CAN-HEADING MACHINE.

Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed April 10, 1905. Serial No. 254,778.

To all whom it may concern:

Be it known that I, CHARLES W. GRAHAM, residing at Rome, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Can- Heading Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machinery for forming cans and the like.

One of the objects thereof is to provide a simple and efficient machine of the above general type adapted to place heads on can bodies.

Another object is to produce a machine of the above nature, several of the elements of which are readily adjustable with relation one to another.

Another object is to provide a machine of the above type having a capacity for performing its functions at a high rate of speed and having a maximum output in cans per hour.

Another object is to provide means in a can heading machine for rigidly pressing the heads into position and holding the same in such condition under a reduced pressure.

Another object is to provide means adapted positively to remove or strip the headed cans from the parts within which they rest.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the machine hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, wherein is shown one of various possible e1nbodi ments of my invention: Figure 1 is a side elevation of the same. Fig. 2 is an enlarged detail section taken on the line mm of Fig. 1. Fig. 3 is an enlarged plan of a portion of the supply chute. Fig. 4 is a side elevation of the upper portion of this embodiment of my invention showing the supply chute in its alternative positions with respect to Fig. 1. Fig. 5 is a front elevation of the central portion of the machine. Fig. 6 is a sectional elevation taken on line y 1 of Fig. 5. Fig. 7 is an enlarged detail sectional view taken on line 22 of Fig. 6.'

nature of certain features of my invention, it may here be noted that it is proposed toavoid uncertainty in action by providing rigid means for removing or stripping the headed can bodies from the parts in which they rest, injury to the cans being prevented by holding the same flexibly at the time at which the stripping takes place, thus guiding the cans and preventing rattling or displacement thereof. As these flexible holding means might be unsuitable efliciently to head the cans, separate unyielding means are provided for forcing the heads into position, subsequent to the action of which the above-mentioned flexible holding means are automatically brought into play. It is also proposed to increase the output of the machine by the provision of can-holding means so disposed as to permit the can-receiving jaw and means to lie closely together, thus increas- I ing the rate of production with a given peripheral speed, as will be pointed out more in detail hereinafter. The above are among the preferred constructions wherein the means of attaining certain objects of my invention are embodied.

Referring now to the embodiment shown in the accompanying drawings, there is shown in Fig. 1 a bed or base 1 provided with uprights or standards 2, these standards being positioned at each end of the machine, as is more clearly indicated in Fig. 5 of the drawings. Projecting upwardly from each standard 2 and preferably formed integral therewith is a rigid arm 3, these arms being connected at their upper ends as by a cross bar 4. Pivotally mounted upon this cross bar as by the straps 5 terminating in sleeves 6 is a chute 7 comprising broadly two portions 8 and 9 inclined with respect one to another. The upper portions 8 of the chute comprise side channels 10 adapted to receive and guide the separate heads or end pieces for forming can bodies, and between the inner walls 11 of these guiding channels is a third channel 12 of considerably greater width adapted to guide the bodies of the cans. The floor of this last-mentioned guiding channel comprises a pair of strips 13 supported and held in properly spaced relation to the channels 10 by means of the threaded tie rods 14 and sleeves l fitted thereon. Similar tie rods 16 connect the upper portion of the chute adjacent the bend thereof and straps 17 are bolted or tied to the inner walls of the guiding channels along the depending portion 9 of the chute. Also positioned along the portion 9 are the guiding bars 18 which are bolted in the position shown in Fig. 5 of the drawings, and prevent a displacement of the can bodies in a forward direction. The lateral straying of the heads of the cans is prevented by rigid guides 19 bolted to the straps 5 and having at their lower ends plates 20 for the purpose of properly guiding the can heads into the machine. Displacement of the bodies in a forward or upward direction at and above the bend of the chute is prevented by a fiat guide 21 bolted between the bars 18 as at 22 and curving upward and rearwardly over the chute. Bolted upon the lower portion of the chute at 23 and 24 are a pair of straps 25 similar to the straps 5 provided at their forward ends with forks 26 adapted to engage a cross bar 27 adjustably mounted within the arms 3 before described.

