MACHINE FOR ASSEMBLING METAL RECEPTACLES.

Application filed December 6, 1913.

To all whom it may c0ncern Be it known that I, HANS F. RICHTER, a citizen of the United States, residing at- Winston-Salem, in the county of Forsyth and State of'North Carolina, have invented new and useful Improvements in Machines for Assembling Metal Receptacles, of which the following is a specification.

This invention relates to a machine for assembling metal receptacles such as cans, boxes and the like and the covers therefor, particularly covers that are hinged to the cans drjooxes, and has for its object to provide improvements in machines of a type in the operation of which receptacles and their covers each with a hinge member thereon, are fed along separate channels and afterward brought together to be delivered later to mechanism forming a part of the machine that engages the hinge member on the re-. ceptacle with the hinge member on the cover, and to a die punch that clenches the hinge members of the receptacle and cover securely together. The receptacle with its cover hinged thereon then passes from the die punch, the cover, being closed over the receptacle as it progresses by suitable devices, upon a table, rack, or other support and there collected in an orderly row ready for removal. This machine may be operated alone or in connection with a machine for forming beads on the open ends of the receptacle, a single driving shaft being common to both machines. ceptacles are delivered from the heading machine directly into the feeding channel of the clenching machine, the covers are fed by hand or otherwise into the cover channel.

In the accompanying drawings showing one embodiment of the invention :Figure 1 is a front elevation of the complete machine. Fig. 2 is an elevation from the receiving or feeding end. Fig. 3 is a plan view looking in the direction of the arrow 3, Fig. 2. Fig. 4 is a fragmentary detail view showing the receptacle feeding device.

Fig. 5 is a view of the cover feed and cover hopper into which the covers are delivered, viewed in the direction of the arrow 5, Fig. 2. Fig. 6 is a transverse sectional View on the line 66, of Fig. 3. Fig. 7 is a similar view on the line 7--7. Fig. 8 is a sectional view on the line 88. Fig. 9 is a view similar to Fig. 8, with the parts in a slightly Specification of Letters Patent.

different position. Fig. 10 is an enlarged sectional view of the upper part of a receptacle, its cover and a fragment of the machine in position to have the hinge clenched. Fig.11 is a view similar to Fig. 10, including the clenching punch in the act of completing the fastening of the hinge. Fig. 12 is a cross sectional view on the line 1212 of Fig. 3, showing how the cover after the hinge connection is finished, is partly closed over the receptacle. Fig. 13 is a like sectional view on the line 1313 showing the means for fully closing the cover over the receptacle. Fig. 14 is a perspective view of one form of cover as it is fed into the machine. Fig. 15 is a similar view of the upper end of a receptacle adapted to receive the cover shown.

In the drawings, 20 indicates a bed plate upon which is supported the frame work and operative parts of the machine. Bolted on top of the bed plate at or near the center thereof are two upright standards 21 parallel to each other and spaced apart for a vertically movable ram or plunger 22 fitted in guides on said standards and reciprocated by a crank 23 on a shaft 24 turning in bearings also on the standards. A pitman 25 extends from the crank 23 to the ram 22 for reciprocating the same. A. die punch 26 with a suitably shaped lower end is fastened on the bottom of the ram to clench the hinge connections between the receptaclesin the form of cans and their covers.

From. the left of the machine, as seen in Figs. 1 and 3, extends a horizontal trough or guide 27 along which cans or boxes A,

(this being the form of receptacle illustrated in the drawings), travel to the clenching die. This trough or guide is made in the present instance of two angle plates 28, 29, rigidly fastened by suitable connections, to maintain them correctly spaced, and transversely inclined, the rear angle plate 28 being higher than the front angle plate 29 as shown, to maintain the cans at a proper angle to engage the covers. At the bottom of the trough or guide 27 in the center thereof is a longitudinally reciprocating bar-30 on which are pivoted a number of fingers 31 spaced apart, that are held by springs 31 perpendicular to the cans when the bar is moved toward the machine Patented Apr. 20, 11915.

1 of the bar.

Supported upon the bed plate 20 in front of the ram and forming a continuation of the trough or guide 27 is a channel plate 32 inclined upwardly at its rear similar to the trough and grooved in its longitudinal center for a reciprocating slide bar 33 from "one end of which a lug 34 depends for moving'said bar. A link 35 is connected to the lug and to the" free end of an arm 36 "on a"rock shaft 37 from which shaft projects ase'cond arm 38 vibrated by a connecting rod 39 pivoted at one end thereto, andat its fothe'r end to,a crank pin 40 onthe driving shaft 24. Extending transversely across the slide bar 33 are a number of cross pieces 41, shorter than said cams and spaced apart a distance slightly greater than their width, on the ends of'which cross pieces are pivoted fingers 42, that operate m'a similar way to the fingers 31, and are maintainedperpendicular to the cans each by a spring 43 "holding a finger against a stop pin The pair of fingers 42 on each cross iece 41 receive'the cans A from the troug orguide 27 and carry themby an intermittent movement through the machine past the cover hopper 45 where during a pause the 'covers B are placed in position over the mouths of the cans, then to the punbh 26"wliere again pausing the hinges connecting the covers and cans are clenched,

- tin ite extent transversely of their directionthen past a closing means, to be described later, for closing the covers over the cans and finally to a cltute 46 where the covered cans are ejected from the machine.

