UNITED STATES ISIDOR NEWMAN, OF YORK, N. Y.

AUTOMATIC $EA1VIING MACHINE.

Application filed April 12, 1923.

T 0 all whom it may concern:

Be it known that I, Isrnon NEWMAN, a citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Automatic Seaming Machines, of which the fol lowing is a specification.

My invention relates to means for causing tools to automatically advance toward and retreat from articles to be operated upon when such articles are located in the proper position with relation to the tools, and my invention is illustrated in a machine for automatically seaming caps upon metal containers.

In machines for seaming the flanges of caps upon metal containers, such as so-called tin cans, and particularly in such machines comprising rotative rolls or rollers which travel around the margins of the caps to seam the latter to the necks of cans, it has been customary, so far as I am aware. to advance the seaming tools toward the cans or to advance the cans toward the seaming tools while said rolls rotate. In such machines where the seaming rolls or tools have been reciprocated toward the cans in predetermined successive or automatic reciprocations it has been necessary for the operator to be very accurate and expeditious in placing the cans with their caps thereon beneath the seaming tools and in removing the cans with their caps seamed thereon, and in case the cans were not applied and removed in proper timing and sequence there has been danger that the seaming tools would engage the cans or their caps in a wrong position with consequent damage to the cans and liability of injury to the operator.

An object of my invention is to provide means, in the class of machines referred to. to cause advance of the cap seaming tools toward the cans automatically only when a can is placed in proper position beneath the seaming tools; to cause automatic retreat of the seaming tools from the can after seaming, and to prevent further advance of the tools for seaming until a capped can has been removed and a new can placed in capping position. I provide means operated by the can when it is placed in proper capping position upon a support orbed beneath the reciprocative seaming tools to automatically start deviQQS t0 advance the seaming tools Serial No. 631,590.

toward the can and cause said tools to retreat and stop until the capped can has been re moved and another can placed in position to have its cap seamed thereon.

My invention is also adapted for use with tools other than for seaming cans, as will be referred to hereinafter.

My invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Similar numerals of reference indicate corresponding parts in the several views.

A. base or support 1, which may be supported upon a pedestal or in any other suitable way, carries an adjustable head 2 that supports capping devices or seaming tgpls, indicated generally at 3, located in position above the base or support 1 to operate upon caps a on cans A when in proper position upon said support. The head 2 is preferably adiustable tow ld 2 1d from Support 1 detail looking from the right to operate respecting cans or articles A of different lengths, for which purpose said head is shown provided with a threaded stem 4 that enters a column 5 on support 1, a suitable hand wheel 6 operative with said stem and column serving to adjust said stem and head 2 vertically, clamping means at 5" (Fig. 2) serving to retain the stem and head in set position. An arm or bracket 2 on head 2 is provided with a vertically disposed guiding bearing at 7 in which bearing a tube or sleeve 8 is adapted to slide, which sleeve is provided with a rack 9 exposed through a slot 10 in guide bearing 7, (Figs. 1, 6 and 7). A pinion 11 carried by shaft 12 journaled upon head 2 meshes with rack 9 and with a drive gear 13 journaled upon head 2, being secured to a shaft 14. I provide a spring to operate gear 13 to cause rack 9 and its sleeve 8 to rise, which spring may be arranged in any suitable way. In Fig. 7 I have illustrated a spring 15, preferably like a clock spring, shown within a barrel or drum 16 secured on arm 2, which spring is attached at one end to drum l6 and at the other end toshaft 12, which the spring surrounds. A sleeve 17 on said shaft is provided with a flange 17 having spaced holes or notches 17. A cover member 18 loosely mounted on sleeve 17 fits adjacent to the outer end of barrel 16 and is provided with an internal pin or projection 19 to fit either of the holes or notches 17. Cover member 18 has a projection 18 to engage a stop 16 on barrel or drum 16, and said member has a screw 20 to engage shaft 12 to retain the member in position, the shaft and sleeve 17 being rotative for adjustment within said member. A pin or bar 21 passes through sleeve 17 and shaft 12 to lock the sleeve to the shaft. The tension of the spring may be regulated by holding shaft 12, withdrawing screw 20, sliding the cover member 18 along the shaft to release pin 19 from a notch or hole 17" of flange 17 rotating the cover on the shaft the required amount, entering the pin 19 in a desired notch or hole 17*, restoring screw 20 against shaft 12, and allowing projection 18 to engage stop 16 to retain flange 17 with spring 15 under the desired tension. The parts described with relation to spring 15 are substantially similar to corresponding parts shown in Letters Patent granted to me October 10, 1922, No. 1,431,749. A handle or rod 22 projects from pin 21 and may be detachably retained by screw 23 (Fig. 7).

