` BRUSH.
Application filed January rIhis invention relates to brushes, and more particularly to bristle brushes;
An object of the invention is to produce a brush having many of the advantages of a pitch set brush; Y
A rfurther object is to produce a. brush in which the bristles are securely held tothe handle, and one that maybe produced in an Y economic and elhcient manner.
Heretofore among the many brushes that have been produced one of the most reliable has been the so called pitch set brush which is comparatively expensive. Thisis a brush wherein separate individual units of bristles were each positioned in a hole in the base of the brush and heldv therein by suitable means inafter described in reference to certain pre-v such as a plastic.
In accordance with my invention a brush i is produced which possesses many of the advantages of this type of brush,` but is free from the objections of the older type.: Y
Briefly stated the brush in its preferred form comprises a bunch of bristles surrounded at one end by a member whose interior is f provided with a plurality of grooves substantially parallel to the bristles, and the bristles are preferably impregnated at this Vend with-a plastic. An expanding member is positioned in the bunch of bristles at the impregnatedend and serves to force the bristles outwardly toward this encircling member andto force portionsof thebunch of bristles into the interior grooves formed in the encircling member, thereby causing the bristles to be held in place not only by the plastic but-additionally by the clamping action between the expanding member and theencircling member.
Those portions ofthe bunch of bristles 1 forced into the grooves are'formed intoismall units, which stand out from the bunchof bristles, presenting thereby a serrated surface adjacent the encircling member. These serrations act as key members to firmly lock the'. bristles in position.
The inventionconsists in the product hereferred embodiments thereof, and the Vinvention will be more particularlypointed out in the appended claims.
In the drawings Fig. 1 is a side elevation showing parts of the brush at one step of manufacture.
Fig. 2 is an end elevation of Fig. l.
1e, 1925., sei-iai No. 2.789.
' side elevation with parts broken away.
Fig. l0 is a sectionat 10-10 of Fig. 9. Referring to the drawings, and more particularly to Figs. l\-(f; first I take a suitable quantity of loose bristles, which may beV gauged such as by weighing7 and arrange them into a bunch 1".;(Figsfl and 2) that w1ll beofsuliicicnt'size forl the brush to be inade. I next surround -thebunch of bristles,l
a point intermediate` its ends,vwith` an en-v circling member or band 2 made of any suit-v able material or materials, such for example as wood, metal, composition orthe. like pro! vided with grooves 3 (Figs. 55 6 .and ,10)
which extend in a direction substantially' parallel to the bristles.Y lVith theencircling member 2 slipped back from one end of the bristles'a distance greater than the height ofthe member 2, this end of the bunch lis dipped in suitable plastic such as rubber a depthl preferably substantially equal tothe heightl of the member 2; forming' thereby .anv impregnated portion designated (Figs.v I and 2) as 4L. Those portions ofV the bristles so coated will be termed the roots" of the bristles. By suitable' means7 suchfas a drying oven, the end l is partially solidified by having a part of the solvent driven off.
With a suitable instrument such as the cleaving knife 5 thisplastic-impregnated endv of the bunch is now separated lengthwise of the impregnated end and in the cleft so former the expanding bristle-member or wedge (6 is inserted and the lknife 5 withdrawn The CII impregnated end 4, :with the expanding.v I member 6 in posit-ion 1s` nowv placed in a suitable die` (not .'sho'wn) and this end is pressed to the desired sizeand shape so that the memberA 2 may be forcedaround it. Thel encircling member 2 is now forced up until it surrounds the dipped endl and expanding member 6to therebygforce exterior portions of the bunch of bristles into the grooves 3 and thereby firmly lockor key the outerl bristles in a fiXedstablel` position within these grooves; while all of the bristles are firmly squeezed 1n between the encircling member 2 and the expanding member 6, such Vas at 7. The brush so tar formed is now 7) 8. The handle 8 is provided with a recess CII formed within the dependingV sleeve 9. This recess has an inside contour adapted to receive the encircling member 2 which carries `the root end ot the bristles and the wedge 6 united therewith by means ot lthev plastic binder. The united end ot the bristles is now insertedV in this recess as shown in l' Fig. 7, and is secured therein by any, suitable means such for example as by the nails or screws lO. In additi-on to this means of fastening, or in place thereof fastening means suchas screws or nailsfll may be inserted through the member 6 into the handle 8. In either event the bristle unit will be firmly held tothe handle.
Instead of a single wedge or expanding member 6 asshown in Figs. l, 2, 3, 4, 5, 7, and 8 it will be obvious that two members such as 6 and 6 may be used as 'shown in FigsG, 9 and l0. Also instead of formingthe encirclingmembertrom ,one piece ot wood or other material it may be made as shown in Fig. 10 ot two or more pieces 2 and 2 joined together by suitable means such as a metal stripor band 2 and when so made instead of inserting the bristles through the member so formed, the member may be assembled'about the bristles it desired. in this case the handle 8 is notirecessed but is provided with a reduced portion 9 over which the band 2 will tit and to which it 'is then attached by suitable means 'such as nails or screws 10, it being understood that the band 2 in this case is of greater width than the depth of the members 2 and 2". Also where one member such as 2 is used a band similar to 2 may be used to attach the tutt unit to a handle such as the handle 8.
By this method ra brush is produced in which the bristles are irmly held and will not shed. In addition to the plastic binder the expanding wedge member 6 holds the bristles firmly outwardly pressed against the encircling member 2 and added to this the grooved portions in which a portion ot the Vouter bristles `are Vseated form individual pockets or recesses in which small units ot bristles are firmly held, thus imparting addimsss Y Y. .l
ed strength to the bristle unit. These serrated portions of the bunch which are formed in the interior grooves ot the member 2 prevent the sidewise movement of the bristles and by being divided into smaller units with interposed portions ot the member 2 the expansion and contractionot the plastic is accommodated or permitted by the yield ot the member 2.
Having thus described my invention with particularity with reference to certain preferred forms thereof, it will be obvious t0 those skilled in the art, att-er understanding myinvention, that other changes and modi- Iications may be made therein without departing from the spirit and scope ot the invention; and l aim in the appended claims to cover such changes and modications as are within the spirit and scope of the invention.
`What I claim is: Y
'1. A bristle brush comprising an oblong band member embracingand securing, the butt end ot' a. bunch of bristles, said band being provided interiorly at least along its longer sides with a plurality of substantially semi-circular spaced grooves running substantially parallelto the bristles, the diameter ot' said grooves being small with respect to the 'width of the brush, a core disposed within said butt end of the bunch ot bristles and running lengthwise of said oblong band, said bunch ot bristles comprising one undivided c'ontinuous tutt cemented and permanently formed in sit-u under pressure of said core, the periphery of the bunch of bristles being firmly secured and also serratedV by reason ot said grooves, and a handle having means tor engaging said band member.
2. bristle brush comprising an oblong band member embracing and securing` the buttV end ot a bunch of bristles, said band being provided around its interior surfaces with a plurality or" spaced grooves runningv substantially parallel to the bristles, said grooves being-intercepted byblunt surface? areas, a coredisposed within said butt end of the bunch ot bristles and running lengthwise Vwithin said oblongband, said bunch of bristles comprising VanV integral tutt filling said band and cemented and permanently formed in situ under pressure ot'said core, the periphery of said tutt beingV iirmly secured and also formed with spaced ridges by reason ot said spaced grooves, anda handle member secured to said band member. Y,
In testimony whereof have signed my name to this .-speciiication. Y
