Specification of Letters Patent. Patented Aug. 31, 11915? Application filed July 7, 1914. Serial No. 849,538.

To all whom it may concern:

- Be it known that I, CLARENCE E. JARVIS, a citizen of the United States, residing at West Springfield, in the county of Hampden, State of Massachusetts, have invented certain new and useful Improvements in Brushes; and I do hereby declare the following to be a full, clear, and exactdescrip-' tion of the invention, such as will enable others skilled in'the art to which it appertains to make and use the same.

This invention relates to brushes and particularly to the manufacture of brushes of the type utilized. in polishing and finishing 1% shoes.

p The object of the invention resides in the provision of an improved method of manufacturing a brush-top or web which will positively hold the bristles in the web and enable. the web to be quickly and efi'ectively mounted upon a brush head.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying W drawings wherein like characters of reference denote corresponding parts in the several views, and in which Figure 1.is a perspective view of a 'por-,

tion of a, web of bristle showing the first step in the manufacture of the improved brush; Fig. 2, a view similar to Fig. 1 showing the second step in the manufacture of the improved brush; Fig. 3, a perspective view showing the third step in the manufac- W ture of the brush; Fig. 4', a pe'rspectiveview showing the fourth step in the manufacture of the brush; Fig. 5, a perspective view showing the manner of applying the brush Web to the head or hub of the brush; Fig. 6,

F a side view of the brush complete with the near flange removed; Fig. 7, a transverse section through a complete brush, and Fig. 8, an edge view of a complete brush.

Referring to the drawings 10 indicates the W bristles or brush-stock, which are of equal length, or substantially so, and are prepared in the usual manner. These bristles are arranged in a layer of suitable thickness, the bristles lying atv full length with their ends in line as shown in Figs. 1 and 2. A paper the latter together.

tape 11 is then placed against one side of the layerof bristles along the middle of said layer and a metallic wire 12 placed against the opposite side of the layer centrally of the bristles andtransversely of the latter, as clearly shown in Fig. 1. A second paper tape 13 is then laid over the metallic wire 12 and disposed correspondingly to the tape 11. The paper tapes 11 and 13 are then united or fastened together with the bristle and wire-between them by means of lines of stitching 14 and 15 which are formed upon both sides of the central longitudinal line of the tape as clearly disclosed in Fig. 2.

When the web has been produced in this manner of any suitable length it is folded upon the central longitudinal line of the paper tapes 11 and 13 with the tape 13 and wire -12 disposed inwardly or between the bristles. After the bristles are thus folded they are maintained in this relation by means of stitching 16 passing through the tapes 11 and 13 and through the bristle as clearly shown in Fig. 3, it being noted that the ends of the wire 12 project beyond respective ends of the web. The tape 11 is then removed and the-bristles adjacent the line of fold are soaked in pitch which will permeate all of the bristles and serve to bind This status of the web is shown in Fig. 4. While the binding pitch is plastic the web is secured to a brush head 17 by securing one end of the wire 12 to one end of the head by means of a. staple 18 and then winding the web around the head in the manner shown in Fig. 5. When the web has thus been-completely applied to the head 17 the other end of the wire 12 is secured to the opposite end of the head 17 through the medium of a suitable staple. The web is then further secured to the head 17 by means of staples 19 corresponding arms of which are engaged in the ends of the head and their other corresponding arms through the portions of the bristles bound together by the pitch. The brush is then placed in the usual press and set after which it is-removed and the flanges 20 applied to opposite ends of the head 17. The working ends of the bristles are then trimmed in the usual manner and the brush is complete.

What is claimed is The herein described method of manufacturing webs of brush-stocks consisting of applying paper tape to opposite sides of a 11W bristles and tapesto preserve the fold, re- 10 moving the central part of the resulting outer tape adjacent the line of fold and then immersing the portion of the bristles adjacent the line of fold in a suitable binder.

In testimony whereof, I afiix my signature, in the presence of two witnesses.
