Serial No. 588,386.

fllhis ,invention relates to inmrovementsl in machines forlning can ends with` a sealing compound, and; especially to a machine adaptedv interchangeably. to apply lining `*compound `to ianged can; ends of both circular i and` non-circular contour, like oval, square, rectangular or irregular shaped.

` One of theobsjectsof this `invention ils lthe provision of a machine for applying lining compound fto aican end flange, whatever the contour or shape ofztheendtmay be.`

` "Another object of ithe invention isthe provision ofa machine of this character, which `may be `readily converted from an arrangement `accurately lining a can end of one shape, into an arrangement for lining an end of "anientirely different shape.

Another ob]- ect of the invention istlie provision `of automatic means preventing the opening of'lthe compound nozzle, when a "cairendhas not been delivered to `receive the compoundwf y i .i .Y w

A further objectlof the invention is the `provision of a manualfcontrolV mechanism wherebyjthelopening Lofthe compound nozzle may Lbe prevented, whetherV there i was or was not a can-lend delivered.

1"With these obj ects in View the machine is `furnishedwith, a can endl magazine, where the can 'endsare piledy by hand Orotherwise ina stack, and `,an `automatic Vfeeding `device is provided foruremoving the lowermost can end in the stack, delivering it upon a lower chuck, mountedupoii Athe end of `a swinging arm. .Theflowercliuck, `supporting the can end, is then .elevated for a short distance, and brought into` engagement' with an upper chuck, "carried upon the end of another arm, clamping tliecan end between them.

`Rotarymotion Vfor one and one half revoe lutions then given the chuck and can end,

\ and `then .they .are brought to -a stop and lowered to the original elevation. y A nOzzlefada-pted to discharge sealing compound is stationarily secured above the chuck and furnishedwith a needle valve, adapted to beraised fromits seat and discharge seal-` ing compound into the `curled ,flange of the pan endpsooni after the chuck started `to rotate, and ithent-o be lowered upon its seat and stop the discharge of the compound, before the rotation of the chuck stops-` The needle valve keeps `thenozzle open `for somewhat more than one `complete revolution of the chuck. V

Means are provided to swing the chuck carrying arms towards and away from `the nozzle," during the rotation of theirregular shaped can end, `so as `to keep `the centerline of the curled iange under the discharge ztip of the nozzle. y

After thechuck has been lowered, theautomatic feeding device removes the lined can end from the chuck, delivering it upon a dis- Figure 5 isa `vertical cross section of the'v machine drawn to a larger scale, and taken 011 line 5-5 of Figure 2.

4form and size, corresponding with the form and size of the can ends, and of the guiding rods 4 secured to said base.

A recess 53 is cut on the lower face of the v base, as shown in figures 2 and 8, and within said recess are fitted to slide the can end feed slide 54, and the can end releasing bars 55.

vThe purpose of the can end feed slide 54 is to move a can end, released from the stack 5, vand place it upon a chuck 22; and to remove a can end from the chuck, and place it upon a discharge conveyor 91; whilev the purpose of the releasing bars 55 is to separate the lowermost can end from the rest of the stack, and drop it upon the surface of the table. i The feed slide 54 is adapted to slide upon the'surface of the table 2, being guided by the guides 92; it is driven by a crank 58, secured upon the vertical shaft 48, and connecting by means of a link 59 with a pin 60, carried by the slide 54.

The can end feed slide is made with two prongs 65 and 66` and is formed with the shoulders 93 and with the lugs 94, the former engage a can end, dropped upon the table by the releasing bars 55, and deposit it upon the chuck 22, while the latter engage a can end upon the chuck 22, and deposit it upon the conveyor 91.

The releasing bars 55 are placed next above the feed slide 54; they are two in number, and

are situated one on each side of the slide. They are formed with the upturned lugs 56 and 57 and are adapted to slide longitudinally, being guided in the recess 53.

