BRUSH.

Application filed December 9, 1921. Serial No. 521,987.

To all wit-m t may concern:

Be it known that I, ERNEST B. WRIGHT, a citizen of the United States, and resident of Upper Montclair, in the county o-f Essex and State of New Jersey, have invented certain new and useful Improvements in Brushes, of which the. following is a specification.

The invention relates to improvements in brushes, such as paint brushes. An object of the invention is the provision of an improved construction whereby a bridle is effectively supported and mounted in posi` tion, the bridle surrounding the b-unch of bristles to prevent undue spreading of the bristles while using the brush.

A. bridle is commonly secured in position below the ferrule'in which the upper end of the bunch of bristles is inserted, by providing it with upwardly extending arms which are secured to the outer` surface ofthe ferrule by nails or the like. My invention improves upon such constructions by secure ing or supporting the upwardly extending arms of the bridle to the upper end of the bunch of bristles within the ferrule. In the preferred construction the upper end of the bunch of bristles is embedded in a rubber composition or the like, which is then vulcanized, the arms of the bridlebeing secured to the vulcanized or cemented upper end portion of the bristles.

Other objects of the invention comprise the provision of improved details of construction and combinationsof parts, all as will be more fully set forth in the following specification and particularly pointed out in the appended claims.

In order that the invention may be more clearly understood attention is hereby directed to the accompanying drawings forming part of this application and illustrating one embodiment of the invention. ln the drawings Fig. l represents a side yelevation of a brush provided with the invention;

` Fig. 2 is a partial enlarged vertical section through the brush` shownQ in Fig. l;

Fig. 3 is a vertical section taken on line 3 3 of Fig. 2; and

Fig. 4 is a horizontal section taken on line 4-4 of Fig. l.

Referring to the drawings, the brush comprises a metal ferrule l into the upper end of which is inserted the head portion 2 of the handle 3. The bunch of bristles 4 has its upper end portion dipped into a soft rubber cement or similar material, or the cement material may, of course, be applied to theupper end of the bristles in any other suitablel way. This upper end portion of the bristles, indicated at 5, is inserted into the lower end of ferrule l.

The bridle 6` comprises a band preferably of thin sheet metal which is intended to surround the bristles a short distance below the ferrule, as is common. The bridle is provided with upwardly extending arms, 7, 7, the upper ends of which are secured to or supported by the cemented upper end portion 5 of the bristles.

When the cementing material has been applied to the upper end portion of the bristles, this end portion is inserted within ferrule l together with the upper ends of the arms 7 7, and the parts mentioned are then subjected to the usual vulcanizing process. The arms 7 may be provided with surfaces or portions adjacent the upper ends thereof which are specially formed and adapted to cooperate with the cementing material to secure the arms to the bristles. Thus, as shown in the drawings, the arms may be provided with perforations 8 through which the rubber will How and in which the rubber will harden during the vulcanization to secure the arms to the bristles. The upper end portions 9 of the arms are also shown as bent inwardly above the upper end portions 5 of the bristles, so that the bridle will be supported thereby after the rubber composition has hardened. It will be understood that the invention is not lim` ited to the joint use of` perforations S and bent ends 9, but that other means may be used for securing the arms to the cementing material.

After the vulcanizing of the rubber and the securing in place of the bridle, as stated, the head -portion 2 of handle 3 may be forced into ferrule 1 and the ferrule then secured tightly to the handle and the bristles, if this is necessary, in any suitable way as by pressing portions of the ferrule inwardly. When the ends of arm 7 are bent over, as shown at 9, the head 2 of the handle will be pushed into contact with these bent over ends 9 of the arms. The head 2 of thehandle being forced into the ferrule a determined distance in each instance, the position of the bridle 6 a desired distance below the ferrule will be automatically determined.

I preferably also employ a bent strip of metal l0 in place of vthe solid plug which is commonly positioned within the rubber dipped upper end o1- the bristles to provide a centrally disposed space within the bunch so as to render the bristles more pliable in use. The metal strip 10" is provided with a lower horizontal portion, the end portions et the strip extending upwardly and then outwardly, as is 'indicated at 1l, to form flanges which are supportedon the upper surface of the vulcanized endportion 5 of the bunch.

It should be understood that the invention is `not limited strictly to the details ot construction described but is as broad as is indicated by the accompanying claims.

Vhat l claimis:

l. in a brush the vcombination or" a ierrule, a bunch of bristles having the upper end portion thereoic embedded in hardened cementing material, extending into said ferrule, and a bridle surrounding the bristles and having rearwardly extending arms, said arms having portions thereotl extending into the interior otsaid terrule and cooperating with the cementing material to iixedly secure the arms to the cemented portion oi the bristles.

2. In a brush, 'the combination oit a terrule, a handle extending into the upper end of the same, a bunch of bristles extendingl into the lower end of the same, and a bridle surrounding the bristles below the ferrule and having arms extending into the iger-rule` ysaid arms having their upper end portions bent inwardly above the upper end portion ol the bristles, said upper end portion of the bristles being embedded in hardened. cementing material.

3. In a brush the combination of a ierrule, a bunch ot bristles having the upper end portion thereof embedded in hardened cementing material, and extendinginto said rerrule, and a bridle surrounding the bristles and having arms extending rearwardly into the interior of said ferrule, said arms having openings therein into which an integral portion of the cementing material. extends to iixedly secure the arms to the bristles.

Signed at New `York, in the county ot New York and State of New York this 6th day ot December A. D. 1921.

ERNEST B, lVRlGHT.
