ROBERT J. MONTGOMERY, OF CHICAGO, ILLINOIS.

BRUSH.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed May 24, 1912. Serial No. 699,453.

To all whom it may concern Be it known that I, ROBERT J. MONTGOMERY, a citizen of the United States, residing at Chicago, in the county of Cook, in the State of Illinois, have invented certain new and useful Improvements in Brushes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in brushes, nore especially brushes designed for toilet use, and has for its objects to produce a metal brush that will be very strong and durable and at the same time light in weight; that can be easily kept in a perfectly sanitary condition, and that can be economically constructed. I attain these objects by the means shown in the drawings and here inafter specifically described.

That which I believe to be new will besetforth in the claims.

In the drawings: Figure -1 is a top View of the brush; Fig. 2 is a bottom View thereof the brush bristles being omitted in both of these figures; Fig. 3 is a side elevation of the complete brush; Fig. 4 is a vertical central section through the handle portion and a part of the bristle-holding frame; the brush back or frame being partly broken away; Fig. 5 is a vertical cross-section, enlarged, through the brush; Fig. 5 is an enlarged detail being a bottom view of a portion of the back and handle and a portion of the bristle-holding frame; Fig. 6 is a perspective view of the lower member of the handle portion, the view showing the inner face thereof; Fig. 7 is a perspective view of the brush back or frame; Fig. 8 is a detail in cross-section taken at line 8-8 of Fig. l and illustrating the straightening means employed for joining the forward end of the lower handle member in place and connecting it with the rear end of the bristle-hold ing frame; Fig. 9 is a detail being a plan view of the front end of the brush and illustrating a slight modification in the construction of that end of the brush-back or frame; and Fig. 10 is a cross-section taken at line 10 10 of Fig. 9.

Referring to the several figures of the drawings in which corresponding parts are indicated by like reference characters 12 indicates a bristle-holding frame, best made of metal and, as shown, of open construction, that is, formed with a number of separated'longitudinal and transverse strips, in the lower faces of which strips are provided at regular intervals a series of hollow plugs in which are suitably secured bunches of bristles 13 as usual. This bristleholding frame, as a whole, is curved throughout its length from side to side, the convex surface being the lowermost, so that the bunches of bristles will be spread outward in the de sired manner, as best shown in Fig. 5.

14: indicates the brush-back or frame which, in the construction shown, is provided with a large opening therethrough so that when itis applied to the bristle-holding frame 12 it will rest only upon the side and end members of such frame 12 thereby leaving exposed practically all of said open bristleholding frame and. thus rendering it possible to run water through the brush for cleansing purposes without separating the bristle-holding frame and the brush-back. Such a frame as 14 is necessarily very light in construction and would, unless special means were taken to guard against injury, easily become dented or bent and present an unsightly appearance, and to prevent this I form it so that it is curved from side to side throughout its length to correspond to the similar curvature given to the bristle-holding back and thereby the two frames fit snugly against each other. Furthermore, to add strength to this brush-back or frame 14 I provide it with an upwardly struck head 15 which extends along the top of the frame at both sides, said side portions of the bead being connected, as clearly shown in Fig. 7, by curved bead portions at the ends, said curved portions being indicated by 15. The brush-back or frame 14 has its sides turned down against the side edges of the bristleholding frame 12, and it is held to the bristleholding frame 12 by a series of prongs 16 formed along the side edges of the frame 14:, the prongs referred to being turned inward so as to project slightly in between the outer rows of bristle-holding plugs (see Fig. 2). Such construction effectually holds the frames 12 and 14 together. Bending or curving the back or frame 14 so that it corresponds to the curvature of the frame 12 and fits snugly thereon, and providing such frame 12 with the beads 1515, enables the brush-back to be made of light, thin metal and yet be strong enough to maintain its shape even when subjected to rough usage. The forward edge of the brushback or frame 14 is to be flush with the forward edge of the bristle-holding frame ordinarily, but

if desired for the purpose of giving a different finish or appearanceto the brush such briish-back or frame 14: may be made slightly longer than the frame 12 and be turned down against the forward edge of such bristleholding frame, as illustrated in the modifi cation shown in Figs. 9 and 10.

17 indicates the upper portion of the brush-handle which, in the construction shown, is made integral with the brush-back or frame 141. The other or lower portion of the brush handle is indicated by 18, both portions 17 and 18 being so curved that when united along their edges in any suitable manner they will form a hollow handle.v

Now, a handle of thin metal is liable to be weak at the point. of juncture with the-body of-the brush unlessspecial provisionis made for strengthening the device and I have,l therefore, provided a constructionfor giving it needed strength, which strengthening means I will now describe.

19 indicates an upturned flange formed at the forward end ofthe lower handle-portion 18, such forward end and the flange thereon beingcurved from side to side to conform to the curvature of the rear end of the bristle holding back, such rear curved end of the bristle-holding back abutting against such curved flange. vided centrally with an opening ZOthrough which projects a short tongue 21 on the rear end of the bristle-holding frame and preferably formed integrally therewith, such tongue having, inthe form of construction shown, slightly inclined side edges so that 1t.

maybe wedged very tightly into the opening 20. Furthermore it will benoticed t-hat the upturned curved flange 19 does not extend outquite to the edges of the lower handlemember 18 thereby permitting theflange to fit snugly inbetween the downturn ed edges ing through the opening 20 and additional strength is imparted 'byreason-of the ends of said flange fitting snugly against the downturned edges of therear portion of the frame 14, such downturned edgesresting, as shown in Fig. 8, against the upper face of the handle-member 18.

The brush, as a-whole,:is light, strong and durable, due to the construction and arrangement of the parts, as ihereinbefore set :fortlnandican be easily kept-clean tby mun- This curved flange is probristle -ihold1ng frame ning water through the open bristle-holding frame, as will be readily understood.

"\Vhat "I claim as my invention and desire tosecure by Letters Patent is 1. In abrush, the combination with a bristle-holding frame having its upper face concaved so that its side edges are higher than its-central port-ion and having bristleholding plugs projecting from its under face, of a metal back curved from side to side and fitting over and upon said bristle- :holding frame with its edgeportions turned down against-ithesides ofthe said frame and provided with prongs that project between some of the said bristle-holdingplugs. V
