T all whom t may cof/wem:

scription.

This invention relates to improvements in fountain brushes, particularly to that class .of fountain brushes which are used for dispensing paste, an obj ect of the invention being to provide a novel form of dispensing mechanism for the brush.

'A further object is to provide a brush o this character, which will be entirely sanii tary, and which may be readily cleaned.

invention consists in certain novel features Still another object is to provide a Jfountain brush equippedfwith a novel form of ejecting mechanism or dispensing mechanism, which will be simple and practical in construction, strong, durable and eicient in use, comparatively inexpensive to manufacture, and a brush which will be neat and at? tractive in appearance, and unlikely tov get out of order.

With these and other ob]ects 1n View, the

of construction and combinations and arrangements of parts as will be more fully hereinafter described. and pointed out in the claims.

lin the accompanying drawings:

Figure 1 is a view in longitudinal section through my improved brush, showing the same lled and ready for use;

Fi re 2 is a similarview showing thev position of the parts when the paste tube has been almost completely collapsed; and

Figure 3 is a view in section on the line 3-3 of Figure 1.

Referring in detail to the drawings, vmy improved fountain brush is provided with a hollow handle which includes an outer .shell 1 and an inner casing 2.v The inter.-

nal diameter of the shell 1 -is somewhat greater than the external diameter of the inner casing 2. .A threaded block 3 carried by 'the closed end of the'shell 1 has threaded engagement with the internally threaded out the major portion of its length is in the form of a substantially cylindrical compartment, but adjacent the end where the bristles 5 are mounted in the casing, the casing "tapers internally providing an annular tapered shoulder 6, and the tapered portion of the casing communicates with the outlet spout or passage 7. which extends into the bristles of the brush and is adapted to deliver paste directly to the brush 5.

A pair of squeezing or ejecting arms 8 are each pivotally1 mounted at one end in a recess 9 in the block 3. A spring 10 normally tends to spread the free ends of the arms 8 apart. rlhe arms 8 are flat,- as seen most clearly in Figure 3, and taper toward their free ends where they terminate in rounded portions 11 adapted to act as cam surfaces ,when the arms engage the shoulder (3.

12 represents a paste tube locatcl in the casing between the arms 8. This tube is` preferably tapered from the outlet toward the rear end of the casing and incliules a relatively long tapered snout 13. rl`he shape of the tube is merely to facilitate the clamping action of the arms 8. v

'When the brushis not in use, a dust cap 14 is adapted to be slipped over the brush and engage around the open end of the shell 1.

rThe manner of use of the brush is as follows: Assuming the cap 14 to be removed,

`it will be readily seen that turning of the sleeve relativeto the casing will eilen-t longitudlnalmovement of the arms 8 within the casing by virtue of the screwthreaded Vconnection between the casing and the block 3. kAs these arms are moved longitudinally` their rounded ends 11 will ride over the shoulder 6, the shoulder acting as a cam to force the free ends of the arms together,

paraurarica.

thus compressing the tube between the arms and expelling paste from the tube directly into the 'center of the brush 5. The casing may be disengaged from the block 3 in order to Permit refillmo' and cleaning.

In the particular embodiment of the 1nvention shown, I have illustrated a brush which is primarily intended for use as a shaving brush, but -it will be apparent that I do notV limit myself to any particular use o'f the invention, and that substantially sim -ilar constructions might be utilized in malr- .ing Ashoe blacking brushes, sto-ve blackmg brushes, mucilage brushes, painters brushes, h

stencil brushes, and various other forms of -fountain brush.

It will also be evident that various slifght changes and alterations might be made in the general form and Aarrangement of the parts described without departing `romlthe invention, and hence I do not wish to limit myself to the precise details set forth, but shall consider myself at liberty to make smh slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

l. A paste dispensing means for fountain brushes, and the like, comprising a hollow handle, a collapsible paste tube i-n the'han- (lle, said handle having a passage therein adapted to deliver paste from the tube, a pair of arms straddling the tube, means for moving the handle and arms relatively to one another, and means operated upon such movement for causing the arms to clamp the tube to expel the paste therefrom.

2. A paste dispensing means forfountain brushes, and the like, comprising a hollow handle, a collapsible paste tube in the handie, said handle having a passage therein adapted to deliver paste from the tube, a pair of arms straddling the tube, means for moving the arms longitudinally and means whereby longitudinal movement of the arms clamps the arms against the tube to expel the paste therefrom.

3. A paste dispensing means for fountain brushes, and the like, comprising a hollow handle, a collapsible tube in the handle, said handle having a passage therein adapted to deliver paste from the tube, a pair of arms s'raddling the tube, and means whereby longitudinal movement of the arms clamps the arms against the tube to expel the paste therefrom, said means comprising a tapered shoulder guiding the ends of the arms.

4. A paste dispensing means for fountain brushes and the like,- comprising a hollow handle adapted to receive a collapsible tube of paste, a pair of arms pivoted at one end and adapted to embracel a tube within the handle, means for effecting longitudinal movement of the arms relative to the handle, and means whereby such movement advances the free ends of the arms toward and adapted to embrace a tube within the handle, means for effecting longitudinal movement of the arms relative to the handle, and means whereby such movement advances the free ends of the arms toward each other, said last mentioned means comprising a tapered shoulder guiding the free ends of the arms.

6. A `paste dispensing means for fountain brushes and the like, comprising a hollow handle adapted to receive a collapsible tube of paste, a pair of arms pivoted at one end and adapted to embrace a tube within the handle, means for effecting longitudinal movement of the arms relative to the handle, means whereby such movement advances the free ends ofthe arms toward each other, and means normally tending to spread the arms apart.

7. A paste dispensing means for fountain brushes, comprising an outer shell, an inner easing, a block having threaded engagement with one end of the casing, a pair of arms in the casing pivotally connected to the block, means normally tending 'to spread the arms apart, said casing including an outlet spout adapted to deliver paste, said arms adapted to embrace and squeeze a collapsible tube in the casing to expel paste therefrom.

y8. A paste dispensing means for fountain brushes, comprising an outer shell, an inner casing, a block having threaded engagement with one end of the casing, a pair of arms in the casing pivotally connected to the block, means normally tending to spread the arms apart, said casing including an outlet spout adapted to deliver paste, said arms adapted to embrace and squeeze a collapsible tube in the casing to expel paste therefrom, and means whereby relative longitudinal movement of the shell and casing advances the arms toward one another.

9. A paste dispensing means for fountain brushes, comprising an outer shell, an inner casing, a block having threaded engagement with one end of the casing, a pair of arms in the casing p-ivotally connected to the block, means normally tending to spread the arms apa-rt, said casing including an outlet'spo'ut adapted to deliver paste, said arms adapted to embrace and squeeze a co1- lapsible tube in the casing to expel paste therefrom, and` means whereby relative longitudinal movement of the shell and casing advances the arms toward one another, said means including a tapered shoulder in the casing exerting cam action on the arms upon longitudinal movement of the same within the casing.
