Title: A machine for electric welding, soldering or the like
IPC: B23K11/00
Filed: 1926-05-25
Abstract: 252,411. Languepin, J. E. J. May 23, 1925, [Convention date]. Hollow-ware.-In an electric welding, soldering, or brazing machine, particularly for joining wires or strips to tubular members, such as zinc cells, a shaft, driven through a one-revolution clutch, carries cams for operating respectively an electrode-actuating lever through an adjustable tension spring, wire, &c. feed levers, severing mechanism, a switch, and a combined work rest and ejector. For welding a wire 80 to a tube 72, the tube is placed over an electrode 73 connected to one secondary terminal of a transformer 27 and is supported on a stud 70, Fig. 7, and rest 71 on a lever 69, which is mounted on a pivot 67 carried by an adjustable member 68 and having an adjustable lever 65 engaging a cam 64 on a shaft 8. The shaft 8 is driven by belt gear from a shaft 2, being connected to its driving pulley 7 through a one-revolution clutch controlled by a pedal 10. If the cam is shaped to provide a sufficient interval between the end of one cycle of operations and the beginning of the next to allow a new blank to be inserted, the pedal may be held down continuously and the clutch thus kept permanently in engagement. The wire 80 is drawn from a reel through a bath 78 containing a pickling substance or a solder or brazing paste, through straightening rolls, over a guide roll 81 and roll 44 on a guide 42 secured to the framing. The wire is gripped between a slidable bar 41, Fig. 4, and a lever 38 pivoted thereto and is fed forward by a cam 30 through a spring-retracted lever 32 and link 36. Another cam on the shaft 8 then operates a lever 14, which is loosely mounted on a pin 16 and connected by an adjustable spring 17 to a member 18 keyed on the pin, so as to lower a spring- returned lever 20 and thus apply the electrode 25 to the work. At the same time an insulating tongue on a further cam pushes a blade spring against a second adjustable blade spring to close the primary of the transformer and thus effect the weld. The electrode 25 is secured to an angularly adjustable member 23 by a pivoted screwadjusted member 22 so that it can be adjusted for wear. The wire is next severed between cutters 54, 55, Fig. 5, of which the cutter 55 is carried by a lever 52 connected by a link 51 to a cam-operated lever 47. The lever 59 is subsequently operated to eject the finished tube.
