This invention relates generally to dispensing devices, and refers more particularly to an improved apparatus for dlspenslng substances which are packaged 1n collapslble 6 containers, such as tubes of tooth paste or the like.

Primarily, the invention contemplates a device of the character set forth which affords means for receiving, supporting and operating upon a collapsible tube to successively effect the dischar e of a uniform quantity of the contents of t e tube to obviate the possibility of waste by over feedlng.

As a further object, the invention comprehends in a device of the character set forth when a plied to its principal use as a dispenser fdr tooth paste, means o erable by the insertion of a tooth brush for ceding a predetermined q`uantity of tooth paste from a tooth aste tube onto the bristles of the brush where to eliminate the necessity of handling the tube, removing the closure cap and replacing said cap.

The invention further aims to provide an automatically operable valve mechanism for opening and closing the outlet of the supply.

The invention further embodies adjustable means for accommodating collapsible tubes of different lengths and for compensating for variations in the size of the threaded neck of the tube.

Further features of the invention reside in the provision of an apparatus or device of the character set forth which is comparatively simple in its construction and mode of operation, economical to produce and which is highly eicien't in its purpose.

With the above recited and other objects in view, reference is had to the following description and accompanying drawings, in which there is exhibited one example or em-A bodiment 'of the invention, while the claims define the actual scope of the same.

In the drawings:

Figure 1 is a vertical sectional view through the device with a tooth paste tube in position therein.

Figure la isa similar fragmentary View illustrating t-he'feeding of the tooth paste onto the tooth brush.

1829. Serial N0.'35B,`154.

Figure 2 is a front view of the device with the cover swung to an o en position. I

Figure 3 is an enlarge horizontal sectional view taken approximately on the line indcated at 3-3 in Figure 2.

Flgure 4-is a similar sectional view taken aplrroximately on the line indicated at 4 4 1n l Referring to the drawings by characters of reference, the device or apparatus includes a substantially box-like casing A which is preferably disposed in a vertical o'sition and which includes a top wall 10, a ottom wall 11, a rear Wall 12 and side walls 13, leaving .the front of the casing open. A front covering wall 14 is preferably connected to the casing at the lower front end by a hinge 15 and a suitable latch 16 is provided at the forward upper end for holding the cover 14 in a closed condition.

Within the casing a base 20 is supported by and attached to the bottom wall 11, and said base is provided medially of its forward portion with an upstanding member 21 formed with an opening 22 extending completely therethrough from the front to the rearV of the member. The upper end of the member 21 is provided with a circular socket 23 froml which a depending aperture 24 extends and communicates with the opening 22. An annular collar 25 is seated in the socket 23 and said collar is provided with an internal thread 26. The upper end of the collar, which is -disposed ,above the'upper end of the member 21, is provided with an annular ange 27, the periphery of which is serrated or otherwise formed to permit of manual rotation thereof. The outer periphery of the collar, which fits in the socket 23, is provided with an annular groove 28 and a screw or other equivalent retaining element 29 extends through the member 21 into the socket 23 Vand engages within the groove 28 for the purpose of removably retaining the collar in place. In

practice, the internal thread 26 of the collar' is designed to receive and engage with the threaded neck N of the collapsible tube T and it is to be understood that a number of collars 25 having threaded openings 26 respectively of varying diameters may be used to compensate for variation in the sizes of the threaded necks N of tubes of different types and sizes. In effect, the collar 25 is swiveled in the upper end of the member 21 so that in positioning the collapsible 'tube T in place, the threaded neck may be drawn into the collar b rotation of the same in one direction and tlie neck may be detached from the collar by rotation of the collar in the opposite direction.

In order to provide means for supporting the closed end E of the tube, a clamp 30 is employed which is supported from the upper end 10 of the'casing A. This-clamp includes a fixed jaw 31 and a movable jaw 32, together with means such as a screw 33, for opemng and closing the jaws and for holding the same in their relatively moved positions. The fixed jaw 31 is provided with an npwardly projecting threaded shank 34 which 1s received by an internally threaded tubular stem 35 swiveled in the upper wall 10 and provided with an externally disposed manipulating head 36, by virtue of which the clamp 30 may be vertically adjusted to coincide with variations in the length of the collapsible tube.

