APPARATUS FOR APPLYING CAN CLOSURES.

Application filed June 14, 1920.

To all whom it may concern:

Be it known=that I, JOHN "M. Hornnr- SAL-L, a citizen of theUnited States, residing in Brooklyn, in the 'countylof Kings and-State of-New Yorlurhave invented anew and useful Improvement in Apparatus for i-lpplying Can Closures, of which the following is aspecification.

'This invention relates in general to devices for applying can closures and has more particular reference to the provision of meansforapplying closuresto the nozzles of cans, where the nozzles have been previously positioned aipon the can bodies, al though it will be manifestasthe invention is better understood that it hasotherand more general application.

The invention is of especial value in the closing ofnozzles on large cans of the character hereinbe-fore employed for containing varnish and the like avherein a frangible disc of metal or other material is seated over :the nozzle opening and seamed in suit-able fashion with the upper'open nozzle end. Prior to my present invention it has been usually thecustom iii-sealing such nozzles with this form of closure to performthe. operation with a hand crimper orother tool which operation is a tedious one where the output is large, and results in the formation of nozzles of varying tightness andJquality of sealing. Moreover, it frequently deforms the nozzleand renders ithe can unsightly.

The principal object of my present invention is-the provision of means quickly and easily operable to apply closures to the nozzles of relatively largecans of this: and other character.

Another important object of the invention is the provision of means for producing nozzles of uniform satisfactory quality and pleasing appearance. A. further object of the invention isthe provisionof an apparatus of the character described consisting of few and simple parts requiring little or no adjustment and unlikely to require frequent repair orreplace- "merit.

Numerous other objects and advantages of the invention will be apparent as themvention is :better understood from "thefollowing description which taken in '(30I1I16G SerialgNo. 888,780.

tion with theaaccoinpanying drawing illustrates a preferred embodiment thereof: Referringto the drawing: Figure lis a side elevation ofan appara tus embodying my present invention; Figure 2 is a front view thereof; Figure 8 is a partial enlarged view in .plan, partly in section, showing the arrange ment of the passive die;

Figure 4 is a section taken vertically through the same;

Figure 5 and 6 are sections through the nozzle showing the operation.

The apparatus shownon'the drawing'foi. the purpose of illustrating the present preferred embodiment of 1 my inventive idea comprises a die press in general of anypreferred form or construction, detailed descrlption of whlch is not bellevecl necessary.

= .at-its top. 'Thisshoulder andflange are provided byoflsetting themat-erial oft-he nozzle near the end and at the shoulder 19 as 'inetic .seal is performed by curling the "flange Elover and down within theifla-nges 24 ofthe closure as indicated at 25 hrFignrezti. This nozzleaand closing aneans are new. and "form the subject matter of a cowpen'ding applicationserialNo. 388,77 9, filed by. me on June 1i, 192-0.

The nozzle 18 :isapositioned on the can prior 1 to the application of-the closure and is fixed inplace in any :suitableror.preferred manner, the showing on Figure 4 in this respect being merely schematic.

The cans are filled with their content and the closure loosely laid in place and are then dieclosed by the apparatus of the drawing. The closing instrumentalites coinprise a passive die arrangeable beneath the sive dies are in normal position.

shoulder 19 and an active die mounted in the die-carrier slide which descending presses inwardly the flange 21 and bends it in the manner shown in Figure 6, at a single operation, the while co-operating with the passive die so that uniformity of hermetic seal results.

The passive die in the present instance comprises two movable jaws 26, pivoted at 27, upon an auxiliary housing 28, mounted on the vpress table. This housing has an angular pocket 29 into which a vertical corner of the can body may be thrust. The die jaws have arcuate adjacent ends 31 provided with semi-circular or semi-conical pocle ets 32 adapted to embrace the nozzles when the dies have been swung to the normal position shown in Figure 3. Assuming the parts to be arranged as shown in this figure, the jaws tightly embrace the nozzle having an upstanding circular wall 33 engaging beneath the shoulder 19 to support it against the closing action. The active die is indicated by reference character 34 and has a closing recess 35 tapered on its outer side to first bend the flange 21 inwardly, the taper continuing to a curve at the top to curl it down over the flange 24. This is the action when the active die descends and constitutes the entire closing operation in the present instance. Thereafter, the active die ascends and the can ispulled from place, swinging the jaws 26 to an open position by reason of the outward movement of the nozzle. The next succeeding can is then merely pushed into place, its nozzle engaging the jaws 26 and moving them to the closed position for a subsequent opera tion. Each jaw 26 has a tail 36 movable beneath a guide plate 37 fixed by bolts 38 upon an upstanding curved wall 39 at the housing, these guide plates serving also-to restrain tilting of the die jaws in the closing opera tion.

Means are provided for preventing operation of the active die except when the pas- This means in the present instance consists of a rod 41 slidably mounted in hearings in the guide '37 at the right of Figure 3, in the housing and in the bed of the press, said bearings being indicated by

reference char aoters

42, 43 and 44. This rod when in nor-- mal position is arranged with a reduced part 45 .in registration with the path. of travel of a tail 36- of the right hand jaw.

alt is, however, adapted to be lowered when the treadle 26 is pressed to dispose an upper part 50 of larger diameter at this path of travel and across it. The location of the rod 41 is such, as may be observed by view ing Figure 3, that rod movement from normal position, can only occur when the dies are in normal position, i. e., embracing a can nozzle. The rod 41 is connected to an arm 45 on a shaft 46 having bearings at 47 in the press ring. The shaft 46 in turn has a second arm 48 connected by rod 49 with the lever or treadle 16. As has been stated this treadle must be depressed to produce descent of the active die 34 so that the enlarged part 50 of the rod 41 prevents this operation except when the jaws are in normal position, because otherwise the part 50 will rest on the top of the jaw and prevent any descent of the rod 41. For the coupling of the rod 41 with the clutch so that they may have the related operation above described, any well known and suitable mechanism may be employed. .1 have illustrated in Figs. 1 and 2 a rod 51 which connects the treadle 16 with a clutch shifting lever 52 which controls the movable element 53 of the clutch. The latter acts in a known manner to connect and disconnect the power wheel 13 with thepress-shaft 14.

I It is thought that the invention and many of its attendant advantages will be understood froin the foregoing without further description and it will be manifest that various changes may be made in the form, construction and arrangement of the parts without departing from thespirit and scope of the invention, or sacrificing all of its material advantages the form hereinbefore described being merely a preferred embodiment.
