Figure 14 illustrates the action of the the top taken spinning rollersduring the sealing operation.

Heretofore in the art it has been customary to form side seals on glass containers or the like by means of sealing chucks wherein the skirt of the cap was deformed throughout its entire circumference simultaneously between underand upper jaws of a compression chuck which was operated by powerful mechanism to perform the deforming operation and compress the gasket. 'In this type of machine it'is necessary for very heavy pressure, amounting to several thousand. pounds, to be exerted simultaneously over a relatively small area. This enormous pressure on the relatively small area on the chucks tended to rapidly wearthe chucks so that after a relatively short time thechucks were incapable of making as strong a seal as when the chucks were new. Furthermore, the simultaneous compression ofthe entire gasket around the glass tumbler. or similar container prevented any adjustment or yielding action of the gasket in the bead of the cap, with the result that glass which was defective by being out of round or improperly annealed was often broken.

Furthermore the construction of such machines demanded that the partsbe arranged to sustain very heavy forces and it was the custom to construct such machines as a complete entity so that a breakor wear in any part of the machine meant the dissembling of the entire machine sufficiently to reach power plant and in the line-shaft of the factory.

Another undesirable element sometimes encountered in machines of the chuck-variety was the fact that the metal forming the skirt of the cap often tended to wrinkle rather than flow as was desired to form the seal. This was due to the fact that the entire skirt of the cap was simultaneously being subjected to sealing forces, thereby preventing the relief of stresses in any direction.

The present invention overcomes the difliculties of the known art by providing a machine wherein the sealing is adapted to be v I gradually, there are no undesirable surges in the power required. Furthermore, since the.

sealing force is applied locally, a very much less power is required for the sealing operation' than is necessary to operate a chuck type of machine, because only a very small portion of the bead is under operation at one time. In view of the fact that the forces are locally applied to the bead of the skirt over the gasket there is an opportunity for the metal in the skirt to yield in'other directions and this obviates wrinkling of the seal and very greatly overcomes wear so that the same mechanism may be used for a relatively long period of time to form good seals. Furthermore, 'since the sealing operation occurs locally, it is a very easy matter to adjust the position of the sealing rolls to compensate for wear. This-is not possible in a jaw chuck, where the jaws comprise continuous rings as has been'common in the art.

The present invention also overcomes the difliculties of the known art by providing a construction wherein 'the machine is built in unity groups so that in case of any disablement of a member in a particular group repair or replacement may be accomplished easily byremoving the group and substituting a new unit which may operate while the defective unit is being repaired. I Further more the replacement of parts as units facilifed because. it was not feasible to move automatic feeding mechanisms each time the machine table was raised or lowered. The present machine obviates the difficulties of the known art in this particular by providing adjustments through which the spinning head may be raised or lowered without even stopping-the running of the machine. This is an adjustment of great importance in the ordinary packing factory where one machine may from time to time be required to seal many different sizes and types of packages.

The machine of the present invention in a general 0 tline comprises a. main frame adapted to arry a power. unit such as an electric motor geared to a suitable clutch and all mounted on an auxiliary frame with a drive gear carried by the drive shaft and extending beyond the frame. This mechanism is adapted to be manufactured, assembled, and dissembled as' a unit, which greatly facilitates these operations. The

main frame is provided with an upper and lower section, with the main drive gear mechanism in the lower section and with the upper section comprising guide members or supports for the spinning mechanism as will later be described. A pair of concentric hollow shafts are vertically mounted in the main frame and are adapted to be driven action against the gasket. "Prior to the beby the driving gears. The upper spinning head and operating devices are mounted in the upper part of the main frame and are vertically adjustable on guideways carried by the upper half of them'ain frame. The adjustment may beaccomplished by a'supporting screw shaft carrying a suitable hand wheel, the turning of which'raises or lowers the spinning mechanism and a transverse clamp which is operative to clamp the spinning head frame tightly against the guides to maintain the parts very rigidly supported in 1 any adjusted position. The spinning head which is carried on the spinmng frame comprises spinning rolls, mounted on cam controlled swinging arms. The spinning head rotates continuously, so long as'the machine is running, around a. sta tionary anvil adapted to engage the top of the bead of a cap. A stationary cam is carried by the anvil andis adapted to gradually move spinning rollers radially inward so that the spinning action is a compression ginning of the spinning action a container has been moved forward by the package transferring mechanism and as the container passes beneath the cap feed station a suitable cap having a bead with a gasket in the bead is dropped into position over the container. The container then moves forward and is stopped upon a spring su ported table., The next operation is the lifting of this table by a suitable cam so that-the head of the package is carried through a guiding funnel and the cap is brought into contact with the cap retaining head. This head is controlled by a cam mounted on one of the .vertical hollow shafts and while the. head recedes another cam on the same shaft descends until the anvil rests on the u per edge of the bead. As the anvil comp etes its downward movement it' slightly compresses the spring beneath the supportingtable and when this action begins the spinning rollers may move radially but not vertically, are gradually brought inward.

