1 Claim.

This invention relates to a holder for sandpaper.

An object of this invention is to provide a holder for sandpaper which includes a sheet metal body having a pair of parallel inverted U-shaped jaws within which a pair of upwardly convergent flanges carried by a bottom plate are adapted to be engaged, with the flanges having means at each end thereof to hold the bottom plate against endwise movement.

Another object of this invention is to provide a holder of this kind which is of simple construction and can be formed out of stamped sheet metal.

A further object of'this invention is to provide a holder of this kind wherein the bottom plate may be shaped in a manner to conform closely to the shape of the work which is being sanded.

With the above and other objects in view, my invention consists in the arrangements, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawing:

Figure 1 is a plan view of a sandpaper holder constructed according to an embodiment of this invention,

Figure 2 is a sectional view taken on the line 22 of Figure 1,

Figure 3 is a sectional view taken on the line 33 of Figure 2,

Figure 4 is a fragmentary sectionalview taken on the line 4-4 of Figure 3,

Figure 5 is a fragmentary sectional view taken on the line 55 of Figure 3,

Figure 6 is a detail end elevation of fled form of bottom plate,

Figure 7 is a detail end elevation of another modified form of bottom plate,

Figure 8 is a detail end elevation of another modification of this invention.

Referring to the drawing, the numeral l designates generally an elongated handle which is formed of sheet metal and includes a pair of downwardly convergent sides Ii which merge with a pair of downwardly divergent plates or walls l2. The plates or walls l2 have formed on the lower edges thereof inverted substantially U- shaped clamping members l3, the purpose for which will be hereinafter described. A bottom plate l4 of transversely arcuate configuration is provided in the opposite longitudinal edges thereof with a pair of upwardly convergent flanges l which are adapted to engage within the clamping member l3 and each flange I5 is a modiformed adjacent the opposite end thereof with detents I6 which provide a means for holding the flanges l5 and the bottom plate I 6 against endwise movement with respect to the clamping members I3. The bottom plate I 4 is formed with upturned opposite ends i1 and the lower side of the bottom plate 14 has secured thereto a cushion member IB. The cushion member i8 may be formed of either rubber, felt or the like and a sandpaper sheet [9 is adapted to engage under the cushion member [8 and the opposite longitudinal edges of the sandpaper [9 are bent about the flanges l5 as shown in Figure 3 and indicated at 20. The reverted or returned edges of the sandpaper [9 are adapted to engage in the clamping members l3 so that the clamping members I3 will firmly hold the sandpaper on the flanges l5 and under the cushion member 18.

Referring now to Figure 6 there is disclosed a modified form of bottom plate where in the plate member 2|, which is provided with theupwardly convergent side flanges 22, is formed with a transversely arcuate portion 23 having the concave side thereof lowermost and a cushion member 24 is adapted to be secured to the bottom' plate 2| by any suitable fastening means such as adhesive or the like.

Referring now to Figure '7, there is disclosed, a modification of the bottom plate generally designated as 25. The bottom plate 25 is formed with upwardly convergent side "flanges 26 and an inverted V-shaped intermediate portion 21. The inverted intermediate portion 21 is formed with right angular sides so that the right angled corner of a work position can be readily sanded. The bottom plate 25 is also provided with a cushion member 28 which may be formed of rubber, fibrous material or the like.

Referring now to Figure 8 there is disclosed another modification of bottom plate generally designated as 29 which is formed with V-shapeoi walls 30 having extending from the upper divergent edges thereof, upwardly convergent flanges 3|. A bracing plate 32 is fixed between the sides of the bottom member 29 and a cushion member 33 is secured in any suitable manner to the outer side of the bottom member 29. It will be understood that if desired, the bottom plate 29 may be formed with a convex wall which may be braced after the manner shown in Figure 8 so that concave surfaces may be readily sanded.

In the use and operation of this device the sandpaper 9 is cut somewhat larger than the width of the bottom member [4 and the longitudinal edges of the paper H! are then bent upwardly and downwardly over the convergent flanges IS. The bottom member is then pressed into the clamping members 13 and it will be understood that the divergent side members or plate I2 carried by the handle 10 are of resilient characteristic and may be biased outwardly so that when the bottom member is engaged with the clamping members the clamping members l3 will firmly hold the flanges of the bottom member in the clamping "members l3. The buttons or detents l6 engage in the opposite ends of'the clamping members [3 and hold the bottom member against endwise movement relative to the handle l0 and the divergent members l2.

This holder may be stamped or otherwise formed out of sheet metal having a resilient characteristic and where the "device -is" tobeuse'd in sanding a flat surface the bottom member, shown in Figure 3, will be used. By providinga slight curvature to the bottom member M, the sand paper l-9wil l tend to straighten :out "the curvature f of the "bottom member I' l and therefore-prevent undue engagement of the opposite longitudinal edges of the bottom member with the work.

I do notmean'to confine myself to the exact details of constructionherein disclosed but claim .all variations falling within the purview of-the appended claim.

What I claim is:

A sandpaper holder comprising an elongated handle formed of sheet metal, a pair of angularly inclined side portions diverging from said handle, a substantially U-shaped reverted downwardly opening clamping jaw carried inwardly of the lower edge of each portion, a bottom plate, upturned ends on said bottom plate, a pair of upwardly convergent, resiliently expansible identical flanges carried by the -'qp osite :longitudinal edges of said bottom plate and engageable with said jaws interiorly of said angularly inclined portions and a detent adjacent each end of each flange for holding said flanges against endwise movementrelative to said jaws.
