fApplication filed November 19, 1912. Serial No. 732,397.

To all whom it may concern -Be'it known that I, Gnonen W. BEaDLE, a citizen of the United States, residing at Bayonne, in the county of Hudson and State pertains to make and use the same.

of New Jersey, have invented certain new and useful Improvements in Machines for Capping Cartons; and I do hereby declare the following to be a full, clear, andexact description of the invention, such 'as w ll enab'le others skilledin the art to which it ap- This invention relates to a machine for applying slip closures to'paper cartons, and

and more efiicient than has been heretofore has for its obgect to provide a means which will form the closures and fit them tothe carton body in a. manner more expeditious proposed.

To theseends the invention consists in the novel details of construction and comb nations of parts more fully hereinafter disclosed and claims. Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views :-,-Figure 1 is a diagrammatic View in section of a mechanism illustrating m in- *similar to Fig. 1, but showing the parts from VentiOm-"and showing the" position 0 the parts" immediately before the carton carrying mandrel is elevated; Fig. 2 is a view [a direction at right angles" to that from which Fig. 1 is taken; Fig. 3 is a view similar to Fig. 2,"but showing the positionof '-"the'parts after the cap has been applied to the carton; Fig. 4 is a sectional viewof a carton after the'cap' has been applied with my machine; and, Fig. 5 is an enlarged dejtail yiew showing the oint made between the cap and the carton body.

1 indicates any suitable bed plate provided v with an orifice 2 into which fits the portion '3 of thepaper carrying die 4:, and 5 indicates a cap secured to the said portion 3, provided with the orifice 6, and with the guide pins 7 surrounded by the springs 8, as shown. On the upper end of the springs 8 rests the sliding sleeve 9, the upper edge of which, comes flush with the upper edge of the die 4, as shown. Passing over the die 4 is the paper 10 from which the caps are to be made and coacting with the said die 4 is the cutting plunger 11 operated by the connecting rods 12, coacting with the eccentrics 13 carparticularly pointed out in the i said sleeve.

r ied by the operated shaft 14. The said out A the sprocket wheel 18 over which passes the chain 19, and operated by said chain is the sprocket 20 connected to the ing the cam 22, coacting with the movable mandrel extension or stem 23, provided with the expandingcore 24, over which fits the expandingmembers of the mandrel 25. The

said mandrel extension 23 is carried by the swinging arms 26 pivoted on the stud 27, carrying the detent means 28 adapted to fit in notches 29 in the hub of the arm 26.

There are a plurality of arms 26, three being shown in the drawings, and each carry mandrels' and mandrel stems 23, not shown. Further, these said arms 26' and mandrels may be rotated by hand, or by any other means, so as to bring each mandrel 25 successively in register with the orifice 6 of the die plate 4:, and when said mandrels are thus in register, the detent 28 holds them firmly in place.

' 30 represents carton bodies which are slipped over each of the mandrels employed.

The operation of my machine is as fol- '1ows:'Power being applied to the shaft 14:,

the cutting plunger 11 descends and cuts out a disk from the paper 10, which disk is forced into the die 4:, and rests upon the upper edge of the spring controlled sleeve l).

-The continued rotation of the shaft 14 next brings the forming plunger 15 into contact with the disk, and as the outer diameter of the said forming plunger is less than the inner diameter of the sleeve 9, it passes into The parts are so timed that shaft 21 carry-.

when the forming plunger reaches the disk,

the mandrel 25. carrying the carton 30, also reaches the disk. The interior diameter of the forming plunger 15 is the same as the exterior diameter of the carton 30, and the mandrel 25 is provided with a slight depression 35 at its extreme upper end, so as to accommodate, when in its expanded condition, the thickness of the disk or closure 36, as will be clear from Fig. 3. The parts are further so proportioned that the lifting of the mandrel 25 into contact with the disk is not sufiicient to expand the said mandrel,

and consequently, as the forming plunger 15 continues to descend and the mandrel to ascend, the said closure 36 will pass inside the beveled lower end 37 of the forming plunger 15, and the material of the said closure will consequently be formed into the shape of a cap. To facilitate this formation, which necessitates a greater or less flow of the paper material, the said material may be either previously moistened, as with steam, or it may be treated with parafiin. If the cap, however, is made of a very high grade of paper, and if its dimensions are not too great, the particles of the paper will adjust themselves, without further treatment, to the form of the cap. In ordinary cases, however, I prefer to either moisten the paper, or to paraflin the same. As the forming plunger 15 continues to descend, and the mandrel 25 continues to ascend, the core 24 of the mandrel expands the said mandrel, and consequently forces the turned over lip 37 of the cap 36 into the extreme end portion 38 of the carton body, and forms a joint'like that shown in Fig. 5. That is to say, the turned over lip 37 is tapered, or more or less wedge-shaped, as indicated, while the extreme end 38 of the carton 30 is likewise more or less tapered, as shown. It results from this, that an exceedingly tight cap closure is provided, which cannot be removed accidentally, and which maintains its tight joint under all conditions of use. Further,

; the outer diameter of the flange 37 and the body portion of the carton 30, being the same, a flush surface is provided, which renders it possible for these cartons to be la.- beled in an ordinary labeling machine without any difiiculty at all. In other words, the labels, such as 40- indicated in Fig. 4, can be applied flush with the ends of the package, in the regular labeling machines,f and no complications are experienced at all, which is not the case when the ca is of a larger diameter than the carton bo y. Itcis therefore an important feature of my invention that the interior diameter of the hollow forming plunger 15 is of the same size as the exterior of the finished carton. It is further an important feature of my invention that the material of the cap is caused to flow, as indicated, because it makes an exceedinglytight joint between a paper bodyportion and a flanged paper cap portion, which is a very diflicult problem to solve.

It is obvious that those skilled in the art may vary the details of construction as well eter equal to the exterior diameter of the carton body to be closed; an expansible mandrel carrying said carton body; means for causing a relative movement between said mandrel and forming plunger; and 7 means for expanding said mandrel, substantially as described.
