HENRY H. FREUND, OF WEEHAWKEN, NEW JERSEY.

PRESS-FOR SEALING TUBE ENDS.

To all whom it may concern:

Be it known that I, HENRY I-I. FREUND, a citizen of the United States of America, residing at l Veehawken, Hudson county, State of New Jersey, have invented certain new -of collapsible tubes such, for instance, as are used to contain tooth or shaving-paste, said seals consistingof channeled strips that are slipped over the ends of'the tubes. The seals, when placed upon the tubes, will be somewhat loose, but my improved device is arranged to cause a portion of the seals to interlock with a portion of the tube. My improved device is also arranged to' place record indications upon the seals, the said indications acting as a supplemental seal, as will hereinafter be explained. I will now proceed to describe my inven tion in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein Figure 1 is a side elevation of an embodiment of my invention;

Fig. 2 is an enlarged plan view of the end of the support which carries one of the dies;

Fig. 3 is an enlarged bottom plan view of the end of the movable carrier which supports the other die Fig. 4 is an enlarged end view of the assembled carrier and support together with.

the dies carried thereby;

Fig. 5 is an enlarged perspective view of the upper die;

Fig. 6 is an enlarged perspective view of a portion of a collapsible tube and a seal applied thereto;

Fig. 7 is a similar view illustrating the appearance of the seal after having been acted upon by the dies.

Fig. 8 is an enlarged sectional view, the section being taken on a line 88 in Fig. 7 and Fig. 9 is an enlarged perspective view of. the seal.

As herein indicated, my improved end sealing device or. press consists of a support 10 having upstanding ears 1]., 11, to which Specification of Letters Patent. Patented Aug, 21, 1917;

Application filed March 24, 1917. 7 Serial NO. 157,077.

a carrier 12 is oivotally secured by a pin 13 which passes t rough the ears 11 and hub 1 of the carrier. instance embodied in the form of a lever which is acted upon by aneccentric cam 15 carried by a shaft 16 journa'led in the ears 17 carried by the support 10. To rock the carrier 12 respectively. The die 24L is fixed to the support 10 by screws 26, while the die The carrier 12 is in this 25 is removably secured to the carrier 12 by a clamp 26. The clamp 26 consists of a bar pivotally secured to the carrier 12, at one end thereof, by a screw 27, the other end of said clamp being provided with a, recess or jaw 28 to receive a locking-screw 28 carried by the support 12. The upper die 25 is setin a pocket 29* carried by the carrier 12 and the clamp26 passes over the die held in said pocket. When the locking screw 28 is screwed down tightly against said clamp,

the die 25 will be held securely in place.

A further feature of my invention consists in providing supplemental impression devices which in this instance consist of type 29carried by the die 25. To retain the type 29, I provide the die 25'with a recess or pocket 30 into which the type are placed, said type being held in said recess by the clamp 26. The clamp 26 performs two functions,that of holding the die 25 in place and also that of holding the type in place in said die.

The type 29 are arranged to represent a i certain identification, for instance, the serial number of a certain, lot of goods, or any other private identification. I also preferably provide the lower die 24: with fixed type or impression devices 31 and 32 indicating A and B respectively. The letters A and B represent preferably the name of the manufacturer.

The type 29 and also the impression devices 31 and 32 are arranged to form impressions in the seals deep enough to cause said impressions to interlock with the mateinafter explained.

To produce a perfect seal, 1 provide the die 25 with elongated projections 33 at each end thereof, and the die 24 with elongated depressions 34: at each end thereof, to aline withthe projections on the die 25.

The seals consist of channeled strips .35

of relatively thin material which are previously formed and slipped .on to the ends 36 'otflthe 'tubes 3.7. After the S6LlS',l1tL\ '6 been placed on to the tubes, theends of the tubes are placed between thedies 24; and 25, the press being of course ,in operation, a guide 37 being provided to aline the-ends of the tubes with the "dies.

"Wfhen the dies come together they will crush the seal and end of tube therebetween together, but unless some interlocking effect is produced, the tubes will be liable to leak and the seals liable to come off.

To prevent the seals from vcoining off, and also to prevent leakage, I interlock the seals and tubes. To interlock the seals and tubes is'the function of .the projections 33, on the upper die, and the depressions 34 in the lowerdie. When the dies come together, the projections 33 will force a portion of the seals and a portion ofthe tubes toward the depressions 34 in the lowerdie. The impress'ion type 29 and impression devices 31 and 32Will also force their corresponding portions of the seals inwardly to interlock with the material of the tubes, Aftera tube has been withdrawn from the press, it will appear asshown in Figs. 7 and 8'. After asea'l has been acted upon by the dies, the said seal will -be interlocked with the tube and cannot be withdrawn. The interlocking of the seals and tubes both by the projections and depressions of the diesand also by the type 29 and impression devices or type 31 and 32 effectively produce a leak-proof seal.

To regulatethe movement of the carrier 12,

'1 provide an adjustable screw 38 which acts upon ajplate39 Which in turn rests upon the cam 15. The opening between the dies 2% and 25 can be increased or decreased by regulating the screw 38.

WVhat-Et-claim as my invention is:

1. In :a device of the kind described, in combination, a support, a die carrier movably mounted thereupon, said carrierhav ing a ztront flat side formed with a rectangular socket, a rectangular die fitting snugly in said socket ,flush with the outer side of said carrier, said ,die'being formed centrally with ,a rectangular recess, .a plurality .of .interchangeable dies fitting said recess and frictionall ngaging one another, and a clamping bar engaging ythe-flat side of said carrier and adapte'd to bearagainst said rectangular die .as well as against said interchangeable dies, all Kof sald dies ,hav ng 11npression-making pro ect ons.

2. rIn -a ,device of the kind described, in

combination, a support, a'carrier movably carried thereupon, a fixed die carried by said support, ,said carrier having a socket, a ,die fitting saidgsocket and having a transverse recess, a plurality .of type fitting in said recess, ,a pair vvof depending impressionimaking projections formed at the'opposite ends of said fdie said first-nameddie having cavities at the opposite ends ofits upper side adapted to receive said .impressionsmaking projections, and unitary vmeans for simultaneously clampingsaid second-named die and said first-named type within said carrier.
