TQQTHBRUSH.

Application mea october e,

rluhis invention relates to a brush designed primarily for the orushing of teeth, although it may possibly be applied-advantageously to other uses as well. i

For its objects the invention aims to pro'- vide in an article of this kind three brushing units tw'o of which are associated yieldingly with each other, so that the three sets of brushes may operate simultaneously t clean the teeth upon their grinding surfaces and upon their contiguous inner and outer surfaces as well. It aims also to mount Athese several brushing units in a compact fstruct-ure with which is swivelly connected a handle by which the device in its entirety may be manipulated with ease. bjects such as these, as well as others which will hereinafter appearare realized froml my inyention, a suggestive embodiment whereof is illustrated in the accompanying drawing in lthe'manner following:

Figure 1 is a plan view of theibrush structure in its entirety;

Fig. 2 is a longitudinal section taken on line v2---2 of Fig. 1; and

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

In the present brush may be comprised a pair of backs 4 and 5 in which-are mounted bristles 6 and 7, respectively, and constituting two of thel brushing lunits. The two brush backs may each be inwardlyoifset as at 8 and then upwardly extended and brought together in the form of interlapping joints 9 through which is extended a hinge pin 10. I utilize also a third brush unit having a back 11 provided with joints 12 which' interlap the other joints 9. The hinge pin` 10 is extended also throughthe joints of this last unit in which are carried bristles 13. It will be noted that the ends of the bristles in this third unit terminate adjacent Ithe other sets of bristles 6 and 7 "which are extended toward veach other, as best shown in 7 Fig. Y Formed on the back 11 is a base 14 having a threadedisocket to receive a screw 15 which affords a swivel connection for a handle .16.

- By the means described the handle is free to i and 5 are further urged toward each other and toward the third back 11 as by means of i 192e. seriai no. 139,808. f

a wire Jspring 1 7, which may be coiled about vthe base 14 andA hinge pin 10 in such almanner as to present its opposite endswith pressure agalnst the.` two brush backs 4 and 5.

'The' back 11 thus forms a stop for the two backs 4 and 5. I

The brush of this invention is well adapted for o eration upon the teeth, as appears plainly 1n Fig. 3. When put to use, the

bristles 6 A.and 7 ,will engage with the inner and outer surfaces of the teeth while the other bristles 13 will' perform work upon the grinding' surfaces thereof. The brush inits entirety may be moved back and forth with the aid ofthe handle 16. lDue to the swiveled connection 15 the .device will turn in conformity with lthe curvature ofthe teeth as the brush is moved along the row of teeth l1n the mouth. As irregularities or variations occur in the'thickness of the teeth the two brush units 4 and 5 may yield, as required, the-ends of their bristles being held always in close contact with the` teeth due to the pressure exerted by the spring 17.

'lhe present brush maybe made of any suitable' material such as celluloid, bone,

vbakelite, metal, etc. The backs of its two units 4 and 5 may also be rounded in a 10ngitudinal direction, as shown in Fig. 1, so

as to better conform to the curvature of the teeth within the mouth. The' bristles are readily accessibleJfor cleaning, and'because o'f the sturdy construction employed, the

'brush may be depended upon to perform satisfactorily over an extended period of time. Iclaim: 1. A tooth brush having a pair of hingedly connected units with spring means tending to move them toward each-other, 'a third interposed unit hingedly connected with the others, and brush elements extending inwardly from each ot the three `units and terminating jadjacent each other to provide brushing surfacesadapted to operate simultaneously upon theA inner, outer, and grinding surfaces of the teeth, substantially as described.

2. A tooth brush having a pair of hingedly connected units with spring means tendv ing to move them toward each other, a third interposed unit hingedly connected with the others, brush elements extending inwardly from each of the three units and. terminating adjacent; each other to provide brushing surfaces adapted to. operate'simultanesurfaces of the teeth, and a handle having' ingA adjacent each other to provide brushfv -f ing surfaces ofA the teeth, substantia ly as ously upon the inner, outer, and grinding a swivel connection with one unit whereby the entire brush may be rotatively manipulated, substantially as described.

3. A tooth brush having a pair of hinged-l .ly connected units with spring means tending to movethem towardeach other, a third interposed unit hingedly connected with the others and stopping their inward movement,

andi brushing elements extending inwardly from each of the three units and terminating .surfaces adapted to operate simulta` neously upon the inner, outer, and inddescribed.

4. A tooth brush in which is combined a handle, a brush unit swivelly connected thereto, and a pair of other brush unitshingedly connected to each other and tothe unit, and

rst brush unit, each brush unit including cleaning elements terminating in three planes such as to adapt the device for operation upon inner, outer, and grinding surfaces of the teeth, and tension means urging th two opposite brush units toward each ot er, substantially as described.

5. A tooth brush in which is combined a. pair of hingedly connected brush units having bristles extended toward but 'stopping short of eachother, a third brush unit the brush units for manipulating the -olevice, substantially as described.
