Specification of Letters Patent.

application tiled July 11, 1916. Serial No. 108,594.

To all whom it may concern .1

Be it known that l, Axnr. doHNsoN, a citizen of the United States, residing at Ualrland, in the county of Alameda and State of California, have invented certain new and usefuhlinprovements in Apparatus for Eeaming Ends to C21I1-B0dl8$, of which the following is a' specification.

the present invention relates to canning machinery, and more particularly to a machine for sealing cans used for the preservation of food and other products by what is known in the art as the double seaming process.

in this process, the adjacent flanges of the can body and end are interfolded, by means of suitably formed pressure rolls, to malre a tight seam; and to accomplish this, either the can and its end must be rotated while in engagement with the seaming rolls, or else said rolls must be carried by a rotating head, which revolvesabout the can end. 'l he latter method is objectionable on account of the unavoidable weight of such a seaming head, which must not only carry the rolls in their orbit about the can end, but must also permit them to be rnoved into and out of engagement therewith. I

lln the machines already linow'n in the art, making use of the first mentioned method, the can is rotated by a rapidly rotating chuclr which descends into frictional contact with the end of the can positioned thereunder, or against which the can is elevated. lln either case, the effect is the same, via-- that the rapidly rotating chuck is brought into contact with the hitherto stationary can end. Under such circumstances, the inertia of the can body, particularly when filled with relatively heavy material, causes a momentary slip between the can. end and the can body. This slip is apt tomutilate the fragile ring liner interposed between the adjacent flanges of the body and the end, and will most certainly do so if said liner be moist. inasmuch as the liner is very liable to be moist, either from spilling, if the contents of the can contain a liquid, or from the steam used in the cooker, the per ccntage of lealry seams arising from this cause is relatively high.

The object of the present invention is to provide a machine for the described purpose in which, first, the danger of mutilating the ring liner is eliminated; second, the cans are continuously ladvanced throu h the mach1ne; and thlrd, the weight 0 the moving parts, especially those which operate at ,rela-' tively high speed, is kept within reasonable limits.

This object is carried out, in a 'eneral way, by feeding the cans successively onto a contmuously revolving table; clamping the can andits end by a temporarily nonrotating chuck which descends upon said end; imparting rotation to said. chuck and the can and end held thereby, and bringing the seaming mechanism in operative relation with the flange of said can; and finally releasing the seamed can from the chuclr and removing it from the machine.

In order to comprehend the invention reference should be had to the accoinpany mg. drawings, wherein-- Figure l is a perspective view of the machine.

Fig. 2 is a central vertical section.

Fig. 3 is a horizontal section taken on the line 8-45 of Fig. 2 and viewed in the direction of the arrows.

Fig. 4 is a broken horizontal section, enlarged, taken in four different planes repre sented in part by the line l 4.- of Fig. 9, and viewed in the direction of the arrows.

Fig. 5 is a detailed vertical section of one ofthe can chuck spindles, taken in the direction of the arrows on the line 6-6 of Fig. 4.

Fig. 6 is similar to Fig. with the trunnion yclres and cam followers added, show ing the can clamped by the chuck.

Fig. 7 is a broken horizontal section taken in the direction of the arrows on the line 7-7 of Fig. 6.

Fig. 8 is a vertical sectional view on line VIII-Vlll of Fig. 7.

Fig. 9 is a similar view with the seaming rolls and seaming roll arms removed.

Fig. 10 is an elevation of one of the seam-- ing roll arms and seaming rolls, removed.

