(Cl. 15-I35) 4 Claims.

My invention relates to fountain brushes and collapsible tube holders of the character embodied in my co-pending application Serial No. 145,973, filed June2, 1937.

Referring specifically tothe drawing, my invention in its present embodiment comprises a fountain brush including a head I5, preferably formed of hard` rubber, and provided with an annular groove 16 in which bristles Ilv are perbrush, cap and feed The head I5 duced diameter to provide a plug 23 onk which a ing for a collapsible tube holding frame, as will be described hereinafter.

My invention also'includes a collapsible tube T adapted to contain shoe livered between the bristles of the brush. Not only is the tube nozzle N of special form, but also the socket 22, so that one coacts with the other in providing a paste sealing coupling between brush and collapsible tube which prevents accidental displacement of the tube from the brush, and yet permits manual disconnection of the two when it is desired to replace an empty tube with a filled tube.

The socket has a rounded portion 22a above which is an annular bead 22h, while the nozzle N is formed with a rounded head 25 adapted to fit within the socket and a neck 26 in which the bead 22h is adapted to be received` The nozzle N being formed of metal and the base 2| of elastic rubber, it will be clear that to insert the nozzle into the base such manual force is required to cause the head to 'pass through theV bead 22D when the latter contracts to grip the neck above the head thereby securely holding the nozzle within the socket, and sealing the two against leakage of paste around the nozzle.

The nozzle is formed on a base 21 .and the latter is made integral with the conical rigid head 28 of the Collapsible tube T. This base 21 is of special form, and likewise the cap.24 so that the base can be inserted into the cap for a distance to permit the nozzle N to be properly seated within the socket 22. Such a construction of base and cap is provided for the purpose of preventing =collapsible tubes having conventional forms of nozzle from being inserted into the socket and thus placed in communication with the feed tube I9. In other words the special form of base and ycap limits the use of the fountain brush to my particular form of collapsible tube.

The tube base is formed with `peripheral projections 29, while the upper side of the cap 24 is provided with an opening 30, the wall of which is formed with recesses 3|. The circumferential spacing of the projects 29 and the recesses 3| are the same so that when the base 2| is positioned cir-cumferentially to cause the projections to register with the recesses, the base can be inserted into the head a distance sufficient to allow the nozzle to be properly seated within the socket. Manifestly, any collapsible tube having a conventional form of nozzle and head is prevented from being inserted the projections formed between the intervening recesses of the cap.

My invention also embodies a novel form of frame for holding the collapsible tube in axial alignment with the brush, of mounting the frame parts on the cap and latching the frame 'parts in tube-holding position. The frame comprises two parts F, F, constructed of sheet metal and `provided with longitudinal slots 32, in the opposite sides of which are reinforcing beads 33. Each frame part is formed at one end with a pair of trunnions 34 adapted to engage within a pair of sockets 35 formed in the cap 24 so as to hingedly support the frame part on the cap.

The pair of sockets are formed by first cutting the cap along the vertical lines 35a and then in striking the metal adjacent the cuts so that the trunnions can be extended into the sockets with their free ends disposed to the inner side of the cap, as best illustrated in Fig. 9. As so applied the trunnions are rotatable in the sockets to allow the necessary swinging movement of the frame part, and yet they cannot be displaced from the sockets.

into the cap by reason of and a novel means v ,1 keeper 4| In order to apply the trunnions to the sockets it is first necessary to bend the free end of one of the trunnions to a right angle position, as illustrated in Fig. 9. This per 'ts the other trunnion to be extended into the respective Socket with its free end to the inside of the cap. After this the bent trunnion is straightened, by the use of a suitable tool, so that its free end is likewise disposed to the inner side of the cap.

Each frame part, at the trunnion end thereof, has an arcuate portion 36 which passes around the tube head 28 and indents the tube at a point above the head, that is when the frame part is in closed.or tube-holding position. Manifestly,

Vwith both frame parts in closed position as illustrated in Fig. 2, the arcuate portions 36 indent the tube as described for a major portion of its circumference, and in so doing serve to secure the tube against axial displacement from the brush. However, it is to be understood that when employing the head and socket connection described herein the arcuate portions are not necessary to secure the tube nozzle within the brush socket. Nevertheless, the arcuate portions are desirable las providing an additional securing means, and also they may be employed where a brush head and threaded tube nozzle, such as shown in my co-pending application hereinbefore referred to are used.

My invention also includes a simple and novel form of latch for securing the frame parts in closed or tube-holding position.V This latch comprises a pair of tubular ears 31 formed on one of the frame parts and in which a pair of pintles 38 are rotatably mounted. These pintles form the ends of a strip of metal bent at its medial portion in the form of a U to provide a yoke 39 having a curved underside, as best shown in Fig. 5. Extending from and formed integral with the yoke is a curved arm 40, by which the yoke can be rotated to engage or disengage a keeper 4|, in the form of a tubular ear, formed on the corresponding end of the other frame part.

In the closed position of the frame parts the is extended between the ears 31 so as to be axially aligned therewith. By now swinging the arm downwardly from the position shown in Fig. 3 to that shown in Fig. 4, the yoke 39 is moved to engage the keeper 4| at the base thereof and thus hold the keeper between the ears. The manner in which the yoke engages the keeper is best illustrated in Fig. 5, and it will be manifest that through the coaction of these two elements any tendency for the frame parts to separate is resisted so that the frame parts are securely latched in closed position.

In practice, paste may be expelled from the collapsible tube through compression of the tube by winding a key K thereon, the expelled paste discharging from the nozzle N into the feed tube I9 and finally between the bristles of the brush. The head and socket coupling between the nozzle and brush base 2| prevents any possible leakage of paste at this point so that all paste expressed from the tube is discharged into the feed tube. Once the collapsible tube has been emptied of all paste and a new tube is desired to be inserted, it will be clear that by unlatching the frame parts they may be swung to open position to allowthe empty tube to be pulled from the brush and a. new tube inserted.

Although I have herein shown and described only one form of fountain brush, collapsible tube and tube holder, each 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 combination, a fountain brush having an elastic socket, and a cap provided with an opening through which entrance to the socket may be had, the wall of said opening being formed with circumferentially spaced recesses; a collapsible tube having a base, a nozzle on the base adapted to fit and be retained in said socket by the elasticity thereof, said base having circumferentially spaced projections which when extended into the said recesses permits the nozzle to be inserted into the socket.

2. In combination, a fountain brush having a head, a feed tube extending through the head, a base on the head of elastic material, a socket in the base, a cap on the head housing the base and having an opening therein through which entrance to the socket may be had; a tube having a nozzle for extension into said socket, and a base from which the nozzle extends; and coacting means on the cap and tube base permitting extension of the said base into the cap only when the two are in predetermined circumferential positions and for a distance suflicient to allow the nozzle to be seated in the socket and gripped by the material of which it is formed.

3. In combination, a cap for fountain brushes having portions cut and instruck to provide sockets arranged in pairs with the sockets of each pair opening at their confronting sides to the inner side of the cap; and a two-part tube holding frame, each part having a pair of trunnions extended into the respective pair of sockets and `into the inner side of the cap.

4. In combination; a tube holding frame for fountain brushes comprising two parts mounted for pivotal movement to occupy open and closed positions; and means for securing said parts in closed position, comprising a keeper on one of said parts, and a latch pivoted on the other part to rotate ,about an axis paralleling the plane of said part, said latch having a yoke and an arm extending therefrom for moving said yoke around said keeper to a position in which it engages the latter adjacent its point of connection with the respective part and at the outer side thereof, whereby said keeper and said yoke coact to secure said parts in closed position.
