OF LEE, ENGLAND.-

MACHINE FOR F usmc SIDE SEAMS OF METAL CANS, 800.

SPECIFICATION forming part Of Letters Patent NO. 671,546, dated April 9, 1901.

Application filed October 22, 1900. Serial No. 331932. (No model.)

To all whom it may concern:

Be it known that we, JULEs GERSANT, a citizen of the French Republic, residing at 1 Netherford road, Larkhall Rise, in the county of Surrey, and ARCHIBALD GEORGE BUTTI- FAN'I, a subject of the Queen of Great Britain and Ireland, residing at 32 Southbrook road, Lee, in the county of Kent, England, have invented new and useful Improvements in Machines for Fusing the Side Seams of Metal Cans and Like Receptacles, of which the following is a specification.

Our invention relates to improvements in machines for fusing the side seams of metal cans and like receptacles by the process of fusing together within the seams the coating with which the metal from which the cans and receptacles are made, the machines being designed more especially for use in the manufacture of cans and the like made from tinned iron sheet.

We attain our object by the mechanism illustrated in the accompanying drawings, in which- T Figure 1 is a side view of one half of the machine; Fig. 2, a part-sectional side view of the other half of the machine. Figs. 3 and 4 are respectively plans of the portions shown by Figs. 1 and 2. Fig. 5 is a front view of a detail.

Supported on suitable standards a, attached to a base-plate or other surface 17, we provide a table a, at a convenient height above the surface b. Below the table 0 is an air-chamber d, in communication with a blower of proper capacity. At the bottom of the airchamber dis a stuffing-box 6, through which passes the vertical shaft f, the lower end of which is supported in the foot-step g. To the vertical shaft f is bolted the revoluble platform h, having below it the air-pipe 2', which can rotate at the same time as the table h in the stuffing box j, formed in the table 0. Above the rotatable platform It is a gaschamber' 70, into which gas enters through holes l in the gas-pipe m, passing through the stu fling-box n. At the lower end of the pipe l is a plug 0, stepped in a recess in the upper end of the shaft f. Outside the gas-chamber 7.5 is the air-gallery p, communicating with the air-pipe i and chamber d by holes q. At intervals around the periphery of the table h are the saddle-shaped mandrels a", each having an open top covered with a steel plate 3', on which rests the seam of the tin t to be op erated on.

Provision is made for taking tins of more than one length, L-sectioned vertical guides it slidable on the horizontal guides i), which themselves are slidable on pins 10, so as to allow of two of more than one diameter being held on the mandrel. These guides u and '0 are retainablein their required position by set-screws 10. Below the steel plate 3 is a burner to, perforated along its upper side. Gas is supplied to the burner from the gaschamber 76 by the pipe 11 having the regulating-tap z, and air is admitted by the pipe A, communicating with the airgallery p, the pipe A being furnished with a regulatingtap B.

The vertical shaft f is rotated through a portion of a complete revolution equal to its division by the number of man drels r by the following means: On the shaft f is the ratchetwheel 0, with which engages the pawl D, carried by the link E, the arm F of which is pivoted to one end of the reciprocating rod G, furnished with the shoulder H. To the rod G is attached one end of a cord or equivalent J, which passes over the pulley K and is provided with a weight L, which tends to draw the rod G away from the shaft f and so to pull the shaft f and table h around to the extent of one tooth of the ratchet-wheel G. The rod G is pushed toward the shaft f for the purpose of taking up another tooth of the ratchet-wheel C by the following means: Pivoted at M to a plate N, attached to one of the supports a,is a lever O, the upper end of which is pivoted at P to one end of the connectingrod Q, the other end of which is pivoted to the crank R on the shaft S, carrying the spurwheel T. The spur-wheel '1 is operated by the pinion U, free to slide with one part of a clutch V on the driving-shaft W, which carries the other part X of the clutch and also the fast pulley Y and the loose one Z. A

X into engagement with one another, and the part of the clutch marked V is hinged at b to the shaft 0, free to turn in end bearings (1, carried by brackets 6, attached to the table 0. v j the roller f, on which the mandrels 0" rest when in position for the tin to be operated on by the pressing-roller to be hereinafter mentioned. As the mandrels r are saddle ones, a bridge-plate f is provided to rest on the roller f when the mandrel ris in position, the roller f keeping each mandrel at the right height above the table a as it comes into position.

which is kept normally at right angles to the shaft 0 by a spring 71. The lever h has a hooked end j to receive a pin 70, one of which is provided on each mandrel r, so as to arrest the individual mandrels as they come into position to have the seam rolled down. There is also an arm I standing out fromthe shaft;

0 and having its outer end attached to one;

. normal position during the intervals between} the mandrels r reaching it, which position is one of inclination in the opposite direction tolj that occupied when it is arresting the move-. ment of a mandrel by catching a pin it in itsi hookj.

