Application filed March 26, 1903, Serial No. 149,686.

To all whom it may concern:

Be it known that I, JOHN L. OREVELING, a c tizen of the United States, residin in the city, county, and State of New Yor have invented a certain newand useful Improvement in Electric Trains or Vehicles, of which the following is a s ecification, reference belng had to the rawing forming a part thereof.

I My invention ertains to that class of trains made up of detachable vehicles as of carsand adapted to run over anordinary track as used in regular railroad practice now employing the steam locomotive to draw trains made u of detachable cars and has for its particu ar object to produce means and energy derived therefrom e utilized to produce torque upon the Wheels of several of the vehicles composing the train by means distributing the energy derived 1n what might be called the locomotive to motors throughout the train tending to rotate several of the Wheels of the various vehicles upon which rest the weight of the train and therefore causing the tractive eflort to be a function of the wei ht of the entire train rather than that of the locomotive merely as in ordinary steam railroad practice.

Figure I of the drawing illustrates diagrammatically one form of train embodying my invention. Fig. II. illustrates. diagrammatically a locomotive similar to the one shown in Fig. I. in which internal combustion motors are depicted in place of the steam turbines of Fig I. 7

Like numerals in the figures are used to parts.

Referring to the-drawing, articularly Fig.

I., (1) represents the vehic e in which the energy used for pro elling the train is derive from the fue. (2) represents any suitable sort of tender for the transportation of the fuel. (3) represents a car of any suitable type such as may be used in making up the train. (4) represents the boiler, in merely indicated as of the marine type, readily permitting the use'of the corrugated suspension furnace and adapted to generate steam at the expense of fuel of.

any descri tion as coal, oil, etc., which may be carrie in the tender (2). v From the boiler (4) the pipe (5) leads to what might be termed a steam controller (6) from which is led the rod (7) to the lever (8) serving to actuate said controller. The numerals (9) lndicate prime movers adapted to produce rotary motion at the expense of the energy derived from the fuel, in this instance being indicated diagrammatically as steam turbines and readlly controllable by the engineer through the instrumentality of the lever (8) and apparatus cooperating therewith. From these motors the exhaust may be led away in any suitable or'desired manner. The numeral (11) indicates dynamos or generators direct connected with the turbines (9) and from which the leads (12') are carried to a suitable electric controller (14) provided with operating handle (15) and reversing lever (16). The field circuits of the generators may be carried as by cable (13)to controlier (14) and governed by the engineer through the instrumentality-of lever (20).

(17) re resents the cable leading from the control er (l4) and is connected from car to car as by flexible connection (18) and is connected with regard to the controller (14) and the various motors (19) in operative relation to the various Wheels of the several cars as to be capable of rotating the same, so that the said motors are under control of the controlling device designated as (14).

A practical operation of my improved system is as follows: Fuel is taken from the tender (2) and used for the production of steam in the boiler (4) which passes through pipe (5) and steam controller (6) to the'several prime movers or motors located in this car or locomotive and under control of the engineer as by lever (8). In starting the train the motors or turbines may be started and brought to the proper speed by means of lever (8) and the generators may be regulated to give their required volta e as by means oflever (20) governing the fie ds thereof. Current may be taken from the generators and fed to the various motors throughout the train as by feeders (17) and (18) and con trolled as in any of the ordinary multiple unit systems by means of controller (14) operated b the engineer by means of lever (15). In t s way the energy derived from the consumption of the fuel can be caused to rotate the Wheels throughout the train by the various motions in such manner as to greatly increase the tractive effort above that of the locomotive Whose draw-bar ull is a functionof its own weight upon t e rails. The train may be runand regulated in this llt manner as may be desired and in stopping the current may be properly regulatedby the lever (15) and the motors (9) allowed to revolve or stop as may be deemed proper according to the length of time of the said stop. It will be noticed that I have shown the enerators as mounted in pairs and it will be obvious that these may be connected in multiple or in series with each other and may be connected from the controller so as to may be run at practically their maximum speed andefiiciency and that at all times the control of all the drivin throughoutthe train be directly under the engineer having also the control of the prime motors.

It will be obvious that any kind. of fuel may be used and that an internal combustion motor, or' any other motor derivin its energy direct without the intervention 0 boilers or other such means, may be employed, also that any number of motors an generators may be employed and have their mutual relations altered inany desired manner, and

that only part of the motors may be used when drawing light trains and the whole equlpment pressed into service when drawing heavy trains, or any other such combina tions be made as desired, without departing from. the spirit of my invention.

The above description of the construction and operation of my improvement in electric trains, with reference to Fig. I. may be readily understood with res ect to Fig. 11., in that, all of the electric devices, connections, and operations are the same in the locomotives shown in Fig. I. and II. and, indicated by the corresponding numerals, and the internal combustion motors (9) perform the same functions as the steam driven motors of Fig. I., while (6) represents thethrottle of the motors (9), to which the charge may be led from any suitable source,

as indicated by the pipes (5), said throttle (6) being under control of the engineer, as by lever 8).

I do. not wish in an way to limit m self to any construction s own in the rawing which is merely a diagram illustrating one form of my invention and from which great variation may be made and still within the scdpe of said invention.