The releasing bars are held normally by the springs 61 in the position at the extreme forward end of their travel, resting with the set screws 63, carried upon the lugs 57, in contact with the base plate 51, and are moved in the opposite direction against the action of the compression Y springs 61 yby the set screws 62, carried upon posts 64 near the ends of the prongs 65 and 66 of the feed slide 54, when said slide moves towards the can end stack, and return to the normal position at f the beginning of the forward stroke of the When the slide 54 is moving in a direction from the discharge conveyor towards the can end magazine, the releasing bars 55 remain at their normal position, and the can end stack is resting upon the lower supporting knife edges 98, the separating knife edges 97 being forwards of the stack; upon the approach of the slide 54 towards the stack 5, the releasing bars 55 move with the slide, the separating knife edges 97 entering .the stack next above the lowermost can end, leaving said can end rest upon thel `supporting knife edges 98, while the rest of the stack becomes supported by said separating knife edges 97 at a short distance before the end of travel of the releasing bars in the direction 'from the discharge conveyor towards the stack, the supporting knife edges 98 move out from beneathV the lowermost can end, letting it drop upon the surface of the table, to become engaged by the can end feed slide 54, upon its next forward stroke, and to be carried to the chuck 22.

Upon the forward stroke of the slide 54 the releasing bars follow the slide forwards, being driven by the springs 61. On the forward motion of the bars the supporting knife edges 98 enter beneath the stack, before the separating knife edges 97 move out from beneath it, letting the stack drop upon the supporting knife edges 98; in this manner the can ends are separated and removed one by one from the bottom of the stack and placed upon the chuck 22.

The chuck 22 is adapted to rotate in a horizontal plane, is capable to move for a short distance up and down, and has a swinging motion in a horizontal plane together with a bifurcated swinging lever, upon the end of which it is mounted. f

At one side of the machine there are secured the bearings 10 and 11, Within which a vertical tubular shaft 12 is mounted, the upper end of which extends for some distance above the upper bearing 10, where an arm 30 is keyed. Below the bearing 10 the tubular shaft 12, carries a bifurcated arm, co1n-A prising the long hub 16, and the upper and lower prongs 17 and 18. I

The bifurcated. arm is also keyed to the tubular shaft 12, being in alignment with the arm 30.

Bearings 19 and 20 are provided on the prongs 18 and 17, within which a spindle 21 is mounted; said spindle extending above the bearing 20, where the lowerv chuck 22 is keyed, and extending below the lower bearing 19, where a spur gear 23 for rotating the spindle 21 is secured; below the gear 23 a surface cam 24, having an outline corresponding to the shape and v'size of the cam end, is fastened.

For imparting a swinging motion around the center of the tubular shaft 12 to the bifurcated arm, a bracket 25 is secured to the frame of the machine, and avplate 26,

`plate73,"keeps the surface cam 24 in constant Contact, with said roller `28; the. rotation of `the cam 24 causing the swinging of the arm,

the?` tubular shaft 12 oscillating within the bearings a1-1d111.``

Thearm 30 is furnished with a bore 31, ari

l `ranged in vertical alignment With the spindle.

21-,`and within said bore a sliding sleeve34 is fitted; and* within said sleeve a tubular stem 33, carrying the upper chuck disc 32 y is mounted; athrust ball bearing 35, and an annular ball bearing 36 being interposed between said stem and said sleeve.

The sleeve 34 is provided with a flange 37,

fitting inside thebore 31 at thebottom, while a glandf `38 screwed into the upper part of the bore 31 guides the slgeeve at the top, and a helical spring 39 surrounds the sleeve, engaging at the top the gland 38, and pressing at the bottom against theflange 37, keeping the sleeve normally in aI downward position, the flange of a gland 69 which secures the outer race of the annular ball bearing 36 to the sleeve,`serving as a stop.` n The upper chuck 32'is thus held down yieldingly by theV helical spring 39, and rotates with little resistance.'`

The mechanism for raising and lowering the spindle 21 together with the lower chuck 221 consists of a forked lever 11() pivoted at 111 tothe hub 16 of the bifurcated lever, and engaging at thefree forked end a block 112,

` fitted upon the spindle 21, and heldin place bythe collars 113, anduof devices for actuating said forked lever; thesaid devices are a cam 114, secured upon themain driving shaft 40 of the machine, engaging a roller 115 carried upon the-end of one-arm of a bell crank lever 116, the other arm engaging a roller 117, carried upon the lower endvof a rod 118 connecting with said lever.