' Above the trough 27 and the channel plate 32 are a series of friction bars. 47 that press upon the cans and hold them in engagement with the fingers 31, 42 permitsaid cans, however, to slide to a limof movement through the machine to receive their covers and interengage the hinge members. The under faces of the friction bars 47 are preferably covered with felt 48 .or some other material that will maintain .the cans in any position to which they may be moved. The friction plates are carried onarms 49 hinged on the front side-of the trough or guide 27 and the slide plate or 965$ 50 t e can 5 Rio and fingers in the hopper.

trough 27 and channel 32 should such be necessary.

Behind the rear plate 28 of the trough or guide 27 and parallel therewith is a strip or bar 53 that with said plate 28 forms a horizontal duct 54 along which the covers B are brought to the hopper 45. The bottom of this duct is formed by an endless belt 55 passing around a driving roller 56 near said hopper and a guide roller 57 at the outer end of the guide trough 27. A second shorter belt '58 supported on rollers 59, 60 runs abovethe belt 55 at its inner end and spaced therefrom sufliciently far to grasp the front and rear sides of the covers B and deliver them directly into the hopper 45, see Fig. 5. On the shafts of the belt rollers 56, 59, are driving pulleys 61, 62, respectively, around which a belt 63 passes that runs over a pulley 64 on the main shaft 24 and is guided by idle pulleys ,65 on one of the standards 21.

The machine herein illustrated is designed to secure upon cans A that have hinge members, preferably pintles a properly fastened thereon, as in Fig. 15, covers B formed with open hinge members in the form of hooks 5, see Fig. 14, that stand substantially vertical with a slight rearward inclination when the covers are in the hopper, Fig. 7.

The hopper 45' is supported on the rear side of the channel plate 32 a short distance within its recelving end, and is inclined backwardly a short distance from a vertical position, as clearly shown in Fig.7,

lower cover rests on the bottom of the hopper 45, one of its ends being held a ainst a wall 66 by a spring actuated finger 6 that yields to permit the cover to pass out of the Over the hopper is a horizontal lever 101, one end fulcrumed' at 102 and having a pin 103 projecting rearwardly from its other end. Between its ends is pivoted a finger 104 that extends downwardly into the hopper 45. At each descent of. the ram 22 the pin 103 is struck thereby, which swings the lever 101 downwardly and causes the finger 104 to press upon the covers B in the hopper and force them downward should they get caught or otherwise fail to drop by gravity to the bottom of the hopper. On the return of the ram, a spring 105 raises the lever 101 and the finger 104. At the completion of each forward reciprocation of the slide bar 33, the mouth of a can mamas A will be brought in exact alinement with the lower cover B in the hopper 45, its bottom resting over a push plate 68 fixed on the end of a slide 69 movable in a seat .in the channel plate 32 and held retracted by a spring 70. The push plate is advanced to push the mouth of the can within the cover by an arm 71, pivoted to the slide 69, fixed on one end of a shaft 72 extending through the channel plate and provided with a lever 73 on its other end, the free end of said lever, which may have a friction roller thereon, being moved by a cam lug 74 on the under side of the slide bar 33 during the retraction of said bar. The mouth of the can is first pushed into the cover by the push plate 69 sufficiently far to carry the pintle a beyond the ends of the hooks b which latter support the mouth of the can, as in Fig. 8, its base, the only other point of support resting on the channel plate 32, the can being held on these two points of support by the friction bar 47. Upon the next forward movement of the slide bar 33, the fingers 42 thereon carry both can and cover beneath the ram 22, the die punch 26 thereon being immediately over the hinge members. During this movement, the bottom of the can passes ofi' the push plate 68 and onto a spring actuated plate 75 that is substantially in line with the push plate 68 when in its advanced position and is held by said plate within the cover. The hinge hooks b are here supported on their under sides by a die block or anvil 76, Fig. 11, in the u per surface of which is a shallow groove 7 7 to assist the punch 26 in the formation of the hinge. During the descent of the ram and before the die punch 26 encounters the hooks b, the can is ushed downward and out of the cover su ciently far to permit the hinge members thereon to interengage by the following mechanism: A plate 78, Fig. 2, bolted on the ram and having a cam groove 79 therein actuates through said cam groove a lever 80, Fig. 8, pivoted on the channel plate 32 and having a slot 81 therein through which passes the cross bar of a yoke shaped frame 82, the legs 83 of which slide in bearings in a bracket 84, Fig. 9, grooved on one side at 85 to form a holder'to receive the cover B. The ends of the legs 83 engage the upper edge or mouth of the can A and push the same downwardly against the spring pressed plate 75 until the openings a" between the pintle a and the rear side of the can are above and in line with the ends of the hooks b on the cover, whereupon the can, because of the downward presthe openingsa' see Fig. 10. .The die punch 26 grooved .at 86 on its under side then presses upon the hooks b, that, owing to the shape of the groove, are bent over the pintle a roller 90 that completely closes the cover.

