5 Claims. (01, coo-2i) This invention appertains to brushes, and more particularly to tooth or like brushes. One of the primary objects of our invention is to provide a tooth brush which can be manusmall cost, whereby the brushes can be disposed of after one or two uses without placing an undue burden on the user.

Another salient object of our invention is to provide a tooth brush. which can be sold from coin-controlled dispensing machines placed at convenient points, whereby persons away from home can easily obtain and use the brushes.

A further important object of our invention is to provide a novel tooth brush having a water- With these and other objects in view, the in-' vention consists in the novel constuction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing: a

Figure 1 is a side elevational view of our brush,

parts of the view being shown broken away and in section.

Figure 2 is a top plan view of our improved brush.

Figure 3 is a longitudinal sectional view through the'brush, taken on the line 3-3 of Figure 1, looking in the direction of the arrows.

Figure 4 is an enlarged, detail, transverse, sectional view taken on the line H of Figure 3,

' looking in the direction of the arrows.

Figure 5v is a highly enlarged, detail, fragmentary, sectional view illustrating the coiled tubular paper handle.

Figure 6 is a transverse, sectional view taken on the line 6-6 of Figure 1, looking in the direction of the arrows.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter B generally indicates our novel brush, and the same includes a tubular handle l0.

In order to form an economical brush, the handle I is of a tubular construction and is paper or cardboard. Thus, the paper can be rolled in long sections and then cut into the desired handle lengths. In lieu of winding the paper spirally (as illustrated), the paper can be -factured and placed upon the market at a very rolled similar to a cigarette, as can be readily understood by those skilled in the art.

In order to form a rigid structure, the edge of the paper is beveled, as at l I, so'that a scarf Joint will be had. The forward end of the tubu-' 10 lar handle is slotted, as at l2, and the handle is compressed to form wings l3 and I4, between v which are positioned the brush bristles ii. The brush bristles I! can be secured between the wings I3 and I4 in any preferred manner, such 1 as by one or more wire staples IE, or one or more handle is adapted to receive dentifrice li't-The rivets. Use of thewire staple forms a convenient, -quick, and economical method of securing the bristles to the handle. a

As is clearly shown in Figures 1 and 3, the

an adhesive can be employed for securing the compressed part in position. The outer end of the handle can be closed by the use of a suitable stopper, or by compressing the handle, as at It. Glue or other adhesive canbe used for sealing the compressed part l8, as shown.

It is manifest that the dentifrice'may be supplied in any form; as, for example, a loose powder may be charged into the handle and sealed,

or the dentifrice may be in the form of a cartridgeor pencil and inserted into the hollow hantion of the water. This will prevent rapid de-- dle, it being understoodthat after it is inserted.

terioration of the handle during use and will, likewise, keep the dentifrice dry. Obviously, the

hollow handle can be waterproofed in various v manners, as is well understood by paper manufacturers. 'Thus, the fibers of the paper can be waterproofed during the making thereof, or the paper can be waterpro'ofed by being impregnated with suitable material, or the paper can be coated with. desirable substances, such as wax and the formed from a rolled, spirally coiled piece of like. Naturally, after the paper is rolled into the desired shape, the same can be waterproofed in any desired way.

Changes in details may be: made without departing from the spirit or the scope of our invention, but what we claim as new is:

1. The method of forming a tooth brush, which consists in first forming a section of paper into a tube; second, cutting the tube into desired lengths to form handles; third, slotting the forward ends of the tubular handles; fourth, placing brush bristles in the slot; and, fifth, compressing the sides of the slotted portion into contact with the bristles and extending a fastening member through the handles and bristles.

2. The method of forming a tooth brush, which consists in, first, spirally coiling a section of paper into a tube; second, cutting the tube into desired lengths to form handles; third, slotting the forward ends of the handles; fourth, placing brush bristles in the slot; fifth, compressing the sides of the slotted portion into contact with the bristles and extending a fastening member through the handle and bristles; and, sixth, sealing the handle in rear of the bristles to strengthen the handle and to define a chamber of the desired size therein. 3. The method of forming a tooth brush, which consists in, first, rolling a section of paper into a tube having waterproof qualities; second, cutting the tube into desired lengths to form handles; third, slotting the forward ends of the handles; fourth, placing brush bristles in th slot; and, fifth, extending a fastening member through the slotted portion of the handle and bristles and compressing the sides of the slotted portion into engagement with the bristles; and. sixth, compressing and. sealing the handle to form a chamber.

4. A tooth brush comprising, a waterproof, hollow, tubular handle having its forward end slotted longitudinally on one side, spaced parallel wings on the forward end of said handle on opposite sides of the slot, brush bristles disposed in the slot between said wings against the walls of the slot, a fastening element extending through the wings and the bristles clamping the wings together and the bristles in the handle, and compressed ribs on the tubular handle directly in rear of the wings, disposed in contacting relation, whereby to reinforce the handle and seal the handle from the bristle end of the brush.

5. A tooth brush comprising, a waterproof,

hollow, tubular handle having its forward end,

slotted longitudinally on one side, spaced parallel wings on the forward end of said handle on op posite sides of the slot, brush bristles disposed in the slot between said wings against the walls of the slot, a fastening element extending through the wings and the. bristles clamping the wings together and the bristles in the handle, compressed ribs on the tubular handle directly in rear of the wings, disposed in contacting relation, whereby to reinforce the handle and seal the handle from the br"stle end of the brush and form a chamber in said handle, a dentifrice in said chamber, and means sealing the outer end of the handle to close said chamber.
