l narran srArss WILLIAM SEVERNS. OF CHICAGO, ILLINOIS.

SEB AND POLISHER.

Application led June 27, 1921. Serial No. 4840,569.

To all whom t may concern:

Be it known that I, WILLIAM SEvEnNs, a citizen of the United States, and a resident of the city of Chicago, in the .county of Cook and State of Illinois, have invented certain new and useful Improvements in a Sander and Polisher; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this speciication.

This invention relates to improvements in Sanders and polishers for oors or the like and has for one of its objects the provision of such an apparatus which can be readily manipulated and to which the polishing means or sanding means such as a cloth, sand paper, or the like, may be applied, and on which said surfacing means will be very securely held in position.

An objrct of this invention is the provision of a sander and polisher which is adapted to be pushed about on a ioor by means of a handle fitted thereinto by a exibly mounted socket and which sander shall have suiiicient weight so that any undue pressure thereon is not required.

A further important object of this invention is the provision of a sander or polisher having means thereon adapted to securely clamp and hold in position any polishing or abrasive means and which shall so hold the sanding or polishing means that it will be impossible for the same to work loose while in use.

A still further important object of the invention is the provision of a sanding and polishing means provided with a tensioned clamping means which is' adjustable.

Still another important object of the invention is the p-rovision of a sanding and polishing apparatus provided with a clamping means consisting of a spring plate or the like cooperating with the base of the holder in such a manner as to securely hold any thickness of sanding or polishing means thereon no matter in what position. and to hold the same without any danger of its becomin loose during use.

`Other an further important objects of this invention will be apparent from the disclosures in the accompanying drawings and following specification.

The invention (in. a preferred form) is illustrated in thc drawings and hereinafter more fully described.

0n the drawings:

Figure l is a top plan View of the improved polishing and sanding apparatus, with the handle removed therefrom.

Figure 2 is a section taken on the line 2 2 of Figure 1 looking in the direction indicated by the arrows.

Figure 3 is a section taken approximately on the line 3 3 of Figure 1.

Figure 4 is a sectional view' showing the apparatus before the tensioning means has been adjusted to .holding position.

Figure 5 is a side elevation of the sander and polisher assembled and with the handle applied thereto.

As shown on the drawings The apparatus comprises a base 10 of any hard and heavy material such as a suitable metal of a desired thickness and having an npstanding flange 12 therearound encircling all the sides thereof. This base 10 is preferably of a rectangular form as shown. Adapted to cooperate with the base by means of an attachment to an upwardly extending integral lug 14 in the middle thereof is a socket member 1G pivoted thereto by means of a bolt or rivet 18 passing through a hole in the lug 14 and this socket 16 is adapted to be swung about said pivot for the accommodation and manipulation of a handle 20 which is provided with screw threads or other means on the end thereof for suitable cooperation with the socket 16. Fitted in the bottom of the base 10' and having their heads 24 set in depressions therein are the upwardly extending threaded bolts 22 provided with lock nuts 26 coacting with the upper face of the base 10'to hold the bolts in position. These bolts 22 are provided with screw threads and have winged nuts 28 mounted thereon adapted to cooperate with and hold in position a exible spring plate 30 formed preferably in the shape of a circular arc as shown in Figures 3 and 4 and made of such material that it may be subjected to tension. The edges of this arc-sha ed tension member or plate 30 areA straig t and adapted to contact with the top of the base 10, or with/the inner face of the anges 12 on two opposite sides thereof near the junction of these faces and aber? the top. This junction forms the interior of an angle which acts like a groove to cooperate with the edge of the sprin and cause the covering 32 to be tighten upon turnin down the nuts 28. This covering 32 which is of sand paper, polishing cloth or the like is thus securely held in position.

The o eration is as follows:

The p ate member 30 is lifted from the base 10 by unscrewing the winged nuts 28 on the bolts 22 and then a piece of polishing cloth, sand paper, or the like, as shown at 32, is placed in posit-ion upon the base passing thereunder and with its ends overlapping the upper edges of the upwardly extending flange 12 on two sides of the apparatus. The plate 30 is then placed in position as shown in Figure 4 with the polishing cloth or sand paper 32 drawn as tightly as possible. After this the win ed nuts 28 are tightened, thereby tensioning the plate 30 and causing its straight sides or edges to push the Vpolishing member or sand pa er 32 very closely into the angles formed etween the base 10 and its upstanding anges 12 as shown in Figure 3, securely holding the same in position and affording a very accurate contact between the bottom of the base. 10 and the polisher 32. The apparatus is then ready for use and can be used in connection lwith almost any material to be polished, as ioors, furniture or the like, the size of the polisher. being of course variable to suit the particular requirements. lIts weight is such that no undue pressure will be needed to polish a :floor or the like, the pressure necessary to push the body over the surface of the article being polished usually being found entirely suicient.

It will be evident that the polishin member or cloth 32 may be readily canged whenever desired and with a mmimum of' time and inconvenience and that when laced in position it will be very securely lield and cannot become loose through the operation of the polisher.

Leoni It willfurther be evident that when this device is used as a polishing means with a polishing cloth or the like 32 u on the bottom thereof, a quantity of liqui polish may be placed in the base or a suitable container therein and allowed to penetrate to the polishing1 cloth 32 through the openings around t e bolts 22 or other small o enings which may be made through the ase 10 if desired.

The shape of the polisher may bevaried as desired, a triangular, circular or other form of base being readily adaptable to the invention. The winged nuts may further be substituted by any suitable clamping means, and the bolts coactin therewith may be made integral with the ase if preferred.

I am aware that man changes may be made and various detai s of construction varied without departin from the principles of this invention, .an I therefore do not purpose limiting the patent granted thereon otherwise than necessitated by the prior art.

I claim as my invention:

A floor polishing device, com rising a base formed with an upstanding ange and a central inte al lug, an arc-sha ed spring plate, threaded bolts fixed to said base and at their up er ends assing through apertures in sai spring p ate, wing nuts on Said bolts adapted to engage the up r surfaces of said spring plate to flatten t e same and to grip a finishing material between the plate ed es and the inner facesbf the flange on said ase, and a handle-receiving socket pivoted to the central lu projecting freely throug said spring plate.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.

LIAM SEVERNS.
