MACHINERY FOR THE MANUFACTURE OF CANS.

SPECZFICATION forming part of Letters Patent No. 305,514, dated September 23, 188%.

Application filed November 3, L883.

To all whom iv may concern.-

Be it known that I, WILLIAM SPENCER Dore, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machinery for the Manufacture of Cans, of which the following is a specification.

My invention relates to improvements in machinery for the manufacture of cans, and it has reference, primarily, to means for receiving and holding the bodies of cans, and pre senting the said bodies severally, individually, and alternately in position for the reception of their respective tops and bottoms. The apparatus is provided with a rotary shaft provided with lateral arms, each of which arms carries clamping means adapted to embrace and hold the body of a can; and the said lateral arms are so arranged that they shall be capable of being controlled by automatic mechanism in such manner that a series of can-bodies held and controlled by the said series of arms shall be each automatically, alternately, and successively placed in position, so that one shall receive a top and the othera bottom, and then by the automatic revolution of the main shaft and the turning of the lateral shafts holding the clamping means the said can-bodies shall respectively be brought into position to receive their tops or bottoms.

can-body, and the process is continued, continuously producing cans with tops and hot toms. I employ means for exerting pressure on plates or pushers which are operated by levers or other equivalent means for the purpose of holding the can-bodies in proper position in the holders while the tops and bottoms are being applied. Iprovide also means for The tops and bottoms are fed into recesses or apertures (No morlcld closing in or squeezing the outer rim or edge of the grooves or sunken heads of the tops or bot toms in position to be seamed by soldering. The device is by preference supported on two separate tables connected by a bracket or brackets; but it may be with equal facility mountedona single table similarly constructed. The jaws which form the clamping means are by preference arranged in guides or ways formed or applied in the main table or tables.

These guides are controlled and operated by levers, also controlled and operated by levers actuated by an eccentric or crank supported on and revolving with a driving shaft or shafts. Upon the main shaft or shafts is mounted a disk or plate provided with four or more raley affixed to or carried by an arm supported by a shaft or axis mounted in bearings formed in the main framing,and upon which is mounted the main gear and cam wheel, hereinafter described. To the upper end of this shaft or axis is affixed a bevel-gear, on which is formed or applied a cam or course adapted to opcrate the short arm of a lever, the long arm of which is connected by a peculiarly-formed socket or bearing to the main shaft, and its long arm is pivoted to a standard or bracket formed on or affixed to the main framing. In the revolution of the cam or coursesupported on or operating the short arm of the lifting-lever by means of a socket or bearing, motion is communicated to a pair of compound levers, one end of each of which is mounted in a bearing connected to the main framing, while to its opposite end is pivoted a link, the opposite end of which is pivoted to a plate or pusher adapted to cause the body or partiallyformed can to beheld in position while its top or bottom is respectively being squeezed or closed by means of the sliding jaws or clamps. The bottoms are fed in at one end of the machine, and the tops at the opposite end thereof. The lateral or radialarms are by preference supported and carried by an inverted hollow cup provided with a series of radial bearings, each provided with radial or other suitable flanges. The bearings carried by the inverted hollow cup may be cast therewith and cored orbored out so as to form bearings IOC . anism, and this pulley is mounted on a shaft bodies; or the said bearings may be connected thereto by bolts or rivets or by any other suitable means. Motion is by preference communicated to the apparatus by means of a driving-pulley, to which motion is also communicated by a strap or band or other driving mechcarried by a bracket supported on the main framing, on which is also mounted a bevelgear gearing with a larger bevelgear, on which is mounted a cam, which in its revolution is adapted to come -into position to operate a lifting-lever pivoted at one end to afixed bearing or bracket, and'also by means of. a truss, cup-and-ball, or other suitable bearing is pivoted to the main shaft in such manner as to allow of the free rotary motion of the main shaft therein, while at the same time the said shaft is free to be lifted or lowered in a verti-. cal direction, so as to raise and lower the mechanism holding and controlling the posi tion and operation of the can-holders, and consequently of the can-bodies held thereby. On-

, clamps or squeczersare being applied to close the rimor edge of the bottom or top. The apparatus is provided with duplicate series of levers, clutches, and eccentrics, which are all timed and controlled by the revolution of the main gear and cam-wheel.

The accompanying drawings form part of this specification, and illustrate what I consider the best means of carrying out my invention.

Figure l is a plan view of my improved apparatus. Fig. 2 is a plan view of the main plate, partlyin section. Fig. 3 is afront view, partly in section, of the machine. Figs. 4 to 19 are detailed views.

Similar letters of reference are employed to indicate corresponding parts in all the figures.

A represents the main table, which, in the arrangement shown in the drawings, is formed in two halves, A A, connected together by a bracket or connecting-piece, A each half or section being supported upon a framing, A Upon the upper side of the main table A, I mount or affixvpairsof brackets or supports A* A adapted to carry a transverse beam, A to which are bolted or attached vertical supports or brackets A and A, the support or bracket A being provided with a bearing, a, for the reception and support of one end of the shaft B, the opposite end of which is supported with capability of revolution in a bear- -ing, a,'carried by the transverse beam A Upon the'end of the shaft B is mounted orv aftixeda driving-pulley, B, which, by means of a strap, band, or other suitable operating means, receives motion from a steam-engine or other source of power. Upon the shaft B is mounted a pinion or gear-wheel, b, which takes-into and drives a pinion or gear-wheel, O, which is mounted on a short vertical shaft,

