Application May 18, 1950,'-Serial Nb. 162,715 I 3 lain1s. (01. 120-89) The present invention relates to an improved sandpaper holder and more particularly to an improved holder for conventional rectangularlyshaped pencil pointing sandpaper sheets.

It is an object of the present invention to provide an improved sandpaper holder adapted to securely holdconventional rectangularly-shaped sheets of sandpaper andexpose substantially all of the sandpaper surface for use. i r

Another object of theinvention is to provide an improved'sandpaper holder including'a backup plate having a portion shaped to engageand support the sandpaper sheets and a handleportion integrally formed with the backup portion, and a tray shaped to receive the backup portion of the plate and resiliently hold the sandpaper sheets against the plate.

It is also an object of the present invention to provide an improved holder adapted to receive a conventional pencil pointing paddle and securely hold conventional sheets of sandpaper on the paddle.

Other and more detailed objects of the invention will become apparent from a consideration of the following specification, the appended claims and the accompanying drawing wherein:

Figure 1 is a perspective view showing a plurality of sheets of sandpaper supported in an embodiment of the invention;

Figure 2 is a perspective view showing the pressure tray of the construction illustrated in Figure 1;

material, such for example, as aluminum and includes a rectangular backup portion l2 and a handlel portion Mintegrally formed with the backup portion [2. The rectangular backup .portion I2 is shaped to engage and support conventional rectangular sheets of pencil pointing sandpaper l6 throughout their entire area. The sandpaper holder also includes a tray l8 which is generally rectangular in shape and has upwardly turned flanges extending longitudinally thereof along its opposite edges and spaced to receive the rectangular backup portion l2 of the plate Hltherebetween. Each. of the flanges 20, at its opposite. ends,"is providedwith 'integrally formed inwardly turned tabs 22 adapted to overlie the upper surface of the rectangular backup portion [2 of the plate l0 when the latter is received between the flanges 20. The tray I8 carried a spring 24 formed of a strip of spring steel and having one end thereof secured to the tray in any suitable manner, as by the rivet 26. The spring 24 serves to urge the plate I 0 upwardly toward the tabs 22 and efiects a resilient gripping of the sandpaper sheets I6 between the upper surface of the rectangular backup portion I2 of the plate l0 and the tabs 22.

It will now be appreciated that the above described sandpaper holder is adapted to securely hold one or more sheets of the sandpaper l6 of conventional rectangular design and expose substantially all of the work surface of the sand- Figure 3 is a perspective view of the backup member of the construction illustrated in Figure 1; and

Figure 4 is a perspective view showing the pressure tray illustrated in Figure 2, applied-to a conventional pencil pointing paddle to securely hold in place the sandpaper forming a part of such paddles.

Pencil pointing sandpapersheets are conventionally sold in the form of rectangular pads secured to small wooden paddles having a rectangular portion supporting the pad of sandpaper sheets and a handle portion. In normal use one or more of the sheets of sandpaper, or frequently the entire pad, comes loose from the paddle, resulting in difficulty in holding the sandpaper during use thereof for pencil pointing. The sandpaper holder of the present invention positively holds the sheets of sandpaper and prevents their breaking away from or falling from the holder.

Referring to the drawing, the improved sandpaper holder of the present invention comprises a backup plate [0 which is formed of a solid flat paper, except for the small portions thereof which are covered by the tabs 22.

The present invention also contemplates that the tray l8 may be used without the plate II) as a holder for securing pads of sandpaper on the conventional wooden paddles upon which they are sold, to prevent the pads or sheets thereof from falling from the paddles. A conventional paddle is illustrated in Figure 4 at 28 and it will be readily appreciated that the tray 18 illustrated in Figure 2 may be readily applied to the conventional paddle as shown in Figure 4, and when so applied, will securely hold the sandpaper in may be made without departing from the spirit of the present invention.

What is claimed is:

1. A sandpaper holder for holding a plurality of sheets of sandpaper, comprising: a backup plate having a portion shaped to support said V 3. A sandpaper holder for holding a sheets of sandpaper; a handle member secured to said backup plate; a tray having a portion disposed below said backup plate and keeper elements extending to a point above and in overlying relation to the upper surface of said backup plate, with at least one end of said tray being open to allow sliding of a plurality of sheets of sandpaper between said upper surface of said plateand said keeper elements; and resilient means between said backup plate and the portion of said tray underlying said backup plate for urging said backup plate toward said keepervelements to grip said sandpaper between said keeper "ments at each end of said tray and opposite each other extending to a point above and in overlying relation to the upper surface of said backup 'plate, with at least one end of said tray being open to allow sliding of a plurality of sheets of sandpaper between said upper surface of said plate and said keeper elements; and a leaf spring secured at one end to said tray between said backup plate and the portion of said tray underlying said backup plate for urging said backup plate toward said keeper elements to grip said sandpaper between; said keeper elements and backup plate.

plurality 1 sliding of a plurality of sheets of sandpaper between said upper surface of said plate and said keeper. elements; and a leaf spring secured at oneend to said tray between said backup plate and the portion of said tray underlying said :backup plate for urging said backup plate to- V ward said keeper elements to grip said sandpaper between said keeper elements and backup plates.