In the drawings, the reference numeral l. designates a suitably constructed base, from which rises a fired central column 2, Fig. 2 of the drawings, said column supporting, at its upper end, a gear case or housing 3.. it drive shaft 4 carrying at its outer end a belt pulley 5 is suitably journaled in said housing 8, and carries on its inner end a bevel gear 6, adapted to mesh with and drive a second bevel gear 7. fired upon the upper end of a central vertical shaft 8 extending t ll till

through and having bearings within the column 2. The lower end of said vertical shaft 8 carries a gear 9. which meshes with a pinion or gear 10 fixed to a short vertically disposed counter-shaft 11 carried in suitable journal brackets 11 within the base 1. The upper end of said counter-shaft also carries a fixed pinion 12. i

A turret 13, carrying mechanism to be described hereinafter, surrounds the column 2 below the gear housing 3, and is supported by and fixed to the upper end of a rotatable sleeve 14 whose lower end portion is threaded to receive a nut 15. Said nut 15 is formed with a flange 15, which lies within a gear ring 16, the latter being fastened to the flanged hub 17 of a rotatable table 17 by means of bolts 16. Said table 17 is keyed for vertical sliding movement, upon the sleeve 14, as at 17", and has an annular bearing, here shown as V-shaped. in a flange 18 at the upper portion of the base 1. A set screw 19, passed through the hub 17 of the table 17 and bearing against the nut 15 locks said nut 15 securely to said table 17 and the fixed gear ring 16. so that all of said parts rotate as a whole with the sleeve 14. the latter carrying, as before stated, the turret 13. The gear ring 16 meshes with the pinion 12 on the counter-shaft 11, and is rotated thereby.

When it is desired to change the position of the turret 13 vertically with respect to the table 17, to enable the machine to operate on cans of different sizes. the set screw 19 is loosened, and the nut 15 turned upon the sleeve 14, and within the gear ring 16. to raise or lower said sleeve with respect to said nut. F or this purpose a removable shaft 20 is provided, the same having a crank handle 21 upon 'its outer end and bevel pinion teeth 22 upon its inner end. Said shaft is inserted through a journal 23 in the base 1, so that its toothed portion 22 engages a series of corresponding teeth 24 1 formed in the lower face of the nut 15.

Thus by means of the exterior crank 21, the nut 15 may be turned upon the threaded sleeve 14, when the locking screw 19 is loose. to raise or lower said sleeve and the turret 13 with respect to the table 17. It is understood that the adjusting shaft 20 is withdrawn when the machine is in normal operation.

Within the gear housing 3 is a bevel gear 27, meshing with the bevel gear 6 on the drive shaft 4. Said gear 27 is fixed upon a downwardly extending sleeve 28. surrounding the upper portion of the column 2. and rotatable thereon. A ball thrust bearing 29 is provided at the lower end of said sleeve 28. A spur gear 30 is keyed upon said sleeve 28 within the turret 13-. and moves up and down thereon when the position of said turret is vertically adjusted. Said gear 30 meshes with a series or" pinions 31, Figs. 2, l. 5. and 6 of the drawings, each provided with a hub 31' having a bearing in the top plate 13 of the turret 13. Each of said pinions 31 is associated with a can chuck mechanism. of which four are shown in the drawings, although it is to be understood that any convenient or desirable number may be used. All of said can chuck mechanisms are identical in construction. so that a description of one will suilice for all.

-1 vertically disposed spindle 32. Figs. 4;, 5 and 6 of the drawings, has its upper end extended within the hub 31' of each pinion 31. and is freely rotatable therein. Said upper portion of the spindle 32 is provided with a plurality of longitudinally disposed grooves 33. shown in the drawings as tour in number. said grooves receiving balls 3-1 positioned within segmental clutch blocks 35 lying within the pinion 31. A spring ring 36. surrounding said clutch blocks. normally retains the same out of engagement with the interior of the pinion 31. but. as will be readily understood from Figs. 5 and 6 of the drawings. an upward movement oi the spindle 32 causes the balls 31 to ride up on the shallow lower ends 33 of the grooves 33, and by so doing to expand the clutch blocks 35 into engagement with the interior if the pinion 35. The rotation of said pin on 35 is thereupon transmitted to said spindle 32. by means of the clutch blocks 35, the balls 34. and the grooves 33. Thus the spindle 32. when in its lower position. is idle. but when raised to its upper position. Fig. 6 of the drawings. rotates with the continuously rotating pinion 31.

