6 Claim.

My invention relates to collapsible tubes con-v taining any form of paste designed to be applied to a surface with a brush, such as paint used in 'making stencils, or shoe polish in paste form.

It is a purpose of my invention to provide a holder by which a paste tube and a fountain brush are associated one with the other to permit paste from the tube to be discharged into. the brush, the holder providing a handle by which the brush can be manipulated in the customary manner to apply the paste so delivered to the brush to a surface. a

It is'also a purpose of my invention to provide a brush and tube holder in which the tube is supported on the brush against accidental collapsing, while permitting intentional collapsing either by compression with the fingers or by use of a winding key, to replenish the brush with paste when and'as required.

A further purpose of'my invention is the provision of a brush and tube holder embodying a valve which is normally closed to seal the tube against leakage or accidental expulsion of paste, but which can beopened manually to allow paste to pass into the brush.

A still further purpose of my invention is the provision of a holder which allows the ready detachment of the tube so that when empty a filled tube can be easily substituted.

I will describe only one form of fountain brush and paste tube holder embodying my invention, and will then point out the novel features thereof in claims. t

In the accompanying drawing:

Fig. l is a view showing in side elevation one form of fountain brush and tube holder embodying my invention, the open position of the frame of the holder being illustrated in dash lines.

Fig. 2 is a sectional view taken on the line 2-2 01 Fig. 1.

Fig. 3 is a fragmentary sectional view similar to Fig. 2 showing the valve of the holder in open position. v

Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 2.

Fig. 5 is an enlarged sectional view taken on the line 5-5 of Fig. 2.

Referring specifically to the drawing, my invention in its present embodiment comprises a head, designated generally at H, which is in the form of a single casting made of metal or any other suitable'material, and having a circular portion Ill screw-threaded exteriorly to receive thereon a collar ll. This collaris part'of a fountain brush B the bristles ll of which are secured ms, sci-miss. mm

between the collar and a sleeve ll having a base flange II which is secured at its edge to the inside of the collar. This sleeve I8 is of truncated coraical form to provide an opening 20 in its small The head H includes also an integral nozzle 2| of truncated conical form which, with the brush 13 applied, is adapted to extend into the sleeve to form a seat for the latter which is sufficiently snug to form a paste tight seal between the two. A duct 22 extends axially through the nozzle 2| and at the small end of the nozzle a seat 22 is formed for a valve 24 of ball form. This valve is provided with a stem 25 which is movable freely in the duct and operatively connected to a rod 28 by looping the confronting ends of stem and rod. asindicated at 21.

The rod 2' is loosely fitted in-a passage 21 formed in the head H to communicate with the duct 22. At the outer end of the passage a pocket 28 is formed in which a spring is is received. This spring surrounds the rod and engages a knob 20 on the outer end ofthe rod so as to yieldably urge therod outwardly and, through the stem 2!, to cause the valve 24 to normally occupy closed position on the seat 23.

At that side opposite from the nozzle 2|, the head H is formed with a projection 3| into which the duct 22 leads. Thisproiection is interiorly threaded to receive the neck of a conventional form of collapsible paste tube T, and to thereby place the interior of the tube in direct communication with the duct 22. For the dual purpose of holding the tube T against unscrewing from the collar II, and securing the tube in axial alinement with the head H so as to prevent lateral or transverse bendin of the tube yet allowing the tube to be compressed either by the fingers or by rolling it upon itself with a conventional form of key 33, I provide a frame I". This frame is characterized by having openings therein extending lengthwise of the frame, and made up of partswhich are separable to permit the ready attachment and detachment of a paste tube to and from the head H to allow an empty tube to be replaced by a filled one when and as required.

In the present instance the frame 1' comprises two parts 24 and l! of identical construction, each being made of a single length of wire bent in the form of a U with its free ends terminating in trunnlons 38 loosely fitted in recesses 21 in the flattened sides 38 of the projection 3|. In this manner the frame parts are plvotally mounted on the head to occupy the closed position shown opening I to prevent in solid lines in Hg. 1. orthe open position shown in dash lines in the same figure.

bights ll of the frame parts are flattened and bent inwardly so that they meet when. the frame is closed. At the point of meeting, the frame part 34 is formed with a pin ll extending into an opening I in the other frame part. A latch 42 of U-form is pivoted as at ll on the frame part 34 so that it can be swung from nonlatching position to the latched position shown in Figs. 2 and 5.

In this latched position the latch embraces the bights II to prevent the frame parts from separating, and secures the pin ll within the movement of the frame parts relatively in any direction so that the frame is held as a unit in axial alinement with the head If. Merely by moving the latch to released position and removing the pin from the opening the frame parts can be swung to open position.

In practice. the tube is applied to the holder by first opening the frame F and then screwing the tube neck into the head II. New by closing and latching the frame parts the tube is supported in axial alinement with the head but exposed at its sides to permit collapsing thereof either with the fingers or by rolling the tube upon itself through rotation of the key. the handle of which is exposed for gripping and turning.

To expel paste from the tube into the brush it is necessary first to open the valve 24 by pressing inwardly on the knob 30, when by collapsing the tube any amount of paste can be expelled into and through the duct 22 and finailyinto the brush. Once the knobis relieved of pressure the valve closes to prevent further expulsion of paste. It will be noted that by using a ball valve it cleans itself of paste as it returns to closed position and thus a paste-tight seal is effected.

With the brush supplied with paste as described the user can by gripping the frame F manipulate the brush in the usual manner to spread the paste onto a surface to be covered. To replenish the brush with paste when and as. required further collapsing of the tube preceded by opening of the valve is all that is necessary.

Although I have herein shown and described only one form of fountain and tube holder embodying my invention. it is to be understood that various changes and modifications may be made herein without departing from the spirit of my invention and the spirit and scope of the appended claims.

I claim:

1. In a holder of the character described: a head; a frame having two parts pivoted on the head to open and close; and a latch on the frame for securing the two parts in closed position. comprising a pin on and extending transversely characte prising: a head having a duct the! greases of one of the frame parts extending transversely into the other frame part, and a keeper pivoted on one frame part to secure said pin within the said other frame part.
