3 Claims. Y l

The present invention relates to a device for dispensing the contents of collapsible tubes in which such products as tooth paste, shaving cream and other paste preparations are packaged, and more particularly to such a device which can be mounted on the wall of home and hotel bathrooms, or in barber shops, beauty parlors, Pullman Washrooms and thelike.

An object of this invention is to provide a novel and improved 'dispensing device of the character mentioned, affording a tube flattening and wind-up mechanism which is rigidly mounted and hence made easy to operate and positive in action. Devices heretofore relied entirely on the wind-up shaft to flatten the tube and such shaft was in many instances diii'cult to turn because of its lateral movement towards the xed discharge mouth of the tube, and such shaft was called upon to do the squeezing of the tube. In my present device, the Wind-up shaft pulls Wind-up shaft which is supported for axial rothe tube rearwise through a flattening means While it winds up the 'flattened portion of the tube. Because of such novel structure and new mode of operation, my present device is very efficient in accomplishing the purpose for which it is designed.

Another object hereof is to provide a dispensing device of the type described, affording a casing into which a filled tube is easy to mount and from which it is easily removed when the contents of such tube is exhausted.

Another object of this invention is to provide a dispensing device of the nature set forth, of novel and improved construction, in which the outer casing is not subjected to any strain occasioned by the application of force used to ilatf ten and wind-up the tube, and hence can-be thin-walled, light, and much cheaper to make.

A further object hereof is to provide a novel and improved dispensing device for the purpose mentioned, which is adaptable for all sizes of tubes.

Further objects and advantages will become apparent as this disclosure proceeds.

In the accompanying drawings forming part of this specification, similar characters of reference indicate corresponding parts' i'n-'fall the views.

Fig. 1 is a perspective view of a-dispensing' device embodying the teachings of this invention.

Fig. 2 is a rear view of Fig. 1.

Fig. 3 is a section taken' at lines 3-'3 in Fig. 1.

Fig. 4 is a section taken at lines 4-4 in Fig. 3.

Fig. 5 is a longitudinal view of the wind-up shaft.

Fig. 6 is a perspective viewpf the frame-piece included in 'the illustrated embodiment: such frame-piece presenting a slot through which the tube is drawn to flatten same prior to the rolling up of the flattened portion of the tube on the tary movement on said frame-piece. In this preferred embodiment, such frame-piece which is secured to a wall, is ofa form to serve as a sort of housing for the said wind-up shaft.

Fig. 7 is a plan view of a cut-01T blade included in the preferred lembodiment illustrated herein.

In the drawings, the numeral I5 designates generally an oblong casing which in use position is lengthwise along the vertical. Such casing is comprised of a front box member I6 and a rear box member I'l, hinged together at I8 along one side lof the casing they make. At the other side of the casing, along most of its length, the meeting edges of the box members have a lengthwise cut-out so that when the casingvis shut as in Fig. 1, the lengthwise slot I9 is formed. This slot is communicative with an enlarged opening in the side wall portion of the rear box member I1. This opening is of a size to permit the tube wind-up member 2I and the gear 22 to be inserted into and withdrawn from the casing I5, as part of the unitary structure securely carried on the shaft 23, adapted to be turned by its knob 24.

It may here be noted that upon assembly of the` device, the wind-up member 2| is within the housing offered by the frame-piece 26, while the part of the shaft 23 exposed between the gear 22 and lthe knob 24, is positioned through said slot I9 in the casing wall.

The frame-piece 26 is adapted for attachment to a wall by means of screws 21 through the holes 28 in bracket element 29. Said frame piece also serves to removably hold an end of the wind-up member 2|, for axial rotation in the reduced socket portion 30; the housing bore 25 being larger than the diameter of the wind-up member 2I, to provide space 32 for winding up the flattened portion of the `collapsible tube 3 I. In`

said frame-piece there is a slot 33 communicative with the bore 25. This slot serves as a die through which the tube v3l is drawn. Sidewise entrance into said slot 33 between the elements`l 34 forming said die, is possible.

