SPECIFICATION forming part of Letters Patent No. 599,816, dated March 1, 1898.

Application filed February 8, 1897. Serial No. 622,499. (No model.)

To a/ZZ whom it may concern:

Be it known that I, WILLY WALLAcH, a citizen of the United States, residing at Paris, France, have invented certain new and useful Improvementsl in Brushes, of which the following is a specification.

My invention (for which protection has been secured in France in the name of Charles Loonen, with my knowledge and consent, by a certificate of addition, dated January 25, 1897, to the original patent, No. 237,750,dated April 13, 1894) relates to improvements connected with brushes generally, but is more particularly applicable' to a ner class of brush-such as tooth-brushes, nail-brushes, and other like brushes for personal use; and the invention has special reference to improvements introduced in the kind of brush for which Letters Patent of the United States were granted to me under date of July 17, 1894, No. 523,058. v

The improvement has mainly reference to the formation of the brush-head and to the connection of that head to the handle when it is a question of manufacturing toothbrushes and other like ne brushes having al handle. ,Y

The object I have in view to accomplish is to lessen the cost of manufacture of that kind of brush, while at the same time producinga perfectly well-finished article which is very strong and the head of which, being solid, can be readily utilized for rapidly and economically attaching the bristles.

In my aforementioned patent I have described a brush-handle constituted by a hollow celluloid shell made of a single piece, into which is arranged a lling composed of a hard portion-say bone-lling out the head and capable of receiving the bristles, and of a shank or stem of any suitable metal rigidly connected to the bone or other hard material flllin g up the head by means of a metal sleeve or otherwise. This method, while perfectly well suited for proper end attachment of the bristles, calls for a labor which, if not com? plicated, at least remains more or less expensive, since it requires the following main operations: first, preparation of a celluloid 5o shell and a bone or other hard filling for the head; second, connection of such filling to the shank or metal stem of the handle; third, introduction of the filling into the shell; fourth, closing up the shell at the head end, through which the introduction takes place; fifth, sealing or cementing the stem or filling into the handle with a plastic material previous to the final closing up of the remaining otherend of the shell.

. The new method of manufacture which I 6o have. devised dispenses with a considerable amount of these operations and of the labor attendant thereupon, and, besides reducing the cost-price, it enables meto utilize with advantage in the formation of the brushhead itself the waste produced in the manufacture of certain celluloid articles.

The annexed drawing shows in section a tooth -brush made in accordance with the present improvement. 7o The brush is substantially constituted by a head ct, for the reception and fastening of the bristles b, and by a handle c. The handle c is formed of a hollow shell molded from celluloid in the manner referred to in the aforementioned patent or inl any other suitable manner, the said shell being subsequently filled up by a filling d of any suitable powdered material, compressed or not,

whether wet or dry, capable of giving con- 8o sistency and resistance to the article-such, forinst-ance, as a mixture of plaster-of-paris and water. The head a is formed of a piece of celluloid, assuming a suitable shape for the purpose required and obtained by molding or otherwise.` The lower end of the head et' surrounds the upper end of a stem f, of any suitable metal or rigid material, embedded in the celluloid during the molding operation or otherwise. Suitable projections, 9o teeth, or like asperities,such as f',are formed in any suitable manner on the embedded end of the stem ffor the purpose of increasing the adherence thereof to the celluloid.

At the lower end of the head a, surroundg5 ing the stem end f', is formed an offset a', engagingv and tting exactly theupper open end of the shell c. If desired, the connection between the head-offset a and the shell c may be perfected or increased by the use of cement roo or any other means.-

When the head has been introduced and secured into the end of the shell, as shown in Vhat I claim, and desire to seeure by Letthe drawing, the shell is lilled up through the ters Patent, is- 15 bottom hole c with any suitable filling d, as A brush comprising a brush-head, a shank described, thereby imparting consistency and or stem for said head, a hollow handle and a 5 stiness to the handle and sealing the stemf filler therein, in which said shank or stem is firmly. The bottom holeecan then be plugged anchored, for the purpose set forth. by a cemented disk of celluloid. On the stem In Witness whereof I have hereunto set my 2o f are likewise formed asperities, such as f2, hand, this 26th day of January, 1897, in presfor anchoring the stem to the filling.
