AURIL M STRYKER, OF CHICAGO, IJILINOI'S, ASSIGNOR OFONE-HALF TO'GEORGE B1 HAINES,':

0F CHICAGO, ILLINOIS'.`

TOOTH-BRUSH.

To all whom it. nia/y concern:

Be it known that I, AURIoL M. STRYKER, acitizen ofthe United States, residing at Chi cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements n Tooth-Brushes, of which the following is a s eciication.

This invention re ates to brushes and more especially to tooth-brushes of the hollow handle type; and has for its object to provide a device of this character for mechanically supplying a dentifrice or other substance to the bristle-part through the handle, as will be hereinafter set forth in detail. Figure 1 is a side elevation. plan. 4 is a transverse section on a Fig. 2 is a Fig. 3 is a longitudinal section. Fig. line through the Fig. 5 is a transverse section on a line through the tubular handle. 6 is an elevation of a tube for holding the dentifrice. Fig. 7 is a longitudinal vsection thereof.

A represents a tubular handle and B the brush-part separable therefrom. The handle will ordinarily be composed of metal such as aluminum, German silver o r. the like that may be best adapted for the purpose.

The tubular handle is provided with an integral false back extension formi-ng a cap C covering the back D of the brush B, whichis detachable from the handle. The cap-extension C of the handle is provided with angular inturned flanged -edges 8 on each side of which engage grooves 9 running longitudinally in the back D of the brush, as best shown in Fig. 4. This arrangement permits of the brush and handle parts being assembled and separated by a wedging longitudinal movement.

The principal object in making the brush and handle in two separable parts is to con.

shown in Fig. 3.

longitudinally through the magazine. This spindle has a piston -14 threaded thereon so aslto-be capable of an advance forward feeding movement when the spindle is rotated in the right direction. This piston bears against the contents ofthe magazine from the rear end, as best shown in Fig. 3, which indicates that all the parts are assembled in position for use.

The outer end. of the tubular handle is closed by a removable cap 1-5, having a threaded engagement therewith. This cap is perforatedfor the passage therethrou h of the outer end 16 of the spindle 13. A ead or knob 17 is mounted on the end 16 and is secured, in place by a pin 18. A collar 19 is mounted on the s indie 13 and bears against the inner side of t e cap 15 and prevents any back thrust of the spindle in the operation of feeding the dentifrice into the brush-part.

The inner needle end 20 of the spindle exi its contents are insertedV in the tubular orhollow brush-handle for practical use, as best The tu ular handle is flattened on the y under side as at 22, and the magazine tube correspondinglyflattened as at 23, as sho'wn in F ig, 5. 'lhis feature prevents the magazine tube and the feeding piston'from turning when the spindle is rotated. The horizontal passage 21 opens downward through an aperture 24, through which the contents of the magazine reaches the bristles. l

It is obvious thata dentifrice in a powder or liquid form may be used instead of paste. When the contents of the magazine-tube is exhausted it may be recharged or another tube substituted therefor, as they will be sold separately from the brush and the manipulating spindle and parts.

In practical use a portion of the contents of the magazine tube may be forced into the brush end as needed by grasping the head 17 between the thumb and finger and turning the same, which imparts a corresponding movement to the spindle and advances the piston which presses against the body of the contents. A partial turn of the spindle will ordinarily deliver a sufficient quantity for vlo use at one time. This larranggnnent dispenses with the necessity of having to carry the dentifrice separate from the brush,l and 1 boththe dentifrice and brush are ready for simultaneous use.

Having thus described my invention, what I claim is l 1. A. tooth-brush, comprising a hollow handle andaJ brush-part having a feed-passage opening from one intothe other, a magazine tube inserted in said handle, a rotatable threaded s indle extending longitudinally therethroug and provided with a needle-end extending into saidpassage, a piston mounted on sald spindle, and means for rotating the same in lmparting a feeding movement to said piston.

2. In atooth brush, the combination with a hollow handle portion,of a separable brush portion, means for detachably securing said rush portion tothe handle portion, said4 brush portion having a channel formed therein, the rear end of which opens into the hollow handle, a pistonand a rotative member longitudinally disposed insaid hollow handle the forward end of which projects into the channel of the brush portion, said rotative member beingl adapted to impart longitudinal movement to said piston.

3. In a tooth brush, the combination with a hollow handle portion, of a separable brush portion, means for detachably securing said rush portion to the handle portion, said brush portion having a channel formed therey member being rotatively mounted in said cap and being removable with said cap.

In testimony whereof I affix my slgnature in presence of twowitness'es.
