WALL PAPER CLEANING DEVICE Filed April 24, 1940 Patented Sept. 23, 1941 UNITED STATES PATENT OFFICE WALL PAPER CLEANING DEVICE John S. Lincoln, Des Moines, Iowa Application April 24, 1940, Serial No. 331,346

(oils-219) lever I1 is mounted on the shaft and provided 6 Claims.

There is in general use a Wall paper cleaning compound of a plastic nature, about the consistency of bread dough. It is generally used by grasping it in an operators hand and wiping it over the paper to be cleaned,and after one or two such operations it is kneaded by the operators hands to withdraw the soiled surface into the mass. This kneading operation is necessarily hard and slow work.

The object of my invention is to provide a device of simple, durable and inexpensive construction in which a quantity of wall paper cleaner is placed and a straight-edged portion thereof projected beyond the cleaner holder, and whereby the operator may grasp the handle of the cleaner and readily and easily wipe a relatively large area of wall paper in a single operation, and may conveniently and easily reach from a position standing on the floor of a room and clean all of the walls and ceiling.

More specifically, it is my object to provide a device of this class in which, when the projected portion of the cleaner has been used and become soiled, a very rapid and easy manual operation will move another portion of the cleaner to position to be projected beyond the holder and move the previously soiled portion toward the center of the mass of cleaner and apply a kneading operation to the cleaner and finally project a previously unused portion in a straight edged pattern beyond the holder.

In the accompanying drawing- Figure 1 shows a perspective view of my improved wall paper cleaning device;

Figure 2 shows a transverse sectional View of the same;

Figure 3 shows a detail transverse sectional View and illustrates the position of the cleaning plastic within the holder when the compressing and mixing member has been moved to open position and before the plastic has been rotated within the holder; and

Figure 4 shows a longitudinal sectional view on the line 4-4 of Figure 2.

My device comprises a cylindrical holder l having closed ends I I. At one side of the holder there is formed a longitudinal slot at l2, through which the plastic cleaner is projected for cleaning purposes. Adjacent this slot I 2 there is a relatively large opening at l3 for use in inserting cleaning plastic into the holder. A handle I4 is fixed to the holder.

Extended longitudinally through the central portion of the holder is a shaft I5 having at one with a spring actuated pawl It! to engage said ratchet for rotating the shaft. Fixed to the shaft on the interior of the holder adjacent each opening I3 is a cleaner compressing and mixing device comprising a curved wall 22 extended lengthwise of the holder throughout substantially the entire length thereof, and when in closed position, extended inwardly toward the longitudinal'center of the holder. At the inner end of this wall 22 is another wall 23 which extends outwardly to the inner wall of the holder, and when this device is in its closed position, as shown in Figur 2, these two walls substantially cover the entire opening I3. -A handle 24 is fixed to the wall 23. r

In practical operation the handle 24 is moved to position for moving the wall 23 outwardly to position for uncovering the refilling opening I3.

When the plastic has been inserted in the holder the handle 24 is moved to position adjacent the handle I4 and they are shaped so that both handles may be conveniently grasped in an operators hand. When this compressing and mixing member has thus been forced into its closed By this compression method the outer surface of the projected portion of the plastic arranges itself along a substantially straight line, and when this is applied to wall paper and wiped over the wall paper it is pressed by the operator against the wall paper so that the plastic cleaner adapts itself to the contour of the paper and completely wipes the entire surface covered by the wiping action. In practice, I have found that when this has been done with one wiping operation, the paper is thoroughly cleaned and all of the dirt upon the paper adheres to the plastic cleaner.

After this operation the operator moves the handle 24 to position bringing the wall 22 to a position substantially in line with the wall of the holder. This forms an open space, as shown at 25 in Figure 3, within the body of the plastic cleaner. Then the operator grasps the handle end a ratchet wheel [6. A manually operated I1 and rotates the shaft l5. vWhen this has been werked into the mass of the cleaner;

done the plastic-engaging fingers 20 will grip the mass of material and rotate it a small part of a revolution in the direction of the arrows shown in Fig. 3. This will first withdraw the projected portion of the plastic cleaner due to the adhesive qualityof the cleaner, and move the soiled portion of the plastic cleaner toward the right of the opening through which it was previously projected. Then, when the compressing and mixing member is again moved to its normal position, the previously soiled section of the cleaner will be moved inwardly" toward the longitudinal center. of th holder. very quickly and easily performed because it requires only a small amount of power to open and close the compressing and mixing member, and

only a slight amount of power to rotate the Obviously, this operation may be shaft I5 the small part of a revolution. However, with these two slight operations which must be performed after each wiping action of the. cleaner, the cleaning plastic isthoroughly kneaded and all of'the soiled surfaces thereof are I have found n practice that with my improved cleaning device a given quantity of the additional kneading operation is applied to the plastic compound by the kneading spiral Zl v 'Devices of this class are commonly known to the trade aswallpaper cleaners. They, however,

are useful in the cleaning of such things as win'dowshades, lamps, tapestries, tinted walls, pictures, kalsornined walls, etc.
