- The'general arrangementof the ymachine to 'w'hi'clrthe invention ⁇ is inthe'present case applied is as follows:
- . 1'() is ainainshaft havinga suitable clutch I llandfabrale 12 both of which are acf tuate'd by lever 13V pivoted atllll'end so ar-A Y ranged 'that when' theclitch is thrown in'tl'e Hh v bevel gears/15 and 16 the former ⁇ driving bevel gear 17 of the pedestal drive and the latter meshing with bevel gear 18 driving upright shaft 19.
- said upright shaft is provided with a bevel gear 2O that meshes with a bevel gear 21.0n shaft 22 which latter carries a 'bevel gear 23 meshing with bevel gear 24 on shaft 25 carrying head 2.
- Shaft 19 also carries a worm 26 meshing ⁇ with worm gear 27 on cam shaft 28.
- each of said-shafts being mounted as follows: Carried by the framework is a guide 29 having slots 30. 31 is a slide adjustable in said guide and secured in position by means of a bolt 32 extending through slot 30. The slide carries trunnions 33 supporting a bearing 34 for shaft 7. Carried by the framework is another guide 35, for each seaming tool shaft, in which guide is mounted a slide 36, said slide being confined by a gib 37. Suitably secured to slide 36 is a box 38 having trunnions 39 supporting a bearing 40 for shaft 7.
- Slide 36 is moved back and forth from rockshaft 41 byL means of suitable connections as 42 to thereby impart an in-and-out movement to shaft 7, said shaft pivoting around upper trunnions 33 and also moving about lower trunnions 89, the extent of the rocking movement being limited by surfaces 43. 44 and 45 are stop surfaces limiting the movement of slide 36.
- Box 38 is adjustable on slide 36 by means of threaded member 46 freely rotatable in extension 47 of slide 36 and in threaded en-V gagement with box 38.
- a gear 48 At the upper end of shaft 7 is a gear 48 in constant mesh with gear 49 on shaft 25 and at the-lower end of shaft 7 is a gear 8 moving in and out of mesh with gear 9 also on shaft 25.
- gears 48 and 49 are for the purpose of maintaining gears 8 and 9 in such relative position that they can be thrown in and out of mesh; and it will be further understood that the previously described adjustments of shafts 7 are used only when it is desired to substitute gears of different diameters as when changing from one size of can to another.
- rlhe pneumatically-operated actuating device is as follows 50 and 51 indicate two cylinders carried by the framework one for each seaming tool. Sliding in each cylinder is a piston 52 having a connecting rod 53 connected to rock-shaft 41 by knuckle 54 and rod 55.' Suitable valve means are provided here taking the following form: 56
- valve rod having a reduced portion 57 and a head 58.
- This valve rod slides in a passage 59 to which leads air inlet pipe 60 and from which there 1s an exhaust opening 61.
- 62 is a passage leading from cylinder 50 ⁇ (or 51 as the case may be) to Vpassage 59.
- t will be understood that if valve rod is raised the exhaust opening 61 will be covered by a portion of said rod and head 58 will be elevated so as t0 establish communication between air inlet 60 and the cylinder, and that, conversely, if valve rod is lowered, into the position indicated in full lines in Fig. 7, communication between the airinlet and the cylinder will be prevented and communication between the cylinder and exhaust opening 61 will be established.
- the pneumatic device is thus a single acting device and a spring 63 is used to move the piston in the other direction. constructed the pneumatically-operated device acts to move the seaming tool toward the work and the spring to retract it from the work. It may be said here that the stroke of the piston should preferably be so adjusted with the stroke of shaft 7 that the seaming tool completes its inward movement against the work without slide 36 coming into contact with stop 44.
- Vmeans a very quick and powerful blow is imparted by the seaming tool, said blow being at the same time cushioned to some extent by compressibility of the air or other fluid used.

the work is not eiected until near theend,
of the seaniing operation.
This long-continued engagement of the seeming tool with thejinetal of the cover and bot y tends to change, adversely, the characteristics 'of the metal.. Fuitherniore7 especially when acting on non-circular Vbodies and covers, in certain types of -seaining Inachi es it is customary to so arrange the parts that during the time the vsearnifig'tool is moving toward the work certain gears are moving into in'esh, the gears .re'herredVA to ibe. v'the ones that drive they seaniing tool.

Suitable work. holding means Such as pedestal l and head 2nite providedfbetween which'a Acan 3 with its cover 4 'is placed. 5 and `6 indicate two lseaming too-ls, 5 being the first Ioperationtool and `6 the finishing tool.. Each of these tools has a certain stroke moving it toward and away fronrthe work, by suit-able actuating means to be presently described, so yarranged that each tool lcompletes its stroke toward the work substantially at the beginning of'its seaming opera-tion. `@ne revolution of the 'work will therefore complete the seaining open' ation of `one tool.
In thefpresent vcase each seaming tool is carried byfa seam-ing tool Ashaft TInovably mounted andliaving ati-ts lower lend 'a' gear Sthat'is'mo'vecl intoand out cit-mesh with `near 9 moving with head 2. lnasrnuoh as the 'tool completes its inward "stroke substantially at the beginning Iofits sealning operation one vofthe vrgears 8 *andgear 9 are brought fully intomesh substantially at'the beginnin'gof :theseaming operation of av too.
