HUGH M. ROSS, OF WOODHAVEN, NEW YORK, ASSIGNOR TO ADRIANCE-MACHINE y WORKS, INC., OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK.

SEAMING MACHINE.

Application led October 27, 1921. Serial No. 510,711.

T o all lwhom it may concern:

Be it known that l, HUGH M. Ross, a citizen of the United States, residing at Woodhaven, in the county of Queens and State of New York, have invented new and useful Improvements in Seaming Machines, of which the following is a specification.

My invention relates to searning machines and more particularly to machines for affixing the heads to the bodies of cans, this invention being an improvement upon the apparatus disclosed in United States Patent No. 810,245 to Benjamin Adriance and Amos Caleson.

ln the machine shown in the said patent, the rotation of the head carrying the tools or operation performing members is started and stopped for each seam. Under this condition, the brake band for the rotating head, especially after considerable use, does not invariably stop the comparatively heavy mechanism sufficiently quickly, and. as a result the body of the head and the cam ring which operates the tools sometimes overrun their 25 proper relative positions before the rotation of the head stops, whereby the tools are forced inwardly by the cams so as to prevent the insertion of the can or other article to be operated upon between the tools. Furtherlnore the starting and stopping of the mechanism takes considerable time and causes objectionable wear on the clutch controlling the starting and stopping of the machine.`

An object of my invent-ion is to obviate the above defects. With this end in view, the rot-ation of the major portion of the moving mechanism in the preferred form of my 1nv vention is continuous, only the relative Inovement between the cam member or other actuating member and the rest of the head being started and stopped for each seam.

Other objects, features and advantages of my invention will appear more fully 1n the 15 following detailed description and appended claims. In order that my invention may be more clearly understood, attention is hereby directed to the accompanying drawings forming a part of this specification, 1n which- F ig. 1 is a side elevation of a machine containing one embodiment of my invention;

Fig. 2 is a front eleva-tion of the same;

Fig. 3 is a top plan view of the same;

Fig. 4 is a horizontal section taken on line e5 4-4 of Fig. 2; Fig. 5 is acentral vertical'sectional view of the upper portion of the machine;

Fig. 6 is a horizontal section taken on line 6-6 of Fig. 5;

Fig. 7 is a horizontal section taken on line 7-7 of Fig. 5; and

Fig. 8 is a sectional view of details of construction. l ,A n Referring to the drawings,`in a pedestal 1 is Journaled a horizontal driving shaft 2 whlch carries at its inner end two beveled gears 3 and 4, its outer end carrying' a pulley 5 whereby power is taken intothe machine and the machine driven when the clutch 6 1s thrown into operative position by its controlling lever 7 (Fig. 5). The clutch may be of any suitable type and itis thought to be unnecessary to describe the same in detail. The gear 3 is keyed to the shaft 2 so as to rotate therewith but the gear 4 is free to rotate with respect to the shaftunless connected thereto by a clutch 8 (Fig. 5). This clutch, as shown, includes a movable clutch member .splined to the shaft and having secured thereto a facing 9 of hardened steel or other wear resisting material, the clut-ch facing 9 being arranged to co-act with the clutch member l() of similar material threaded upon the hub of gear 4.

The following mechanism is employed for moving the clutch'member 8: A T-shaped lever 11 pivoted, as at 12, to the pedestal hasvconnected to its arm 13 a fork 14 projectin into an annular recess in member 8. T e opposite arm 15 of the lever llfis connected toa spring 16 which tends tomdye the lever so as to throw the movable clutchy member 8 out of mesh or operative relation with the clutch member 10 on the gear 95 4. For moving the lever 11 against the action of spring 16, a link 17 is connected adjacent one end to the arm 18 of the said lever, the opposite end of the link being ecnnected through a link 19 with a pedal or controlling member 20. As shown, the adjacent ends of the

links

17 and 19 are connected for a purpose hereinafter described to a rock arm 21. As shown, the upper end of the link 17 is connected to the arm 18 of the lever 11 by a spring connection 22, whereby the clutch 8 may be readily thrown into operation without jar.

