Specification of Letters Patent.

Patented July 22, 1913.

` Application filed March 23, 1911. Serial N o. 616,540.

To all whom i may concern Be it known that l, EUGENE D. Ci-iELLis, a citizen of the United Sta-tes, residing at lortlafnd, county of Cumberland, State of Maine, have Iinvented certain new and usewhich the following is a specification.

This invention relates-to crimpers and particularly to crimping tool for turning the engaging' lingers of a. closure under the shoulder of a vessel mouth.

In many lines of packaging it is eX- 'tlemely desirable that the closure be permanently attachedto the mouth of the vessel so (hat it .may not be remo-ved after filling. This is well illustrated in modern packaging of oils, varnishes and similar materials which are put up in metallic cans or in containers having a 4metallic mouth `or nozzle.

The requirements,- ditlir-,ulties and practice in this art may yperhaps be best understood by reference to particular types and for the purposes of illustration, my present invention will be dismissed in the terms of a spe citic type ot' closure and ot' container mouth.

lliil the application of my swinging metal seal shown in my previous United States 882,550, to a metal vessel having a flanged or shouldered rim it llas been found desirable to clench the shoiililer engaging fingers under thc rim after the vessel has beenv filled and sealed in order to preventrefilling or otherwise tampering with the contents. this end l have devised my present invention in which l have provided for the turning of these fingers into close contact with the flange of the can, thus locking the closure securely in place.

The construction and operation of? my device will be more fully disclosed in the speer licatin which follows and an illustrative embodiment, which l have found satisfac- 'tory in the practical working of my inven tion, is shown in` the drawings. I also show illustrations of the closure and vessel mout-h I to which it is applied.

Throughout the specification and drawings like reference numerals are employed .to indicate corresponding parts and in the can lip prior to clencliing. Fig. Sis a similar .View after clenching. Fig. 9 is a view of the cap to'be applied. Fig. 10 is a View.

of a can neck upon which the closure of Fig. 9 is to be clenched.

1 is a segmental base h aving a supporting shoulder 2 mounted in any suitable way as over a notch in a bench or table (not shown). i 3 are legs formed on said base supporting the tubular column 4 in which is mounted for vertical reciprocation a plunger 5. The plunger 5 is recessed at its lower end as at 6 and is surrounded near vits upper end by a collar 7 secured to it by `a pin 8.

0 is a sleeve within the column 4 held by a set screw 10.

11 is a spring .coiled about the plunger. 5 and abutting at'its lower end against the sleeve Q and at its upper end against the collar 7 thus normally tending to hold the plungerup to permit the plunger to' be depressed intothe position shown in Fig. 1.

Above tlietubular bore of the column 4 is formed a handle 12 and a coperating han- F ig. 7 is an enlargedV de=y tail, an end section showing a closure and (lle-13 is pivot-ed at 14between ears formed at the upper end of the column 4.

15 is a linkY pivoted to the plunger` 5 at 16' and between ears on the under side of the handle 1311s at- 17.

18 is a screw stop witli a lock nut 19 threaded into a projection 20 on the liandle 13.

.21 is a die plate segmental in form and preferably of about 270o extent, that is to say, an opening of about may be left in its front side, for the reason which will be explained herein. The die plate 21 has an overhanging peripheral rim or flange 22 adapted to rest on the shoulder 2 of the base 1. The inner edge of the plate 21 is grooved as at 23. (See Fig. 5.) This groove 23 constitutes the forming recess for clenching the lugs of the cap.

26 is a followenhaving a circular 'bearing rimy 27 provided with arib 28 and having a central stem 29 which may be pinned as at 30 in the socket 6 in the end 0f the plunger These followers 26 and dies 21 are provided in different sizes to fit different sized can nozzles and diii'ercnt sized closures.

Referring to Fig. S) the closure consists of -a cap A surrounded by a depending flange or rim B from which engaging fingers depend. These fingers C are usually 4 in number, two smaller ones being arranged close together adjacent to pivot I) by the cover li and the other two heilig arranged at substantially 900 from said point l of pivot l). These fingers C are to be engaged or clenched beneath a shoulder l" formed by rolling under the edge of a lip G vformed on a neck l-l. For this reason it is only necessary that the die be slightly greater in circumferential extent than 180C. In my prior patents herein before referred to I have usually shown these shoulder engaging fingers C as curved in order to provide for a spring engagement with a shoulder vessel mouth'. Although closures with suoli curved fingers may be applied to a vessel and subsequently clenched in my machine such prior curving is not absolutely necessary. In fact it is somewhat more convenient to leave these fingers straight so that the closure may be applied direct instead of requiring a lateral movement.

In operating my machine therefore the neck of the filled can is thrust through the open side ot the die 21. It' a can with a smaller sized mouth is to be sealed, a die having a correspondingly small opening, as indicated at 211 Fig. .(5 may be used. The closure is then applied with its point of pivot tothe rear andits uningered side toward the open side ot the die. This leaves thel locking lip li" on the open side of the die. vAt the same time that the closure is placed upon the can a sealing wafer and a pack K are included within the depending flangeli. During this operation the plunger 5 is held up by the spring 11 so that the follower 2G is clear of the die. 'hen the can and closure are in place the handle 13 is depressed until ythe stop 18 permits no further motion. This stop 1S is adjusted so that the follower will advance i l i just" far enough to securely clencli the iingers C of the closure Without unduly compressing the cover on the closure as will be seen by reference to Figs. l, 7 and 3. The follower 26 has a recess 271 within the circular rim 27. This is to receive the raised center 'El of the closure E. This center usually embossed and the recess 271 is depended upon to protect this raised center. Upon the release of the handle 13 the springl1 raises the plunger 5 and the follower 26 and the'can neck H may be raised and laterally removed with the closure permanently engaged thereon.

Various modifications may obviously be made in the construction and operation of my device all without departing from the spirit of my invention it' within the limits of the appended claims.

That l. therefore claim and desire to secure by Letters Patent is:

l. A device for crimping the fingers 'of a closure beneath the shouldered mouth of a containing vessel, comprising an open sided support, a removable open sided die in said support, said die having a groove about the inner margin thereof, a plunger mounted for vertical reciprocatiou in said support and a head on said plunger adapted to engage said closure and force said closure and mouth against said die.

2. A device for crimping the fingers of a closure beneath the shouldered mouth of a containing vessel, comprising an open sided support having a supporting shoulder, a removable open sided die having an over hanging margin vadapted to bear on the supporting shoulder of said support, said die having a groove about the inner margin thereof, a plunger mounted for vertical reriproeation in said support and a head on said plunger adapted to engage said closure and force said closure and mouth against said die.

ln testimony whereof, l aflix my signature in presence of two witnesses.