The handle may be used to rot-ate shaft 12 manually when it is desired to raise and lower sleeve 8 for any required purpose.

The sleeve 8 with the tools attached is to be raised and lowered with respect to can or article A by the operation of rack 9 and

gears

11, 13. In the example illustrated the seaming tool comprises a body 25 having a head or flange 26 provided with jaws at 2'? in which arms 28 are pivoted at 29 and are provided with suitable rollers 30 at their lower ends to engage the flange (1. of the can cap a, (Figs. 1417 The body 25 is slidably attached to a member 31 shown provided with stud screws 32 operative in slots 25 in member 31 for rotating the latter, (Fig. 6). Member 31 is detachably connected with a tubular spindle or shaft 33 that is rotative in sleeve 8, preferably by means of anti-frictionbearings at 34, 34 the bearing 34 sustaining spindle 33 on sleeve 8 and the bearing 34 resisting thrusts on the spindle. The sleeve and spindle are sustained and raised and lowered, by pinion 11. I have shown the lower end of the bore of spindle 33 provided with a tapering seat 33 receiving a correspondingly tapered portion 31 of member 31, said member being provided with screw threads at 31 to engage corresponding threads within the bore of spindle- 33, whereby the

parts

31 and 33 are secured together for rotation and may be detached. A controlling member is indicated at 35 shown having a cone-like portion 35 to co-operate with the arms 28, preferably having antifriction rolls 28, which member is preferably adjustably carried by member 31 by means of cooperating threads at 36. The spindle 33, at its reduced portion 33 above sleeve 8, (Fig. 6), is slidably connected with a gear 37 adapted to rotate said shaft, as by means of a spline and feather between said shaft and gear, through which gear the adj acent portion of the shaft may slide. The gear 3?.is in mesh with a pinion 38 on a shaft 39, which may be driven by any suitable means, such as by a belt, gearing or motor. In the construction illustrated the shaft 39 is the power shaft of an electric motor B, suitably secured upon. head 2, (Fig. 1). A head 40 is secured to a stem 41 as by screw 42, (Fig. 6), which stem is guidedin a plug or bushing 43 that is shown adjustably secured in the central bore of body 25 by means of screw threads 44, whereby said plug may be adjusted to be retained in set position by means of screw 43. The stem 41 is attached to a rod 45 which isfree within and guided by the bores of member 31 and spindle 33, which rod is shown projecting above 37. For convenience of connecting rod 45 to head 40 I have shown the lower end ofsaid rod located in a recess 41 in stem 41 and attached thereto by means of a pin 46, (Fig. 6). adapted to engage plug 43 to limit outward movement of head 40. i Lnti-friction bearings at 47 are shown provided upon the head 40, adapted to engage the lower end of plug 43, or a washer interposed therebetween, when the parts are in the seaming position. Springs 48 are provided to normally push head 40 away from body 25. Said springs Stem 4-1 has head 41 I are shown enclosed in tubular members 49 secured to and depending from the body 25, as from its head 26, within which members 49 plugs are slidable and provided with rollers 51 operable upon head 40, the springs 48 serving to normally press said rollers against said head to push the latter and rod 45 outwardly, (Fig. 6). Headed pins at 52 project from. body 25 in recesses in arms 23, and springs 54 in said recesses bear against the bottoms thereof and against the heads of pins 52, whereby said arms are normally pressed at their upper ends in the direction of controlling member 35 to normally spread their rolls 30 away from head 40. Rod 45 at its upper end above gear 37 is shown provided with a cross bar or yoke 55secured thereto by screw 56, and guide rods 57 depend from said bar or yoke and enterguiding bores .58 in posts or studs 58 secured on arm 2 on opposite sides of shaft 33 and rod 45, (Figs. 3, 6 and 6) Rod 45 thus is slidably supported but prevented from'rotating so that head 40 may be retained from rotating when operating in cap a of a can A. At such time the spindle or shaft 33, body 25 and parts connected therewith may rotate witlrrespect to the cap to cause the rolls 30 to engage the laterally extending flange a of the cap in cooperation with head 40 that engages the inner flange a of the cap,.(Figs. 14 and 16), to seam the flanges of the cap against the neck A of the can body. The inner flange a of the cap is on the inner side of the neck A against the neck and the outer flange (4 of the cap is on the outer side of the neck, whereby the flanges and neck are seamed together, (Figs. 15 and 17),. The bar or yoke 55 is adjustable along rod 45 by means of screw 56, and may be cap to prevent undesired pressure of said head againstthe cap.

