4CAN-Hsatinata MACHINE.

SPECIFICATION forming part of Letters Patent No. 540,366, dated J' une 4, 1895.

Application filed April 24, 1894.

To 1f/ZZ whom, t my'concern:

Be it known that I, HENRY SCHAAKE, aoitizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Can-Heading Machines; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention relates to a certain new and useful machine for applying tight fitting heads upon the outside of the ends of can bodies, or to that class of machines known as outside headers, which consists in the arrangement of parts and details of construction as will be hereinafter more fully set forth in the drawings, described and pointed out in the specication.

The present invention has for its object to accomplish mechanicallythe work performed in the can heading device secured to George A. Marsh by Letters Patent of `the United States No. 152,757, granted on the 7th day of July, 1874; that is to say, that by the machine herein shown and described the can head is applied to the can body by causing one end of the can body to be first inserted within the ange of the can head at an angle thereto, after which the body is gradually brought into a horizontal position, which causes the end to be headed to be tilted or forced over until the entire circumference o f the can body has entered within the flange ot the can head, which applies one head to thercan body, after which the opposite or free end of the can body is likewise tilted or moved into the iange of the opposite can head, the can thus` being' headed in the same manner as described in the Marsh Letters Patent No. 152,757, the difference being that by the use of tho present machine the can body is placed within the flange of the can head automatically or mechanically, whereas in the Marsh patent, aforesaid, the can body is forced within the flange of the can head by hand, the Marsh device being a mere hand tool, while the present invention is a complete operative machine designed to place a tight fitting exterior head upon can bodies with rapidity.

Serial No. 5 0 8.8 5 9. (No model.)

In both the Marsh hand tool and the present machine the body is applied to the can head by first placing a portion ofthe outer edge of the can body within the fiange of the can head at an angle thereto and thence tilting the can body over until the entire circumference of the body is forced within the flange of the can head.

In order to more fully understand my invention reference must be had to the, accompanying sheets of drawings, wherein- Figure 1 is a side elevation of the machine, showing only a limited number of can-bodyclamping jaws. Fig. 2 is a side elevation of one of the slotted cam-plates for raising and lowering the clam ping-jaws. Fig. 3 is an end elevation of the machine viewed from the feed end. Fig. 4 is a top plan View of' the slotted plate for imparting lateral movement to the can-body-clamping jaws, so as to place the end of the retained can-body within the flange of the can-head. Fig. 5 is an enlargedid'etailed view of one of the links or frames which constitute the endless carrier and one of the clamping-jaws for the can-bodies. Fig. 6 is a view similar to Fig. 5, showing position of the can-body-clamping jaw when tilted or swung so as to place the lower edge of the can-body within the flange of the cau-head. Fig. 7 is a similar View showing position of the canbody-clamping jaw after one head has been applied thereto and prior to the jaw having been tilted to a position opposite to that illustrated by Fig. 6 in order to receive the opposite can-head. Fig. Sis a sectional elevation of the mechanism illustrated by Fig. 7, taken on line a: of said figure and viewed in the direction of the arrows. Fig. 9 is a detail top plan of one of the can-head holders or seats. Fig. 10 is a detail View of the canbody-clamping jaw closed. Fig. ll is a similar View of the can-body-clamping jaw when open. Fig. 12 is a detail side elevation of one of the retaining plates, blades, or paddles for the retained can-body, shown in a lowered position. Fig. 13 is a similar view of the plate, blade, or paddle when in a raised position. Fig. 14 is a top plan view of one of the links or frames constituting the endless carrier-chain. Fig. 15 is an enlarged side view,

in elevation, of the segment-cam for opening ICO , may be cast integral or separate as desired.

These plates or side pieces may be said to constitute the frame of the machine.

Between the side plates or frame I locate the disks or wheels C, C, which are secured upon the cross shafts or axles B2, B3, one at each end of the frame, as shown by Fig. l. The forward shaft B2 constitutes the drive shaft, it having secured to the outer or projecting end thereof the belt wheel C2, which is driven by means of a belt pulley. Not shown.

Over the wheels C, C', travels the endless carrier chain or belt which consists of a series of rectangular open frames united together. These frames each carry clamping jaws for the can bodies.

One of the rectangular open frames is pro vided with a male section of a hinge joint, c, while the opposite one is provided with a female section, c', which sections, when fitted together, are united by a bolt c2.

