METHOD OF MANUFACTURING SO-CAL LED CHISEL-BRUSHES.

SPECIFICATION forming part of Letters Patent No. 392,420, dated November 6, 1888.

To all whom it may concern:

Be it known that I, OREN FISH, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in the Method of Manufacturing so-called Chisel-Brushes, and I do hereby 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 pertains to make and use the same.

My invention relates to an improved method for manufacturing so-called chisehbrushes, in which is employed a band in which the bristles are assembled with, preferably, a removable plug placed in the band for the butt-ends of the bristles to rest on, such plug having a tapering or beveled end corresponding with the desired chisel-point of the brush,whereby with bristles of equal length the fag ends of the bristles are brought in the desired form for the brush. Next, the bristles are bound, removed from the band, and the butt-end of the bundle is squared off, leaving the bundle of bristles in condition for attaching to the brush-handle,to the end that with such method and mechanism employed. a great saving is effected in the initial cost of the brushes and the latter are made uniform. In manufacturing brushes the fag-ends of the bristles, be-' ing the valuable portion for wear, are left intact, and any trimming that is done should be at the butt-ends of the bristles. Heretofore in manufacturing this class of brushes the practice has been to bind thebristles for a brush in a bundle having the fag-ends even, and then to trim off thebutt-end of the bundle to the shape desired for the chisel end-of the brush, after which the shorter bristles of the bundle were slid endwise to square off the butt-end of the bundle, thus transferring a chisel-point to the flag-end of the bristles, after which the bristles were fastened to the handle. Such practice was slow and expensive,requiring the labor of skilled workmen, and even then the brushes were not uniform, it being exceedingly difficult to hold all the bristles in their proper relative position while shifting them endwise to square off the buttend of the bundle. I have, therefore, de-

vised the method, as illustrated in the accom- 5o panying drawings.

Figure l is a view in perspective of a completed chisel brush. Fig. 2 is an elevation in section. Fig. 3 is a plan, and 'Fig. 4 is a view of the bristles in position to be attached to the handle.

A represents a band, usually of metal, and of suitable size for assembling therein the bristles for a brush, and corresponding in section with the desired form of such brush. 7 6o Bis a plug, usually of wood, the reduced end of which is made to fit easily in the band A. A shoulder, B, of the plug abuts the lower end of the band, so that the plug always extends the same distance into the band. The lower end of the plug is usually left square, and is of considerable size, so that when the plug and band are assembled they will stand upright on the end of the plug. The upper end of the plug is beveled off on opposite 7o edges, or tapered to form the point b, the lat ter corresponding with the desired chiselpoint of the brush.

Bristles, as they are bought in the market, are assorted to length, and bristles O are assemblcd in the band A, the butts of the bristles resting on the end of the plug. By reason of the pointed or beveled end I) of the plug,to which the butts of the bristles conform, the fagends of the bristles are made to come spond with the point I) of the plug, thus forming a chisel-point, c, for the brush. The bristles G are next temporarily bound by cord or band a above the band A to hold them in place, after which the bundle of bristles is removed from the band and the butt-end of the bundle is squared off, thus leaving the bundle of bristles in condition to be attached to the handle in the ordinary manner.

The plug B being removable any number of plugs having different shaped ends I) may be used in the same band A; otherwise the plug, or a bottom of the desired form, might be rigidly attached to band A. The saving thus effected over the old method aforesaid is con- 5 siderable, and the brushes are made uniform.

N o skilled labor is required, and the only trimming of the bristles required is to square off the butt-end of the bundle, and this may be done in a moment.

XVhat I claim is- The herein-deseribed method in the menu- 5 facture of so-called chisel-brushes,consisting. essentielly,in assembling the bristles in a band with the butt-ends of the bristles resting on a plug or bottom, the latter corresponding with the desired chisel-point of the brush, binding 10 the bristles thus assembled, and then removing the bristles from the head and squaring off the butt-end of the bundle, substantially as set forth.

In testimony whereofIsign this specification, in the presence of two witnesses, this 7th day 15 of July, 1887.
