CAN -SEAMING- MACHINE.

Specification of Letters Patent.

Application filed May 17, 1907.

Serial No. 374,200.

To all whom it may concern.

Be it known that I, HENRY DIEoKs, a citizen of the United States, residing at Eastport, in the county of Washington and State of Maine, have invented a new and useful Can-Scanning Machine, of which the following is a specification.

This invention relates to apparatus employed in the manufacture of cans, and has for its principal object to provide a novel means for securing the bottoms or covers to the bodies of cans by seaming.

A further object of the invention is to provide a machine in which successively operable seaming dies are brought into play during each operation, the preliminary or seaming dies first acting to make the initial turns or folds, and the flattening die or dies then acting to compress and flatten the seam in order to form a fluid proof joint, and these operations being carried on without stopping the machine until the seaming operation is complete.

A further object of the invention is to provide a machine of this type with means for controlling and adjusting the positions of the dies, so that the dies will be progressively advanced toward the work during the seaming operation.

1th these and other objects in view, as will more fully hereinafter ap ear, the invention consists in certain novel eatures of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the struc ture may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :Figure 1 is a side elevation, partly in section, of a can seaming machine constructed in accordance with the invention. Fig. 2 is a sectional plan view through the upper portion of the machine, parts being broken away in order to more clearly illustrate the construction. Fig. 3 is a vertical section through the upper portion of the machine. Fig. 4 is a transverse sectional view through one of the sets of die actuating mechanisms on the line 4-4 of Fig. 3. Fig. 5 is a detail section on the line 55 of Fig. 1. Fig. 6 is a detail pers ective view of the feed carriage detached. Eigs. 7 and 8 are detail views of the dies.

Fig. 9 is a sectional view illustrating a slight modification in the arrangement of the actuating mechanism. Fig. 10 is a detail view of a further modification.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

The frame of the machine comprises a suitable base plate 10 from which rises a standard 11 having at the top a horizontally disposed forwardly extending arm 12. The forwardly extending arm 12 is provided with openings for the reception of a vertically disposed spindle 15 which is stationary and which supports the dies, chuck and principal working parts of the machine.

Arranged in vertical alinement with the spindle 15 is a rod 16, at the upper end of which is secured a table 17 on which the can may be placed and elevated to position within the chuck where it is operated u on by the seaming dies. This rod has suita le guides formed in a forwardly extending bracket 18, and is operated from a cam 19 that is mounted on a stud 2O projecting from the standard 11, the cam acting through the medium of a bell crank lever 21, as shown in Fig. 1. The cam is actuated through the medium of worm gearing from a shaft 24 having bearings in the standard 11, the lower end of said shaft having a miter gear connection with a driving shaft 25 that carries suitable belt wheels.

Arranged under the chuck and the seaming dies is a bed or table 27 having vertically arranged parallel side flanges 28 between which the can body and can top or bottom are placed, the flanges serving to prevent lateral displacement as the work is moved to a position above the lifting table or bed. The side portions of the table 27 are provided with grooves 28 for the reception of a pair of bars 29 forming part of a work carriage, and one of the bars is pivotally connected to the upper end of lever 30, the lower end of said lever being fulcrumed at 31 on a stud carried by the bracket 18, and this lever carries an antifriction roller 32 that is engaged ,by the cam 33 on the stud or shaft 20.

The work carriage is provided with a pair of spaced work feeding arms 34 extending inward from the side bars 29, and adapted 'to engage with the can and can top placed on the table 27, and feed the same forward to a position over the lifting table 17. The cams are so arranged that after this feeding movement, the table will be elevated in order to direct the can parts into the chuck and'hold the same in position to be acted upon by the dies. After the feeding movement, the carriage returns to its initial position, it being noted that the arms 34 are spaced'from each other for a distance greater than the diameter'of the rod 16, so that the carriage may freely pass the rod, while the tableis holding the work in operative position.

The lower end of the spindle 15 is of comparatively small diameter, and carries a bevel gear 45 that is free to turn on the.

spindle. The teeth at thetop of this double bevel gear are engaged by a bevel pinion 48 on the forward end of a shaft 49 that has bearings in the arm 12 of the frame, and the rear end-of said shaft is connected by miter gears 50 to the vertically disposed shaft 24. This shaft 24 is likewise provided with a pinion 51 that intermeshes with a large gear 43. The gear wheel 43 forms a support for the several seaming dies, and in the present instance four dies are employed, two of these dies being advance dies for starting the seaming operation, and the other two being finishing dies for'completing the operation. The dies are arranged in diametrically opposed pairs, and provision ismade for moving them to and from operative position in successive order, and, also, for gradually feeding the dies forward as the seaming operation progresses.

