' HENRYBARNES, OFCLEVELAND, OHIO.`

TOOTH-BRUSH.

Specification of Letterslatent. i Patented Apr. 22, 1913.

Application led Deccmber23,`1911. Serial No. 867,423.

To all 'whom/t mary concern Be it fknown that `I, Harzer` BARNES, a;

citizen of the United States, resident -of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Im-` {provement in Tooth-Brushes of `which 4the following is a specification, the principle of explained and,

the invention being therein the best Amodein which I .have contemplated applying `that principle, so as -to distinguish it from other lnventlons.

My invention has reference both` to a tooth-'brush vand the method of its use.

The object is the lprovision of an `implement of thisspecificfcharaer which, when given a novel manipulation, will promote to va consummate degree, the precepts of mouth hygiene. A

My inventive conception, in so `far as I` am aware, ditffers :tnomf'alll previous ldisclosures, not only in structural detail, but also in the theoreticalprinciple of its use. Consonantly, it establishes novel means for more certainly insuring the dislodgment of all` matter, notably l:deleterious articles of food,

from between 'the teeth. scontra-distinguished therefore from the brushing process quitegenera'lly .in vogue l`at resent, my con ception deals rather wit vthe pushing bristles from through and withdrawal of the the intervenings aces of the particular set of teeth to be ceaned.` This `may be accomplished in the exemplification which the drawings suggest by rocking or tiltingthe bristle tips of the brush upon the outer contour of the teeth.

The said 'invention consists of lmeans which are 'hereinafter fully described Vand particularly set forth in the claims.

'Irhe annexed drawing and the following. description set :forth in detail certain means` i embodying i'my invention, the vdisclosed means, however, .constitutin but one of various mechanical forms in w ich `the .principle ofthe invention maybe applied.

:In said annexed drawing x-Figure 1 is an elevation of a tooth-brush embodying my invention. Fig. 2 is a section on line II-II of Fi 1. Fig. 3, is a section on line III-,

III o Fig. 2. Fig.4, is a view showing the application of mybrush to ay ltypodont of the upper jaw preparator` to cleansing `of the teeth and lookingup. ig. 5, is a. corresponding view with brush and teeth in dif-` ferent relative ppsitions vfollowing `the first manipulation.

ig. 6,.is a similar view dis= closing the position occupied by the brush The construction consists of a handle A` and back member proper a1 which as joined with angular relation to each other may yet be and preferably lare of one piece of. material. The back member is of concave-convex 'shape and iin fact, such that its concave contour substantially corresponds with the outer contour of a normal typodont designated in the drawings as B. The ytypodont B shown is that of an adult comprising the sequence from front to rear of two incisors, one canine, two bicuspids and three molars. Embedded in according to the'most approved manner, `and projecting from the concave surface of the back member, `are a plurality of non-contiguous pyramida'l bristle clusters a2, best seen in Fig.` 3. These maybe as shown in laterally extending parallel rows, a3, a, als and a, aT and a of two alined clusters each.l The rows Aare each separately designated in F ig. 2.

When the elongated cluster formation a2, best seen by cross section in Fig. 2 is adopted, each such individual cluster should have its cross-section dimension, in the direction 4of the longitudinal dimension of the back member, uniformly constructed or quite small, in `order to facilitate the compressed any particular cluster between the teeth in the manner desired.4 and presently velucidated. As best seen in Fig. 2, the cross sec- -tion of the pyramidal bristle a2 is substanf tially rectangular with one lar er dimension for the reason stated. readily understood single elongated clusters might be as satisfactorily arranged parallel with each other or a plurality of comparatively broader and 'stiffer individual bristles might be laterally alined in substantially parallel rows, each fsuch elongated cluster `or individual bristle row,4as the case mi ht be to be adapted to Islip into the spaces etween the teeth.

