DISPENSER.

Application filed December 12, 1927. Seria1 No. 239,386.

This invention relates particularly to brushes of the fountain type wherein the material to be dispensed by said brush is supplied thereto from a source of supply in constant communication with the brush.

An object of the invention is to provide a vfountain brush in conlmunieation with a container containing the material to be dispensed therefrom, said container' being held in a casing to form a handle for the brush, and having a means within said casingto act upon the container and to discharge the contents thereof as desired, onto the brush.

A further object of the invention is to provide a fountain brush communicating with a container containing a medium to be dispensed, in conjunction with a casing' housing the said container', and having means arranged therein to be advanced lengthwise thereof into contact with the said container to dispense the contents of said container' onto the brush.

Other vobjects and advantages of the invention are toprovide a fountain brush that will be superior in point of simplicity, in-

expe11si\'eness of constructimr, positiveness of operation, and facility and convenience in use and general efficiency.

In this specification and the annexed drawiI1gs,-tl1e invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following;` the description, it is desired to cover the invention in whatsoever form it may be elnbodied. l

In the accompanying one sheet of drawings:

Fig.' 1 represents a longitudinal section through a fountain brush constructed in accordance with my invention.

Fig. 2 is a section similar to Fig. l showing the apparatus for ejecting the material to be dispensed onto the brush, in the extended position.

F1 gr. 3 is an enlarged section taken through Fig. l, on the line 3 3, showing' the nested relationship of the dispensingv members.

Fig. 4 is an enlarged cross section taken through Fig. 2 on the line 4 4, showing the roller for ejecting'. the material to be dispensed onto the brush.

In detail the constructiml illustrated in the drawings comprises a hollow casing 1, that may be either of circular or polygonal cross section, and which at one end is threaded to receive a cap 2 therefor. The cap 2 is provided with a central opening; 3 therethrough. A tube 4 of material to be dispensed, such as tooth paste, shaving cream. paints, or any other material, is mounted within the casing 1 so that the threaded discharge end 5 of said tube projects through and beyond the opening;r 3 in the cap 2. The tube t .is a conventional type of container formed of iexible and collapsible material that. may be easily compressed and which,

under compression, will flatten out so that the entire contents of said tube may be ejected therefrom. n

A brush (l has the stenrend thereofdrilled and threaded to engage the threaded outle; 5 on the tube. ly threading the stem end of the brush onto the end of the tube, both the said bruslralul tube are advanced relative to each other and into relatively tight -entfagenient with opposite faces of the cap 2. The brush stem 7 is provided with a central port 8 theretllrolurh, that extends outwardly through the stem of said brush to a point where it communicates with the bristles of the brush. Thus, the contents of the tube pass therefrom outwardly through the channel in the stem of the. brush and into the bristles thereof, from which it may be dispensed. Although I have shown a brush substantially indicative of a tooth brush, it is to be understood that this invention is not limited thereto, as the invention clearly contempla-tes that a paint brush, or shaving; brush, or any other type of brush, can be connected to `the discharge end of the tube and that the invention will function equally as well. i

A strip of spring steel 9 is arranged di-` agonally lengthwise Within the casing 1, said strip 9 being spot welded or otherwise suitably secured at l0 to the interior of the casing 1, and mov-ably connected at 11 at its other end to a diametrically opposite side of the casing 1. The strip 9 is flexible so that it will adapt' itself to the area within the casing not occupied by the tube 4 and as shown in Fig. 1, when the tube is full, passes over and around said tube.

An annular cap 124is mounted over the opposite open end of the easing 1, and a shouldered shaft 13 is journaled within the cap 12 coaxially with the casing 1. knurled handle 14 is securely connected by a pin 15 to the end of the shaft 13 that projects beyond the casing 1 in order to elleet rotation of said shaft. A tubular member 16 is secured to the end of the shaft 13 withi. substantially the entire length thereof.

Cil

in the casing 1 and an end of -said tube 16 butts against thev inner face of the cap 12. The tube 16 is lixedly secured to the shaft 13 whereby the handle 14, shaft 13 and tube 16 form an integral unit, and will rotate in unison in the bearing formed in the cap 12. The tube 16 is provided with a spiralfiute or groove 17 cut therein', and extended substantially the entire length thereof.

