Title: Improvements relating to dynamo electric generating machinery particularly applicable for use in electric arc welding
IPC: H02K23/40
Filed: 1929-11-06
Abstract: 343,052. Dynamo-electric machines. QUASI-ARC CO., Ltd. and MUSTO, R. J., 15, Grosvenor Gardens, London. Nov. 6, 1929,.No. 33801. [Class 35.] Yokes and carcases ; exciting.-A continuouscurrent generator for electric arc welding purposes is arranged to have a drooping characteristic by placing slightly in front of each main pole, in the direction of rotation of the armature, an auxiliary pole which carries a series winding acting in opposition to the main shunt winding carried by the main poles. To ensure a substantially constant shunt field the winding T carried by the main poles A<1>, B<1>, A<2>, B<2>, is excited from two auxiliary brushes l, k one of which is placed to connect with conductors situated between a main pole B<2> and its auxiliary pole C<2> and the other to connect with conductors slightly on the leading side of the central plane of the pole B<2> so that they embrace a nearly constant flux. One auxiliary brush b only need be used when the second connection is made with a main brush. A compounding series winding r is provided on the main poles. To control the load current when electrodes of different gauges are used the series winding on the auxiliary poles a<1>, b<1>, a<2>, b<2> is tapped in sections s<1>, s<2>, s<3>, s<4>, and a switch f used to control the number of sections in circuit. Alternatively a variable inductive diverter is placed across the series winding. The yoke Y, Fig. 3, is made of small cross section and plates x, y of small cross section are used to connect the polepieces to the yoke so that the magnetic circuit of the machine is saturated at low armature voltages.

[Class 103 (i)] Brake-operating mechanism comprises a direct braking branch, a clutch operated power braking branch, the clutch and the direct braking branch being operated from a common pedal &c. through a floating lever and the transmission from the clutch to the brake comprising a winding mechanism and a pull-amplifying unit connected to a member to which also the direct braking branch is connected. A floating lever 3 pivoted at 6 on the pedal 2 is connected at 5 by a link 7 to a member 20 which may be the pressure lever of a hydraulic transmission system connected to the brakes or an arm on the cross-shaft of a mechanical transmission system. The lever 3 is also connected by link 9 to the operating lever 8 of a clutch the driving member 14 of which may be secured to the driving shaft adjacent the gear casing 10 in the case of a motor vehicle. The driven member of the clutch carries a winding drum 15 to which is attached a cable 16 connected through a lever 18 and cable 17 to the arm 20. The arrangement may be such that upon depression of the-pedal, pressure is applied directly to the brakes through the connection 7 before the clutch is engaged through the connection 9 to render the power application effective. Alternatively the clutch may be first engaged. The lever 18 serves to amplify the pull of the clutch on the brakes; it may be replaced by a hydraulic amplifying device comprising one or more small pistons connected to the cable 16 and arranged to force liquid into a cylinder containing a larger piston connected to the cable 17. The diameter of the drum 15 may be smaller than the average diameter of the clutch faces to give a mechanical advantage as between the clutch and the cable. The clutch may be of the radially expanding shoe type the operation of which is assisted by centrifugal force or it may comprise a belt and pulley. The pedal may have a stop 40 for engagement with the lever 3 to ensure the operation of either the direct or the power branch in the event of failure of the other.
