` MACHIN E FOR SECURING VESSEL-CLOSURS.

Specification of Letters Patent.

Patented Oct. 21, 1919.

Original application led April 25, 1914, Serial No. 884,362. Divided and this application led November 26, 1917. Serial No. 203,923.

To all 'whom z't may concern:

Be it known that I, EDWIN F. HULBERT, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and Sta-te of Wisconsin, have invented a new and useful Machine for Securing Vessel-Closures, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a partial section showing the flanged closure in place, Figs. 2, 3, 4 and 5 are similar views showing the successive operations performed in securing the closure in place, and Figs. 6, 7 and 8 are vertical sections through the complete dies, the positions of the dies corresponding to the positions shown in the parti-al sections lof Figs. 3, 4 and 5, respectively.

My invention relates to the securing of end closures in cans or similar packages, whether made of paper, metal, or other maferial.

This application is a division of my oopending application Serial No. 834,362, filed April 25, 1914.

rPhe object of the invention is to provide a simple and effective machine which will give a strong closure, resistant against jars or shocks in shipping, handling, etc. The invention is particularly applicable to the securing of flanged closures in paper cans,

although it may be applied to other receptacles and other materials.` The main object of my invention is to lock the closure in place without the necessity of an interior mandrel on which the receptacle body is supported.

In Fig. 1, 2 represents the side wall of the can or receptacle and 3 the closure having a circumferential outwardly projecting flange-4. In the first operation of the device an exterior circular die 5 is used having a circumferential interior recess, as shown at 6, and which die is preferably made in sections. An expansible interior die or mandrel, part of which'is shown at 7, is used in connection with the outer diev and in the first operation the parts of the inner die 7 are forced outto cause the lips on the inner die to crimp the walls of the closure flange and the can body outwardly into the groove in the outer die or anvil, all as shown in Fig. 2. In the next movement, as shown in Fig. "3', the end die 8 having a depending edge portion and a groove insidev thereof is moved downwardly within the outer die 5 and curves the registering edges of the closure flange and receptacle end inwardly and downwardly las shown. The pressure in this step, while suiicient to start the roll-over, is not suiiicien-t to overcome the support given to the cap by the pinching action of the inner and.

outer dies-5 and 7.

In the next step, shown in Fig. 4, a new outer die or anvil 9, which may be made in sections, 4and a new expanding inner die or mandrel 10 are used, but the pinching action between these dies remains the same as in the first movement, and the endwise moving die 11 acts downwardly. rollingover the registering portions of the ange and receptaclen and into the seam formed as shown.

.In the fourth and final step, shown in Fig. 5,-the inner and outer dies 12 and 13 are again changed land the order of movement is reversed. That is, the endwise moving die 14 moves downward until it rests on the recessed portion of the anvil 12 carrying with it the rolled-over seam portion until this rolled-over seam portion is brought in contact with the bottom 3 of the cap. The parts of the expand-ing inner, die 13 are thenforced outwardly and radially, as indicated by the arrow, The upper part of the recessed edge portion first cornes in contact with the upper part of the seam and the angle of contact forces the roll downwardly and outwardly into the recess or bead portion formed in the first movement. The pressure exerted by this inner die is suiiicient to tightly compress the folds together, lock the parts in place by forcing them into the bead or recess in the wall of the receptacle and give a hard wearing edge.

The advantages of my invention result mainly from doing away with the need for interior mandrel support and providing for securing closures to both ends of the receptacle, if desired. This is accomplished by the pinching action of the inner and outer dies, whichA gives suiiicient support While the preferred embodiment of the l invention has @been illustrated and Vdescribed, it is to beunderstn'od that the invention is not limited to its illustrated embodiment,"but may be embodied in other structures Within the scope of the following claims:

1. Apparatus for securing a flanged cap closure to a canwithout engaging the inside of the can, comprising a die adapted to surround the can body and having an inwardly opening groove, a die adapted to fit Within the flanged cap and having a projection to register with the groove and arranged toV force a portion of the flange and registering can bodyyinto the groove thereb forming an outwardly extending bead on t e can body, and means adapted to engage and turn over the edges of the-flangeand can body and thereby form a closure seam, the outwardly extending |bead engaging the groove Ain the first named die and serving to support can body into the groove, and a third die adapted to be moved endwise against the edges of the flange and can 'body and turn over such edges to form a seam, the can being supported by its engagement with.

this groove and projection against the end- Wise pressure of the third die; substantially as described.

3. Apparatus for securing a flanged cap closure to a can Without engaging the inside of the can, comprising a means adapted to engage and turn over by endwise pressure the edges of the flange and body to form a closure seam, and means adapted to support the lcan Lagainst such endWise pressure includin a die surrounding the can body and having an inwardly opening groove and a die fitting within the canbody and operating. to force and hold a portion of the can body and the flange Within such groove; substantially as described.

4, Apparatus for securing a flanged ca closure to a can without engaging the insi e of the can, comprising a die adapted to surround the can body, a second die adapted to fit Within the flanged cap, said dies being adapted to clamp the cap flange and body between them, and a third die adapted to be `.moved against the edges of the cap and flange body While so held and turn over the said edges to form a closure seam; substantially as described.

5. A device of the character described, comprising means for supporting a can body having a dished lid inserted in the end thereof, including an inner supporting member and an outer supporting member which are adapted to be relatively moved together to press the can body 'between' them, and a die adapted to coperate With said. supporting members to mold together the edges of the can body and lid; substantially as described.

6. A device. of the character described, comprising means for supporting `a can body having a dished lid inserted in the end
