CAN-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 371,493, dated October 11, 1887.

(No nrulel.)

To (LZZ whom it may concern:

Be it known that I, EDWARD J. DOLAN, a citizen of the United States, residing at Philadelphia,in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Can-Making Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon,whieh form a part of this specification.

Like letters and figures refer to the same parts throughout the several views.

This invention relates to can-making machines; and it has for its object to provide an organized machine, in which the blanks fed in at one end are turned out in the form of completed cans, the steps necessary to the formation of such cans following each other in rapid succession in one and the same machine. The novelty lies in the peculiar combinations and the novel construction, arrangement, and adaptation of parts, whereby the desired end is accomplished, all as more fully hereinafter described and claimed.

In the accompanying drawings I hate found it necessary,in order to properly illustrate my device, to represent the same upon such a scale as to require the separation of some of the views. Consequently, in some cases, two sheets of drawings will have to be looked upon as constituting but a single figure. For instance, Figures 1 and 1 represent aside elevation, partly in section, of a can-making ma chine constructed in accordance with my invention. Figs. 2 and 2indicate a top plan of the same. Fig. 3 is a sectional detail of the seaming device, more particularly hereinafter referred to. Fig. 4 is a sectional detail, on a horizontal plane, of the feeding and expanding devices. Fig. 5 is a cross-section on line 5000 of Fig. 4, showing, also, the construction and operation of the clamping-jaws. Figs. 6 and 7 are a plan and side view, respectively, of a portion of the mechanism for placing and soldering the tops and bottoms of the cans. Figs. 8 and 9 are plan views of a continuation of the same. Fig. 10 is a detail side view of the soldering-hopper mechanism. Fig. 11 is a detail section of one of the can -holding clamps. Fig. 12 is a detail section of the mechanism employed for supplying gas and air to the soldering'irons. Fig. 13 is acrosssection through the die-operating mechanism. Fig. 14 is a detail in end elevation of the jaws H.

Referring to the details of the drawings, A designates the base of the main frame, rising from the extreme front end of which are the standards a, in which is journaled the transverse shaft A, carrying the pulleys A Journaled in suitable boxes on the rearward projections, to, of the standards A, which rise from the base-plate, is the transverse shaft A, carrying the pulleys A around which and the pulleys A passthe endless conveyers or chains A, provided at regular intervals with projections a", for a purpose hereinafter explained.

Upon the outer end of the shaft a is the pulley at, around which and the pulley a, carried by the shaft A suitably journaled in boxes upon the front face ofthe standards A passes the endless chain a". Upon this shaft A are also secured the pulleys a around which and the pulleys a upon the shaft A secured in suitable boxes on the arms A, to ward the rear of the machine, pass the endless conveyers or chains a provided with projections similar to those upon the convoy ers a, j nst described.

Motion is imparted to the shaft A by means of the drive-pulley A on said shaft, and designed to be connected with any suitable source of power, (not shown or, if preferred, the said conveyer may be operated from the shaft 0 by means of the connections shown in dotted lines in Fig. l, in which is a pawl engaging a ratchet-wheel, 31, on the shalt A, said pawl being operated by suitable conncc tions with the shaft 0*, as shown.

The blanks B, which have been previously stamped out by a suitable die, which cuts out the covers, leaving openings 1) at opposite ends, as shown in Fig. 2, are placed upon the conveyers A, the projections a of which engage said openings, as shown in said Fig. 2. These blanks are carried along by said conveyors until thcy arrive beneath the cutting-die C. This die is carried by a cross-head, O, suitably guided in the guides c on the standards A and operated by suitably-timed cams 0 upon the transverse shaft 0, journaled in the standards A Beneath this die, suitably supported by said standards, is the female die or block B. The conveyers A pass between the top of this female die and the projections 1), formed on or attached to the standards A, which projections are for the purpose of preventing the blanks froinbeing carried upward by the die 0 after the blanks forming the can-bodies have been cut from the blanks Bf These blanks as they are cut fall through the opening in the female die onto the conveyer a to which motion is imparted through the medium of the pulleys a a and the chain a To impart an intermittent motion to the conv'eyer a I have provided the following mechanism: Upon the end of the shaft A I secure a ratchet-wheel, D, and'upon the corresponding end of the shaft 0 I secure a heart-shaped cam, 0*. Pivoted to the standards A at this side of the machine, is a bell-crank lever, B, one end of which carries a pin, d, working in the cam-groove in the cam C, while to the end of the other arm of this bell-crank is pivotally secured the lever D formed with or carrying at its free end a pawl, (2 engaging said ratchetwheel. t

D is a spring connecting the adjacent ends of the lever D and the arm of the bell crank, to which it is pivoted.

