. Patented Deed), 1913.

' United States, residing. at New York city,

county and State of New York, have jointly invented a new and Improved T ooth-Brush,

of which the following is aspecification.

This invention relates to a tooth brush of novel construction which is composed essen* tially of a plurality of short bristle bundles arranged behind one another, and encompassed by a divisible shell upon the removal of a portion of which one of the bristle bundles is likewise removed. In this way a fresh bristle bundle may be exposed after each application, so that. thebrush comes up to all modern sanitary requirements.

The invention also comprises various other features of construction, all as more fully pointed out in the specification and appended claims: 1

In tl e accompanying drawing: Figure 1 is a, si e view partly in section of a tooth 2 the tooth brush comprises a continuous breakable casing or shell, which is composed of alternating cylindrical sections 10 and tapering sections 11, the contracted front end of each tapering section opening into the annular back 12 of the adjoining cylindrical section. Within the casing constructed as described, there are fitted back of one another, a plurality of axially alined bristle bundles 13, the expanded head of each bundle being tightly grasped by one'of the tapering sections 11, while the main body'of such bundle extends a distance into the adjoining cylindrical section 10. The casing charged as described, is inclosed by a breakable tubular covering 14, which is provided with a scored circumferential line 15, near the front of each cylindrical section 10, which sect-ion may likewise be scored at this point. Between covering 14 and the several tapering sections 11, there are formed hollow spaces 16, which permit the covering to be here readily broken.

In use, the foremost bristle bundle 13 is encompassed by the foremost cylindrical section 10, so as to be protected against dust and objectionable contact. The operator now tears through the covering 14 at'the foremost hollow 16 and also through the foremost back 12 and removes the severed portions of the covering and casing, so as to expose the foremost bristle bundle 13. In this way the brush is ready for use and may be manipulated to clean the teeth. After application, the ends of the covering and'casmg are torn off on the line 15, thus likewise severing the used up bristle bundle, which is discarded. The bristle bundle next behind will now come to the front, being protected by the next cylindrical section 10, until the same is torn off prior to the next application in the manner described. This operation is repeated until the entire stick is used up.

It may be stated that in assembling the parts, the casing shaped as described, is laid out flat, the bristle bundles are fitted therein, and then the casing is rolled up into cylindriical form and connected at its overlapping en s.

With the construction shown in Figs. 35, the axially alinedbristle bundles 13' are inclosed within a wrapper 17 to form a core which in turn is inclosed by a separable shell composed of a plurality of nested cylindrical caps 18 having coniform tips 19, the caps being in turn inclosed by a breakable covering 20. The correlation of the parts here shown, is such that each bristle bundle 13 carries two of the caps 18, of which the front cap is removed prior to operation, while the second cap is removed subsequent to operation, the second severed cap carrying the soiled bristle bundle along with it. In this way, the bundles are alternately exposed and removed, so that a new and clean bundle is at all times available.

In Figs. 6 and 7, the construction is similar to that just described, the length of each cap 21 being however equal to the length of each bristle bundle. while furthermore the caps break lines with such bundles. Thus the removal of any one cap will cause the removal of one bristle bundle and the exposure of a new bundle, without however protecting said last named bundle against exposure prior to the use thereof, unless otherwise covered in suitable manner.

It may be stated that the device will form a complete and marketable brush when constructed as shown in Fig. 4, in which case however the wrapper must be of a strength suflicient to impart the necessary rigidity to the device.

We claim 1. A tooth brush comprising a plurality of bristle bundles arranged in axial alinement with each other, and of a breakable covering inclosing said bundles.

2. A tooth brush comprising a plurality of axially alined bristle bundles, a separable shell inclosing the bundles, and a covering inclosing the separable shell.

3'. A tooth brush comprising a plurality of axially alined bristle bundles, a surrounding shell composed of alternating cylindrical and tapering sections, and a breakable covering that surrounds the shell.

4. A tooth brush comprising a shell composed of a series of longitudinally alined separable sections, and a series of inclos'ed longitudinally alined bristle bundles, each of the bristle bundles bein carried by an individual shell section, w ereby the detachment of such section will efi'ect a simultaneous detachment of its bristle bundle.

5. A tooth brush comprising a continuous breakable shell composed of a series of cylindrical sections having annular backs and alternating tapering sections, the contracted front end of each tapering section opening into the annular back of the adjoining cylindrical section, a plurality of axially alined bristle bundles having expanded heads, the head of each bundle being grasped by one of the tapering sections, while the main body of such bundle extends a distance into the adjoining cylindrical section.
