Application filed December 18, 1916. Serial No. 137,634.

To all whom it may concern Be it known that I, PETER KRUsE, a citizen of the United States of America, residing in the borough of Brooklyn, county of. Kings, city and State of- New York, have invented c ertain new and useful Improve,

ments in Machines for Seaming Heads .or Ends on Cans, of which the following is a specification. v

TlllS lnvention relates to machines for seaming heads or ends on cans or can bodies, and aims to provide improvements therein. The general characteristics of the present invention resemble those set forth in my United States Patent No. 1,143,97 6, granted June 22, 1915. g The present invention provides a machine which is readily adapted'for seaming heads Fig. 2 being a transverse sectional vie on the line IL-II of Fig. 1.

11 designates a seaming ring and 15 an opposite seaming sector. One of these parts performs the first seaming operation and the other the second. One or both of these seamers is preferably rotatable.

The can bodies and ends are supported by suitable means, as chucks 7 and 8, these means or chucks being displaceable to move the can bodles and ends Into successive operation with the seamers. The chucks 7 and 8 are'also preferably mounted upon a rotatable carrier, as'the plates 1 and 2, the carrier acting to move the cans and ends from areceiving position to. a discharge position.

The plates 1 and 2 may be conveniently fixed upon a shaft 3 rotated by a suitable pulley 4. and a train of gears 5.. As stated, one of the seamers, as the scanner 11, is rotatable, and to this end one of the carriers, as the carrier 1, serves as a convenient support for the support 10 which carries the said seamer 11. The support 10 and seaming ring 11 are rotated upon the carrier 1 by suitable gearing l2 and rack 13, the gearing 12 being actuated from the drive shaft 14. The rotation-of the seamer 11 is ordinarily in the same direction as, and faster than that of the carriers 1, 2 on which the chucks 7, S-are carried, thecan and, assembled head being thereby given a rotation in the same direction as it subsequently rolls on the seaming sector15f about to be described. J

In my Patent 1,143,597 6 the seamer corresponding to the segment 15 herein is shown as rotatably mounted upon thecarrier corresponding to the carrier lherei'n. The seaming sector 15 might besimilarly arranged. Preferably, however, the seaming sector 15 is carried upon brackets'16projecting from.

the frame of the machine. The seaming sector 15 is preferably removably and adjustably mounted upon the brackets, and to thisend is provided'with slots 15 through which the fastening bolts pass.

Operation: The seaming of heads or ends on cans is usually effected in two operations, called the first seaming operation and the second seaming operation. As here shown,

the first seaming operation. Can bodies and ends are fed to the machine by a suitable feed means 20, the bodies and ends being received and held together by a pair of chucks 7 and 8 upon the carriers 1 and 2, one of the chucks being moved axially by a suitable cam 18. Attached to each of the chucks is a roller 21- adapted to contact at an appropriate time with cam rails 22,22,

. the seaming ring 11 is adapted to perform fixed upon the frame of the machine. The

cam rails 22, 22 "act to bring the chucks,

and the can bodies and ends held between the chucks, into working contact with the seaming ring 11, which, as heretofore explained, is rotated-by suitable driving means upon the carrier 1. As the carriers 1 and 2 carry the can forward the first seaming operation is performed. 'When this first seaming. operation is completed the rollers 21,

come'into contact with other camrails 23, 23, upon the frame, which shift the chucks and can bodies held thereby to bring the can bodies and partially seamed ends thereon into operative contact with the seaming sector 15. They seaming sector 15 then acts to perform the second seaming operation and complete the seaming of the head upon the can body. It will be understood that the chucks are rotatably mounted in their supports and hence allow the can bodies and ends to turn when they are in contact with the seaming ring 11 and seaming sector 15.
