Specification of Letters Patent.

Patented March 16, 1909.

appiimion ma my va1, mos.l smal Na. 434,012.

To all whomit may. concern:

Be it known that 1I, JEssE L. HrTz, a citi- Azen of the United States'of America, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Tooth-Brushes, of which the following is a specification.

This invention relates to improvements in tooth brushes and its object is to provide means whereby a quantity .of toothpaste or other semi-solid dentifrice maybe contained Within the handle of the brush, and a small uantity thereof forced into the bristles of t e brush, whenever it is desired to use the same.

Another object is to provide means whereby the ordinary commercial soft metal tube, such as is frequently used to contain tooth paste, may be secured in the handle and a quantity of the paste fed into the bristles.

Another object is to simplify and cheapen devices of this kind and to otherwise improve uponl the construction thereof.

Tosuch end this invention consists in certain novel features of construction and arrangement, a description of which will be found 4in the following specification and the essential features of whichlwill bemore definitely pointed out in the claims appended hereto.

The invention is clearly illustrated in the drawings furnished herewith, in which- Figure 1 is a side view of the preferred l form of my brush. Fig. 2 is a central, vertical,.longitudinal section thereof, showing the parts in-the position occupied when the outlet or discharge port is opened to discharge a quantity ofthe paste. Fig. 3 is an end view of the handle and *tube .contained therein. Fig. 4 is a vertical cross section taken on the line4-4 of Fig. 1 and Fi 5 is a view artly, -1n side elevation and art y in vertical, ongitudinal section of a s ightly 'modified form of construction.

Referring to these drawings, A, represents' the head of the brush, and B, the handle. The head comprises the usual back 1 1, having the bristles 12, upon its lower face and said back is provided witha central, longitudinal bore 13, which is adapted to receive the neck 14, of the handle B. Said neck is longitudinally movable the bore and forms a assageway which opens out through an outet or discharge port 15, formed at the end of the bore 13;

I desire to provide some simple means for preventing accidental longitudinal movement of the parts when the outlet port is closed-by the neck 14, and as shown this consists in a small knob 16, which may be formed by indenting the wall of the back 11, and said knob is adapted to'enter and seat itself in a de ression 17, formed-in the neck 14. It is evldent that when this knob is seated in the depression some little force must be exerted to move the back u on the neck. I have provided means for eepin the outlet port `15, clear, and as shown, this means consists in a cleaning pin 18, which is secured in the neck 14, and adapted to move back and forth across the opening 15, whenever the back 11, is moved upon the neck 14. It is evident that this opening may be closed by ushing theV back 11, toward the handle unti the end of the neck covers the opening 15, and engages with the end wall 19, of the bore 13, and that by reason of the engagement of the knob 116, with the depression 17, the neck 14, will be securely held in lace over the opening 15.

I-prefer to ma e the handle in the form of a flattened or oval shaped tube, as seen in Fig. 3, and this handle is adapted to receive a tube 20, such as is usually employed to contain the tooth paste. The neck 21, of the tube 20, is threaded, and upon said threaded neck is ordinarily screwed a cap (not shown). i This cap is first unscrewed and the tube screwed into an internally threaded portion 24, of the neck 14. Communication is thus established between the interior of the tube and theyoutlet opening 15, and it is evident that by reducing the size ofthe tube 20, the contents thereof may be forced out through the outlet opening 15. I provide a key 22, upon the end of the tube whichkey projects out through a slot 23, formed in the wall of the handle where it may be conveniently grasped by the user to wind up the tube. B winding up the tube the size thereof is decreased and the contents forced out through the neck 14, and-opening 15, and in between the bristles of the brush. When the tube is empty it may be removed by first. unwinding the same until the key is brought beyond the end of the handle, whereupon the tube may be unscrewed from the internal threads in the neck 14, and a filled tube screwed into place -to take the place of the empty one.

In operation the back 11, is pulled forward to uncover the` discharge opening 15, after which the key is given a slight turn, thus forcing a quantity of the tooth paste out' through the opening 15. The back 11, is then pushed back, closing the opening 15, after which the brush may be used in the ordinary manner. 'lhis forms an exceedingly simple and convenient device and one which is not liable to get out of order. Furthermore, Whenever it is desired to clean out the brush the tube 20, may be unscrewed and water allowed to run through the handle and bore 13. v

In the construction shown in Fig. 5, the neck 14a, is revolubly mounted in the back 11, of the brush and the end of said neck is cut oil' on an angle as shown at 141. This provides an overhanging end which will cover the opening 15,wl1en the parts are in one position or the handle may be turned half way around so that the opening will be uncovered. I prefer to employ devices for properly positioning the back of the brush with respect to the neck, and as shown, have provided a knob 16a, .upon the neck which is adapted to engage with depressions 17,

formed in the bore of the back. This contrivance is arranged to hold the back in a position whereby the outlet opening will be either covered or uncovered by the end of the neck 14a.

More or less variations of theparts are possible without departing from the spirit of my invention, and I desire therefore not to limit myself to the exact construction shown and described.

I claim as new and desire to secure by Letters Patent:
