CAN-SOLDRING MACHINE.

SPECIFICATION forming part of Letters Patent No. 391,171, dated October 16, 1888.`

Application filed May 2l, IESS. Serial No. 274.473. (No model.)

To all whom it may concern:

Be it known that we, CHARLEs B.l MoDoN ALD, a citizen of the United States, and WAL- TER VAGNER, a citizen of Switzerland, residing at Chicago, in the county ot' Cook and State of Illinois, have invented certain new and useful Improvements in Can-Soldering Machines, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part hereof, and in which- Figure 1 shows our improved can soldering machine in side elevation, as seen from the front or working side thereof. Fig. 2 shows on an enlarged scale, on the line x x of Fig. 1, a transverse View through the soldering-pots and the positions of a can in each soldering pot. Fig. 3 shows a transverse view of the machine on a plane, y y, of Fig. l, the position of the canearricr with its chucks open in the lower and closed in the upper position, and the end of the chuck-spindle 2in its groovem. Fig. 4 shows an enlarged view of a link and its can-carrier in vertical end elevation, taken on the plane x .t of Fig. 6, as seen from the forward end of said Fig. (i. Fig. 5 is a rear view of an entire chain-link and its rollers, with a eancarrier and its lever and springs. Fig. 6 shows in plan an entire chain-link and its attached rollers and all that partof the canscarrier below the planeyyof Fig. 4. Fig. 7 shows the lever t" and its attached parts in plan vlew.

Like letters of reference refer to like parts.

The object of our invention is to construct a canvsoldering machine in which both ends of the can are soldered to the eanbody bya singie insertion of can into the machine, and to prevent the solder from flowing to one side or lumping` byeansing the can to assume a vertical position immediately after being soldered; and to attain said ends we construct our improved can-soldering machine substantially as follows, namely:

XVe mount an endless chain or belt, a, upon two drums or wheels, b b', which preferably, and as here shown, run in a vertical plane. The shafts of said wheels are carried on bars c, which connect two upright standards, d, at each end of the machine. A similar standard is placed in the middle of the machine and is connected to said end standards by means of conneetingbars. Upon one side of the chain each link has a pair of lugs or arms, e, between which and on pinsfis hinged acan carrier, g, which is free to revolve in a plane around and at right angles to the axes ofthe pinsf, which enter into the ends of the short shaft g', forming a part of the can-carrier g. Each chainlink has at one end a pair of lugs or arms, a2, and at its opposite end a single central lug, a', which passes between the two lugs a2 of the next preceding or succeeding link, as plainly shown in Fig.6,and which are there connected by means of a pin, a3, passing through said lugs, so as to permit said joint to work freely when the chain is passing around said drums, and ou each of the ends of said pin or pins c, outside of the lugs a2, are mounted rollers a4 c5, the former a plain drum and the latter pro vided with a flange at both its ends.

Each joint ofthe endless chain is made and provided with rollers, as just described, and is carried upon tracks or chain-carriers a al, attached to the standards d. Said tracks a c7 are placed, respectively, above and beneath the rollers c a?, to guide and keep the links ofthe chain moving in a true line.

The weight ofthe can-carrier g and its load tends to twist each link of the chain from a horizontal toward a vertical plane around the pulley c5, and therefore the track a is above the roller a4 and the track al under the roller a5. The flanges on each side of the rollers c5 will cause them and all attached parts to move in a true vertical plane with the track a7. There is also a hood or semicircular covering, b, around the outer half oi' the wheels b b to hold the links and their pulleys a* w" in place while they pass from the tracks over and around the outer halves of said drums.

The tendency of the cancarrier g is to fall into a horizontal position at right angles to that shown iu Fig. 3 as it hangs and turns freely on the pinsf; but the desired normal position of the axis of the cans is vertical to the chain-carriers or tracks or the chain on said tracks. Therefore, in order to keep the carrier vertical or inclined at such times and places as desired, suitable cams, tracks, and guides-are employed, as hereinafter shown.

The opening or receiving end of the machine is from the points h to h if, the points h h h2 indicating a cam which serves to open the 2 estivi i chucks to discharge the finished can, and also short rise, h', at the outer end of which it forms an approximately continuous circle from. the center until it comes to a point vertically below the center ofthe wheel-shaft,after which it continues its surface as a tangent to said circle until it reaches the point h2, where it gradually rounds off upward at about therelative distance from the wheel-shaft, as shown in Fig. 1, or at a point which is back far enough to permit the chucks t' to close upon the can ends before the lower roller, ix, on the cam j gets to the receding curve j, which forms a part of the cam j.

The chucks 13 are opened by means of said cam at the point h', which there depresses the roller'iand springithus separatingthechueks t', where they discharge the cans from the machine and where they may fall into any suitable conductor or hopper and through it be led off to any suitable receptacle.

After the chucks t' reach the position vertically under the tangent part of said cam they are horizontal and ready to receive cans which are there fed into the machine as they pass along under said cam,which is made long, so as to allow plenty of time to feed the cansinto it.

