UNITED STATES PATENT OFFICE.
WALTERL. REIN ANDCHARLES G. REIN, 0F CHICAGO, ILLINOIS.
POLISHING BRUSH.
Application led January 23, 1928. Serial No. 248,808.
Our invention relates to polishing brushes, and more particularly to such brushes as are power-operated, and it is our main object to provide a brush of this kind` which is easily removable from the power element after it has become clogged.
A further object of the invention is to provide a peculiar construction whereby the elements ofthe novel brush may easily come apart for the cleaning thereof.
A still further object of the invention is to construct the base or holder of the novel brush on novel lines, whereby to avoid difq iiculty in mounting or removing the holder from the power element.
A final, but nevertheless important object of the invention is to design the novel brush on lines of utmost simplicity, in order that the same may be "easily handled and inex pensively produced.
With the above objects in view and any others that may suggest themselves from the specification and claims to follow, a better understanding of the invention may be gained by reference to the accompanying drawing, in which- Figure 1 is a longitudinal sectionthrough the brush;
Fig. 2 is a perspective view of its holder; and
Fig. 3 is an end view of the brush taken from the left-hand side of Figure 1.
Polishing brushes of the type we have in mind are usually fitted upon the shaft orAv spindle of a portable power device, such as an electric drill, motor or the like. In the usual practice, the operative end of the power shaft is suitably formed to receive the brush, and the latter is then firmly secured to the shaft by nuts, washers, and other means conducive to fixing the brush both tightly and non-rotatably relative to the shaft or spindle. This method of mounting the brush has two serious disadvantages, namely, 1: that the sections of the brush, which are disks of soft cloth, are so tightly packed that they lose their gentle and flexible value as against the surface to be polished, and 2: that considerable difficulty is had in removing the brush after it has become clogged with the cleaning compound, such as Wax or similar substance having a sticky or semisolid consistency when in the form of a residue or coating on the brush sections. It has therefore been our intention to eliminate these deficiencies and carry out the above mentioned objects to their fullest extent.
Referring specifically to the drawing, 5 denotes the operative end of the shaft or spindle projecting from a power device of the type previously mentioned. Our invention requires no changes whatever `in the power device, but necessitates the cutting of the end of the shaft with a diametrically` directed slot 6 and the perforating ofthe same at an intermediate point with a cross bore 7, these being the only changes re-` uired.
The holder for the novel brush comprises mainly an arch-shaped wire 8 of medium gauge, such as No. 10 B & S wire, the cross bar 8a of the arch seating in the slot 6. The legs of the arch extend parallel to the shaft 5 on opposite sides, and pass through perforations 9 in a disk 1() mounted loosely on the shaft through the agency of a medial aperture 11. The disk is positioned just back of the cross bore 7, and is checked from motion in a forward direction by the insertion of a Cotter or other pin 12 through the said cross bore. The legs of the arch 8 emerge from the back side of the disk in the form of terminal transverse bends 13. The brush 14 consists of a mass of soft cloth disks,preferably of circular contour, the disks being centrally apertured to be strung on the shaft 5. As noted in Figure 1, the disks are also perforated on opposite sides of their central aperture to be strung on the legs ofthe arch 8 to assume the positionshown. The frontal portion of the brush is gathered as indicated at 15 and the outermost sections sewed closed as indicated at 15aL or otherwise' gathered permanently sov as to fully enclose and jacket the end of the shaft. Since the brush has a rapid rotary motion and is applied to surfaces requiring a high polish, the gathered portions 15 of the brush will shield such surfaces from contact by any metallic portion of the brush, thus protecting the surfaces from becoming marred or otherwise injured. f
