DRYDEN BLAIR FORWARD, OF ALTURAS, CALIFORNIA.

BRUSH.

SPECIFICATION forming part of Letters Patent No. 61 1,114, dated September 20, 1898.

Application filed September 23, 1897. Serial No. 652,752. (No model.)

To all whom it may concern:

Be it known that I, DRYDEN BLAIR FOR- WARD, of Alturas, in the county of Modoc and State of California, have invented new and useful Improvements in Brushes and Brooms and the Method of Producing the Same, of which the following is a full, clear, and exact description.

This invention is a brush or broom and a method of producing the same, the brush being formed of wire and being produced by twisting together a number of strands, so that the strands will be given a crimped form, and then partly untwisting the strands, so as to make the individual bristles of the brush.

This specification is the disclosure of one form of my invention, while the claim defines the actual scope of the conception.

Reference is to be had to the accompanying drawings, formingapart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the invention. Fig. 2 is an elevational View of the handle. Fig. 3 is a view of one tuft of bristles, and Fig. 4 is a fragmentary detail view of the handle and the devices for attaching the same to the brush.

The brush is made by taking a number of strands c of resilientwire and twisting said wire together in the same manner that wire or other cable is formed. 7 In Fig. 3 I have shown two lengths of wire bent intermediately to form four strands c, which are twisted together. This plan may be followed or four or any other number of separate lengths of wire may be employed for the same purpose. When the wire is twisted, it is given a crimpedp spiral form. Then when the wire is untwisted the individual strands 0 have the shape of a distended Spiral. Onlya portion of the stfahds' c are untwisted, so as to leaveanpart twisted which formsfthebody of the tuftof bristles, The tufts of bristles are held together to form the brush bya suit-able head a, which is clamped firmly around the bodies of the tufts and which is provided with two braces a, which hold a centrally-located socket a wherein is held a removable handle I). This isbest shown in Fig. 4.. The waved or crimped strands form an efficient brush, since they lie closely together and are to a degree entangled with each other, thus giving the strands of the brush a very efficient degree of stiffness.