In order to' provide for a positive travel of the endless carrier belt or chain and prevent slipping thereof, I cast the disks or wheels C, C', of a heXagon-'shape, thereby providing a series of faces b', each of which is separated by the notch b2, within which notched portion the knuckles ofthe hinged joint of the frames of the carrier chain lit or rest while the frames bear upon the flattened faces of the disks or wheels C, C.

From the ends of the truck frame project the pins c3, upon which are secured the rolls h. These rolls work within the channels or guide grooves ct cut within the inner face of the side pieces A', A2 of the frame and serve to support the endless carrier chain or belt while traveling between the carrier wheels, and bear upon the flanges ct of the curved end pieces, after leaving the guide grooves or channels, thus acting as supports for the truck frames of the endless carrier belt or chain. These open frames, which when hinged together constitute the endless carrier chain or belt, have the dovetailed grooves d out within the inner face and crosswise thereof, within which tit and work the slide frame D, see Fig. S, said frame being an open one and rectangular in shape, but smaller in size than the opening of the rectangular frame C3, so as `to permit of lateral movement.

Within the rectangular slide frame I cut four openings d', through which work the rods D', D2, four in number. These rods are connected in pairs, at their top, by the brackets D2, Dj, at their lower ends by plates E, E. These rods have a vertical movement, but each pair move independent of the other. In order to secure a long bearing for the rods D',

D2, I secure to the frame D, the bosses e, through which the rods extend, as shown in Fig. '7. j

Within the brackets D3, D4, there is hung, by means of trunnions e', e the swinging frames E2, E2, which frames are provided with the downwardly extending hollow sleeves F, F. 'lhesc swinging frames are providedl with inwardly projecting hollow bossesf, between which the sections F2, F3, of the clamping jaws are secured by means of the bolt F4. The lower end of each jaw section is connected to the vertical rod G, by link c, thus forming a toggle joint connection. The rod extends downward through and below the open slide frames D, and serves to open or close the sections of the can body clamping jaw as raised or lowered.

Through the hollow sleeves F, F work the vertical rods Si', G2, the upper ends of which rods terminate in a plate, blade or paddle G3, G4. These plates, when raised, bear against the end of the can body, retained within the can body clamping jaws, and prevents the displacement thereof during the operation of placing a head upon the body. These plates may more properly be termed can body retaining plates, blades, or paddles. The rods raise and lower alternatively. Said rods are so placed within the hollow sleeves as to permit of a direct upward movement until the retaining plates, blades or paddles carried thereby have passed beyond the lower surface or edge ofthe can body, after which they gradually move inward until the end of the can body opposite to that about to receive a can head is engaged by the retaining plate. This is necessary, for did the plates, blades, or paddles move their full lift in a direct line they would have a tendency to catch the lower edge of the projecting portion of the can body, for the reason that the can bodies do not always seat themselves in the same place within the clamping jaws. However by providing for the plates, blades, or paddles being carried above the lower surface of the can body prior to engagement therewith this diiculty is overcome. This second movement of the rodsG, G, which throws the can body retaining blades, paddle or plates, is accomplished by providing the hollow sleeves with the inclined shoulders g', g2, which are engaged by the inclined lugs 7i., h', projecting from the said rods.

After the rods have been lifted a given distance, sufficient ,to cause the retaining plates, blades or paddles to clear the edges of the can body held within the can body clamping jaws, the inclined lugs ride upon the inclined shoulders and thus force the rods moving upward toward the projecting ends of the can body held within the can body clamping jaws. The rods when raised are held in their lifted position by the pressure of the springs G5 thereagainst, which springs are secured within the hollow sleeves. See Figs. l2 and 13.

Bysecuringtheclampingjaws within swing- IOO IIO

ing frames I permit the jaws to be tilted or swung at an angle to the sliding frame without the necessity of said frame'being tilted therewith. As will be noticed by reference to Fig. 6, the clamping jaws for the can body are so secured to the frame as to permit of the same swinging upon an axis horizontal to the said sliding frame.

From the plates Ior bars E, E which connect the lower end of the lift rods, outwardly project the arms H, H. These arms work within the shouldered slots of the cam plates H2, H2. These cam plates run parallel, a distance apart, as shown, and are supported by means of the shafts B2, B2. Inasmueh as the slots within which the arms H, H travel eX- tend the entire length of the said cam plates, it is necessary that they be cast with the ribs H.4 in order to unite the sections of the cam plates, else the cam plates must be cast in sections and the ribs riveted thereto. It will be noticed that the slot in each plate is made so that as one arm is elevated, so as to raise the lift rods on that side of the machine, the

opposite arm is lowered.