The spinning action is a progressive action which begins at the lower part of the cap bead and gradually moves in an upward and inward direction, so far as the head is concerned, due to the fact that the anvil is moving downward and the downward movement of the anvil carries the rotating spinning rolls inward. This action produces a very tight and efficient side seal and the cross-section of which may be varied to suit circumstances, but in the preferred form is of a general triangle shape.

From the foregoing it will be noted that the machine comprises a mam frame upon which are mounted three auxiliary groups,

namely, the driving mechanism, the splnning head, and the package feeding mecha- Dfim'ng mechanism.

ed to be attached to themain frame of the machine and carries a supporting frame 2 on which-an electric motor 4 is supported.

The drive shaft 5 of the -motor carries a small gear 6 which meshes with a large gear 7 that carries driving plates=of plate clutch 8. This large gear is loosely mounted upon a tubular drive shaft 9 and is supported against thrust by a ball-bearing 10. The tuturn the machine by hand for inspection or otherwise. A slida-ble collar 12 carries the driven plates of the plate clutch 8 and bular drive shaft 9 carries at the outer end l .a hand wheel-'11 which may be utilized to 120 forms the pressure member by means of Y which the plates may be pressed together so as to transmit power from-the:- motor to the main drive shaft. The clutch l's'operated by a bell crank 14 which is connected with a lar pivoted in the arm 16 which is mounted- 'to rotate on the stub 17. A compression spring 18 tends to place the link 15 under tension when the'hook 19 is looked over the dog 20 on the arm 16, as shown in Eigure 12. When the operating handle 21 is moved toward the link 15 the extension 22 thereon engages a similar extension 24 on the arm 16, thereby causing the arm 16 to swing counterclockwise to compress the spring 18 until the hook 19 has dropped over the dog 20. This causes the connected parts to operate the slidablc collar 12 to tightly clamp the plates of the clutch 8 together so that power from the motor shaft is transmitted to the main drive shaft. When the operating handle is pulled away from the link 15 the release face 25 engages the dog 26 on the hook 19 and raises the hook 19 clear of the dog 20, thereby releasing the arm 16 and permitting it to drop under the influence'of the spring 18 and weight of the connected parts so that which reference will now be made.

the clutch 8 is opened and the machine stops. Referring now to Figures 2 and 3 the inner end of the tubular drive shaftis closed by the plug 27 so that the shaft may be utilized to carry lubricant which is conveyed into the

various bearings

28', 29 and 30 through small holes in the shaft 9. The inner end of the main drive shaft carries a u raw hide silent gear 31 adapted to mesh with other suitable gearings, as will be later explained. It will be noted that by removing the base 1 from the supporting frame and disconnecting the link 15, that the whole of the power plant may be removed as a unit and replaced with such other drive mechanism as may be desirable or necessary either when making changes or for purposes of repair.

Pedestal frame and vertical shaft. J

The main frame or pedestal frame and mechanism carried thereby is illustrated more specially in Figures 1, 2, and 3 to v p The. main base frame 101 carries the intermediate main frame 102, and the upper supporting main frame 103 and also forms the support for the

frames

1 and 2 of the driving mechanism previously described. The base frame 101 is provided with a shelf 104 on which is mounted a lower gear frame 105. This gear 7 frame carries a stub shaft 106 substantially parallel with and in the same-horizontal plane as the main drive shaft. A gear 107 on the stub shaft 106 is in mesh with the raw hide gear-31 on the main shaft. The stub shaft. carries a worm 108 which is in mesh with the worm wheel 109 on the vertical line shaft 110. This vertical line shaft is relatively slow moving and carries on each end certain cam members. The upper end of the line shaft 110 carries the spinning head cam llland the lower end carries table lift cam 112'. This balances the torsion onth'ezshaft.

neoaeee line shaft 110 is likewise hollow with the ends plugged in a suitable manner and thereby comprises a'relatively large reser voir for lubricant which may feed through openings (not shown) to the shaft bearings.

