BRUSH.

SPECIFICATION forming part of Letters Patent No. 783,134, dated February 21, 1905.

Application filed June 21, 1904:- Serial No. 213,518.

To all whom, it nuty concern:

Be it known that I, DON O. PRATT, a citizen of the United States, residing at Binghamton, New York, useful Improvements in Brushes, of which the following is a specification.

My invention relates to paint and varnish brushes, and has for its objectthe production of a brush which will be at once cheap and durable.

One of the greatest defects in many of the brushes now in use is the loosening and falling out of the bristles after the brush has been in use a short time. To overcome this fault, I have devised a brush in which the internal fastening for the bristles is spherical in shape and is entirely separate from the handle, this preventing any movement of the fastening device or center which would tend to loosen the bristles.

With this object in view my invention consists in the construction hereinafter described, and more particularly pointed out in the claims.

In the drawings, Figure 1 is a sectional view of a brush embodying my invention. Figs. 2 and 3 are similar views of the brush and handle, respectively, before they have been assembled.

Referring to the drawings, A is the brush proper or bunch of bristles the upper end of which is contained in the ferrule B, which is shown as having an annular depression in the interior thereof. The bristles are retained in place within the ferrule by the ball O, of metal or any suitable material, which is forced into place under pressure. The bristles are so placed that when they have been secured'in place there is sufficient space between the uphave invented certain new and per ends of the bristles and the upper end of the ferrule to receive the disk (Z, which forms the lower end of the handle D. This handle is secured in place by nailing or any desirable means. As will be seen, the handle and the ball are entirely separate, and any movement of the handle in relation to the brush in the operation of the same will not be communicated to the ball; but the ball remains stationary. By the use of the ball the bristles are under uniform pressure on all sides, and I get the spring of the bristles clear to the ferrule.

This brush is very simple in its construction and may be easily and cheaply manufactured, as it requires no machinery. Having described my invention,

what I claim is 1. In a brush, the combination with the handle, the bristles and a ferrule surrounding a portion of the bristles, of a ball within said ferrule and entirely surrounded by the bristles, substantially as described.

2. In a brush, the combination with the handle, the bristles and a ferrule having an annular depression, of a ball within said ferrule and surrounded by said bristles, substantially as described.

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

DON O. PRATT.
