RUDOLPH M. HUN ER, OF PHILADELPHIA, PENNSYLVANIA.
ELECTRlCALLY-PROPELLED VEHICLE.
SPECIFICATION forming part of Letters Patent No. 418,893, dated January '7', 1890.
Original application filed June 5, 1889, Serial No. 813,217. Divided and this application filed September 16, 1889. Serial No. 324,076. (No model.)
To (0 whom it may concern:
Be it known that I, RUDOLPH M. IIUNTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Electrieally-Propelled Vehicles, of which the following is a specification.
My invention has reference to electricallypropelled vehicles; and it consists of certain improvements, which are fully set forth in the following specification and shown in the accompanyingdrawings, which form a part thereof.
This application, Case 108, is a division of my application No. 313,217, filed June 5,1889, and relates, generally, to electric cars or other vehicles, and may be used in conjunction with batteries carried by the ear or vehicle or with line-conductors extending along the railway, from which the motors derive their current.
Specifically the invention relates to the means employed for connecting the motors on the axles, preferably so that each is inclependent in its motions with respect to the other. Both motors are supported by frames from both axles; but each is connected so as to rotate different axles. In detail each motor is supported by frame-work, which enables the motor to be journaled on one axle with a flexible connection with the other axle, whereby there shall be no binding, and yet the motor shall be positively coupled with the axle which it drives.
In the drawings, Figure l is a sectional elevation on line 00 00 of Fig. 2, showing my improved manner of supporting the motors on the axles. Fig. 2 is a plan view of same. Fig. 3 is a sectional elevation of a modification of same, taken on line y y of Fig. 4; and Fig. at is a plan view of the devices shown in Fig. 3, with the wheels and parts of the axles cut away.
A are the axles. I3 are the wheels thereof.
0 are the worm-wheels, secured to the axles by keys, so as to rotate the axles with them.
D is a dust-box inelosing the worm and worm-wheel, and is journaled on the hub of the worm-wheel or the axle.
E is the worm, which meshes with the worm-wheel,and is journaled in the frame or box I).
F are frames which are secured atone end to the boxes D, and thereby journaled to the axles at (Z, and have their other ends provided with pins which extend throughlinks lr, supported upon the axles, with provision for lateral movement. In practice there may be one or two of these frames and motors. I have shown two, and they are journaled and hung from opposite axles. It will thus be seen that each motor II, secured upon the frames F, is in effect journaled to the axles which it rotates, and is pivoted by a flexible or universal joint on the other axle and with provision to allow the axles to have any rela-' tive movement desired, as in jumping switches, frogs, cross tracks, &c., without binding on the journals or displacing the mo tor-connection with the axle.
I is the motor-shaft, and may be connected directly with the worm E or through a flexible coupling 2', which permits of a limited amount of spring to the parts without binding. I prefer to hang the pivoted end f of the frame F to the link below the axle. These two motors are thus free to have all kinds of relative movements, and are carried by the axles independent of the carbody, which is supported on springs in the usual way.
L is the regulator, and may be carried on the car-body, if desired, and is connected by flexible conductors M with the motors II II, the flexibility thereof permitting the free independent movements of the motors without rupture of the conductors.
N is a source of electric supply, and P is a circuit for supplying current from N to the regulator L, and thence by conductors M to the motors. This source of power N may be batteries carried by the car, or current may be supplied by the usual line-conductors extending along the railway, and current-collectors carried by the car-as, for instance, is set out in Letters Patent No. -.i=0O,9I6, April 9, 188.), or No. 403,192, May 15, 1889, granted to me.
It is not essential that worm and wormwheel gearing shall be used between the y Having now described my inventiomwhat I axles and motor shaft, nor that the motor claim as new, and desire to secure by Letters shall be supported without elasticity. In Figs. 3 and 4 I have the motor ll, journaled to one axle A by journals (1 and frame I), and connected at the other or free end to springs K, which terminate in a pin f, journaled in a link or frame G, loosely journaled on the other axle A. This frame or link G in this case may be double and have extensions 9 loosely supported on the other axle, forming a light frame. As shown, the motor-shaft I is geared to the axle A by gears E O, and the gearing and motor are free to move about the axle, since the spring K and link G permit such movement. It is also evident that the axles may move independently and relatively to each other without binding of the motor on the axle.
It is apparent that the frame D, the motorframe, and springs K of Figs' 3 and 4 correspond to the frame D F and motor of Figs. 1 and 2, and hence, broadly considered, the construction shown in the various figures are equivalents. In Figs. 3 and 4: I have only shown one motor connected to drive one axle; but it is evident that the apparatus may be duplicated, as in Fig. 2, to drive both axles from separate motors.
I do not limit myself to any special form ofgearing, nor to the minor details of construct-ion, as they may be modified in various ways without departing from the spirit of my invention.
Matters shown and not claimed herein form subject-matter of other applications; hence such matters are not dedicated to the public, but. form subject-matter of my application of which this is a division, and my applications Serial No. 215,199, of September 23, 1886; Serial No. 217,3i6, of October 27, 1886; Serial No. 224,150, of January 12,1887; Serial No. 264%56, of February 18, 1888; Serial No. 268,360, of March 24, 1888, and Serial No. 271,1at1, of April 19, l888that is to say, I do not claim, broadly, a motor journa-led upon the axle and supported elastically at the other end either through the axles directly or by a frame supported by said axles; nor a construction in which a frame is journaled to one axle and flexibly supported above the other axle, and having a motor supported by the frame and gearing with the axle to which the frame is journaled; nor two frames sup ported by the axles, combined with a motor for each frame, and connecting-gearing between the motors and axles whereby each motor drives different axles with or without flexible electrical connections between them; nor two electric motors supported partly by each axle and respectively connected by power-transmitting connections with different axles and with or without connecting flexible electrical connections, as said features are set out and claimed in my applica tions above referred to.
