I m a cr b/7 ers lw it known that l. Jiurs lirnlzzuznrn, a ririr i'n of the lfnilcd States, l't'ril llllg at .ii'ounl viii-non, in the county oi ivcstchcs icr and State, of New York, have invented rrrtain new and usci'ul lmproicments in l ooi-(arrici for (andloading hi. .incs, of \ihich the following is a spoeiiication.
This invcntion relates g cnerally to machincs l'or sccuring tho cud portions to the body portions of shectinctal containers, coniuimily known as tin cans. by what is known as tho doublo-seaniing process. and more partizularly to impriwcnicnts in the, manner of mounting and carrying the scam in g" rollers.
it i roiirsc obvious to any our skilled in tin art that tho seaming roiicrs of a doubic raining llilifihlllf, particularly when thc lsI- s art oivcd around a stationary clinch. :ronirc a certain n ccty of adiustmerit in. ulWl l lo pit'riorm. lb ir proper i'unc- \viuic :uinstmcni, must be or sci of operations, (hare slu'uld not too great rigidity in view of zcr sli variations in the sizes of thc parts o ciulcd upon and not perfect; uniforn'iity in sheet metal ap'ainst which thcsc roll c Furllicraiorc, particul rly \i'hcrc sing; c slanting machine. employed for landing cans of diliercnl; sizes, dilliculty is experienced with prcscni types of machines in adiusiin tho san'io for the; hon ding of cans of dili'ei at dimcn. us.
Tho principal objects of the. pres-( nt invcntion are, first, tho prov sitm of a roller-- carrier which may bc casily and readily uionnicd in and rci'raivcd from the ma hine. alivr l'rv tlirou h ihc provision of carriers toms. rm

Fourth. to simplify generally prcsrnt methods of mounting these seaming rollcrs.
'"ll'lPlOYt-ll for purposes of adjustment, as
hereinafter described; Fig. 5 is a bottom plan view of Fig. 2; Fig. (3 is a top plan view thereof, partly in section; and Fig. 7 is a detail plan view of the device for clamping each seaming-roller aXlc, as hereinafter described.
There, are two general ways in which the double. seaming operation may be performed, one being that of rotating the chuck and therewith the can body and subjecting the can parts to the action of the seaming rollers which are brought into and out. of coopcrativc positional relation to the same, and the other by revolving the seamingrollers around a stationary chuck. T his last mentioned method is preferable for many reasons, not least among which is that of preventing the discharge of the contents of an over-filled can due to centrifugal forces generated by the rotating can body prior to the clamping of the cover thereon, and also because this type of machine is better adapted to be used in connection with devices for automatically feeding the assembled can parts to the seaming mechsnism.
\Vhcre the chuck is rotated and the rollers are brought successively into cooperativc relation thereto, it will be apparent that the adjustment of the rollers does not inolvc any very serious difficulties, While ivhcn ihc rollers arc revolved around a. stationary chuck. it becomes a much more difficult propc ition to scours and retain a propcr adjustment.
It will be apparentthat my invention may be tmploycd in connection with many dilicrout. types of" machines in which the seaming rollers are revolved around a stationary chuck, but I have selected for purposes of illustration seaming mechanism which includes a stationary shaft 11 carrying at its lower end the usual chuck 12 which cooperates with the seaming rollers in a well known manner to double-seam the can tops to the bodies of the cans. Rotatahle on this shaft 11 is a sleeve 29, terminating at its lower end in a circular eccentric 32 upon which is journriled a seaming head 13, each 0? these elements being either positively rotated in the same direction at slightly different velocities. as fully shown and described in my eo-pending application. filed July 5, 1910, Serial No. 570,343., or the seam ing head 13 is held against rotation. while the shaft ll being rapidly and the sleeve 29 relatively slowly rotated in the some direction, as fully shown and described in another two-pending application filed June- 7, 1911, Serial No. (731.752, whereby the relative position of the seaming head with respect to the shaft 11 and chuck i2 is periodi cally varied for the purpose of periodically bringing the seeming rollers successively into and out of coiiperative relation to said chuck. As this mechanism and its operation are shown and described in detail in my copending applications aforesaid, it will be unnecessary to describe the same in detail in connection with this application.
