WIRE BRUSH.
Application filed December 19, 1928. Serial No. 681,585.
To all whom it may concern:
Be it known that I, FRANS O. ALBER'rsoN, a citizen of the United States, and resident of Sioux City, in the county of Woodbury and State of Iowa, have invented a certain new and useful Improvement 7 in Wire Brushes, of which the following is a full,
clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this. specification.
My invention relates to a brush which may be utilized for removing carbon from the cylinders of internal combustion engines and for similar purposes. Generally stated, my invention contemplates the provision of a rotary wire brush which is of sturdy and simple construction and which may be economically manufactured.
A salient feature of my invention consists in arranging the abrading ends of the wires in such a manner that each of such ends supports the others against substantial bending when the brush is rotated in contact with the cylinder wall or other object under going cleaning.
Another important feature of my present invention consists in the provision of improved means for spacing and holding the several wires.
Other features, objects and advantages of my invention will appear from the following detailed description wherein reference is made to the accompanying drawing, in which- Figure 1 is an elevational view of a brush embodying my invention, this view illustrating the brush in operative relation to a flexible shaft whereby the brush may be driven Figure 2 is an axial sectional view of the brush, certain of the wire abradin g members being broken away to simplify the illustration. a 7 Figure 3 is a plan view of the abrading end of the brush;
Figure 4 is a sectional view taken on the line 44 of Figure 1, and looking in the direction indicated by the arrows; and
. Figure 5 is a view corresponding to Figure 4 and illustrating a slightly modified embodiment of my invention.
Similar characters of reference refer to similar parts throughout the several views.
The brush of my invention as illustrated in the accompanying drawings comprises a w1 re holder and support consisting of three principal parts, namely a cup-shaped metal member 6, a disc 7, and an annulus 8.
The cup-shaped member 6 conveniently, but not necessarily, in the form of a metal stamping is provided with a central aperture 9 through which freely extends the threaded end 10 of a driving stem 11, the said driving stem being also provided with an annular flange 11 which is adapted to bear agalnst the member 6 as is clearly illustrated in Figure 2.
The disc 7 is preferably of substantial thickness and has a diameter such that it will fit snugly within the flange of the cupshaped member 6. It will be noted that the disc 7. is tapped at its central portion to cooperate with the threads of the portion 10 of the'driving stem. The disc 7 is provided at its periphery with a multiplicity of equidistantly spaced radial notches 1212.
The annulus 8 has an outside diameter which is less than the'inside diameter of the flange of the cup member 6 by an amount equal to twice the diameter of the wire of which theabrading members are formed. That face of the annulus which lies adjacent the disc 7 is preferably flat, while the opposite face of the annulus is rounded so that it will not tend to shear the wires against which it is clamped when the several parts of the brush are assembled.
The abrading members of the brush are formed by a plurality of wires 14-14, each of which is bent at its central point to provide legs of substantially equal length, both legs of each of said wire members extending through one of the notches in the disc 7. It will be noted that the annulus 8 lies between the legs of each of the wire members 14 and in the bend thereof, the said annulus serving to prevent the wires from escaping from the notches 12-42 when the several parts of the brush are properly assembled. The several wire members 14, the annulus 8, and the cup-shaped member 6 are securely'clamped together between the disc 7 and the flange 11 of the driving stem when the portion 10 of the driving stem is threaded into the disc 7 to secure the several parts of the brush together.
' trated in the drawings.
It will be noted that the legs of the several Wire members extend away from the wire holder or slilipport in two circular formations of di erent diameter. I prefer to bend the wire portions of the inner formation outwardly at their free ends, and to turn the wire portions of the outer formation inwardly at their free ends, as is clearly illus- Each wire portion of each of the said formations thus crosses and lies between wire portions of the other formation. This construction is'ver desirable, because it enables each of the. a rading wire ends to support each of the adjacent ends against that bending which tends to occur when the brush is rotated while the ends of the wires-are in contact with an engine cylinder or other. surface to be cleaned. A brush having its several wire abrading members arranged in this manner tends to maintain its circular transverse cross-section even under continued use, but the extremities of its several abrading wires are nevertheless sufficiently ylelding to prevent the cylinder wall, or other hard metal surface being cleaned, from being scored or abraded to an objectionable extent.
Although the brush of my invention may be driven in any suitable manner, I prefer to operate it by securing the driving stem 11 thereof in the chuck 15 of a flexible driving member illustrated at 16.
In Figures 1 to 4, I have illustrated a construction wherein but one wire is received in each of the notches 12 of the disc 7. When the abrading members of the brush are to be formed of relatively light stock, a plurality of wires may be received in the notches as illustrated in Figure 5. Corresponding legs of each pair or group of wires extending through any one of the notches 12 are turned outwardly or inwardly (with respect to the axis'of the brushl at their free ends in exactly the same Way that the free ends of the sin 1e wires are turned inwardly and outwar 1y near their extremities, as illustrated in Figures 1 to 4 inclusive.
Having thus illustrated and described the preferred embodiment of my invention, what I claim is new and desire to secure by Letters Patent of the United States is 1. Ina brush of the class described, a pluralityof abrading wires, each bent intermediate its ends to provide two legs, a spacer consisting of a disc provided at its periphery with radial notches receiving said wires, an annulus which extends between the legs of each of said wires and lies in the bend thereof, and means for clam ing the wires to said annulus and the annu us to said disc.
notches at its periphery, both legs of each der said disc, said annulus passing between" the legs of each wire and lying in the bend thereof, and means for clamping said wires and annulus between said cup and disc.
4. In a brush of the class described, a cup-shaped member, a plurality of abrading wires each bent intermediate its end to providelegs of substantially equal length, a disc and an annulus in said on -shaped member, said disc bein provided with a plurality of radial note es, each wire extendin around said annulus and having both 0 its legs passing through one of said notches, and a driving stem comprising means for clamping said wires and annulus between the disc and cup-shaped member.
5. In a brush of the class described, a cup-shaped member, annulus and disc, the annulus and disc being disposed in the on shaped member with the disc outside of t e annulus, a plurality of abrading wires, each bent toprovide two legs of substantiall equal length, said disc. being provided wit a plurality of radial notches, both legs of each wire being disposed in one of said notches, the annulus extending between the legs of each wire and lying in the bend thereof, and means for clamping said disc, annulus, and cup together, the free end portions of each wire crossing the free end portions of other wires so that the said end portions are mutually supported.
6. rotarv wire brush comprising an annular row of cylindrically arranged abrading wires terminating ina plane at a normal to the axis of rotation, the successive wires being crossed and substantially in contact for causing rotary strain on a particular wire within its limits of elasticity to be borne by successive wires about the annular row.
7 A rotary wire brush comprising a plurality of cylindrically arranged longitudinally extending abrading wires, the outer ends of which terminate in staggered relation, and means for supporting the wires at their inner ends, the wires being crossed intermediate their ends and substantially in contact where thus crossed for distributing rotational strain on the end of any particular was over a plurality of successive wires,
8. A rotary brush comprising a support, a multiplicity of abrading wires bent intermediate their ends to form pairs of legs, and means for securing said wires to said support at their looped ends, the Wires being longitudinally disposed in cylindrical formation with the legs of each Wire crossed intermediate their free and their looped ends and all the legs terminating in a staggered 1 annular row.
In witness whereof, I hereunto subscribe 1y name this 13th dav of December, 1923. FRANS O. ALBERTSON. lVitnesses:
