' ATTORNEYS Patented Dec. 18, 1934 UNITED STATES PATENT OFF-ICE Application February 7, 1933, Serial No. 055,549
, Renewed November 9, 1934 9 Claims.
My present invention relates more especially to power driven, manually controlled rotary surface treating implements of the character used for cleaning, polishing, scraping or abradi'ng. While the invention in certain of its broadest aspects is not necessarily limited thereto, the invention finds its preferred field of application where the active cleaning, polishing, scraping or abrading agency generically is of metal wool, preferably steel wool.
Among the objects of the invention are to provide an instrumentality for the above purpose, which precludes contact of any wool holding instrumentality with the surface to be cleaned, polished, scraped or abraded, and yet without danger of the wool slipping relative to the driving holder or coming loose therefrom.
Another object is to provide an instrumentality of the above type, of simple and inexpensive construction to which the wool is easily applied in secure operative relation without the need for any tools other than a conventional wrench.
Another object is to provide an apparatus of the above type, in which while the wool is effectively clamped, the resilience of the wool at the operative abrading or polishing surface is not impaired.
Other objects will be in part obvious and in part pointed out hereinafter.
Inthe accompanying drawing in which is shown one of various possible embodiments of the several features of the invention,
Fig. 1 shows a perspective view of the implement, partly in section,
Fig. 2 shows a dropped sectional view of the constituent elements of the head prior to assembly.
Fig. 3 is a view in longitudinal cross-section of the head completely assembled, and
Fig. 4 is a plan view of the head viewed from the interior showing the relation of the impaling pins. I
Referring now to Figs. 2 to 4 of the drawing, the operating head preferably comprises a bellshaped wool holder 10, ordinarily of aluminum, preferably formed interiorly as the segment of a sphere and provided with an integral mounting nipple 11. The metal is preferably thicker at the nipple or mounting end or base for strength and tapers 011 to a thinner rim 12. Amxed in the bell are wool impaling pins 13 of desired number, though ordinarily three such pins are sufficient. These pins are preferably screwed into the head at 14 about an inch from the mounting nipple thereof. The impaling pins, as shown,
are preferably equi-distant-and extend obliquely outward toward the rim and obliquely forward with respect to the radial planes of their mounted ends, as shown. While the particular relations are not critical. it is preferable to have the impaling pins extend outward at an angle of about 30 degrees to the vertical and to point forward at an angle of about 60 degrees relative to the radial planes of their bases. Preferably the pins are pointed, as at 15, and their shanks are roughened illustratively-by threading as at 13.
In addition to the impaling pins, the head includes a wool retainer preferably in the form of a clamp. This clamp in the preferred embodiment comprises a bolt 17, of brass'extending axially of the bell-shaped head and threaded into the base thereof as .at18. The bolt has a wide head 19 thereon provided with a socket 20 for a tightening key (not shown),
The preferred operatingmaterial to be embodied in the head described, is steel wool preformed as a generally spherical pompon 21 with an axial aperture 22 therethrough. The pompon is readily applied to the head by impaling on the pins 13 therein. This can bedo'ne by a direct thrust in which the steel wool will readily find its way over the impaling pins. Thereupon the bolt 1'7 is inserted through the aperture 22 in the wool pompon and tightened in position until, as shown in Fig. 3, its head has moved past the rim 12 of the holder. In this operation, the wool is wedged into the bell about the impaling pins and between the bolt head and the impaling pins. The axial diameter of the pompon being thus sharply compressed, the wool ball spreads laterally, as best shown in Fig. 3, outward to overlap the rim 12 of the bell, as at 23, and inwardly to overlap the head of the bolt 17, as at 24.
The steel wool installed in its head, as shown in Fig. 3, is quite effectively held. In the rapid r0,- tation of the head, the tendency is for the wool to be "forced ontorather than of! the impaling pins and the bolt head 19 wedges the wool so tightly in position that it will not accidently be- .come loose. The threads or irregularities 13 on the impaling pins contribute to the security of attachment of the wool pompon thereto.
The steel wool is so conformed that a generally flat area is provided for treating a flat surface, such as a table, while the rounded rim 23 thereof is effective for access to curved surfaces, corners or the like. The metal wool having been spread, as set forth at its operative regions, the resiliency thereof is not impaired, despite the clamping action of the bolt head 19.
It is obvious that the wool pompon can readily be replaced after it has been worn or sullied. Ordinarily, the wool pompon may be reversed by removal and inserting the opposite part into the bell and exposing for further use, the part that had originally been within the mounting bell.
The wool holding head may be associated with the power driving means in any conventional manner, one such connection being illustratively shown in Fig. 1, where a driving haft 28 is shown threaded at 27 into the nipple l1 and mounting in a socket 28 at the opposite end thereof, the flexible driving shaft 29 which may be driven from any suitable electric motor (not shown). A handle sleeve 30 is telescoped over the haft '28 and held in place thereon by a cap 31 surrounding the flexible shaft and threaded as at 32 on to the upper end of the bait.
It will thus be seen that there is herein described apparatus in which the several features of this invention are embodied, and which apparatus in this action attains the various objects of the invention and is well suited to meet the requ1rements of practical use.
As many changes could be made in the above construction, and many apparently widely dfferent embodiments of this invention could be made'without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. I
