WALTER H. KNIGHT, OF NEW YORK, N. Y.
ELECTRIC LOCOMOTIVE.
SPECIFICATION forming part of Letters Patent No. 548,371, dated October 22, 1 895.
Application filed June 15,1888. Serial No. 277,202. (No model.) 7
To aZZ whom it; may concern:
Be it known that I, WALTER H. KNIGHT, a citizen of the United States, residing at New York, in the county of New York, State of 5 New York, have invented certain new and useful Improvements in Electric Locomotives, of which the following is a specification.
My invention relates to an electrically-propelled vehicle; and it consists in a certain arrangement of the propelling motor relative to the vehicle.
The invention has reference to that class of electric locomotives in which the motor is centered about a driven axle, whereby any slight rotating movement which it may have upon its bearings, does not affect the proper working of the power-transmitting connections, whatever these latter may be.
My invention applies equally well to all locomotives of this class; but I preferably support the motor inside the axle,journaling one end upon the axle and upholding its free end by a connection to the framing, which is supported on the axle independently of the springs carrying the car-body whereby the strain necessary to hold the motor in place comes not upon the car-body, but upon the axles themselves. This connection may be made through a spring, when necessary, in order to give the armature end of the motor ayielding suspension, allowing a slight rotating movement.
My invention is illustrated in the accompanying drawings, in which- Figure 1 is a plan, Fig. 2 a transverse section, and Fig. 3 is a side view, of my device.
In the figures, A is an electric motor centered about an axle G, and in the specific case shown its free end extends inward between the axles and is upheld by downward pressure upon the framing, though I do not limit myself to this specific manner of upholding its free end. I journal the motor to the axle through an extension piece projecting directly from the yoke end of the motor. In this way the heaviest part of the motor is supported directly upon the axle and the armature end is removed, leaving room between it and the axle for an intermediate speed -reducing counter-shaft. Both the armatureshaft D and the counter-shaft have their hearings in two arms F F extendingforward from yoke B upon opposite sides of the motor. This arrangement constitutes an independent framing movable as a whole relatively to the truck-framinghereinafter described.
H H are side bars which join the axles and are mounted thereon by means of suitable boxes R R outside the wheels, preferably without any intervening springs.
G is a crossbar joining the side bars H H. The car-body is supported in a well-known manner from the boxes RR on the ends of the axle with intermediate springs K. The free end of the motor has a connection to transverse bar G, which may be through a spring, if desired, thereby spring-centering the motor as a whole about axle C. It will thus be seen that I have a truck-framing composed of side bars H II and transverse bars G, which upholds the free end of the motor, and which, being supported independently of the car-springs, takes the strain of the motor entirely away from the car-body and puts it directly upon the axles. Hence the motor when in operation does not tend to jerk the car-body up or down, and, in fact, the movements of the car-body and the motor have no effect upon each other.
It is evident that the utility of the combination between the independent'framing and the motor is unaffected by the particular disposition made of the motor or by the particular kind of connection for upholding its free end, while, on the other hand, the journaling of the yoke end of the motor on the axle is in itself advantageous by whatever means its free end is held in place.
I claim as my invention-- 1. The combination with the oppositeailes of a vehicle, of an intermediate electric motor spring centered about one axle, at its yoke end a frame joining the axles from which the free end of the motor is suspended, and a carbody having a springsupport on the axlesindependently of said frame.
2. The combination with the two axles of a vehicle and a truck-framing joining the same of an intermediate motor having its yokejournaled on one axle, a frame extending from said yoke carrying the countershaft, and a spring support upholding the free end of the motor.
3. The combination of the axles of a railway truck and a framing mounted thereon,
ICC
with an electric motor having at its yoke end a bearing upon the axle independent of the framing, aconnection between the motor and framing, whereby the free end of the motor is upheld, and a car-body having a spring support independent of said frame.
4. The combination of a framing joining the axles of a railway truck, with an electric motor centered at its yoke end about one of the axles, and having both armature and field magnets free to rotate about the motor bearings, a mechanical connection between the framing and motor, whereby the latter is preserved against excessive displacement, and a car body having a spring support independent of said frame.
5. The combination of frame bars bearing directly upon the axles of a truck, and an electric motor having at its yoke end a bearing upon one axle at a point between the frame bars, with a mechanical connection between the motor and frame bars upholding the free end of the motor and a car-body having a spring support independent of the said frame.
6. The combination of the frame bars hearing directly upon the truck axles and outside the wheel, and a transverse bar between the same, with an electric motor havinga bearing at its yoke end upon the axle between the wheels and a connection to the transverse bar upholding the free end of the motor.
7. The combination of the truck frame joining the axles, with an electric motor havinga bearing at its yoke end upon the axle, and a connection to the frame, at a point intermediate between the axles upholding the free end of the motor and a car-body having a spring support, independent of said frame.
8. The combination of the axles of a railway truck and a frame joining the same, with a propelling electric motor having the axis of its field magnets at right angles to the axle, the yoke end being journaled on the axle and the armature end having a yielding suspension from the said truck frame.
9. The combination in an electrically propelled vehicle, of side bars joining the journal boxes outside the wheels and holding them in position, a motor centered on an axle of the vehicle and provided with a framing independent of the side bars holding the armature and counter-shaft, with a connection between said framing and the sidebars upholding the free end of the motor.
10. The combination in an electrically propelled vehicle of a motor centered on an axle thereof, a framing consisting of the motor yoke, and side arms having a bearing on the axle between the wheels, and carrying the armature and countershaft with a connection from the free end of the motor to outside journal boxes, by which the said free end is upheld independently of the car-body.
11. The combination in an electrically propelled vehicle, of a motor centered on an axle thereof, a journal box between the wheels supporting one end of the motor, a framing attached to boxes outside the wheels, a vehicle body spring-supported on the said boxes, and a connection between the framing and the free end of the motor, by which the latter is supported.
12. The combination with a driven axle of a railway truck, of an electric motor having its yoke end journaled directly upon one axle independently of the truck frame, a yielding suspension upholding the armature end and power-transmitting connections between the armature and axle.
13. The combination of the electric motor havingabearing at its yoke end upon one axle of the truck, with a truck frame having a transverse bar as G, a motor frame supporting the armature and countershaft, and a connection to the transverse bar, upholding the free end of the motor.
let. The combination of an electric motor having a hearing at its yoke end upon an axle of a railway truck, and a yielding suspension upholding the armature end at a point between the car axles, and power transmitting gearing between the armature and axle, substantially as set forth.
15. The combination of a driven axle of a vehicle and a propelling electric motor having its yoke end bearing upon the axle, and a connection between the motor and vehicle at an intermediate point between the axles upholding the free end of the motor.
16. The combination of a railway truck and an electric motor having its yoke end journaled upon an axle of the truck, of a gear wheel on the said axle outside the motor bearing, and power transmitting connections between the armature and gear wheel.
17. The combination of a frame joining the axles of a motor truck with an electric motor having its yoke end journaled upon one axle independent of the frame, and a mechanical connection between the motor and the frame, upholding the free end of the motor.
18. The combination of a driven axle of a vehicle with a propelling electric motor having an extension from its yoke end, forming a bearing upon the axle, a yielding suspension for the free end of the motor and power transmitting connections, substantially as described.
19. The combination with a driven axle of an electrically propelled vehicle, of a motor having its yoke end journaled on said axle, arms extending horizontally from said yoke parallel to the field magnets, and an armature and countershaft jourualed in said arms, the arms and yoke forming a rigid framing holding the armature and countershaft in alignment with the axle and each other, and supported as a whole by a connection to an independent framing, bearing on the axles of the vehicle.
