BRUSH.

SPECIFICATION forming part of Letters Patent No. 349,649, dated September 21, 1886.

Application filed May 7, 1886. Serial No. 201,437. (No model.)

To all whom it may concern.-

Be it known that I, WILBUR F: HOWARD, of Glaremont, in the county of Sullivan and State of New Hampshire, have invented a new and useful Improvement in Brushes, of which the following is a full, clear, and exact description.

My invention relates to an improved construction of brush, whereby a substantial artiele'is producedin a simple and cheap way.

In the accompanying drawings, Figure 1 is a perspective view of a brush embodying my invention, part of the head-stock being broken away. Fig. 2 is aplan of the under side of the I 5 brush 011 the line 3 3 Fig. 3; Fig.3, a crosssection through the head-stock on the line a: 00, Fig. 2; Fig. 4, an enlarged perspective view of the end fastening; Fig. 5, an enlarged crossseetion through the head stock on the line x w,

Fig. 2; and Fig. 6 is a view of a part of the core.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the handle 2 5 and B the head-stock of my improved brush. Any suitable shape or outline may be given to these parts, which may be made of one or more pieces. In the lower part of the headstock one or more grooves, O, are cut of width and length adapted to receivethe desired quantity'of bristles or other fiber or brush material. The bristles D are out long enough to be introduced in the head-stock doubled up, as shown, and to project therefrom to the desired 5 length.

E is a grooved core, made of a strip of tin, sheet-iron, or other suitable material, a little longer than the groove G in the head-stock, bent in U form. A portion of the back 01 40 core E, near each extremity, is cut away, so as to leave at each end of the strip two tongues,

a a, as shown in Fig. 6. The bristles D or other material are divided into bunches or parcels d, which are doubled over and arranged 4 5 along the back of the core E, being twisted at their centers at the same time. The first end bunches, e, are secured by the tongues'a a, which are bent back upon them in opposite directions, as shown clearly in Figs. 1 and 2. When the entire length of the bar E has been filled up, the bunches at that end are secured by the tongues a a. The filled core is then "forced into the groove 0, which is of size adapted to receive the core E and bristles D, preferably with some degree of tightness. Pins, rivets, or screws 7) b b are passed from side to side laterally through the headstock B, core E, and bristles D, thus securingall the parts firmly together. By this construction not only is the maximum of simplicity and strength attained, butthe necessity of piercing holes in the top of thehead-stock is avoided. The twist given to the center of each bunch of bristles fastens them more securely in the head-stock. The pins 1) b b passing through the bar E near 6 5 its ends and intermediately thereto impart great strength to the structure. The bending back of the ends a a. a a of the core E, re-enforced by the insertion into the groove 0, binds together the material and prevents the end' fibers from coming out or working loose. The core E by its construction presents a round-- ed smooth back or surface for the bristles to bear against, while it is far stiffer than a wire of equal thickness, and is better adapted to re- 7 5 ceive the fastening-pins b b I). This method of construction is applicable to brushes of any width or form. Any number of grooves of any shape may be made that the head stock will accommodate. One set of tastening-pins will answer for any number of grooves and rows of bristles. v 1

WVhat I claim as new, and desire to secure by Letters Patent, is

l. The brush composed of grooved head- 8 5 stock B, grooved core E, brush material D, and lateral pins 1) b in combination, substantially as shown and described.

2. The combination of core E, having oppositely-bent ends ad, with doubled and twisted bunches of fiber d d, head-stock B, having groove Qand pins 1) b, passing laterally through all these parts, substantially as shown and described.

3. The U-shaped core E, with tongues 51 a 5 a a bent back as a fastening-piece for bristles or other brush material, substantially as shown and described.