De ending from the lower face of the gear whee 43 are four pairs of guides 53, the pairs of guides being spaced at ninety degrees from each other and each pair of guides is arranged to receive a slidable block 54 that is movable radially toward and from the center of the spindle 15. The lower portion of the block 54 is provided with laterally extended side flanges 56 thatv fit within a pair of grooves formed in a slide 58, and the inner faces of the lower wall of said slide 58 are grooved for the reception of the opposite sides of a die carrying slide 60 that is movable with the slide 58, and also has independent movement thereof.

The inner end of the slide 58 carries a stud 61 on which is mounted an anti-friction roller 62 arranged to travel inthe cam groove 41 for the purpose of causing the slides to follow the contour of the can. The lower slide- 60 is provided with a stud 63 carrying a die 64, said die being caused to travel in a path conforming to the contour of the can by the roller 62, and being gradually moved inward as the seaming operation progresses, this movement being independent of the movement of the roller.

The three members 54, 58 and 60 are connected together by a stud or bolt 66, on which is mounted a bell crank lever having two arms 67 and 68. The arm 67 is tapped for the reception of a screw 69 which engages with the slide 60, While the arm 68 is rounded, and is engaged by the enlarged head 71 of a vertically movable stud 72 mounted in the slide bar 54. Extending upward from the block 54 are spaced ears or lugs 75 which, also, pass through an opening 77 formed in the web of the large gear 43. These ears or lugs form bearings for a shaft 78 which carries a cam 79, the latter acting on an anti- -friction roller 80 that is mounted at the upper end of the stud 72. The cam is feathered to the shaft, so that the block 54, the ears 75 and the cam are free to move in a radial path toward and from the axis of the spindle 15. The inner end of the shaft passes through a bearing opening formed in a vertically extending rectangular web 81 that rises from the body portion of the bed 43, and to the extreme inner end of said shaft is secured a bevel pinion 82 that intermeshes with the lower set of teeth of the double bevel gear 45,

The construction of the parts is such that as the gear wheel 45 rotates, it will carry with it the members 54, 58 and 60, and these will follow the contour of the cam-groove 41-, while the bell crank lever, the stud 72 and cam 79 will be retained in constant vertical alinement with each other, the cam sliding on the shaft 78 and at all times rotating therewith as the bevel gear 82 is rotated.

In operation, the can parts are placed on the table 27, and are engaged by the carriage and moved rearward to a position over the small lifting table 17 which moves upward carrying with it the can and the can top or bottom to a position within the chuck, all of the dies at this time being withdrawn to inoperative position. During the rotation of the gear wheel 43, the advance dies will be moved inward as their cams 79 rotate, it being understood that the gear wheel 43 rotates from six to twelve times for the seaming of each can, and during about half the number of revolutions the advance dies are fed inward in order that the seam may be gradually formed. At the end of about half the number of revolutions, the working ends of the cams pass beyond the studs 72 ofthe advance seaming dies, and the latter are re.- tracted. The finishing dies are then moved up by their cams 79 and are constantly fed forward by said cams. until the seamingoperation is complete, and at the completion of the operation, the active faces of the cams pass beyond the actuating studs of the dies and allow the latter to move under centrifugal action to inoperative position, so that the can body, properly seamed, is allowed to descend with the table. The finished can is allowed to rest on the table 27 and is forced out of the way as another can is fed to the machine.

Instead of arranging the cam 79 to slide on its shaft, the cam may be fixed to the shaft and the shaft feathered to the gear 82, as shown in Fig. 9, or in some cases the shaft may be keyed to both the gear and to the cam in which case the block 54 may be held rigidly to the gear 43, and the lever arm 68 will be provided with a roller 90 to engage a plate 71 as shown in Fig. 10, or the construction may be otherwise modified for the purpose of securing a gradual forward feed of the seaming dies in addition to the mechanism for maintaining the dies in proper posi tion with respect to the contour of the can body.

The cam groove 41 may be made of any desired shape in accordance with the character of cans to be made, and the block 40 may be detachable in order that blocks having cam grooves of diflerent contour or different dimensions may be substituted in case cans of different shape or size are to be made.