Any suitable means may be provided for conveying off the scrap-tin from the couvcyer A to prevent its falling upon the conveyors a In the drawings 1 have shown one means, which consists of a table, 32, secured to the frame of the machine in such a position as to receive the refuse or scrap-tin from the conveyor; but while I have shown this form I do not intend to limit myself thereto, as it is evident that various other means may be provided for this purpose without departing from the spirit of my invention.

Rising from the bed-plate are the standards E, in the upper ends of which is journaled the shaft E, carrying the pulley E, connected by suitable belt or chain with the wheel E on the shaft 0, as shown in dotted lines. Upon this shaft E is the cam E", shaped to operate the seaming-die E at stated intervals. This seaming-die is operated substantially in the same way as that shown and described in my patent, No. 353,737, dated December 7, 1886, but is constructed differently in the following particulars: The die proper, e,is of usual construction. The die 11 is recessed vertically, as shown at e, and within this recess, at the lower end thereof, is pivoted the die-holder 0 with its bent end 6 slotted, as shown at e, in which is removablyand adj ustably secured the die 6, which, it will be observed, is set at an angle to the die proper, e. The upper end of this die-holder is attached to or connected with a sliding plate, 6 moving in suitable guides on the top of the die, and provided with a pin, e working in a cam-groove, e in the cam E on the shaft E, all so timed that as the die descends the supplemental-(lien is forced downward at an angle to force the tin into the an- The can-body blanks are clamped around the mandrel F by means ofclamping-jaws F, which are similar to and operated in the same manner as those described in my patent, No. 345,284, dated July 13, 1886, and therefore need not be further illustrated or described in this application. 7 v

The mandrel F, a cross-section of which is shown in Fig. 5, to which, and to Fig. 4, especial attention is now directed, is at its front end cored out, as at f, and upon its side is provided with an undercut groove, f, in which the barf is re'ciprocated by the mechanism shown and described.

In order to expand the cylinder before it has been operated upon by the die, in the man-. ner above described, so as to allow it to move freely upon the mandrel, and to provide sufficient metal for forming the scam, I place within the cored-out portion of said mandrel a rod, F", provided upon its inner end with the eccentric-pin F. This pin engages the bifurcattionsf of the arm F, secured to the shaft E, which is suitably journaled within a recess formed in the under side ofthe mandrel. This shaft carries the wing or segmental arm F which, when in its normal position, in which position it is represented in Fig. 5, forms or completes the circular form of the mandrel, as shown in said figure. The outer end of this rod F? has rigidly secured to it one end of the connecting-rod F the opposite end of which is pivotally connected to the vertical connecting-rod Ff, which is made adjustable, preferably as shown in the drawings, in which it is represented as composed of two parts connected together by a turn-buckle or adjustingscrew. The opposite end of this link F is pivotally connected to one end of the lever F fulcrumed atf" on the lngf projecting from the standard E near its base. The opposite end of this lever is provided with a pin,f working in the cam-groove f of the cam f which cam is operated from the shaft E by means of the rod F 9, cam F? on the shaft E, and the intermediate connections shown, all so timed as to rock the shaft F and cause the wing F to be thrown outward, as shown in dotted lines in Fig. 5, which slightly expands the tin and'tightens or draws together the .seam. The outer end of thesliding barf has pivotally connected to it at one end the lever f fulcrumed atf on the lug f on the front face of the standard E. The opposite end of this lever is pivotally connected, as at f, to the rod f, the opposite end of'which is pivoted to the rod F" so that the cam f serves to operate the expander. The rod f serves, by reason of its connectionwith the rod f through the medium of theintermcdiate mechanism above described, to throw forward the barf, which, by reason of the engagement of its lug or catch f, pushes forward the cylinv groove h of the cam der on the mandrel, so that it may be operated upon by the hammer E".

After the cylinder or can-body has been operated upon by the hammer it is ready to be soldered, and is pushed along upon the mandrel to the soldering device by the next succeeding cans, which are moved along automatically by the mechanism above described.

The soldering device consists of the hopper G, suitably supported upon the arm G, attached to the bracket rising from the arm A", in which hopper pulverized resin'and solder are placed. The hopper is preferablyof the form shown and described in my patent, No. 359,962, dated March 22, 1887. The distributer is connected to the cam g upon the shaft 9 which latter derives its motion from the shaft A by means of the pulleys g g and suitable belt, operates the cam and causes the distributer to be reciprocated, thus sprinkling evenly the solder and resin upon the seam of the cans, which pass directly beneath the dischargeoutlet of said hopper. Suitably supported upon the standard G, rising from the arm A', is the soldering-iron G heated in any suitable way and capable of adjustment by means of the arm G" and adjusting device G but as this is a well-known expedient in can-making machines a further description will not be neces sary. The cancylinders are fedforward from beneath the solderinghopper by means of the chain G, passing over the pulleys G, operated from the shaft A by means of the pulleys g and g and belt 9". This belt G" is provided with projections similar to those above described upon the other belts,which projections engage the rear ends of the cams and force them forward. The can-bodies are now ready to receive the heads or tops and bottoms, the process of placing and soldering which is executed automatically in the following manner:

