GEORGE G. MORRIS, OE BOSTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND WILLIAM W. EASTHAM,OF SAME PLAGE.

Letters Patent No. 99,338, dated February 1, 1870.

-IMPRovED PAINT-BRUS;

To all whom it may concern.-

Be it -known that I, GEORGE G. MORRIS, of Boston, in the county of Su'olk, and State of Massachusetts, have invented an Improvement in Faint-Brushes; and I do hereby declare that the following, taken in connection with the drawings, which accompany and form part of this specification, is a description of my inven-v tion, sufiicieut to enable those skilled in the art to practise it.

In the man ufaoture of paint-brushes, it is customary to form a wire i'errule, by winding a c'oil of wire and soldering the adjacent wires together, thus making a ring or fer-rule, and to fill this fel-rule with the but'ends of the bristles, driving through the centre of the bristles in the ring the brush-handle, the large end of which compacts the bristles between it and the inner surface of the wire ferrule, the ends of the bristles being flush with the top of the ring, and being covered with cement.

Brushes have been made for many years with a circular cap interposed between ,the`ends of the bristles and the upper opening in the wire ling, said cap being crowded into the end of the ring, and the ends of the bristles butt-ing against its inner surface. These caps hare been made of wood and of cork, and also of a cement composed of sand and rosin, or sawdust and rosm.

Lately brushes have been, to some extent, manufactured having such caps made of leather, as shown in the patent granted to D. \Vhite, November' 24, 1868.

The only'dierence between the construction of suoli' White., and brushes made for yea-rs previous' to said Vhites patent, being that said \Vhites disk or cap is made of leather, while in the previous brushes they were made of wood, cork, or composition.

Inmy invention, I construct a brush with a disk or cap covering the tops of the bristles, such cap being made of pasteboard, applied in a moist or saturated condition, it being filled with a solution of shellac, which not only cements the bristles firmly in position, but causes thedisk or cap to become very hard, rigid, and impervious.

It is iu this construction that my invention consists, or in a paiut-brush having the bristles surmounted by a c ap made of pasteboard, permeated with shell-ae, and applied while in a pliant, moist, and viscid condition, the cap adhering firmly to the bristles when it becomes dry, thereby not only strengthening the brush, but forming a cap which is impermeable to the passage of the oil and turpentine contained in the paint.

The drawings represent a brush embodying my improvement.

A shows the brush in side elevation, the wires being broken away at one point to show the edge of the cap.

B is a sectional elevation ofthe brush.

a denotes the bristles;

b, the wire ferrule;

c, the handle; and

d, the cap. l

The bristles being properly prepared in the oustomary manner, and the but-end of the bunch being placed in the ferrule, the ends are covered with a cement made of white lead, litharge, Sto. 'lhe pasteboard cap having been prepared by soaking in the shellac solution, and being in a soft, visoid, and pliable condition, is pressed into the top ofthe ferrule, the bristles abutting against its inner surface. The point of the handle is then passed through the centre of the free ends of the bristles, and through the ferrule and cap, and isl driven up through the cap until the large end enters the cap-hole, and, expanding the cap, presses its periphery tightly against the inner surface of the cap.

The brush being then allowed to dry, the shellao and cement fasten the cap and bristles firmly in place, and the pasteboard becomes hard and impermeable, as before set forth, not shrinking, as leather will do, un-

I der similar treatment, and not becoming pervious to oil and turpentine,l under the permeable action of which leather becomes soft, and soon breaks away from the cap and bristles.

I claim a paint-brush, having a cap, d, made of pasteboard, treated and applied and rendered hard and impermeable, substantially as descrined.

Executed December 13, A. D. 1869.

GEORGE G. MORRIS.
