5 Claims. (Cl. 221 -60) The invention relates to a paste dispensing device and more particularly to means for dispensing the contents of a collapsible tube.

The chief objects of the present invention are 5 the provision of a dispensing device having a pair of rollers horizontally disposed in side by side relation therein and ,in which a collapsible 'tube may be easily and readily placed with .the

closed end of the tube betweenthe rollers and 10 having remote control means for causing the vertical movements of said rollers to collapse the tube to emit the substance therefrom when desired.

A further object is the provision of a device of this character wherein the tube is inserted and held in an inverted position having a cap member for closing the opening thereof which is operatively connected to a driving means for causing the rollers to be moved to collapse the tube as the cap member is moved.

A still further object is the provision of a device of this character having means whereby the remote control means may be rendered inoperative and having manual control means for actuating the vertical movement of the rollers to properly position them with respect to the tube.

With the foregoing and other objects in view, which will appear as the description proceeds,

the invention resides'in the combination and ar-,

rangements of parts and in the details of construction hereinafter described and claimed, it be ing understood that changes in the precise em-- bodiment herein disclosed can be made without ing the cap member in changed position in dotted v against a stop by means of the spring 34 having lines.

Fig. 6 is an enlarged sectional view taken on the line 6-6 of Fig. 3.

Referring to the drawing, the numeral I designates a casing which is elongated in cross sec tion, having a closed top wall II and a bottom wall i2 provided with an opening I3. The top wall I l and the bottom wall l2 are each provided with an opening it and I5, respectively, into which a vertically extending screw-shaft i6 is pivotally mounted adjacent the side wall of the casing with its reduced ends H and i8 respectively extending outwardly of the walls ii and I2.

A yoke l9 provided with a threaded opening 28 is held in horizontal threaded engagement with the screw-shaft I6 and .is provided with horizontal openings adjacent each side of the 10 screw-shaft into which the shafts 2! of a pair of rollers 22 are journaled. The rollers 22 are preferably of resilient material, such as rubber, etc., and are supported in the yoke 18 in spaced side-by-side relation to receive the closed end of a collapsible tube A betweenthem. The ends 23 of the roller shafts 2| are milled to form a flat portion to receive the small spur gears 24 provided with a D-shaped center for securing them'to the rollers and in meshing engagement with the screw-shaft IS.

The free end 25 of the yoke i9 is guided in the casing I0 to permit a vertical longitudinal movement of the yoke as the screw-shaft i6 is rotated, and the rollers 22 will be caused to turn toward 25 each other by means of the gears 24 which are also in meshing engagement with the shaft I6 and on each side thereof.

A knurled knob 26 is fixed to the end i! of the screw-shaft it to manually adjust and position the rollers with respect to the tube A as it is inserted through the opening l3 in the bottom wall i2.

A cover 21 is pivoted for swinging movement on the extension I8 of the shaft i5 and is provided 5 with an arcuate slot 28 centrally thereof for receiving the neck portion of a collapsible tube A to retain the same within the casing I 0 with the closed end thereof between the rollers 22. At its free end the cover 21 is provided with a slot open- 4 ing 29 adapted to engage a headed stop 30 on the bottom wall i2 to securely retain the cover in ,position and which is also provided with a downwardly extending portion 3! forming a finger piece for manually swinging the cover member to insert or withdraw the collapsible tube. A cap member 32 is also pivotally mounted on the extension !8 of the shaft l6 and is normally urged one leg thereof anchored to the cover 21 and its other leg attached to the cap member 32.

As thus far described, it will be noted that the cover 21 and the cap member 32 are normally held together under the influence of the spring 34 and when said cover 21 is swung outwardly (see Fig. 4) the cap member 32 will move therewith and when it is brought back to its closed position. the stop 33v will force the cap member 3A to its normal at-rest position over the opening in the neck of the tube A. The cap member 32 is provided with a downwardly and outwardly turned portion 32a having a side flange 32b forming a pocket-like rest or support for a tooth brush as shown in dotted lines in Figs. 1 and 5.

A ratchet'wheel 35 is keyed to the extreme end l8 of the shaft 16 having a ratchet dog 36 pivoted at 3! on the cap member 32 and normally urged into engagement with the ratchet wheel by means of a spring 38. The dog 33 is provided with'an extension 360 adapted to engage a stop 39 fixed to the bottom wall I2 of the casing when the cover 21 is moved outwardly to open position. thereby causing the ratchet dog 36 to disengage the ratchet wheel 35 and to be re-engaged by means of the spring 38 when the cover is returned to closed position.

When the cover is in open position as above described and the dog. 36 is free of the ratchet wheel 35, (see dotted lines Fig. 4) the screw-shaft l6 may be manually turned by means of the knurled knob 26 for properly positioning the rollers 22 with-respect to the tube A.

Assuming the device to be loaded, that is, the tube A being positioned within the casing in with the closed end thereof between the rollers 22 and the cover 21 in closed position (see Figs. 4 and it is only necessary that the user position the brush against the rest or support formed by the walls 32a and 32b of the cap member 32 and press the same causing the cap member 32 to swing on the extension is of the shaft l3 and.

causing the dog 36 to engage and rotate the ratchet wheel 35 and the shaft I6, which in turn will cause the yoke l3 threaded thereto, to move downwardly and while doing so, the spur gears 24 in meshing engagement with the screw-shaft l6 will cause the rollers 22 to be positively driven to grip and collapse the tube A in their rolling movement, emitting the substance therein upon the brush which has been moved into the path of the tube. -When the brush is removed, the cap member 32 will again resume its normal at-rest position against the stop 33 under the influence of the spring 34, thereby forming an enclosure for the open end of the tube.
