UNITED STATES PATENT OFFICE.
HENRY M. BYLLESBY, OF ST; PAUL, MINNESOTA.
ELECTRIC-RAILWAY MOTOR.
SPECIFICATION forming part of Letters Patent No. 467,969, dated February 2, 1892.
Application filed June 16, 1891. Serial No. 396,526. (No model.)
To all whom it may concern Be it known that I, HENRY M. BYLLES'BY, of St. Paul, Ramsey county, Minnesota, have invented certain Improvements in Electric- Railway Motors, of which the following is a specification.
My invention relates to improvements in street-railway motors, its object being to provide a motor by means of which the wheels of the car are rotated at a much lower speed than that of the motor without employing reducing-gears; and to this end it consistsin employing an improved type of motor in which the fields and armature are concentric with each otherand independently rotatable about their common axis, the armature being connected to one of the car-axles and the fields to the other by such intermediate gears or other connections that the opposite rotations of the armature and fields impart motion to the car-axles in the same direction.
My invention further consists in an improved construction whereby the motor connected to one car-axle may be geared to the other car-axle by two intermediate gears only and impart motion in the same direction to both axles. The construction of the motor itself I do not seek to cover by this application, the same being embodied in another application of even date herewith, Serial No. 395,466.
My invention further consists in the construction and combination hereinafter described, and particularly pointed out in the claims.
In the accompanying drawings, forming part of this specification, Figure l is a side elevation of my improved motor as applied to a car, the side wall of the housing and the car-wheels being removed to give a view of the construction and arrangement of the motor and its gears. Fig. 2 is a plan view of the same with the top of the housing removed. Figs. 3 and 4 are diagrammatic side elevations of modified constructions, the side of the housing in each case being removed to show the interior arrangement of the parts.
In the drawings, 2 represents the car-body frame mounted upon the axles -l and 5, having carrying-wheels 6. Mounted upon the axle 4 is the armature S of the motor A.
Surrounding and concentric with the armature are the field-magnets 10, preferably inclosed in a case, as shown, the cone-shaped ends or yokes 12 thereof taking bearing upon the inwardly-projecting end 14: of the saddles 16, which support the frame upon the axle.
Any suitable means may be employed for connecting the line-wires properly with the motor, a convenient form being indicated in Fig. 2, in which insulated rings 18 and 20 are secured upon the yoke 12, and respectively connected with the commutator-brushes 22 and 24: and with the line-wires a and b by means of suitable contacts 26 and 2S.
WVith the construction shown in Figs. 1, 2, and 3 the armature is mounted upon the axle 4, and the field-magnets are provided with a gear-wheelSO concentric with the axle, which is connected with a similar gear-wheel 32 upon the axle 5 by means of two intermediate gears 8d and 36, all of the gears being preferably inclosed in the housing 38. It will thus be seen that with the opposite rotations of the armature and field-magnets a like rotation is produced in the two axles, one taking power from the armature and the other from the field-magnets. The advantage of this con struction is apparent in that the relative effeet or influence of the armature and fields upon each other, with both rotating oppositely at a given speed, is the same as if one were fixed and the other rotating at double the speed, and by connecting the rotating parts respectively with the car-axles the motor can actually be operated at double the speed of a motor as ordinarily constructed to run the car at the same speed, thereby promoting the efficiency of the apparatus.
In Fig. 3 is shown a diagrammatic view of a modified construction provided with a smaller gear 40 upon the rear axle, whereby the speed of the axle connected with the field-magnets is faster than that of the fields.
In Fig. i isshown a diagrammatic view of another modified construction in which the motor is mounted intermediate of the axles, the field-magnets being geared directly to a gear 42 on one axle and the armature by two intermediate gears to the other axle.
Vhile I have shown and described the field-magnets rotating about the armature, it
is obvious that their relative position may be reversed and the same practical result attained in the operation of the motor.
I claim- 1. The combination, with the armature mounted upon one of the car-axles, of the rotable field-magnets concentricwith said armature, the gears carried by said field-magnets, and gears connecting it with the other car-axle, substantially as and for the purposes set forth.
2. In an electric-railway motor, the combination of the armature connected to one axle and the concentric rotatable field-magnets connected to the other axle, whereby the opposite rotations of the armature and fieldmagnets are transmitted and applied to the HENRY M. BYLLESBY.
