Filed: 1922-09-26
Abstract: 200,469. Dayton Engineering Laboratories Co., (Assignees of Ruthenburg, L. R.). July 6, 1922, [Convention date]. Coils and conductors; commutators; insulation; apparatus for making and assembling.-Consists in a construction of continuous-current armature and commutator adapted for assembly by machinery wherein the commutator is moved on to the shaft and assembled directly with the winding leads which are formed by the ends of the armature bars themselves. The slotted core 35, Fig. 3, is supported on concentric tubes 48, 49 on a base 44 which receives the shaft at 46 and the previously bent hairpin conductors 31, 32 are slipped into the slots, two conductors occupying each slot. The ends of the limbs 31, 32 are rounded to facilitate easy insertion of open-seamed insulating slot linings of 8 section, Fig. 2, from the other end of the slots over the conductors in situ. The conductors are then bent towards each other so that their ends 50, 51, Fig. 11, project in rigid pairs in radial planes ready to enter the spaces in the commutator risers when the assembled commutator 53 is pressed axially along the shaft. The commutator, Fig. 9, consists of segments 56 each of which is flanked on both sides by L-shaped risers 58 separated by the usual insulation 57. The commutator hub is so angularly placed on the shaft that the conductor ends 50, 51 are opposite the openings between the pairs of risers and it is held on the shaft frictionally. A series of split radial tools 61, Figs. 11 and 12, may be placed over the ends 50, 51 to hold them in spaced radial position and radial pressure on the tools may be used to bring the conductor ends to the correct radial position in place of bending the ends by a separate previous operation. The ends of the risers are then bent and clamped on to the conductor ends and the commutator is immersed in molten solder to a point above the inner surface of the risers 58. Before the solder has set, a tool 65, Fig. 16, is clamped on each pair of risers to squeeze out excess solder, and the whole is allowed to cool. The armature is then mounted between centres and the rounded ends of the conductors which project beyond the front face of the risers are removed by means of a circular saw. Finally, solder deposited on the commutator during the dipping is removed. In place of being bent in, as shown in Fig. 16, the risers may be bent over the top of the upper conductors 51, as shown in Fig. 17.

Abstract: 747,196. Variable-speed and reversing epicyclic gearing. OFFICE TECHNIQUE INTERNATIONAL O. T. 1. Sept. 22, 1953 [Sept. 26, 1952; Oct. 24, 1952], No. 26140/53. Class 80(2) One sun wheel 10 is connected to the driven shaft 11 and the other sun wheel 7 is geared to the driving shaft 1, which latter is also geared to a hydraulic pump 32 of constant capacity and to a hydraulic sliding-vane pump 44 whose capacity can be varied by turning its casing 46 and which is arranged in series with the pump 32, while the planet carrier 6 is connected to a hydraulic motor 9 which is of constant capacity and which is arranged in parallel with the pump 32, the combined capacities of motor 9 and pump 32 being equal to or less than the maximum capacity of pump 44. 'At maximum capacity of pump 44, pump 32 absorbs a constant quantity of the output and the remainder drives the motor 9 so that shaft 11 is driven reversely at maximum speed. As the capacity of pump 44 is progressively reduced, the reverse speed of shaft 11 gradually reduces to zero and then the shaft is driven forwardly at increasing speed. When the output of pump 44 is absorbed wholly by pump 32, motor 9 will be stationary and will thereafter be driven reversely by pump 32. The casing 46 of pump 44 is turned automatically according to the speed of shaft 1 by a governor 21 acting through linkage 22, 23, 55, 47. Manual control may be affected by moving a pin 58 engaged in a slot 54 in link 55.