A bracket 116 is mounted upon thelower gear frame 105 substantially'over the raw hide gear 31 and comprises a bearing for a short shaft 117 which carries on one end a gear 118 in mesh with the raw hide gear 31. The other end of the short shaft 117 carries a bevelled gear 119 which meshes with a raw hide bevelled ear. 120 that is mounted on the lower end 0 a tubular vertical main shaft 121 which surrounds and-encloses a portion of the vertical line shaft 110. The main shaft 121 is supported at its lower end in a bearing 122 formed on the lower portion of the supporting frame 103 and at its upper end in a bearing 124 formed in the head frame 125 which is vertically movable relatively to the supporting frame 102. A raw hide gear 126 is mounted on the upper end of the main shaft 121 in a space between the bearing 124 and the base of the housing 127 for the spinning head cam 111. The lower end of the spinning head cam is enlarged to revolve around a guiding collar 128 and'the spinning head cam 111 is hollow. This spinning head cam is attached to the line shaft 110 by a slidable key-way connection and the raw hide gear 126 is similarly attached by a sliding key-way connection to the main shaft 121. A vertical adjustment screw 129 extends through a portion of the head frame 125 and engages a nut 130 mounted between extensions on the head frame. The upper end of the vertical adjustment screw is provided with a hand wheel 131 so that the adjustment screw may be turned and the head frame raised or lowered in order that the spinning devices will be at the right height to form hermetic seals, as will be later explained. During this raising or lowering movement of the head frame 125 the spinning head cam 111 and the raw hide gear 126 slide on their respective driving shafts and the main shaft 121 may have a telescopic movement through- -wheel 137 whichpermits-the head frame-to be tightly clamped against the

guides

132 and 133 so that the parts are rigidly held in adjusted positions. After the parts have been duly clamped the lock nut 138 is set to.

hold the parts securely inposition.

Spinning head.

The spinning headmechanism which is illustrated more specially in Figures 1, 2, 6, 7, 8, 9, and 14 comprises vertical spinning shaft 201, carried in the head frame 125, and provided on its upper end with a gear 202 in mesh with the raw hide gear 126. The lower end of the spinning shaft 201 carries a rotating plate 203. This plate forms the support for the arms which carries the spinning rolls 204. These arms are formed in two

parts

205 and 206. The part 205 carries the spinning roll 204 and the part 206 carries the guide roll 207. The

arms

205, and 206 are associated with each other by means of a collar and sleeve construction consisting of a collar 206*. which is preferably integral with arm 206 and a sleeve 205 which is preferably integral with arm 205. The collar on the arm 206' is clamped around the sleeve on the arm 205 by means of clamp bolts 208, .and' the composite element thus formed is pivoted to rotating plate 203 by a bolt 213. This construction permits an adjustment between the guide roll arm' and the spinning roll arm so that the spinning head may be adjusted to accommodate caps of different diameters. A spinning anvil 209 is mounted on a tubular member 210 to which is connected the roller head 211 that carries the, roller 212 which travels-in the cam groove'214 in the spinning head cam 111. This roller head 211 comprises a guide which slides in guide-ways 215 (Fig. 1) provided on'the housing 127 forthe spinning head cam 111. A cap holder 216 is mounted on the lower end of the rod 217 which reciprocates through the member 210 and carries upon its upper end a roller head 218 which is provided with a roller 219 that cooperates with the upper cam groove 220 in the spinnin head cam 111.- The rollerhead 218 (see igs. 1, 6, and 7) is adapted. to shde in guide-ways 221 which are'formedon the roller head211 so that this member is eifectively supported during its operative movements. The rotative plate203 carries posts 222 (Figs. .8 and 9) which form supports for coil springs 224 that bear against the parts 206 of the spinning arms whereby the guide rolls 207 are normally positioned against a guide collar or temp et 225 (see Figs. 2 and 6) which terminates in cone cam 226. The spinning head .is enclosed in a casing 227 which is provided with a removable guide funnel 228. This. guide funnel 228 is adapted to position the mouth of 55.

a jar with a cap thereon directly in the path maintain the be ts taut. The

of the cap holder 216 so that the anvil 209 will properly engage the head of the cap to enable the sealing operation to be completed. The casing 227 and housing 254 are each split in a plane parallel to the paper in Figure 1, and by removing

cap screws

250, 251,

252, and 253, the entire spinning-mechanism may be removed as a unit, including the spinning rolls, anvil, gear 202, and cam rolls .212 and 219.