Upon each of the guides 19 is pivotally mounted an L-shaped lever 28, which is held in either one of the two alternative positions by reason of the engagement of a flat spring 29 fixed upon the guides either with the squared end or the side of the lever. These levers are so shaped and positioned as when swung into their inward position, shown in Fig. 2 of the drawings, to obstruct the passage both for the heads and bodies of the cans. In this manner, if it be desired to lock the cans in the chute for any reason, the same is readily accomplished merely by swinging the levers 28 into their innermost position, whereas in their normal position they permit a free passage for these parts, and as above mentioned, spring 29 is adapted to hold these levers in either their inner or their outer positions. The entire chute is thus pivotally mounted by means of the heavy straps 5 upon the cross bar 1 and may, if desired, be swung into the position indicated in Fig. 4c of the drawings, in which ready access to the machine is permitted and the feeding of the can heads and bodies stopped. hen swung downwardly into its normal position, however, as shown in Fig. 1, the forked straps 25 engagingthe cross bar 27 limit the movement of the chute in this direction and the chute may be locked in this position, in any desired manner. The function of the L-shaped levers abovedescribed should become more clearly apparent in this connection, inasmuch as, were it not for these parts when the chute is swung into a position shown in Fig. at, the can heads and bodies remaining therein would be discharged therefrom.

Referring now to Fig. 1 of the drawings, there is shown journaled within the standards 2 a shaft 30 having fixed upon one end a spur gear 31 intermeshing with a pinion 32 journaled upon a stud 83 preferably formed upon the frame of the machine. In fixed relation to pinion 32 and preferably formed integral therewith, is a pulley 31 driven by belt 85 from any desired source of power.

Mounted upon the shaft 30 are a pair of what may be termed disks 36, of which, as the two are identical, one only will be described. Disk 36 is provided with an extended sleeve-like hub, 37 split as indicated at 38, and adapted adjustably to be clamped to the shaft as by bolts 39. Formed within the disk is an opening 4-0 provided with an extended bearing 41 for a rod passing through a similar opening in the remaining disk. It will thus be seen that these disks are adjustable longitudinally and rotatably with respect to the shaft and yet are maintained in their desired angular relation by the rod 12.

Mounted above the circumference of the disks 36 are a series of can receiving members or cradles 43 each of these parts being provided with a depending flange 4% bolted to the disk. These members are provided with recesses or grooves 4:5 within which the head is to rest, formed of such depth as to properly space the edges of the head with reference to the edges of the body. It may here be noted that suitable slots 16 are provided so as to permit the passage of the guiding plates 20 above referred to, thus securely guiding the heads into their proper position within the receiving cra dles. As these can receiving members with the parts associated therewith are substantially identical, one only will be described. The outer portion of the member a3 of a hollow cylindrical form and has fixed therein an annular abutment 17. Positioned within this abutment is a guide rod 48 having a head or piston 49 adapted to rest against the inner walls of the abutment and thus limit the outward movement of the rod. The outer end of rod 18 is preferably rounded as shown at- 50 for a purpose hereinafter described. Secured upon rod 48 as by a pin 51 passing through the slot 52 is a collar fitting the inner surface of the outer cylindrical portion of the member 43 and adapted to slide therein. A heavy spring 51 coiled about the rod and taking against the abutment 47 and collar 53 normally holds the head 4L9 in its outermost position shown in Fig. 7 of the'drawings. Within a chamber formed in the rod 48 and having its outer end closed by means of a plug 56 positioned therein, is acoiled spring 57 which tends to force a plunger 58 slidably mounted therein against the pin 51. In this manner it will be seen that any pressure applied to the rounded end 50 of the rod 48 will force the same inwardly by direct pressure, whereas, a pressure in the same direction upon the collar 53 will act only through the spring 57 until this member is compressed so as to permit the pin 51 to strike the inner end of the slot 52. This action will be described more at length hereinafter.

Mounted about the cylindrical portion of the member 43 is a sleeve or slide 59 which is prevented from rotating thereon as by means of the pin 60 adjustably held in flange 44 by screw 61 and reciprocating within a passage 62 formed in the lower partof the sleeve. Upon the upper side of sleeve 59 as shown in Fig. 7 of the drawings, is a boss 63 having held thereon by means of screw 64 an anti-friction roller The inner side of the sleeve is shaped so as to form ways or guides 66 within which is slidably mounted a clamping member or jaw 67 which normally rests upon the outer portion of the member 43. It may here be noted that terms of the nature of in Wardly and outwardly are used with reference to the center of the machine as the innermost point. Tied to the upper end of the jaw 67 as by means of a screw 68 the movement of which is limited by shoulder 69 is an anti-friction roller 7 0, the function of which will be hereinafter described.

As shown in Fig. 6 of the drawings, a number of the above described receiving members, with the parts associated therewith, are positioned about the disks 36, the same facing inwardly toward one another, as shown in Fig. 5 and being spaced apart for a purpose hereinafter described. Also, each cradle or can receiving member 43 is provided with two lips 71 extending laterally toward the next adjacent cradle upon each side thereof for the purpose of bridging over the gap between these parts and preventing jarring or injury to the cans which might otherwise result.

