SANDING BLOCK Filed Feb. 17, 1940 Patented July 8, 1941 ssrmmoamcn James F. McAdam, Worcester, Mala, assignmto ParkerWire Goods Company, Worcester a corporation of Massachusetts Application February 17, 1940, Serial No. 319,376
12 Claims.
The present invention relates to a sanding block adapted for releasably holding a strip of sandpaper or a roll of sandpaper so that the abrasive surface may be replaced. The principal feature of the invention is the comparative simplicity of the device and its ease of assembly, making it inexpensive to manufacture and convenient to use. The block is adapted to hold a reserve supply of sandpaper in the form of a roll so that the worn sanding surface may readily be replaced by shifting the sandpaper endwise on the device. The block may readily be formed from sheet material, and when so formed, no machining or other operations are necessary after the parts have been bent into the proper shape.
Other features and advantages of the invention will more fully appear from the following detailed description taken in connection with the accompanying drawing in which- Fig. 1 is a side elevation of a sanding block embodying the invention.
Fig. 2 is a sectional view along the line 2-2 of Fi 1.
Fig. 3 is a sectional view along the line 3-3 of F18. 2.
Fig. 4 is a perspective view of the top member. Fig. 5 is a perspective view of the bottom member.
The device as shown has a top or cover I and a base 2, these parts being separable from each other and resiliently held together to clamp therebetween a strip of sandpaper 3 of any suitable type, as for example, the familiar abrasive coated cloth or paper. A pad 4, preferably of vsponge rubber or other correspondingly resilient material, is positioned between the underside of the base and the operative surface of the sand- The base 2, which in the arrangement shown, is formed from sheet material, has a flat central portion 5 against which the pad 4 rests, the central portion having depending flanges I at opposite edges to hold the pad in position. The portion 5 may also have integral depending prongs l which project into and more securely .hold the pad 4 in place.
At the opposite ends of the central portion 5 of the base are upwardly extending end mem-' bers 8, the upper extremities 9 of which are bent inwardly and downwardly to form inverted loops. The material of the base is more or less resilient so that the end members 8 may be spread apart to receive therebetween the top, as will hereinend members I of the base is an upwardly projecting flange it which is struck up from the central portion of the base and which is substantially as wide as the central portion. This flange acts to retain the unused end of the strip of sandpaper, which has been coiled intoa roll ll of sandpaper, in position between the top and the base and also serves to aid in retaining the top in proper position on the base, as will be pointed out.
The top, which is entirely separable from the base, may be readily formed from sheet material and has .a substantially flat central portion I! with depending side flanges l3 spaced apart to correspond substantially to the width of the base and extending approximately into coinciding relation with the opposite side edges of the base. Thus the upwardly extending flange ll engages the inner surfaces of these side flanges and aids in supporting the top against tilting with respect to the base. From the ends of the central portion of the top are downwardly extending flanges II, the spacing of which is slightly less than the spacing of the upturned ends 8 of the base so that these end flanges will be positioned between and in engagement with the inner sides of the inverted loops of the end a members of the base. The lower extremities of these end flanges it are turned inwardly toward each other as at it and are spaced from the central portion of the top so that by engagement with the base they will retain the top in the desired position. The top is preferably formed from a somewhat resilient material sothat the 88 end flanges thereon will be resilient, and when the top and base are assembled, will engage resiliently against the upwardly extending end members on the base for clamping the sandpaper strip therebetween.
40' The mode of assembly of the parts of the device will be readily apparent. The sandpaper strip is coiled and placed within the base as shown, with the end of the strip extending around the base on the underside of the pad and over the end member I remote from the roll. The top is then pressed downwardly with its depending end flanges located between the endmembers of the base for holding the sandpaper strip in position.
When the operative surface of the sandpaper requires replacement, the top is pulled away from the base and the strip is moved endwise until an unused portion of the strip underlies the pad and the top and base are then reassembled.
. Although sandpaper has been referred to enafter appear. Between the upwardly extending tirely throughout. it will be apparent that emery cloth or em'ery paper, or. other abrasive strips, may be used equally well and the term sandpaper is used generically.
