HAND SANDER Daniel Epner, New York, N. Y. Application November 10, 1938, Serial No. 239,857 1 Claim. (Cl. 51—187)

My invention relates to improvements in grinding, abrading, polishing and cleaning devices, and it is the principal object of my invention to provide a comparatively simple and therefore 5 inexpensive tool principally for use by mechanics such as for instance cabinetmakers, carpenters, painters, floor scrapers or the like, which may however, also be used to good advantage in every household.

Another object of my invention is the provision of such a tool including a holder for securely, and exchangeably holding sand paper, emery cloth, wiping, waxing and sponging material or steel wool or the like material for abrading and 15 cleaning various articles or surfaces.

A further object of my invention is the provision of a tool of this character equipped with conveniently operated means for securely holding the sand paper or the like member during on the operation, while at the same time permitting a ready exchange of the operating member for a new one or one of another type.

A still further object of my invention is the provision of a tool of the above described type having a suitable operating handle allowing its ready detachment for storing and shipping purposes while strong, spring operated clamps securely clamp the ends of the sand paper or the like to the holder board carrying the handle, and suitable cushioning devices for the sand paper or the like material are provided to provide for a certain resiliency during the operation.

These and other objects and advantages of my invention will become more fully known as the ,- description thereof proceeds, and will then be ³⁵ specifically defined in the appended claim.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a top plan view of a tool constructed according to my invention.

⁴⁰ Fig. 2 is a side elevation thereof, parts being broken away to better divulge the invention.

Fig. 3 is a fragmentary side elevation of the lower edge of a tool illustrating the use of a ₄- wiper, polishing or waxing cloth.

Fig. 4 is a view similar to Figure 3, illustrating the use of steel wool or the like.

As illustrated, a board 10 or the like has its smooth bottom face covered by means of a soft 50 cloth cushioning material 11 covered by a sheet of sand paper 12, the end edges of which are folded over the end edges of the board as indicated at ί 3 and 14.

A handle 15 is held between the upper ends of 55 brackets 16, 17, the angular foot branches of which are secured to the board 10 by means of the screws 18, 19 so as to allow a ready removal of the handle for storing or shipping purposes.

Clamping frames 20, 21 preferably made of strong wire are turnably held at their inner ends g on transverse rods 22, 23 arranged in suitable supporting brackets 24, 25 pairwise arranged near the center of the board. .

Strong wire springs 26, 27 are wound between their ends about the rods 22, 23 near their ends, ₁₀and the outer, hook-shaped ends of these springs are engaging with their hook ends 26 the clamp frame from above to hold the frames in their clamping position while the inner ends of the springs are loop-shaped one within the other to 15 rest against the board 10, as shown at 24 and 25 respectively.

If desired, the sand paper may be replaced by a wiper or polishing cloth, as indicated at 27 in Figure 3, or by a supply of steel wool 28. ₂0

The use and operation of my tool will be entirely clear from the above description by simultaneous reference to the drawing, and it will be clear that I have produced a tool which may be readily used by means of its removable handle to ₂₅abrade, clean, polish and scrape articles and surfaces, and may be conveniently packed for shipping and storage while its operation will produce smooth, clean surfaces by the sand paper, emory cloth, wiping cloth or steel wool which at all _3Qtimes is held in a flat and cushioned position so as to yield somewhat in order to provide the sometimes necessary resiliency, and if steel wool is used to abrade floors, for instance may be used with a suitable long handle. The clamp frames _g5will allow a ready removal and exchange of the material used for the operation desired while in their clamping position will securely hold the material to· the board without possibility of developing undesirable wrinkles or the like.

It will be understood that I have described and shown the preferred form of my invention only as one example of the many possible ways to practically construct the same, and that I may make such changes in the general arrangement of the device and in the construction of its minor ^4δdetails without departure from the spirit of my invention and the principles involved, provided these changes remain within the scope of the appended claim.
