Application January 14, 1949, Serial No. 70,936

2 Claims.

This invention relates generally to heaters and more particularly to a heater for paddle wax used in body and fender repair work, the heater including a receptacle for the wax which is maintained at a constant temperature, and the cover plate of the receptacle has incorporated therewith a plurality of containers for tinning solder, steel wool, cleaning fluid, and possibly other articles used by the repair man.

A primary object of this invention is to provide a device of the character described which will facilitate the proper heating of paddle wax or tallow to be used in coating paddles prior to their use in handling lead as in body and fender repair work.

An object of this invention is to provide a heater assembly in which the actual receptacle for the heated wax is largely covered by a cover plate having containers thereon for other materials used by the repair man.

Still another object of this invention is to provide a heater in which the thermostat for controlling the temperature of the wax and switch connected therewith is at least partially immersed in the wax, since this arrangement has been found to give more accurate temperature control of the wax.

Still another object of this invention is to provide a heater of the character mentioned above in which a floor of the wax receptacle, a baffle within the receptacle, and one of the vertical walls of the receptacle coact to provide support for paddles.

And a last object to be mentioned specifically is to provide a heater assembly of the character mentioned which is relatively inexpensive and practicable to manufacture, which is simple, safe, and convenient to use, and which will give generally efiicient and durable service.

With these objects definitely in view, this invention resides in certain novel features of construction, combination and arrangement of elements and portions as will be hereinafter described in detail in the specification, particularly pointed out in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a three-dimensional view of the assembled device;

Figure 2 is a vertical sectional view of the device, including representation of articles used therewith;

Figure 3 is a horizontal sectional view, taken on a horizontal plane immediately beneath the cover plate;

Figure 4 is an enlarged view of the thermostatically controlled switch; and

Figure 5 is a schematic view showing the electrical connections.

Similar characters of reference designate similar or identical elements and portions throughout the specification and throughout the different views in the drawings.

Referring now to the drawings in detail, this invention includes a receptacle having a front wall 10, side walls 12, and rear wall I4, all of which may be substantially vertical and integral with corner leg portions 16. A floor [8 is secured marginally to the vertical walls at a level above the leg portions l6 and an electric heater 20 is secured to the under surface of the floor l8, electric leads 22 being connected to the electric heater 2!].

In order to control the heating of the receptacle, there is provided a thermostatically controlled switch means including a fixed contact 24 supported on a plate 25, which is mounted on a pair of parallel braces 28. A coacting pivoted contact 30 is carried by the plate 26 and is operated by the wafer thermostat 32 which is mechanically connected to the pivoted contact by an inflexible link 34, the link being electrically insulated from the pivoted contact 30 by a sleeve 35 of some material having a high dielectric constant. It will be understood that the details of the thermostically controlled switch may be varied considerably all within the spirit of this invention. However, the positioning of the switch, in the present instance the positioning of the wafer thermostat 32 being the most important factor, is critical, since it has been found that best results are obtained when the thermostat 32 is immersed in the wax in the receptacle. Consequently, it is necessary to place the thermostat 32 on the floor l8 and it is preferred that the thermostat be of no great height, in order that it may ordinarily be completely covered with wax.

A plate 36 is rigidly secured within the receptacle and between the lateral walls l2, this plate being disposed vertically and parallel to the front wall ID. The plate 36 is also spaced above the floor l8 and spaced downwardly from a cover plate 38 which is rigidly secured to the walls of the receptacle. An intermediate portion of the cover plate 38 is bent upwardly, as indicated at 40, and the forward portion of the plate 38 does not extend to the front wall 10, the upper portion of the front wall being arcuately formed as indicated at 42 and the upper forward corner portions of the side walls I! being the said cover plate 38 comprising the floor of each of the containers, 48, 50 and 54. It will be .noted that the container 54 has its rear wall '56 reduced in dimension. A handle 58 is se-' cured to the wall 46.

The operation of this invention will be clearly understood from a consideration of the mechani-" cal details thereof, taken in connection with the drawings and with the above recited objects of the invention. 1 1 l In recapitulation, it may be noted that one or more paddles 60 will be placed in the compartment of the receptacle defined by the front wall It, side walls l2, and plate 36. This plate 36 guards the thermostatically controlled switch mechanism against injury by the paddles and at the same time coacts with the floor l8 and the arcuate edge 42 of the front wall in facilitating the positioning of the paddles 60 so that handle portions 62 thereof may extend from the receptacle while the other end portions 64 will be immersed in wax in the receptacle. Obviously, the wax in the receptacle will be maintained in molten state.

The container 48 will be used to storesticks of 1. A heater for paddlewax used in body and fender repair work comprising a receptacle having a cover plate with an opening therein and walls and a floor, an electric heater on said floor, a heat responsive switch connected in the leads of said heater and positioned on the upper surface of said floor so as to be normally in direct contact with wax in the receptacle and controlled by the temperature of wax in said receptacle, and a plate secured within said receptacle to guard said switch against injury by paddles and to coact with one of said walls and said floor to comprise a paddle support, said Plate being positioned above said floor.

2. A heater for paddle wax used in body and fender repair work comprising a receptacle having a cover plate with an opening therein and walls and a floor, an electric heater on said floor, a heat responsive switch connected in the leads of said heater and positioned on the upper surface of said floor so as to be controlled by the temperature of wax in said receptacle, and a plate secured within said receptacle to guard said switch against injury by paddles and to coact with one of said walls and said floor in supporting paddles, said cover plate having open-top containers thereon.
