Abstract: 436,818. Supply systems for welding; momentary-contact switches; snap-action switches. SCIAKY, D., 13, Rue Charles Fourier, Paris. Aug. 22, 1934, No. 24237. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 25, 1935.] [Class 38 (iv)] [See also Group XXXVII] A transformer used in spot welding has its secondary winding 2, Fig. 1, connected to welding electrodes 3 and its primary winding 1 connected to a current source 14, the transformer having a large leakage inductance and welding being produced by interrupting the primary current to obtain a high secondary voltage. The primary circuit is made through a resistance 13 by a contact arm 9 carrying a contact blade 8, the resistance 13 being cut out in steps and the primary circuit then broken. The transformer ratio may be varied by a tapping switch arrangement 1<1>, 1<11>. The pivoted contact arm 9 is provided with a pin 91, Fig. 2, at its lower end and is moved in the direction of the arrow f by a spring 19 when the pin 9 is released by a stop 201. Depression of the pedal 16 causes the spring 19 to be wound up by the ratchet wheel 18 under the action of the rack connected to rod 17, the arm 9 being released for operation by the stop 201 when the pedal 16 approaches the end of its movement and cam 23 causes rod 25 and plate 20 to move downwards against the action of spring 22. Movement of the contact blade 8 over the contacts is then controlled by a stop 20<11> with the sloping face of which the pin 91 contacts after leaving the stop 201, the arm 9 being permitted to turn under the action of the spring 19 as the plate 20 is moved downwards. According to the Specification as open to inspection under Sect. 91, welding may be produced by sudden closure of the primary circuit by moving the contact arm in the opposite direction or a charged condenser, which may be charged from an alternating current circuit through a rectifier arrangement, may be allowed to discharge through the primary circuit. This subject-matter does not appear in the Specification as accepted.
