BRUSH-J SPECIFICATION forming part of etters Patent Nb. 653,039, dated July 3, 1900. Application filed January 22,'19ot.=' seal-no. 2,269. (No model.)

To all whom it may concern:

Be it known that I, GRANVILLE ROWELL, of Auburn, county of Androscoggin, State of Maine, have invented an Improvement in Brushes, of which the following description,

in connection with the accompanying drawings,is a specification ,like letters on the draw ings representing like parts.

This invention has for its object the production of a novel brush or cleaner particularly adapted for use in cleaning cars, &c., the construction being such that a large cleaning-su rface of fiber is always presented to the part over which the brush is passed.

The various novel features of my invention will be hereinafter fully described, and particularly pointed out in the following claims.

Figure 1 is a central sectional View of a brush or cleaner embodying my invention,

taken on the line m, Fig. 2. Fig. 2 is a face view of the brush-head'with the fibers omitted, and Fig. 3 is a central sectional view of a modification to be described.

I have herein shown the head A of the extent to form a brush proper or cleaning portion, the outer flaring wall a of the groove serving to direct the exterior fibers outwardly, as in Fig. 1, and spread the fibrous portion as much as possible,while the straight wall a affords a firm inner support for the tufts. bent into circular form, is extended through the bights of the tufts and is firmly secured in the groove by staple-like fasteners d which straddle the binder and are driven into the bottom of the groove a, drawing the butts b of said tufts firmly and securely into the groove and retaining them in place. In order to complete the fibrous portion of they brush and fill its center, I make a sufficientlylarge tuft c of the fibers and insert its butt 0 A binder d, preferably. of stout WlI'Q into the recess a of the boss a drawing the butt into the recess by a staple-like binder d passed through the bight of the tuft and driving its legs into the head, a fasteningstaple d straddling the binder and being also driven into the head. By this construction I'obt ain a brush with a full bushy and flaring cleaning portion or brush proper, which may be trimmed to present a partly-spherical surface, the fibers being held securely'in place without the use of glue, cement, &c., and so not affected in the least by water:

The fibers may be made of any suitable material-such, for instance, as cotton string or yarn-which is soft, durable, and holds water well. a

A hole a is made in the head (see Fig. 1) to receive the handle H, and in order to prevent the head from splitting I insert in said .hole a metal ferrule or thimble j, which is provided with external projections or prongs f, forced into the material of the head to prevent withdrawal of the ferrule.

In Fig. 3 the head is shown, as described hereinbefore, with the central filling-tuft 0, but the outer tufts b are externally braced by supporting-tufts g of stiffer material than the body-tufts. The tufts g are turned under the butts b of the outer tufts and up between the said butts and the inner wall a of the groove a, as at g, the short ends of the supporting-tufts extending only a very short distance above the boss, just sufficient to afford a firm hold. By this construction the stiffer support-ing fibers g sustain the bodytufts and prevent undue spreading or breaking down thereof.

Having fully described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. A brush comprising a centrally-recessed head provided with an annular groove in its face having a straight inner and flaring outer wall, series of doubled tufts of fibers inserted in the groove throughout its length and flared by the outer wall thereof, a binder extended through the bights of said tufts, means to fasten the binder in the groove, and a central doubled tuft of filling fibers forced into the central recess and secured therein, substantially as described.

2. A brush comprising a centrally-recessed head provided with an annular groove in its face having a straight inner and flaring outer wall, series of doubled tufts of fibers inserted in the groove throughout itslength and flared by the outer wall thereof, a Wire binder extended through the bights of the said tufts, staple-like fasteners straddling said binder and driven into the bottom of the groove, a filling-tuft of doubled fibers butted into the central recess of the head, and crossed staple fasteners through the bight of the tufts and driven into the head, substantially as described.

3. A brush comprising a head provided with a groove near its edge having a straight inner and a flaring outer wall, series of doubled tufts of fibers inserted in the groove throughout its length and flared by the outer wall thereof, means to retain said tufts firmly in the groove, a filling-tuft of doubled fibers secured to the portion of the head within the groove, and means to retain the filling-tuft in place, substantially as described.

4. A brush comprising a head provided with a groove in its facehaving a straight inner and a flaring outer wall, series of doubled
