CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 295,662, dated March 25, 1884.

Application filed January 15, 1884. (No model.)

.useful Improvements in (Jan-Soldering Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in can-soldering machines in which floats or end seams of-round cans are soldered; and the objects of my improvements are, first, to either solder one or both the end seams at the same time; second, to either solder the can from the cap or solder in the head of the can when filled with the goods; fourth, to provide means that will protect the side seam from being unsoldered when the heads are being soldered in; fifth, to support the mechanism on a central vertical shaft and from a suspended hanger.

. I attain these objects by the following mechanism, illust-rated in the accompanying drawings, in which V Figure 1 is aside view of the entire machine, part of which is in section; Fig. 2, atop view of the hanger and gear-wheels; Figs. 3 to 8,

, enlarged detail views of the mechanism that imparts the intermittent motion to the rotary table; Figs. 9 and 10, details of the arm and segment shaped piece that raise the canclamping disks; Fig. 11, a top view of the upper plate of the rotary table; Figs. 12 to 20, detail views of can-holders; Fig. 21, side view of the machine when adjusted for capping the filled cans; Figs. 22 and 23, detail views of capholding device, and Figs. 24: and 25 views of the cans.

Similar letters refer to similar parts throughout the different views.

The hanger A is suspended from above and provided with a yoke, through which the lineshaft B passes. On the latter is a pinion, a,

clutched thereto by means of the sliding clutch b, provided with the lever 12, by which the machine is operated.

Through the perpendicular sleeve A of the hanger A passes the vertical shaft 0, the lower end resting in the bearing f on the floor.

. To the shaft 0 are attachedthe gear-wheel a,

which engages with the pinion a on the lineshaft B; the crank c, which vibrates the pendulum D; the external master gear-wheel, E, which rotates the can-holder (I when 'in an inclined position; the internal master gearwheel, F, which rotates the can holder d when perpendicular; the cam e, which operates the solder-valve mechanism, and the rotary table G is supported and rotates freely thereon.

The table G consists of an upper and lower plate, 9 and 9, connected rigidly together by means of the sleeve h. Attached. to the periphery of the lower plate, 9, are yokes t, in which the hubs 13 are swiveled, and which are held or adjusted to the desired angle to engage the pinion k with either of, the masterwheels E or Fby means of the segment-shaped slot Z onone arm of. the yoke i, and a clampingscrew, f, which passes through the slot Z and into the hub 03. In the hub t" runs the spindle i, to which is attached the can-holder d and the pinion 7a The upper plate, g, is provided with an upward cylindrical projection, 9 in which are notches g ratchet-teeth u, and arms m, projecting therefro1n,which have upper and lower bearings, m and m, through which the spindle i passes.

To the spindle i is attached a clamping plate or disk, n, which holdsthe can Hfirmly in the holder d by means of the spring a, i which bears down on a flanged collar, a, attached to the spindle tfby means of a setscrew, it", which allows the collar n to be adjusted to suit the heights of the different cans. The spindle t and its attachment are lifted by the flanges n of the collar 11?, which comes in contact with the segmentshaped piece 0 on the outer end of the arm 0 as the table-G rotates, the latter stopping with the can-holder d opposite the ,center of the arm 0, thereby holding the clamp or disk 02 up, allowing the operator to conveniently place or remove the cans; The intermittent movement is imparted to the table G by means of the crank g on the shaft 0, provided with a roller, 0, which comes in contact with the adjustable lugs or projections 19 and p onthe pendulum D, alternately. The pendulum D is pivoted to the downward-projecting rod g at one end, and provided at the opposite end with the hollow boss 1', containing therein a spring, and the pin 1", which engages with the ratchet teeth a on the plate 9. As the crank c rotates, the roller 0 comes in contact with the lug 0, thereby moving the pendulum D to one side, which then remains stationary until the crank 0 makes part of its circuit, or until the roller 0 comes in contact with the .lug p, which will move the pendulum D'in the opposite direction to which it was first moved. The pin a" in the meantime engaging with a ratchet-tooth, u, on the plate 9, the table G is rotated one-twelfth of its circumference, and then remains stationary until the roller 0 again comes in contact with the lug 10. By the aforesaid mechanism the table G is rapidly moved after the can is soldered, thereby freeing the can from the heat quickly, at the same time starting and stopping the table gradually. The table G is held rigid while the cans are being soldered, placed, or removed by the pin t in the sleeve t, engaging in the notches g on the plate 9, and relieved therefrom by the lever m, connected to the pin it at one end, and at the opposite end pivoted to the rod q, the lever being lifted by the upward-projecting incline s on the crank 0, coming in contact with the downward-projecting incline s on the lever m at each rotation of the shaft 0.