Referring to the plates H2, H3, see Figs. 1 and 2, it will be observed that from point 1 to 2 the slot of each cam plate is upon a level, so that when the arms H', H2 travel within this portion of the slotted cam plates the clamping jaws for the can body, and connecting parts, will be elevated to the position illustrated by Fig. 5. From point 2 to 3 theslot of cam plate H2 is cut upon a downward incline from point 3 to 4 upon a straight line or level, from pointf1 to 5 upon an upward incline, from 5 to 6 on'a level orstraight line, from 6to 7 at a slight downward incline, from 7 to 8 on a level or straight line, from 8 to 9 at an upward incline, from 9 to 10 ona level, from 10 to 1l ata downward incline and from 11 to the end of the cam plate on a level or straight line, while the slot in cam plate H3 from point 2 to 12 is run at an upward incline, from 12 to 13 on a level, from 13 to 1-1 at a downward incline, from 14 to 15 on a level, from 15 to 16 at a downward incline, from 16 to 17 on a level, from 17 to 18 atan upward incline, from 18 to 19 on a level, from 19 to 2O at a downward incline and from 2O to end of the cam plate on a level. It will thus be noticed that the slot in cam plate H3 is run very nearly the opposite of that of the cam plate H2. Consequently when one set of lift rods is raised or elevated by the arms thereof traveling within the slot of one of the cam plates, the opposite pair of lift rods will be lowered.

From the rectangular frame C3 upwardly extend the curved arms I, I,the ends of which terminate in a semicircular can head seat or holder I2, l2. Within the upwardly projecting

shoulders

14,15, I cut an elongated opening 7L, through which projects the bolts 7L, h4, by means of which the upper ormovable half I, I7, of the can head holder is secured. The bolts h, h4 carry the rolls h2, h2, which raise the movable section of the can head holder as hereinafter set forth. The movable portion of the can head holder has a semi-circular can head seat or socket cut in the rear face thereof, which, when the said section isl lowered, conforms with the semi-circular seat or socket cut within the lower section and serves to complete the annular seat for the can head.

The outer face of the movable sections of the can head holder I cut away or chamfer, as shown at k, so as to permit the upper edge of the can body -to be gradually gathered in as the projecting end of the body is forced within the flange of the can head retained within theannnlar seat or socket of the can head holder. In this respect, that is, the providing a semi-circular chamfered plate for guidance of the end of the can body within the flange of the can head. my seat is the same as that set forth in the Marsh hand tool or device covered by Letters Patent No. 152,757.

Within each movable section of the can head holder I cut the opening 7a4, which permits the heads dropping from the can head feed chutes K, K directly into the can head or socket of the can head holders. The movable section of the can head holder I2 is raised as the forward movement of the endless carrier carries the roll h2 up the inclined face of fixed cam K2, held in line therewith by curved bracket 7c3, secured to the frame of the ma chine. See Figs. 1 and 3. The movable section of this can head holder is held raised until said roll has traversed'the level portion of the said cam, during which travel the headed end ot' the can body is withdrawn from within the can head holder. As the roll moves Voff the opposite end of the cam, which is downwardly inclined, the movable section is gradually lowered or closed.

To one side of the machine I secure the slotted plate J, which plate runs the entire length of the machine and the slot therein is s0 cut that the roll j, secured'to the downwardly extending pin j projecting from the sliding frame D, during its travel therein will serve to shift the sliding frame D from side to side of the rectangular frame of the endless carrier in accordance with'which end of`the can body is being headed. As will be noticed this slot runs from point 2l to 22 in a straight line, thence-at an outward incline to point 23, thence in a straight line to point 24, thence at an inward incline to point 25, thence in a straight line to point 26, thence at an 'inward incline to point 27, thence in a straight line to point 2S, thence at an outward incline to point 29, and from there to the end of the plate in a straight line.

