IN VE N TOE fl/vofps FASMI/aSE/V Smears/v A T TO ENE Y5 United States Patent 3,363,316 WALLPAPER REMOVING DEVICES Anders Rasmussen Skarsten, Welwyn Garden City, England, assignor to Slrarsten Manufacturing Company Limited, a British company, Welwyn Garden City, Hertfordshire, England Filed July 19, 1966, Ser. No. 566,304 Claims priority, application Great Britain, July 20, 1965, 30,867/ 65 7 Claims. (Cl. 30-171) The invention relates to a wallpaper removing device for use for example by interior decorators.
The invention provides a wallpaper removing device comprising a strip of stainless steel or the like, one end portion of the strip being bent at approximately right angles to the strip and being provided with a set of teeth along the end for scratching or scoring a wallpaper surface and the other end portion of the strip being bent to lie at a small angle to the strip on the same side of the strip as the teeth, the said other end portion providing a wallpaper stripping blade.
Preferably the teeth are set at the pitch of three sixteenths of an inch.
The blade may be chamfered along its edge nearer the plane of the strip.
In a preferred embodiment the strip is provided with means for attachment to a handle, locating means being provided for locating the strip on the handle with either the teeth or the blade in an operative position.
The invention further provides a wallpaper removing tool comprising a wallpaper removing device as just described in combination with a handle, the strip being attached to the handle which extends generally parallel to the strip with either the teeth or the blade projecting therefrom.
The strip may be attached to the handle by means of a single screw which is releasable to allow rotation of the strip relative to the handle.
In one arrangement the handle has a portion which is adapted to engage a wallpaper surface when the teeth and/or the blade is at a desired operating angle with regard to the surface.
A specific example of a wallpaper scraping tool according to the invention will now be described with reference to the accompanying drawings in which:
FIGURE 1 is a side elevation of the tool,
FIGURE 2 is a plan view of the tool,
FIGURE 3 is an end view of the tool, and 7 FIGURE 4 is an end view of the tool with the teeth and blade reversed.
Referring to FIGURE 1 the tool comprises a handle 10 and a short length of stainless steel strip 11 attached to one end of the handle. One end portion 12 of the strip 11 is bent at right angles to the plane of the strip and is provided with teeth 14 with a pitch of three sixteenths of an inch. The other end portion 15 of the strip is bent to lie at a small angle to the strip and provides a stripping blade 16. The blade 16 is chamfered on its upper edge.
The teeth 14 are adapted to scratch or score a wallpaper surface and the blade 16 is arranged to strip wallpaper once the wallpaper has been softened by water or the use of a liquid remover.
There is a central hole 17 in the strip 11 and a corresponding passage 18 in the handle 10. The strip is held on the handle by means of a screw 19 which passes through the hole 17 and the passage 18 and makes screw threaded engagement with a nut in a boss 20. There is a domed washer 21 between the screw head and the strip 11 and a flat washer 22 between the handle and the boss 20. There is also a flanged metal plate 23 on the underside of the handle.
The strip 11 is located to lie in the fore and aft direction of the handle 10 by means of two holes ,(not shown) in the strip one on either side of the hole 17 and in line with the handle 20. The holes make engagement with a corresponding stud projecting from the metal plate 23. The stud engages with one of the holes when the strip 11 is in the position shown in FIGURES '1 to 3 and with the other hole when the strip is in the position of FIG- URE 4. v
To rotate the strip from one position to the other the boss 20 is rotated to slacken the screw 19 and the boss 20 is tightened when the strip is in the desired position.
The hole 17 is of greater diameter than the screw 19 and there is a cylindrical flange projecting from the plate 23 which makes engagement with the sides of the hole 17. In this way the strip 11 is located without wear on the screw 19.
The handle 10 has a portion 25 which is arranged to slide along a wall, or other surface to which Wallpaper is attached, in use of the tool as will now be described.
In use of the tool the strip 11 is first set on the handle with the teeth in an operative position as shown in FIG- URE 4. The teeth are then moved backwards and forwards over the wallpaper surface to score or scratch the surface.
When the wallpaper surface has been scored or scratched a liquid wallpaper remover or plain water is applied to soften the paste which is securing the wallpaper to the surface. The strip 11 is then reversed on the handle to the position shown in FIGURES 1 to 3.
The blade 16 is then used to strip the wallpaper from the surface by pushing the tool along with the blade 16 foremost and with the portion 25 of the handle resting on the surface to ensure that the blade 16 is set at the correct angle to the surface.
1. A wallpaper removing device comprising of a strip of rigid material, one end portion of the strip being bent at approximately right angles to the strip and being provided with a set of teeth along the end and the other end portion of the strip being bent to lie at a small angle to the strip on the same side of the strip as the teeth, the said other end portion being formed as a wallpaper stripping blade and a handle detachably secured to said strip, a portion of said handle extending rearwardly and downwardly from said strip to engage a wall surface to hold said set of teeth off the surface when said blade is in use.
2. A device according to claim 1 in which the blade is chamfered along its edge nearer the plane of the strip.
3. A device according to claim 1 in which the strip is provided with means for attachment to said handle, and locating means for locating the strip on the handle with either of the teeth and the blade in an operative position.
4. A device according to claim 1 in which the strip is attached to the handle by means of a single screw which is releasable to allow rotation of the strip relative to the handle.
5. A device according to claim 1 in which the teeth are set at a pitch of three sixteenths of an inch.
6. A wallpaper removing device having:
(a) a strip of stainless steel (b) an end portion at the end of the strip bent at approximately right angles to the strip provided with teeth (c) an end portion at the other end of the strip bent to lie at a small angle to the strip on the same side as the teeth and chamfered along its edge nearer the plane of the strip thereby to form a scraper blade (d) a handle extending generally parallel to the strip (e) a single screw at the center of the strip passing through the strip and engaging the handle for attachment of the strip to the handle and releasable to allow rotation of the strip relative to the handle (f) means to locate the strip on the handle with either of the teeth and the blade extending forwardly from the handle in the operative position, and
(g) a portion of the handle extending rearwardly and downwardly from the strip to engage a wallpaper surface behind the strip when the blade is in the operative position and to hold the portion of the strip behind the blade ofi the surface when the blade is in scraping contact therewith.
7. A device according to claim 6 in which the teeth are set at a pitch of three sixteenths of an inch.
