Application November 2, 1931. Serial No. 572,555

6 Claims. (Cl. 15-167) This invention relates to a tooth brush and particularly to a tooth brush which employs both hog's hair bristles and rubber bristles.

Practically all tooth brushes in use today em- 6 ploy hog's hair bristles for the purpose of cleansing the teeth. Many years of careful observation has determined that the ordinary tooth brush as used causes detrimental wearing away of the teeth, the gum tissue, the peridental meml brane, and the bony structure investing the teeth; the greatest harm from'such wear being the destruction of the gum ligament which is attached to the necks of the teeth as this causes recession of the gum and a predisposition to pyorrhea. In fact, many cases have been observed where the abrasive action of an ordinary tooth brush has been so great as to practically cut through the thin enamel adjacent the necks of the teeth, thus rendering the teeth very sensitive.

The object of the present invention is to provide a tooth brush whereby detrimental wear to teeth, gums, etc., may be substantially eliminated; to provide a tooth brush in which hog's hair bristles and rubber bristles are so combined that the teeth may be thoroughly brushed and cleansed without injurious wear to the adjacent tissue; to provide a tooth brush whereby the gums may be massaged and the teeth brushed simultaneously; and further, to provide a tooth brush which is so shaped that both the inner and outer surfaces of the teeth may be efllciently brushed.

The tooth brush is shown by way of illustration in the accompanying drawing, in which Fig. 1 is a side elevation of the brush. I

Fig. 2 is a plan view of the same.

Fig. 3 is a cross section taken on line III-III of Fig. 2.

Fig. 4 is an enlarged perspective view Mom of the rubber bristles.

Referring to the drawing in detail A indicates the handle and B the head of a tooth brush. Suitably secured in the head are rows of hog's 4 hair bristles c and rubber bristles D and E. The hair bristles extend from end to end of the head and are preferably arranged in cross rows with the opposite end of each cross row pointed as indicated at 22, this being an important feature as it permits the bristles to readily enter the spaces between the teeth when brushing the same. The rubber bristles are preferably arranged in longitudinal rows, one row on each side of the head. This is also important as they partially shield the hair bristles and in this manner protect the gums against the abrasive action of the same and they furthermore provide a means whereby the gums will be subjected to a massaging action when the teeth are being brushed.

The shape or,construction of the rubber 'bristles is best shown in Figs. 2 and 4. From these views it will be noted that the upper ends of the rubber bristles are wedge-shaped as indicated at 3 to permit them to pass freely between the teeth, and also to permit thehair bristles to follow through. The exterior surfaces of the rubberbristles are corrugated or serrated as shown at 4 and as such form an undulating surface ideal for massaging the gums. The rear surfaces of the rubber bristles are rounded as indicated at 5 to permit free flexing or bending of the hair bristles in a direction lateral of the brush and the point and heel of the brush is left open as indicated at 6 and 7 to permit free movement of the bristles in a longitudinal direction. This is 7 of further importance especially as it allows the bristles at the forward end of the brush to cleanse the inner surface of. the front teeth.

By referring to Figs. 1 and 3, it will be noted that the hair bristles are considerably longer than the protecting rubber bristles. This forms an elevated abrasive surface for the cleansing of the teeth and at the same time permits free movement of the bristles when brushing.

In actual practice the tooth brush is preferably 95 manipulated as follows: If the lower teeth are to be brushed first, the head of the brush with the bristles pointed downwardly is introduced between the cheek and the outer surface of the teeth. In this position the rubber bristles will rest against the gum portion below the necks of the teeth and as such will protect the gums against the abrasive action of the hair bristles. The handle of the brush is then rotated or rocked about its longitudinal axis by means of the hand approximately one-half revolution and during such rotation or rocking movement the rubber bristles will rub and massage the gums in an upward direction and the longer hair bristles will brush over the outer surfaces of the teeth and will also enter the intervening spaces between the same; the brushing action being in the direction of the longitudinal axis of the teeth rather than crosswise of the teeth as is-common practice.

