Application filed May 9, 1912. Serial No. 696,093.

To all whom it may concern Be it known that l, Tnnonoan WOLF, a citizen of the United States, residing at Chicago, in the county of Cool; and Etate of Illinois, have invented certain new and useful Improvements in Scrapers and Polishers, of which the following is a specifics tion.

This invention relates to devices for ho d ing'an abrasive or polishing material, for example, as fibrous iterial, of any for cleaning, sci

ing or polishing.

The principal object ofitlie lllVGi'ltlQi'i to provide an improved, simple and in pensive device of this class, which will bi fective and eflicient in operation. For the attainment of these ends and the accomplishment of other new and i'iseful objects, as will appear, the invention con sists in the features of novelty in tl struction, combination and ari'a the several parts generally show. drawing and described in the sp but more particularly pointed out in ollct pended claims.

In the drawing Figure 1 is a cross seer tional view a device of this class, con-- structed in accordance with the principles of my invention; Fig. 2 is a view of the bottom of one of these devices, with the fibrous material omitted; Fig. 3 is a modified form of gripping plate which may be Isecured to the holder or block; Fig. 4 is a TlfiW looking at the bottom of a modified form of holder, part of the fibrous mate rial being removed for cleai'ness and part of" the said material being retained in position in the recess of the block; Fig. 5 is a view of ablock with triangular notches and removable hooks.

In cleaning, scraping or polishing a surface, and particularly in performing this operation upon some surfaces, itis customar to form a pad of the cleaning or polishing material, to grasp the same in the hand, and to apply it with pressure to the surface as desired. The material so employed frequently is of such a nature as to injure the hand when pressure is applied, and tlieconstant pressure and rubbing may seriously injure the-hand. Particularly is this "true when the scraping or polishing material the like. llurthermore, when pressure is sp plied to a small surface it is necessary to use the tips of the fingers, and itis not only difficult to retain the material in this position, but also is injurious to the end of thefiiigers. This invention contemplates the provisioi of a holder for such material which may be firmly grasped in the hand of an operator and pressure applied to a large or small area as desired.

Referring now more particularly to the drawing, a block 5 of any suitable material, such, for example, as wood or the like, is formed with a rounded top portion 6 and an extendingportion 7 integral therewith, and preferably slightly larger in diameter than the rounded portion 6. This rounded portion (3 is also preferably circular in form, and of a diameter to be grasped by the hand of an operator, so that the rounded portion of the block constitutes a hand-hold there for. The extending portion 7 is formed with a recess 8 which leaves a rim 9 at the outer-edge of the extending portion 7. This I or rim portion is formed with notches ill, in the surface thereof, extending through or partially through the rim and constitut ing additional means for retaining the abrasive material.

Disposed within recess 8 is a plate 11 of any desired or suitable material, but preferably formed of metallic substance and suit- .lile in shape to be contained within the re cess. This plate is provided with a plurality of projections or hooks 1'2, and in the excmplilication of the invention the hooks are formed by slitting the plate to form a tongue of metal, which is bent outwardly from the plate on one side thereof until it forms the book 12. These hooks are preferably bent in different directions, so that the hooks will engage fibrous material in any direction of motion. This plate 11 may be secured to the block 5 in any desired or suitable manner, as, for example, by means of a screw 13 and the hooks 12 do not extend from the face of the plate a sufficient distance to extend beyond the rim or edge 9 of the block 5. Fibrous material 14 of any desired or suitable kind is disposed in the recess and held therein hygtl e engagement of the hooks 12 with the material, and it will be evident that since the hooks are disposed or bent in all directions, that the "matQI'lal will be engaged thereby no matter what is the direction or movement of the clock with respect to the fibrous material.

V or a difierent no gage the other fibrous This fibrous material?! which is positively held by the engaiing books 12 may be employed to effect t of a surface or a separate pa 5 of the some material may be which is positioned below the scraper so that the fi I engage therewithand hold-the material 15 in position, the material in position when the pressure is applied to the .hloch 5 by the notched edges 9 of the block. With this construction it is ossible to polish or scrape as large or'as sma l a surem 10 ed hol cler m to the device itsel' a small surface being treated by ti ping the block upwardly upon one edge, w ereu on the material, as 15, will be engaged and old by the notches in the edge without danger of displacing the material with respect thereto.

If desired, a plate 16, similar to that shown in Fig. 3, may be employed with the same block 5, and in be noted that a plurality of arms 17 extend at from a central perforated portion 18, having hoolrs 19, difierently disposed with're spect to each other u on each arm and with still other hooks 26 a jacent the central portion ldthereof. Various other designs may on be employed, but their function is the same, via, to hold the abrasive material in poaition in the recess of the'block.

Another modification is shown in Fi d,

in which the abrasive or fibrous materia 14 so is first disposed in the recess 8 of the memher, and a looped wire or retaining member 21 18 positioned over the material the inner ends of the loop being disposed adjacent the center of the recess at which point a plate 22 4c is provided with a, fastening device or a screw 13 which is adapted to hold the looped" wire 21 and the fibrous tion in the'recess. The projects through the loops sufliciently -to enmaterial on" the out:

side thereof, whereby it is positively held and the surface may be cleaned with the other described construction.

in. using this device it is contemplated that any desired or suitable material may be used for the abrasive or polishin element, such, for example, as material rnown as mineral wool or steel wool, formed of time steel shavings, also the material which fills the recess and the same material or the pad only may be comgos'ed of the polishing or cleaning substance.

y having the pad 15 separate from the pad 14, diflerent pads may be employed and placed in the same position as the pad 15,

without changing engaged by books '12. It will be observed that the bent books 12 do not extend below the edge of the rim 9, so that even if the maaa-terial contained in the recess becomes worn material 14 in posie polishin and scraping brous material 14 will 15 being also held tapered from the inside and may extend forces desired limited only by the size of.

this construction it will fibrous nuiterial 14 I pad 15 may be of-the the material positively or is remored or drops out, thesurfacewhich is being polished or cleaned will not be en aged by the hooks. I

If esir'ed, the notches in the rim may be formed as shown at 23 in Fig. 5, in which will be seen that they triangular in shape and beveled inde th, being of great est depthon the outsi e and tapering inwardly. It is obvious that they may be through or only partiall through the rim. Instead of a toothed plate double pointed hooks 24; and single pointed books 25 may be inserted in the recess of the block by screwing them into the block or otherwise fastening them in position. Pressure may be applied either to the whole block or to any portion oi the periphcry thereof, the notched edges being adapted to hold the polishing material under the. block while pressure is applied to any part thereof,'so that a large or small surface may treated. a v a j While I have thus dwcribed the preferred embodiment of my invention, it is evident that others may make various changes in the construction, combination and arrangement of the several parts without departing from the spirit and scope of the invention.
