Description

Aug. 17, 1954 G. A. WALLER 2,686,861 ELECTRICAL PAINT REMOVER Filed Feb. 17. 1951 magma n INVENTOR.
650,? 65/4. W44 L ER BY 1 A TTOR/VEX Patented Aug. 17, 1954 UNITED STATES PATENT OFFICE 2,686,861 ELECTRICAL PAINT REMOVER George Alfred Waller, Mount Vernon, N. Y. Application February 17,
1 Claim.
This invention the heating element and interfering with the proper functioning of the device. Also, it has been found, as in the case of using a blow-torch,
transmitting coating of such character that it is capable of withstanding the relatively high degree of heat to which it is sub- J'ected.
A further aim or object of my invention is to supply a heater which will do the intended work and the heating means of which may be brought into comparatively close relation to the 1951, Serial No. 211,533 (Cl. 219 21) painted surface without fire or electrical hazard and without danger of injuring the heater itself and without likelihood of causing the appliance to become gummed up or soiled or mechanically or electrically damaged by the heated plastic paint.
Another purpose of the invention is to supply a heater which will function in the specified manner and in which the heating element will be adequately protected and shielded against oxidation or deterioration and against mechanical injury.
To the accomplishment of these and other de- I have invented the present preof the drawing.
In the drawing:
Figure 1 is a front elevation of my device.
Figure 2 is a side elevation, partly in section, of my device.
Figure 3 is a section on line 33 of Fig. 2.
Referring to the drawing, it will be observed that my device includes a substantially square casing 4, the face 5 of which is open, the said case forming a heat reflecting unit. Within the case 4 is positioned a tray member 6, upon the a sheet of insulating magrooves or channels 9 which accommodate a zigzag coiled, electric heating element H) which is shielded from the work by the wall I I. Perforation l2, through the wall H exposing limited portions of the heating element l0 may be provide to afford circulation as an aid to convecbion heating. Preferably the terminals I 3 and M of the heating element are connected to the wires of cable !5 which passes through the handle 35 which is angularly attached to the case l by the tubular member H. As shown in Fig. 3, the case 4 is preferably equipped with a cover 18 which is adapted to be removably secured over the open face 5 by means of a suitable latch means I 6, the said cover being provided with a flange H? as indicated.
From the above it will be seen that I provide a. useful and novel appliance for the purposes specified in which the heating element is shielded and protected from the work of paint softening. It will be seen that the device is simple, inexpensive and of rugged construction. The tray 6 may be held in position within the case 4 by spot-welding or other suitable means and the block assembly may be removably held in place by means such as the screw 20.
When a layer of paint has been softened by the means described, it can readily be scraped off by any suitable implement.
The invention is not limited to the exact details of construction herein presented and modifications may be resorted to without departing from the spirit of the invention as established 15 by the scope of the claim.
I claim:
An electric paint softener including a hollow case member having one side open to form an open face and having the opposite side closed, a refractory block element exposing a substantially flat plane face to the open face of the case member, the block element having an open channel formed in the rear or inner opposite face of said block element facing in the opposite direction from its fiat face, an imperforate tray member secured Within the case member forming a ment freely mounted within the channel in said block element and concealed within the latter and facing the rear or closed side of said case member as well as the floor and insulating material between said floor and block element.