To the downward-projecting rod q at the lower end is attached aprojecting arm, 9, provided with a brake-shoe, g, which bears down on the cylindrical projection 011 the plateg, which prevents the table G from jumping forward when in motion, the whole being suspended from the cross-arm A, which is attached to the hanger A by means of the setscrews 6 e.

The can-holders consist of cylindrical rings (Z, arms (2, and notched plates d. The plates at are placed on the arms d, and are held to their .places by the notches Z, fitting over the upward projections d of arms (1, to prevent the scorching or discoloring of the can ends and the cap-crease. The outer ends of the arms (1 have upward projections (1 to which is attached the ring (1, allowing the end of the can which rests on the arms d to project below the ring (1 sufficient only to melt the solder therein, thereby protecting the upper part of the can from the heat and effectually preventing the melting or unsoldering of the side seam. The holders d are changed to suit the different-sized cans by means of auxiliary rings is, the inner diameter of the same suiting the size of the cans to be soldered, while the outer diameter neatly fits in the ring d. The projecting shoulder on ring It prevents the same from entering the ring (1 too far. To

each set of auxiliary rings are corresponding bottom plates, d. By this convenient arrangement any sized can smaller than the cylindrical ring d can be soldered, and in case of larger cans special holders are provided.

The arm I is attached to the cross-arm A by the rod q, provided with a clamping-nut, and has an inward and outward adjustment by means of a vertical slot, 0, through which the rod q passes. To the downward projection of the arm I is attached a receptacle, L, containing molten solder, which is ejected on the ends of the cans by means of a valve formed by the rod 1, (see Fig. 21,) which has a cone-shaped end resting in a counter cone in the nipple 2, which forms the seat of the valve, and is operated by means of the bell-crank 3, reciprocating rod 4, cam e, and draw-spring 6. 1

The machine is operated by one boy, who stands opposite the disk-lifting arm 0, placing and removing the cans, which are soldered in the following manner: When soldering both ends of the can without removing the same from the machine, the can is constructed as shown in Fig. 24, one end having the flange projecting over the can-body, and the other end placed insidethe same. Before or while placing the cans on the machine, a segment of wire-solder is placed in the can on the end which has the flange projecting over the can-body, the same end being placed in the ring (I. As the cans are carried around by the table G, they come in contact with the flame from the hydrocarbon-burners R, (which are placed opposite to where the can-holders stop, the number of burners depending on the size of the cans and the speed at which the machine is run-ordinarily about four,) which fuses the solder placed in the can, and which is distributed around the seam by the rotation of the same. The opposite end of the can having the end placed inside the body, (see Fig. 24,) forms a V-shaped groove, in which the molten solder is ejected from the receptacle L by means of the cam e and the intervening mechanism, the heat being applied to the cans from burners placed as those above stated before and while the molten solder is ejected.

thereon.

Either of the aforesaid methods may be used independent of the other, one end of the can being soldered in at a time, the moltensolder device being used if both end seams of the cans are to be soldered from the outside,the cans being constructed with both ends placed inside. (See Fig. 26.) To solder both ends from the inside, the arm I and its attachments are dispensed with or removed, the can being soldered by the former method, as above stated, when using the segment of wire-solder, the can being constructed as shown in Fig. 25.

WVhen capping or soldering in the heads of filled cans, the machine is adjusted as shown in Fig. 21, with the can-holder d placed perpendicular, and the arms m on plate 9 removed and substituted by the arms 3 provided with the hollow hubs y, springs as, and pin 00, which holds the head or cap down in its place, the pin azhaving a cone-shaped end which fits the vent-hole of the cap, and which contains an escape-port, 0 to allow the vapor to escape from the filled cans when heated,

the soldering being done by ejecting molten solder in the cap-crease from the molten-solder receptacle L, as when soldering the ends of cans, as before stated. The cans may be capped, or the entire head soldered in, the lat-, ter being the most desirable, as the cans are more conveniently filled.

The machine having all its mechanism sup ported on the vertical shaft 0, and suspended from the hanger A, dispenses with a table or frame, thereby making all the adjustments readily accessible, simplifying the machine, and occupying less space. y

Having described myinvention,what I claim as new, and wish to secure by Letters Patent, 1s

1. In a can-soldering machine, the combination of the rotating vertical shaft 0, the rotary table G,rotati'ngthereon freely, mechanism to impart tothe table G an intermittent movement, and the hanger A, supporting the said intermittent mechanism, whereby an undersupporting table, or frame is dispensed with.

2. The combination of the rotary vertical shaft 0, the table G,supportcd thereon and rotating intermittently around the rotating shaft 0, and mechanism centrally supported that will move, stop, and hold the table G, whereby free access may be had to all parts of the machine. v
