Description
Aug. 15, 1961 J. T. GHERICICH ELECTRICALLY HEATED PAINT AND VARNISH REMOVER Filed Dec. 21, 1959 INVENTOR J.T. GHERICICH' Alld l 1 United States Patent 2,996,596 ELECTRICALLY HEATED PAINT AND VARNISH REMOVER Joseph T. Ghericich, 101 River-view Drive, Stuart, Fla. Filed Dec. 21, 1959, Ser. No. 860,798 4 Claims. (Cl. 219-29) This invention relates to a paint and varnish remover and more particularly to electrically heated scraper apparatus adapted to remove paint, varnish and other materials from coated surfaces.
It has heretofore been proposed that heated element be passed over a paint or varnish surface followed by a scraper element. Such devices, however, have not proved successful, due to the failure to recognize additional important and essential features. The structures have either allowed the heating element of its own weight to rest upon the surface and without additional pressure, or else have required that the pressure be transmitted through a single handle rigidly supporting the heating element and the scraper. They have not provided means for differentially exerting pressure upon the heating element and upon the scraper element so that the desired pressure for the heating element may be employed with respect to the particular type of paint or varnish being removed and at the same time the required pressure for the scraper being applied through flexible means directly to the scraper.
An object of the present invention is to provide a new and improved paint and varnish remover apparatus, including a weighted electrical heating element for loosening the film or layer of paint or varnish and a scraper element, in which the scraper is flexibly mounted with respect to the heating element for pressure movements in suificient amounts independently of the heating element for quick removal of the film or layer loosened by the heating element.
Another object of the invention is to provide a new and improved electrically heated paint and varnish remover of the above type which is simple in construction, relatively inexpensive to manufacture, and thoroughly reliable and efficient in use.
With these and other objects in view, which will become readily apparent from the following detailed description of the various unique, practical and illustrative improvement shown in the accompanying drawing, the present invention comprises the novel elements, features of construction and arrangement of parts in cooperative relationship, as more particularly indicated and defined by the hereto appended claims.
In the accompanying drawing:
FIG. 1 is a plan view of an electrically heated paint and varnish remover apparatus constructed according to the preferred embodiment of the present invention;
FIG. 2 is a side elevation of the structure shown in FIG. 1;
FIG. 3 is a rear end view looking at the scraper element.
FIG. 4 is a detail vertical section taken along the line 44 of FIG. 1; and
FIG. 5 is a detail section taken along the line 55 of FIG. 1, the scraper blade being shown depressed with respect to the heater so as to illustrate the manner in which the film of paint loosened by the heater is peeled from the painted surface.
Referring to the drawing, the new and improved paint and varnish remover may comprise a heater in the form of a heated pressure device 11 of suitable construction.
In the illustration given, the heater 11 comprises a hollow casing 12, having a front end wall 13, a rear end wall 14, and a flat bottom wall 15 arranged to pass over a painted or varnished surface 16 for the purpose of loosening the film or layer 17 of paint or varnish thereon.
Patented Aug. 15, 1961 Within the casing 12 is a resistance element 18 which is adapted to be connected to a source of electrical power by means of a cable 19. Overlying the resistance element 18 is a layer of asbestos 20.
In view of the well-known construction described, it is believed unnecessary to set forth further details.
According to the present invention, alined notches 2-1 and 22 are respectively formed in the upper portions of the front and rear walls 13 and 14.
Extending across the top of the casing 12 and arranged within the notches 21 and 22, is a handle bar 23 having a length somewhat greater than the length of the casing 12. Thus, the construction and arrangement of the parts is such that the forward end of the handlebar 23 terminates a suitable distance beyond the front end 13 and the rear end of the handle bar 23 terminates a suitable distance rearwardly from the rear wall 14 of the casing 12, where it is directed downwardly and widened to provide a vertical scraper blade 24 having its bottom formed with a cutting edge 25.
Mounted on the forward end portion of the handle bar 23 is a front handle 26, and mounted on the handle bar and disposed near the rear end portion thereof, is a rear handle 27. It will be noted that the two handles 26 and 27 are suitably spaced apart and conveniently arranged to be grasped by the hands of an operator so that pressure can be applied to the device to effect removal of paint or varnish in the manner to be hereinafter more fully de scribed.
At suitably spaced apart intervals, the handle bar 23 is formed with a pair of holes 28, into each of which is inserted a post 30, having a head 31 formed at its upper end and its lower end mounted in a threaded hole 32 formed in the bottom wall 15, whereby said post is fixedly secured within said casing 12.
Encircling each post 30 is a coil spring 33. One end of the spring 33 bears against the underside of the handle bar 2 3 to thereby keep said handle bar engaged with the head 31 of the post, and the other end of said spring bears against the upper face of the asbestos 20.
It will be noted that the purpose of the springs 33 is to normally maintain the handle bar 23 in a predetermined position within the casing 12 above the bottom of the notches 21 and 22 so that the edge 25 of the scraper blade 24 barely touches the painted surface 17 (FIG. 2), and to permit actuation of said handle 'bar as a unit relative to said casing, during operation of the device, to move the scraper blade 24 downwardly into the film 17 of paint or varnish (FIG. 5). Thus, the construction and arrangement of the parts is such that the handle bar 23 is connected to the casing 12 so that when operating pressure is applied to the handle bar, such pressure is transmitted through the springs 33 to permit the scraper to engage the painted surface, and at the same time enable the heater to engage the painted surface with sufiicient pressure to loosen the film 17 of paint or varnish therefrom. Also, due to the resilient manner in which the handle bar 23 is operatively connected with the heater 11, the operator can maintain the desired pressure upon the heater to effectively loosen the film of paint or varnish from the painted surface so that the scraper blade 24 will, when the handle bar is depressed, quickly peel the painted surface film when the device is moved in the direction of the arrow in FIG. 5.
It will be noted that the holes 28 in the handle bar 23 are larger in diameter than the diameter of the posts 30. This construction permits the handle bar 23 to be freely moved with respect to the heater 11 so that the scraper blade 24 can be rocked sideways and endways, as well and upward and downward with respect to the heater 11 when irregular surfaces are encountered. At all times the bottom of the heater will remain flat on the surface being worked on, so that there will be full coverage of heat before the scraper blade 24 is brought into peeling position with the film of paint or varnish on the preheated surface.
In operating a device of this character, it is found that different surfaces of different contour and particularly moldings and trims require diiferent types of scraper blades. With the apparatus shown, a. scraper blade of the type needed by the particular painted coating can be substituted for the scraper blade 24, and various shaped plates conforming to the contour of such substituted scraper blades can be attached to the bottom wall 15 to facilitate removal of paint from the surfaces of different contour.
While I have described the invention in great detail and with respect to the present preferred form thereof, it is not desired to be limited thereto since changes and modifications may be made therein without departing from the spirit and scope of the invention. The invention may be embodied in other specific forms without departing from the essential characteristics thereof. The present embodiment is therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced there- What is claimed is:
