2 Claims.

The present invention relates to new and useful improvements in sanding devices for sanding the surfaces of work to be painted or otherwise refinished and especially to a sandpaper holder adapted for rubbing over the surface of the work.

The primary object of the invention is to provide a sandpaper holder of this character embodying means for supporting a roll of "sandpaper in position for feeding a fresh section of the paper under the bottom of the holder and clamping the same in position thereto.

A further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation, as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like reference numerals refer to like parts throughout, and in which:

Figure 1 is a top plan View showing my improved sandpaper holder,

Figure 2 is a side elevational view of the sandpaper holder,

Figure 3 is a side elevational view showing the upper clamping block for the sandpaper holder, raised for receiving an edge of the paper,

Figure 4 is a longitudinal sectional view of the holder taken substantially on a line 44 of Figure 1,

Figure 5 is a transverse sectional view taken substantially on a line 5--5 of Figure 4.

Referring now to the drawings in detail, wherein, for the purpose of illustration, I have disclosed a preferred embodiment of the invention, the numeral 5 designates the sandpaper holder generally, which includes upper and lower clamping blocks 6 and 1 arranged in superposed relation, the opposed faces of the blocks having a coil spring 8 recessed therein for urging the upper block 6 upwardly from the block I in a separated position, as shown in Figure 4 of the drawing.

To the upper surface of the block 6 is secured a metal plate 9 having a downturned flange III at its front end positioned against the front edge of the block 6.

The rear end of the plate 9 is rolled under to form a tube I I adapted for holding a roll of sandpaper I2, the free edge of the tube being spaced from the underside of the plate 9 to provide an opening I3 from which the sandpaper may be unrolled to travel rearwardly under the tube.

The rear of the block 5 projects rearwardly beyond the upper block 6 and is formed, in its upper surface, with a transversely extending, shallow groove I4 in which the bottom of the tube. I I is seated to frictionally hold the sandpaper in the groove at the underside of the tube.

The end of the sandpaper is extended downwardly over the rear end of the block 5 and under the bottom thereof and then upwardly at the front of the block 5 and inserted rearwardly between the front ends of the blocks 6 and 'I, as indicated in Figure 4 of the drawing.

A pair of anchoring pins I5 project downwardly from the underside of the block 6 adja cent its front end and are adapted to penetrate through the sandpaper to retain the latter in position between the blocks, the lower ends of the pins I5 being seated in recesses I6 in the upper surface of the block 1.

To the underside of the block I is secured a felt pad I! and under which the sandpaper is positioned, the felt pad yielding to downward pressure exerted on the holder.

The ends of the roll of sandpaper I2 are secured against accidental displacement laterally in the holder by means of longitudinally extending flanges I8 positioned at opposite sides of the upper block 6 and projecting rearwardly at each end of the tube I I. The flanges I8 project downwardly from the outer edges of plates l9 overlying the top of the block 6 and pivotally secured thereto by screws or the like 29).

The flanges I8 and plates I9 may be swung outwardly into the dotted-line position as shown in Figure 1 of the drawing to permit insertion of a fresh roll of sandpaper I2 into the tube II.

The holder 5 constitutes a hand-operated sander adapted to be grasped by the hand of a person for movement over the surface of the work, the downward pressure of the hand of the operator on the upper block 6 serving to maintain the blocks in close contacting relation to thus prevent removal of the sandpaper at the front ends of the blocks.

' When it is desired to bring a fresh, unused section of the sandpaper into use, pressure is released on the upper block 6, permitting the spring 8 to separate the blocks whereby the front end of the sandpaper may be disengaged and a fresh section of sandpaper unrolled from the roll I2 and pulled forwardly under the lower block I, the used portion of the sandpaper then being torn off and the end of the paper again secured between the blocks 6 and I.

In view of the foregoing description taken in Having thus described the invention, what I claim is:

1. A sand paper holder comprising a pair of clamping blocks arranged in superposed relation, the rear end of the lowermost block projecting beyond the upper block and formed with a transverse groove providing a seat, a tube carried at the rear end of the upper block and disposed in' said seat: with a front opening therein, a roll or sandpaper inv the tube; having a free end extending out of said opening and. rearwardly between said tube and. seat and trained forwardly under the lower block with its: terminal. edge interposed between saidblo'cks, and means for attaching said terminal edge: between the blocks.

2. A sandpaper holder comprising a pair of. clamping blocks arranged in superposed relation,

the rear end of the lowermost block projecting beyond the upper block and formed with a transverse groove providing a seat, a tube carried at the rear end of the upper block and disposed in said seat with a front opening therein, a. roll of sandpaper in the tube, having a free end extending out oi. said opening and rearwardly between said tube and seat and trained under the lower block with its terminal edge interposed between, said blocks, said tube irictionally binding said free end against said seat, and means at the ends of the tube for retaining the roll therein.
