Be it known that l, JOHN MORRISON, J r., a citizen of the United States` residing in Glens Falls, in the county of Varren and o State of New York, have invented certain new and useful lmprovements in Brushes, of which the following is a full, clear, and exa-ct description. My invention relates to brushes, and more lo particularly comprehends a hand brush ot small size and simple construction, and admitting of general use, but specially adapt-ed for 4service as a dauber for applying blacking, polishes and the like to shoes and other lo footwear. 1 seek to accomplish several distinct objects, hereinafter stated at length. Reference is made to the accompanying drawing forming a part of this specification, no and in which like reference characters indicate like parts throughout the several figures. Figure 1 is a substantially central longitudinal section through one form of my imga proved brush. Figure 2 is a view showing the brush partly in plan and as partly broken away, this fi ure also showing one form of my improve tie for strengthening the brush. Figure 3 is a fragmentary view showing the brush partly in plan and as partly broken away, this figure showing another form of my improved strengthening tie. Figure 4 is a View somewhat similar to Figure 3, but showing a construction from which the strengthening tie is omitted. Fig. 5 is a vertical sectional view through the form of device shown in Fig. 3. Figure 6 is a substantially central longitudinal section through a die and parts immediately associated therewith and used in the construction of the brush. Figure 7 is a fragmentary plan View of the die, with a brush handle extending thereinto and ready to be partially imbedded in making the brush. Figure 8 is a longitudinal section through the die shown in Figure 7, the brush handle being omitted. The handle 8 is formed of a single piece of stout spring wire, preferably steel, brass or aluminum. The wire is provided with end portions 9 and 10, bent toward each other and abutted together end to end. A tie 1l extends across the handle 8. and holds 1922. Serial No. 552,62. the two longitudinal portions thereof quite firmly. The tie in this instance is made up of a relatively small wire, wound tightly around the handle in a number of turns. The brush back appears at l2, and is made of moldable material; that is, material which is softened by heating and thereby rendered liquid or plastic, and which in this form can be poured into a mold. The bristle tufts appear at 13, and are at their upper ends securely embedded in the back 12. In the form shown in Figures 3 and 5, instead of the tie of the form above described l use a tie of the form indicated at la. rlhis tie is made from a bit of stout wire, and is provided with end portions 15 and 16, bent laterally from the general direction of the length of the tie. 1n other words the tie 14 as a whole has the general form of a wide and short staple. l't constitutes a bridge across the two oppositely disposed portions of the handle, and clamps or holds them in such position that the end portions 9 and 10 of the handle are forced rather tightly together and thus held with considerable firmness. The tie is located in such position that its end portions 15 and 16 are inclined relatively to the general longitudinal direction in which the handle eatends. ln the form shown in Figure t l do not use any tie, and thus rely entirely upon the inherent strength of the brush back 12 for the purpose of holding the handle 8. ln making the brush l use a die plate 19 provided with a mold wall Q() intergral with it, and together with it having the general proximate form of a cup. The wall 20 is approximately circular, as may be understood from Figure 7, and is provided with a pair of slots 21 through which the two oppositely disposed longitudinal members of the handle l8 may be thrust, as indicated in Figure 7. ln connection with the die plate 19 l use a. leveling pla-te 17, provided with a sink 18. 1n practice, iirst the bristles are assembled and arranged as to extend through holes in the die 19, and are brought int-o engagement with the adjacent depressedpor tion of the leveling plate 17 as indicated in Figure 8. This done, the die plate 19 is inverted, and placed upon the leveling plate 17, as indicated in Figure 7. The handle 8 'is next placed in position, as shown in this figure. n some instances I prefer to use the tie 11 shown in Figure 2, and in others I plrefer the tie 14 appearing in Figure 3. owever, I may use any other form of tie equivalent to either of these, or I may omit the tie altogether as indicated in Figure 7. The parts being arranged as dcscrilwd, the operator pours within the cup-like mold wall 20 a quantity of moldable material sufficient to fill the mold, and the moldable material is then-allowed to harden. This completes the brush, which is now simply lifted out and thus removed from the mold. It will be noted that the handle 8 has a very good anchorage Within the back 7 and that by aid of tie 11 or 14 the brush as a whole is rendered relatively strong. In practice, the greatest stresses to which abrush of the type here contemplated is subjected are those set up whenever, the use of the brush, the two longitudinal members of the handle 8 are squeezed together or pressed toward each other; also whenever these members are forced apart. The abuttinoP end portions 9, 10 prevent the longitu lnal members of the handle from being forced together in such manner as to readily break the brush back and the tie 11 or 14 is so positioned as to -prevent the two longitudinal members of the handle from being easily forced apart so as to fracture the brush back. Since the tie is completely imbedded within the brush back, it is thor oughly concealed. There is a co-relation between the abutting end portions 9, 10 and the tie 11 or 14. That is to say the tie 11 or 14, being under tension and thus held rather tightly in position uon the member 8, forces tightly together t e abutting end portions 9, 10; or, conversely, these end portions are so pressed against each other as to create a tension upon the tie 11 or 14, and thus to develop a certain amount of initial stress. By this co-action between the tie 11 or 14 and the abutting end portions 9, 10, the handle as a Whole 1s greatly strengthened in its anchorage within the back 12. For this reason the brush may be safely handled and used, if need be rather roughly, and withT out breaking. By the construction above described and particularly by useI of the tie 11 or 14, a relativelg chea grade of -moldable material mav e emp oyed in making the brushes, without substantial detriment to the quality of the brush. In this connection it should be noted that the initial stresses are so distributed and arranged that although -the handle necessarily exercises considerable leverage toward the brush back in many instances, such leverage is ordinarily unable to develop stresses adequate to fracture the brush back under conditions of normal use. The moldable material thus servcs'the double Ypurpose of a brush back end of holding together the individual bristles of each. tuft. I do not limit myself to the precise device shown, as variations may be made therein without -departing from my invention, the scope of which is commensurate with my claims. Having thus described my invention, what I claim as new and desired to secure by Letters Patent is as follows: 1. In a brush, the combination of a brush back made of molded material, bristle tufts carried by said brush back and each partially imbedded therein, and a handle made of wire and provided with a pair of end portions abutted together end to end and imbedded with said brush back. 2. In a brush, the combination of a brush back made of molded material, a plurality of bristle tufts carried by said brush back and each partially imbedded therein, and a handle made of spring wire and provided with-a pair of end portions bent toward each other and abutted together end to end, said end portions being imbedded within said brush back. 3. In a brush, the combination of a brush back made of molded material, a plurality of bristle tufts carried by said brush back and each partially imbedded therein, and a handle made of spring wire and provided with a pair of longitudinal members substantially parallel with each other and provided with end portions bent toward each other and fitted together end to end, said end portions being imbedded within said brush back. A 4. In a dauber brush, the combination of a brush back made of molded material, a plurality of bristle tufts each partially imbedded within said brush back, a handle provided with a pair of longitudinal members of spring wire disposed substantially parallel to each other and provided with end portions imbedded within said brush back and engaging each other therein, and a tie mounted upon said end portions and imbedded within said brush back. 5.
