DANIEL M. WATSON, OF PORTLAND, OREGON.
ELECTRIC HEATING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 735,182, dated August 4, 1903.
Application filed August 19, 1902. Serial Not 120.243. (No model.)
To all whom it may concern:
Be it known that I, DANIEL M. WATSON, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Electric Heating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Myinvention relates to electric heating apparatus, and is adapted for applying heat lo cally in the manner usually employed with hot-water bottles.
The object of my invention is to construct a simple yet effective device for employing the heat derived from an. incandescent electric lamp or electric coil in the'warming of beds or the feet and for similar purposes.
Figure 1 represents a longitudinal section of my improved heater. Fig. 2 is a crosssection on the line 1 l of Fig. 1, showing the stays b. Fig. 3 is a cross-section on the line 4 4 of Fig. 4- Fig. 4 is a modification showing the heater closed at the extremity, with the end to which the lamp is attached open. Fig. 5 represents the same form as shown in Fig. 4, with a coil G employed in place of the incandescent lamp.
In the drawings, A is the framework of my heating-pad, formed of suitable wire. The upper portion is wrapped closely together, as shown at a, Fig. 1, and firmly held in position by soldering or otherwise, thus forming a substantial support for the lamp E. With the lower portion open, as in Fig. 1, the end supporting the lamp may be contracted to a size that will just receive the socket of the lamp, the bulb being inserted from the open end, while the body of the pad is expanded, giving room for the bulb to be held free from contact therewith and increasing the surface of the pad. In the body portion the wires are separated so as not to give unnecessary weight, and yet they are sufficiently close for strength. They are held from displacement by the stays'b at either side and the small Wires 0 at equal distances between them. The stays are secured to the wire frame by soldering or in any usual manner. Secured to the top of the contracted portion a of the pad is a spring-band (1, adapted to clasp the neck of the lamp-socket D, which is held firmlyby means of the screw c. When the lamp is in place,it receives the electric current by means of the conductor F, attached to any suttable line-wire or electric system and maybe operated justas an ordinary incandescent light. In the form shown in Figs. at and 5 the springband cl is secured to theframework a by means of the armsf, which are held in place in any usual manner, as shown in Fig. 3. It is essent-al to form the pad with one end open in order to admit of'circulation of air, and thus prevent the pad from becoming too hot.
Secured upon the exterior of the frame A is a covering of asbestos cloth B or similar material, which will prevent the rapid transmission'of heat and also prevent injury from burning, while at the same time it prevents the wire frame from coming in contact with the body receiving the heat. Over the asbestos covering I place a final exterior covering 0. This I make of a cloth having a smooth surface, and when properly secured gives the pad a neat finish.
The framework is sufficiently strong for the protection of the lamp and for its own preservation, and its resiliency allows of a slight yielding from pressure, so that injury will not result from contact with the pad.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In an electric heating apparatus, a receptacle consisting of a wire framework provided with stays and having a flexible covering and having one end open and means attached to said framework for supporting an electric lamp, whereby said lamp is held within said receptacle, substantially as specified.
2. In an electric heating apparatus, aframe- 10 supporting said electric coil and arms secured to said framework at one endand at the other to said spring-clasp, whereby said coil is held within the pad, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
DANIEL M. WATSON.
