' FOUNTAIN BRUSH AND TUBE HOLDER Filed June 2, 1937 ATTORNEY.

Patent ed Apr. 30, 1940 UNITED STATES PATEN osrlcs a I BRU:; i::; HQLI HER I Ernest L. Holienbeck, Los Angeles, Calif. Application June 2, 1937, Serial No. 145,913

. 7 Claims. My invention relates to fountain brushes and collapsible tube holders of the character embodied in my co-pending application Serial Number 66,580 filed March 2, 1936, now Patent 2,133,295.

5 It is the purpose of my present invention to provide an improved form of tube holding frame characterized by its ability to embrace a collapsibletube at a plurality of points circumferentially so as to not only prevent lateral *or transverse movement of the tube with respect to the brush,

but to permit a more careless handling of the device as a whole. without the possibility of the tube being unintentionally squeezed and paste ex- Dressed into the brush. The frame is further characterized by providing a more simple form of means for latching the frame parts in tube embracing position and to simplify the unlatching operation when desiring to insert a new tube.

It is also a purpose of my invention to provide 20 anew form of tufted 'brushwhich is characterized by the provision of tongues bendable to secure bristles in tufted form and without the necessity of employing fastening wires, cement. or any other additional bristle securing means, thus simplify- 25 ing its construction and materially lowering the cost of manufacturing. l a

A further purpose of my invention is the provision of a valve characterized by being self-closing and opening only by applying the necessary presao sure to the paste contained in the tube, thus eliminating completely the use of a manually operable valve asin myprior device. a

Still another purpose of my invention is the provision of a fountain brush and collapsible tube 35 holder wherein the brush head is so constructed as to permit direct mounting of the frame and collapsible tube on the brush and 'to thereby eliminate intermediate par-ts, all to the end of reducing the cost of manufacture of the device asa whole r 1 will describe only oneform of fountain brush and collapsible tube holder embodying my invention and willthen point out the novel features thereof in claims.

Referring specifically to the drawing, my inven tion in its present embodiment comprises a foun- 10 tain brush including a metal head made up of an outer member A of cupped'form and an inner member 3 of tabular form and received in the outer member. As best shown in Figs. 2 and 5,

the outer member comprises an annulus l 5 formed integral with a base It, the latter being provided with a central opening formed with a collar I! which is interiorly threaded as shown. At the junction of the base and annulus the'metal is instruck at two diametrically opposite points to form two pairs of sockets l8, while between each pair of sockets the annulus is formed with openings l9. On that edge of the annulus l5 opposite the base IS the former is provided with an annular series of tongues 20 whichare tapered and normally'disposed in the plane of the annulus, as shown in Fig. 5. 'I'hese tongues are adapted to be bent inwardly to assume positions at right angles to theannulus, as illustrated in Figs. 2 and 4, tosecure bristles 2| .in tufted form within the brush head. n

The inner member B comprises a metal. tube 22 formed at its innerend withan annular flange 23, which seats against the inner walls of the sockets l8 and forms a flat abutment for the inner ends of the bristles 2|.

A paste feeding element formed of elastic or similar material isincorporate'd in the brush for controlling the feed of .pasteirom the collapsible tube to a point centrally of the bristles of the' '40 brush. This element compr sesa tube 24 extending through the tube 22 and providedat its inner end with a collar25 interposed between the flange 23 and the base l6. This collar 25 isof considerable thickness and it is so shaped as to accommodate the threaded collar IT. The other end of the tube 24 extends centrally intothe bristles 2! with its outer end constructed to provide avalve V which is characterized; by being normally closed A to preventleakage of .paste: therefrom, but is .50 adapted to-be automatically opened when the paste within the tube 24 is subjected to sumcient pressure." r l r The present construction of the valve V is v best illustrated in Figs. 2, 6 and 7. wherein it will be seen that the valve is formed by so moulding the rubber that the tube is provided at 'closed to prevent discharge of paste therefrom into the brush. In the valve the urging action of the rubber is such that the slits 28 are opened by applying sufficient pressure to the paste contained within the tube, the paste engaging the inner ends 21*- of the projections to force the latter apart and thus open the slits.

Manifestly, the decreasing depth of the indentations or folds 26 also lends a tapered form to the exterior of the tube toallow a more inmounted on the closed end of the tube T for the purpose of compressing the tube through rotation thereof, to expel the paste from the tube into the brush..

