TooTHBRUsH.
Application led March 5, 1919. Serial No. 280,780.
' To all whom it may concern.'
Be it known that We, ARTHUR vCosnivs and THOMAS RICHARD PEDEN, both subjects of the King of Great Britain, and both residents of the city of Vancouver, in the Province of lBritish Columbia, Canada, have invented certain new and useful Improvements in Toothbrushes, of which the following is a specification. v
ur invention relates to improvements in toothbrushes, and the object of our invention is to devise a simply constructed and inexpensive toothbrush the construction of which is such that the teeth may be etticiently cleaned by alternate up and down rotary movements of the brush instead of lateral movements, as is the most" common, and inelicient, practice at the present time, and which movements are accomplished easily'and with great facility by the manual operation of the brush head without the use of extraneous mechanical means. A further object is to provide a brush by means of which all the teeth may be reached and thoroughly cleaned, the back teeth as Well as the front,
hi hly eiicient.
e attain these objects by the construction illustrated by the accompanying drawthus rendering the device in s in Whichhead end surface, with the exception of the end rowv of bristles, is also convex and concave longie I Specification of Letters Patent.
view taken on theA Patented Mar. 1, 1921.
respectively' tudinally and transversely the bristle surface conthat longitudinall forms substantial y to the contour of they teeth while the transverse concave surface lends itself readily and effectively t0 the rowhich the bristles are all of the same length and arranged to present a fiat surface. j
Adjacent the brush head the handle is enlarged to form an elongated ball-shaped portion 5 adapted to be gripped by the fingers, and this portion may have a plain surface, or it may be grooved, as indicated at 6 in Figs. 1 and 2, so that a better grip for y the fingers may be provided. The remainder of the handle may be of any desired shape, but is preferably of a round section.
In use, the brush is held by gripping the portion 5 between the fingers and the bristles are applied to the teeth in the usual manner, the alternate up and/down rotary movements of the head being then obtained by rolling the portion 5 between the lingers first in one direction and then in the other.'
From the foregoing it Will be seen that We have devised a ,simple toothbrush the use of which enables the teeth to be brushed by rotary, instead of lateral, movements, thus rendering the cleaning operationl more effective.
What we claim as our invention is:
The combination with a tooth brush including a brush head and a handle, of'an ovaliform enlargment formed on the handle adjacent the head, said ovaliform enlargement being provided With a plurality of spiral grooves for a purpose specified.
Dated at Vancouver, B. C., this 24th day of Februa 1919.
