CAN SOLDERING APPARATUS.

SPECIFICATION forming part of Letters Patent NO. 430,751, dated. June 24, 1890.

Application filed October 12, 1889. Serial No. 326,865. (No model.)

To aZZ whom it may concern.-

Be it known that I, DARWIN D. RANNEY, a citizen of the United-States, residing at Lewistown, in the county of Fulton and State of Illinois, have invented certain new and use ful Improvements in Can-Soldering Apparatus, of which the following is a specification.

My invent-ion relates to an apparatus for soldering the side seams of sheet-metal cans; and said apparatus comprises an endless belt or carrier driven by sprocket-wheels journaled in a suitable supporting-frame, receptacles for resin or flux loath and for a bath of molten solder, a wiper for wiping the seam after it has passed through the solder bath, and a coldair blast for cooling the cans after the seam has been wiped.

My invention consists in certain devices and combinations of devices in an apparatus of this general character, as hereinafter de scribed, and particularly pointed out in the claims.

In the accompanying drawings, Figures 1 and 1" show the apparatus in plan view, the ends broken away. Figs. 2 and 2" show the same parts in side elevation. Fig. 3 is acrosssction on line 3 8 of Fig. 1. Fig. a is a side elevation of animproved form of Wiper-wheel, and Fig. 5 is a transverse section thereof.

Referring to the drawings, A represents the supporting frame-work, upon whilFare carried adjustable standards B, the latter supporting a track 0, which will be adapted to the form of the can to be operated upon.-

D E represent shafts rotatably mounted at the respective ends of the track, and these shafts carry sprocket-Wheels F G 011 either side of the track. Over said sprocket-Wheels link-belts II are carrmd, said belts being connected by rods I, which will be placed ,far enough apart to receive between them the cairbody, and at such height above the track as to engage the end of the can, whereby when the belts are rotated the cans will be moved along the track.

At one point in the track, as indicated at J, I provide a receptacle to contain melted resin or a flux bath, through which the seam of the can is moved. At the end of this flux-receptacle I provide a second receptacle, as indicated at K, to contain molten solder, into which the can is dipped as it passes along. This solder bath will preferably be kept highly heated, and this is done by suitable heating appliances, which in this instance comprise the burners L, adapted to burn a vapor of gas and air, supplied by the branches on n from the pipes M N: After the solder has been applied the cans are presented to a wiperavheel O, which is of peculiar construction, and is particularly illustrated in Figs. 4 and 5. Said wheel comprises a central hub P, having a number of disks 1) of diiferent diameters secured toward the re spective ends thereof, and between them is provided a central space. which may be filled with felt or other fibrous material. This wheel is rotatably mounted on a shaft Q, which is carried in sliding bearings R in the ways S. The bearings B may be adjusted along the way by means of the screws T. The shaft Q may be driven bya belt from a pulley U on the shaft V. The presser-bar W, which is preferably in the form of a flat metal strip, is carried by a bracket in such position that its free end engages the top of the can as the latter passes over the wiper wheel, whereby the can is held upon thewheel with sufficient force to insure the cleaning of the joint. The cans are delivered to the trough Y at the end of the machine.

In operation the cans are taken in that stage Where they are bent to form, with the edges overlapped and with the ends crimped on and placed in the track at the end of the machine. The belt being put in motion the cans are passed along, first throughthe flux bath, next through the solder,over the wiperwheel, and then, if desired, the joint may be cooled by means of a coldair blast supplied from the head Z, having nozzles .2, after which they are delivered from the machine. The continued use of the wiper-wheel rapidly wears the fibrous material thereof, and the construction which is herein shown enables this wearing to be compensated for by the removal of the outer disks 1) as fast as the Wiping material wears away, and the periphcan-bodies, flux and solder receptacles in said track, a wiper-wheel adapted to remove the surplus solder from the joint, a spring-arm adapted to bear on the cans to hold them in contact with the wiper-Wheel, and means for delivering a blast of cold air to the seam after it has been wiped, substantially as described.

2. In an apparatus for soldering the side seams of sheet-metal cans, having a track along which the cans are moved, and suitable flux and solder bath receptacles, a wiperwheel constructed of a series of graduated disks and a core of fibrous material and a spring-arm adapted to hold the can in con-- tact with the wipenwheel, substantially as described.
