ALFRED L. KRONQUEST, OF CHICAGO, ILLINOIS, AND JOHN C. TALIAFERRO, 0F BAMIMOEE, MARYLAND, ASSIQNORS TO CONTINENTAL CAN (30., INCORPO RATED, OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK.

OAN-CLOSING MACHINE.

Specification of Letters Patent.

Patented Aug. 3, 1920.

To all whom it me concern:

Be it known til at We, ALFRED L. Knoxv- QUEST and JOHN C. TALIAFERRO, citizens of the United. States, residing at Chicago, in the county of Cook State of Illinois, and Baltimore Maryland, have invented certain new and useful Improvements in Can-Closv more particularly to a can closing Ina-chine wherein an end or a cover is secured to the can body by a'double seaming mechanism.

An object of the invention is to provide a continuously operating can closing machine wherein the can body travels continuously in a forward direction and in a curved path and wherein means is provided for assembling can ends or covers and the can bodies, for rounding up the can body for seating the can end or cover in the can body and for double seaming the end or cover to the can bod A further object of the invention is to provide a machine of the above character with means for marking the cover as it passes from a stack holder to assembled position relative to the can body to which it is to be attached.

A still further object of the invention is to provide a machine of the above character wherein the can body and its cover are assembled by a mechanism located outside of the seaming machine, which assembling mechanism includes-devices for gradually lowering the cover on the can body as they move forwardto the seaming machine, so

that said cover registers with and rests on the can body as it enters the seaming mane. v t A still furtherobjectof the invention is to prgyjdea machine of the above character wherem theassemhling mechanism and the seaming mechanism 'coiiperate in rounding up thecan bodyipreparatory to the seating of the cover in t' e can body by the chuck of-the seaming-ma hine.

Another object of the invention is to pro vide a machine of the above character wherein the cover or end is attached to the can body by a single seamin roll having a first operation groove i'ormet therein and a sec ond operatiodgroove formed therein, said grooves being disposed one above the other and means is provided for moving the seaming roll and can body relative to each other for bringing about the operation of the first and second seaming grooves in succession.

Still another object of the invention is to provide a seaming machine wherein the seaming roll is fixedly secured to the spindle which carries the same and means is provided for positively operating the spindle, the spindle being of suflicien-t length so that the metal thereof may yield to permit the seamin roll to pass the side seams of the can bod thus doing away with all yielding pads or cushions heretofore used or such purpose.

Still another object of the invention is to provide a seaming mechanism wherein the seaming roll is provided with first and second operation grooves, which seaming roll is positively operated by a can having an adjust able section for varying the tightness of the first operation and wherein also the seaming roll may be bodily shifted relative to its supporting spindle, so that the tightness of both operations may be simultaneously varied.

Still another object of the invention is to provide a seaming machine of the above character wherein the seaming roll has first and second operation grooves and wherein said seaming roll is operated positively by a cam with means for permitting the withdrawal ofthe seaming roll from the can between the first and second operations, so

.that the can may be removed for inspection. 7

Another object of the invention is to provide a closing machine wherein the can.

travels continuously forward in a curved" path in an upright position, which machine has means for rounding up the canbody; for assembling the cover and the can body, for seating the cover in the can body while it is rounded up and for seaming the cover to the can bod with :rmechanism for timing the can bodies as theyare delivered to the as semblin mechanism, which marks and '5 places t 1e cover on the can body, which timlng mechanism presents the can body to the view of the operator for inspection.

A'further object of the invention is to provide a machne of the above character in which the timing of the cans. is brought about by rotating traveling supports for the Mean odies, which supports have different "-speeds of travel, so that the can bodies are gradually shifted by a rotation thereof until brought into contact with the timing fingers.

Still another object of the invention is to provide means associated with the timing mechanism for determining whether covers are to be fed from the stack, so that covers will only be fed as a can body passes to the can body and cover assembling mechanism.

Still another object of the invention is to provide a marker for a machine of the above character, which marks the cover while it is traveling and which marker. includes means whereby it may be readily changed so as to vary the identifying mark placed on the cover.

These and other objects will in part, be

obvious and will in part be hereinafter more fully described.
