This invention relates to devices used for cleaning surfaces, and more particularly for cleaning windows after painting.

()ne of the objects of this invention is to provide a device in which the blade of socalled safety-razorscan be used, having a handle member and having clampin means by which the razor-blade can be firmly held.

Another object is to provide a device of this type with yieldingly connected clamping means on a handle.

another object is to provide a yieldingly connected clan'iping-end on a handle with controlling means of an elastic nature, as a spring, interposed between the handle and the yielding clamping member.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in whicl Fig. 1 is a top plan view of a scraper of a simple form embodying this invention.

Fig. 2 is a fragmentary section on line 2-2 of Fig. 1.

Fig. 3 is a fragmentary section similar to the one illustrated in Fig. 2, having a flat or leaf-spring for controlling the yielding blade-holder instead of coil-springs indi-' cated in Figs. 1, 2 and f.

Fig. at is a cross section through the bladeholder and the blade on line l4=of Fig. 1.

In painting windows it is quite a task and practically impossible to avoid getting paint over the glass in the window, and it is a common practice to remove the paint from the glass of the window, after the painting by scraping, for which purpose worn-out razonblades are very useful.

One of the principal objects of this invention is therefore to provide a practical, useful, and handy tool, by which such razor-blades can be used more readily and easily.

As illustrated in the drawing, the razorblade 5 is disposed between two hingedly connected

plates

6 and 7. The hinge-pivot 8 is formed by the ends of the wire 9. This wire 9 is mounted in a handle 10, Other wires 11 are secured to the first-named wire 9 at 12, as by soldering, welding, or in any other similar suitable manner. The free ends 13 of the wires 11 extend over the blade holder, formed by the

plates

6 and 7, and are spaced above the holder, an that SCRAPER.

springs 14 can be disposed between the holdor and the ends 13.

The springs 1 1 have the tendency to force the holder with the inserted blade 5 downwardly, however allowing a yielding of the holder with the blade when the handle is pressed downwardly in excess of the normal tension of the springs, thereby preventing to, a great extent a scratching or marring of the window-glass. i

A screw 15 1's provided for clamping the two

plates

6 and 7 together, and thereby causing a firm holding of the razor-blade 5, making an exchange of the razor-blade easy and convenient.

To facilitate a quickand proper locating of the razor-blade betweenthe two

plates

6 and 7, small pins 16 are preferably pro vided, as illustrated in Fig. 1, to engage in the perforations of such razor-blades.

A slightly modified form of yielding means between the handle and the razorblade-holder is illustrated in Fig. 3, in form of a flat or leaf-spring 17. Such and other slight modifications can, of course, easily be arranged within the spirit and. scope of this invention.

Having thus described my invention, I

claim:

1. In a scraper, a blade-holder, a handle having means to movably connect the bladeholder to the handle, and elastic means between the blade-holder and the handle to allow a yielding of the movably connected blade-holder in relation to the handle.

2. In a scraper, a blade-holder, a handle embodying means for hingedly connecting with the blade-holder and other means to extend to a point over the hingedly connected blade-holder, and yielding means between the handle and the holder.

3. In a scraper, a blade-holder consisting of hingedly connected members between which a scraping blade can be firmly held and means, for firmly holding the hingedly connected members clamped together, a liandle embodying means for connecting with the hinge of the blade-holder and means to extend to a point over the hingedly connected blade-holder, and yielding means between the handle and the holder.

In testimony that I claim the foregoing as my invention 1 have sinned in name.