` The machine-is drivenfrom the main driving shaft 40, carrying the spur gear 42, which meshes `with an idler spur gear 43, revolving upon a pin 44, and transmitting motion to a spur gear 45, keyed to the driven shaft 41.`

The gear 42 Vof the driving shaft and the gear45 ofthe driven shaft are of the same diameter and pitch of teeth, and cause the a similar gear 89, carried upon the vertical drive shaft 50, transmits continuous` motion to said shaft.

" `The driving shaft 40, the driven shaft 41, the vertical can end feed-shaft 48, and the vertical drive shaft all revolve continu- V ously and at the same rate of speed, making one complete revolution, each` time a can end has been lined `with lining compound,

and the can end feedslide 54, driven by the vertical shaft 48, reciprocates also continuously, making a stroke forwards and back again, each time a can end is lined, the otherV devices in the machinev are so timed, as to conform to the motion of said slide.

For imparting an intermittent rotation to the spindle 21 of the lower `chuck 22 the following mechanism is used. t

The vertical can endl feed shaft 48 is mounted at the lowerend in a bearing 70, provided upon the cross plate 71 of the frame, and at theupperlend in a bearing 72, carried upon a cross plate 73 of the frame. i

A spider 74, provided with a long hub, is fitted to revolve freely around the shaft 48 and is: driven intermittingly from the short vertical shaft 50, by the devices herein described; the spider connects by a chain of gears with the spindle 21 of the chuck 22, causing its rotation, and it is desired that said rotation be uniform during the time lining compo-und is discharging into the curled iiange of the can` end, in order to distribute the compound more evenly; and it is also desired, that the starting and stopping of the rotation of the chuck be gradual in order to insure the smooth working of the machine.

The device here used fulfills the above stated requirements, it is of the nature of a Geneva cam, as it also transforms a continuousrotary motion ofone memberinto an.

intermittent motion of another, but differs in the nature of the motion produced. The rateof acceleration at thestarting'and of de-` celeration at stopping in this device is such as to take up a small part of the motion, leaving the middle portion of uniform speed,

while in the resultant motion of a Geneva cam, there is no middle portion of uniform speed, it is all accelerating, or decelerating.

y The spider 74 inl this case is formed with six arms, and its rotation for onesiXth part of a revolution at a` time is transmitted to the spindle 21 by means of the gear 75, securedf upon the hub of the spider 74, engaging a` pinion 76on a` vertical idler shaft 7 7 ,mounted 1n the bearings78 and 79 at the side of the frame ofthe machine, while a larger gear 8O,` secured upon theidlershaft 77, meshes with the gear 13, loosely mounted upon the tubular shaft 121,` imparting motion to it and to the gear 15, keyed upon the hub 14 of said gear 13; f

The gear 15 meshes with` an intermediate gear 81, which in turn engages the gear 23,;

keyedto thespindle 21, and causes its rotation. t

' The ratio of gearing between the spider gear and thegear'23 `of thespindle is i 13o such, asto `cause said spindle to vrevolve for one and one half of a revolution, each time the spider revolves for one sixth of a turn.

For transmitting intermittent motion to the spider 74 from the vertical shaft 50, there 5 are provided a plurality of antifriction rollers 82, mounted upon pins on the lower face of the spider, one on each arm, placed at equal distances from the center, and equally spaced one from the other; below. the spider is placed a disc 83, furnished with a hub 84, whereby it is keyed to the shaft 50, and upon said disc is secured a flat cam 85, having an outline of such a shape, as to enter between two adjacent rollers, and be 1n contact with both of them during the rotation of the spider, the constant contact prevents any back lash in the spider, giving it a smooth motion.

The ratio of the time the spider is in motion to the time it is at rest depends upon the distance between the shaft 48 and the shaft 50, and the rate of acceleration at starting, and deceleration at stopping, depends upon the curvature at the portion of the cam at both ends of its center line; the sharper the curves, the more rapid the acceleration.

Since said curvatures may be varied in different cams, the desired rate of acceleration of the spider may be obtained, by giving the proper curve to the cam.

