WILLIAM RUBIN, OF SOUTH OMAHA, NEBRASKA.

ROUND-CAN-FLOATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 743,567, dated November 10, 1903.

Application filed January 30,1902. Serial No. 91,930. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM RUBIN, a citizen of the United States, residing at South Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Round-Can-Floating Machines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a simple, inexpensive, and efficient mechanism for soldering the heads and bottoms of tin or sheet-metal cans to the bodies thereof.

It is a further object of my invention to provide means for adjusting the said mechanism Figure 1 is a side elevation partly in sec tion. Fig. 2 is a sectional elevation on the line X X of Fig. 1. Fig. 3 is a perspective view of the turn-over device at the end of the upper can-track. Fig. 4. is adetail end view of part of the solder-feeding mechanism. Fig. 5 is a side view of the same, and Fig. 6 is a sectional view of the lower solder-pot and the adjustable support for the sheaves for the can-rotating cable. Fig. 7 represents an enlarged perspective view of the solder-pots and can-positioning guide with surrounding parts broken away.

In the construction of the machine I employ a number of pairs of suitable standards 1 1 1 1, one of each pair on each side of the machine, which standards at their lower ends are secured upon suitable base-blocks 2 and tightened hold the sections of pipe in position and keep the standards properly spaced.

, Between the end pair of standards 1 and 1 are journaled in suitable bearings the shafts 7and 8, carrying the sprocket-wheels 9 and 10.

The bearing'boxes for shaft 8 are placed in slotted openings 11 in standards 1 and have adjusting-screws 12 for tightening an endless chain 13, which passes around the sprockets 9 and 10.

The chain 13 is provided at regular inter vals with flat fingers 14, as shown in Figs. 1 and 2 and best shown in Fig. 3, secured on edge and projectinglaterally beyond the side of the chain.

Except while passing around thesprockets 9 and 10 the chain 13 rests on a track formed of longitudinal angle-irons 15 15, which are supported by transverse angle-irons 16 16,

around the curved track 18. After passing between the first pair of standards 1 this track is slightly inclined laterally, so that the cans are tipped over to bring the edge of the bottom downward and in this position are rolled through the solder-pot 19. This pot is supported alongside of and below the chain-tracks 15 by the longitudinal bars 20, secured to the standards 1 l, andby transverse bars 21. While rolling through the solder-pot the cans are held down into thesolder and given an additional rolling movement bya continuous cable 22, which is held in position against the cans by small idler-sheaves 23, which are adjustably secured to standards 24, projecting upwardly from the bars 20. In suitable bearings on the standards 1 1 are the shafts 25 and 26, carrying sheaves 27 and 28 for cable 22. The shaft 26 is driven through the medium of a pulley 29 thereon and a belt 30, connecting said pulley with a second pulley 31 on a shaft 32, carrying a sprocket 33, connected by a chain 34:, extending around a sprocket 35 on the shaft 7.

0n shaft 25 an arm 36 is pivoted, which carries on its opposite end a small idler-sheave 37, which rests on the cable 22, keeping the same taut.

The cans after rolling through the pot 19 pass over a guide 38, which is inclined laterally and further turns the can so that it rests on its bottom. In this position the cans are slid along a track one side of which is formed of one of the angle-irons 15 of the chain track and the other side of which consists of an angle-iron 39, as shown in Figs. 1 and 3. The bottom of this can-track is formed of bars and 41 of rounded strap-iron, which are secured to and supported by cross-pieces 42, which in turn are secured to the chain track irons 15 and the side piece 39. The cross-pieces 42 have a number of holes 43 therein, so that the side bar 39 and bar 41 may be set in varying positions thereon in order to widen the track to accommodate various sizes of cans.

At the end of the upper can-track, which is shown in Fig. 3, one of the bars 40 extends beyond the end of the other bar 41 and is slightlycurved upward. When the cans are pushed off this track by the fingers 14 of the chain, they are supported and raised on one side by this bar 40, so that they are further turned a full quarter-way round and drop over on theirsidesinto the flaring end of the chute 44 and roll down the same, following the line of travel of the chain 13 around the sprocket 9. At the lower end of this chute 44 the cans are'further slightly turned to cause the edges of their tops to roll through a second solder-pot 45, as shown in Figs. 2 and 6, the said tops being open heads of wellknown form. \tVhile passing through this pot the cans are rolled faster and held in position as before bya cable 22, passing around adjustable idlers 23, mounted in standards 24*, sheaves 27 and 28*, and tightening-idler 37 of substantially the same construction and arrangement as the corresponding parts hereinbefore described, the cable 22 passing around sheaves on shafts 32 and 32, as shown in Fig. 1. After passing the pot the cans are further turned on their top ends by the inclined sides of a laterally-inclined guide 38 and in this position slide along a track as before until reaching the sprocket. 10, where the track ends and the cans are dumped upon a conveyer or into suitable receptacles.