lVhen the can A is placed upon support or base 1 in proper seaming. position beneath the seaming devices described, the can is stopped against. suitable guiding means,

indicated at 59 upon said support or base to position the can and its-cap properly with respect to the seaming tools. The guiding means 59 is shown in the form of a flanged member, (Fig. 1), adjustable by means of a slot 59 therein and screw 60 operative in said. slot and in support or'base 1, to accommodate cans: of different diameter. A trip member or lever is indicated at 61, pivotally supported upon column 5 at 62 upon a bracketfor arm 63 projecting from the column. 'Said trip device is shown in the form of a three-armed, lever the lower arm 61 being in position to be engaged by can A when on support 1 andthe. upper arm 61 65 to engage pin 64, (Fig. 1). The arm 61 is adjustable by means of threads 61 and retaining nut 61 to accommodate cans of different diameter. The upper end of rod 63 is provided with a notch 63 adapted to receive a pin or projection 66 carried by a rock arm 67. Said arm is shown forked at 67 to receive and guide the rod 63, (Figs. 3 and 9). The arm 67 is carried by 'shaft 68 j ournaled upon brackets or bearings upon head 2, said shaft being provided with an arm or projection 69 to control clutch means to be referred to. When a can is not upon base 1 the trip lever 61 will be substantially in. the position shown in dotted lines in Fig. 1, whereupon rod 63 Will be in a lowered position and

arms

67 and 69 will be depressed. When a can is placed upon support 1 and pushed against the guide 59 the can Will causetrip lever 61 to move to the cording to the diameter of cans or articles A to be operated on. Means are controlled by rod 63 and

arms

67, 69 for operating gear 13 to cause the tools to advance to the can or article A and to release the said gearing for the return of the tools from the can automatically. A sliding bar 70 is mounted in

bearings

71, 72 supported by head 2, (Fig. 1), which bar is provided with an arm or projection 73 adapted to operate an arm 74 carried by shaft 14, whereby when bar 70 is moved toward the right in Fig. 1 its arm 73 will operate arm 74 to rotate gear 13 anticlockwise, whereby pinion 11 will be rotated to cause the descent of spindle 33 and the .tools toward the cap on the can A below said operative position. Arm 74 is preferably provided with an anti-friction roller 74 to cooperate with arm 73. Arm 74 is shown pivotally attached to shaft 14, preferably being located in a recess 14 in an enlargement or head 14 on said shaft, and pivoted by means of a pin 14. A spring 14 cooperating with said head and with a plug 14 pushes the latter into a

recess

74 or 7 4" of arm 74 to normally retain arm 74 in set position, (Figs. 1 and 1 )Vhen it is desired to operate spindle 33 manually the arm 74 may be swungoutwardly to be retained by theplug 14 pressed by spring 14 into notch 7 i, said plug in notch 7a" normally retaining said arm in operative position, (Fig. 1).

A cam 75 secured 011 shaft 76 cooperates with bar 70 to operate the latter toward the right in Fig. 1 gradually, and when the steep edge 7 *.of said cam passes from said rodis shown provided with a loose gear 78 in mesh with a gear 79 secured on a shaft 80 journaled in bearings carried by head 2,

(Fig. 2), which shaft is shown provided with a worm wheel 81 in mesh With a worm 82 on shaft 39. By means of the gearing described the desired ratio of speed of shaft 76 with respect to the driven shaft 39 is obtained for correspondingly rotating cam 75.

The clutch means before referred to are provided to control intermittent rotations of shaft 76 and cam through the gearing described. A clutch member 83 is mounted loosely on shaft 76 and is secured to gear 78, (Figs. 2 and 4), as by means of screws passing from said gear into threaded holes 84 in clutch member 83, (Fig. 8). A collar 85 secured on shaft 76 adjacent to gear 78 retains the same in operative position, (Fig. 2). The clutch member 83 is shown provided with an extended flange 83 provided with spaced slots 83 to be engaged by the end portion 86 of a dog 86 that is pivotally supported on shaft 76 to rotate therewith, (Figs. 4, 5, 8 and 9). The dog 86 is shown pivotally carried upon a supporting member 87 that is secured to shaft 76, as by a pin 88, (Fig. 9), said member having spaced jaws 87 supporting pivot or pin 89 upon which the dog 86 is journaled. A spring 90 is secured at one end to member 87 and at the opposite end to dog 86, tending normally to tilt said dog in such a manner as to cause its end portion 86 to engage a notch 83 of clutch member 83, (Figs. 5 and 9). The dog is partly enclosed within the flange 83, and the portion of the dog outside of said flange is provided with a projection 83 adapted to be engaged by arm 69, (Fig. 5). When arm 69 is raised from projection 83, as in dotted lines in Fig. 5, the spring 90 will cause dog 86 to be tilted to engage its end 86* in a notch 83 of clutch member 83, whereby the latter through said dog will cause rotation of shaft 76, and when arm 69 moves into position to engage dog 86 the latter will be tilted to disengage member 83 and stop rotation of shaft 76 and cam 75, although member 83 will continue to rotate.