The seam of the can is rolled and pressed. by the roller 71, carried at one end of a lever; 0, pivoted at n to one end of the reciprocatfl ing harp, a recess in which bar receives the; other end of lever 0, the roller being kept; down by the upward action of a spring q be-' tween the lever end and the bottom ofthe recess. The reciprocating bar 19 is free. to

. run in the guides 1", attached to the bed a,

so as to move the roller m in and out of the tin can being operated on and press down'the seam. The reciprocating bar 19 is moved to and fro by the vibrating lever s, pivoted at t to the base-plate b. The vibrating lever s is linked to an adjustable piece it, provided on the reciprocating bar 1), by which piece u the throw or travel of the bar 10' can be altered to adapt the machine to boxes of various lengths. The vibrating lever s is moved to and fro by a bolt 1), passed through a slotted arm 11) of the spur-wheel T. The slotted arm to and the slot at in the vibrating lever 8 permit of the before-mentioned adjustment of the travel of the bar 19 by moving the adjustable piece it to the required extent along the bar 10. v

The following provision is made for releas-l ing a mandrel when the tin carried by ithasi had its seam pressed by the roller m and its place is to be taken by the immediately succeeding mandrel bearing another tin. A rod y is free to run to and fro in suitable guides: and is provided with upstanding pins 2. At

one end of the rod y is a beak A, pivoted One of the brackets e carries. also,

thereto at B, and behind'this beak is a spring C, pressing against the back of beak A. Behind the hook j of the lever m is a projection D-,and on the adjustable piece to and in the same plane as the pinsz is a pin which alternately strikes the pins .2. When the piece u'is on its backward journey, its pin strikes one of the pins 2, so as to cause the beak A to pull on the projection D and draw the hookj clear of the pin It and so allow the mandrel to pass on to the extent the table h is moved by one tooth of the ratchet-wheel C, whereupon the lever m is pulled upward by the spring m, to be pushed back again when To the shaft 0 is hinged at g a lever h,

the pin k of the succeeding mandrel 7' comes in contact with it. The forward journey of the piece 11, in the meantime strikesthe other of the pins z and pushes the beak A over the projection D, the spring 0 yielding sufficiently to allow it (the beak A) to pass and force it into position to again pull on the projection D on the backward journey of the reciprocating bar 1).

Any suitable means may be provided to prevent or lessen concussion when the table h is moved around step by step. Such means may consist of pins E, hanging fromthe platform 71,, which pins, as the platform moves around, press back one end of a lever F, pivoted to a bracket G, attached to the table 0. This lever F has attached to it one end of a spiral springH, the other end of which is attached to a bracket J, fastened to the table 0. When the movement of the platform h'has caused the pin It of a mandrel to pushbac'k the lever 71, the pin E willgo out of contact into the lever F and pass on, leaving the lever F to be drawn "back by the spring H,-the outer end of the lever F striking against the buffer K, provided at one end of aboltL, carried'in abracket M, attached tothe table 0.

The operation of the machine is as follows: Assuming, first, that theburners x areall in action; second, that there is a can on each mandrel 'r, with its fluxed seam resting on the plate 8, and, third, that the weight L has drawn around the table it to the extent of half a tooth of the ratchet wheel 0, then the lever m will be drawn over by the spring m and the partsv and w of the clutch disengaged and the gearing out of action. Assuming, also, that the various parts have been so assembled during construction that under the above conditions, fourth, the bar 1) is at the end of its back stroke; fifth, that the lower end of the lever 0 is also at the end of its return stroke and out of contact with the shoulders H, and, sixth, that the beak A is on the forward side of the lever m, then when the weight L completes the movement of the table it to the full extent of one of the teeth of the ratchetwheel O the pin 70 of one of the mandrels 1" will push back the lever m and revolve shaft 0 suflicie-ntly to cause the two parts 11 and w of the clutch to engage with IIO one another and set the gear in motion. The bar p will now be pushed forward, so that the roller n will pass into the can and press down the seam which rests on the plate 3. The lever 0 will also have pushed forward the rod G, so that the pawl takes up a position to pull around the table h to the extent of one tooth of the ratchet-wheel 0 when contact of the lower end of the lever 0 is removed from the shoulderH of the rod G. On the return stroke of the bar 1?, drawing the roller 01, out of the tin, the pin on the adjustable piece to will come in contact with that one of the pins a" on the bar g, which will draw rearward the beak A and push backward the lever m, whereupon the leverm will resume its nominal position by the action of the spring m and put the clutch'u and it; out of engagement, and the lower end of the lever 0, having also reached the end of the rear movement, the weight L will draw the rod G backward and cause the ratchet-wheel G to advance the tabe of circular or other than saddle cross-section, so that the tin if instead of being quite outside it, with the exterior of the seam resting on the plate 3, may be slid over it, in order that the mandrel is inside the tin and the plate sin contact with the interior of the sea m instead of with its exterior. This is essential in the case of decorated tins. In some cases also we prefer to have the air-chamber (1 above the platform It instead of below the table 0. Provision may also be made for more than one reciprocating bar 10 and its accessories on one machine.

It is to be clearly understood that the tins operated upon by the roller n are so operated on after the seams have been heated sufficiently to fuse the coatings within the seam, and not till then.
