To @ZZ 'w71 om it may concern f I I Be it lvnoivn that l, Perma Kauen, a citizen oi the United States, residing at Brochlyn. county ot Kings, and State of New York, have inyented certain new and use :lul Improvements in Boubleleaming Machines, of which the following is a specification.

This invention relates to a machine for producing sanitary cans and more particularly forsecuringthe head or cover to a can body by means of a double seam in a novel. quick and eilective manner.

Briefly stated the invention comprises a pair of. concentric seeming rings :if coniparatively'large diameter and arranged in a common plane. the radial distance between said rings being somewhat larger than the diameter et they cans to be scaled, so that the lattervcan be inoperative engagement with but one of said rings at a time. These rings or annular seamers receive continuous rotary movement in opposite directions While the cans together with their covers are freely rota table between said rings and do not receive any `positive rotary movement what soever. During operation, the means for supporting the cans are automatically moved toward one of the rot-ary rings so that thc cans engaging said' ring will. be rotated on their axes during which operation the lange of the can head is curled about the liange ot the can body. This operation be completed, the supporting means are moved toward the other ring ythat rotates in the opposite direction. so that the preliminarily seamed cans, after their engagement with the second ring continue to rotate in the same sense as before, the second ring' compressing or flattening out the seam so as to provide the desired tight closure for the can.v The invention` also cor'nprises numerous other novel features of construction as tion and claims.'

tu'llv brought out vin theannexed speciiea- 1 ln the accompanying drawings Figure l.

' is a side view partly in section of ay double scaming machine embodying my \invention;

the seam as linished by the closing ring.

ifi ithin a pair of standards 10, ll forming part oi.E the machine trarne, is iournaled a horirionta-lly extending main shaft 12 vwhich receives rotary movement from a driving pulley 13 loosely7 mounted upon ashaft lfi. l

Pulley 'i3 is adaoted to be coupled to shaft 14- by a clutch l5 operated by hand lever 16 which shaft in turn, transmits motion through a train of lf? to the main shaft l2. Upon the latter are irmly-niountczd the hubs 18, 19 of a p. or" opposed circular cen'carriers 20, 2l., respectively. 0f these. carrier 2Ol shown to have the vadditional function of rotatably supporting two concentric seaning rings 22, 23, arranged in a common plane. @ne of these rings, say ring 22 is so profiled as" to curl. the flange 24, of the ycan head 25 about the flange 26 of the can body 27 (Fig. 8), while the other ring is profiled forrcompressing or tightening the preliminary formed by ring' 22 (Fig. ill. whereby the desired hermetical sanitary can seal obtained.

.is clearly apparent iii/fordl 23 exceeds the outer diameter of the cans ring 22, it clears ring 23 and vice versa.

Figs. l and ,7. the radial distance between'theu rings 22,

The means for rotatably supporting. the

can' bodies ltogether with their heads and for consecutively presenting them to the ac tion of seamers 22, 23 are as follows I f Carrier 2G is provided with a plurality 'of-say six-oblong openings 23 surroumft.

adjusted by a pair of set screws or other-VV ed by similarly shapedr bosses 29.l vlilithin each opening 2S is radially movable a slide 30 which is guided h v gibs 3l. Each slide 30 is in turn pro'videdrwitl'i an opening 32 adapted for the reception ot' a bearing block J3, which is guided along gibs 34 secured to both sides of slide 30, and may be radially wise.

Block is provided with a central bore 3G that extends in parallelism 1Vith shaft l2. Within this bore is slidably mounted` a, spindle 37 between a lixed collar 38 of which and block 33, is interposed a coiled spring tending to force spindle 37 toward carrier 21, this movement of the spindle being limitedby a collar 40 of the spindle. To the latter is `rotatably secured the lub 4l of a disk 42 adapted to engage the recessed can head 25 (Fig. 7), between said hub and spindle 37 being interposed a ball race 43.

Carrier 21 is in similar manner provided with six openings 44 alongeach of which is movable a slide 45 guided by gibs 46. A central opening of this slide accommodates a bearing block 47 which is radially adjustable by set screws 48. `Within a bore of block 47 is axially slidable a spindle 49 earrying at. its inner end a disk 50 that is adapted to engage the bottom of a can, a ball race 51v being interposed between said disk and spindle.- At its outer end, spindle 49 carries a cam roller 52 adapted to engage a stationary cam 53 attached to standard 11, the cam roller being forced toward said standard by a spring 54. It will thus be seen that as lon as roller 52 rides along cam 53, acan 2 and its head 25 will be firmly clamped between the freely rotatable disks 42, 50 (upper part of Fig. 1), so as to permit the seam.- ing operation to be properly performed, as

will hereinafter be morel fully described,

j (rig. e).

while upon leaving said cam (lower part of Fig. 1), disk 50 is retracted in order to permit the discharge of the scarned can and the introduction of a fresh can to be seamed.