For the purpose of thus moving the spinile 32 lineally, up and down. a hall bearing thrust trunnion 37 is provided upon said shaft. whose outer. or stationary portion 37 1s pivotally connected at 38 with a lever 38. said lever being fulcrumed at 40 upon a suitable bracket 39 carried by the turret 13. and having at its inner end a cam following roller -11 adapted to lie within and follow a cam groove 42 formed in the peripheral surface of a stationary cam memher 13 fixed upon the central column 2.

durrounding the lower end portion of the shaft 32 is a sleeve 44, forming the upper portion or a chuck spindle 44. carrying on its lower end a can end chuck 45. Said sleeve is keyed to the spindle 32, as shown it -16. so that the two are forced to rotate together. although said sleeve is freely slidible on said shaft. Said spindle is jouraaled for rotary and lineal movement at 17 in the bottom plate 13" of the turret 13. .1 trunnion 48. Fig. 5 of the drawings. similar to the trunnion 37. is mounted upon the upper end portion of the sleeve 4-1. and has its outer member 1-8' pivotall v coir aected, at 1-9. with a lever 1-9, said lever till being fulcrumed at upon the bracket 39,

Fig. 6 ft e drawings, and carrying upon its inner? end a cam following roller 51 adapted to follow a groove 52 formed in the stationary cam member 43 below the groove 42, Fig. 2 of the drawings. Thus the spindle 44, carrying the chuck 45, rotates with the shaft 32, and is raised and lowered,

fiber, is inserted in the outer wall of the chuck spindle journal 47, and has slight horizontal movement therein, so that its inner end can be forced into contact with the chuck spindle a l, by means to be hereinafter described, to check the rotation of said spindle.

AL seamin head shaft 54, Figs, 5 and 6 of thedrawings, is journaled for oscillatory rotation in the lower end plate 13 of the turret 13, adjacent to the chuck spindle 4:4. Said seaming head shaft is rovided at its upper end with a lever 55, carrying at its end a cam following roller 56 adapted to lie within and follow a cam groove 57 formed in the lower end face of the stationary cam member 43, said mechanism providing the means for oscillating said seaming head shaft.

The lower end of the seeming head shaft 5d, which terminates in an enlargement 5 1-,

*' carries a seaming head, comprising an end plate 66, held to the enlargement 5d of the shaft 54tby the screw bolts 58' and above the said end plate 56 is mounted a dish 59, secured to said shaft 5d, and provided with peripheral teeth 59, Fig. 7 of the drawings. The enlargement 5 f and the end plate 58 are so constructed as to provide when the parts are in assembled relation a dove-tailed groove or channel-as. A pair of seaming roll arms 60, carrying seaming rolls 61 and 62, journaled upon pins 63, for the first and second seaming operations respectively, are adjustably carried by the scanning head shaft 54: being pivoted thereto above the toothed disk 59, and within said arms are worms 6t, having exterior heads 64" adapted to receive a wrench, and having engagement with the teeth 59" of said disk 59, so that by the manipulation of said worms, the arms ,60 may be adjusted about the disk 59 and the shaft 54:. Each'searning roll arm 60 is provided with a bifurcated inwardly projecting tongueextension 60' which, when the arms are in assembled position, fits and works within the dovetailed groove or channel a, and-within the bifurcated portion of the said dovetailed tongues 60 fits the toothed dish 59.