0, passing through a bearing, a formed in or applied to the transverse beam A To the lower end .of the shaft 0, beneath the transverse beam A is applied a crank arm or lever, O, the forward end of which is provided with a vertical extension or frictionpulley, 0, adapted at each revolution of the pinion or gear-wheel O to enter into one or other of the radial slots (1, Figs. 9 and 10, formed in a disk or plate, D, affixed on the main vertical shaft D. The main vertical shaft D is provided with a hollow cup or casting, E, provided with a series of radial bearings, E, each provided with a series of radial or other suitable flanges, Ff, adapted to give greater strength and rigidity to the bearing E in each of which is supported a revolving lateral arm,

F, which, at its outer extremity, is provided with a clamping device, F, hereinafter more fully'described, adapted to embrace and hold acam-body, G, or other similar device. Upon the inner ends of each of the revolving lateral 0 supported in a hollow bearing, aflformed on or affixed to theconnecting-piece A The hollow bearing a is provided with a groove or recess, a, Fig. 2, adapted to receive a feather or other equivalent connecting means formed on or affixed to the hub e. The main vertical shaft D revolves freely in the hub 6 but at its lower end is provided with a collar or shoulder, 01, adapted to support and retain the hub e and. its gear or pinion e correctly in relation to the gear or pinion e, in what ever position the vertical shaft D may be held I for the time being.

The clamps or holders F are by preference formed of a light or paneled angular frame, the part f of which is provided with a boss or trunnion, f, adapted to be connected with the outer ends of the revolving radial arms F. Extending from the part f is a light rectangular or paneled portion, j", on the outer end of which are formed bosses or bearings, f adapted to receive the endsv of a shaft or the axis upon which a clamping-plate, f is pivoted either directly or by means of arms f, as shown more clearly by Fig.'18. The part f of the frame is also provided with bosses or bearings, f adapted to receive the ends of a shaft or the axis of another clamping-plate, similar to the one previously described, The'arms f 5 of the clamping-plates f* in the arrangement shown are provided with squared faces, f f", Figs. 16 and 18, against which a fiat bearing-spring, f operates for the purpose of holding the clampingwhen desired, and when turned down into the position indicated by Figs. 1 and 16 to hold the can-body firmly while the same is being traversed so as to receive its top and bottom.

Upon the upper side of the pinion or gearwheel is formed or applied a cam-surface, 0, Figs. 1 and 6, which, at every revolution of the pinion or gear 0, is timed to come under the end of a lifting lever, H, which is pivoted at its rear end to the bracket or standard A", while its forward end is by preferencev formed with an anti-friction wheel, h, adapted to roll on the upper surface of the pinion or gear-wheel G, and be raised at the proper time by the cam or projection O". The lifting-1e ver 11 is pivoted, as shown, by Figs. 1 and 2,

to a truss bearing, I, (shown separately at Figs.

11, 12, and 13,) which is provided with grooves or recesses 1', adapted to receive correspondingly-formed annular rings or projections d formed on the upper end of the shaft D, the object of the said truss bearing being to allow of the free revolution of the shaft D, while at the same time its vertical p osition is controlled by the'lever H. 3

1 On the upper ends of the truss bearing I are formed lugs or projections t" 1', adapted to form bearings for a pair of compound levers, J J, one end of each of which is respectively pivoted to the brackets or standards A A while their opposite endsj are connected to the upper ends of links or rods j", the lower ends of which are pivoted to plates or pushers K, for the purpose of exerting'pressure 011 the bodies or partially-formed cans G, while the clamps or squeezers L are operated to close the rim or edge of the bottom or top for the time being applied.

Each section A of the table A is formed with a countersunk recess or aperture, A of a proper form and configuration to receive the grooves or countersunk heads of the tops and bottoms for the time being manufactured.

In the drawings I have shown an oblong square can in the course of manufacture. I can, however, with facility adapt my invention to the manufacture of other forms of cans.

The clamps or squeezers L for each section A of the table A are operated to and fro, when desired, by means of a series of compound levers, M M, pivoted to a bearing-piece, M, to which an up-and-down motion is communicated by means of a link, M", connected to a pin, m, carried by a disk or eccentric, M mounted on the end of a shaft, M", working in bearings A A carried by the framing A.

Uponthe outer end of each of the shafts h is mounted a loose pulley, m, to which motionis communicated by a strap, band, or other suitable mechanism.

M are clutches, also mounted on the shafts M, and adapted to be thrown into position to connectthe loose pulley on with the shaft M at such times as it is desired to force forward the clamps or squeezers L to close on a top andbottom. The forcing inward of the clamps or squeezers L is effected by the rotation of the shaft M, and the motion imparted thereby by means of the intermediate mechanism (above described) to the compound mechanism M M. The clutches M are each, in the arrangement shown,actuated by a bellcrank. M, one arm of which is connected to a rod or lever, M pivoted at its upper end to a lever, M affixed on the end of a rockshaft, M", on which is formed or attached an extension or hit, M arranged in position to be operated at the. desired time by a nose or projection, 0", formed on or affixed to the C? that the said nose or projection 0 by the intermediate mechanism above described, shall cause the clamps or squeezers L to close upon the tops and bottoms, respectively, imme diately the ends of the can-bodies are inserted into their grooves or sunken heads. The clutches M are disengaged at the desired time from the driving-pulleys m by means of studs or projections m,whieh in the revolution of the clutches come into contact with fixed inclined surfaces M. adapted to cause the clutches M to be drawn out of contact with the driving-pulleys m.

The levers J J are so arranged and constructed that they shall lift the pushers or plates K a sufficient distance after each bottom or top has been inserted not only to allow of the free lifting-of the clamping devices F, but also to allow of a space being left between the top of the bodies being operated upon and the under side of the plates or pushers K.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-- 1.