This rotational or rocking movement of thebrush is repeated a sufilcient number of times until the surfaces of the teeth are thoroughly cleansed and all deleterious particles of food, etc., are removed from between the teeth. The upper teeth are brushed in the same manner, the only difference being that the position of the brush head is reversed so that the bristles will point upwardly; it being understood that both the inner and outer surfaces of the teeth must be-brushed in the same manner if the teeth are to be thoroughly cleansed.

The cleansing eiilciency of a tooth brush is dependent upon the hog bristles. When rubber is wetand tooth paste or powder is used, the rubber bristles slide over the gums and the teeth and perform comparatively little, if any, of the cleansing operation. They do, however, protect the gums as they are interposed between the gums and the hair bristles, but as the hair bristles are longer and, as the brush head is being rotated, the hair bristles will sweep over the surfaces of the teeth and will also pass between the teeth, thus insuring the cleansing action desired. The preferable method, as described, is that of imparting a rocking or rotational movement to the brush, or in other words to brush the teeth in an up and down direction. The brush here illustrated is, of course, particularly intended for that purpose, but if a person brushes his or her teeth in the usual manner by pulling the brush back and forth across the teeth, the brush here shown will be better than the ordinary brush as the hair bristles will still sweep over the surfaces of the teeth while the exterior rows of rubber bristles will engage the gums and to that extent protect the same.

The arrangement of the rubber bristles exterior of the hair bristles and at each side thereof is accordingly exceedingly important as it forms a protection for the tender gum tissue at the necks of the teeth and also the gum tissue in the interdental spaces. Furthermore, the gums will receive a certain amount of massage action and this is desirable as it promotescirculation and furthermore hardens the gums.

While certain features of the present invention are more or less specifically described, we wish it understood that various changes may be resorted to within the scope of the appended claims. Similarly, that the materials and finish of the several parts employed may be such as the manufacturer may decide, or varying conditions or uses may demand.

Having thus described our invention, what we claim and desire to secure by Letters Patent is- 1. In a tooth brush an elongated head member, a pair of rows of rubber bristles extending substantially from end to end of the head, one row on each side thereof, and rows of hair bristles extending crosswise of the head intermediate the rows of rubber bristles, said hair bristles being of greater length than the rubber bristles and forming an abrasive surface which is elevated with relation to the ends of the rubber bristles and having one rubber bristle for each cross row of hair bristles, and said rubber bristles aligning with the cross rows of hair bristles.

2. In a tooth brush an elongated head member, a plurality of rows of hair bristles extending from end to end of the head and arranged crosswise thereof, each end of each cross row terminating in a point, a pair of rows of rubber bristles extending substantially from end to end of the head, one row on each side of the rows of hair bristles, the upper ends of said rubber bristles being wedge-shaped, and'corrugations formed in the outer faces of said rubber bristles.

3. In a tooth brush an elongated head member, a pair of rows of rubber bristles extending substantially from end to end of the head, one row on each side thereof, rows of hair bristles intermediate the rows of rubber bristles, said hair bristles being of greater length than the rubber bristles and forming an abrasive surface which is elevated with relation to the ends of the rubber bristles, and said rubber bristles being substantially wedge-shaped at their upper ends and their outer faces being provided with corrugations.

4. In a tooth brush having hair bristles arranged throughout an elongated area, and a row of rubber bristles on each side thereof, said rubber bristles having their surfaces toward the hair bristles curved to permit flexing and having relatively flat corrugated outer surfaces with which to massage the gums.

5. In a tooth brush having hair bristles, a row of resilient bristles disposed on each side thereof, and corrugations formed in the exterior surfaces of the resilient bristles.

6. In a tooth brush having an elongated head, rows of hair bristles extending from end to end thereof, and a row of rubber bristles on each side of the hair bristles to cover the exterior side rows of hair bristles, said rows of rubber bristles terminating short of one end of the rows of hair bristles to expose a tuft of hair bristles at the outer end of the head.
