CAN-END CRIMPING AND SEAMING MECHANISM.

To all -whom it may concern:

Be it, known that LH'NRY C. BLACK, a citizen ofthe United States, residing at the city and county of San- The present inventionismore particularly designed for use in connection with packing and canning estab- `lishments for thehermetically sealing of fruits, vegetables, fish and kindred articles in metallic bodies having theheads and tops secured to the body portion thereof, g Aby,beingcrifmped and seamed thereon, the use of solder for uniting the tops and'bottoms to the body of the cans being dispensed with, the goods thus being sealed in what is known as a sanitary can.

The object ofthe invention is to provide automatically actuated devices for crimping and seaming the tops and bottoms to the can body by a double seamed joint, the'can during such crimping operation being held against rotation.

To comprehend the invention reference should be had to the accompanying sheets of drawings, wherein-- Figure 1 is a view of the apparatus in elevation, illustrating the relative position of the various parts, the vertical drive sleeve for imparting llorizontalrotary travel to the receiving table and to the crimping and seaming mechanism for the cans being sectioned, the said r'eceiving table, the spider carrying the guide sleeves, and the c'aln grooved Aring for the vertically movable plunger 'rods being illustrated in part section; Fig. 2 is a top plan View of the mechanism illustrated in Fig. l of the ldrawiugasaid view disclosing the feed device for supplying the cans'to the rotatable receiving table, an d the means for removingr the cans therefrom after the top or end has been crimped and scamed thereon,l Fig. 3 is a longitudinal sectional top plan view taken on line :hun:

Fig. l of the drawings; Fig. 4 is an enlarged detail 4part sectionalV view of one of the crimping and seeming means for the can head or end, said view disclosing a broken section of a portion oi the yreceiving table and the can. to be crimped and seemed held thereon, the can head or end being applied to the ,end of the can body, the said view illustrating `the position of the crimping roll after having completed .the crimping of a portion of the can head or 4end to the circular fiange of the can body, such, being the first step of the crimping and seeming operation, the first seaming 'roll which acts on the flanged portion o1' the can body being shown swung V outward or away from the can body, the plunger or head on which rests the can to be crimped or searncd being moved upward, to lforce the head or end of the can against the mandrel which holds the can head firmly in position and receives the pressure of the rolls of the crimping means; l'1`ig.5 is a view similar to Fig. 4, of

` the drawings,y illustrating the second step of the crin1ping and seaming operation; -in this view the first seaming roll being illustrated as having partially seamed the flanged end to place the saine at anl inclination to the can body, the crimping roll having completed its work and being moved away from the body of the can;

lFig. G is a similar'view illustrating theposition of the final seaming rolls which force the metal oi the crimpbd and partially seamed end firmly against the body of the can, such being the last step in the crimping and .-.seaming operation; these scamingrolls are not shown in Figs. 4 and 5 oi the drawings, the section ofthe parts disclosed by said viewsbeing taken on such lines as to remove 'the ,said rolls; Fig. 7` is a plan view of one oi the crimping means, said view illustrating the spring connection for holding the/upper portion of the hinged aijms carrying the rolls oi the crimping and seaming means inward, and the vertically movable 'collar for actuating said rolls, the rotating spindle to which said cdllar is feathered and the mandrel stem about which said sleeve rotates axiallybeing sectioned. Fig. 8 is a broken enlarged detail section of a can with its head or end to be crimped and seamed loosely applied th creto; Fig. 9 is a similar view showing the position of the iiange of the can head or end after the action oi the crimping roll, which is the first step of the crimping and seam ing operation; Fig. l() is a similar view showing the position of the ilange oi the can head or end and the flange of vthe can body alter the action of the first scaming roll, which is the second step 'of the crimping and seaining operation; and Fig. `ll is a similar view ol ,the can with its head completely scanned thereto, which is the final step of the crimping and seaining operation.

In the drawings the immoral l is used to designate a central verticalrshaft, to which is keyed-a gear 2. Motion is imparted to this gear for rotatingr the shaft l, by

inea-ns oi the pinions 3, which pinions` are secured to the drive shafts 4.

0n the shalt l isloosely fitted tho-drive sleeve 5, rotation being givcnto sleeve 5 b'y the said pinions 3, which mesh with the gear (i, keyed to the lower end portion oi the said sleeve 5, Fig. l oi the drawings. Thisl sleeve 5 thus rotates axially about the rotating shaft l and the said sleeve imparts rotary travel to the hereinafter described receiving table lor the cans, and

i tho means ior crimping and seaming the can head or vend 1.o the can body held to the rotary impelled receiving table. The drive sleeve 5 passes through a hub 7, upwardly projecting i rom a suitably supported stationary base plate 7, which plate carries the depending brackets 8, which serve supports for the bearings 8" and are connected to the lower bearing 8L for the central shaft l.

To the rotatable drive sleeve 5 is keyed the hub 9 oi the receiving ytable within counterfsunl; circular lll i is

. collar is feathered.

'lindy ol' tho (nn driiwii'igs. lhey continued rot-tion oi the rcceivinty liihlo viruses the roller .15/ to continuo its travel on, i'lic lowiiw-irdly inclined portion ol' the cuin groove l5, drawing the slide collar if) downward, until the edge ol' thc hinged nrni 25 choirs tlicinclined portion 32 thereof, when the tension ol' thc spring ring 26; l'orces the upper cud portion oi' the said tirin 25 inward, so :is to inovc the roller 26 iiwziy troni the criinpod joint oi the held cnn. Art the Sonie time, the upper end oi the hinged :3i-rui 25 is forced outward by the inclined slioul dcied portion 323 oi the griidunlly lowering slide coller lll), lon-ing its lower end inward and causing the first scanning roller 27 to gradually nieve inward toward the can und to pin'tiully force the crimped joint toward thi) 21V, Figs. 5 und 10, of thc drawings. The continued downward movement 0i the .'lide collar lll, cousins thi,- u'pper portion oi the hinged arms 252, to move onto I'he surface 33 of the collar 19, which griidu :ill y inovus inward the lower end of the said hinged arms und cousus the scanning rollers 27 to force the crimped :ii'u'l partially seemed joint'llrruly down onto the body of thc con 23", o, double seemed jointheiug thusviorined, Figs. (l and ll of the drawings. It will be understood that the mandrel 22 resists the pressure of the dcscrihed rollers during the operation oi crimping and seeming the end joint, likewise that duringthe described opc'iition the slide collar 19 is carried around by the rotation of the spindle 1.9/ to which the said As the rollervl/ moves from oli` the di'nvnwiirdiy inclined portion oi the Cain groove l5, and onto the upwardly inclined portion thereof, the li-it rod lo is raised and the slide colla-r 19', through its connection therewith, gradually moves its full upward dis tence, the pressure oi the spring ring 26 restoring the hinged arms 25 sind 252 and the rollers carried thereby, to normal position. The moment the said zirrns'carrying 'the scanning rollers 27/ move awayiron'i the seemed end of the can, the roll i4 moves onto the downwardly inclined portion of the track 14 and the yplunger rod 'll gradually descends by gravity, lowering therewithy its lie-ad l0', until the semned con 23/ is flush with the surface of the receiving trible 9. The scanned can is then engaged by a fixed curved pls-te 33, located at one side ot the 'conveyor 28. This curved plate for guiding the from ol't the receiving table 9 onto the delivery device 28, is arranged-immediately above the sui'- l'ace of, the said receiving table, the seemed cans carried by the said trible striking against the said `piste und being gradually deflected from olf the table 9 onto thc said delivery device 28. i