At each end of the machinel locate the segment shaped cams L, L', the formerof which is keyed to the shaft B2, which extends through itshub, Fig. 3. The shaft B2 isa non-rotating one, the disks or wheels at` the feed end of the machine being loosely. securedupon said shaft. Segment cam L is located at the IOC Ito

forward end of the machine', the drive shaft B2 passing through the hub L4 thereof, which is bolted to the flanges Z4, Z5 projecting from the hubs L5, L6, respectively, of the slotted cam plates H2, H2, through which hubs extends the shaft B2. Fully shownin Fig. 16. As the roll Z, laterally projecting from the rod G, is carried over the inclined face of the segment cam L, during the travel of the endless carrier chain, the rod G is raised, which closes the clamping jaws `around the can body L2, fed therein from the feed chute L2. As the clamping jaw is carried over the disks or wheels secured' to the drive shaft B3, after the can body has been headed, the roll Z is carried beneaththe flange m inwardly projecting from segment cam L', which gradually draws the rod G downward and opens the clamping jaws-so as to discharge the headed can body into the runway M. The clamping jaws are opened and closed through the medium'of the toggle joint connection before described. y

After the clamping jaws have been closed around the can body in order to true and round the same so as to correspond to the interior diameter of the can head flange, it becomes necessary that the clamping jaws with the ends of the can body projecting there'` from, be raised so as to be in line with the flange of the retained can head M This rais ing of the can body is accomplished through the medium of the lift rods D', D2, as the arms H', H, projecting from the connecting plates E, E work within the slotted cam plates H2, H2. As the arm H travels from point 2 to 3 the rods D are lowered, which carry that side of thecan body clamping jaw therewith, while the rods D2 are raised by the arm H traveling over the upwardly inclined portion of slotted cam plate H2, or between

point

2 and 12. This travel of the carrier belt or chain causes the clamping jaws to assume an inclined position to thel can head holder or clamp,as

illustrated by Fig. 6. While the clamping jaws are being swung or tilted atan angle, the slide frame D is drawn over or forced to slide within the rectangular open truck frame by the roll j riding upon the outwardly in-r clined portion of the slotted plate J, or between the

points

22 and 23. The drawing over of the slide frame causes the lower edge of the projecting end of the can body to move within the flange of the retained can head. See Fig. 6. Prior t0 the tilting of the clamping jaws the roll m secured to and projecting laterally from lift rod G', rides upon the inclined fixed cam N, secured to plate H2, and forces upward or raises the said rod within the hollow sleeve F. This movement of the lift rod causes the retaining plate, blade, or paddle G2 to move in front of the projecting end of the can body, as shown in Fig. 6. As the clamping jaws and their connecting parts are carried forward, arm H travels upon the level portion of the slotted cam plate H3, or from point 12 to 13, while arm H travels over the upwardly inclined portion of the slotted cam plate H2, or from point 4 to 5, the distance from 3 to 4, or level portion having been traversed while the frame D was being drawn over in order to place lower edge of the proj ecting end of can body within can head flange. As the arm travels upon this upwardly inclined portion of the slotted cam plate H2, the right hand side ofthe clam-ping jaws are gradually elevated or raised until the can body assumes a horizontal position. This raising of' the can body to a horizontal position gradually tilts or forces the upper left hand edge of the projecting end of the can body within the flange of the retained can head.

After the projecting end of the can body has moved within the flange of the can head the roll h2 rides upon the inclined face of the cam K2 and causes the movable section of the can head holder I2 to move outward so as to permit the withdrawal of the headed end of the can body. This withdrawal of the headed end of the can body is accomplished by the roll j traveling within the inwardly inclined portion of the slotted plate J, or between the

points

25 and 26. The raised retaining plate,

blade or paddle G3 bears against the free proi jecting end of the can body in order to prevent lateral displacement thereof as the opposite end is forced within the flange of the retained can head. As the roll h2 moves from off the cam K2, the movable section ofthe can head holder l2 is closed gradually. The position of the can head holder and clamping jaws for the can body, after the movable section hasjbeen raised and the headed end of the can body removed, is clearly shown in Fig. 7, it being a horizontal one.

