Specification of Letters Patent; July at,

Application; filed August 22, 191.8, Serial No, 250,928. Renewed April 21, 1922. serial No. 555,918.

To all whom it may concern:

Be it known that I, ABRAHAM B. COHEN,

a citizen. of the United States, residing .at

Far Bockaway, in the county of Queens and State of New York, have invented, certain.

new and useful Improvements in Tooth- Cleaning Devices, of which the following is This invention relates to tooth cleaning devices andniore particularly to that. class of tooth cleaning devices in which the ,cleaning surface touching the teeth and gums may be renewed at each cleaning operation.

It has more-particularly 'for its object to provide a-tooth cleanin'g implement and auxiliary means employed therewith\which will be economical .to manufacture, which will rovide a tooth cleaning materialwhich may iiethrown away after each operation,

which Will'besuperior in' its action to the ordinary bristle tooth brush.

f In the drawings,

. Figure 1 is a perspective view of the tooth cleamng roll together with the implement by which it is applied,

Figure2 is a sectional view of the tooth clean1ng-.,roll alone,

' Figure 3 is a perspective view of another form of the tooth cleaning device, and Figure at is a slightly difi'erent embodiment of an impregnated fabric for cleaning the teeth shown in Figure 3.

In Figure 1, 1 represents the tooth clean-' ing roll or device and 2 the implement by which it is applied to the teeth. 3 is the handle of the implement carrying the spring shank 4 and the tubular sleeve 5 which enables the roll 1 to be attached or detached from the implement.

Figure 2 represents a sectional view of the roll 1 which roll consists essentially of soft cotton 7 having a thin facing 10 of non absorbent cotton as shown.' This non-absorbent-cotton itself, which is inherently harder than the absorbent cotton, is made up into sheets which are rolled, into spirals and and that the compound sheet can be formed into aroll. The fibres of theone cling friction: .ally to those of theother for this purpose.

drawing, are noted as 6. A suitable dentifrice' for this purpose is made of lactose,

menthol, .carbolic acid, pulverized so'ap and. magnesium peroxide, all

is added so as to secure a semi-liquid emulsion. This emulsion is used for impregnating these cotton rolls, lhe alcohol contained in thefluid mixture evaporates'leaving the solid constituents deposited in the cotton. Since absorbent cotton has such fine pores as to prevent even the finer particles castile nely i powdered, 'to which mixture ethyl acohol from penetrating therein, even'when the absol-bent cotton has absorbed a liquid, it has not been hitherto thought possibleto drive particles of asolid; dentifrice into the pores by means of the entraining action of anj emulsion such as-above described. The said emulsion however; enlarges the pores of the cotton sufficiently so as. to enable the solid particles to be deposited therein. It will be evident. that this mixture of lactose, menthol, carbolic acid, soap and magnesium peroxide remaining distributedin the pores of the cotton is a very efficient antiseptlc and tooth cleanin'g'agent. -The rolls are used with the implement shown in Figure 1, each rollof the impregnated'fabric having the particles 6 of the dentifrice at and near its periphery. v 1 i Figure 3 shows a sheet of cotton 7 to which been applied.- This sheet has perforations 9 permitting a small portion of the cotton to be detached each time. Each portion of the fabric is then formed into a roll.

Figure 5L shows a modification of the sheet of Figure 3 in which the dentifrice 6 is applied to only one surface'of the sheet of cotton and the. sheet is not entirely impregare sold inall drug stores and many other Ha Withthe dentifrice; When a Piece f Y sheet of the absorbent cotton, put a sheet of q the non-absorbent cotton on top'of'it, and a gentle pressure is sui'ficienttp unite them,so

-" the fabric'shown in Fig. 4 is formed into a;

roll, the impregnated layer must be at the .90 the dentifrice 6 in semi-fluid form has also periphery. of the roll. Of course, if the entire fabric has beenimpregnated, the denti- --frice will be distributed in all parts thereof.

*It will be evident that other dentifrices' can be substituted for the particular compound here shown as these rolls can be treated with any dentifrice which will have a properly antiseptic and detergent effect upon the teeth.

The use of these rolls is preferable to the,

use of the tooth brush in that the cotton is soft and soothing to the. gums and its pliability enables the dentifrice to be carried to all portions of the teeth and gums and none v of the unfavorable action on the teeth and gums caused by the hard bristles of the tooth brush is present with the use of this tooth cleaning device. To clean the teeth the roll 1, held as shown in Fig. 1, is dipped into water and then rubbed over the teeth, being used in exactly the same manner as if it were 'the bristle portion of an ordinary tooth be cleaned. The non-absorbent cotton enables the sheet to hold its'shape.

I make no particular claim to the form of implement shown as it is obvious that other forms of holders can be devised for using these rolls.

What I claim is 1. A tooth cleanser comprising a composite sheet composed of an interior soft absorbent cotton and a facing composed of a fabric which does not substantially swell up when moistened, the said soft absorbent cotton having pores containing particles of solid dentifrice.

2. As an article of manufacture, a tooth cleaning device including a composite sheet having one face of soft absorbent fabric, and another face of non-absorbent fabric, the first-named fabric being impregnated with a dentifrice, which is distributed in the pores thereof. a

3. As an article of manufacture, a tooth cleaning device including a composite sheet having one face of soft absorbent cotton and another face of non-absorbent fabric, the said absorbent cotton having enlarged pores and being impregnated with a dentifrice, which is distributed in the pores thereof, the said fabric being of a character to hold said absorbent cotton in shape.

In testimony whereof I hereunto affix my signature.