Package feed mechanism.

shaft carries at its up er end a bevel gear 1 305 that meshes with evel gear 306 shown in dotted lines in Figures 4 and 5. The

bevel gear 306 is carried by a cross shaft 307 which is mounted in bearings in the table support frame308. This cross shaft 307 carries a sprocket wheel 309 upon which is mounted the package feed chain 310. This package feed chain extends substantially the length of the feed table and passes over a sprocket wheel 311 near the outer end of the table. This sprocket wheel 311 is likewise mounted on a cross shaft 312 that is joumaled in bearings near the outer end of the table frame. The cross shaft 312 carries a gear 314 which meshes with corresponding gear 315 on a short shaft 316 on which is mounted worm 317 (see Figs. 10 and 11). The worm 317 engages the worm gear 318 on'the short vertical shaft 319 that carries the spacer plate 320, wlnch is provided with package pockets 321. The op 0- site end of the cross shaft 312 1s prov ed with a gear 322 that meshes with an idler gear 324 which drives a belt shaft 325. A pair of

belt wheels

326 and 327 are mou ted on the belt shaft and carry conveyor its 328' and 329 that extend forwardly over ulleys 330 and 331 mounted on the idler s aft 332. A belt ti htener 333 is provided to ackage feed chain 310 is provided at su'ita le intervals with package engaging lugs 334 which are spaced in timed re ation with the package pockets 321 on the spacer, plate 320. A sult- -able bed late 335 is provlded for the pack ages to side uponand is formed wlth a the packages while being moved under the v influence of the packa e engaging In 334. It will be noted that t e conveyor be

ts

328 and 329 are spaced apart on each side of the package feed chain 310 and the linear speed of the conveyor belts is substantially the same as the linear speed of the package feed chain. The drive for the spacer plate, the conveyor plates, and associated parts, comprises the package feed chain which is positively driven by the sprocket wheel'309 on the cross shaft 307. The cross shaft 307 (Figs. 1 and 4) is provided with a spiral gear 340 which meshes with the spiral gear on the connecting shaft 341. This connecting shaft 341 is also connected by means of spiral gears 342 and 344 (Fig. 11) with the cap feed shaft 345.

The cap feed (Figs. 1, 10, and 11) is operated by cam 346 mounted on the shaft 345 and cooperates with a roller 347 on the end of a lever arm 348. The opposite end of the lever arm is provided with a spring 349 which normally maintains the roller in contact with the cam and upwardly extending link 350 is connected to the lever arm adjacent the spring. The link 350 operates cap releasing mechanism 351 which feeds a single cap from the cap supply 352 and causes the fed cap to move downwardly to the cap applying mechanism 354, which is operated by the star wheel 355 (Fig. 11). This cap applying mechanism is described in general terms, only, for the reason that it forms the subject matter of a separate and independent application for patent S. N. 375,240, filed April 20, 1920. The hand wheels 356 are connected with short shafts 357 that carry crank arms 358, on which the track 359 for the package feed chain 310v is mounted so that this chain is vertically adjustable as may be required. This permits adjustment of the height to which fingers 334 project above the table, and permits adjustment to compensate for wear of track 359, and the chain 310. The traekis secured in the adjusted position by means of set screws 390 which pass through the collar integral with the frame work and engage I shafts 357 that carry the crank arms 358.

Table feed.

In the present machine when packages arrive at the end of the travel of the package feed conveyor the packages vare removed from'the conveyor and positioned upon a rising table directly beneath the spinning head so that packages may be raised into the active zone of the spinning mechanism and i the seal formed accordingly. This table feed spring 416.

the head and are controlled by a stationary cam 407 against rollers 408 carried by the finger control arms 409. These rollers 408 are held in engagement with the cam 407 by means of the springs 410. The intermediate fingers 411, while being adjustable on the head 405, are nevertheless stationary after the adjustment is made. As the head revolves the movable fingers 406 swing outwardly to pass the end of the package chain 310 and these fingers are mounted in timed relation with the package engaging lugs 334 so that any package being moved along by a lug 334 on the chain 310 will be engaged by a finger 406 and swept around over the bed plate 335 until the roller 408 drops from the cam face 412 of the stationary cam 407.

When this happens the movable finger 406 loses control of the package and the package is left standing stationary. The next succeeding rigid linger 411 following picks up the package after intermediate operations have been performed thereon and carries the package onward.

