msnNsrNG DEVICE Application med December 9, 1927. Serial No. 238,883.

, This invention relates generally to dispensing devices and, more particularly, to a certain new and useful improvement 1n dispensing devices especially adapted for use 1n onnection with collapsible tubes and the ike. l

My invention has for its object the provision of a simple, durable, practical,- and convenientl operable device for eiciently, eco- ]o nomica y, and with the elimination of waste dispensing the contents of collapsible tubes and the like, such as are at the present time generally employed as containers of tooth paste, `shaving-cream, and'other semi-Huid, l5' soft, or plastic compositions or matters. I

And with the above and other objects in view, m invention resides in the novel features o form, construction, arrangement, and combination of parts hereinafter described and pointed out in the claims. In the accompanying drawing,

Figure l is an elevational view of a dispensing device embodying myinvention;

lFigure 2 is a longitudinal sectional view of the device, taken approximately on the line 2 2, Figure l;

Figure 3 is an inverted plan view of the device; Figure 4 is a side elevational view of the device; and t A Figure 5 is a slightl modified form of dispensing device embo ying my invention.

Referring now more in det-ail and by reference characters to the drawing, which illustrates practical embodiments of my invention, A designates the frame or body of the device, which is preferably constructed of suitable sheet metal bent or formed to include a back-plate or wall` 1 and laterally projecting spaced and registering or parallel side wings 2, 2, plate 1 bein preferably provided at its one or upper end reference being made to Figure 1) with apertured ears 3, 3, whereby the deviceas a whole may be conveniently suspended lupon a wall or other place of support. vUpon its upper or front face and intermediate the wings 2, plate 1 is provided with fixed and suitably spaced angular or grooved strips or rails 4, 4, form-- in a guide-way for a preferabl sheet metal tu -su porting member B pre erably in the form of) a suitably elongated plate-section 5 fitting for slidable movement in said guidewa and formed at its one or lower end with a orwardly or outwardly presented extension 6. For purposes shortly appearing, the

extension 6 is apertured and provided with a communicating sleeve 7 preferably of diametrical dimension and internally threaded to receive and engage with the neck 8' of a collapsible 'tube C.

Disposed transversely in suitably spaced relation. over the frame-plate 1 and the tubesupportin mounted or rotation upon the wings 2, is a preferably surface-rougliened or knurled roller 9 provided at an end with a toothed or gear-Wheel 10; and similarlyY disposed and supported for rotation b wings 2 and in superposed relation for tu e-engaging co-operation with the first roller 9, is a second also preferably surface-roughened or `knurled roller 11 provided at one end with a wing-nut or other suitable turning-member 12 and at its other end with a toot ed or gear wheel 13 havlng meshing engagement with the wheel 10 movable plate-section 5 and ;I`ube`C is of ordinary type standard in use today'as a container of tooth-paste, shaving cream, adhesive-paste, and other semi-fluid, soft, oreplastic commodities or matters, and in the use of my dispensing device, the usual cap of tube C is first removed, the tube C inverted, and the tube C then disposed upon the member or bracket B with its neck 8 fitting in and engaged by sleeve 7 and with its folded reduced end 14 disposed between the.'

co-operating rolls or rollers 9, 11. As the member 12 is now rotatorily manipulated, the rolls 9, 11, will, through their meshing relation, be rotated inreverse directions, whereby the tube C will be drawn upwardly and squeezed by and between the rolls and its contents consequently ejected at the mouth of the tube-neck 8. Thus, as the rolls 9, 11, are rotarily actuated, the tube-contents is correspondingly ejected in a most cleanly manner and in measured quantity, and further, as the rolls 9, 11, are co-operatively related to pinch and flatten the tube C therebetween, practically the entire contents of the tube is eventually ejected for consumption, whereb waste is eliminated. As the contents ov one tube C is so consumed, the member 12 may be reversely manipulated, when, in due course, the empty tube C may be readily removed and conveniently replaced by a second filled tube C.

Preferably, as here shown, the frame A may also include outwardly presented suitably slotted supports 15 for tooth-brushes D or the like; and preferably also forming part of the device is ai'eadily removable closure in the form preferably of a trip-lever E for the tube-neck 8, the lever E beine' pivoted intermediate its ends for swingable-movement over the under face of the extension 6 and limited Vin such movement by suitably spaced stops 16, 16. At one end, the lever E is enlarged, as at 17, to fit flatwise as a closure over the otherwise open neck 8 of tube C, and p at its other end, the 4lever E is preferably elongated, as at 18, for convenient manipulating engagement by a finger-or brush-end,

nas will be evident and as may be desired in the use of the device. d

In the form of the device as illustrated in Figures 1 to 4, both inclusive, shiftable movement of the tube-supporting member B is effected merely through and by the engagement between the rolls 9, 11, and the tube C. To more positively effect simultaneous shifting movement of the tube-supporting member B and rotary movement of the rolls 9, 11, the device, as illustrated in Figure 5, may include a suitable rack 19 longitudinally disposed on the elongated plate-section of member B, meshing with which is a pinion 20 fixed on a shaft 21 also mounted for rotation upon the wings 2 and having inter-driving connection with the rolls 9, 11, as by means of a gearwheel 22 fixed on an end thereof and having meshing engagement with the gear-wheel lO. Otherwise the modified form of the device illustrated in Figure 5 is the same as the preferred form thereof illustrated in Figures 1 to 4, and hence the parts are designated by the same'reference characters. It will be evident that, in such modified formv of the device, tube-squeezing or other rotary action of the rolls 9, 11, may be eected on direct shifting actuation imparted to the tube-supporting member B.

I am aware that various-changes in the form, construction, arrangement, and combination of the several parts of my new dispensing device may be made and substituted for those herein shown and described without departing from the nature and principle of my invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A device for dispensing by ejection the contents of a collapsible tube including, in

combination, a frame, a" tube-supporting ,member shiftable upon and relatively to the frame, a co-operating pair of rolls mounted for rotation uponfthe frame for engaging and squeezing the supported tube therebetween, and means for simultaneously efiectin positive shiftable movement of said mem er on and with rotary tube-squeezing movement of said rolls, said means. comprising a rack on said member, and a pinion having gear-connection with the rolls. Y

2. A device for dispensing the contents of a collapsible tube including, in combination, a support, spaced standards. on the support, a member slidably shiftable on the support intermediate the standards, a tube-supporting extension projecting angularly from the support and apertured for registration with the neck 'of the supported tube, a co-operating pair `of rolls mounted for rotation on the standards for engaging and squeezing the tube therebetween for effecting ejection of the tube-contents, the rolls being disposed transof the tubes contents, permanently meshed gears on the rolls for effecting rotation thereof, and a pinion having driven connection with said gears and meshing engagement with the rack for effecting shiftable movement of the plate and the supported tube on rota-` tory actuation of the rolls.

In testimony whereof, I have signed my name to this specification.

PAUL WERNER.
