IMPROVEMENT IN TOOTH-PASTES.

Specification forming part of Letters Patent No. 152,098 dated June 16, 1874; appli ation filed May 4, 1874.

To all whom it may concern Beitknown that LTHOMAS A. D.FORS1ER, of Philadelphia, in the county of Philadelphia and State ot'Pennsylvania, haveinvented a certain new and useful Tooth-Paste, and method of putting up the same; and I do hereby declare the following to be a full, clear, and ex, act description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which is represented a vertical central section of the metallic tube containing tooth-paste.

My invention. has for its object to provide a tooth-paste which will always retain its plastic form, and to put up the same in a manner which will render it air-tight or isolated from atmospheric influences at the same time that it may be ready and convenient for use. My invention consists, first, in combining any suitable powder with glycerine, or glycerine and water, which will reduce said powder to a plastic condition; secondly, in putting up tooth-paste in a metallic tube with a screwtop, such as is commonly employed for artists colors.

I take any suitable tootlrpowder and combine the same with glycerine and water, say as follows: Take prepared chalk and precipitated chalk, of each one pound; orris root, pulverized, four ounces; elm-bark, pulverized, two ounces; carmine, pulverized, suflicient quantity; essential oil or oils, sutticient quantity; glycerine and water, sufiicient quantity. Make into a thin paste. Sugar may be added, if desired.

The above forms an admirable tooth-paste, the glyeerine serving as a vehicle to reduce the solid matter to a paste, and prevent the same from becoming dry. In order to prevent the injurious eifect of the air upon this paste, and also to make it readily applicable to the purposes for which it is designed, I inclose it in thin metallic tubes with screw-caps,

such as are ordinarily employed for holding artists colors.

A represents a tube of this construction, and B the screw-cap thereof. In order to give a merchantable appearance to these tubes and render them more sightly and suitable for the toilet, I cover them with silver paper a, and place a jewel, b, in the cap.

I am aware that tooth-paste, so called, has been in use for many years. I therefore base my principal claim on the assumption that I am the first to producea tooth-paste ot' a semitluid consistency, and always ready for use, the tooth-pastes heretofore offered being simply soaps, which must have been dissolved be-' fore use, and which, from the nature of their composition, hardened and became unfit for application. Furthermore, I admit the em ployment, in dentifrices, of glycerine, in such small quantities, however, as to have merely a sweetening, and perhaps a healing, properly. My claim to novelty in its use is based, therefore, on its combination with a tooth-powder, to reduce the latter to paste, and to preserve its plastic form.

hat I then claim as my invention, and desire to secure by Letters Patent," is- 1. lIhe combination of chalk, orris-root, elmbark, glycerine, and water, substantially as and for the purpose set forth.

2. Atooth-paste rendered permanently semi fluid by the admixture of glycerine and water, substantially as specified.

3. As a new article of manufacture, a semifiuid tooth-paste.

4. A package of semi-fluid tooth-paste in a collapsible tube, substantially such as herein described, the same constituting a new article of manufacture.

In testimony that I claim the foregoing I have hereunto set my hand this 2d day of May, 1874.

it-messes: THOMAS A. D. FORSTER.
