2 Claims. (Cl. 15-110) This invention relates to a combined tooth and gum brush and tongue scraper.

The object of the invention is to provide an instru ment which is adapted to be used by a person for brushing the teeth, massaging the gums, or scraping coating from the tongue.

Another object of the invention is to provide a combined toothbrush, tongue decoater, and gum massager whereby teeth, tongue and gums of a human being may be cleaned, scraped and massaged in order to promote better dental hygiene.

A further object of the invention is to provide a combined brush and scraper which is extremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same:

Figure 1 is a side elevational and sectional view of the present invention taken on the line ll-1 of Figure 2.

Figure 2 is a top plan view of the combined brush and scraper.

Figure 3 is a view similar to Figure 1, but showing the frame straddling the toothbrush instead of the gum massaging fingers.

Figure 4 is a perspective view of the present invent1on showing the scraper in an intermediate position.

Figure 5 is a sectional view taken on the line 55 of Figure 1.

Figure 6 is a sectional view taken on the line 6-6 of Figure 1.

Figure 7 is a perspective view showing the scraper blade.

Referring in detail to the drawings, the numeral it designates a bar or handle which may be fabricated of any suitable material, and extending from one end of the bar 10 and secured thereto is a plurality of bristles 11 which define a toothbrush. The other end of the bar 10 is provided with a recess 12, Figure 4, and seated in the recess 12 and secured to the bar 10 is a rubber pad 14. A plurality of spaced parallel rubber fingers extend from the pad 14 and are secured thereto, the fingers 15 adapted to be used for massaging the gums or other parts of the mouth.

Formed integral with the bar It) or secured thereto is a transversely extending rib 1.6. A frame 17 is pivotally connected to the rib 16, and the frame 17 includes a pair of spaced parallel legs 18 which straddle the bar 10, there being a pin 19 pivotally connecting the legs 18 of the frame 17 to the rib 16, Figure 5.

The frame 17 further includes a web portion 20 and States Patent 0 extending therefrom is a pair of spaced parallel arms 21, the arms 21 defining therebetween a space or opening for selectively receiving therein the bristles 11 or the fingers 15, Figures 1 and 3. Secured to the end of the arms 21 or formed integral therewith is a scraper blade 22 whereby any coating that may be on the tongue may be scraped or removed by means of the blade 22.

From the foregoing it is apparent that a single instrument has been provided which can be used for performing a plurality of operations. Thus, the bristles 11 can be used in the normal manner for brushing the teeth and during such use the frame 17 is pivoted to the position shown in Figure 1. Or, the rubber fingers 15 can be used for massaging the gums at which time the frame 17 is pivoted to the position shown in Figure 3. Or, the scraper blade 22 can be moved to an intermediate position as shown in Figure 4 so that the blade 22 can be used for scraping or removing coating from the tongue of the human being using the instrument. The bristles 11 may be made of any suitable material such as nylon or hair. By means of the present invention the teeth, tongue and gums of a human being can be cleaned, scraped and massaged as advocated by leading dental authorities. Also, the present invention can be economically constructed and will efliciently perform the previously enumerated functions.

We claim:

1. An oral instrument comprising an elongated bar, a plurality of bristles extending from one end of said bar and defining a toothbrush, the other end of said bar being provided with a recess, said bristles and recess being located in the same face of said bar, a pad seated in said recess and secured to said bar, a plurality of spaced parallel rubber massaging fingers extending from said pad and secured thereto, a transverse rib arranged intermediate the ends of said bar, a frame including a pair of spaced parallel legs, a pin pivotally connecting said legs to said rib, said pin lying in a plane parallel to said face, a pair of spaced parallel arms extending from said legs and defining therebetween an opening for selectively receiving said bristles or said rubber fingers, and a tapered scraper blade extending between said arms and secured thereto, said scraper blade being located adjacent and between the outer ends of the arms. I
