to said binding posts, and a tubular handle disposed laterally to and connected with the socket and resocket, a tubular handle disposed laterally from said boss and attachable thereto, a conductor extending through said handle and boss and into said socket, and a sleeve interposed between the handle and said boss and bein adapted to connect the latter named mem ers.

6. In an electric therapeutic lamp, a hood, the latter being provided with a socket, a boss extending from said socket, a handle connected with said boss and extending laterally therefrom, said handle and boss being tubular, and the handle detachable from the boss and adapted to be folded on the adja cent portion of the lamp, and a current conductor which is passed through said handle and boss and into said socket and connected with the switch plug of the lamp.