In the machine illustrated, the spider 74 is moved for a distance of one sixth of a revolution, during the rotation of the driving shaft 50 through an angle of 110 and during the remaining 250, the spider is at rest in order to give time for the lowering of the lower chuck 22, for removing a can end from said chuck, for withdrawing a can end from the bottom of the stack and place it upon the chuck, and for lifting the lower chuck 22 and bring it in contact with the upper chuck disc 32, in order tov clamp the can end. j

In determining the distance required between the said shafts 48 and 50, it may happen, as in this case, that the center of the shaft 50 comes close to the path of travel of the roller 82. When the roller is in the position shown at 90 in Figure 4, the point of l contact of the cam surface with the roller being near the center of the shaft 50, said point of contact has little motion, and in order to move the roller with the required speed, it has to press upon the arm of the -spider in a direction too close to a radial line, thus subjecting the roller pin to an excessive strain; to avoid this strain, a roller 86 is mounted upon a pin 87, carried upon the cam 85, and cam surfaces 88 are formed l upon the arms of the spider. The roller 86,

the shaft 50, when the cam surface 85 acts upon them in a more favorable direction.

The cam illustrated gives an accelerating motion to the spider during 9 rotation of the same, then moves it for a distance of 42 at a uniform speed, and at last brings it to rest within 9 of motion.

It is evident, that this can not be accomplished by a Geneva movement.

rlhe rotation of the spider for a distance of 60 around the vertical shaft is transmitted to the spindle 21, causing it to make one and one half revolutions, the middle portion amounting to more than one complete revolution being of uniform motion, and the rest variable. l

Above the table, adjacent the can end magazine, is secured a nozzle 6, containing lining compound under pressure; the nozzle is held within the bore of a bracket 7, mounted upon the table.

The nozzle is furnished with a needle valve, provided with a stem 8, whereby it may be raised olf its seat in the tip 9 of the nozzle, causing a stream of compound to issue from the nozzle, and discharge into the curled flange of a can end, held in the rotating chuck below it, or it may be lowered, stopping the iiow of compound, after the chuck has turned for more than one revolution, and filled the curled flange of the can end all around.

Can ends are generally provid-ed with annular grooves and ridges for stiifening them, and the'lower chuck 22 is formed with an oval groove 67 and a ridge 68 accordingly.

lhen the spider 7 4 comes to rest, the chuck 22 also comes to rest, withthe major axes of the groove 67 and of the ridge 68 running in the same direction as the axes of the can ends in the stack, as shown in Figure 7.

The can end slide 54, which transfers the can ends from the magazine to the chuck 22, has the shoulders 93 so formed, as to maintain the` can end axes in the s ame direction, as they were in the can end magazine, insuring the registration of the grooves and ridges of the can ends with those of the chuck, when the former are placed upon the latter.

4.After the slide 54 has moved a short distance on its return stroke towards the magazine, the chuck is raised, and then rotated for one and one half revolutions, while the slide moves to the end of the return stroke, the lugs 94 passing beneath the chuck.

While the chuck 22 together with the spindle 2l and the cam 24 rotate, the latter, being held by the spring 29 against the stationary roller 28, causes the swinging of the bifurcated arm towards or away from the tip of the nozzle, to an extent required to preserve the alignment of the nozzle with the groove in the can end iiange.

After the chuck 22 has completed one and o ne half revolutions, the major axes of the chuck will again be in the same direction as proper position to receive another can end,

afterythe finished one has been removed by the lugs 94 of the slide 54.

The needle valve, controlling` the discharge of liningA compound into thefl-ange of the can end`,`,is operated by a. cam 99, carried upon the maindrivingshait 40, and safety devices are `interposed between said cam and the stem 8 of" the needle valve, to insure the opening'of the nozzle, when a can end to be lined is present upon the chuck 22, and to keep the nozzle closed, itthere is no can end upon the chuck to receive the compound.

