ATTORNEY United States Patent 3,410,035 SANDING BLOCK Ralph Gohde, 3022 Chester, North Bend, Oreg. 97459 Filed July 16, 1965, Ser. No. 472,612 2 Claims. (Cl. 51-391) ABSTRACT OF THE DISCLOSURE A body member which can be grasped for hand sanding operations. The body member has a slot at one end for anchoring one end of a piece of sandpaper and has a pronged gripping member at the other end for anchoring the other end of the sandpaper. The body member has top walls extending toward each other from the opposite ends. These top walls terminate short of each other to form a top opening compartment formed by the side walls of the body member and intermediate vertical wall portions.

This invention relates to new and useful improvements in sanding blocks.

In the sandpapering of various types of surfaces, and as well known, defects in the surface are filled with putty or the like and the area then sanded smooth. When such sanding is accomplished by hand labor, a supply of putty usually in a container must necessarily be kept handy. The use of such a supply container for putty, however, is inconvenient in use since the worker consumes considerable time in making frequent trips to the container to remove small amounts of putty therefrom as needed.

A primary object of the present invention therefore is to provide a sanding block which has, in combination, means for holding a strip of sandpaper in partially wrapped relation thereon and a top opening compartment or cavity for holding a supply of putty, whereby the putty is handy to the workman and he does not have to repeatedly remove putty from a container which necessarily must be kept in an out-of-the-way position and therefore an inconvenient position for reaching.

Another object is to provide a sanding block having a novel construction for holding a strip of sandpaper thereon, and also including a resilient pad on the bottom surface thereof.

Briefly stated, the invention comprises a sanding block having a body member in which is formed a top opening compartment or cavity for receiving a supply of putty or the like. The sanding block also employs means for releasably securing a strip of sandpaper thereon in extended position across its bottom surface. The invention will be better understood and additional objects will become apparent from the following specification and claims, considered together with the accompanying drawings, wherein the numerals of reference indicate like parts.

In the drawings:

FIGURE 1 is a perspective view of a sanding block employing the principles of the present invention;

FIGURE 2 is a longitudinal central sectional view of the sanding block; and

FIGURE 3 is an enlarged, fragmentary sectional view taken on the line 3-3 of FIGURE 2.

Referring now in particular to the drawings, the present sanding block comprises a body member having a full length bottom wall 12, full length side walls 14, and

walls

16 and 18, and

partial top walls

20 and 22 leading inward- 1y from the

end walls

16 and 18, respectively, and parallel to the bottom wall.

As stated, the

top wall portions

20 and 22 lead inwardly from the respective end walls. These top wall portions terminate short of each other, however, to form a top opening compartment or cavity 24 defined at the sides by side walls 14 of the body member 10 and at the ends by

vertical wall portions

26 and 28 leading downwardly 3,410,035 Patented Nov. 12, 1968 ice from the inner ends of

top wall portions

20 and 22, respectively. The compartment 24 is formed in the sanding block for the purpose of holding a supply of putty P in order that such putty will be conveniently avail-able to the workman and he will not have to be concerned with the repeated removal of putty from a separate container.

The body member 10 has an auxiliary end wall 30 spaced outwardly from the end wall 16 in parallel relation thereto and forming a part of the body member by integral connection with the side walls 14 of said body member. The auxiliary wall is not connected, however, to the bottom wall 12 and top wall portion 20 whereby to form a vertical, top and bottom opening socket 32.

Inserted in the bottom portion of socket 32 is one end of a resilient pad 34 which extends :along the bottom of the body member and upwardly partially along the end wall 18. The pad 34 is secured in place at one end by means of a screw 36 passing freely through auxiliary wall 30 and threadedly engaged in end wall 16 and at the other end by a screw 38 threadedly engaged in the end wall 18, the latter screw having a clamp plate 40 under the head thereof to securely hold this end of the pad in place.

A strip of sandpaper 42 is arranged to extend along the undersurfiace of the resilient pad 34 and up along the two ends of the body member. One end 44 of the sandpaper strip 42 is inserted in the upper open end of socket 32 as shown in FIGURE 2, to anchor said end, and the other end 46 of the strip overlies the top wall portion 22. For anchoring the end 46 of the sandpaper on this latter end of the sanding block, there is employed a gripping member 48 of inverted U-shape construction, having a pair of vertical legs or side walls 50 and a horizontal connecting portion 52. This gripping member is pivotally attached to the body portion by means of pivot pins 54 projecting through a lower portion of the legs 50 and the side walls 14 of the body portion 10. The pivot pins 54 preferably are located adjacent the outward edge of the gripping member whereby the forward or inner portion of said gripping member raises off the wall portion 22 when outward pivotal movement is accomplished.

The top wall portion 22 of the body member has one or more apertures 56, and these apertures are adapted to receive prongs 58 on the undersurface of the connecting portion 52 of the gripping member 48 when the latter is pivoted inwardly or downwardly into close association with the top wall portion 22. Prongs 58, in the down position of the gripping member, are adapted to pierce the end 46 of the sandpaper strip 42 which overlies the Wall portion 22. to anchor this end of the sandpaper strip on the block. As stated, the prongs may pierce the sandpaper, or if desired said standpaper may be provided with apertures 60 through which the prongs may easily pass.

Thus, the sandpaper strip is securely and readily anchored on the block. Furthermore, by utilizing a resilient pad between the bottom wall 12 and the sandpaper strip, a cushioned backing is provided for the sandpaper to accomplish an even overall sanding engagement with a surface and to prevent harsh sanding engagement in any one place. As stated above, the compartment 24 is adapted to receive a supply of putty and the putty is thus readily convenient for use by the workman as needed.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A sanding block comprising an integral body memher having end walls, side walls, and a bottom wall, a pair of top wall portions extending inwardly toward each other from said end walls but terminating short of each other, a pair of wall portions extending downwardly between the inner ends of said top wall portions and said bottom wall and forming with said bottom and side walls a top opening, putty receiving compartment whereby a supply of putty can be carried in the sanding block for easy access, and means at opposite ends of said body member arranged to hold a strip of sandpaper along the said bottom wall.

2. The sanding block of claim 1 wherein one of said top 'wall portions has at least one aperture therein, and including a gripping member pivotally mounted on said body portion and being movable between a first position closely adjacent said one top wall portion and a second retracted position, prong means on said gripping member arranged to project through said aperture in the first position of said gripping member and arranged in said position to pierce an end portion of a strip of sandpaper lying over said one top wall portion to anchor the end portion of the strip of sandpaper on the body portion, and means on the body portion opposite from said apertured top wall portion defining a socket for receiving the other end portion of a strip of sandpaper.
