iTo: properlyacare-pfor the; teeth, it 1s.- essential t-hafl they:v bekept; clean;and' that proper circulation beyinaintainedinwthe gums.

drawings.
The accompanying drawings illustrate different practical embodiments of the invention, but the constructions therein shown are to be understood as illustrative, only, and not as defining the limits of the invention.
Figure 1is a central longitudinal section,
partly in elevation, of a device embodying the present invention.
Figure 3 is a central section perspective the line 2 -2 of of the clutch or chuck member, with a fragmerit of; the tool spindle: elevationi perr;

It willbe, noted from thistfigure that;t-he roll tapers to, its 'fre esend iandliis' of lessdiameter at its outer end. than .at its inner end. :Theipurposeiof this is )tlldt when the tool is manipulated ,in thecmoti th gneater pressure is desiredon theuteeth on gums; at

Theirol-l 2 isiiillustratedsas embodying. ,very
soft rubber sleeve 6, preferably: circumferen tially serrated or fluted and kfitted-iover a core of soft sponge rubber. 7,;which is, in .turn-secured to the stem 8 of the tool. The soft core 7 V will cooperated: to; form a pliable: and yieldablesbacking; :for the-soft. rubber; sleeve 6, so that; the latterwill inot be tooharsh on" the gums, ibut zwill n8XeItIhthBI 601l "w mild massaging teflect. LThe .tooluis: relatively long withrespect to its diameter in order to give ran effective area tof i operation and to I sovid istribute their: pressure uponxthe 1 gums and teeth thatudetrimental' abrasionuwill not resu1t;:lir o1n2 their use.
'In'-Figi1re-;1;i I have-shown a hand: piece embodying a tubular handle 9, through which extends the envelopelO of a flexible shaft 11. A chuck or clutch member 12 is secured to the end of the shaft and ,is driven therefrom. This member is in the form of a short cylindrical metallic block, the rear end of which is solid and in the forward-end of which is formed a hole 13 (see Fig. 3) of circular configuration. At
the base of the hole 13, a transverse cut 14 isformed in the block 12 and this cut extends substantially one half way through the block, so as to provide a fiat sided step 15 at the extreme end of'the hole 18. In
practice, the hole 13 may, if desired, have a slight taper, so that if the spindles 4 or 8 is slightly tapered and provided with a stepped end 16, as'shown in Figure 3, it may be forced into the hole. The stepped end 16 will then interfit with the step 15 vat the same time as the spindle becomes tightly seated in thehole and by this construction,
ios
the spindle is locked for rotation with the chuck. i
Associated with the hand piece is a guard 17 which in practice may be made of metal, celluloid or other suitable material. In Figures 1 and 2, the guard is shown as having a metal base 18, to which a non-metallic hood 19 is permanently secured. The base 18 of the guard is in the form of a substantially cylindrical split sleeve 20 adapted to be received into a correspondingly shaped pocket 21 in the end of the hand piece 9. If desired, the sleeve may have ;a bayonet joint and the hand piece a pin or the parts may be otherwise locked together to preclude relative rotation or inadvertent disengagement of the guard from the hand piece.
iBeyond the sleeve part 20, the guard is formed with the substantially semicylindrical hood. 19 which underlies substantially one half of the tool and the outer end of this hood is closed by an end wall'22 in the interior of which is formed a depression 23 coaxially with the tool so that the outer end' of the tool spindle may find a bearing in this depression, whereby the tool is not only steadied during its operation, but is precluded from inadvertent disengagement from the chuck.
In Figure 1, the tool is shown as cylindrical, but it may be tapered like a roll it desired.
As shown in Figures 1 and 2, the hood is preferably provided with an opening or slot 24c in its bottom andthrough this slot tooth ably removed so that the tool may be readily moved longitudinally, but when in assembled relation, the guard is always in place to. stabilize the tool and preclude contact of the backof the tool with the surfaces of the mouth.
1. A dental tool comprising a suitable spindle, a yielding core surrounding the spindle and a soft rubber sleeve embracing the core. 7 i