The operation of arm 69 is controlled by means of arm 67 and rod 63. An eccentric 91- on shaft 76 co-operates with rod 63 to disconnect it from pin 66 of arm 67 when the arm 69 is to oppose dog 86, as

in Fig. 5. When eccentric 91 is in position shown in Fig. 1, the notch, 63 of rod 63 will engage pin 66 of arm 67, so that when said rod is raised by the engagement of a can body with lever 61 the arm 69 will be moved from engagement with dog 86 to permit rotation of shaft 76, and during such rotation'the eccentric 91 will engage rod 63 and push it to the right in Fig. 1, to release pin 66 and arm 67 from said rod so that the arm 69 may descend into opposition to dog 86 to cause shaft 76 to stop upon making one complete rotation. When the can body is removed from support 1 the rod 63 will descend causing lever 61 to move outwardly and permitting re-engagement of pin 66 with notch 63 of said .rod. Such operations occur each time a can body is placed in position beneath the seaming tools. V

I preferably provide braking means to prevent the overrunning of shaft 76 and its cams. I have shown said shaft provided with a brake disk 92 enclosed by a brake spindle 33 with its tools will be raised, cams 1 7 5 and 91 will be in the position shown in Fig.

1, bar 63 and

arms

67, 69 will be-in the lower position, and lever 61 will'project into the path of can A, as indicated by dotted lines in said figure. A with its cap applied is placed upon support 1 and pushed to proper position beneath the tools, as against guiding stop or stops 59, the lever 61 will be moved to the position shown in full lines in Fig. 1, whereupon rod 63 will be raised to correspondingly raise

arms

67 and 69, and dog 86 will be released from arm 69. Spring 90 will cause said dog to engage clutch member 83 and thereupon shaft 76 will be rotated. Cam 75 will push bar 70 to the right in Fig. 1, thereby rotating arm 74 and gear 13, whereby spindle 33 and tools will be advanced to the can, said spindle and tools being continuously rotated by means of gear 37 and the driving devices therefor. During such rotation of shaft 76 the eccentric 91 will tilt rod 63 to the right in Fig. 1 and release arm 67 whereupon said arm and arm 69 will descend, the latter stopping in the path of dog 86. When the high part 75 of cam 75 passes from bar 70 the spring 15 will rotate gear 13 reversely to cause rising of spindle 33 and the tools When a can and the return of bar toward cam 75, the eccentric 91 correspondingly moving away from rod 63 to permit the latter to tilt toward pin 66. When dog 86 encounters arm 69, the dog will release clutch member 83 and shaft 76 will come to rest, having made one complete rotation. The capped can A will be removed from beneath the tools and thereupon rod 63 will descend causing pin 66 again to enter notch 63 of said rod and causing trip lever 61 to be moved to normal position in the path of a can to be placed upon support 1, the arm 69 remaining opposed to dog 86.

It will be understood that by the means described the advance of the spindle and tools toward and their retreat from the can A is'automatic, and that when the tools have onc risen from-the can they will not again descend until such can has been removed and another replaced, because

arms

67 and 69 remain depressed and arm 69' re 'tains dog 86 out of engagement with clutch member 83, it requiring lever 61 to be pushed back to cause rod 63 to rise to lift arm 69 from dog 86 before the spindle and tools will again advance to the work. Assurance is given the operator that when a can or article of work has once been placed in proper position on support 1 and the tools have operated on the cap upon the can or on such article and retreated that such tools will not again advance until lever 61 has been shifted forth and back, so that there will be no injury to the operator or the can or article, a further assurance being that the tools will not advance until the can or article is in the proper position to have caused the raising of arm 69 from do 86. a

. lily improved means for causing the automatic advance and retreat of spindle 33 toward and from the work to be performed may be utilized in connection with any other suitable tool or tools. In Figs. 12

and 13 I have illustrated a modified form of capping tools wherein the arms 28 move directly downwardly toward the flange a of cap a, the member 35 retaining the arms 28 in operating position and being adapted to adjust said arms for different gages of metal of the caps. Instead of the capping tools referred to any other corresponding tools may be used, such as set forth in Letters Patent granted to me, No. 1,266,519, May 14, 1918, and Nos. 1,370,039 and 1,370,040, March 1, 1921. Other tools also may be used for other than can capping purposes, such as drills, taps and the like, adapted to be attached to spindle 33 in any ordinary way, such as used in drill presses.

When it is desired to cause continuous rotation and reciprocation of spindle 33 and the tool connected therewith the trip member or lever, 61 1 and the rod 63 may be omitted, and the arm or projection 69 may be moved back out of the path of projection 86 of dog 86, so that said dog will not be actuated, whereby the corresponding clutch devices will remain in engagement and the motor will continuously operate spindle 33.
