BRUSH.

SPECIFICATION forming part of Letters Patent No. 367,031, dated July 26, 1887.

Application tiled January 30, LSSB. Serial No. 190,342.

To all whom, it may concern-.-

Be it known that I, OREN FIsH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Brushes7 of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improvement in brushes, and is designed as an improvement on Letters Patent No. 307,711, issued to me November 4, 1884.

The invention consists in certain details of construction and combinations of parts, as will be hereinafter set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of the form of paint-brush shown in my aforesaid patent with the particular improvements hereinafter explained applied thereto. Fig. 2 is a vertical section of a sash-tool with my improvements applied. Fig. 3 is a similar view of a driven-handle. brush. Fig. lis asectional view, ou an enlarged scale, indicating the manner in which the two convex or crowning surfaces coact to clamp the bristles in place. Fig. 5 is a detail View of the form of metallic center employed in the driven-handle brush shown in Fig. 8. Fig. Gis adetail view of the metallic center piece used with the form of brush shown in Fig. 1.

Like letters are used to indicate correspond ing parts in the several figures of the drawin s. i

.gReferring to the drawings, A designates the brush-ferrule or band having a shape corresponding to the forni of the brush that is being constructed. On the inside of the ferrnle, at a suitable intermediate point between the npper and lower edges, is provided an inwardlyprojecting flange, projection, or shoulder, a, which is connected or joined by transverse bars or partitions b, (see Fig. 5,) when the ferrule or band is made wide, as in the flat brush used for pasting purposes, said bars or partitions serving to brace the ferrule and overcoming all tendency of the latter to burst or spread.

In the construction shown in Figs. 1 and 3 I employ a top piece for the ferrule, while in (No model.)

Fig. 2, where a sash-tool is illustrated, the handle serves as a top piece, or rather the latter is formed integral with the handle. Referring more particularly to Fig. 1, the top piece, B, is provided with a central vertical passage, d, and a crowning or bulged bottom, e. The sides of the bottom or under side of piece B are made ilat, as at f, so as to rest upon and be supported by the tlange or shoulder a, the crowning portion e of the bottom extending from the flange a and projecting through the opening or passage left in the center of the ferrule by the flange.

The top piece, B, is received entirely within the ferrule,and has its plain upper face aligned with the upper edges of the ferrule or band. The handle C has its lower end reduced in diameter to leave a tenen, g, which is inserted through and tits within the passage d of the 7o top piece, B. A screw, I), having one end formed with threads for metal and the other end with threads for wood,has the latter endscrewed into the lower end of the handle and its for mer threaded end working through athreaded perforation of the metallic center piece, E. The said center piece is made convexe-plano in cross section, and has its periphery or edge cut outat intervals, as at 7L, to leave intervening points t, the sides of which are inclined in reverse directions. At thejunction of the points with the body of the center piece, E, is provided an inclined wall, j. It will be understood that this construction gives to the center piece a shape similar to a multiple-pointed star, and this I have found in practice to be a great improvement over the plain center pieces heretofore employed in this connection. rlhe points t' ofthe center piece (see Figs. 6 and 7) have their side walls inclined vertically as well as laterally, the base of the points being considerably wider than the top, while the extreme ends of the points t' come to a thin edge.

It will be seen that when the center piece is in position its upper convex face serves to crowd the bristles up within the brush-cap.` rIhe spaces 71. between the points t provide compartments for the reception of the bristles, and the points themselves serve to press, clamp, or bite against the mass of bristles and hold them in place.

IOO

The peculiar shape of the points, as shown and explained, contributes to the holding action thereof, the thin outer edge of the points biting against the mass or bunch and pressing the latter in contact with'the sides of the ferrule or band. The bristles when received in the spaces h will be clamped therein by the contact of the two opposite inclined faces of the points t' and the inclined wall j, acting in conjunction with the under side of the top piece.

In Fig. 4 is illustrated an enlarged sectional view of the ferrule, top piece, and metallic center piece, showing the manner in which the convex upper face of the center piece cooperates with the crowningor convex bottom of the top piece. .It will be seen that these two convex faces oppose each other, and when the center piece is in proper position'the butts or inner ends of the bristles are crimped or turned over, as shown in Fig. 4, and held be' tween the two convex faces, thus making it impossible for the bristles to work loose or out of place when the brush is in use.

In constructing a sash-tool as shown in Fig. 2, the lower end of the handle C is en larged in diameter to provide a top piece, B, for the ferrule A, the latter having the flange or shoulder a to support the lower end of the top piece on the handle.r Said top piece has its bottom bulged or crowning and arranged in a similar manner to what is shown in Fig. I. rIhe metallic center piece used in the sashtool, Fig. 2, should be of a greater convexity than when employed on the ordinary form of paint-brush seen in Fig. 1. The metallic centerpiece coacts with the crowning or bulged bottom of the top piece, which is formed integral with the handle, in the manner shown in Fig. 4 and d( scribed above.

In, Fig. 3 is shown, what is termedy as a drivenhandle brush, the ferrule A with the flange or shoulder a, the top piece, B, having the crowning bottom, and the convexo-plano center piece, as hereinbefore described, being employed. The handle C is driven through and wedged in the central opening of the top piece, the center piece, E, having a plain central opening to be received over and around the tenon on the lower end of the handle. The bristles are first adjusted in posi-tion within the ferrule, when the handle carrying the ferrule is inserted through the center ofthebuneh of bristles into the brush-ferrnle and wedged in position, as explained.

The' co-operating action of the convex or Wedgeshaped center piece with the crowning top piece is the same in all essential particulars in the driven-handle brush as in the screw-connection, and hence need not be repeated here.

I do not wish to be limited to the use of the crowning bottom as applied to brushes having the top piece separate from the handle, as the salneimprovement may be applied to the lower end of the handle, the latter in that case serving all the purposes of the top piece.

I lay special stress on the combination of the crowning bottom ot' the top piece with the convex or Wedgeshaped center piece, as by means of the same the butts or inner ends of the bristles are crimped over between the two faces and cannotfallout. Again, this arrangement causes the flag or center of the brush to assume a similar shapeei. e., the center crowning or longer than the sides-thus giving a longer hold on'the side bristles of the brush (where the greatest strain comes when in use) than on the center bristles, besides shaping the brush and saving the length that would otherwise have to be trimmed off. The metallic center piece produces a practically solid center brush, allowing the latter a sufficient amount of spring without wearing down stiff and scattering paint when in use. This center piece also holds the bunch of bristles more secure than aplain-surface center piece, as the star-points afford agreater holding-surface than could be the case where the holding action depends merely on the wedge shape of the piece.

Having described my invention, I claim 1. In combination with the ferrule or band having an internal flange or shoulder, thc top piece fitted in the ferrule or band and resting at the edges of the bottom on the ange or shoulder, the top piece having a crowning or bulged portion at the bottom,which crowning portion projects through the space left by the an'ge or shoulder, as set forth.

2. I n combination with thewedgeshaped or convex center piece, the top piece having a bulged, crowning, or convex bottom arranged with its curved face opposite to the curvature of the center piece, as set forth.

3. In combination with the ferruleor band having an externalange or shoulder, the top piece resting on the flange or shoulder and having its bottom made convex or crowning and projecting through the space between the flange or shoulder, and the center piece having a convex upper face arranged opposite to the bottom of thetop piece, as set forth,

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

OBEN FISH.
