JOHN C. HENRY, OF NElV YORK, N. Y.
'OVERH EAD ELECTRIC RAILWAY.
SPECIFICATION forming part of Letters Patent No. 499,112, dated June 6, 1893. Applicationfiled September 3, 1890- Serial No. 363,847- (No model.)
To all whom it may concern:
Be it known that I, JOHN C. HENRY, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Electric Railways, of which the following is a specification.
Leading features of my invention consist in, first, an arrangement in which the positive conductor is protected by the negative or return conductor arranged vertically above it; second, a feeding main for the out-going current and communicating through the supporting posts with the positive wires of the overhead conductors said main consisting preferably of a cheap material of low resistance such as described in my application for patent filed September 27, 1889, Serial No. 325,244, said main being inclosed in a connected series of iron piping through which the current from the motor is either grounded or returned to the dynamo.
Other features of my invention will be found described in the sequel.
Referring to the accompanying drawings which form a part of this specificationz-Figure 1 represents by side elevation a motor-car and a portion of an electric railway illustrating myimprovements. Fig. 2 is aperspective view showing a portion of the overhead system of conductors. Fig. 3 is a view taken at right angles to the conductors showing two sets of wires for a double track line. Fig. 4 represents my buried compound main applied to a system of overhead conductors which are supported from bracket-projections of the groundposts without the intervention of supporting cross-wires.
1 may represent the track-way of an electric railway. 2 may represent a car equipped with a suitable electric motor 3 which has separate positive and negative communication with the overhead conductors by means of traveling contacts to be presently described.
The outgoing and returning wires of my system of overhead conductors are, by means of hangers H, h, suspended from and have electrical connection with wires g, f which are stretched diagonally or in zig-zag fashion across the track-way from the tops of ground-poles or posts f of which thereis a line of post-s on each side of the track, the posts on one side being, for that purpose, placed opposite to the mid-distance between those on the other side. My preferred construction of these posts is substantially as represented in Fig. 1, that is to say, each post consists mainly of a tapering open and hollow frame composed of iron rods 4 bound at proper intervals by hoops 5 and terminating in suitable pillars 6 to which the cross-wire f for the return current is directly attached and with which it is by said attachment placed in electrical communication, and upon which the cross-wire g for the active or out-going current is supported by means of insulating brackets r. From the cross-wire g a wire e is insulated from and conducted down the interior of the post to a main b of low-resistance consisting preferably of a line of electricallyjoined discarded track-rails of which the terminal one has electrical communication with. the positive brush of the dynamo. The said main being embedded in cement (Z or other suitable insulation, is inclosed in a line of iron piping c Whichconnects with the negative brush of the dynamo.
Figs. 1, 2 and 3 represent my improvement adapted to a set of elevated conductors for a double track and with the wires-for the homegoing or spent currents suspended at a slightly higher elevation than and so as to serve as guards or protectors to the wires which convey the outgoing or working currents. In such track-arrangement, While the suspenders H, H of the active wires hang perpendicularly the suspenders h, h of the returnwires are spread obliquely so as to be out of contact with and to protect the former-see Fig. 2.
The above-described system for conveying electricity to a plurality of electrically propelled cars from a stationary source of current is thought to possessanumberof advantages over existing devices for the same purpose.
For example: As to the buried main or service-conductor of low resistance and very cheap material connected at numerous intervals with the overhead wires, it enables a current of large amprage and low voltage to be applied in multiple to all the cars on the line at the same be approached or handled with entire safety. 7
i As to the arrangement of spent or grounded current-wires above and with their suspenders straddling the line of active wires, the former operates to guard the latter against accidental contact of an arc-light or other of exposed working conductors, buried feeding conductors, and a metal ground-post which incloses and protects the insulated intermediate positive conductor and which is itself in direct electrical communication I above with the negative conductor and below with the negative main.
2o high-voltage wire.
Inthedescription and claims I have, for the sake'of clearness, referred only to the negative Wire as the grounded wire, but it is obviously unimportant and equally within my invention whether I ground the negative or positive wire or whether the negative or the positive wire is located above the other, proi viding that, as herein described, the two may beperfectly insulated from each other. 0 In an earlier application, serially numbered 325,244, filed on the 27th of September, 1889, I have shown and claimed an electric railway system comprising hollow posts staggered 011. each side of the track, diagonal guy wires 3 5 stretched continuously from post to post and a buried feeding conductor, the said guy wires forming a part of theelectric circuit andbeing connected to-the working conductors suspended therefrom. as well as to the buried feeder, the latter connection. being made by branch conductors passing through the hollow posts. The object of the present application is to cover certain improvements on that system.
Having thus described. my invention, the following iswhat I claim as new therein and desire to secure by Letters Patent:
1. In an electric railway, parallel aerial wires suspended over the roadway, said wires carrying current of different signs, one of said wires being located above and acting as a guard to protect the other.
2. In an electric railway system, the com.- bination'of a source of electricity and an elec: tric circuitconnected therewith and having /'both outgoing and return- Wires suspended over the railway, one of said wires being grounded and the other insulated from the ground and one being supported over the other, to protect it, substantially as set forth.
3. In an electric railway system, the combination of a source of electricity, an electric circuit connected therewith, and a motor or motors having means of connection. with both outgoing and return wires thereof, one of said wires being grounded and the other being insulated and the grounded wire being supported over the railway above the other, substantially as set forth.
4. In an electric railway system, the combination of a source of electricity, continuous main conductors extending along the said railway and connected to opposite poles of said source, working conductors, and metal posts arranged along the railway for supporting said working conductors and electrically connecting one of the same, with one of the main conductors, substantially as setforth.
5. In an electric railway system, in combination with an overhead working conductor,
metal posts supporting the same and electrically connecting it to ground, substantially :as set forth.
6. In an electric railway; the combination 7. In an electric railway, the combination of overhead working conductors, feeders connected thereto through ground-posts and positive supporting wires, and negative supporting wires placed above and protecting said positivesupporting wires; substantially as set forth.
8. In an electric railway, the combination of the negative cross supporting wires and the straddling suspenders therefrom which support and connect therewith the negative line-wires at two points so as to protect the positive wires without liability to short circuit therewith, substantially as set forth.
9. In an electric railway;-the combinat on with a stationary source'ofcurrent and-with collectors on the motor cars, of the compound buried main, one or more lines of ground-posts and positive and negative linewiressupported therefromand having through said posts numerous connections, the positive line-wire through insulated conductor with the supply-main and thenegativelinewire directly through said posts with the return main; substantially as set forth.