After the clutch member 8 has been thrown-into operative position by depression of the pedal 20, it 1s held in that position until the seaming operation on the cam is complete. To this end, the arm 13 of lever 11 is connected to a horizontal slide 24, the@ forward end of which is provided with a laterally projecting detent portion 25 (Fig. 6) which has a rear shoulder 26 (Fig. 6) arranged to be engaged by the pin 27 at the upper end of lever 28 when the clutch member 8 is in operative position. The lever 28 is pivoted as shown at 29 for movement about a horizontal axis. A spring 30 tends to hold the lever 28 in operative or latching position.

Referring mpre particularly to Fig. 5, the forwardly projecting arm 30 at the top of the pedestal has secured thereto, as by screws 31, a post 32 formed with a flange 33 at the lower end thereof. A disk or head 34 surrounds the post 32 and is supported on the ange 33 for rotation coaxially with respect to the said post. Fixed to the disk 34, as by screws 35 is a beveled gear 36 which meshes with the beveled gear 3. To the lower end of the post 32 is secured, as by bolt 37, a block 38 which serves both as the chuck portion of the mechanism to hold the can and head assembled while being operated upon and as a uide for certain parts hereinafter referre to. i

At spaced points around theY disk or hea 34 are arranged sets of devices for controlling the positioning of the operation performing members and tools. ll have shown three tools and actuating means therefor but it is understood that the number of tools is immaterial. Except for the tools per se, the devices referred to are` identical, and ll shall accordingly describev only one of these devices.

Referring to Figs. 6,7 and 8, a lever 40 is fulcrumed in the disk, its fulcrum Jbeing supported by a boss 41 formed thereon and which carries a. nut 42 for holding the lever in place. The free end of this lever carries a roller 44 adapted to run in the cam groove 45 at the under face of the block 38. This groove is made to conform to the: outlines of the can so that when the disk or head 34 rotates the roller follows a path coinciding with the outline of the can. As shown, the

outline is rectangular, the cam groove being co-axial with the head or disk 34. The lever 40 has pivoted thereto and intermediate its ends, as, at 46, another lever 47. The

inner end of the lever 47 carries a tool 48l which as shown is in the form of a narrow roller. The other end of the lever 47 carries a pin 481 which bears against the lower arm f 49 of a lever which has a vertical pivot portion 50 extending through the head 34 and at the upper end of which are lever arms 51 and 52. yThe arm 51 carries a rotatable folrecense lower 53 which is arrangedto coact with a cam 54. Tn order to permit adjustment of' the osition of the tool with respect to the wor the pin 48, as shown, is made adjustable so that the relative positions of the levers 47 and 49 may be variedl as required,

" the pin being threaded into the lever 47.

The various levers are held in proper re lationship with the followers 53 in engagement with the cam by means of the spring or yielding bearing arranged between the

levers

40 and 47 intermediate the p-ivot 46 and the inner ends of the levers. This bearing comprises, as shown,a pin 55 projecting downwardly from the lever 40 and engaging with a spring pressed pin 56 carried by lever 47. (See Fig. l8).

Fach of the levers 47, as stated, carries a Suitable tool. Where' three of these tools are used, as shown, the first may be employed to effect a preliminary turning down of the projecting flange on a can cover, such asl shown in Fig. 11 of the aforesaid Patentk 810,245, the second to perform an intermediate shaping of the edge as shown in Fig. 12 of said patent, and the third to finish the seam as shown in Fig. 13 of the said patent. The tools per se are preferably arranged under the rollers 44 and take, together with the levers 47 carrying the same, their general direction of movement from the movement of the lever 40; but the actuation of the tools, whereby they .are caused to change*I the shape of the metal is imparted thereto by the action of the cams 54 on the levers coacting therewith, whereby the toollevers A 47 are shifted by the lever arms 49,

