atented Een. i5, QS@

attesta ortica My invention relates to apparatus for removing wall paper from the surface to which it is applied.

It is an object of the invention to provide a portable device for distributing water over the suriace of the paper and applying heat directly thereto so as to cause the water to penetrate the paper and loosen the paste holding the paper to the surface to which it is applied whereby it may be easily and quickly removed with a knife in the usual manner.

A further object of the invention is to provide a heating plate adapted to be moved over the surface of the paper to be removed and means for distributing water between the plate and pa- 15 per, the plate having means for conning the water within the area of the plate.

Another object of the invention 'is to provide a device of. the above-mentioned character which is simple and durable in construction, reliable 20 nrd eiicient in use and inexpensive to manufac- Other objects and advantages of the invention will be apparent during the course of the following description.

25 in the accompanying drawing, forming a part of this specication and in which like numerals i are employed to designate like parts throughout the same.

Fig. 1 is a vertical sectional view oi the device,

39 Fig. 2 is a front elevation of the same,

Fig. 3 is a horizontal section taken on line 3 3 of Fig. 2, and,

Fig. e is a horizontal section taken on line ii-t of Fig. `2.

35 In the drawing, wherein for the purpose of illustration, I have shown a preferred embodiment of my invention, the numeral 5 denotes a heating plate of substantially rectangular shape having a heating unit 6 attached to the back thereof 40 which is enclosed in the housing l. A bracket 8 is attached to the center of the back of the housing l which supports the vertical handle S by means of which the device is grasped in the hand. A wire i connects the unit 6 with a control 45 switch i i mounted on the bracket 8, which in turn is connected by the wire i2 to a source of electric current.

A water distributing chamber i3 is mounted above the upper edge of the heating plate and 50 is spaced therefrom by insulation or air it. The

chamber extends transversely of the plate, the front of the chamber being open yand covered with a ilexible cover i5 secured thereto by the frame it. A plurality of coil springs il' are disposed within the chamber between the back 5 thereof and the cover i5 which cause the cover to bulge outwardly beyond the face of the plate 5 and conform to the surface with which it is brought into contact. The bulged out portion of the cover is provided with a row of spaced open- 10 ings i8 which distribute the water from the chamber onto the surface of. the Wall. Theupper portion of the face of the plate 5 has a series of spaced vertical grooves i9, so that as the plate is moved over the wet surface of the paper, the ribs between the grooves will gradually heat the wetted paper and at the same time the water is trapped in the grooves to produce a scalding effect on the paper.

The water is admitted into the chamber i3 by 20 the needle valve 2t connected to the back of the chamber and communicating therewith. Dirposed beneath the needle valve is the main control valve 2i connected with the needle valve by the pipe 22. The stem 23 of, the valve 2i extends 25 through the plate 5 and has a head 24 on its outer end adapted to contact with the surface against which the plate 5 is placed. A ccilspring 25 mounted on the valve stem 23 between the body of the valve and the washer 26 normally 30 holds the valve in closed POSition, but upon contact of the head 2d with the Wall, the stem 23 is pushed inwardly opening the valve 2i. The valve 2i is connected 4with a tank of water 2l under pressure, or any other suitable water supply, by the conduit 28 which passes through the center of the handle 9.

Extending along the side and bottom edges of the plate 5 are channel members 29 adapted to receive flexible strips of suitable packing material 30. The flexible strips are retained in the channel members by a series of pins 3l having one end embedded in the strips and their oppo-` site ends extending through openings in the bottom of the channels and equipped with heads 32 45 which limit the movement of the pins and retain the strips in place. Coil springs 33 are mounted on the pins 3i between the bottom of the channels and the washers 34 mounted on the pins, which force the strips outwardly and cause them to conform with the surface of the wall with which they come in contact, thereby confining the water within the area of the heating plate.

In operation, the device is applied to the surface of the wallpaper to be removed and upon contact of the heating'plate 5 with the surface, the head 24 of the Valve stem 23 is forced inwardly against the tension of the spring 25, opening the valve 2i, so as to permit water to iiow through the needle valve 2U into the chamber i3 from which it is discharged through the openings I8 onto the surface of the paper. As the plate 5 is moved over the wetted surface the ribs between the grooves i9 gradually heat the wetted paper and the water is trapped in the grooves which produce a scalding eect that loosens the old paste instantly, so that it may be removed with a knife in the usual manner. The packing strips which surround the side and bottom edges of the plate 5 conne the water within the area of the plate.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or scope of the subjoined claims.
