.Letters Patent No. 39,439, August/1, 1863; fre/issue No. 3,235, dated December-15, 1868.

IIMPROVED BRUSH +4. The Schedule referred to in these Letters Patent and making part of the same.

.had to the accompanying. drawings, making part of my. specification.

x Qf such drawings- Figure 1 is a sidevew, v

A Figure 2, a transverse section, and

Figure 3, alongitudinal section of a brush provided with my invention.

The nature or piincipleof my invention consists in the direct combination of a Wedge or cone With the handle. of a brush, so that the two may be in one piece, or thewedge or conebe formed on the handle, whereby the wedge or cone, when arranged within a mass of bristles, in manner as represented in the accompanying drawings, and encompassed 'by a ferrule, shall not only perform the function of distending such mass, so as to cause it to fit closely tothe ferrule, but shall serve at the same time, and with cement, to securely hold the handle in connection with the mass. The arrangement of the wedge'with'in the handle is such that the base of the wedge is connected to the handle, and is of a less size. or diameter, relatively to the base of the handle, so that there may bek a shoulder at the end of the hand1e,to encompass the base of the wedge, and serve as a support to the ends of the bristles, and also as-anl additional means of holding th em in place through the aid of cement or pitch interposed between such shoulder and the adjacent ends of the bristles.

The use of pitch forxing a wedge driven into a mass of bristles, when enclosed withina ferrule, is old, but in this case .the Wedge has been separate from or not formed on the handle, or has been a'simple tapering ferrule driven into the mass ofbristles, Vand designed to expand such mass into the ferrule, and hold and support a handle.

To enable a person skilled in the art of brush-making to make, construct, and use my improvement with reference to the brush-handle and wedge,1 will now proceed to describe it more specifically, and also the method of applying it to aymass of bristles -and a ferrule, yso as to form a brush. v

In the drawings- A denotes the mass of bristles;

B, 4the ferrule,

C, the handle; and V C the wedge, point, or cone.

The shoulder is represented atl) D in fig. 3.

The said parts C and' C are in one piece of wood or material with the shoulder.

j When having a shoulder as described, arranged and 'combined With'the parts C O', in manner4 as set forth, the part C, or handle-portion, will not only be connected in one piece with the wedge, but it will also be con- .nected with the bristles, at their next adjacent ends,

through the intervention of the cement.

The shoulder has advantages, particularly with reference to the handle and wedge, or cone, when formed in one piece of material, and arranged in manner as` represented, for, under such circumstances, the shoulder, in case of shrinkage of the Wedge or cone, will, by

being cemented to the ends or buts of the bristles, serve to keep the bristles from being drawn or worked down in the ferrule while the brush is in use, the connection.

of the wedge or cone with the handle at the same time serving to keep the wedge in its proper place, and to cause the handle to be much better supported and less liable to work loose in the ferrule, while the brush may be in use, than would be the case were the handle and wedge, or cone, disconnected.-

. When the handlel and cone are connected, and provided with the shoulder, the latter renders it practicable to use shorter stock, a shorter ferrule, and a shorter wedge, or cone, to the handle, in constructing a brush, than is the case when the handle and cone are disconnected. The brush is consequently rendered neater in appearance, of less weight, and therefore .easier to be operated, or less tiresome to a party who may use it. Furthermore, the wedge, or cone, when connected with the handle, causes the bristles to give sueh'support to the handle, while the brush may be in use, as to prearranged, and provided with a shoulder, as described,

a tapering ferrule arranged with them, in -manner as represented, presents advantages which are -not attained by acylindrical ferrule. It holds; the mass of bristles better in place, admits of more bristles being used in the mass, the handle to be made Vlarger in diameter atits base, the bristles to be spread more by the wedge or cone while being driven into the mass, and, as a consequence, a better securing of the wedge on cone to the bristles, and of course the bristles to the handle, than would result werethere no shoulder lor were there one, and the wedge, or cone, and the handle were disconnected.

An important advantage possessed by my formation ofthe handle and Wedge, or cone, in one piece of wood or material, and their arrangement together, as represehted, is that such saves the employment aud cost of any screw or separate means of uniting the two, which would be requisite were they in two pieces.

If the ferrule has a taper corresponding with that of the wedge, or cone, the bristles will be held to the ferrule by a uniform lateral pressure, limitedl by the strength of the ferrule, and the ability ofthe handle andthe wedge, or cone, to resist compression. Besides,

the taper'of the ferrule enables thebxistles to be spread at their buts, and Within `the ferrule, and about the Wedge, or cone, so as to cause the cement to hold them to very much better' advantage than they would b e in a non-tapering fel-rule.

rllhe ferruleI may be made of metal or other proper material; and to perate'to` best advantage, should be provided with a taper 'to correspond with or about with that of the Wedge, or cone Y After having dipped to the necessary extent the upper or but-end of the mass of bristles in cement or pitch, I next insert the flag-end of the mass' into the upper end, and through the ferrule, and draw the mass into place therein, so that the but-end shall be within the fer-rule, and at a short distance from the upper vend of it, or that end 'which is to abut against the handle. Having dipped the wedge, or cone, or the shoulder of the handle, in cement, pitch, or some proper resinous matter, the Wedge, or cone, is next to be forced into the mass of'bristles at its but, so as tospread the mass, and bring the shoulder down Within the ferrule, and cement it to the buts of the bristles, which, by the shoulder and cement, will be thus covered and protected from Water or liquid, which might otherwise get into the but of the mass when the brush is placed within Water. l

Vhat I claim as my invention, is-

Ihe wedge as forming a part of or being-in eonneetion with the handle, as set forth.

Also, the wedge and handle thus combined and constructed with the shoulder, the Whole being substantially as specifed.
