PATENT OFFICE BRUSH William E. D. Turner, Portland, Oreg., asaignor to Turgard, Inc., Portland, 0reg., a corporation of Oregon- My invention relates to brushes, and more particularly to paste-spreading brushes, having the bristles thereof spaced for the reception of the paste to be spread when the same is forced ,to the ends of the bristles by pressure against the sides thereof.

People are now giving more attention to the preservation of their teeth. As a means toward the end they frequently brush their teeth using pastes and powders of various compositions and properties as aids in the cleansing operation. These cleansing operations usually take place in the home where the necessaries may be kept more conveniently, as it is not convenient to carry a brush and paste tube about on the person, when one is away from home, so that they may be used when and where needed. When people dine out they must frequently wait for hours or until they return home to clean their teeth. Again, many people, when away from home on a trip, either forget to take their brush and paste with them or find it inconvenient to do so.

It is my intention to dispense this article from slot machines placed in the rest rooms of hotels, restaurants, office buildings, department stores, recreation places, public comfort stations, oil stations, boats, and trains, so that, for a very small charge, a person may conveniently have at hand, when away from home, the means to cleanse his or her teeth.

An object of my invention is to provide a brush and sufi'icient paste. for a cleansing combined in such a form that they may be dispensed as a unit ready for use.

A still further object is to provide a cleansing unit of such small cost as to permit of its discard after once being used.

My invention lies particularly in the novel arrangement and construction of the cleansing unit the underlying principle of which is clearly illustrated in the accompanying drawing.

Thruout the drawing and specification similar numerals refer to similar parts.

Fig. 1 is a plan view of the one-piece blank from which the brush handle and the bristlesupporting structure is formed; Fig. 2 is an end view showing the blank formed as a U-shaped section; Fig. 3 is an end view showing the blank formed as a V-shaped section; Fig.4 is a perbristle-supporting structure and the bristles secured on the outer surface; Fig. 10 is a longitudinal vertical section thru a brush in which the paste is in a package provided with a rip-cord; Fig. 11 is a side view of a paste package having a short top-sealing flap opened by side pressure on the package.

In what I believe, at this time, to be the preferred form of my invention, the normally U-shaped section I shown in Fig. 2 includes the back portion 2 about which the sides 3 and 4 may hinge as shown by the dotted outlines 5 and 6. It is formed by folding the blank 1, shown in Fig. 1, along the creasing lines 8 and 9 respectively. The blank I may be cut or stamped from suitable flat sheet material such as a rather stiff, hardcalendered paper preferably prepared so as not to readily absorb moisture. Opposite the handle end ID of the blank I the sides 3 and 4 are widened out for a distance normally the length of the I brush ll formed of layers of bristles I2 of sufflcient thickness to give the desired body to the brush.

In Figs. 4, 5, 6, '7, 9 and 10, the bristles l2 are in one length suflilcient to extend beyond the edges 3A and 4A of the widened portions of the sides 3 and 4 to give the desired exposed length which approximates 55% of the bristle length adjacent either of the sides 3 and 4. The layers of bristles l2 are positioned intervening the sides 3 and 4 and are pasted, or sewn as shown by the stitching 13, to their inner faces 33 and 43 respectively.

A facing piece H of moisture resisting material is pasted over the top layer of the bristles l2. The width of the facing piece It being such as to bring its edges MA to the same plane as the edges 3A and 4A of the sides 3 and 4. Instead of pasting this facing piece M in place it also may be secured by the stitching l3.

Upon the facing piece I4 is placed the material to be spread by the bristles l2, such as the paste l5, which may be tooth paste. The paste l5 may be covered in one of several ways such as by a coating of paraflin l6 shown in Figs. 5, 6, 8 and 9. The object of this parafiin coating I6 is to hermetically seal the paste I5 so as to keep it in an unimpaired condition until ready for use.

The natural tendency of the sides 3 and 4 is to assume the position shown by the dotted outlines 5 and 6 of Fig. 2, especially after the bristles l2 are attached, and the paste l5 placed and sealed.

When it is desired to use the brush I I, the sides 3 and 4 are simultaneously pressed together between the thumb and forefinger of the user's hand (not shown) thus returning the sides 3 and 4 to their normally vertical position as shown in Fig. '7. As pressure is applied to the sides .3 and 4 and the faces IZA and i213 of the bristles i2 brought together, the paraflin cover it is broken and the paste i5 is forced upwardly be-- tween the faces HA and I23 to the top surface i2C of the bristles i2 ready for use.

In the form shown in Fig. 8, the layers of bristles i2 attached to the side 3 are separate from those attached to the side 4. The bristles l2 may thus be shorter or they may be long enough to be doubled back on themselves as illustrated. In all other respects the arrangement and construction, together with the operation, may be the same as heretofore set forth.

In the form shown in Fig. 9, the blank I is folded only once and that along the creasing line H, which is centrally positioned, thus forming the V-shaped section shown in Figs. 3 and 9. The bristles I! are shown in one length and are secured by the stitching I! to the outer faces 3C and 40 of the sides 3 and 4 respectively. The

facing piece I4 is eliminated and the paste II is placed between the diverging sides 3 and 4 and sealed by the paraflin It. The facing piece I4 is not necessary in this form of construction for it is primarily used to provide a more sanitary seal so therefore if the material of the blank i is non-absorbent it will suffice. In closing together the sides 3 and 4 to force the paste ll upwardly to the top surface I2Cof the bristles II their inner faces 33 and 43 will be brought together.

The facing piece I 4 may also be eliminated in all three of the forms above set forth by packaging the paste li as a means of hermetically sealing it in a sanitary manner. These packages may be formed in many different waysand opened in many difierent ways. In Fig. 10, I have shown ,a package l8 of non-absorbent material provided at its upper edge with a rip-cord I! one end ISA of which is securely pasted to the back portion 2 of the blank I. In Fig. 11 is shown a package l8, of non-absorbent material, which has a short sealing flap 20 adapted to yield ahead of the longer end flaps 2i when the paste it within the package it is put under pressure. When the paste it is sealed as in a package It the package should be pasted to one or both of the faces HA and MB of the bristles if, or to one or both of the inner faces 33 and 4B of the sides 3 and 4 respectively. The brush ii may be dispensed enclosed in an envelope which is not shown nor made part of my invention.

While I have described my invention as being used for a particular purpose and as taking a particular form, it will be understood that I may use it, for instance, as a paste comb, and that its various parts may be changed without departing from the basic principle and spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider myself at liberty to make such changes and alterations as fairly come within the scope of the appended claims. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: I

3. A brush being a one-piece blank having portions, constituting sides, separated by convergent fold creases, bristles secured to the outer faces of and extending beyond each of said sides, said sides being spaced apart to provide a spacing therebetween for the reception of the material to be spread by the bristles, said material being compelled to rise to the top of the bristles to position to be spread when the degree of spacing between the sides is decreased.

4. A paste-spreading brush having a bristlesupporting structure with opposed inwardly yieldable side portions, bristles secured to and movable with the side portions, a cavity formed therebetween when said side portions are outwardly extended,-for the'reception,of the paste, and means to hermetically seal the paste until ready 'touse.
