APPLICATION FILED MAY 17, 1913. 1,128,667. Patented Feb. 16, 1915.




citizen of the-United States, and a resident ofOak Park, in the county of Cook and State of Illinois. have.- invented certain new and useful Improvements in Brushes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had .to the accompanying drawings ..and to theletters of reference specification.

-'.lh1s invention relates to that class of toilet-or hand brushes in which the brush body or bristle-holding part or member of the brush is made of metaland consists of a plurality of connected bars severally carr ving' the tufts of bristles and having between them slots or openings adapted to facilitate the cleansing of the bristles by water or otherwise.

The object of the present invention is to improve the construction of brushes of the kind referred to in several particulars, as will hereinafter appear, and it includes iinprovements in the structured the bristleholding member itself and the means for connecting the bristles therewith, and also improvements in the construction of brushes of that kind in which the brush includes a brush-back and a. bristle-holding member made as a part separate from, and adapted for detachable connection with, such brushback.

The. invention consists in the matters hereinafter described and more particularly pointed out in the appended claims.

Inthe accompanying drawings illustrating my invention Figure 1 is aside view of ahair or like brush constructed in accordance \vith'iny invention; Fig. 2 is a top plan view thereof; Fig. 3 is a top plan view of the bristle holder removed from the brush back Fig. l is an enlarged transverse sectional view taken on the curved line of -Fig'. 2; Fig. 5 is an enlarged fragmentary detail sectional view taken on line 5 5 of Fig. "2, illustrating the springcohtr ll d locking device for detachably connecting I the bristle holder w th the brush back; Fig.

6 is an enlarged detail viev;..-of a sectionof the bristle-holding member, showing the manner in which the'bristle-holding nipples are secured to the bristle-holding member,

.and the bristle-holding wire holding a tuft or bundle of bristles in each of said nip- Specification of Letters Patent; Patnfed Feb, 16, 1915. Application filed May 17, 1913. semi n. 768,206.

pies; F ig, 7 is a vertical sectional view taken on line 77 of Fig. 6;'Fig. 8 is a transverse section taken on line 88. of F ig. '7; Fig. 9 is an cnlargedfragmentary top planvi'ew' of the bristle-holding member, showing the grooves orchannels in the rear surfaoeof' the bristle-holding member, and the. wires resting in said grooves; and Fig. 10 .is a top planvieu of a brush in which the bristleholding member constitutes in itself the back of the brush. r

The brush, shown in the accompanying drawings as embodying my invention,-comprises a back or body 1, a handle 2 connect ed with and extending from said back 1, and a bristle-holding member '3re1novably secured to the front side of said brush back bysuitable means to be. hereinafter descr'bed.

.he brush back 1, as well as the bristleholding member 3, are made of sheet metal by a swaging or stamping operation. -Both the brush-back 1 and bristle-holding mem' her 3 are transversely curved in' form and have like curvature. Each of said parts is provided with a plurality'of slots indicated, by 4 in the ease of the brush back 1. and by 5 in the case of the bristle-holding member 3. The slots 5 in tbe'hristleholding-member 3 correspond in forum and S'l'IiE with the slots at in the brush rack 1 and thc slots" in the two parts register with each other when the bristle-holding member is secured to the brushback By reason of the slotted construction described in the bristle-holding member 3, the latter consists, in effect, of. a. series of parallel bars 6, 6, connected with each other at their ends by integral parts of the said bristle-holdii'xg 3 member. Each of said bars (3 is provided with a plurality of longitudinally spaced tubular studs or nipples 7, T, in which are severally inserted orsecnred the bunches or tufts 8, 8 of bristles.

In the specific construction shown iii the drawings, the slots '4 in the brush baek l, and also the slots 5 in the bristle-holding member 3 extend transversely of these parts, as shown, and the bars ii are connected at their inner ends with 1ongitudinal.;niargina members or strips 9. 9. also preferably provided with bristle-l-ioldin; nipplesf, T carrying bunches of bristles -ln order to provide means tor -1e menia connecting the bristle-holding memb'erf as anew-s The lateral or :longitudimil, margins of; the sheet brush aback lxare provided with flanges formed by bending thejsheet metal body of said back shaped-to constitute inwardly facing. grooves or channels, adapted to receive the.

The nipples are perma nently' secured in place by expanding or riveting the ends of said reduced parts v against the inner faces of the-bars or strips.

In order that the shoulder 23 of the nipples may seat itself firmly on the outer surface. of the convex rib 20, the latter is countersunk at the convex side of the rib 20 in such 1 a'manner as'to form an annular, fiat seat for said shoulder'23.

The Teduced part 22 of each nipple 7, T is provided with an axially arranged aperture or hole 26 much smaller as follows: Each bundle orjtu'ft jof bristles is folded upon-itself to form a' looped end, and such looped end ,-i s' ins erte d' i to said "recess 25 .Each bunch or of bristles I indiameter ;than' the recess 25, and extend- V j ingthroug-hfhe sa-id reduced part-22 into the said recess 25S The bundles or tufts 8, 8 of bristles are. secured in .saidfiii'pples 7, 7,

Said aperture; 26 large enough in diameter to permit the passage of "the two looped parts ofthe wire" 27 through the same, but 'is materially smaller in diameter .than said recess "25, so that the looped end of the. bundle or tnft S of bristleswill be drawn by the wire 'inst the bottomofthe recess, but cannot rawn into said passage.

In order that the wire27 1nayproperly rest in the grooves 19, and-to prevent the wire from projecting outside ofaiid grooves when the wire passes over the inner ends of the nipple, as it entersand leaves the aperture 26, the expanded inner end of each nipple is provided with ,two opposite notches 28 in which said wire {Yr'ests' Said notches 28 may be formed by providing a V-shaped edge on the riveting toolus'ed to spread or upset the inner ends is of said nipples.

In Fig. 10 of the drawings, a brush in whichvthe back employed in the brush shown in the preceding figures is omitted and a bristle-holding member 30. made like that heretofore described,in itself constitutes theback or body of the brush, and is provided with a handle 31 directly secured thereto. 'As shown inlsaid Fig. -10

I have shown I her from the brushjback. F u'rthermore. the. mak ng of the brush back'l of'slotted form the handle 31 is made of. sheet metal and is hollow in construction and is secured to the bristle-holding member 30 by means. of

' rivets 32 inserted through'the handle 31 and a tongue 33 in the inner end of the bristle holding member which. extends int o the adjacent end of said hollow handle 31. The bristle-holding 'member 30, except for its tongue 33, the bristle-holding member 3 hereinbefore described and the corresponding parts are indicated by similar reference characters.

It is to be understood that the details of construction in the brush illustrated may be changed or variously modified without departure from the spirit of my invention,

and I do not w sh to be limited to the exact.

details of construction and arrangements shown, exceptas pointed out in the appended claims.