A tube 18 having kan outer diameter less than the inner diameter of the tube 16, is telescopically mounted or nested therein. The tube 18 has a shaft or pin 19 extending diametrically thereacross and an end of said pin projects into the spiral groove 17 on the outer tube 16. The tube 18 is likewise provided with a spiral groove 2O extending A tube 21 having an outer diameter slightly less than the inner diameter of the tube 18 is telescoped therein, and said tube 21 has a pin 22 secured thereon that projects beyond the circumference thereofl into confinement within the spirally inclined groove 2O in the tube 1S. rlhe tube 21 is also provided willi a spirally inclined groove 23 that extends substantially from end to end thereof. A lube 24 is nested within the tube 21, said tube 24 having a pin 25 projecting therefrom into the spirally inclined groove 23 in the tube 21. An eyclet bearing 26 is secured within the free outer end of the tube 24 and a roller or ejector' 27 is rotatably mounted on the lwaring 26. rI`he roller 27 has an annular groove 28 cut centrally therearound to form a shaft 29, which will rotate in the eyelet bearing 26. The periphery of the roller is adapted to roll on the strip 9 of spring metal, and the opposite ends of the roller 27 are shaped to conform to the inner contour of the casing 1. In order to prevent the roller 27 from rotating within the casing 1 and to cause said roller to roll in the same path at all times on the trackaway 9, I have seated a pair of balls 30 and 31 on the opposite ends of the roller 27 on the rolling axis thereof, whereby said balls are adapted to roll within the opposite angulaijunctures of the casing 1. The balls 36 and 31 reduce to a minimum the rolling friction between the roller 27 and the casing 1, and in addition prevent the said A operator then rotates the handle 14 which has the effect of turning the larger tube 16 relative to the smaller tubes nested within it, and by reason of the engagement of the pin 19 with the spiral groove 17, all of the said nested tubes are advanced or extended outwardly, and the roller ejector 27 is gradually forced into contact with the container 4 to squeeze the said container against the side of the casing 1, and by reason of the pressure thereby created within the said container, the contents thereof are forced outwardly onto the brush. Continuous turning movement of the outer tube 16 causes the pin 19 to be advanced upon the spiral traekway therein, from one end thereof to the other without any extended telescopic action taking place between any of the other tubes 18, 21 and 24. As the pin 19 reaches the end of its travel in the tube 16, and the turning movement is continued, then the pin 22 on the tube 21 commences to turn in the spiral trackway 2O in the tube 18 until the tube 21 has been extended from the tube and finally, as the rotation continues, the pin 25 in the tube 24, that engages the spiral tracliway 23 in the tube 21, is caused to advance throughout the entire length thereof to extend the tube 24 beyond the end of the tube21. Asv

each of the plurality of tubes is .extended in telescopic relationship, one beyond the other, the roller ejector 27 advances the entire length of the container 4 until it reaches the position shown in Fig. 2 to cause the entire contents of the container 4 to be discharged therefrom onto the brush.

Having thus described this invention, what I claim and desire to secure by Letters Patent is:

1. A device to eject the contents of a collapsible tube comprising a casing; means to hold the filled collapsible tube therein; a plurality of telescopically nested members rotatably mounted in said casing, each member having a spiral groove therearound to engage a pin on the member nested therein whereby the members can be extended axially from the nested relation; and a roller on an end of one of the nested members to engage the tube to squeeze the tube between the roller and casing as the nested members are extended.

2. A device to eject the contents of a collapsible tube comprising a casing; means to hold the filled collapsible tube therein; a roller Within the casing; a, flexible strip interposed between the roller and tube to form a trackway for the roller; and rotary actu ated telescopic means mounted within the casing connected to the roller to advance the roller lengthwise of the casing into Contact with the tube to squeeze the lled tube between the ejector and casing.

In testimony whereof, I have hereunto set 10 my hand at San Francisco, California, this 23rd day of November, 1927.

RICHARD B. SMITH.