Connected with the cross bar 27 as by means of the brackets 72 are a pair of guides 73 adapted to coact with the rollers as shown in Fig. 5 of the drawings. These guides are laterally adjustable upon the bar 27 and are secured to the standards 2 at their lower end by means of threaded rods 74 and nuts 7 5. As these guides with the parts associated therewith are identical, one only will be described in detail. Guide 73 which is, in general, of the cross-section of channel iron with the flanges turned inwardly, comprises

portions

76 and 77 lying within a plane taken through the rollers 65 with the sleeves 59 in their retracted positions. Intermediate these portions and connected therewith, as by the curved or

inclined portions

78 and 79, is a central portion 80 lying within the plane of the rollers 65 when at the innermost limit of their path of travel. It will thus be seen that as the sleeves 59 rotate with the shaft 30 the rollers 65 pass at each revolution into the portions 76 of the guides and are moved by the curved or inclined portions 78 inwardly so as to bring the sliding jaw 67 above the can body resting within the cradle 48. This position of the sleeve is maintained for a portion of the revolution of the shaft and the slides are finally retracted by the curved portions 79 of the guides. This cycle of operations is repeated with each revolution of the shaft.

Mounted upon guides 7 3 is a bracket 81 having pivotally mounted thereon the guide 82. This guiding member is adjustable with reference to guide 7 3, as by means of bolt 83, within a curved slot 84 in a bracket 85 hereinafter referred to. It will thus be seen that by means of loosening the bolt 83, the guide 82 may be swung about its pivotal connection with the bracket 81 and secured in any desired position. Formed upon guide 82 are flanges 86 and 87 respectively adapted to co-act with the opposite sides of the rollers 70, thus alternately depressing and raising each sliding jaw 67 according as the corresponding roller engages one or the other of these flanges. It will be noted by reference to Fig. 5 of the drawings that the central portion of the guide 82 is free from guiding flanges, thus leaving the jaws without positive control from the guides at this point.

Mounted upon the standards 2 by means of rigid arms 88 is a heavy cross bar 89 upon which is mounted a cylinder 91 having fixed at its upper end a collar 92 within which a guiding rod 93 fixed to a piston 94 is adapted to slide. A heavy spiral spring- 95 is preferably compressed between the piston 94 and the fixed collar 92 tending normally to hold the former in its outermost position with reference to the cylinder.

Rotatably mounted upon the cross bar 89 as by means of sleeve 96, is a lever 97 abutting, through the set screw 98 held in position by the lock nut 99, against the face of the piston 94. The lower end of this lever is bifurcated and within the arms 100 thereof is journaled a roller 101. The downward movement of the lever is limited by means of a set screw 102 mounted within a lug 103 in fixed relation to cylinder 91 and projecting between the arms 100 of the lever and engaging a lug 104 formed thereupon. In this manner the compressed spring 95 tends by means of the set screw 98 to rock the lever 97 about the cross bar and thus force the roller 101 toward the center of the 4 machine, such movement being adjustably I limited by means of the set screw 102 as above indicated. Roller 101 is so positioned as to be directly over the upper or outer ends of the slidable jaws 67 when the same are forced into their inner position by means of the guide 82, these ends being curved about the shaft as a center. In this manner as the jaws are released by the flanges upon guides 82 they are subjected to a readily adjustable elastic pressure transmitted thereto through the rollers 101, thus holding the same firmly in their depressed position while the can is acted upon as hereinafter described.

The means for actuating the rods or plungers 48 in the desired manner preferably comprise the following parts. As these means are identical upon both sides of the machine, that upon one side only will be described. Journaled within a cross bar 105 connecting the

rods

106 and 107, which are adjustably positioned upon the standards of the machine by means of nuts 108, is a roller 109 the inner portion of which projects within the path of travel of the rounded outer ends of the plungers 48 when the same are in their normal ret acted position. As these plungers are swung into engagement with the roller 109 they are successively forced inwardly to a position indicated in Fig. 5 of the drawings. After passing a point opposite this roller the collar is engaged by the flanges 110 of an abutment 111 held in position upon the standard as by means of

adjustable rods

112 and 113. This abutment is curved about the shaft 30 as a center and comprises a member of substantially U-shaped cross section, the two flanges thereof being adapted to engage the collar, whereas the curved connecting port-ion permits the rounded end of the plunger to pass freely. In this manner the plunger is maintained in its innermost position under a flexible pressure exerted through the spring 57 shown in Fig. 7 of the drawings. Upon passing the lower end of the abutment the collar is freed and the entire plunger and associated parts retracted by means of the heavy coiled spring 54.