Considering the, cam more in detail, the head or disk 34 has a ring 60 mounted thereon for rotation rio-axially with the said disk or head. This ring is provided, asshown,

with three cams 54 arranged at different elevations, each of these cams coacting with one ofthe followers 53. This ring is also provided with a beveled gear 62 meshing with the gear 4. Tt is thought unnecessary to go into detail as to the shapes of these cams but it may be stated generally that each of the cams is provided with a pocket portion 548, which permits the tools to be held a suicient-distance away from the axis of the apparatus to permit the ready positioning of the can or other article to be operated kupon between t-he tools, it being understood that at the'beginning and end of the formation of a 4seam on-a can all of the followers' 53 'occupy "the recessed portions 54El `of corresponding cams. The remainder of the cams are formed so as to bring the tools successively into operation and to prevent the arms 52 from moving.

To effect the release of the latch 28, the. l

levers 52 are provided with upstanding proill@ ini

the movable parts connected thereto rotate f path of projection 64 (see Fig. 2) of the latch lever 28 to release the latter when the followers 53 move into the recessed portionsL 54a of the cams at the end of the seaming operation.

The can or other article to be operated upon is adapted to be supported upon a table 65 carried by a shaft 66 which is vertically movable in bearings in the pedestal 1. This shaft is prevented from rotating by means of an arm 67 which is secured to the shaft and has a sliding non-rotating engagement with the pedestal. F or elevating the table so as to force the can against the chuck, the arm 2l is secured to and is adapted to' rotate about its axis, a cam member 68 which coacts with a roller 69 on a sleeve 70 slidable on a shaft 66 and carrying a spring 71 by which shaft 66 and table 65 are supported by reason of the engagement of the sprin with the under surface of the member 67,. It will be seen that by the depression of the pedal 20 not only is the clutch member 8 thrown into Aoperative position but the table 65 is also elevated into operative position. By reason of the spring 71 the arresting of the movement of the table 65 need not arrest the movement of the clutch member 8 into operative position and gears may be so pitched that the disk or" head 34 is rotated six times while the ring 6() is rotated five times.

When the machine is at rest the tools are, as stated, in their outermost position, the cam followers 53 being located in the recesses 54a of the cams. The machine is started by shifting lever 7 to throw the clutch 6 into operation whereupon the head 34 and continuously. The clutch member 8 being in its unclutched or inoperative position, the gear 4 is free to be rotated with respect to shaft 2 by the gear 62, the ring 60 being rotated simultaneously with the head 34 by reason of the coaction of the followers 53 with the recesses 54a.

A can or other varticle to be operated upon having been placed upon the table 65, the pedal 20 is depressed whereupon the clutch member 8 is thrown into operative position causing the power to be transmitted from the driving shaft to the ring and the table is elevated to bring the head of the can against thestationary chuck on member 38. At the same time the slide 24 is moved forwardly, the latch pin 27 engaging behind the shoulder 26 to hold the clutch member 8 and 'the tabley in operative position.` 'Ivhe head 34 and cam ring 6() are now being rotated with respect toeach other so that the cams 54 act u'pon the cam followers 53 to desired seam. At the end of one rotation of the head 34- with respect to the cam ring 60, the cam followers 53 will drop into the resesses 54a, thepin 63 being outwardly suiiiciently far to enable the'one which is nearest the extension 64 on the latch lever 28 to trip or release Vthe said lever, whereupon through spring 16 the latch 24 and the clutch member 8 are moved into inoperative position and the table 65 lowered. iThe head 34 of the machine and the 'parts carried thereby and driving the same continue to rotate but there is no longer any relative movement between the cams 54 and their followers 53; so that after removal of the can which has been operated upon and placing a new one upon the table upon the depression ofI the pedal, the only rotation which need be imparted to the mechanism at the top of the machine is a slight rotation between the disk 34 and its operating means on the one hand, and the ring 60 and its operating means on the other hand. As a result, there is little wear upon the machine in operatiomand it can be operated with considerable speed.