lThe back wall of the rearV box member I'I', has

a lengthwise slot offering'the flanges 35 whichare slidably positioned in the vertical slots 36 respectively. Hence,'said frame-piece 26 also serves a's a track for movement of the casing along the vertical. A rack 31 is mounted on the inner surface of the front box member I6, and is in constant engagement with the gear 22 when the casing I5 is shut and the device is set into use condition. When the front box meml"ber I6 is opened 'as a door, it of course carries-'f the rack 31 away' from'"sfa'id'lgear"22. The bot?l tom wall of-the casing I 5, is provided withl an" interior counterbore to serve as a socket 38 for the tubes nozzle 39, and a discharge orifice 40 for the stuff forced from within theA .tube 3|. Such socket :and orifice are formed by meeting notches in the casing members I6 and I1. Also to be noted, is the face ratchet 4| on the gear 22; the teeth of which face ratchet engage the teeth 42 fixed on the frame-piece 26. `Hooks 43 serve as latch means to keep the casing .l5 shut. The numeral 44 indicates a slidably mounted cut-off blade which is linger-operated and `same. may be spring-loaded as by a spring 45.

Let us consider the device assembled as in Fig. l and Fig. 3, but minus the tube 3|. Also .let us disregard for the moment, the presence of the face gear 4|. Whendoor I6 is opened, the casing I5 would fall to vits lowest position on the frame piece26; The casing is so dimensioned that in its lowest position, the distance from the socket 38 Ato the periphery. of. the wind-up roller 32, is slightly greater than the longest length of tubel to be accommodated.

"The .usual closure cap onthe .nozzle 3.9 of the tube'3l, is discarded. The .tube is held inverted. The knob 24 is turned until the radial slot 46 is in ,register .with the die slot 33, whereupon the tubes closure edging '41 is set through lsaid die slot .and upwardly into the radial slot d6 of the wind-up .roller 2|. The casing I5 is then raised by hand. until the nozzle 3.9 ofA the tube rests in socket 38w`hereupon the door. i6 is shut. The gear 22 now engages the .rack .3l and the casing maybe locked by .the latchmeans d3. The cutoi blade 44 inrest position, .serves .to close openin?,r All.

.'Now, to eject .stuifrom :the tube 3| -out through the discharge .opening All, .the blade M .is .slid for hole thercof to .comei-nregister with said discharge opening, .andthen .knob 2li is turned a bit clock-wise to draw the tube upwardly through the flattening die slot 33, and Wind up Athe so attenedportion `or the tube, onto .the .wind-up roller` :24. .Upon return 4of the .blade to itsnormal rest' position, vthe stuff ejected is .cut off and the opening 4B closed again. Such movement of the knob 24 and incidentall-yfof .the shaft .23 and all it carries, will cause -thecasingdli :to rigey a bit due `to-action of fthegear 22 which is in engagementwith the rack 31, The pitch -of these should conform'` to wind-up roller `take-up. When the tube-contents is-spent, thecasing l5 will be in such position that its opening 20 will be concentric withtheshaft 23.

`Upon opening the door 4Hi vat this time, the wind-up shaft 23 ltogether Ywith the Wound-sup Spent tube 3| -onthe-roller 2:|, may be removed from the Lcasing .i5 by movement longitudinally of; vsaid shaft, throughthe opening 20. The wound-up tube is then removed from the roller 2:|. rlIhe open casi-ng |15- is then held raised so that the opening 2-53 is register with the housing bore 25d-n the frame-piece V2-6, whereupon the; unit ci Fig. 5 .may again be mounted and the operation of placing -a new tube 3|V repeated.

When the t-ube- 3| is comparatively large sothatits weight might-cause an unwinding from offtheV roller 2|, and' to avoid the casings falling Idue to its -own weight-when 'its door is closed, it is advisable to include the face gear teeth 4| for engagement with the'teeth 42 on the framepiece 26, .to avoidV -suchfrom happening. The springiness-of; the casi-ng material is relied on tonie-lato permit the-passing-ofsuch engageable teeth 4| and 42, when the knob 24 is turned.

When .small-sized tubes. 3i` .are-used the stiiness of the convolutions .of the completely iiattened tube portion wound on the roller 2|, would be sufficient to avoid their unwinding.

lt is advisable that the face gear whose teeth are .denoted 4by the numeral 4|, be a ratchet gear, so vthat the knob 24 can be turned only to wind up.

Although 'item 3| is commonly called a tube, its `structure is that of a container, one end of which is closed and iiattened and its opposite -end`hasa dischargeorice 39.

This invention is capable of numerous forms and various applications without departing from the essential features .herein disclosed. It iS therefore .intended `and desired that the Vembodiment shown herein -be .deemed illustrative .and not restrictive and that the patent shall cover all patentab'le novelty herein set forth; referencefbeing yhad to the following claims rather than to .the specific .description herein to indicate the scope of `this invention.