Adjustably mounted upon the frame of the machine, as by means of the slotted links 114 and bolts 115 the former being connected by a cross rod 116, is a chute 117 comprising upper and

lower members

118 and 119 and side members 120 held in fixed relation thereto as by means of tie rods 121. The member 119 projects upwardly to form what may be termed a stripper arm 122, this part being positioned between the opposing cradles 43 and being adapted positively to remove the cans from these members as the same are swung into their iowermost position, reference being had to Fig. 6 of the drawings.

In order to aline the members 59 in their retracted positions, there is formed within the guiding member 43 a recess 123 having therein a spring 124 normally tending to hold a ball 125 within a corresponding recess in the sleeve 59. This device, while permi'tting a substantially free movement of the sleeve, nevertheless, by forcing the ball within the recess therein, tends to hold the same exactly in the desired position when retracted, as is most clearly shown in Fig. 7 of the drawings. A similar device is provided for exactly positioning the sliding jaw 67, the recess 126 formed within the jaw having therein spring 127 and ball 128 adapted to co-act with a recess 129 in the guide 66. The outward movement of the jaw is limited by means of a screw 130, the inner end of which co-acts with a slot 131 formed in the guide 66. The movement of said jaw when the same is moved laterally inwardly is limited by abutments 132 formed within the upper side of the member l3, as best indicated in Fig. 8 of the drawing.

The operation of the above described embodiment. of my invention is substantially as follows: The several can bodies are positioned within the central channel 12 of the supply chute 7, and the corresponding heads occupy positions in the side channels 10, as

above described. Assuming the machine to be in rotation, driven as above described, the can receiving members or cradles pass the lower end of the chute and each receives therefrom a can body with the two corre sponding heads positioned. opposite thereto. Immediately after receiving these parts the sleeve 59 is thrown inwardly by means of the rollers 65 co-acting with the curved portions 7 S of the guides 73 and the jaw 67 is then depressed upon the can by means of the flanges 86 upon guides 82. The smooth upper surfaces of the jaws then pass beneath the spring-pressed rollers 101 and are firmly held downwardly upon the can bodies while the plungers 48 are forced inwardly by rollers 109 as above described, this movement driving the heads upon the body of the can. The plungers are thereupon flexibly held in their innermost position by means of the abutments 111, being thus prevented from rattling or straying while the jaws G7 are raised by the flanges 87 and the sleeve 59 retracted by the curved portions 79 of guides 73. This flexible pressure is brought to bear upon the can heads by virtue of a slight movement of collar 53 relative to the plunger 50 caused by the engagement of this member with the abutment 111. Collar 53 being pressed inwardly moves the pin 51 within the slot 52 and through spring 57 exerts the desired pressure. The can is thus not only prevented from rattling or straying, but the effect of slight inequalities in length is readily compensated for. The

headed can then comes into contact with the rigid stripper arm 122 and, being held in position merely by the flexible pressure exerted through spring 57 as above described, is readily drawn from the cradle and discharged into the chute 117. This cycle of operations is repeated for each can body and, as the can receiving members may be positioned closely together owing to the peculiar movement of the jaw 67, a high rate of production of the machine is attained with a relatively low peripheral speed, the production in machines of this class often being limited by the peripheral speed of the rotating parts inasmuch as it is necessary with a gravity feed, that the bodies drop into the can receiving member.

It will thus be seen that I have provided a machine eminently adapted to accomplish the objects of this invention and possessing advantages many of which will be apparent from the above description and many of which can be appreciated only by the actual use of the same. The several parts are, as above pointed out, readily adjustable to acconnnodate articles of different sizes and the operation of the machine is almost entirely without jar, the engagement of the moving parts with the fixed members with which they coact being cushioned as by means of the rounded corners upon the upper ends of jaws 67 and upon the outer surface of the collars 53. The pivotally mounted chute, moreover, is a feature of considerable value, inasmuch as it renders all parts of the machine readily accessible, and the positive stripper arm is far more satisfactory in action than the unreliable ejecting means which have been in somewhat general use. The feature of my invention, moreover, whereby the heading action is accomplished by an unyielding and forceful movement and yet the headed can is thereafter maintained in the desired position by a flexible and readily adjustable pressure upon the heads thereof, is of marked importance. The flexible pressure upon the jaws at the moment of heading is also of material value as any desired pressure may thus be applied independent of wear of parts or variation in the size of the can. It will also be noted that I have provided means whereby the entire series of receiving members upon one side of the machine may be adjusted without changing their relative positions with ref erence one to another. In this manner the can receiving members upon the two sides of the machine may be adjusted so as to be in proper alinement with a minimum of effort and waste of time.

It may be noted that the term can receiving is used throughout this specification and in the following claims in a broad sense as descriptive of any part or parts It may also here be noted that the expression operative portion as used throughout the following claims with reference to can receiving means denotes that part within which the can is to be positioned.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