As the clamping jaws are thrown into a horizontal position and the headed end of the can body removed fromwithin the can head holder, the retaining blade, plate or paddle Gs is lowered so as to be below the edge of the can body in order to permit the free or unheaded end of the can body to enter the can head iiange retained within the can head holder l2. Prior to the entrance of the unheaded end of the can body within the flange of the can head retained Within the can head holder I2, the retaining blade, paddle or plate G4 is raised or elevated so as to move above the level of the lower edge of the projecting end of the can body and press against the outer face of the head placed thereon for the purpose of' holding the can body firmly in place while a can head is being secured upon the opposite end of the can body. This retaining plate, blade or paddle is raised by the lifting of the rod G2, caused by the roll m2 rieding upon the inclined face of the fixed cam N. As this rod is being lifted to elevate the retaining plate, blade or paddle G4, the rod G is lowered by the-roll m traveling beneath the flange m2 of downwardly inclined fixed cam N2. Consequently when retaining plate G3 has moved its full downward distance, re taining plate, blade or paddle G4 will have movedvits full upward distance. The cam N IOO IIO

projects upwardly from plate H3, while the cam N2 is secured to and upwardly projects from plate H2. See Fig. 1.

During this raising and lowering of the retaining plates, blades or paddles the clamping jaws for the can body are being carried forward in a horizontal position until arm I-I rides upon the upwardly inclined portion4 of the slotted cam plate H2, or from point 8 to 9, when the lift rods D are forced upward, which likewise elevates that portion of the clamping jaws connected therewith by means of the bracket of the lift rods D, while the opposite end or headed portion of the can body is thrown downward at an angle by the lowering of the lift rods D2, said rods being carried downward by the arm II traveling within the downwardly inclined portion of the slotted cam plate H5, or from point l5 to 16. This upward and downward movement of the lift rods causes the clamping jaws to swing at an incline or angle, the free or unheaded portion of the can body, projecting beyond the clamping jaws, being elevated, the position of thecan body and clamping jaws being the opposite to that illustrated by Fig. 6. As the clamping jaws are being swung or tilted from a horizontal position to an inclined one, the same is forced over to the side of the machine, that is, to the right hand side, the left hand end of :the can body having been headed, by the rollj traveling within the inclined portion of the slotted plate J, or from point 26 to 27. This inward travel of the roll j causes the slide frame D to move within the lower edge of the unheaded end of the can body within the flange of the can head held within the can head holder I3. With the continued forward travel of the endless carrier belt or chain, the arm H rides upon the upwardly inclined portion of the slotted cam plate H3, or from point 17 to 18, which moves the lift rods D2 upward, said rods carrying the clamping jaws therewith, through its connecting parts, until the same hangs in a horizontal position. As the clamping jaws are thrown,` into a horizontal position the upper edge of theunheaded portion of the can body is caused to move within the flange of the retained can head. It will thus be seen that the can body is headed by inserting the lower edge of the can body within the can head flange and thence tilting the can body over until the entire circumference of the can body has moved within the flange of the can head, in this respect beingbeyond cam K2. See Fig. 1. VAs the can head holder I3 is opened the clamping jaws for the can body are drawn to the center of the machine so as to withdraw the headed end of the can body from within the can head holder, by

the roll j traveling within the outwardly inclined portion of the slotted plate J, or lfrom point 28 to 29. This withdrawal of the headed end of the can body takes place while the roll h3 is traveling upon the level portion of cam K3. The travel of roll m2 beneath the flange of downwardly inclined fixed cam N3 moves rod G2 downward, which carries the retaining plate, paddle or blade G4 below the level of the can body. As the truck frame carrying the headed can is carried over the wheels or disks C C toward the discharge chute M, the roll Z, of clamping jaw lift rod G travels under the flange ot' the downwardly inclined fixed cam L and thus causes the rod to move downward, which movement of said rod gradually opens the clamping jaw and permits the headed can to be discharged into the discharge chtite.

It will be understood that the mechanism herein described, as relates to the sliding frame, lifting rods, clamping jaws, and retaining plates, I secure to each of the truck frames. Consequently it will readily be seen that the capacity of the machine is only limited by the number of truck frames made use of to constitute the endless carrier belt or chain and the rapidity with which the endless carrier is caused to revolve or travel.

So far as I am aware I am the first to devise a machine for automatically applying a tight fitting outside head to each end of a can body, provided with clamping jaws for receiving and holding the can bodies during the operation of heading, can head holders, and devices for throwing the clamping jaws .at an angle to the can head holders, the head being applied by first throwing the clamping jaws at an angle to the can head holders and moving the same laterally so as to place the lower edge of the can body within the flange of the can head while the can body is held in an inclined position, and thence forcing the entire circumference of the can body` within the flange of the can head by bringing the body into a horizontal position. Consequently I wish to be understood as clai ming broadly this feature.

I am aware that minor changes may be made in the arrangement of parts and details of construction without departing from the nature and scope of my invention.
