WILLIAM EDWARD BANNER, OF PERTH, ONTARIO, CANADA.

TOOTH-POWDER.

No Drawing.

provements in Tooth-Powder, of which thefollowing is a specification.

This invention relates to improvements in tooth powders and the objects of the invention are to overcome the difliculties of spilling and wasting the powder which have hitherto been inherent in the use of the article' 1 While some form of tooth powder is universally recommended as the. best form of to many persons owing to the difliculty of usin the powder without scattering and wasting it. I

It has been attempted to overcome these difliculties by various forms of containers having constricted outlet apertures but the expense of constructing these is considerable, and owing to the nature of the powdered material,it has been found impossible to obtain a discharge of it in a uniform and even stream. a

I propose to overcome these diificulties by forming the powder into granules which will readily flow but which Wlll at the same time be adapted to breakdown easily when rubbed or moistened whereby they will not wear the enamel on the teeth or be otherwise unsatisfactory from a dental standpoint.

The ingredientsor material fromwhich tooth powder is formed do not form part of the present invention, which relates to the physical structure of the powder.

Any of the wellknown forms of tooth powder manufactured from chalk, borax, sodium bicarbonate, powdered soap or potassium chlorate, or other ingredients as well known in the art might be used.

The ordinary tooth powder mixture is, according to my invention, formed into small granules of about the consistency of coarse sand, the size of the granules being Specification of Letters Patent.

variedif desired to suit diflferent tastes. I have'found that a fineness of about number thirty. mesh is suitable for the purpose. The granules may be produced in any way. Preferably they are produced by moistening the powder with water or other suitable liquid and forcing the damp material through a sieve, then drying the same and then afterward putting the mixture through another sieve ofthe desired mesh, thus producing a granule which has every property of the original powder but is easier to handle and use and when in use will'be reduced again to the powder by the moistenin or rubbing. When a powder such as the is placed in a container it will be found possible to pour it therefrom on to a tooth brush without spilling and with little or no waste. The material will flow very readily and in an even stream.v I

As many chan es could be made in the above powder an many apparently widely different embodiments of the invention, within the scope of the claims, produced without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative in a limiting sense.

What I claim as my invention is:

1. As a new article of manufacture a composite commercial toothpowder comprising artificially formed granules each adapted to readily break down into powdered form when moistened or rubbed.

2. As a new article of manufacture a com posite commercial tooth powder formed-into artificial r'anules each of said granules consistin 0 down into powdere form when rubbed.

In witness whereof I have hereunto set Russnr. S. SMART, I PEARLE M. Gmow.

and not a; multiplicity of materials, said granues being ada ted readily to'be broken
