JOI-IN SOLTER, OF BALTIMORE, MARYLAD, ASSIGNOR OF ONE-HALF TO GEORGE L. KREBS, OF SAME PLACE.
CAN-SOLDERING MACHIN E.
SPECIFICATION forming part of Letters Patent No. 411,070, dated September 17, 1889.
Application filed May 27, 1889. Serial No. 312,262. (No model.)
To all whom t may concern:
Be it known that I, JOHN SOLTER, of Baltimore, in the State of Maryland, have invented a new and useful Improvement in Can-Soldering Machines; and I do hereby declare that the followingV is a full, clear, and exact description of the same. l
My invention is an improvementl in cansoldering machinery; and it consists in the combination, with the two vertical can-carriers having can holding and releasing devices and soldering devices, of aconveyer between said carriers, by which the can is conveyed from one carrier to the other, so that first one head is soldered and then the other.
The invention also includes a special form of can-seat, which permits the accurate feeding of the solder to the head-seam and the relative arrangement of name-tube and soldertube; also, the details of construction form a part of my invention.
In the drawings, Figure lis a plan sectional view of the two carriers, with conveying devices for the cans in plan. Fig. 2 is a side elevation of one of the carriers, partlyin section. Fig. 3 is a front view of the same, and Fig. 4 is a detail viewvof a can-seat.
In the drawings the two carriers are shown at A B, consisting of vertical wheels, revoluble intermittingly upon horizontal supports d h.
The can-seats a b are radially arranged, and comprise the seats proper, which support the cans and the rings or plates `2, beneath which the iiame plays against the head-seam. The ring is held by arms 3, projecting from a sleeve 4, which is secured to the wheel by a bracket 5. The sleeve affords a bearing for the spindle 6 of the can-seat, which spindle is held by a collar 7 and has upon its other end a beveled 'pinion c. Each pinion meshes with a beveled master-wheel O on `a sleeve 9, which at its rear end has a gear D, meshing with a pinion d on the shaft 10. This shaft is driven from any suitable source of power through the pulley 11. By this master-Wheel and the pinions the can-seats are geared,'as in patent to Boyden, No. 237,238. For moving the table step by step I employ substantially the same mechanism as that shown in my patent, No. 397,758, consisting of the ratchet E on the sleeve of the wheel, which ratchet is driven by a loop and pawl F G, operated by a stud I-I on the face of the gearwheel.
The can-holders consist of spring-pins I, working through the ends of curved brackets t. These brackets extend from the front edges of the rings, so that the other side of the seat is entirely free for the Jfeeding and discharge of the cans. Each of the spring-pins has a button on its end, and its inner bearing end is formed so that it will not indent or damage the can-head when in contact therewith.
The feed-conveyer K consists of an inclined trough extending from the rear side of the first machine to a point immediately in front of the right-hand can-seat, the upcurved end of the trough being arranged so that the can will be in line with the can-seat, which at this can and press the same to its seat and hold it,l to be carried to the heating and soldering devices. Then this can leaves the can-rest at the end of the conveyer, another can moves by gravity into place ready for the next canseat.
The can is soldered at station a; by automatic devices similar to those shown in my patent aforesaid, consisting, briefly, of the dame-tube f, the solder-tube s, the drum, and ratchet-feeding device r, operated from a cam q by a rod o. The solder is drawn from a reel e. The partiallysoldered can is discharged at station Y, diametri'cally opposite the feeding-station, and consequently also horizontal. The discharge is effected by the retraction of the spring-pin at a point z alittle above the discharge-station by a cam- IOO plate z. The can drops from its seat by its own weight into a conveyer K', also consisting of an inclined trough. The spring-pin is held retracted bythe cam during its passage by the horizontal station. This trough conveys the can to the second carrier, which in construction and operation is exactly similar to the one above described. The can is fed to the right-hand horizont-al canseat of this carrier, and thus the can is reversed in position with respect to the seat, the head, which was engaged bythe holder in the first carrier, being now Within the seat and in position to be acted upon by the soldering devices of the second carrier, which are arranged in the same relative position to the second carrier as those iirst named to the iirst carrier. From this feed-station the can is carried upward to the soldering-station, and then downward to the final discharge-station XV, whence it may be conveyed to any point desired.
The carriers,with their driving mechanism, are preferably arranged reversely to each other.
Any suitable cooling-tubes are used.
The second carrier may be driven from the shaft 10 by pinions 12 13, COuntershaft 14, and pinions 15 1() 17, as shown by dotted lines, Fig. 1; but any other manner of driving the carrier-s may be employed.
In order to allow the accurate feeding of the solder to the seam, and at the same time provide a ring for retaining the heat at the seam, and also to allow the use of a stationary solder-tube extending near the seam, I forni the ring with a depressed portion where the solder is fed, the upper surface of the ring here being in the same plane or a little below the seam, While the rest of the ring is slightly above. The solder-tube extends close to the seam, as in Fig. 4t, and said tube is not struck by the ring as it passes by. The surface of this part of the ring might be curved slightly. The iiame-tube f is arranged opposite the solder-tube and below the ring.
I do not wish to coniine myself to the pre cise conveyer shown.
I claim- 1. In combination,the two vertical can-can riers with separa-te can holding and releasing devices foreach can, and a conveyer between them for transferring the cans from one cai'- rier to the other and inverting them in relation to their can-seats, substantially as described.
2. In combination, a series of can-seats on a movable support with can -holders and means for releasing the cans when they are approximately in a horizontal position, asecond series of can-seats with automatic cangripping devices, and a conveyer for transferring the cans in approximately a horizontal position from one series of seats to the other and inverting them in relation to the canseats, substantially as described.
In combination, the two vertical wheels, the conveyer between them arranged to re ceive the canin a horizontal position from one wheel and convey and hold it in linewith the can-seats of the other wheel, and cause it to be inverted in relation thereto, and separate automat-ic gripping and releasing dcvices for each of the cans, substantially as described.
l. In combination, a vertical table in which a feed-station and a discharge-station are arranged approximately opposite, a second vertical table having a feed-station positioned in relation thereto similar to that of the first feed'station to the first Wheel, and a conveyer between the discharge station of the Iirst wheel and the feed station in the second Wheel for transferring the can in an inverted position to the second table, substantially described.
5. In a can-seat, the ring having a depressed portion to allow feeding of solder to the seam, substantially as described.
6. In combination, the can-scat, the ring, the flame-tube below said ring, andthe soldertube arranged opposite and above the ring, said ring having a depressed portion to allow the feeding of solder, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JOI IN SOL'IER.
