IMPROVEMENT IN PAINT AND VARNISH BRUSHES.

'Specification forming part of Letters Patent No. 149,725., dated Agri 14, 1374; application filed September 19, 1873.

To all whom 'it may concern:

Be it known that I, J Oi-IN W. COOPER, of Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain y new and useful Improvements in Paint and Varnish 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 ywhich it pertains to make and use it, reference being had to the accompanying drawings, which form part Of this specification.

My invention relates to improvements in paint, varnish, Vand other similar brushes, whereby economy of manufacture and greater serviceability when new, combined with greater durability, are obtained.

In the accompanying drawings, Figure 1 represents a section, and Fig. 2 a detail view, of parts of a brush arranged according to my invention.

a is the ferrule,'having a bell-shaped top, which presents no sharp corners or angles, which enables the operator, when the handle is inserted, to holdvand handle the brush with perfect ease'and freedom from the annoyance occasioned bythe sharp edge presented in ferrules as usually formed, and is provided with the flange b. c is thc handle, made tapering, and of such size that, when driven tight into the ferrule, its inner end is slightly outward of the line l l, Fig. 1. It forms a supportmto hold in place the dished cup hereafter described, and is provided with the hole e for the reception of the shank of the plug. F is a dished cap, whichflts within theferrule against the end of the handle, its rim tting against the upper surface d d'. The bristles o rest against this cap, and its shape gives a convex form to the outer end of the brusha form very much desired, but which is not found in new brushes as ordinarily constructed. It is provided with a central Openin g, corresponding to the hole in the handle through which the shank of the plug passes. gis the wedging and supporting plug, provided with the shank g3, to be driven into the handle. It is'made slightly oval, its bulge being on a line with the rim of the ferrule. At its bulge it is nearly severed by the circulargutter r, forming the two parts g1 and gum band or sleeve h.

g2, connected by the neck r. The part g2 is the wedge which holds the bristles o in the ferrule. The part g1 extends below the rim of the ferrule, and serves, when the brush is new and the bristles long, to support and keep said bristlesin better shape until the brush becomes worn away, when, by cutting off said end g1 at the neck r', the remainder of the brush becomes ilexible and available forV further use. h is a removable elastic gurn band or sleeve. I use this to hold the bristles together when being inserted into the ferrule. It also operates, in conjunction with the end g1 of the plug, to hold the bristles firmly in position during the early use. of the brush, and prevents the ow and accumulation of paint upon so much of the bristles as it covers. It is turned back or removed entirely, as may be desired, when the brush is worn down so as to necessitate the removal of the end g1 of the plug. When the bristles are secured in the ferrule the band is drawn up on the ange b, and is held by the drip-cup. 'i is a drip-cup, so constructed as to fit neatly over theferrule and against the iian ge b, and so as to form a wide receptacle, extend ing below the rim of said ferrule, for the purpose of catching'any running or dripping paint when the brush is' used in a position to cause the paint to ow toward the handle. Its wide mouth readily permits the paint to run out when the brush is turned down. It ts over and against the flange b, and holds securely the It may be removed at pleasure with ease, in which case the gum sleeve is drawn slightly farther up On the ferrule, where it will be held from slipping by its elasticity and the flange b. Its position enables the operator to catch the brush well down on the ferrule. The curved flange forming the cup serves as a rest and support for the fin gers, and the concave top Of the ferrule as a rest for the thumb, thus permitting the brush to be handled vwith great ease, and with little or no fatigue to the hand.

In the manufacture of my brush I use some suitable material for lining the ferrule'which will adhere to and not slip yon the metal,which enables me to more perfectly secure the bristles within said ferrule.

In the manufacture of the brushthe handle is driven into place and the cap pnt into position. The bristles having been properly prepared and placed Within the elastic band, the end to be inserted in the ferrule is (lipped in shellac and inserted and pressed well again st the spherical cap. The bristles are parted in the center by a suitable instrument, and the plug, having its shank previously dipped in White lead or other suitable material, is driven into the handle. The end of the gum band is drawn up over, and the drip-cup put on, the ferrule and pressed down against the flange.

It will be readily seen that my brush can be rapidly constructed, and that it forms a substantial and economical implement, as Well as presenting a neat and handsome appearance when completed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In combination With the handle c, ferrule a, bristles o, and gum band h, the Wedging and supporting plug y, for the purpose specified.

2. In combination With the handle c, ferrule a, and bristles o, the spherical cap f, for the purpose specified. 4

3. The improved brush formed of the ferrule a, drip-cup i, handle c, spherical cap f, Wedging and supporting plug g, and gum band h, all arranged as described, and for the purpose specified.

In testimony that I claim the foregoing I have hereuntoset my hand this 12th day of September, 187 3.

JOHN W. COOPER.
