3 Claims. (01. 15-219) This invention relates-to improvements in .a device for holding wall paper cleaning compound and is an improvement on the device illustrated and described in Patent No. 1,999,462, issued to Casper and Anthony Kenne, said device consisting of a casing or container for supporting a cleaning compound such as is used for cleaning wall paper by hand, and including a slot in one end of one side of the casing, and means for forcing the material from within the casing and outwardly through said slot to form a cleaning portion extending laterally from the surface of the casing, and means for turning and kneading the material, the end member adjacent to the forward sideof the slot being inclined outwardly and forwardly-s as to permitthe material to be forced laterally from the sideusurface of the casing as it is moved longitudinally within the casing. Some difficulty has been experienced in forcing this material laterally and over the intendency to curve outwardly and 'r-earwardly so that it could not be withdrawn properly, and in such position thatthe rolling and kneading effect could be produced to the best advantage.

It is, therefore, the object of my inventionto provide an additional means wherein the forward side of the protruding portion of the cleaner may be held and retained against outward and lateral movement, permitting the back side to advance clined end surface in that the material has a so that the laterally projecting cleaning portion 2 will assume a moredesirable shape'and position, and further to providelmeans for reinforcing the front side of the cleaning portion to prevent shearing, of the portion over the outer edge of the front end member as the cleaning portion is movedlrearwardly over the surface to be cleaned. My invention consists in itheconstruction, arrangement and combination of the various parts of the device, whereby theobjectscontemplated' are attained,vas hereinafter more fully set forth, pointed out inrmy claims, and illustrated in the accompanying drawing, in which:

Figure 1 is a side elevation of a wall paper cleaner device involving my improvement;

Figure 2 is a top view of the same;

Figure 3 is an end view; and

Figure 4 is a detail longitudinal sectional view showing the manner in which my improved device is used in conjunction with the cleaning portion of the cleaner.

In the drawing I have used the reference numeral In to indicate generally a substantially rectangular casing l0 having a bottom I I, side members l2 and a front end member end member being preferably provided with an opening l4 and a hinged plate l5 supported adjacent to the inner face of the member |3 and hinged to the bottom plate H by projecting lugs it through suitable openings H in said bottom member, the end member I3 being inclined at substantially an angleof 60 from the horizontal, the plate l5 being provided with a transversely arranged and inwardly extending rib IS. The side members I2 are each provided with a horizontally arranged slot I9 for receiving a transversely arranged rod 20 on which is supported a top member 2| by means of upwardly extending lugs 22. A

slidably mounted on top of the bottom I and within the casing, is a plate 23 having a rearwardly extending portion 24 provided with a split looped portion 24a slidably mounted on the handle 34, hereinafter described. Pivotally mounted to each side of the portion 24 is a lever device 25, said lever devices having their upper ends pivotally connected to the outer end of the top 2| by means of a pin 26. A spring 21 is provided for yieldably holding the lower ends of the members 25 against movement from each other. The inner end of the member 23 is provided with an upwardly xtending portion28 to form an end member for the rear end of the casing.

slidably mounted on the upper edge of the member 28 is a plate 29 having downwardly extendingplates 33 slidably mounted on the plate 28. A'spring 3I-provides means for holding the plate 29 yieldably againstthe under surface of the plate 2|, the plates 30 and the end member 2Biforming what I shall term a plunger, the plate 28.also having forwardly extending side members 32 for scraping the sides of the members I2. Supported by each of the members 32 is an inwardly extending pin 33.

The bottom member II is provided with a handle member 34 to which is pivotally mounted the lever 35, said lever having a link 36 pivotally connected to the rearyend of the portion .24, thus providing means whereby when the lever 35 is actuated, the member 24 will be moved longitudinally of the plate II and carry with it the top plate 2|.

Supported transversely across the front side of the outer edge of the end member I3 is what I shall term a retarding bar 31 having its ends supported by means of spring Wires 38 supported adjacent to the outer surfaces of the wall members l2, at the points 39, thus providing means l3, aid whereby the bar 38 is yieldably mounted. The

upper edge of the bar 31 is provided with a series of inwardly and upwardly curved teeth 40.

The operation of the device is as follows:

The free end of the lever 35 is first moved forwardly causing the link 36 to be moved rearwardly and the plunger to be moved rearwardly, together with the top plate 2|. A chunk of cleaner is then placed in the casing with the material forced against the plunger and around the pins 33. The lever35 is then moved rearwardly, causing the'member 24, the plate 23 and the plate 2| to be moved forwardly. The lower ends of the members will then engage lug-s 4| carried by the handle 34, causing the plate 2| ,to be advanced at a higher rate of speed than the plate 23, tending to force the top of the material within the casing downwardly and forwardly. Further advancement of the member 24 will cause the members 25 to pass over the members 4| at the time the rod 20 reaches its forward limit of movement in. the slot l9, after which further movement of the member 24 will cause the plunger to be advanced relative to the plate 2| and the material to be forced against the plate I5 and thence outwardly and laterally through the slot 42 and between the inner edges of the plates 2| and 5 to form a protruding cleaner portion 43. As the material is. forced outwardly through the slot 42 the front surface of the cleaner portion 43 will engage the teeth 45, which will tend to retard the outward movement of the front face of said protruding portion and to cause the back face of said protruding portion to be advanced slightly relative to the front face, so that the member 43 will assume the position illustrated in Figure 4. The upper face of the member 43 may then be applied to the ceiling of a building to be cleaned, after which a rearward stroke of the handle 34, together with the cleaning portion 43, will cause the surface to be cleaned and the dirt to cling to the upper portion of said cleaner 43. This rearward movement will tend to move the protruding cleaner portion forwardly over the end of the members 40. Because of the fact that the bar 31 is mounted on yieldable wires 38, the said members 40 will also yield forwardly somewhat so as to prevent the upper surface of the protruding portion 43 from being sheared from the lower portion on a line even with the ends of the members 40. We find, also, that by providing the upper edge of the bar 3'! with teeth, that reinforcing portions 44 are formed in the cleaner between the teeth 40 which greatly assist in relieving the material of the shearing effect which would otherwise take place if the upper edge of the bar 3'! were smooth. In other words, the bar 31 and the teeth 40 provide a yieldable and simple flexible support for the forward surface of the cleaning portion. I find, also, that the cleaning portion is more readily disengaged at the time that the cleaning portion is drawn into the case It by the rearward movement of the plunger and the member 2|. This rearward movement of the plates 2| and 33 causes the portion 43 to be moved rearwardly away from the teeth 40 and the plate IE to be positioned as shown in dotted lines in Figure 4. Rearward movement of the free end of lever will then cause the plate 2| to move forwardly, which in turn will cause the portion 43 to be worked downwardly into the casing and that portion carrying the dirt, to engage the under plate I 5 at the time the material is again forced outwardly through the slot 42, so that a rolling and kneading effect is produced. This part of the operation is substantially the same as disclosed in the aforementioned issued patent, and my present inven- .tion pertains only to the bar 31 and the teeth 40 so as to decrease the shearing effect and to cause the cleaner portion 43 to assume a better shape than is possible by means of the plate l9 illustrated and described in said patent.

Devices of this class are commonly known to the trade as wall paper cleaners. They, however, are useful in the cleaning of such things as window shades, lamps, tapestries, tinted walls, pictures, kals'omined walls, etc.