ft. recess '65 is formed in the upper surface of the dish 59,1Figs. 5, 6 and 7 of the draw-- igs. i, 6 and 7,

rings, to receive a radially disposed plate 66,

whose inner end loosely surrounds the shaft 54, and whose outer portion carries, on its under side, a gear segment 67, Figs. 5, 6 and 7 of the drawings. A tongue 68 extends beyond the end of said plate 66, and freely engages a vertically disposed slot 69 in the sleeve 14, thus preventing said plate 66 from oscillating with the seaming head. Within the end plate 58 is a transversely disposed rotatable spindle 70, having at one end a gear portion 71 adapted to mesh with the gear segment 67 on the stationary plate 66,

whereby said spindle is rotated through a part of a revolution, when it is bodily moved by the oscillation of the seaming head. The other end of said spindle carries a freely rotatable tucking roll 7 2, eccentrically mounted insaid spindle 70, as shown at 73. Thus it will be seen that the tucking roll 72 is moved upand down by the partial oscillatory rotation of the spindle l0, asthe seaming" head is oscillated by its shalt 54 Mounted preferably within a seat or socket 17 in the table l'l-in vertical alinement with each can end chuclt a5, is a freely rotatable can supporting plate 74, Figs. 5,

6 and 7 of the drawings, each of which can supporting plates rotates on a vertical axis and is preferably supported upon ball-bean ings 7 5, and has its upper surface flush with the surface of said table 'l'l. The can; 76 whose end 7'7 has been loosely applied, is placed upon said rotatable plate 7d by means to be described hereinafter, and is correctly located thereon by a guide pocket 76, Figs. 3, 5 and 6 of the drawings. The end chuck 45, which is now stationary, is" then moved downward, by the continued rotation of the turret l3, acting through the agency of the cam groove 52, the lever t9, and the trunnion 48, until it firmly engages the can end .77, thus securely clamping the can 76 with its end f'l between the supportingplate ft and said chuclr d5, Figs. 5 and 6, illustrate respectively the positions of said chuclr d5 before and after making" said downward,

movement.

After the can 76 has been thus clamped by the hitherto non-rotating chuclr 4 5, the turret l6 continues to revolve, and cam groove 42 actuates the lever 36 to lift the spindle 32 to connect the same, by means of the clutch bloclrs 35, with the continuously rotating pinion 31, as shown in Fig. 6 of the drawings. flotation is thus imparted to the spindle 62, thespindle i l, the chuck 4,5,and the can 76 held thereby. fit the same timethe seaming head shaft 54 is rocked by means of the cam groove 5?, which movement first raises the tuclting; roll l2 into engagement with the flange of the can end, then brings the first operation seaming roll 61 into engagement with said flange,

and finally moves said tucking roll and said ltlll lllti first seaming roll out of engagement, and brings the second operation seaming roll 62 into engagement to complete the seamed flange. By this time the rotation of the turret 13 and the table 17 have carried the can from the position A to the position B, Fig. 3 of the drawings, when it is released by the chuck 45 and removed from the table by a deflector plate 80.

By providing for both the reciprocation and the rotation of the upper chucks the mechanism for those purposes is much simplified, and bettter located for the construction and operation of the machine, to attain with certainty the desired results that no relative rotation shall at any time take place between the can body and cover, which would have the injurious effects above mentioned.

Cans are fed into the machine from a feed table 81, Figs. 1, 2 and 3 of the drawings, whose surface is preferably level with that of the'talole 17. The feed mechanism. which will now be described. is driven from the pinion 12 on the vertical counter shaft 11, through an idler gear 82. which meshes with a gear 84 secured upon a vertical shaft 85,. Said vertical shaft 85 also carries a bevel gear 86, Fig. 2 of the drawings, which meshes with a similar gear 87. Fig. 3, fixed upon a horizontal feed shaft 88. This horizontal shaft carries a pair of sprockets 89. which drive feed chains 90. Idler sprockets 91 support the outer ends of said chains so that their upper runs operate in grooves 92in the surface of the feed table 81. The upper runs of said chains. it is understood. move toward the shaft 88.

