ELECTRIC TFIANSPORTATION SYSTEM.

To all It'll/.0712 it vim, concern: Beitknown that 1, WILLIAM C. MoMUR- RAY, a clt'lzen of the U Inted States of America,

" residing at""Wellsville, in the county of O- lumbiana and State of Ohio, have invented certain new and useful- Improvements in I Electric Transportation Systems; and I hereby declare the following to be a full,

. clear, and exact description of the invention,

such as will enable others skilled in the art to which it pertains to make and. use the same. i

This invention relates to improvements in electric transportation systems in Which'the cars are supported by the wires which carry the current for the motors which propel the cars.

The object of this invention is to provide I a system of this character especially adapted system embodying my invention.

for transporting general, merchandise, and

market produce.

A further object of this invention is to simplify the construction of systems of this character and to provide means for securing economy in the. use of the electric current.

My invention also consists in the features of construction and'combination of parts as described in the specification, pointed out in the-claims, and illustrated in the accon1 panying-drawings.

In the accompanying drawings, Figure 1 shows-a portion of an electric transportation Fig. 2 is an enlarged view in elevation of one of the motor-cars, showing the method of suspending the car from the wires. Fig. 3 is an end elevation of the same. Fig. 41s a diagrammatic view showing the arrangement of wires on a downgrade; Fig. 5 is a diagrammatic view showing the arrangement. of wires at a station. Fig. 6 is a view showing same in side elevation.

Again referring to the drawings, 1 represents the supporting-posts for the wires 1 extending arms 4. 5 0.

Specification of Letters Patent Application file}. November 20, 1965. Serial No. 288,219.

The wires on one side of the posts are for the cars traveling in the opposite direction. Each pair of wires is suitably connected with anelectric generator. (Not shown;)

The motor car or driver com rises a frame or body portion 15, at each si e of which is mounted a standard 16, and the standardat one end of the frame is formed Ion er than the standard at 'the opposite en frame, thedifference between the lengths of the standards depending on thedistance between the wires on which the cartravels. A cross-bar 17 is 'p-ivotally secured at its center to the top of each standard 16, and. at each end of each cross-bar. 17 is journaled a shaft 18. On one end of each of the shafts 18 is rigilrllly secured a grooved wheel 19,,and on eac sprocket-wheel 20. The wheels 19 on the standard atone endof the frame 15 are arranged to travel on the up er Wir,. and the wheels 19cm the standard on the opposite of the rammed April 16,1907.

opposite end thereof is secured aend 'ofthe frame 15v are arranged to travel on the wheels arenot so liable to run Off of the wires as they would be if the whole car were hung from the same wire. Near each end of the standards 16 is arranged an electric m0- tor 23, of any suitable construction. On the driving-shaft 24 of each motor is secured a gear-wheel 25. the base of each standard 16, and thereon is mounted a gear-wheel 27, which is arranged A shaft 26 is mounted n'ear to mesh with the gear-wheel 25. To'the' 'gear-wheel 27 is secured asprockrt-wheel 28. A sprocket-chain 29 operatively connects the sprocket-wheel. 28 with they sprocket- Wheel. 20. One terminal of one motor is elec-' trically connected with one terminal of the other motor by a suitable conductor 30, and one terminal of each motor is electrically connected with'the grooved wheels 19 on the adjacent standard -16,by the driving mechan ism. The electric current will therefore flow from one wire through the wheels thereon, then through the'rnotors and to the other Wire through the wheels thereon.

In Fig. 1. is shown. a trailer coupled. to the motorwhich comprises a car-body 40, which is provided with supports 4 1at eachenchand. on the ends of the supports are mounted said frame, wheels arranged on said supports In Fig. 4 is shown a method. of dispensing with the use of the current when the motor is traveling down 21, grade. This is accomplished by insulating a section of one of the wires on. the downgrade, as at a, and then shui'iting the current around the insulated section by means of n wire a. v The car will go down the grade by force of gravity and its momentum and no current Will he used in propelling it.

In Fig. 5 shown a method of constrricting it station. Where a station. is to he 10-- cnted the going and return wires srecurved away from each other, leaving a spece for the stations in between. Each station comprnv and it straight portion 36, which: maybe of wire the same as the mainline. Switchrails 37 and 38 are provided which normally form a. part of the main circuit, but which may be thrown so as to connect with the station-rails, as shown in dotted iines.

What I claim is 1 in a system of the character indicated, the combi nation oi a series of osts, outgoing and return circuits supporteti on said posts, each of snid circuits comprising two wires, one of which is arranged above the other, a centralize, a support mounted at each end of and adapted to rest on said Wires so that the frontstnd back-of the car wili be supported from different wires, a motor mounted on the said frame, and means for electrically and I a curved portion 35, preferably formed of cast-iron or a steel rm]. bent into a curve mechanically Connecting said motor and said wheels.

2. In a system of the character indicated each support, wheels mounted on said cross-- heads, the Wheels on one cross'head being arranged to rest on the upper wire and the Wheels on the other crossehead being arranged to rest on the lower wire, a motor mounted on seirLear-framc and means for electrically and mechanically connecting said motor and said wheels' In it system of the character ind'fchted the combination of a series of posts ,io utgoing and return circuits supported on"opposite sides of said posts, each of said circuits comprising two Wires oneof which is arranged above the other and means for forming a station and for transferring cars from one cir cuit to the other comprising curved tracks 'srrengedbetween theoutgoing and the return circuit v find switches connecting said curved tracl s with both of said circuits.

I In testimony whereof I'sign the foregoing specification in the presence of two witnesses.