For the purpose of holding the tube .T against unscrewing from the collar IT and at the same time to secure the tube fixedly in axial alignment with the feed tube 24, and yet allowing rolling of'the tube upon itself through manipulation of the key, I provide a frame which is made up of three parts 3|, 32 and 33 separable to permit the ready attachment and detachment of a paste tube to and from thebrush head to allow an empty tube to be replaced by a filled tube when and as required. The frame parts 3| and 32 are identical in constructionand each is made from a single length of wire bent'in the form of a U with its free ends terminating in pins 34 which engage within the sockets l8 in the manner illustrated in Fig. 3 to pivotally support the frame parts on the brush head. At their free or vbight ends the frame parts 3| and 82 are bent inwardly so that in closed position they contact with each other.

The third frame part 33 is likewise constructed from a single length of wire, of less gage, however, than the frame parts 3! and 32, and similarly, the ends of this frame part are bent to form pins 35 extending into the. openings 18 to pivotally mount the frame part upon the brush head.

To releasably secure the frame parts in closed position, that is, in a position in which the tube T is embraced bythe frame parts to securely hold it against any lateral bending movement with respectto the-brush head, as well as to prevent unscrewing movement of the tube from the head, keeper notches 38 are formed inthe notches the frame part 33 secures the frame parts 3| and 32 in closed position, while the notches in turn .releasably secure the frame part 83 against swinging movement. In this manner the parts of the frame are securely latched in closed position, and yet by exerting sufllcient lateral force on the frame part 33 the lugs 31 can be removed from the notches 36 to swing the frame part to one side to the other, thereby releasing the frame parts 3| and 32 to permit complete opening. of the frame when it is desired to insert or remove a paste tube.

A frame constructed as described not only'embraces the paste tube to hold it in fixed alignment with the brush head, but, by virtue of the numerous wire strands comprised in the frame situated as they are at intervals circumferentially ofthe tube and embracing the tube, there is provided the added advantage of reducing the possibility of the tube being accidentally compressed .or the user from squeezing the tube thereby inducing him to use the key 30 as intended to feed paste into the brush in the proper quantities. It will be understood that through operation of the key sufiicient pressure is built up upon the paste contained therein to expel it into the tube 24 and openthe valve so that it may pass into the center of the brush bristles. Manifestly,

once the paste is relieved of pressure by opening of the valve, the valve automatically closes to maintain the paste sealed in the feed tube against hardening.

An important feature of my invention is the construction of the brush, for irrespective of whether or not it is used as a fountain brush it will be clear. that its construction is such as to render it adaptable to any dauber type of brush. By means of the tongues 20 the bristles 2| are pinched or gripped between any two adjacent tongues to such a degree of security as to eliminate use of any other fastening means such as glue, cement, wire or the like,- to maintain the bristles permanently within thehead. In addition the bristles are secured in tufted form to minimize the accumulation and hardening of paste, paint or any other substance, andto permit ready cleaning of the brush. Also, depending upon the degree of taper of the tongues determinesthe degree of spread of the brush as a whole, for it will be clear that as the tongue taper decreases or increases the spread of each tuft is correspondingly decreased or increased.

I claim:

1. Means for holding a collapsible tube on a fountain brush head, comprising a 'three part frame; two parts of which are adaptedto be pivoted on said brush head to swing about parallel axes, and the other part pivoted on said brush head to swing about an axis at right angles to the axes of the other two parts,'said two parts outer member having an annulus, a base formed with a central opening, a collar on the-wall of the opening, twopairs of sockets in the outer member at the junction of the annulus and base;

an inner member including a tube axially within the outer member, and a flange abutting said sockew bristles extending into the outer member. around said tube and against said flange; tongues 2,198,773 on the outer member for securing the bristles within the outer member; a feed member having a tube extending through the tube of the inner open said end by applying pressure to a fluidcon-- member and betweenthe bristles, and a collar between the base and the flange.

3. A valve of the character described, compristained in the. tube to cause such pressure to act against said projections.

Means for holding a collapsible tube on a fountain brush head, comprising a three part frame two parts of which are adapted to be pivoted on the brush head to swing about parallel axes, and the other part pivoted on they brush head to swing about an axis at right angles to the axes of the other two parts, and coacting means on the frame parts for latching all of the frame parts against relative movement.-

6. A method of securing bristles in tufted form in a brush head having bendable and tapered tongues, which comprises extending the bristles lengthwise into the brush head while the tongues are disposed axially of the head, and then bending the tongues inwardly of the head so that they are extended transversely betweenthe bristles to divide the latter .into tufts and cause adjacent tongues to clamp the tufts against lengthwise displacement from the head.

7. A method of securing bristles in a head having bendable tongues, which comprises extendingthe bristles lengthwise into the brush head while the tongues are in a non-obstructing 15. brush position with respect to such inward extension 20 of the bristles, and then bending the tongues inwardly so that they are positioned transversely between the bristles.