A third sprocket 93 is fixed upon the shaft 88 for the purpose of driving a timed feed chain 94 provided with regularly spaced can engaging lugs or flights 95. Said chain runs over an idler sprocket 96. and its upper run moves toward the drive shaft 88 in a groove 97 in the feed table 81. A pair of spaced swinging guide arms 98 and 99, pivotally connected to the feed table 81 at 98 and 99 respectively, and spaced apart by an adjustable inverted U-shaped tie rod 100, are positioned to engage the cans coming in on the feed chains and guide the same laterally onto the timed feed chain 94. The guide arm 99 has a lateral extension 101, to which is connected a rod 102 carrying on its end a piston 103 working within a dash-pot cylinder 10 1. A spring 105 surrounding said rod 102 normally holds the guide arms 98 and 99 in the position shown in Fig. 3 of the drawings, but when a can, advancing between said arms, strikes against the side of one of the flights of the timed feed chain 94-, said arms give sufiiciently to permit the flight to pass the can. after which said can is moved into place in front of the succeeding fiight by the return movement of said arms. The dash-pot 101- prevents said return movement from taking place too suddenly.

The cans are transferred from the timed feed chain 94: to the table 17 by the following mechanism :The vertical feed shaft 85, Figs. 2 and 3 of the drawings, has fixed thereto a disk 106, above the feed table 81. Said disk 106 carries two oppositely disposed radially projecting fingers 107, said fingers being pivotally connected with said disk at 107'. so that they are capable of swinging movement in the plane of their revolution about the center of said disk. Each finger 107 carries a cam follower 108, adapted to rlde in a cam groove 109 formed in the under surface of a fixed cam member 110, held .11 superposed relation above the disk 100 oy a bracket 111 fixed to the feed table at 112.

The action of said cam causes the fingers 107 to run ahead of the rotary movement of the disk 106 to advance the can rapidly from the timed feed chain 91 onto one of the can supporting plates 74 of the rotating, table 17. and then subsequently to lag sufficiently to disengage said can and allow the same to be carried off by said table 17. The can is guided in this transfer by a guide plate 113 and by the surface 114- of the guide plate 80.

A flexible spring member 115, Figs. 1 and 3 of the drawings, carried by a bracket 110 rigidly secured to the guide plate 80 by a stud 117, lies in the path of the fiber braking plugs 53 carried by the chuck spindle journals 47. so that said plugs are pressed inwardly against said spindles when riding over said spring member 115. The chuck spindles and the chucks are thereby brought to rest after having been released from the continuously rotating pinions 31, and the can ends 77. at the position B, Fig. 3. as hereinbefore explained, and before said chucks arrive at the position A, to descend upon the succeeding can end.

Thus the principal objects of the invention are achieved. The cans are carried through the machine continuously by continuously operating mechanism: a temporarily rotatively stationary chuck descends upon the can end and clamps the can and its end securely; rotation is then imparted to the can and its end, through said chuck. and the seaming rolls brought into operative position; and finally the can is released from the chuck and carried out of the machine, and the rotation of the chuck is stopped in preparation for its engagement with the next can end. The entire operation of the machine is automatic and the working parts thereof brought into action in timed relation for the work to be accomplished.

It will be noted that a can to be seamed 1s first positioned on a suitable freely rot-.1-

lllllll table support, that while so positioned its end is clamped thereto by a vertically movable can chuck prior to the sean'ling rolls acting against the flange of the can end, that means are then brought into action for imparting rotation to the can chuclr tor rapidly revolving the clamped can on its ()Wll axis, and the seaming rolls brought into action for seaming the can end to the can during the rotary movement thereof. in the drawings the apparatus is illustrated as a multispindle machine, but it is obvious that such is merely the preferred embodiment of the invention, due to the increased Capacity gained thereby.

l am aware that many changes may be made in the form and construction or the device as herein described andillustrated, without in any Way allecting the principles ot the invention, it being understood that the form herein described and illustrated is merely that whioh is preferred for reasons of practice. l, therefore, do not wish to limit myself in this regard, but, on the contrary. l wish to be construed as claiming the invention as broadly as the art will permit.
