ELECTRlC MOTOR.
. SPECIFICATION forming part of Letters Iatent No. 547,323, dated October 1, 1895.
Application filed January 4, 1 895.
To all whom it may concern.-
Beit known that we, ADDISON E. Boocs, of Allegheny, and FREMONTJ. OLEAVER, of Beltzhoover, county of Allegheny, State of Pennsylvania, have invented a new and Improved Electric Motor, of which the following is a f ul], clear, and exact description.
The object of our invention is to construct an electric motor especially adapted for direct connection with the machine to be driven or with line-shafts or car-axles, or for use in connection with gearing or pulleys and belts for diminishing or increasing the speed.
The invention consists in the particular construction and combination of parts, as hereinafter fully described, and pointed out in the claim.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both views.
Figure 1 is a side sectional elevation taken on line 1 l in Fig. 2, and Fig. 2 is a front elevation.
In the present case we shall describe our improved motor as applied to car-driving. The car-axle A is provided with car-wheels B B of the usual description, except the adaptation of the car-wheel B to receive the movable parts of the motor. In the present case the field-magnet C of the motor is formed integrally with the car-wheel B; but it may with equal advantagebe attached to the carwheel by means of bolts. consists of a cylindrical ring with inwardlyprojecting pole-pieces a, upon which are placed magnetizing-coils D. The field-magnet may be Wound according to any of the well-known systems, so as to use the motor as a shunt or a series machine.
Upon the car-axle A is placed a metallic sleeve E,'which is loosely fitted to the axle, so as to permit the axle to revolve therein. Upon the metallic sleeve E is placed a sleeve F, and upon the sleeve F is mounted the boss G of the armature II. On the boss G are placed annular soft-iron plates 1), which are clamped between insulating plates 0. The iron plates of insulating material are perforated to permit of passing the winding of the armature H through them, the armature be- The field-magnet Serial No. 533,828. (No model.)
ing by preference constructed according to the Gramme system.
On the boss G is mounted a wheel I, provided with an insulating rim (1, on which are mounted commutator-bars e. To each commutator-bar e are attached the terminals of adjacent coils in the usual manner.
To the side of the annular part of the fieldmagnet C is attached a ring f, of insulating 6o material, to the face of which are secured two metallic rings g g, and in the insulating-ring f are inserted studs h h, carrying springpressed commutator-brushes it, which bear upon the commutator-bars e. The stud 7b is connected with the ring g and the stud h is connected with the ring g. The terminals of the field-magnet are also connected with the rings g g, and the said rings receive current through contact-springs jj, connected with the circuit-wires according to any of the wellknown systems.
On the boss G of the armature is clamped and keyed a lever J, the ends of which extend in opposite directions and rest upon spiral springs K K, supported by cross-bars Z Z belonging to thetruck which carries the motor. Springs K K are placed above the ends of the lever J, and a bolt at each end of the lever passes through the springs, the lever, and through the cross-bar to the cartruck. It will thus be seen that each end of the lever J is held between buffer-springs, which allow the armature to turn slightly against a yielding pressure, thus preventing shocks to the armature when the motor is started or stopped. While the armature remains stationary, the field-magnet may revolve and cause the car-wheel to be propelled forward. The sleeve F and parts carried thereby is prevented from slipping on the axle A by a split-collar L. In the sleeves E F in the boss of the armature and in the lever J is formed an opening Z for receiving a lubricant, which is retained by the cover m, 9 5 arranged to shut tightly over the opening Z.
It is obvious that in some applications it would be preferable to hold the field-magnet and allow the armature to revolve. The carwheel is provided with a concave rim n with radial passages 0 leading therefrom for receiving used oil discharged by centrifugal upon the boss of the armature, and having an insulated rim upon which are placed commutator bars, an insulated ring secured to the pole pieces of the field magnet, inwardly extending studs secured to the insulated ring and carrying brushes, and metallic rings secured to the face of the insulated ring and connected with the said studs, substantially as described.