The rowsvas, a, a, a, a", and as are differently spaced from 'one another in the direction of ithe longitudinal dimension ofl said back member depending upon the parexample, rows'a,s and a* which are nearest the free extremity aof the back member, are

separated a distance sutlicient to span thes will `be molar-b, and in like manner, ythe rows a4 'and at might be spaced-an equal, distance so asto span the'molar b1. The rows a and a6 aswell as a and a7 are in like exem liication separated I' an equal distance f `width of the canine band the incisors b5 and b". As should be readily apparent, the express purpose in thus spacing the several pyramdal clusters a2 with definite irregularity longitudinally of the back member alis to make morelikely, just as the pyramidal shape does in and of itself, theready 'entrance of certain bristles laterally of each individual tooth. The relative spacing of successive longitudinally adjacent clusters,

while always in a measure arbitrarily determined, should be suchl that the greatest number ofteeth whichcan be simultaneously# cleansed :with convenience, will be treated with nearly uniformI thoroughness.

A ser-ies ofshorter bristles a9 extending a lesser distance from the concave surface of the back member `are also provided. These shorter bristles Vmay be arranged' in clusters ofi any specific formyand rare ar-v ranged alternately relative tothe llongitudinal alinement of the pyramidalbristles The spacing, of" the short bristles a9 is .merely such that theywil' e 'gage and hence cleanse the fiat 4surfaces 'of the teeth.4 y inclosed bythe gyramidal bristle clusters.

While they may e arra'n d'in the parallel 4rows represented, this or er is ynot essential,

provided only that they will initially engage embodied and yet adhere to t espirit of their function.

' The manipulation ofv my tooth bruslaisi1l a's (follows: Assuming the tips of the a'pproximately pyramidal clusters a? to` be 1n light `enga ementwith the -row of teeth,l as disclose in Figgl, a tilting or: rocking;

movement is imparted to the handle Where;

upon the bristles may be first forced through the spaces between the forward teeth: asseen 1n Fig. 5.

This movement contrives to loosen if not at lonce dislodge whatever foreign mat-ter `chances tovhave become' seated between these teeth.y Thereafter the tilting is set up in the opposite direction and continuedv alternatel back and fort-i1 until allnthepyramidal clu'sters a2 have beter, 1911.`

come wedged in the res ctive toothinterveningA spacesalloted v Fig. `6. In this way, the teeth are actually cleansed where deca is most apt to occur, and the desired hygienic results necessarily attained.` Practice has `furthermore.demonstrated ythat thegums very soon become calloused, .consequently .-concern `in respect to their welfare 1s unwarranted.

em, as appears 1n Having fully described my invention,'

what I claim and desire tosecure by Letters Patent. is l 1. A tooth-brush comprising the combination with an elongated back member; of

non-contiguous laterally elongated! b'ristley clusters dill'erently spaced along the longitudinal dimension of said back member, the cross section of said clusters being uniformly'constricted inthe direction of the perpendicular to said longitudinaldimenI sion.

2. A tooth-brush comprising the combination with a back member; of differing-bristle clusters respectively alined in a lateral direction; said alinements being`- spaced apart with definite `irre larityand alter'- nately arranged in the ongitudinal direction of said back member. f 1 i 3. A tooth-brush comprising the combination with a concavo-convex back member havingv a concave `contour corresponding` withl the outer contour zof the normal typo-- dont; of bristle clustersprojecting' from the concave vsurface thereof, said clusters being arranged in Substantially/parallel laterally extending rows, alternate rows being spaced withdefinite irregularity, said alterlfnatefrows of clusters being further of substantially rectangular cross section and hav- 1 ing a longitudinal dimension corresponding any particular tooth somewhat nearer; {its} y middle than its lateral edges. .In theieaseh of they wider separation of the pyraunidal`v clusters a2 required to inclose the fnuolars, 'a double row of the bristles a9 ma readily be -the later contour of a normal typodont, "bris sectional: area arranged in laterally extend` clusters oflaterally elongated cross inglggrews and projecting iven distances 'fromgthe concave surface o said me mber; other intermediary clusters ro]ect1ng a lesser-' dlstance from` said `sur ace and ar- 1 ranged. in similarly''extendingy rows', said laterally'elongated lclusters being non-contiguous and .irregularly spaced longitudinally. l Signed yby y HENRY BARNES. -At'tested by- MARGARET Momuson,