It will be observed that the upper and lower solder-pots and guides are exact duplicates of each other, and I have illustrated the upper one in perspective, so that the construction of both may be fully comprehended.

The lower track from the solder-pot 45 to the end of said track is covered, as shown in Fig. 1, by an elongated box 66, which has openings 67 in its ends large enough to admit of the passage of the cans and drivingchain and to permit of the insertion in said box of the tracks therefor. Inside the box 66 and below the can-trackis a pipe 68,which has on its upper side a number of small nipples or jets 69, which extend up close to the track. While the cans are passing along the track steam or water under pressure from any suitable source is forced into the pipe 68 and through the jets 69. As the open ends or heads of the cans are down ward, this steam or water will enter the cans, and also on the steam or water striking the top of the box between the cans 66 it will drop down on top of the cans, so that the cans will be washed thoroughly inside and out in passing through the box 66. A drain-pipe 70 at one end of the said box serves to carry off the water or steam.

The construction of the solder- pots 19 and 45 is substantially similar, and the latter is shown in Fig. 6, which illustration will serve for the pot 19 also. It will be seen that the pot has a hollow space 46 below for the introduction of a suitable heating medium for keeping the solder melted." Above this space is the pot proper for containing the solder, comprising a space 47, which extends into a projection 48 on the rear side of the pot. This space 47 is provided with a cover 49, on which the cans rest and which has a projecting rib 50 for holding the cans down, so that their edges will be sure to dip into the melted solder. Solder in the form of ribbon or wire is supplied to the pot 47 through a pipe 51, as follows, as best shown in Fig. 2: On a shaft 32 is an eccentric 52, which is connected by a twisted bar 53 to a link 54, which is adjustably secured to the pawl-arm 55 on shaft 56. This shaft extends longitudinally of the machine and is supported in suitable bearings carried by the standards 1 and 1". Adjacent to the pawl-arm 55 on shaft 56 is a ratchet 57, with which a pawl 57*, pivoted to the arm 55, engages, so that the movement of the said eccentric will cause an intermittent rotation of the said shaft, the extent of which will be controlled by the adjustment of link 54 on pawl-arm 55.

Centrally above the solder- pots 19 and 45 on the shaft 56 are wheels or disks 58 58, having in their peripheral surface grooves or depressions 59. (See Figs. 4 and 5.) WVithin these grooves run smaller disks 60' 60 on arms 61 61", which are pivoted on the sections of the pipe 4 between the standards. Springs 62 62 are attached to the arms and to loose collars 63 63 on the shaft 56 and hold the disks 60 60 yieldingly in contact with the disks 58 58 A wire or ribbon of solder 51 is introduced between these disks 58 and 60, Figs. 1 and 2, and passes down the pipe 51 to the solder-pot 45, being intermittently fed by the action of the ratchetand eccentric mechanism, as described.

Pipe 51 serves to conduct solder-wire 51 to solder-pot 19, the wire being actuated by the is melted and fills the spaces 47 of the pots to a sufficient depth. Power is applied to the pulley on shaft 7, and the various chains, belts, sprockets, sheaves, cables, &c., are driven, as described. The cans to be soldered are placed in the feed-chute and roll down-the same until they reach the track 18, when they are engaged by the fingers 14 on the chain 13 and carried upward and rolled through the solder-pot 19, so that one edge of the bottom of the can dips into the solder contained therein. This rolling is assisted by the cable 22, which, it will be observed, travels in the same direction as the cans and at greater speed. On passing over the pan 38 the inclined sides of the same turn the cans over, so that they rest on their bottom ends and in this position are slid along the upper track until they reach the end thereof, when they drop into the chute it and roll down the same. In dropping into thischute the cans are further turned a quarter-way round, so that the edges of the top of the can which have not been soldered are toward the front side of the machine. In this position they are rolled through the pct 45 and this remaining or top edge is soldered. On passing the guide 38 the cans are further turned a quarter-way round, so that they reston their heads or open ends and in this position are slid along the lowertrack and through box 66, being washed inside and out while therein, as described.

By means of the described construction I am enabled to solder both heads of the can and to thoroughly wash it inside and out Without the necessity of handling the can during any part of both operations, and while I have specificallydesoribed the construction and operation of the various parts I desire it to be understood that I do not confine myself to the exact constructions and arrangement, but hold that many minor changes and variations therein might be made without departing from the spirit and scope of my invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a can-soldering machine the combination with a traveling endless chain designed to convey cans, and a solder-pot through which said chain moves, of an endless cable suitably mounted to bear upon a can while nation with a traveling endless carrier and a solder-pot over which said carrier moves, of an endless cable traveling in the direction of the travel of said carrier and at a greater speed than the same, and suitably mounted to bear upon a can carried over said solderpot on said carrier for rotating the can during its movement through the solder-pot, substantially as described.
