This invention relates to certain new and useful nnprovements in dental brushes, commonly used with a dental engine by dentlsts for cleaning the teeth. It is customary ,to
use pumice or other polishing materialfor cleaning, and one ob ect of the present nvention is the retention of such pumice or other cleaning material within the brush during the cleaning operation; because of my-conm struction the cleaning ,material will not be thrown away from the brush by centrifugal force, as it might, otherwise be if only anordi nary brush were used. The brush will be more efficient in operation because the bristles will be maintained within. a small compass,
and consequently will have more stiffness than they would have if they were permitted to spread laterally. Another advantage'of my brush is that it may be sterilized easily,
and manufactured at such a low cost thatit may be discarded after use without entailing a heavy expense. i I
Another object is theproduction of a brush which is smaller in size, and thus is more readily usable in the human mouth, in that.
relatively inaccessible places'may be reached with greater ease andwithout the attending discomfiture to the patient which might be caused by the use of a larger brush.
The brush also has the advantage ofserv Fig. 2 is i VlQW, similar to Fig. 1,- with the V main brush portion shown in'section and the shank or stemshown 1n elevation; and i substantially on the line 3-3 of Fig. 2.
As illustrated in the above drawing, my device-comprises a metal shank or stem 5 anchored in the bore 6 of the brush socket or bristle holding member 7 Member 7 may be provided with a reduced portion 8 having an internal bore 9 which isadapted to hold se r curely the bristles 10." Around the bristles 10 may be "formed, awning oi; rubber 11 which'is' in liquid condition when" applied to the bristle; members but uponsolidifying ,;1 I forms. a very eflicient and tight engaging J sleeve to maintain the bristles within a small compass, "as before mentioned.
In applying the rubber'in itsliquid condi 1 ii tion it ofcourse will seat in'between the outermost bristles of the brush and will thus form a very effective bond between the rubber and i Q" the bristles because of theilarge surface with which the rubber thus comes in Contact 'rlativelyihmk a g v rubber may. be
used, ,or one which is less thick the thicker coating of course will give more strength and 4 rigidity to the brush.
' A resilient washer 12 maybe used onshan'k i i 5 in orderto reduce vibration and also to pro vide a somewhat more effective union between S the dental engine and thebrush member.
within the brush and willalso render;v the brush more rigid and hence more effective. s
While I have illustrated and described the I preferred form of construction for carrying my invention into effect, this, is capable of variation;andumodification iwithout departin from the spiritof theinvention. I,"- therefore do not wish to be limitedtovth y,
precise details of constructionflset' f0rth, but desire to avail myself of such variations and modifications ascome within the scopeof the appended claims; i
Having thus described invention,"what I claim as new and desireto'secure by Letters Y Patentis: a v v v i 1. A dental brush having a-shank, abr-ush, and bristles, said bristleshavingl a coat of rubber adhesively" embracing the outer bris- I s tles of. said'brush td-the free end ,of the Fig. 3 is a sectional viewof the brush, taken bristles.
2. Adental brush having a shank, a brush,;
andbristles, said bristles having a coat of. a
It can bereadily seenthat fthe coating 114; will assist in retaining the cleansing powder