When the package is left standing by the movable finger 406 it is positioned directly over the vertical movable table 414. This table (Figs. 2 and 4) is mounted upon a telescopic shaft 415 which is normally maintained in extended relation by means of the This shaft is adjustably connected as at 417 with a slidable bar 418 mounted in suitable guide-ways 419 and that carries at its lower end a roller 420 which is adapted to follow the table lift groove 421 in the table lift cam 112. The parts are so timed that immediately after a package 339 has been left stationary on the table 414 by movable finger 406, the cam groove 421 becomes operative to lift the bar 418 and connected parts thereby raising the head of the package through the guide funnel 228 in the spinning head casing 227 thus bringing the cap into contact with the cap holder 216 which has been moved downwardly to meet the cap. After contact with the cap. the cap holder recedes and the anvil 209' moves downwardly until the rim of the anvil rests upon the head of the cap. The continued downward movement of the anvil member causes the spinning rolls to be swung inwardly so that the rolls spin the head against the side wall of the glass member of thepackage 339 and thus form a hermetic seal. As soon as the spinning operation is finished the table lift groove 421 in the cam 112 has reached such a position as to cause the package table to lower-and when the package table has dropped to the position shown in Figure 2 a rigid finger 411 engages the package and sweeps it from the package lift table.

Regardless of the diameter of the packages being sealed it is desirable that they be centered with respect to the sealing mechanism, and since the conveyor lugs 334 and the

flights

406 and 411 engage the periphery of the containers, provision is made for advancing and retarding the timed move- 5 ment of these parts with respect to the rest of the apparatus in order that they may properly position containers of different diameters. The advancement or retardation of the rigid flights 411 may be effected by manipulating nuts 481 and adjusting the flights individually. The corresponding adjustment of the movable flights 406 is accomplished by loosening nut 482 and shifting arm 483 thus adjusting the angular positlon of the stationary cam 407 which controls the operation of the movable flights. Advancement or retardation of the conveying lugs 334 is effected by manipulating.

bolts 360 and adjusting the angular position 2 of sprocket wheel 309.

Take-0;) mechanism.

The take-ofl mechanism for the sealed packages is shown more specially in Figures 1, 4, and 5 and comprises a conveyor belt 501, which is supported on driving pulley 502 and idler pulley 504. The driving pulley 502 is mounted upon a cross shaft 505 which carries a spiral gear 506 that is in 30 engagement with a cooperative spiral gear 507 on the connecting shaft 341, which forms the drive connection for the driving shaft 505-. The conveyor belt is provided with belt tightener 508 to maintain, suitable tension of the belt, and which belt tightener is mounted upon the take-off frame 509 which is bolted to the main frame of the machine. Suitable package guides 510 are adjustably mounted adjacent the path of the sealed packages in such manner that the packages will be maintained upon the conveyor belt, while bein carried thereby. The packages come on to t e conveyor belt from the lift table in spaced relation so that they may be conveniently removed by operators or mechanism for packing for shipment.

Finished package.

- Referring now more especially to Figure 14, when a package 339 with a cap 601 thereon is raised by the package table 414 and is engaged by the cap holder 216, the table continues to rise and the spinninganvil 209 descends. After the rim of the anvil engages the top of the bead 602 the table continues to rise until the coil spring 416 is slightly under compression so that the bead 602 is lightly pressed against the rim of the anvil. This not only steadis the package and provides an anvil to spin the bead against but it also holds the package stationary. The vertical spinning shaft 201 rotates continuously while the machine is running thereby carrying the spring'rolls in an orbital path around the axis of the shaft 201. The anvil continues to descend in the direction of the arrows A, and the guide rolls 207 engage the cone cam 226 thereby swinging the roll carrying'arms to bring the spinning rolls 204 into engagement with the lower part of the bead 602. As the anvil continues downwardly the motion described progresses and the spinning rolls have an effective inward and upward movement against the bead 602 in a direction of the arrows B as well as the orbital movement, thereby spinning the metal in the bead of the cap inwardly and progressively compressing the. gasket 604 so that a very tight hermetic seal is formed against the sidewall of the glass tumbler 605; After the anvil 209 has been retained in its lowermost position until the spinningrolls 204 have made such a predetermined number of revolutions on the bead 602 as are sufficient to complete the seal, the anvil rises, and in rising the cone cam 226 moves upwardly relatively to the guide rolls 207 thereby causing the guide rolls to swing the roll carrying arms in such manner as to remove the spinning rolls 204 from the bead 602 so that the package is left free to descend with the downward movement of the package table. When the package table reaches its lowermost position the package is removed there ifrom in the manner previously described.

From the foregoing it willappear that the machine of the present invention is designed in unit groups of mechanism which when properly assembled form a completed whole adapted to automaticallyfeed packages; place caps thereon; seal the caps on suitable containers; and then deliver the sealed containers in spaced relation for packing or labeling.