Secured upon the overhanging arm'H are the guides it, through one of which passes the spring-finger 7/, provided at its extreme end with a hook, 7L2. Hinged to the guides h are the jaws H, which when united form a sen 1icylinderof proper size to receive the can-body, and so constructed as to loosely hold the same, but to open and allow the same to drop when any additional weight is brought to bear thereon. This additional weight I prefer to apply in the following manner: Rising from the overhanging arm H is the casting H",

'formed with sockets h, which serve as guides for the vertical shaft H carrying the curved plunger H. Journaled upon this casting is the cam H which derives its motion by a belt from the shaft E, as shown in dotted lines, Fig. 1. if is a lever fulcrumed at k on the casting H, one end of said lever being pivotally connected with the finger h and its other end carrying a pin, it, working in the camh is another lever t'nlcrumed at one end to the casting H and at its other end pivoted to the link it, the other The rotation of the shaft 9 end of the link being attached to the shaft H. H is a pin attached to the lever h and working in the groove hof the cam These parts being so arranged and timed that as the plunger H descends upon the can-body and causes the jaws H to open, the finger h is thrown forward to grasp another can, and as the plunger ascends the said finger moves in the opposite direction and brings the next canbody into the jaws, which in the meantime have been brought back into their normal position by the springs h", provided and arranged i'or this purpose. As the can is released by the jaws H, it falls upon suitablyconstructed carriers carried by an endless chain arranged to travel at right angles to the direction in which the blanks travel during the operation above described. This chain and the mechanism pertaining thereto, constituting the conveycr for the completed bodies, is clearly illustrated upon Sheets 5, 6, and 7 of the drawings, to which special attention is now called.

I is a shaft journaled in suitable bearings (not shown) and carrying the drivewheel l and sprocket-wheel l, to which motion is imparted from any suitable source of power. Passing around this sprocket-wheel, and also around a similar wheel (not shown) at the other end of the track,is an endless chain made up of the links I, provided with eyes i and having lateral flanges t, which move in parallel horizontal guides t. These links are provided at either end with a lug, 1 between which lugs is secured by a hinged connection, as shown at F, the tilting can-carrier l. The sprocket-wheel l is provided with a peripheral channel or groove i, within which travel the rollers iupon the under side of thetilting can-carrier l. Thetrack, which extends upon a horizontal plane upon astraight linc,is suita- -bly supported upon supports i orin any other desirable way, and is formed of the bed i, in which the rollers t" areguided, and the parallel horizontal guides 2", in whichmove the lateral guides 011 the endless chain 1. This prevents the chain and cancarrier carried thereby from deviating from a straight line, and thus insures the can being presented to the soldering devices in the exact position desired.

The can-carriers lone of which is shown in section in Fig. 1l-are pivotally secured between lugs l"on the links l, by means of suitable screws, as shown at i, or by other hinged connection, so as to allow the carriers to tilt in a direction at right angles to the line of the endless chain, for a purpose which will hereinafter be more fully explained.

The tilting can-carrier l is provided with arms or extensions i and to the upper ends of these arms are pivotally attached the lower ends of the clamping-wings 1 provided upon their outer faces with the projections t". XVithin the hollow interior'of the upright portion of the casting l is arranged the hollow shaft 1*, within the lower end of which is journaled the roller i. The upper portion of the shaft 1 is of'less diameter than the lower portion, thus forming the shoulder t against which bears the spring 6, arranged within a suitable chamber above the shoulder, while within asuitable chamber within the foot of the shaft is arranged the spring i having a bearing against the upper face of the plate i. The arms 1' upon the wings L are connected to the casting K, secured to the base of the shaft 1 by means of the connecting-links K. W'ithin the lower part of the clamping portion of the can-holding chamber are arranged suitable projections or pins, 76, which, when the clam pin g-jaws are closed, bear against the surface of the can-body near its ends.

it is a concave piece of metal secured to the upper end of the adjustable shaft 1 and serves to slightly raise the can body when the clamping-jaws are opened, and thus allow the same to freely revolve during the process of soldering the end seams. 7

At the ends of the tilting can-carrier, and suitably journaled "within brackets or extensions K", are the wheels K, which, when in their normal or horizontal position, serve as brackets or shelves for the reception of the can tops and bottoms before the same are clamped in position upon the can-bodies.

