SYSTEM OF ELECTRIC LlGHTlNG.
SPECIFICATION forming part of Letters Patent No. 335,060, dated January 26, 1886.
Application filed June 26, 1885. Serial No, 169,825. (No model.)
To all whom it may concern;
Be it known that I, HARRY M. DoUnLEDi-ir, of New York city, in the county and State of New York, have invented a certain new and useful Improvement in Systems of Electric Lighting, of which the following is a specification.
My invention relates to systems of lighting by electrical incandescence, and more particro ularly to the supplying of street-lamps from such a system.
The object I have in view is to provide in a simple and efficient manner a separate control of the street-lamps from the central station, so
that such street-lamps can be turned off and on from the station, the streetlamps being supplied with current from the same source that, supplies the domestic lamps, and the conductors for the domestic lamps being 2o utilized in conveying currentfor the streetlamps.
rllhe invention consists in the means employed for accomplishing these general objects, and also in details used in the carrying 2 5 yout of these objects practically in connection with a domestic system of electric lighting, to provide for safety for the regulation of the street -lamps independent of the domestic lamps, and for permitting the turning on and 5o off of the street-lamps without noticeably affecting the domestic lamps.
The invention is especially applicable to the Edison three-wire or compensating system, al-
though also applicable to a simple two-wirev system, as will be hereinafter pointed out.
In the accompanying` drawings, forming a part hereof, Figure 1 is a diagram of parts of an electric-lighting system illustrating my invention. Figs. 2 and 3 are modiflcations thereof, and Fig. 4 is a further modification.
lVith reference more particularly to Fig. 1, A represents a central station for a threewire or compensating system provided with dynamos (not shown) for generating the current connected with the omnibus conductors 1 2 3 in the station. From these omnibus conductors extend,as usual,feeders B B,each composed of three conductors, 4 5 6, to sections G G/ of the system. These sections are portions of the domestic mains, each composed of three 5o conductors, 7 8 9, such domestic mains being connected together by intervening domestic mains, as shown by the crossing lines D at the right of Fig. 1, the whole forming a connected system of positive, negative, and neutral or compensating conductors supplied by feeders from the central station. From these domestic mains house-circuits extend, and in these are located domestic incandescing electric lamps a. The domestic system is provided with all 6o the usual appliances for regulation, control, and safety, which it is not thought necessary to describe herein. y
For the street-lamps I provide separate and independent single part mains 10 11,connected 65 with the station by single part feeders 12 13. The feeder 12 is connected at station with the positive omnibus conductor 1,while 13 is connected with the negative omnibus wire 8. Street -lamps b are connected between the 7o mains 10 11 and the neutral or compensating conductor 8 of the domestic mains.
Throughout the domestic system, wherever it is desired to place street-lamps, the streetlamp mains will extend. These will be divided into a suitable number of scparateindependent sections, and as many of the single part feeders 12 13 will be used as there are separate divisions to the street-lamp mains, such feeders being preferably divided between So the two sides of the circuit, half of these being connected with the positive omnibus couductor and half with the negative omnibus conductor.
At the central station each street-lamp feed- 8 5 er is provided with a switch, o, for making and breaking the circuit of the street-lampsA connected with the particular division of the street-lamp mains supplied by the feeder, and each of such feeders also has an adjustable re- 9o sistance, E, which may be a wire or lamp resistance located in the station. This resistance is employed for regulating the streetlamps in candle-power; but its principal use is to permit the street-lamps to be thrown into and out of cireuitgradually, the resistance being first gradually introduced into the feeder before the switch is opened, and being gradually cut out of the feeder after the switch is closed. The street-lamps being thrown on and off one division at al time, and by the gradual cutting out and in of the resistances, the effect upon the domestic lamps will not be noticeable. Each street-lamp feeder also has a fusible safety-catch, d, proportioned to carry the maximum normal load of the feeder.
Where it is desired to operate street-lamps beyond the limits of the domestic mains,which is often the case,I extend the neutral conductor 8 of the domestic mains by lines 14 15, connected together at their outer ends. Streetlamp mains 16 17 are run parallel to suchneutrai lilies 14 15, and are connected by positive and negative feeders 18 19 with the station, the effect of the full electro-motive force being obtained by this arrangement.
As a modification of the system it is evident that some or all of the street-lamp mains may be connected directly with the station, as shown in Fig. 2. This would be done with mains close to the station and not themselves of great length.
In applying the invention to a simple twowire domestic system, Fig. 3, the street-lamps will be located between positive and negativev street-lamp mains and domestic mains of opposite polarity.
A number of street-lamp mains would preferabl y be used divided between the two sides of the system, as before explained with reference to the three-wirc system.
All ofthe street-lamp feeders from the station, whether to mains within the limits of the domestic system or beyond, as well as all direct connections of street-lamp mains to stations, will be provided with switches, adjustable resistances, and safety catches, as before eX- plained.
I prefer in some cases to dispense with the feeders to the street-lamp mains within the limits of the domestic system, and to supply such street-lamp mains from the street-lamp mains outside the limits of the domestic system, the two sets of mains being connected together and the feeders running to the outlying mains only. This arrangement, which is shown in Fig. 4, is desirable, in order to sccure the best distribution of the current.
Vhat I claim is- 1. The combination, with a domestic system of lighting by electrical incandescence, of an additional conductor connected independent of the domestic system with one pole of the source of electrical supply at the station, and lamps connected between such additional conductor and a conductor of the domestic system, substantially as set forth.
