A FIRE GOMPOSEDQOF JOHNATHAN JENKS R.

PHILADELPHIA, PENNSYLVANIA.

Application filed September My invention relates to a new and useful construction in brushes and the like, and :it

' relates more particularly to-a jnovel preformed metallic tuft or head plate, having 5 suitableflcavitie'sor sockets therein for the reception of the individualutuft of hairor bristles, and upon which a series of tufts may be permanently assembled, and whereby said assembled tufts may thenbe attached .to a handle, head or stockof wood or the like.

My invention relates more particularly; to

the typeof brushes in'which aseriesf of tufts of hair or bristles are assembled in rows, upon a suitable'head or stock, and in whichjit has been the practice heretofore, to form individual tufts ofhairor bristles by wrapping wire around the roots of-,the-bristles, and tying them thus into tufts, then encasing or dipping the roots of the tuftina suitable plastic or liquid cement,such as. pitch, glue, or rubber,

and thento secure the, individual tuft of his tleseto a Wooden head or. stock,by mean'siof fastening devices extending through the tufts longitudinally, between the rows of tufts, and

extending'upwardly into the head or stock,

In this prior art constructiomthe wire, wrapping around eachindividual tuft was thus exposed, and after a reasonableamount of use, one or more of the wrapping wires would wear through or-break, with the result that thetuftof bristles would be unbound andwouldfall out, 1 l The object of my'invention isto eliminate the breaking of the binders of the tufts, and thus to increase'the life of the brush considerably, by providing a preformed and integral head plate of metal havingtherein suitable tuft receiving sockets, into'which the individual tufts may be inserted. and within .Whichthey may be secured, so as to form a complete tuft assembly upon said plate, and thereafter to secure the tuft assemblyupon the. plate, to a suitablewooden heador stock, by one or several fastening. means such as screws or the like.

Another object of my invention is to eliminate the labor and time consumed in wrapping the tufts of bristles with the usual wire binder, at the roots thereof and thus greatly to reduce the cost of manufacture of brushes of this character. 3

For the purpose of illustrating my invention I have shown in the accompanying drawings preferred embodiments thereof which are at present preferred by mesince they will BRUSH,

.Figure5 represents a fragmentary. side clef. vation of the m Referring to the drawings, in which like reference characters indicate like parts, 1 des} etallic head plate of my inven-- so i ignates the wooden head or stock of thebrush,

having provided therein, a slightly inclined handle socket 2, of the usual construction, and to theflower surface 3 of which, the brush or'tuft assembly 4 is adaptedto be'secured, as shown particularly in. Figures 1,;2and 3. e ,lThe pre-formed -.int egr al metallic .head

. plate or tuft plate 5, is'shown particularlyin Figures 4, 5 and 6, and comprises an integrally cast, jdie-cast, stamped or otherwise formed metallic member of the same general shapeas the lower surface 3 of the wooden brush head 1', and is provided ,witha series of upwardly extending tuft receiving sockets 6 on one lon gitudinal side of the plate, and a similar series' of tuft receiving sockets 7, along the opposed longitudinalsideof the plate, as well as the two transverse terminalsocketsS and 9. A

.rib '10 is provided intermediate *the two opposed rows of sockets ,6. and} 7, extending lonjgitudinally of the platerand formed integrally therewith along a medianline between the two terminal sockets 8 and 9,. The rib 10 may be of any suitable crosssection, such as a channel cross section illustrated particularly in Figures l. and 6. Thus each of the longitudinal sockets 6' and? is formed by one of'thesemi-circularouter or scallop shapedwalls 11, which join with the upright longitudinal walls 12, of the channel 10. The vertical walls 13 of theterminal sockets 8 and 9, are

7 suitable amount.

In carryin out my invention, I take suit able tufts of hair, bristles or the like, of any desired-size or length, with their ends aligned with each-other, and insert the roots thereof snugly into the sockets 6 and 7, as well as the terminal'sockets 8 and 9, in the manner shown particularly in Figures 2 and 3, completely fillin said sockets with bristles. With the sockets thus filled with bristles, in the manner shown particularly in Figures 2 and 3, the-socket plate 5 is then-dipped into a suitable cement, preferably a rubber cement or latex rubber, so as to impregnate the bases of the bristles and to fill the interstices between the roots ofthe bristles and the walls of the tuft sockets, with such binder or cement 16, in a manner shown in Figures 2 and 3, in which figures it will be seen that the bases or roots of the bristles 14 are encased and enclosed within a rubber filler or hinder- 16, which completely surrounds the roots and fills the spaces between the successive roots of the bristles as well as the spaces between the bristles and the metallic walls 11 and 13 of the tuft sockets 6, 7,8 and 93 After thus impregnating the roots of the tufts of bristles, with a rubber binding cement, the binder of rubber is then vulcanized in the usual manner by the application of heat theretoand with the use of appropriate accelerator. By this means a tuft assembly is produced upon the metallic plate 5, which is complete and which may then be applied to any suitable head or handle, as may be desired.

For the purpose of securing the tuft assembly or brush assembly 4 to a suitable handle or head 1, a series of suitable apertures 17 and 18 are provided in the upper wall 19 of thelongitudinal rib 10 of the tuft plate 5. The brush assembly 4 is then positioned against the lower surface 3 of any suitable wooden head or stock 1, and a pair of Wood screws 20 are passed through the apertures 17 into the stock 1 and secured tightly. If desired, a series of machine screws 21 may be passed through suitable apertures 22 in the wooden stock or red, and

threaded into the apertures 18, which have previously been providedwith properinternalthreads. By this means the entire brush assembly is, drawn up tightly, against the lower surface? of the wooden head stock 1, thus completing. the brush, 7

It will now be apparent that I have devised a novel and useful construction of brush andmethod of making same which embodies the features of advantage enumerated as desirable inthestatement of the invention and the above description and while I have in the present instanceshown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understoodthat the same is susceptible of modification in various partieularswithout departing from the spirit or scope-of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is a 1. In a device of the character stated, the combination of an integral socket plate having a longitudinal central channel therein, a plurality of rows of intermediate tuft receiving sockets extending longitudinally of said plate on either side of said channel, transverse end sockets of greater width and having walls of greater height than those of said intermediate sockets, tufts of bristles seated in all ofsaid sockets and adhesively secured therein, and a cement filling the interstices between the roots of said bristles, said longitudinal channel of said socket plate being adapted for the reception of fastening devices to secure said plate to ahandle.

2. Ina device of the character stated, a

brush handle, an integral socket plate having a longitudinal channel therein, detachably secured thereto and having a plurality of rows of intermediate tuft receiving sockets 0 en at their tops and bottoms and extending longitudinally thereof on each side of said channel, end sockets of greater width than said intermediate sockets, tufts of bristles seated in all of said sockets and adhesively secured therein, a cement filling the interstices between the roots of said bristles and WILLIAM REESE.