The cans together with the heads loosely applied thereto, are shown to be ted through a chute -55 to a recessed turret 56, a curved guard 57 keeping` the cans in engagement with said recesses during the rotation of the turret in the direction of the arrow a Slightly prior to the arrival of a can in horizontal alinement with main shaft 12, cam roller 52 will ride along the bevel 58 of cani 53 to finally clamp the can and its cover between disks 42, 50. Immediately after a cann has thus been properly grasped, the two coperatinu slides 80, 45 are unisonally moved toward the preliminary searning or clenehing ring 22. The latter is firmly secured to a flanged ring 59 having a tapering inner rim 60 that is rotatably held to carrier 2O by means of a correspondingly tapering guide ring 61 attached to said carrier in suitable manner. Ring 59 is furthera toothed reversing wheel 63 loosely mounted in a bracket 64 that also supports the 60 inner'end of shaft 14. 'loothed wheel 63 engages in turn a similar wheel 65 fast on shaft 14, so 4that vcontinuous rotary movement is imparted to seaming ringQ.

he means hereinabove referred to tor moving slides 30, 45 toward seamer 28 ecmprise essentially a substantially quadrantal cam 66 adjustably secured to the inner face of standard l0, and provided with a beveled end 67. One end of cam 6G is perforated as at 68 for the reception of an eccentric headed collar 69 of a threaded pin 70 having a squared end 7l andy adapted to be tixed in the position to 'which it has been set, by clamp nut 72. To the other end of cam 66 is connected the eye 73 of 'a screw bolt 7 4 loosely passing through a perforated lug 75 of standard 10 and held in position by clamp nuts 761-10511; 66 is adapted'to be consecutively engaged by the cam rollers 77 ofsthe several slides 30, cam rollers 77 being rotatably supported by the radially extending arms 78 of said slides (Figs. 1 and 4). In like manner, standard 11 is provided with a quadrantal cam 661 between which and the standard, is interposed a spacing segment 79 so as to expose the cam 661 in front of cam 53, the means for radially adjusting cam 66l being in all respects duplicates efthe means described in conjunction with cam 66. Cain G61 is adapted to 4be consecutively en- Vgaged by cam rollers 7 7x of the several slides 45 cam rollers 771V being rotatably sup orted by the radially extending arms 80 ov these slides.

'As thus far' described, it will be seen that as soon as a can 27 and its head25 have been properly7 placed between disks 42, 50 by turret-56, disk 50 is advanced by cam 53 toward disk, 42 so as to firmly clamp the can and its head in position while nevertheless permitting a free rotation of said can and head owing to the interpolation of the ball races 43,51 between disks 42, 50, and their respective Sliimllc's. As soon as the can has thus been firmly grasped, rollers 77, 77. engage the beveled faces of cams 66, 661 whereupon they will roll alongI the cam faces 80, 801 ot such cams. so that slides 30, 45 are drawn inward. In Athis way the fiange 24 ot the can head 25 is brought into engagement with. the preliminary scanning ring k22 to curl said flange about the flange 26 of the can body Auntil the flanges have been shaped as illus- 'iat is rotatably held to the carrier 20by a m'oretoothed as at 62 for engagement with In order to bringthc 'can end is connected to av screw hole B8 loosely stircdci'd i0 iiiidedapted to he clamped liii position by nuts 90. Upon the erigegemerit of rollers 7T 771 with coms 8G, 861., slides 30, #l5 are forced outward so as to brins; the cre limiiiarv seem formed by' ring; into erf. ,sagement with Vthe closing' rii'igf The lutter causes zi flattening' or closing of vthe crible uri illustrated in Figa 9 thereby ce' the necessary hermeticsl sanitary ii between the con and its heed.

lo order to insure n subsequent true asiel :iliiiemcrit of the disks en?, 50 with the caosA sis presented hv turret 56, a pair of center` cams 95., 96 aresecured to Standards l0, il h v seresv bolts 97 passing through corresponding slots of the standards sov es to render ssi-id cams adiiistnhle relstivelyto the center of the cari-supporting turretooelrets, und also for the purpose of adapting the machine to cniis ci different diameters.

it will be seen that a machine constructed :is shove described has numerous advantages over the double seeming; machines' heretofore known. Although the carriers for the cans to be seemed simultaneously support s plurality of cans, all of such cans are acted upon hv the same seeming means so as to insure n positively. uniform output. Should :in inspection of thedelivered headedcans show that the seem is either excessively fiattciied or not suliicientlv tight. lthis deficiency may he readily corrected without necessitatiiilgr si stoppingIr of the machii'ien hv correspondingly adjusting the coms (36, G61.