Upon each of the shafts of the wheels b and b is mounted asemicircular guide, m, in which the wheel-shaft turns. Said cam is held in place by means of a hub which reaches back to and is attached to the hub of the cam h hh, also mounted loosely on the same shaft in the same manner and held from turning by means of a connecting-bar, h3, connected to some part of the frame, as to the cam or bar j, (shown in Fig. 1,) or by means of a bar, h, connected to the frame d, or by any similar device.

At about the middle of the receding part of the can1j-thatis, in the middle of the cam jz-begins the lower solder-trough, k, which is made long enough to permit each can to make several complete revolutions in it from the time it dips into until it leaves its fluid solder. Said trough k is held on brackets 7a2 and arranged so that the surface of the solder may be nicely adjusted to the can. In this case the bed-plate 7a4 of the trough k is shown held by a screw-bolt, la, through the bracket 7a2, and when necessary wedges (not shown) may be driven under the bedplate to adjust the trough 7c, and on said bracket, or attached to the frame of the machine, is held a cam, js, both ends of which have cams bent so as to be about parallel to the ends 7'2 of the cams j', which they overlap. Said cam ja, as also the cam jt, is so placedas to cause the upper roller, ix, to fall upon it when the caucarrier g is released from the lower cam, j ji. Said roller by its friction causes its can to revolve, as shown by the arrows, with the motion of the chain, so as to give the edge dipping into the solder sufficient time to become thoroughly soldered during the time that the can -is pass ing through said soldering-trough.

At the fart-her, end of the solder-pot k the cam j3 is formed just as it is at the near end, and thereby as the can advances it again rises toward the perpendicular, and there the lower roller, z', is caught by a receding portion,j2, on a cam, j, made in every way in this respect as the cam j' at the front of the soldering-pot, except that it points in the opposite direction, from which it is again raised and held in the perpendicular position, and through this construction the can is again caused Ato revolve in the opposite direction, as shown by the arrows.

After the lower ends of the cans have been thus completed they pass on and over the wheel b', and thus become inverted,where by an arrangement of cams j,constructed, placed, and operating precisely as said parts already described in passing the cans through the trough k, the now lower edges of the cans pass into and through the trough 7c and are turned on the spindles i', in the direction indicated by the arrows, by'means of the cam j, which is constructed and arranged precisely as the cam ja, the cans becoming through it erected as they leave the solder pot or trough k. cans are received and held on a cam,j, and passed along to the discharging end of the machine through mechanism constructed and operating as already described.

The opposed revolving plates or chucks, fi, are carried on spindles i in the same axial line, provided with rollers dx, so placed as to leave a free outer end, i2, which passes into the groove m in the semicircular guide m atl the tangential poi nt,when the roller X begins to leave the straightcamsjjand passes around the wheels b b', by means of which the cans are held erect and guided in their passage from the lower to the upper cams, and vice versa.

On the spindle or spindles i', which are uppermost when on the lower side of the machine, there is secured a grooved collar, i3, in the groove of which enter the points of pins is, passed through the `opposite ends of the forked lever a Said arrangement permits a free revolution of the spindle t, while at the same time the chucks t' may be separated by The roo A' IIO vIIS

means of said lever, which is fulcrnmed at i5 lugs i0 and pass freely through i9 on the lever it.

Thewheels b b have sprockets b2, which fit into the links a, and thereby secure uniform and positive motion to all the parts.

.ullA .A A

The mechanism may be actuated from the shaft of either of said wheels, to which suitable power may be applied. One method of doing this is illustrated in Fig. 3, Where a pulley, if, is attached to one of said drum-shafts and is driven by a belt, b", from a cone-pulley, as shown, and of well known construction. The said cone-pulley has a pinion, n, securely attached to it., which operates a gear-wheel, n', turning loosely on a stud attached to the frame of the machine, and attached to said wheel n and turning with it is a pinion, n2, which drives a wheel, n, which runs loosely on the hub ofthe said cone-pulley o, and has attached to it a belt or chain pulley, a, from which the belt b5 drives the pulley b", which turns the shaft and drum b, which gives the desired motion to the endess chain a. Each of said wheels b b is also provided with a groove which receives the inner flange of the rollers c5 as it passes around them.

The advantages obtained in the herein described and claimed construction are these, namely: There being but a single insertion or handling of the can to solder both ends, there is but half the liability to imperfect chucking that there is where the cans have to be taken out, inverted, and rechucked. r)There is, therefore, less than half' the manual labor, and, second, when a can end has passed through the solder bath it is liable to have lumps of solder, &e., on it, which will prevent proper chucking, and thereby cause the can to Wabble, and such motion will canse imperfect soldering of the other joint, and, finally, when a can has been soldered and is then held in a position with its axis either inclined or parallel to the plane of the horizon, the solder before cooling is sure to flow more or less upon the underside of the can and cause an unsightly excess and a weakening of the upper part of thejoint, all of which we considerl serious objections and which we overcome perfecfly in our construction.
