FOLDING TOOTH BRUSH.

SPECIFICATION formingpart of Letters Patent No. 345,517, dated July 13. 1886.

Application filed January 8, 1885.

To all whom it may concern;

Be it known that I, RINALDO S. LAKIN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Folding Tooth-Brushes; and I do hereby declare that the same are fully described in the following specification and illustrated in the accompanying drawings.

This invention is in the nature of an improvement upon that set forth in my application for patent on Tooth-13rush and Dentifrice-Holder, filed November 20, 1882, Serial No. 77,224.

In my former invention the handle of the brush was hollow, forming a receptacle for tootl1-powder,an'd in some of the figures of the drawings the brush-head was shown as folding into a recess,where the powder was fed to the face of the bristles through an orifice leading thereto from said receptacle. This orifice was furnished with a plug or stopper to retain the powder. I employ these features with my present improvement, and add to them aslidin g protecting-plate interposed between the brushhead and the delivery-orifiee, so as to cover the latter, except when powder is to be applied to the brush, and also to exclude dust and dirt, and to prevent the dampness of the brush from clogging the orifice; and Ifurther ventilate the brush, when folded, by removing or omitting the sides of the recess into which it folded in my former plan, thus giving the air free access to the bristles to-promote their drying.

In the drawings, Figure 1 represents my im proved brush opened or spread as for use, and Fig. 2 shows it in its folded posit-ion, while Fig. 3 is a longitudinal section of the device folded, showing the sliding plate and plug drawn back to deliver powder to the brush. Fig. 4 is a detail of the back of the brush.

A is the handle, having at one end the receptacle 13, provided with the end cap, 0, to receive and retain a supply of tooth-powder.

D is the brush-head, pivoted to the handle at E, so as to fold, as shown, with the face of the bristles close to the flat central part of the handle.

Serial No.152,272. (No model.)

F is the orifice through which the powdered dentifrice is fed from the receptacle B to the face of the folded brush. This orifice runs lengthwise of the handle, just beneath the flat central part thereof, and opens through the flat surface along a central line,t-o deliver the powder to the brush. A plug, G, fills this orifice, and is movable longitudinally to open and. close the delivery. In order to prevent dampness from the brush from clogging the aperture, I provide a thin protecting-plate of metal, hard rubber, or other material, lying flat upon the central part of the handle, and interposed between itand the face of the brush. This plate has a sliding movement, so as to uncover the aperture F when it is desired to apply powder to the brush, and to cover and close said aperture at other times. This movement of the plate may be effected in any suitable way, such as swinging outwardly on a.

pivot at one of its ends or sliding laterally in grooves.
