This invention relate to brushes commonly in the provision of an expendable brush element comprised of a block of paper adapted to be folded intermediate its length and turned back upon itself to provide. in that one operation an enlargement for insertion in and retention by a holder and oppositely tapering surfaces at the working edge of th brush.
.Another object of the invention isthe provision of-a brush element comprised of .a block of paper which may be-slit through its full depth atintervals throughout its width to provide a plurality ofstrands.
A further object of the invention lies in the provision of a brush element comprised of a block of paper shaped to provide a working edge having oppositely tapering surfaces and a retaining edge of enlarged-dimensions.
The foregoing and other and more specific objects of the invention are attained by the arrangement illustrated in the accompanying drawings, in which Fig. 1 is a general perspective View of a retainer, including a handle adapted to receive a removable brush filler element whichmay be inserted. therein and designed toexert a clamping action on the filler, and including an open channel-shaped way having arestricted throat defined brush filler element comprised of a. plurality of sheets of paper in the .form of a block folded over at the middle to provide an enlarged tubular portion adapted to be inserted into the retainer and to taper the working edge in opposite directions, and illustrating fastenings adjacent the enlarged retaining portion for maintaining theassembly of the block,v and illustrating through slits atin'tervals across the width of the element providing a plurality of strands;
"Fig. 3 is a general perspective viewof the brush element and retainer handle showing them 'inpartially assembled relation illustrating th method of assembling the part by inserting the enlarged retaining portion of the Jfiller element into the open channel-shaped retainer through one end thereo'f'and sliding it intoiposition against the frictional resistance offered vbythe clampingac tion' of 'theffl'anges vcomprising "the channel";

Fig. '7 .a detail perspectiveview also of the pad "of paper "illustrated in Fig. 6, during thefolth l ng operation, illustrating "the manner of automatically providing the oppositely tapering surfaces of the working edge of the brush by the folding of a pad of equal sized sheets of paper intermediatethei'r length; and
Fig. :8 also "is ."a detail perspective view of the completed block of paper, comprised of thepad illustratedzin Figs. "6 and "7 folded. back'upon itself and secured by through fastenings adjacent the folded portion defining: "the enlargement for"in-' sertioniinto the holder, with the oppositely'tapering surfaces of thework'ing edger disposed upright.
The invention contemplates a brush having "a renewable filler :brush "element which makes feas'ible a permanent "holder having a disposable brush portion which may economically be discarded after each use and replaced bya n'ewfiller" element. In the drawings, l0 represents a brush holder of relativel permanent nature, having an upright handle 11 and including a generally (than: ne'l-shaped brush retainer portion l2. The re ta'iner 1'2 is formed on a radius terminating in oppositely disposed flanges 1 3. 'The fiangesaare each formed on a compound curve providing a restricted throat and a flaring mouth opening downwardly. 'Theway provided by the channel'- shaped retainer is open at both ends to permit,
full utilization of the flexibility of the flanges I3 throughout the full length of the retainer, frictlonally to engage and grip a removable brush element hereinafter to be described. The channel way may be of any length desired, depending upon the size of the brush to be provided, and while an upright handle has been provided in the form illustrated, any ype of handle necessary to any particular form of brush may be provided, as desired, or the handle might be made removable if preferred.
The retainer I2 is designed to receive and closely embrace a removable brush element I5 which, in accordance with the invention, is of a particular form comprised of a material enabling manufacture of the brush as a disposable refill unit for the holder at a cost which would justify the economy of such an arrangement. As shown 1 in Figs. 2, 3 and 4, the brush I5 comprises a block of paper secured by fastenings I6 and having an enlarged end portion I1 adapted to be engaged within the retainer, I2. The working edge of the brush is provided with oppositely tapering surfaces I8 to facilitate the application of material to a surface being treated. A plurality of regularly spaced vertical slits I9'extending through the full thickness of the brush may be disposed substantially throughout the area thereof to dividethe brush into a plurality of strands 20.