In making up the brush, the arch 8 is provided With the ends 13 unbent, so that the sections of the brush 14 may be strung upon the arch and gathered as indicated at 15. The ends 13 are then bent outside the disk 10 to retain the same upon the legs of the arch. The shaft 5 is then inserted through the disk 10 and advanced until its slot 6 rellO ceives the cross bar 8a of the arch. The soft mass of brush sections is now contracted toward the outer end of the structure to momentarily expose the cross bore 7, so that the pin 12 may be inserted and spread to become locked to the shaft. It will now be seen that the metallic holder of the brush comprises a substantially rigid frame which is nonrotatably fixed upon the shaft, yet easily slid off the same in a forward direction by the simple removal of the pin 12. This removal may be effected by again compressing the brush in an outward direction to expose the pin.`
In the use of the brush, the fact that its every section is anchored to the frame-like arch 8 causes the brush to fully operate in connection with the shaft. Thus, no element of the brush can slip by reason of lost motion or an insecure fastening. Yet, the brush retains its free semi-loosc consistency, so that its action upon the surface polished is soft and gentle. In the event that the brush has become clogged with solid and soiled remnants or residue of the cleaning compound, it may be easily removed from the shaft by the simple expedient just mentioned, and a brush on another holder applied to the shaft, so that the work of cleaning is but momentarily interrupted. The discarded brush is cast aside until it is ready to be cleaned, at which time it may be easily removed from the arch by the unbending of the ends 13 of the arch legs, in which eventthe body of sections may easily be run ofi" the arch legs. In case the arch becomes deformed during the brush removing process, it may be discarded without any appreciable loss, since it is but a length of ordinary iron wire, which is trifling in cost. It is customary to boil a brushr of this kind in water or a suitable solution to loosen the cleaning compound deposits from it; and this may be done by immersing the brush even while on the wire holder, since the brush sections are sufficiently loose on the latter to be reached and cleaned by the boiling water or solution.
In conclusion, it will be evident that we have provided a brush which supplies to the power feature the advantages yof the soft polishing cloth ordinarily used by hand. lThe novel brush is both in' the proper condition for the work required of it and in fixed relation to the power element, so that no annoyance is experienced by the operator during its use.
While we have illustrated and described our invention in the vpreferred form, it will be evident that the same is capable of many minor changes and refinements, and it is our intention to claim such changes and refinements as coming within the spirit and scope of the appended claims.
We claim 1. A power brush comprising a shaft formed with a terminal recess, an arch with its cap seated in the recess and legs in spaced relation alongs'idethe shaft, and a brush body impaled on the shaft and arch legs.
2.' A power brush comprising a shaft formed with a terminal recess, an arch with its capI seated in the recess and legs in spaced relation alongside the shaft, and a laminated brush body impaled on the shaft and arch legs, the laminations opposite the-said cap being gathered and fastened to embed said cap and the terminal portion of the shaft.
3. A power brush comprising a shaft having a perforation at an intermediate point, an arch non-rotatably applied at the forward end of the shaft and having its legs extending alongside the shaft from said end, a plate mounted on the shaft back of said perforation, the plate being perforated to receive said legs, a stop for the plate secured in said perforation, bends formed from said legs on the back of said plate, and a brush body mounted on the shaftv and the legs between the plate and said end.
4. A power brush comprising a shaft perforated at an intermediate point, an arch non-rotatably appliedat the forward end of the shaft and having its legs extending alongside the shaft from said end, a plate mounted on the shaft back of said perforation, the plate being apertured to receive said legs, a stop pin for the plate secured in said perforation, bends formed fromvsaid legson thebaclr of said plate, and a brush body mounted on the shaft and the legs between theplate 'and said end.
5. A power brush comprising a shaftnicked in the forward end-and perforated at an intermediate point, an arch-rod seated with its cap in said nick and havingV its legs extending iny parallelism alongside the shaft from said end, a plate mounted on the shaft back of said perforation, the plate being apertured to receive said legs, a stop pin for the plate secured in said perforation, bends formed from said legs on the back of said plate, and a brush body mounted on the shaft and the legs between the plate and said end.
