PAINT STRIPPER FOR USE ON WINDOWS AND THE LIKE Filed Aug. 25, 1960 2 Sheets-Sheet 2 States Pate This invention relates to a device specially adapted to strip paint from windows and the like and also for cleaning such surfaces.

Hitherto, paint that has got on windows during painting operations has required to be removed by scraping with the end of some sharp tool such as a knife or chisel. Also various types of handles and adaptors have been marketed to enable a razor blade to be used as a scraper. All these devices suffered from the defect that the blade area was too small thus rendering the work tedious. In addition, razor blades were liable to break.

It is an object of this invention to overcome these de fects by providing a device with a large blade surface, the said blade being reversible and adjustable.

The invention may be described as an improved stripper for paint and the like comprising a blade of rectangular shape of which two opposite edges are sharpened so as to be reversible within a clamp consisting of two flat sides which are connected together by a handle along one of their edges and which are adapted to receive the blade between them with a sharpened edge thereof protruding from the edges Opposite to that of the joined edges, the said sides being formed with slots for the passage of adjusting bolts which pass through holes in the blade so that the extent that the blade protrudes can be adjusted.

The invention will now be described with the aid of the accompanying drawings in which:

FIGURE 1 is a side elevation.

FIGURE 2 is an end view.

FIGURE 3a is a view of the blade in reduced size.

FIGURE 3 is a perspective view.

FIGURE 4 is a perspective view of a modification.

FIGURE 5 is an end view of the device shown in FIGURE 4.

FIGURE 6 is a side elevation of the device shown in FIGURE 4.

4 The blade 1 is preferably made from spring steel but any other material capable of being sharpened to give a blade that will retain its edge without frequent sharpening may be used. The blade is in the shape of a rectangular plate, the longer edges being sharpened to form reversible cutting edges 2 and 3'. The blade has four

holes

4, 5, 6 and 7 drilled through it at approximately the positions shown in FIGURE 3a which is on a reduced scale.

The blade holder shown in FIGURES 1 to 3 is in the form of a clamp and is made of a single sheet of plastic or other suitable material and consists of two similar

rectangular side plates

8 and 9 of a size just slightly larger than the blade, these two sides being connected along their upper edge by a substantially oval shaped hand grip 10 formed by an outwardly bulging of the two sides at their connecting edges. Two corresponding sets of

slots

11 and 12 are located in each side of the holder and parallel to each other.

The blade 1 is fitted between the

sides

8 and 9 of the holder as is shown in the drawings. Bolts 13 are inserted through the

slots

11 and 12 and through the sets of the

corresponding holes

4 and 5 or 6 and 7, according to which edge of the blade one desires to use, and tightened at the other side by butterfly nuts 13a. By loosening the nuts and moving the bolts up or down in the slots a smaller or larger area of the blade may be made to protrude from the blade holder, or the blade retracted within the holder so that a sharpened edge will not be exposed. The bottom edges of the sides are bevelled as at 14.

The device is used by gripping the handle 10 between thumb and fingers and pushing the blade along the surface of the window or other surface requiring stripping.

In an alternative embodiment as illustrated in FIGURES 4, 5 and 6, the device is provided with an upright handle 15. In such a case the holder may be conveniently moulded in two halves which are later secured together by joining the handle. In such a case where the device is provided with a handle the blade area is preferably somewhat smaller than that of the device shown in FIG- URES l to 3 for convenience of working.

I claim:

1; An improved stripper for paint and the like comprising a holder for a scraper blade of a rectangular shape having opposite sharpened edges, said holder comprising a pair of flat plates of a rectangular shape, said plates being joined together along one of their edges to form an oval enlargement and to provide a handle parallel with the opposite edges of said plates, said opposite edges of the plates being unjoined, said plates each having a pair of slots spaced apart and parallel with each other and perpendicular to said handle and to the unjoined edges to receive adjusting bolts passing through holes in the blade and to provide a 'dual clamping of the two plates against the blade and to provide a sliding rectilinear adjustment for said blade.

2. An improved stripper for paint and the like according to claim 1, wherein said oval enlargement of the joined portions of the plates includes a rearwardly projecting main handle portion disposed perpendicular to the oval 5 enlargement forming the parallel handle portion.