Any suitable a'ctujzfitingz-rneans'fsuchA as a erably a pneulnatically-oper-atedv device'is utilized bn taccount of the quickness offits inotionanda'lsobecause of the yielding char'-v The'general arrangementof the ymachine to 'w'hi'clrthe invention `is inthe'present case applied is as follows:
. 1'() is ainainshaft havinga suitable clutch I llandfabrale 12 both of which are acf tuate'd by lever 13V pivoted atllll'end so ar-A Y ranged 'that when' theclitch is thrown in'tl'e Hh v bevel gears/15 and 16 the former `driving bevel gear 17 of the pedestal drive and the latter meshing with bevel gear 18 driving upright shaft 19. At its upper end said upright shaft is provided with a bevel gear 2O that meshes with a bevel gear 21.0n shaft 22 which latter carries a 'bevel gear 23 meshing with bevel gear 24 on shaft 25 carrying head 2. Shaft 19 also carries a worm 26 meshing` with worm gear 27 on cam shaft 28.
7 indicates a seaming tool shaft, there being two such shafts in the present instance, each of said-shafts being mounted as follows: Carried by the framework is a guide 29 having slots 30. 31 is a slide adjustable in said guide and secured in position by means of a bolt 32 extending through slot 30. The slide carries trunnions 33 supporting a bearing 34 for shaft 7. Carried by the framework is another guide 35, for each seaming tool shaft, in which guide is mounted a slide 36, said slide being confined by a gib 37. Suitably secured to slide 36 is a box 38 having trunnions 39 supporting a bearing 40 for shaft 7. Slide 36 is moved back and forth from rockshaft 41 byL means of suitable connections as 42 to thereby impart an in-and-out movement to shaft 7, said shaft pivoting around upper trunnions 33 and also moving about lower trunnions 89, the extent of the rocking movement being limited by surfaces 43. 44 and 45 are stop surfaces limiting the movement of slide 36. Box 38 is adjustable on slide 36 by means of threaded member 46 freely rotatable in extension 47 of slide 36 and in threaded en-V gagement with box 38. At the upper end of shaft 7 is a gear 48 in constant mesh with gear 49 on shaft 25 and at the-lower end of shaft 7 is a gear 8 moving in and out of mesh with gear 9 also on shaft 25. It will 'be understood that gears 48 and 49 are for the purpose of maintaining gears 8 and 9 in such relative position that they can be thrown in and out of mesh; and it will be further understood that the previously described adjustments of shafts 7 are used only when it is desired to substitute gears of different diameters as when changing from one size of can to another.
rlhe pneumatically-operated actuating device is as follows 50 and 51 indicate two cylinders carried by the framework one for each seaming tool. Sliding in each cylinder is a piston 52 having a connecting rod 53 connected to rock-shaft 41 by knuckle 54 and rod 55.' Suitable valve means are provided here taking the following form: 56
indicates a valve rod having a reduced portion 57 and a head 58. This valve rod slides in a passage 59 to which leads air inlet pipe 60 and from which there 1s an exhaust opening 61. 62 is a passage leading from cylinder 50` (or 51 as the case may be) to Vpassage 59. t will be understood that if valve rod is raised the exhaust opening 61 will be covered by a portion of said rod and head 58 will be elevated so as t0 establish communication between air inlet 60 and the cylinder, and that, conversely, if valve rod is lowered, into the position indicated in full lines in Fig. 7, communication between the airinlet and the cylinder will be prevented and communication between the cylinder and exhaust opening 61 will be established. The pneumatic device is thus a single acting device and a spring 63 is used to move the piston in the other direction. constructed the pneumatically-operated device acts to move the seaming tool toward the work and the spring to retract it from the work. It may be said here that the stroke of the piston should preferably be so adjusted with the stroke of shaft 7 that the seaming tool completes its inward movement against the work without slide 36 coming into contact with stop 44. By these Vmeans a very quick and powerful blow is imparted by the seaming tool, said blow being at the same time cushioned to some extent by compressibility of the air or other fluid used.
The valve rods 56 are automatically controlled by suitable means which in the present instance are as follows: 'It will be understood that the two seaming tools do not act concurrently but one after the other.
Therefore when the air is acting to advance one tool the other should be retracted. 64 and 65 indicate two cams on shaft 28. 66 and 67 indicate two rockshafts carrying bell cranks 68 and 69, the former connected Vby link 7 O to valve rod of cylinder 50 and theA latter connected by link 71 to valve rod of cylinder 51. The bell ycranks carry cam rolls 72 and 73 that engage 'with cams 64 and 65 and these cams are so related circumferentially on shaft 2 8 that they act successively so that when one valve is open the other is closed. Springs as 74 may be used to force the cam rolls to follow the contour of the cams. 75 is a'detent cam also mounted on shaft 28 and 76 is a pivot-ed detent or latch having roll 77 engaging with the detent cam. Detent cam 7 5v has two recesses 78 as shown and the timing, in the present instance is such that the work makes about three revolutions to a one-half revolution 'ofy shaft 28. and 65 is also provided with two'active cam surfaces as shown. Provision is preferably made whereby the latch is retracted from the detent cam and whereby at the saine time the brake is released and the clutch is thrown in. When this happens therefore the parts begin rotation, the valve ofthecylinder of the first operation roll is opened to admit air for about one revolution of the work after which the valve is closed and the exhaust opened; then the valve of the cylinder of the finishing rollV is opened to admit air for about one revolution of Vthe As here nok Each ofthe cams 64 work after which the exhaustisY opened, Thus the seaming tools actv successively.k After the seamingy cycle is completed` cam 7,5 has brought its other recessadj'akcent roll 7 7, and simultaneously with this the clutch is withdrawn and' the brake` applied thus stopping the operation. v Provision is also preferably made whereby the same control mechanisnithat actuates v the latch, brake and clutch also seryes to lift and` lower the pedestal andAV as here shownk these parts talrethey following, form Bevel gea-nifl' isf loosely mounted'on pedestal shaft 79.v and said. shaft isvertically movable,k in bearingl 80..
