BRUSH.

SPECIFICATION formingpart of Letters Patent No. 416,590, dated December 3, 1889.

Application filed September 2'7 1888. Serial No. 286,526. (No model.)

To all whom it may concern.-

Be it known that I, VILLIAM H. GATES, a citizen of the United States, residing at De troit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Brushes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference be ing had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to brushes, and particularly to the manner of securing the bristles to the bruslrbody.

The object of this invention is to produce a cheap, light, and durable brush, all of which will be fully hereinafter set forth, the essential features being pointed out particularly in the claim.

In the accompanying drawings, forming a part of this specification, Figure 1 is an illverted plan of a brush-body embodying my device, showing chambers and relative positions of the anchor or binding wires. Fig. 2 1s a sectional longitudinal view of a completed brush embodying my invention, as taken on dotted line 00 00 of Fig. 1, showing the bristles 1n the chambers of the brush-body and the anchoring or clinching of the wires that bind them in place. Fig. 3 is a View of the anchor or binding wire as ready for use. Fig. 4 is a modification of same.

B, in the drawings, represents the brushbody; a, the circular chambers or pockets located therein; 0, the partitions between the chambers, Z and Z, the anchor or binding wlres.

In making my improved brush I first provide the brush-body B, which is made, preferably, of wood, with the circular chambers a. Said chambers are located at such distance from each other as will leave the partitions c the desired thickness. These chambers along both edges and across the ends of the brushbody are made to slant outward, so that the bristles when forced into them will stand out, thus giving the brush its proper shape.

The bristles D, which may be of any suitable material and of such length that when once doubled will give the proper length of bristles for the purpose required, are taken in sufficient quantity to fill the chambers or pockets a. when doubled at their center, and the doubled portion placed in said chambers. Then the anchor or binding wires Z and Z are placed centrally across the bristles in the chambers, the bent ends e of the anchoringwires Z and Z projecting into the chambers a, the body of said wires crossing the partitions 0. This position of the wires is clearly shown in Fig. 2 in such position. The anchor or binding wires Z and Z are forced down through the partitions 0, cutting their own groove or passageway therein, whereby the bristles are firmly pressed into the chambers a, and the points 6 of the binding-wires coming through the back of the brush-body and being clinched, as shown at e in Fig. 2, securely hold the bristles in place.

By causing the wire strand to force its own way through the partitions c it is secured against lateral motion and more firmly anchored in its place.

In some instances, and especially when using hard wood in making the brush-body, it will be necessary to employ the modified form of anchor-wire shown in Fig. 4., in which n represents the flattened side of the wire, -e its turned and sharpened ends, 2' its under cutting-edge. Said edge will readily cut its way through the partitions 0, when securing the wires to the brush-body, as hereinbefore described.

It will be observed that in making the herein-described brush a brush-body of less thickness can be used than is required in making brushes where a deep groove is employed to receive the bristles which runs the entire length of the brush-body. In my device the partitions greatly strengthen the brush-body, which enables me to use a thinner brush-body than is the common practice, thereby saving material. I also save in the bristles used, as it does not require so many to fill the chambers of my device as are required where a continuous groove is used and filled.

One of the principal features of my invention is the function of the short anchor-wires Z, which are located across the end and in tions between said chambers, the bristles doubled within said chambers, the binding- Wires having rightanglc end portions, said wires crossing the bristles and the chambers both longitudinally and transversely of the brush-body, their ends being clinched through the brush-body, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

\VILLIAM ll. GATES.