a, as in Fig. 11, to complete the hinge connection. The next forward movement of the slide. bar 33 carries the can and its cover from beneath the ram and brings another thereunder. The bottom of the can leaving the ram passes from the pressure plate 75 against one side 87 of the channel plate 32, while the top of the can and cover are sup ported on a bar 88, a continuation of the die block 76. Upon this bar is a cam surface 89, that pressing upon the cover, partly closes the same over the can, as in 'Fig. 12. From here, on the next movement of the can, the cover B is brought in contact with over the can. This roller is yieldingly supported on one end of a lever 91 fulcrumed at 92 to the channel plate .2, and has a spring 93 connected to its other end sufficiently strong to hold the roller 90 against the can 1 cover and close it, but which will yield and permit the can to pass, if for some unexpected cause the cover is prevented from closing, and thereby avoid injury either to can or its cover. After passing the roller 90, the can escapes the friction bars 47 and comes in contact with an upwardly inclined plate 94 that raises the forward side of the can sufiiciently to give it a quarter turn whence it falls upon the inclined chute 46; down which it runs in front of a push plate 95 onto an inclined gathering rack or table 96 where the completed cans are lined up for packing. The push plate 95 is advanced to forward the cans on the rack 96 at each operation of the machine by an arm 98 on the rock shaft 37 pivoted to a slide bar 97 below the channel plate 32, from which slide bar an arm 99 projects forwardand is fastened to a stem 100, on the push plate.

In operation, the main shaft 24 rotates continuously to raise and lower the ram, drive the cover feeding belts 55, 58, and, through the connecting rod 39 and connections, reciprocate the receptacle feed bar 33. Covers B are placed with their rear sides, upon which are the hinge members I), on the belt 55 and carried by said belt and its companion belt 58 into the hopper 45. Receptacles, in the present instance fiat cans or boxes with two opposite sides rounded and open at one end with a pintle a on one flat side .ofthe open end, are placed with the side containing the pintle downward, in the trough orgulde 27 and intermittently fed by the fingers 31, 42 on the respective feed bars 30, 33 past the hopper 45, theram 22 and the cover closing devices into the chute 46. The cans or boxes are held in engagement with the feeding fingers and .inany position into which they may be moved by the friction bars 47 At the end of each forward movement of the feed bar 33, the canssto while the feed bar returns to reengage ,e cans. At eacli pause in the travel" of the cans one of them stops opposite the hopper 45 in line with the lower cover B therein. With each return of the feed bar, the cam block 74 thereon actuates the arm 71 and slide plate 68, against which the bottom of the can is resting, and pushes said can in a direction transverse to the line of feed to cause its mouth to enter the cover B in the hopper. This movement of the can carries the hinge member or pintle a thereon beyond the hinge member I) on the cover so that the rear side of the can is supported just below the pintle, upon the ends of the hooklike hinge member 5. The next forward movement of the feed bar 33 carries the can and its cover, which is partly on the can, beneath the ram where there is another pause While the feed bar returns. During this pause of the can, the ram with its die punch 26 and cam plate 78 descend, the cam plate first swinging the lever 80 to slide the yoke frame 82, the legs 83 of which engage the mouth of the can and push it a short distance out of its cover against the spring actuated plate 75, the movement being only sufficient to register the spaces a between the pintle a and the side of the box, with the hook ends of the hinge member I) on the cover. Immediately the hinge members a and b are interengaged by the downward pressure of the friction bar 47 above the can, the ends of the hinge member projecting nearly vertical with a slight rearward inclination toward the cover, see Fig. 10. The can at this time is supported at its bottom on the channel late 32 and at its top on the die block 6 with the hinge members in the shallow groove 77 of said block, its longitudinal axis lying at an angle to the horizontal with the mouth end higher than the bottom. The cover is also in an inclined position and supported in the groove 85 in bracket 84, the axis of the cover cor-' responding to the longitudinal axis of the can being inclined in the opposite direction and forming an obtuse angle therewith greater than one hundred and eightydegrees. The opening thus left between the can and the cover affords sufficient room for the die punch 26 to enter and clench the hinge members. The groove 86 in the bottom of the die punch encounters the ends of the hinge member 5 near the end of the downward stroke of the ram and by its shape, curls said member over the pintle a in the manner indicated in Fig. 11. The ram now rises and the can and cover are carried from below the same by the feed from beneath the friction bar 47 and against an inclined plate 94, its side upon striking this inclined plate is raised and the can caused to make a quarter turn before sliding down the chute 46 on one of its narrow sides to an inclined tray or table in front of the push plate 95 that moves the newly completed can against the previously deposited ones and advances all on the tray a short distance.
