Application fried February my iiivention is to which tlie contour of of the tufts may be my invention is to provide for the ready .renioval of any of the self-contained groups of tufts aiid the replacement thereof after wear to groups possessing Still another objec whereby the groups ranged or a. change a different quality.

t is to provide a means of. tufts may be arin other than an unbroken line for tlie purpose of avoiding obstacles. Still further objects of my invention are to provide a device for tlie purpose aintended which is si rugged, easy to oper get out of order.

In the drawings, a by way of example, bodiments of the inv Fig. l is a side View inple to manufacture, ate and which will not cconipanying, is shown, one of tlie possible emention:

of the device showing tlie tufts grouped to form a concave coiitour.

Fig. 2 is a plan moved,` showing the mechanism.

View with brushes replan of the operating Fig. 3iis a side View of the device showing the tufts grouped to 4form a convex contour.

Fig. 4 is a cross sec tion View of the brushes taken on line ara-w, Fig. l.

Fig. 5 is an enlarged cross-section view of the holder with brushes removed taken on line @F /J, Fig. 3. My improved device consists of a handle l of suitable inaterial,

such as aluiniiium,

with a tubular end portion 2, v'fiattened and widened, if required, at the brush end of the handle.

Mounted on the said brusliend 2 are channels 3 with inwardly bent edges or legs ,4. Tlie said channels are secured,

through openings 5, disks or wlieels 6, a toothed idler 7.

secured in ak composition, such as celluloid. inserts snugly into and through being held therein frictionally,

inwardly bent edges cured to the handle or octagonal, as pref Fig. 2, to the toothed said disks engaging withV The brushes 8 prefer-v ofrows of tufts ofbristles 9, base 10 vmade from suitable Said base channel 3 and by the 3'may be rigidly seerred; the said lbase behexagonal,

ing providedfon the top edge of every side with-a recess whereby to engage a corresponding projection, selectively placed oii sides 4 of channell.

VVhen used asa tooth brush, it is obvious that the brushes may be arranged to clean the outside ofthe teeth (Fig. 1); to clean the inside (Fig. 3); or, as in (Fig. 2) to cleanse the outer and inner parts of a plate for artificial teeth.

VVhile a specific application of the inveiition is herein described, the invention is not limited to this since the device may be adapted to many and various uses without departing from the scope of the invention, as claimed. i

I claini: i

1. The combination of a handle having an end portion providing a supporting means, a pair of members rotatably mounted on said end portion, each member being provided with a row of bristle tufts, said tufts being graduated in lengths from one end to the other of the member whereby said member inay be rotated to effect a brushing surface ofconcave or convex contour.

2. A tooth brush consisting of a handle Vflattened and liollowed, a pair of toothed dislrsspaced apart in said hollow portion, a toothed idlerdisposed in saidV lliollowportioii between the ldisks and engaging both the disks, mounts attached to said disks for rotationtherewith. and means on each of thereon eiid for end, each member carrying` a row of bristles graduated from end to end thereby forming deep, and shallow ends, whereby when the shallow endsare adjacent a yconcaved "biushing surface is formed and when the deep endsare adjacent a conveXed brushing surface is formed.

4. In a tooth brush, the combination of a support; a pair of members reversibly mounted oii said support and each reversible thereon end for end, each'finember` carrying a row of bristles graduated from end to end thereby forming ends.

5. lIn atooth brush, the combinationof a handle ;provided with a supporting means;