The block of paper I5 preferably is assembled with the holder I by slidably inserting the enlarged end portion ll of the block into the channel-shaped way I2, as shown in Fig. 3, and sliding it axially to the fully enclosed position indicated in Fig. 4, against the friction created by the clamping action of the flanges I3, which retains the brush element in operative position although the block might be snappedinto position by forcing it between the flanges against the spring action thereof. Thus assembled, the brush may be used for any purpose desired and then, if necessary, the filler element may be removed by sliding it through either end, and discarded, to be replaced by a new filler for subsequent operatlons. The economy of the paper filler element makes feasible the full utilization of this disposable feature and frequent replacement by a new element as necessitated by the various types of work for which the brush may be used.
The paper block I is comprised of a plurality of sheets of paper of a flexible or pliable nature and which may be stacked in the form' of a flat pad 2|, as shown in Fig. 6, and cut to the desired size as necessitated by the size of the brush element required to provide the desired flexibility in the brush necessary to proper spreading out and working of the fluid materials with which the brush is designed to be used, such as the application of paints, varnish, glue or the like to wood or metal surfaces or in the general application of liquid materials to any type of surface. The pad may be slotted, as indicated, at opposite sides of the mid-portion in this one cutting operation if the slits I9 are to be provided in the finished article. The individual paper sheets comprising the pad are all cut to the same size, and as a consequence, the folding of the pad about the unslotted mid-portion, as shown in Fig. 7, causes a tapering of the opposite extremities of the pad as it is folded to provide the oppositely tapering surfaces I8 at the working edge of the brush in the completed assembly, as illustrated in Fig. 8. Fig. 7 shows the pad of paper 2| partially folded, while Fig. 8: shows it completely rebent upon itself to provide the block of paper comprising the renewable brush. The finished state of the brush element is maintained by then inserting staples I6 through the combined thicknesses of the folded pad adjacent to the intermediate folded portion, and this location of the securing means defines the enlargement I! for confinement in the holder. The folding of the pad and the attachment of fastening means adjacent thereto forms a substantially tubular enlarged end portion Well adapted to axial insertion into the open channel-shaped way of the retainer and for retention in the restricted throat therebetween, held firmly in operative position by the pressure exerted through the flexibility of the retaining flanges. The length of the sheets of paper from which the block is formed is such as to afford suflicient length in the finished brush element in proportion to its thickness to provide ample flexibility of the brush in spreading and working out the materials with which it is used.
The block of paper comprising the brush filler element may be fabricated as shown in Fig. 5 if desired. In this arrangement, plain sheets of paper are utilized to provide a block of paper 25, secured adjacent one edge by staples 26 to provide an integrated assembly adapted for insertion into a holder in the same manner as that previously described. A wedge-shaped core member 21, which also might be of paper, may be secured in the block at the stapled edge to provide a well defined enlarged edge portion for positive engagement within the retaining member. As shown, the brush is provided with oppositely tapering surfaces 28 at the working edge, as in the previous form described. In the form shown in Fig. 5, th plain paper sheets afford a brush well adapted to the even application of materials to a surface without streaking, and in all forms the oppositely tapering working edges provide capillary surfaces functioning efliciently to take up and retain the materials used for application to the surface being worked.
From the foregoing, it will be seen that a brush has been provided wherein a relatively permanent holder may be equipped with a replaceable brush which may be renewed indefinitely, and which is comprised of paper for disposability, and of simple formation capable of ready and economical manufacture for low cost distribution.
What is claimed is:
1. A brush for the application of liquid materials required to be Worked and spread out over a surface to be coated including an elongated channel shaped holder having a handle extending from the rear thereof substantially midway along the length thereof and a separate brush element mounted in the holder and removable therefrom for renewability, said brush element consisting of a plurality of sheets of paper all of substantially the same length folded in the center and rebent to provide a pad including a flat portion having a working length in proportion to its thickness'providing flexibility in the flat portion affording the pliancy thereof necessary to said working and spreading of said materials and terminating in a free edge of V-shape in cross section and having an enlarged tubular portion at the fold, and fastening means securing said sheets together between the tubular and flat portions, said tubular portion being mounted in the channel of said holder.
2. A brush as claimed in claim 1, in which the sheets of paper are slitted lengthwise in the fiat 5 portion only of the pad to divide the sheets into a plurality of strands which are held together by the unslitted portions of the sheets in the tubular portion of the pad and by the fastening means.
