' BRUSH Application filed April 2, 1932. :Serial. Nb. 602,686.

This invention relates, generally, ,to brushes; andthe invention has reference, more. particularly, to a; novel brush of the type wherein the bristles are retained 'or held in place by twisted metal strands or wires, the said brush being adapted for general cleaning purposes and being especially suitalllilefor use in cleaning automobiles and-the lre.

Brushes of the type having their bristles heldin position by twisted metal strands or wires have not become very popular for automobile. use or other usesrequiring severe service because, among other reasons, of the difliculty of constructing these brushes so as to withstand rough handling and because of the difliculty of designing these brushes so that they will present a uniform and c011- tinuous bristle area of substantial size. The principal object of the present invention is to provide a novel brush employing twisted bristle carrying strands, which strands are so constructed and arranged as to provide a strong and serviceable brush having a relatively largeoperative surface with the bristles thereof disposed for effective use over the entire surface of the brush.

Another object of the present invention lies in the provision of a novel brush of the above character having bristle carrying twisted strands arranged in a pluralityxof loops, one of which loops lies in the transverse plane of the brush, whereas another of these twisted strand loops lies in a plane extending substantially at right anglesto the transverse plane of the brush, the said second loop lying within the confines of the first mentioned 'loop, the said loops being interconnected in a novel manner to provide a rigid construction of great durability.

Another object of the present invention is to provide a novel brush of the'above character which is of simple construction and which is adapted to hold a sponge therewithin as for the purpose of retaininga sufiicient quantity of water for desired application to the surfaces worked over by the brush.

Other objects of this invention, not at this time more particularly enumerated, will be loop 4 is of substantially giving the brush an external contour in plan square in shape.

shown in Fig. 2 so as to clearly understood from tailed description of the same, 7

Thei-nvention is clearly illustrated in the accompanying drawings, in which:

Fig. 1 is a view in front elevation of the novel brush of the. present invention, 1 Fig. 2 is a view in side elevation of the structure shown in Fig. 1. s 1 1 Fig. 3 is a schematic part sectional view taken substantially along line 3-3 of Fig. '2. F 1g. 41 a part sectional view taken along ef r Fig. 1; and. s V

Fig. @5 is va view similar to Fig. 1 but with parts broken away and illustrates a slightly modified form .ofconstruction.

Similar characters of referenceare employed in all of the above described views to indicate corresponding parts.

Referring now to Figs. 1 m4 of the drawings, the reference numeral l, 'designates the novel brush of this invention as a whole. Brush 1 comprises a handle 2 having a recess or cavity 3 in its upper end for receiw mg and retaining ,the twisted bristle .carr ing strands of the brush. The brush l is formed with .a transversely disposed loop 4 consisting of tWQStrands or wires .5 and-6 twisted tightly uponone another with bristles 'Z gripped therebetween. The bristles 7' are grlp-p d substantially midway. of their lengths by the tightly twisted strands 5 and 6 so thatthese bristles, as a result ofthe twist of the strands, arecaused to extend outwardly in all directions from these. twisted strands. The free ends of the loop 4 are pressed toward each other and project into the cavity 3 of the handle .2 andarefirmly cemented therein 53S by a suitable cement or oomposltion 8. The transversely disposed oval shape, thereby wh ch is alsosubstantially oval as is illustrated in Fig. l. Itis to be understood, how,-

ever, that the loop 4: may have shapes other than .oval, for instance, this loop may be The loop 1 is preferably inchned rearwardly somewhat as especially better present its working face for use.

At the upper center of the loop or the the following d sisting of twisted bristle carrying strands or wires '13 and 14 is positioned within the confines of loop 4 and lies in a plane extending substantially at right angles to the plane of comparison with its length and has the shape especially shown in Fig. 4. The lower free ends of this loop 12 are fixed in the recess 3 of handle 2. The two wires 13 and 14 at the upper end or bight of the loop 12 grip the ringlet 11 therebetween to thereby secure the upper end of this loopto this ringlet. The bristles 7 carried by theloop 12 project outwardly in all directions from the wiresvof this loop, thereby fillingup the space within the center of loopv 4 and giving the brush a substantial and solid central portion, sothat the bristles of thebrush continue across the entire face thereof, as especially shown in Fig.1."

1 In order that the brush may hold-a desired quantity of water in use, the same is illustrated in Figs. 1 and 4 as provided with a sponge or otherabsorbent body 15 that is positioned within the loop 12. Sponge 15 is held by a doubled over and twisted strand of wire 16, the upper end of which is looped through the ringlet 11 and the lower end of which is embedded'in the cement 8 within cavity '3 of handle 2. With the sponge 15 included in the brush 1, the same will pick up 'and hold a desired quantity of water or washingliquid in use and will supply this liquid in regulated quantity to the surface being washed. W I V Owing to the practical continuity of the bristle surfaceextending completely. across the face of the brush at both the front and back thereof, the brush is very effective in removing dirt. Also, thebristles' of the two loops 4 and :12 mutually support one another andthereby prevent the undue flattening or distortion of' these bristles in use. The simple expedient of using ringlets 10 and 11 serves to securely connect the two loops 4 and 12 together at their upperends, whereas their lower ends are' held firmly together within the cavity of handle 2. The mutual repulsion of those portions of the bristles 7 and7, which lie within the interior of the brush, together with the natural tendency of the twisted metal strandsof loops 4and 12, 'owing to their resiliency, to expand these loops, serve'to-urge the loops outwardlyl'into desired position, thereby greatly enhancing the rigidity of the brush. It will be'noted that transverse loop 4gives the brush great strength in a transverse direction while the loop 12 gives the brush its strength in a direction at right angles to loop 4. The presence of the sponge carrying wire 16 also enhances the strength of the brush.

It will be apparent that for some uses the sponge 15 will be unnecessary and therefor this sponge together with its twisted carrying strand 16' may be omitted on occasions, as illustrated in Fig. 5. The remaining parts of the structure of Fig. 5 are identical .with those of the preceding figures. In the loop '4. The loop 12 is relativelynarrow in fforn'rof the invention illustrated in Figs. 1 to 4, wherein the sponge 15 is used, the wires 13 and 14 of the loop 12 are preferably made of smaller diameter than the wires of loop 8, and henceloop 12 will not be as stiff as loop 4, whereby loop 12 will be more or less flexible in use so that when pressure is applied to bristles 7 ,such'pressure will deflect loop 12 sufficiently to effect the desired compression of sponge 15, so that liquid held by this sponge 'willbe readily discharged therefrom and onto the surface being cleaned.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing-from the scope thereof, as defined by the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. 7
