of Brushes; and we do hereby declare that the j followingspecification, in connection with the accompanying drawings, affordsa full, clear,

undexact description of the same.

' `Ot' the drawingsFigure l represents an u'n-r der side view of the brush, rbrush-back, and 'stleng'thenciu Fig.2 represents alongitudinal section through the same. Fig. 3 represents a transverse section through a brush made after the herein-describedlinvention.V Fi g. 4 represents a lougitudinalsection through certain molds, by which the 'handle and back of the brush may be shaped, formed, and molded over the strengthener. Fig. 'represents a longitudinal sec-tion through 'a' modified form Yot' strengthener, and which becomes entirely incased in the handle portion ot' what is termed a brush-back, as will be explained.

Similar letters of reference, where they occur in the separate figures, denote like vparts in all of theV drawings.

This invention consists, first, in a. brushfbach composed of a bed or base suitable forhold ing a brush, a. handle, and an .extensiomp'ece or strengthener extending from one to the other, anda composition applied to both "of" such parts, and surrounding said strengthener y 'or extension-piece; and it further consists in a brush-backin which its shape, form and or-l namentation is given to it at the sa-metime und by the same means .that embeds the'.

strengthener inthe plastic composition that constitutes its exterior. The subjoined description. will, enable .any oneskilled in the art to make and practice this invention. l

A thin plate,a,o wood,metal,or other suitable material of proper strdgth and shape, is irst prepared. This a, at suchgfportons of tas may be reqnireftflr holding bristles, may be tpunched with a series of holes, in each of which a. mass of bristles, b, are inserted, so

Aas to project above as well' as below the piece a. )uth'e said piece a, which extends from the body of the bruSII-baCkinto and nearly to ot' the bristles projecting above vit is cast, molded, or'press'ed a. cement or composition,

brush, but to` adhere to such projecting parts and hold the bristlesiirmly in' place.

The handle of thebrush, which is a contin- .uationof .the back or body, is composed of the com position or cement, an exte1isioua,ot` thc piece or plate a extending intol andne'arly through said handle, which is embcddedin' the cement or composition, so asto either wholly or partially be covered .by it, in which case the extension-piece will serve to strengthen the `from being broken. y

Forthe purpose oi' soI makin a brush,fit is preferred to make use ot` ,a mold, as shown. in Fig. 4, in which AA land Bare its two main parts. .The portion A is a. bedplate,and is perforated with a series ot h'oles to receive und support the bristles, which go through the holes in the manner as shown at b b-b in Fig. 4, and the axis of each ot' these' holes is to be in prolongation of that ot' some one of the vv holes 'of the plate a, which portionl or plate, a, previous to the insertion of the bristles in the bed-plate A, is to be laid on the latter, and is also to receive the bristles which are to'be run through and project somewhat above it.

is tobe forlned with a cavity or matrix, d,A to encompass the edges and top surface of the plate a., and the parts of the bristles which extend above the saidplate a, the 'said cavity d being so formed as to becapable of pressing and .molding upon the top surface and ari-.1st ,the edges ot the plate a a thin strata-.u of the composition when in a soft, plastic, orvmolding state o r condition. This composition may be what is termed hard rubber in a condition proper for being mo1ded,orit may becomlposed ot shellac and comminuted earthy, mineral, or vegetable matters; or it may be otherwise made; or it may he any suitable material -capableofbeingmoldell in adie orcastin arnold, and which subsequently, by exposure to atmos pheric temperature, will become indurated. On applying a suticient quantity of thecomposition to the plate a, when on the bed-plate c, so as not onlyto forni. aback or finish to the handle and aid in p'reventingthe composition The part B is the die or mold plate, which .the brush is effected.

A and duly supplied, wi-th bristles, and subsequentl y forcing the die-pla'tcB down upcn'sucb composition, so as to cause itto'be pressed` upon the plate aandthe bristles, and take the requisite form about the same for makinga backing 'which shall cover the platea norepr less, as circumstances may require, the. bristles are not only fixed in place, but a -nisl n The die or matrix may be made so as to prof duce. an ornamental impression, and the hlillf dle part-a' of the plate a may be forme jini' longitudinalv section, as shown in Fig. Qin.; order that when the composition is forced i'pon it with poyverfulpressure such compositionx'yri afy be caused to pass hetween'the entire lowergsurface ofthe part a and the bed-plate, as well as over the upper surface and about the' edges ot' the said-part a', in which case the part ru' vill' be entirely incased in the composition ,and will serve to aid in preventing breakage ot' it. v

Thepart a' may be in one piece with the rparta, or the two may be made of separate pieces duly applied together, the part a' being of any proper form for conveniently Imolding thecomposition upon it'.

Tlxecompositon generally employed in the manufacture herein described is wh atis used in making molded photograph or miniature Y Ait being composed in part of shellac; but the invention is not confined to such, as varousother compositions or. substances that arewell known will answer the purpose.y

, When the brush is made asherein stated the molds are opened and the brush is easily removed, the bristles readily drawing y out ot' the holes lin the bed-plate..

No claim is made to a brush composed' sim,-

coment or a molded composition; nor is any claim made to the employment vot' a plateto vhold the bristles while being inserted in the composition or while it may be in the act of being applied to them, such plate being sub- .sequently drawn oil' from the bristles, tso as to l leave them adhering'r to the cement or compol'stion back. The-back herein descrbedand iclaimed as theinvention of the said ALANSON 5C. EsrAnnooK-s composed of. a base-piece andv an ,outer back and handle 'made'of suitable compositionv or cement molded onto such base and handle-extension or strengtheningpiece-the exterior' for ornament, vthe interior iforstrength.

What is claimed as the invention of ALAN- sorN C. ESTAB'RQOK, and desired-to` be secured by LettersPatent, is-V l. A back composed lplate of metal or other snitablematerial -to give it requisite strength, and embedded in a composition o rcement that forms in whole or i iu partvthe exterior of the back, substantially as described. 2. In' a back composed of an interior strengthening-pieoe and a.y composition or cement exterior, the .giving of shape, form, and ornamentation toitat the same timoand by the same menns'that presses the plastic material around the strengthener, substantially 'as described.
