IIVIPROVED BRUSH.

Specification forming part of Letters Patent No. 511,464, dated May 1, 1866.

tive views of the hollow cone or thimble, by

means of which the bristles are held in place. My invention relates to certain improvements i in brushes for which Letters Patent of the United States were granted to me on the 19th day of September, A. D. 1865, in which the bristles were secured in a socket by means of a conical metallic wedge and screw. This solid metallic wedge, however, especially in a large brush, added considerably to its weight, ren dering` it inconvenient to handle. My invention has for its object to avoid this objection; and it consists in substituting for the solid cone above described a hollow metallic cone or thimble, whereby the weight ot' the brush is considerably reduced and a cone ot' much larger diameter may be employed, if desired.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, Ais the metallic socket, the lower portion of which is for the reception of the bristles B, while into the upper portion is fitted the handle O.

D is a hollow sheet-metal cone or thimble of the form shown in Figs. 2, 3, and 4, and of a length suflicient to extend nearly to the botton'i of the socket A. The top c of the hollow cone D is perforated, as seen in Figs. 2 and 4., for the passage of a screw, a, which passes up through it and the partition b into the upper portion ot' the socket A, where the wooden handle O is screwed down upon it. A screwthread is cut in the partition b, which is made thicker at that point by the addition of an eX- tra piece, d, so as to hold the screw a and cone D rmly in place independently of the handle U, which, however, when screwed down into place, serves to hold the parts together with additional strength.

The bristlesl B are thus wedged tightly in place against the sides of the socket A by the hollow cone or rthimble D-and screw a, the partition b preventii'ig the handle from being driven down through the bristles in case ot' its shrinking or the bristles from being forced up, thus avoiding all liability of the brush fallin g to pieces, while the cone D, being hollow, is exceedingly light, and makes no perceptible addition to the weight of the brush.

In constructing this brush the bristles are Iirst placed in the lower portion ot' the socket A. The hollow cone or thimble D is then passed up through the center ot' the bristles and secured in place by means ofthe screw a, the head ot' which rests against the under side ot' the top c ofthe cone', thus wedging thebristles tightly in place. The handle O, provided with a suitable hole at the lower end, i-s then screwed down onto the end of the screw @,and the brush is ready for use.

What I claim as my invention, and desire to secure by Letters Patent, is-

The hollow metallic cone or thimble D, substantially as and for the purpose set forth.
