DISPENSING DEVICE.

' applicationfiled August 10, 1927. Serial No. 212,104.

The present invention concerns a dispens ing device or fixture which, in connection with materials contained in collapsible tubes, fur- One of the objects of the invention is to provide a holder for a collapsible tube filled with material which is to-be dispensed therefrom; as for example tooth paste, although it is tobe understood that other substances, as shoe polish, metal polish, shaving cream,

cold cream and the like, may be equally well dispensed by means of the improved device which is the subject of the present invention.

A further object of the invention is to pro vide a novel and efficient device for progressively compressing a collapsible tube so as to ejectgradually and evenly therefrom paste or plastic contents therein contained and to do so in such a manner that substantially all of the contents of the tube may be utilized without waste.

A still further object of the inventionis to provide a holder for the afdresaid collapsible tube and for the'compression. device co-oper ating therewith and which device is provided with a loosely pivoted coverwhich will prevent access of dust to the collapsible tube and its contents, but which cover is adapted to fall away from the mouth of the collapsible tube when-the holder supporting said tube and compressing device is swung '18 0 in a vertical direction about a pivot by means of which it is attached to a plate, which, in turn, may be attached to a suit-ablesurface, as .a wall. .1

A still further object of my invention is to provide sliding means for progressively advancing the compressing device which cooperates with the aforesaid collapsible tube so that the mouth of the said tube shall-be maintained substantially in the same'position in space throughout the discharge of the material from the collapsible tube, it being understood, of course, that the tube andholder may be turned about an angle of 180? Vertically while the material is actually dispensed; and

what is meant by maintaining the mouth of the tube substantially in the same position is, to be understood as having reference to the mouth of the tube when it is directed upwardly.

lgn the drawings which accompany and form a part of the present application:

. Referring to Figs. 1, 2, 3, 4 and 5, in which similar numbers refer to similar parts throughout, it will be seen that there is provided an escutcheon plate 1 capable of being attached to a wall or other surface 2 by means of screws or nails 3, and which plate is provided with a pivotal union 4, which, in turn, is attached to a square or oblong rod 5 terminating at both ends in a sphere or other ornamental shaped member 6. In the modifications, as shown in Figs. lto 3, the said rod 5 is also provided with a number of incisions 7 which co-operate with a spring tooth 8 located on the rear surface of a sliding sleeve 9capable of vertical movement upwardly and downwardlyupon the said rod 5 but which is normally kept in any given position by virtue of the engagement of the spring tooth 8 with the aforesaid incisions 7 Upon the sliding sleeve member 9 there is mounted a loosely hinged cover 10, being pivoted upon an extension of the sleeve at 11. The said sleeve also carries an extension which is enlarged toward one extremity thereof so as to form a hollow ring'12, as is shown in greater detail in Fig. 5. and which ring is provided at the side nearest its attach ment to the sleeve 9 with a sharp point or proectlon 13 and at the far side with a sharp point 14 mounted upon the end of a screw 15 whichco-operates with threads 16 within the said rlng, a knurled knob 17 being provided to advance or retract the aforesaid screw 15.

' The ring shown in Fig. 5 is employed to hold any spring tooth and to which sleeve 19 there is attached a collapsible tube-compressing member designated as a whole by the numeral 20. As already explained, I have provided for two different types of tube-compressing members which will be designated herein as 20 and 20 the particular type 20 being that illustrated in Fi s. 6, 7, 8 and 9, and which will be describe in greater detail hereinbelow. Referring to the tube-compressing member of the construction as shown in enlarged cross-section in Fig. 4, it will be seen that this consists of a bracket 21, of a roller 22 and a curved leaf spring 23 which bears a ainst the outside of the aforesaid roller 22. T ere is also aslotted rotatory member 23 having a slot 24 adapted to receive aflattened end 25 of a collapsible tube, as for example a tube of tooth paste, and which meniber 23, by virtue of the thereto attached'handle 26, may be rotated in a direction, which in the cross-sectional View shown in Fig. 4

would be clock-wise, so as to draw the flattened end of the tube 18 down between the said member 23 and the roller 22. To assure a sufficient compressing force upon the end of the tube 18 so as to remove substantially all of the plastic mass therein contained, the

springs .23 are made strong enough so as to hold the roller 22 forcibly against the flattened end of the tube 18. .It will be noticed that as the end 25 of the tube 18 is gradually wound about the said member 23 the entire assembly 20 will gradually'slideupwardly along the rod until substantially all of the contents of the tube 18 shall have been discharged. The position assumed by the member 20 and the sleeve 19 intermediate between a full tube and an empty tube is shown in dotted lines in Fig. 1.

When dispensing, for example tooth paste, from the dispensing device which forms the subject of the present invention, the entire device, that is to say the rod 5 and the appurtenances attached thereto, is rotated as a unit about the union a 180 so that the cover 10 may fall down by gravity thereby exposing the mouth of the collapsible tube 18, whereupon by a slight turn of the handle 26 on the compressing device 20 pressure will be applied to the contents of the tube 18 thus' forcing some of the contents 18 of the same out so that it may be applied either to the hands or to a suitable brush, such as a tooth brush, shown in dotted outlines in Fig. 3 and bearing the reference mark as a unit 18*. After a sufficient amount of the contents18 of the tube 18 has been discharged, the handle 26 is released, whereupon, by gravity, the entire assembly will rotate about the union 1 and will automatically reassume the position, shown in Fig. 1, so that the cover 10 will again fall over the mouth of the tube 18 and thus protect the contents thereof from the dust of the atmosphere.