For raisingfand lowering the needle valve there is rovided a beam lever 100, fulcrumed i at the middle upon a post 101, extending upupon the `main driving shaft 40, enaging a wards from an arm 102 of the bracket 7, said beam lever engaging at one end a collar 103, secured to the" stem 8V of the needle valve, andi` carrying atthe other end a rod 104,

furnished at the lower end with a sleeve 105 provided at itslower end with a tooth 1106, projecting-to oneside of it, and at its upper end with a handle 107, whereby it may be given a turn. A bearing 108, secured to the trame 1, serves to guide the end of the rod 104. The rod (is held in an upward position by a spring 109, placed upon the stem 8 of the needle valve, engaging at the lower end the collar 103, and resting at the top against theV guiding bracket 119, carried upon the bracket.

The rod 1104 is actuated by a cam 99, carried rol1er`120, mounted upon a pin carried upon one arm` of a bell crank lever 121, pivoted at 122, to a bracket 123, while a tension spring 1275, acting upon the other arm, tends to keep the roller in contact with the cam, oscillating the bell, crank lever.

A hook bar` 124 is pivotedto the bell crank lever, said hook barbeing adapted to swing towards the tooth 106, bringing the hook in alignment with said tooth, when a can end is presen-t upon `the chuck 22, or remain `at rest, the hook being out of alignment with thej tooth,` when there is no can end upon the chuck 22.

.The hook bar 124` engages the tooth 106V during the downward motion oi` the arm 121,

`and pullingV down upon the rod 104, causes' the liftingo the needle valve ott' its y seat, discharging lining` compound.

Foractuating the hook bar 124, a teeler rod 1261s made tof pass `through the `central opening 127' of the tubular stem 33, the lower endet said' rod extending downwardbeyond the chuck disc 32, while the upper end connects with a beam lever 128, fulcrumed upon a lug 129, provided upon the arm 30 and carryingV at the other end a rod 130, which passing through the inside of the tubular In the operation of the machine, a can end to be lined is placed upon the lower chuck 22 and the chuck is raised, until it engages the upper chuck disc 32;` the lower projecting end ot the teeler rod 126 then comes in contact with the center of the can end and is raised, rocking the beam lever 128, and lower` ing the rod 130 and the arm 131;` of the belli crank lever; the other arm 133 of the bell crank, connecting Vby means of the link 134 with the `hook bar 124, swings said hoo'kto# wards the sleeve 105, bringing it in alignment with the tooth 106, ready to pull upon it, when 4the arm 121 swings downward, and thus open the needlevalve.V y y In caseno can end has beenV placedupon the chuck 22, thefeeler rod`126 will not be raised by the upward motion of the chuck, the projecting end of the eeler rod entering the hole 135, provided in the lower chuck, andthe hook bar remaining out ofalignment with the tooth 106, as shown in Figure 6, will` `fail in its downward motion to pull the rod* "104 down and open the needle valve.

Then it is desired to set the machine by' hand, so as to prevent the opening of the needle valve controlling the discharge of lining compound, the tooth106 is turned toone side and out of alignment withthe hook bar 124 by means of the handle 107. The downward motion of the hook bar will not affect then the sleeve 105 and the rod 104, andthe needle valve will remain closed.

Forconverting the machine from an ar-V rangement lining can ends of one shape, into an arrangement for lining can ends of another shape, thecanend magazine together with the can end feed slide and releasinglba'rs, and the lower spindle 21 `together with the lower chuck 22 and cam 24 are replacedby others conforming with the shape ofthe can endsto-belined."" f

In transmitting rotary `motion from the stationary mounted shaft 77 to the movably mounted spindle 21, a number of intermediate gears wereused as shown in Figure 4.

When the arm carrying the spindle 21 swings towards or from the stationary roller, said swinging affects the rate of rotation ot the spindle; the swinging of the arm against a clockwisedirection tends toturn the gear' `81 againsta clockwise direction, turning theV gear23 and the chuck 1n a` clockwise direc-S the lining compound morefevenly,the`posi! tionof the tubular shaft in relation tethel position of the chuck, when its maJor axis is` in a direction across the machine, is so chosen, as to place the bifurcated arm in a direction at an angle with said or aXis of' the chuck, as shown in Figure 4.

The path of travel of the spindle 2l will be not along the center line of the machine, but at an incline with it, the component part of the motion in the direction across the machine moves the can end flange in relation to the stationary nozzle in the proper direction, and with substantially the proper amount to compensate for the disturbing effect of the swinging of the arm.
