BRUSH.

SPECIFICATION forming part of Letters Patent No. 445,649, dated February 3, 1891..

Application led .Tuly 3l, 1890. Serial No. 360,535. (No model.)

To all whom, it may concern:

Be it known that I, ROBERT W. HARDIE, a citizen of the United States, residing in Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

My invention relates to improvements in daubers having a brush-head consisting of a `the upper portion of the head-band so as to adapt it to the increased size of the upper end of the knot of bristles, due to the burred ends of the bristles or to the use of pitch, as hereinafter described, and in this manner cause the upper end of the knot to serve in effect as a wedge to hold itself firmly in the head-band.

A further object of my invention is to provide means for preventing the bristles from Working up out of place, and also for concealing the roughnessiof the top of the bristles, and to this endl placea cap upon the top of the knot of bristles; but the top of the knot isrough and uneven when left uncut,in order to utilizethe burred ends orpitch to help hold the bristles in place, as before mentioned, and the cap will not in such caserest evenly in place if supported by the upper end of the knot, and I therefore form the cap integral with a handle and secure the shank of the handle to a lateral extension formed on the headband, so that the cap will be supported in a level position irrespective of the condition of the top of the bristles.

In the drawings, Figure l is a perspective view of a brush embodying 1n y invention. Fig. 2 is a sectional perspective view of a knot of bristles inclosed within a head-band. Fig. 3 is a perspective view of a combined cap and handle detached from the head-band. Fig. i-.is a transverse section of said handle, taken on line 1 l of Fig. 3. Fig. 5 is a side elevation of a complete brush embodying a modification of my invention. Fig. 6 is a plan view of the head-band used in the construction illustrated in Fig. 5 with its arms separated. Fig. 7 is a plan view of the same head-band with its arms closed as when compressed to hold the knot of bristles.

In the construction illustrated in Figs. l to 4of thedrawings, A represents a knot of bristies inclosed Within a headband B. The diameter of the head-band is enlarged at its upper portion and contracted gradually downward, so that said upper portion will be adapted to conform to the increased size of the upper end of the knot of bristles caused by pitch or by the roughness of the bristles at that end, While the lower portion of the head-band grasps the bristles and holds the knot wedged in the head-band. Theheadband is provided with a lateral extension C, which is preferably made to project outward from the head-band in an inclined plane, as shown in Fig. 2. A cap D is placed on the top of the knot of bristles, and a handle E is formed integral with said cap. The shank e of the handle rests upon the lateral extension O of the head-band, and is secured to said extension by means of the rivets d, which pass through the perforations d in theshank of the handle and the corresponding' perforations c of the extension of the head-band. The brushis thereby provided with a cap which aids in preventing the bristles from working up out of place .and which conceals the unevenness of the upper end of the knot of bristles, and which also serves as a base for a label, and the handle is strengthened at its shank by means of the lateral extension of the head-band, whereas the handle Would otherwise be required to sustain the greatest strain at its weakest point. I prefer to curve the handle transversely, as shown in Fig. 4, and thus secure the greatest strength with the least weight of metal, although this is not essential to my invention.

Then the head-band is constructed .as illustrated in Fig. 2, the upper ends of the bristles should be coated with some adhesive substance-such as cement, pitch, or varnishand the knot then pressed firmly into the headband, the pointed ends of the bristles being preferably entered rst. The upper ends 0f IOO the bristles will then separate slightly by reason of the diameter of the head-band being greater at the top than at the bottom, and when the adhesive material hardens the upper end of the knot will be securely wedged in the head-band. I prefer in most instances, however, to construct the head-band in the manner shown in Figs. 5, 6, and 7. This headband F is constructed of compressible metal, such as malleable iron, and is in form an open ring, provided with laterally-projecting arms G, which are separated wheny first made, as shown in Fig. 6, but are adapted to be drawn together, so as to contract the innerarea of the head-band until it assumes the proportion indicated by the dotted circular line shown in Fig. 6.

The bristles are inserted in the head-band when it is open, as shown in Fig. 6, and the head-band is then compressed until one ofthe arms G overlap the other, as shown in Fig. 7, forming in eiect but a single lateral projection. Vhen the head-band is thus coinpressed, the bristles are pressed so tightly together that they are held in the headband Without Athe aid of any adhesive Substance.

A cap and handle similar to that shown in Fig. 3 is placed'on the knot of bristles when the arms of the headband are pressed together, the cap resting upon the top of the knot of bristles and the shank e of the handle resting on the extension Gof the headband. The shank of the handle is secured to the extension by means of rivets el', passed through the openings d of the shank and the corresponding openings g of the extension of the head-band. I Y

Then the parts are constructedV and arranged in the manner last described, the arms G perform a triple function. They not only serve as means for supporting the cap and securing it in place, but they also serve as means for holding the head-band compressed against the bristles, and they also strengthen the shank 'of the handle at its weakest point.

vVhat I claim isl. The combination, with a knot of bristles, ot' a head-handhaving its inner wall inclined upward and outward from the shortest diameter of the head-band, a cap placed upon the top of the bristles, and a handle formed integral with said cap and secured at its shank to a lateral extension formed on the headband, substantially as described, for the purpose specied.

2. The combination, with a knot of bristles, of a compressible head-band having its inner wall inclined upward and outward from the shortest diameter of the head-band, a cap placed upon the top of the bristles, and a handle formed integral with said cap and secured at its shank to a lateral extension consisting of two overlapping arms formed on the head-band, substantially as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.

ROBERT XV. HARDIE.
