rAsrn-msnmsmo APPARATUS.

Application filed Kay 13,

The device, the subject of this invention is intended as a means for discharging paste from the flexible tubes in which it 1s so often found to be contained. The use of flexible tubes as paste containers has many disadvantages principal among whichis the disadvantage found in squeezing the tube at the wrong point. It is of course understood that these tubes should be compressed, commencing first at the end farthest away from the discharge orifice, and proceeding the full length of the tube' until all the contents have been discharged therefrom. Very often this procedure is not followed, with the result that the tube becomes so mi 5- shapen as to make it diflicult if not impossible to discharge all of the contents thereof. An object of this invention is, therefore, to provide means for compressing the tube uniformly, commencing at the proper spot and continuing until the paste is entirely discharged. And another object of the invention is to provide a device simple in construction and in operation so that it may be employed with great efliciency, even by the uninitiated.

The following is what I consider the best means of carrying this invention and the ac companying drawing should be referred to for a complete understanding of the specification which follows.

In the drawings:-

Fig. 1, shows a side elevation of a device.

Fig. 2, a front elevation thereof.

Fig. 3, a reverse plan view.

Fig. 4, a rear elevation.

Fig. 5, an elevation of a part removed, and

Fig. 6, a plan view of a clip.

Similar reference numerals indicate like parts in all the figures where they appear.

At 1 in Figs. 1 and 2 I show a tube which is an ordinary flexible tube wherein a paste or other preparations may be contained. At

2 I show a removable cap which closes the discharge orifice of the tube. This cap is usually screw-threaded upon the discharge orifice and may be removed at will.

The end of the tube 1 is received in a slot 3 in a tapered and rotatable member 4. ,This

rotatable member is supported in suitable perforations in the sides 5 and 6 of a cabinet or box shaped member to be later described, and the member 4 is rotated by means of a 1926. Serial No. 108,784.

knurled enlargement or, knob 7 which may 7 be formed integral with the member 4.

The members 5 and 6 are the side members of a box shaped cabinet which cabinet has a back as shown at 8, and a short dependmg front portion 9. The top of the cabinet is closed as shown at 10,'but as shown in Fig. 3 the bottom is entirely open.

-. no In the sides 5 and 6 I produce key-ways -or slots, one of which is shown at 11 in Fig.

1, and slidable in the slots is a bar 12 which is provided with grooves 13 and 14 for the reception of the sides of the slots 11. A spring 15 arranged between the bar 12 and the back portion 8 of the cabinet urges the bar 12-forward toward the member 4. The bar 12 need not be free to rotate.

In the operation of my device the sealed or crimped end of a flexible dispensing tube is inserted into the slot 3 of the member 4. The knob 7 is then turned rotating the member 4 causing the flexible tube 1 to be rolled upon the member 4. The bar 12 urged forward by the spring 15 will compress the walls of the flexible tube and if the cap 2 is removed and the knob 7 continuously rotated, all of the paste or plastic material contained in the tube will be discharged therefrom. It is understood, therefore, that only a suflicient rotation of the member 4 is anticipated which will discharge the amount of material required.

When the tube is emptied. the member 4 may be withdrawn in the direction of the arrow 16, and the emptied tube removed by sliding the member 4 out of the rolled tube. The bar may then be returned and a new tube inserted.

At 17 I Show a clip which is adapted to engage the cap 2 and as the clip is secured to the casing or cabinet by means of a flexible member 18, the cap will not become lost or' misplaced, but will always be found associatedwith the device with which it operates.

Having carefully and fully described my invention, what I claim and desire to secure 1s x I A device of thecharacter described comprising a cabinet the bottom of which is open and one side of which is partially open, the topand back of said cabinet being closed, a tapered rotatable member passing through the sidewalls of said cabinet, and having a spring between said slidable member and the slot extending inward from o e end thereof, back wall of said cabinet to urge said slidable the side walls of said cabinet being )rovided member toward said rotatable member. 10 with key slots, and a slidable mem er mov Signed at the city, county and State of 5 able in said slots and removable therefrom, New York, this 5th day of May 1926. said slidable member having grooves for engaging the walls of said slots and a coiled MILTON URY.
