SPECIFICATION forming' part of Letters Patent No. 290,522, dated December 18, 1883.

Application filed September 10, 1881. (Model.)

.To @ZZ whom t 71mg concern:

Be it known that I, Gnonen BniNrzrNe- KOFFER, a citizen of the United States, residing at Philadelphia, inthe county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Brushes, of which the follving is a specification.

My invention relates, especially, to that class of brushes which are frequently Wet or submerged in Water for bathing, scrubbing, scouring, and other analogous purposes.

It is the object of my invention to provide a strong, ileXible, durable, light, and cheap brush, which Will be in nowise impaired by moisture or constant wetting. This object I attain by the construction ofsbrush hereinafter described, and illustrated in the annexed drawings, in which- Figure lis a perspective view of a deshbrush especially adapted for Turkish and other baths. Fig. 2 represents a side vieuT of a brush especially designed for light scrubbing or scouring. Fig. 3 is a transverse section through the brush shown in Fig. 2.

In all of the brushes herein represented the bristles AV are secured in a face, B, of rubber, which will usually be composed of an eXtra-thiol; sheet of vulcanized or hard rubber. It will be evident that this face will not be impaired by constant wetting, Whereby, no matter how long the brush is used for bathing, scrubbing, or scouring purposes, the said face will not Warp or crack, and hence the brush will practically be an exceedingly cheap one.

The letter C indicates a secondary or supplemental leather backing, which is secured to the brush-i`ace in order to cover the perforated back and conceal the inner ends of the bristles. This backing consists of a leather sheet of the same extent of surface as the face, and of a greater or less degree of thickness, as may be desired. The rubber face is formed with a marginal line of perforations, and the secondary or supplemental leather backing is formed with a marginal line of perforations coinciding with that of the rubber back, so that when the two parts are placed together they can be secured by a line of stitching, D,as shown.

The leather can be varnished or prepared in any Way which Will render it Water-proof, and can have any desired ornamental color and finish. I prefer leather for the secondary or supplemental backing, since it is not usually necessary to have a heavy backing for the brush, and also because it is light, tough, and durable, and capable of having its surface permanently Waterproofed. Other substances, however, than leather might be employed-such, for example, as paper or other similar material.

The brush shown in Fig. l has a leather or other suitable handle, F, whereby it can be readily employed as a flesh-brush in a bath.

In all forms of brushes the manner of applying and securing the tufts of bristles is essentially as follows-that is, the rubber face is first formed in a suitable manner, for example, molded into form Whiley in a plastic state, and afterward vulcanized, and then it is drilled or bored with a seriesY of perforations or holes of uniform size, which extend through the rubber face. The tufts of bristles of uniform size are then inserted inthe said perforations, and their inner ends are secured by Wires or equivalent means. The supplemental backing is then placed on the rubber face and secured by stitches, as hereinbeiore set fort-h.

By constructing the vulcanized face, as described, with the marginal line of perforations, the brush can be made complete, with the exception of the supplemental backing, and sold in that form to the trade, leaving it to the lat-ter to apply any form or particular construction of backing desired by the customer. Furthermore, if it becomes necessary from any unforeseen cause to supply additional bristles, the supplemental back can be readily removed ivithout disturbing the perfect bunches of bristles and the vacant places reiilled, after which the same or other backing may be-applied. Then, again, by providing the marginal perforations for the attachment of the supplemental backing, no injury is liable to result to the bristles.

I do notbroadly claim a hard-rubber brushbacking having holes in which the bristles are secured, and said rubber face provided with a backing of leather or similar material, but

That I do claim as'my invention is As an article of manufacture, a brush composed of a vulcanized or hard rubber face IOO formed with a series of holes into which the hand in the presence of two subscribing Witbristles are introduced and fastened7 and pronesses. vided With a marginal line of perforations for T T the passage of fastenings to attach a supple- GEO BRE TZIL GHOFFER 5 mental backing thereto, substantially as de- Witnesses:

In testimony whereof I have hereunto set my THos. S. STOUT.