Fig. 6 shows a modification in which the union 4 is directly attached to sleeve 9 in stead of rod 5 which latter is rigidly attached to the dispensing device 20, so that in this modification the rod ,5 will slide upwardly through the sleeve 9, instead of the sleeve 19,

moving upwardly upon' the immovable rod, I

as shown in Fig. 1. As will be seen in Fig. 6,

which shows, in dotted, lines, the tube and contents as they would appear when the tube 18 is one-half empty, in this case the rod 5 will be continually advanced upwardly through the sleeve 9. In this modification it is not necessary to have any incisions such as 7 or spring tooth such as 8 as the rod 5 will be kept from dropping by reason of the con nection between the neck of the tube and the retaining device such as shown in Fig. 5 and the co-operation of the flattened end of the tube 18 with the compressing device 20. Otherwise, the operation of the modification, as shown in Fig. 6, is identical with that already described. Referring to Figs. 7, 8 and 9, which show a simplified modification of the compressing device, this is illustrated in the aforesaid three figures in such a form as it would beused in connection with Figs. 1, 2 and 3; namely attached to a sleeve adapted to slide upon a square rod, such as rod 5; although it is to be distinctly understood that the modification 20 may also be rigidly attached to the rod according to the modification as shown in Fig. 6, as both are Within the scope of the present invention.

The compressing device 20*, shown in Figs. 7, 8 and 9, consists of a sleeve 19 (or is attached to the rod 5 as the case may be) and Y comprises a cylindrical rotatory slotted memmember -27, and which guides 28engage the pinions upon which the member 23 turns, the guides being of such length that the slotted member 27 may assume a position slightly above the cylindrical member 23, but may be placed in contact with the said member 23 in such a way that the slot in 27 and the slot 24 in the member 23 may coincide. When the aforesaid two slots coincide it becomes possible to insert through the two slots the flattened end 25 of the collapsible tube 18 and then, upon turning the handle 26, the said end will commence to wrap itself around the 0y I, lindrlcal member 23, thereby drawing the end of the tube 18 down between the two sides of the slotted member 27 thereby ejecting paste from the tube by reason of the gradual reducing diameter of the tube as it passes through the aforesaid slots. The final distancebetween the member 27 and the member 23 s so proportioned that substantially'the entIre" tube may be wound about the member 23 without jamming the device. It will be seen that in the present case of device 20*, it Wlll be possible to advance this along the collapsible tube 18 substantially to the mouth of the said tube, so that most of the contents of the tube may be utilized.

While the device as illustrated and described herein is preferably and advantage ously constructed of metal, it is to be distinctly understood that plastic or molded ,compositions having sufficient rigidity and p tensile strength may be used. For example, the rod 5 may consist of vulcanized fiber, a molded phenol resin, a casein solid, ivory, bone, or the like; and the cover 10 may likewise consist of a plastic material such as pyroxylin plastic; and the handles 26 and '17 may likewise be made of such molded material, so that the device may be made in" various colors and various shapes to harmonize the same with the general interior decorative scheme of the room or place in which it is to be employed. While the device has been shown in connection with tooth paste, it is to be understood that it may likewise be employed for dispensing shoe polish, massage cream, shaving cream, or similar toilet requisites.

It is believed that a perusal of the aforesaid Figs. 1 to 9 in connection with the herein described method of operation, will make the functioning of the dispensing device sufficiently clear to enable anyone skilled in the art to construct and'operate the same. Obvious modifications within the'skill of the mechanic, such as substitutions of knobs for handles, of a round rod for a square or oblong rod, or other means of attachment than the union 4, or other means for forcing the roller 22 (Fig. 4) into contact with theend 25 of the collapsible tube 18, and other shapes and forms of cover, will come within the scope a sleeve sliding upon a rod, and a collapsibletube compressing member mounted upon a connected to an escutcheon plate adapted to be mounted upon a vertical surface.

member slidable upon said rod, a ring-shaped holder for a collapsible tube likewise connected to said member, a second member mounted upon the same rod and connected to a device for progressively compressing a collapsible tube. V

3. A dispensing device of the class described comprising the combination of receiving means having provisions for engaging the neck of a collapsible-tube, a rod slidably associated with said receiving means for permitting movement of said receiving means along said rod,.. and a collapsible-tube comressing member slidably mounted on. said rod and movable toward said receiving means foli; progressively compressing a collapsibletue. r 4. A dispensing device of the class de scribed comprising a pivotally'mounted supporting. member,a sleeve slidable upon said supporting member, a holder for a collapsibletube connected to said sleeve, and a second sleeve like member slidable upon said rod,

and a device connected to said second sleeve for progressively compressing a collapsibletube.

5 A dispensing device" of the class described, comprising the combination of a holder for grasping the neck of a collapsible tube, a sleeve to which said holder is connected, a freely swinging cover for said collapsible tube likewise connected to 'said 5 sleeve, a rod slidably engaged by said sleeve and having connected thereto near the end opposite said sleeve a device for compressing a collapsible tube so as to discharge the contents of the same, and a mounting plate to which said rod is connected.

In Witness whereof, I have hereunto subscribed my name.