Mounted within or carried by the seaming head 13 is the ring lat. This ring is split, as shown in Figs. 2, 5 and 6, and is preferably secured to the seeming head 13 at two points. as indicated, through the holes 15 and lo, the former 'heing located adjacent to the split 17 and the hitter substantially diametricnlly opposite thereto for the purpose of giving substantial rigidity to that section of the ring upon which the first operation seaming roller 18 is mounted, and more or less resiliency to the other ring section upon which the seeondoperation seaming roller (not shown in the drawings) is mounted. As shown, each of these seaming rollers is designed to be located near one or the other of the contiguous ends of he ring 14, and for purposes of adjustmen. I. hate shown this ring provided with removable eoeentrio bushings 19 Within which irremounted the axles 20 and 21 of the seeming rollers. I have shown each of these bushings provided with a head 22, hawfing the circurm ferential groove 23, for purposes which will he hereinafter explained, this head providing the means for rotating this bushing and thus varying the relative position of the seaming roller with respect to the ring 14. The head is also preferably provided with an annular series oil apertures 30 for the in sertion of a pin to facilitate rotation of the head and pushing. The bushing 19 is also splitthl'oughont the major portion of its length. ss indicated in Figs 3 and 4, these splits 3: and fill being prefershly located 4.). inetri'itelly 4 posits each other. lint-erwe ting the bore in which the eeeentrio hush-- ing 19 is located is a transverse here Within which is the pin 24, which is provided at outer end with the screw thread for the reception of the nut 26. This pin is provided with the circular recess 27 into which projects a portion of the bushing 19. It will be apparent that it through the nut 26 the pin 24 forced in either direction, it will operate through the. yielding imshing sections to rigidly clamp the. axle El or" the seaming roller within the bushing l in wl'mtever 7 rotative position the latter may occupy. l. have also shown it clamp 31. one end of which is adapted to er the groove :23 in the bushing; he l ;E the screw is ndnpt+; \i to s rigidly against the 3e of the ring double clamping it" the pairp initting the removal the rollers axles without distmhing the nrljnst the bushings. Oi nearer, the pin 5% nnist l moved to free the bushing l9 before the trio 21 of the roller can he withelrnwn and do? ing this operation the clamp plate 31. continues to clamp the bushing head and hush-- ing in its adjusted position. The bushing it so self may he removed by loosening the pin 24 and withdrnwing the plate iii. it to he understood, of course, that the other h hing, bushing hood. seaming roller ehnnping means are identical tin described. e pt that the working pip! .fl eral groove in this lnst-opemtion" or -:.:orn-

In availing fflft'f'wif of the prov-extents and sdventm angemeni oi s shown and )1 g 1 W5 plieotions of i that the seeming rollers lo emnpo.mtirei close pron then it follrms there to rel i that I can. owne ad 3 m sulting from roller yieldingly iimimnt h n U tively positioning "the re on the ring is. that the split 1? in Said will be inter posed between said roliers--or between the firstrmerntion" roller and the last-opera tion roller, if more than two rollers are on ployed-end securing said ring; to the sennb ing head 13 in the manner deseril'ied. Furlocating: these rollers in elose therrnore in proximity to each other. particularly in :i t
machine in which these rollers are l" go e to he revolved are" "i the can parts, 1
---if not ootiiinlly es sentiel to tion of 1 ing operzri. of these rol the seeming lion-i pie.
izie 36GUZ1g hinge 33 on the side 'ukecombination, with a scnnnng head, means ioness it will be apcuv a carrier for ..h y U15 readily 'attached tovand detached from the seaming head, in which rollers can be easily and readily adjusted and which, when once adjusted, will retain.- such adjustment indefinitel y or as long as mey be desired. It will furthermore be apparent that with the pro vision of one of these rings for each perticular size ofcan in connection with the head ing of which it is desired to use the machine, the latter may be very readily and quickly adjusted for eny regular size of can desired. It will furthermore be apparent that the provision of a split ring, secured to the seaming head in the manner described, prorides the neccssa r" rigidity to the firstoperation seaming roller, which merely has the effect of bending or curling the super posed flanges of metal, and the necessary resiliency to the second-operation seaming roller, which compresses folded layers and therefore acts upon substantially solid metal which may very slightly in dimensions, as
suggested.
Many modifications oi minor details in my improved seaming ring will doubtless readily suggest themselves to those skilled in the art to which it appe'rtains, and I therefore do not desire to limitmy invention to the specific construction herein shown and described. v
