RUBBING, SANDING OR POLISHING BLOCK Filed July 5, 1946 v A-r'roRNeY Patented Mar. 11, 1947 UNITED STATES OFFICE RUBBTNG, SANDING, OR POLISHING BLOGK Joseph :Fcild, JDetmit,,;Mioh. 7

'11 =Claims.
This invention relates to rubbing, sanding, or polishing blocks such as may "be 'used for preparing, cleaning, or finishing of fiat, rounded, or other surfaces, and has for its object to provide for a simple device characterized by a filler or core, preferably of a yielding nature enclosed in a fabric or similarpocket withmeans' for-drawing the upper edges or flaps 'of the pocket over the upper surfaces ofth'e core or fillerlnsuc'h-amanner that sla-c'kness will be taken out of the pocket and a compact structure result which will lend itself to the carrying out of rubbing, sanding, polishing, and othersi-m'ilar operations with-great facility and comfort to the operator.
More particularly, the said invention contemplates the combination with a filler enclosing pocket of a cover plate forming a major portion of the hand grip of the device and a closure plate for said pocket cooperatively coupled to the-said cover plate to engaget-he marginal fabric ofthe po"1et to tension the said fabric of the pocket about the enclosed core or filler.
Still further, the said invention contemplates the use, in cooperation with a'back' or cover plate for the device, a closure plate ex-tending thereunder and provided with means for engaging "the marginal portions of a core-enclosingpocket, together with a pressure plate extending over the back of the said core or filler, and means for effect- 'ing a separating movement of the two last 'mentioned plates in a manner effecting the tension of the material about the said core or filler.
Still further objects or advantages additional or subsidiary to the aforesaid objects, or resulting from the construction or operation of the invention as it may be carried into effect, will become apparent as the said invention is hereinafter further disclosed.
In carrying the said invention into effect, I may provide the novel construction and arrangement of parts hereinafter described, by way of example, having reference to th accompanying drawing, wherein:
Figure 1 is a longitu-dlnal vertical section of a rubbing block, :the 'partsbeing shown in a position occupied before tightening the pocket or cover about the rubber core;
Figure 2 is a similar view showing the position of the parts after tightening operation has been completed;
Figure 3 is a composite. figure showing in perspective the several partsvof the device disassembled;
Figure 4 is a plan of underside of thenmovable pocket-engaging. or closure plate; and
'Figurefi is a-similar view -'to Figure 1 showing a somewhat-modified form of the'device.
Similar characters-oi reference indicate similar parts in-theseveral figures of the drawing.
Ill indicates a pad or core preferably, but not necessarily, ofa resilient nature; and I prefer to use a fairly stifffform of "sponge rubber for the purpose. 'l is a pocket or cover, which for general use I prefer to construct of canvas, duck, or similar fairly coarse woven material, the said .pocke't being of a size and shape calculated to readily receive the said filler or core H]; and the sides of the said pocket'may be formed and permanently sewn togetheratthe seams as the drawlng indicates, although it may, of course, be simply folded from a flat sheet into such form about the sore or filler at the time-of assembly without such prefabricati'on, if so desired. It simplifies assembly of the device, especially by unskilled persons, if the sides of the pockets are prefabricated as suggested.
The sides and ends of the said pocket are characterized by their having extended flaps I2 and 13 which may be folded over the top of the core or filler after it is inserted into the said pocket;
and. :to engage. these flaps, I provide a closure plate 14 having spikes 15 extending upwardly along the marginal portions thereof over which spikes the said fiapsmay be pressed and engaged as will he obvious from the illustration.
in very'zconvenient way :of providing :for positioning of these spikes is simply to force staples it through the margins of. these plates so that basesof these staples will extend beneath the other side of the plate, as. seen in Figure 4, and one of the legs of each staple may be pressed downwardiy upon the upper surface of the plate to clamp thespilees firmly in position.
Located centrally of the closure plate is a threaded boss I?! and I further show the said closurepl-ate as beingzprovided with slots 1 8 which are illustrated as being toward opposite ends of thesaidiplata Directly overlying the core or filler If is a pressure platev L8 provided with upstanding tonguesifl adaptedto freely project through the slots .Ifiof the plate 14; and in assembling the device, the upper ends of these tongues 20 may be bent over asrat 2.:lto praevent complete separationof the two plates thereafter by permitting their limited separation as will beappa-rent. The 'tonguesifl also serve to maintain the closure and pressure plates in reasonably matched alignment.
When the flaps 1:2 and 13 of the pocket have been engaged with thespikes of the closure plate M in the manner previously described, the upwardly dished cover 22 is applied to conceal the so-engaged flaps of the pocket and also to protectively house the spikes of the plate M and the locking screw 23 is passed through the provided opening in the said cover plate and through the threaded boss ll of the closure plate l4 so that the lower end of the said screw will abut the pressure plate I9, Therefore, as the screw 23 is tightened it will cause the said closureplate l4 tol'be drawn upwardly from the pressure plate i5, thus drawing the fabric of the pocket ll tightly about the bottom and sides of the core or filler In as shown iii-Figure 2. Any undesirablelooseness of the pocket about the core or filler is thereby effectively taken up, and rubbing, sanding, polishing, or other similar operations may be comfortably and efiiciently performed with the device.
Obviously, the material of the pocket may be treated or impregnated with any suitable abrasive or polishing material, or it may be covered with sand paper or emery cloth folded thereabout and similarly engaged with the spikes of the closure plate l4. 7
In the modified form shown in Figure 4, the closure plate 34 corresponding to the plate M is made smallerthan the cover plate 22 so that, instead of engaging beneath the margins thereof as is the case of the assembly in Figure l,v it may being merely illustrative of a practical embodi-.
ment of the invention and not in a strictly limiting sense.