From the foregoing description it will be clearly understood that when the tilting cancarrier is in its normal position upon the track the jaws will be closed, and that they will be opened only when the wheel t" reaches a depression in the track upon which it travels.

It will also be apparent that the normal position of the body of the tilting cancarrier is horizontal, and that it is adaptedto be tilted in either direction upon occasion of the wheels K reaching an. inclined guiding or tilting track-such as that shown at li in order that the end may be properly presented to the soldcring-irons.

When, therefore, the can carrier reaches the position beneath the deliveryclamps above. described, in connection with that portion of the machine in which the bodies are formed, the wheel '6 rests upon a depression, 90, in the track and the clamping -jaws are opened. Upon the forward movement of the carriage the wheel z" leaves the depression and thejaws are clamped around the can-body. An attendant upon each side of the conveyer places upon the wheels or shelves K the blanks for the tops and bottoms of the cans, the edges of which are turned slightly, so as to permit of their being placed in position over the ends of the can-bodies, which is done byattendants stationed at proper intervals along the sides of the conveyer. When the can carrier, in the course of the travel of the endless chain, reaches the point at which it is desired to distribute along the end seams the pulverized soldering material, the jaws are caused to open by reason of the wheels ireaehing a depression in the track, and the can within the chamber, through the mechanism above described in connection with the description of the carriage, is lifted from its contact with the pinsv7c and caused to revolve by reason of contact of A suitable the wheels K with the track K heating apparatus (not shown) is provided beneath the traveling can, in advance of the sol dering device, for heating the can in order to retain the solder upon the seam.

The solder is distributed upon the end seams of the can in the following manner: The soldering mechanism L, which is shown in crosssection in Fig. 10 of the drawings, consists of a series of hoppers, L. arranged upon suitablesu ortin -arms, L which are carriedb 8c pp in 7 y the endless chain L within the frame L*, placed in such a position as to cause the hoppers to pass directly above the cans as they revolve within the open chambers of their respective carriages. the bottoms of the hoppers are provided, which openings correspond relatively with the positions of the end seams of the cans to be soldered. The apertures in the bottoms of the hoppers are adapted to be opened and closed c by means of a suitable bar or plate passing through the hopper above the openings and provided with holes corresponding with the openings in the bottom of the hopper. This plate is reciprocated at the proper time by means of the pinions Z upon the post L (which it is connected with by suitable crank mechanism,) coming in contact with the raek-barl, secured upon the main frame of the device. Power is transmitted to the endless conveyer L by means of the shaft M and suitable train of gearing, as shown at M, 1W, M 850. After receiving the soldering material from the hoppers,-as above described, the can is in readiness for the final process of soldering, which will be readily understood by reference to Figs. 6, 7,8, and 9 of the drawings, in connection with the foregoing description of the general construction and operation of the end less chain and tilting can-carriers carried IIO thereby.

The soldering device proper consists of a se ries of hollow soldering-irons, N, suitably supported upon brackets upon a frame, N. This supporting-frame is in all respects similar to the supporting-frame used in connection with the soldering -hoppers above described, excepting that the rack-bar is dispensed with and adjustable arms or brackets for support ing the soldering-irons N are substituted in :20 their stead.

Asto the means for supplying air and gas to the soldering-irons, attention is directed to Fig. 12 of the drawings, in which Ihave shown upon an enlarged scale a verticalfsection of the apparatus used.

IN is the main central shaft, upon the upper end of which is placed the enlarged portion 1?; t

provided with the upper and lower chambers,

Secured to the [go P P, having openings p p.

Suitable openings within 85 P is an outer pipe of slightly greater diameter than the inner pipe, P. It closely fits at its ends about the pipe 1), and is provided at a point near its upper end with an inlet-pipe, p and has openings near its lower ends which communicate with the interior of the upper chamber, P. Gas is admitted to the lower chamber, P through the pipe P and is conveyed to the interior of the soldering-irons by means of the pipe R, and air is supplied from the chamber 1? by means of the pipes S, which are extended through the interior of the pipe R, as shown.

As the mechanism for operating the soldering devices is unimportant and forms no part of my invention, and, further, as it is in all respects similar to that used in connection with the solder-distributing mechanism, a detailed description ofthe same in this connection is not deemed necessary.

The tilting can-carrier having, upon its arrival beneath the first of the soldering devices, been properly tilted by means of the cam-track, suitably placed, as shown, so that the seam at one end of the can passes directly beneath the soldering'irons, the seam is thus soldered. In order to solder the seam at the other end of the can, the can-carrier is tilted in the opposite direction above the other soldering device by means of the cam-track suitably arranged upon the other side of the endless chain.

Various modifications in detail may be made without departing from the spirit of my invention.

Having thus fully described my invention and set forth its merits, what I claim to be new, and desire to secure by Letters Patent, 1s-