In order to provide means for feeding the contents of the tube T through the neck N and thence through the feed aperture 24, a pair of pressure rollers 40 and 41 is provided, which are journaled in a carrier 42 for vertical movement therewith. The carrier 42 is of substantially U-shaped construction including transversely spaced side arms 43 and 44 joined by a rearwardly disposed transversely arranged bight portion 45. The rear roller 41 is formed with trunnions 46 which are journaled in bearing openings 47 in the arms 43 and 44. The front roller 40 is provided at one end with a trunnion 48 which is journaled in a bearing opening 49 in the arm 43, while the opposite end of the roller 40 1s provided with a concentric opening 50 adapted to receive a removable trunnion 51 which is insertable through a bearing opening 52 in the arm 44. This permits of the displacement of the front roller for the purpose of facilitating the positioning or removal of the tube T within the device. In order to guide the carrier 42 vertically within the casing, the arms 43 and 44 are provided wlth vertical guide openings 53 and 54 respectively, through which vertical rods 55 and 56 extend,

said rods being rigidly secured at their upper:

and lower ends in any desired manner, preferably by the anchoring of the upper ends to the upper wall 10 of the casing and the anchoring of the lower ends to the base 20. The

feeding means further includes a feed screw shaft 57 which extends vertically of the casing A adjacent the rear wall and medially of the transverse dimension of tne casing. The feed screw shaft has its lower end arranged in a step bearing 58, which is preferably formed on the rbase 2O and has its upper end journaled in a bearing openingr 59 in the top Wall l0 of the casing. shaft extends through a slot 60 in the bight portion 45v of the carrier 42, and a block 6L is arranged for sliding movement in the slot 60, which block is provided with a concavethreaded surface 62 adapted to mate with the threads on the feed screw shaft 57. A spring 63 normally functions to advance the block in a direction to engage the concave threaded surface 62 with the threads of the feed screw shaft. The block 61 is further provided with an upwardly projecting handle 64 for retracting the block against the action of the spring 63 so that the carrier 42 may bev moved vertically without rotating the feed screw shaft 57.

The feed screw In order to provide means for successively l turning the feed screw shaft in a counterclockwise direction, as indicated by the arrow in Figure 4, for the purpose of moving the carrier 42 downwardly so that the pressure rollers 40 and 41 contacting with diametrically opposite sides of the tube T will express the contents of the tube through the neck and feed aperture 24, a ratchet wheel 70 is employed. The ratchet wheel 7 0 is keyed to the feed screw shaft 57 at its lower end and a ratchet pawl 71 is designed to cooperate with the teeth of the ratchet wheel. The ratchet pawl is fulcrumed as at 72 to a lever 73 and a spring 74 functions to press the ratchet pawl 71 into engagement with the toothed periphery of the ratchet wheel. The lever 73 is fulcrumed as at 75 and is provided with a spring 76 which functions to normally swing the lever forwardly from the dotted line position in Figure 4 to the full line position. The free end 77 of the lever is of a size and configuration approximating the transverse area of the opening 22 and is formed with a forward concave face 78, the purpose of which will be hereafter brought out.

In order to provide means for normally closing the feed aperture or outlet 24, a slide valve plate 8O is mounted on the upper wall of the opening 22 for fore and aft sliding movement between said upper wall and the beads or ribs 81. In order to automatically veffect movement of the slide valve plate 80.

opposite points of the upper closed end of the tube. The device is now ready for use, and the Vuser by inserting the bristle end B of the tooth brush C into the casing through the doorway 85, swings the door 86 downwardly. rlhe forward end D of the tooth brush head exerts a thrust on the concave face 7 S of the end 77 of the lever. The initial swinging of the lever retracts or moves the valve plate 80 to uncover the feedor dis charge aperture 24 and continued yin- 'ward movement of the brush causes the pawl 7l to turn the ratchet wheel 70 in the counterclockwise direction indicated b the arrow in Figure 4. This turns the fee screw shaft 57 thereof, which causes the carrier 42 and pressure rollers 40 and 41 to move downwardly with respect to the fixed tube T. Obviously, pressure is exerted onthe tube for feeding therefrom a predetermined quantit of the contents of the tube onto the toot brush bristles B whilethe same are being moved rearwardly. This spreads the discharged uantity of the contents over the bristles. en the brush is withdrawn, the

' spring. 76 swings the lever 73 forwardly to the normal position While the pawl 7l freely ratchets over the peripheral teeth of the ratchet wheel 70. Gbviously, the ratchet wheel and shaft 57 are not turned in the opposite direction so that the carrier 42 and pressure rollers 40 and 41 remain stationary until the next operation. `As the lever is swung forwardly, the coupling pin or connection 82 moves the valve plate 80 to cut off the contents and to again close the feed or discharge aperture 24. As the brush is withdrawnthrough the doorway 85, the spring 88 functions to again close the door 86 so that the casing is com letely closed against the entrance of dust, irt or other foreign matteil which may tend to settle upon and contaminate the surfaces of the device. When the contents have been completely dispensed from the tube, it is obvious that the same may be removed and replaced by a' fresh tube, as

previously explained.
