CHARLES E. ONGLEY, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO THOMAS IV. ROBERTSON, OF SAME PLACE,
SAFETY DEVICE FOR DYNAMO STATIONS.
SPECIFICATION forming part of Letters Patent No. 443,727, dated December 30, 1890,
Application filed June 30, 1890; Serial No. 357,228. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES E. ONGLEY, a citizen of the United States, residing .at New York city, in the county and State of New York, have invented a certain new and useful Improvement in Safety Devices for Dynamo Stations, of which the following isa specification.
It frequently happens that the fusible cut outs or other safety devices in a dynamo-circuit burn out or are operated and an arc is formed, in which case there is immediate danger of igniting the switch-board or other support of the cut-out, thus setting fire to the building inwhich the dynamos arelocated. Even if the attendant is aware of said are it -is often difficult and dangerous for him to handle the conductors, owing to the fact that the dynamo is still connected thereto and is revolving at a high speed, generating a powerful current.
The present invention is designed to overcome the above and certain other objections; and the invention consists in the general system and in certain special apparatus hereinafter described and specifically claimed.
, In the accompanying drawing, which illustrates the invention, the figure is a diagrammatic view of a system embodying the invention.
1 is a steam-engine or other motor, which is supposed to drive the three dynamos 2, 2, and 2", although, of course, any desired number of dynamos may be driven in the same manner. It is deemed unnecessary to illustrate in detail the belt or other driving-connection between the engine and said dynamos.
3 is a steam, hydraulic, or other device for stopping or controlling the engine.
4 is a valve mechanism for controlling said device, and 5 is a magnet for controlling the valve..
The parts 3 i 5 are of well-known construction and are not illustrated in detail in this case. The magnet 5 isin a circuit 6, containing a battery and several thermostatic circuit-controllers 7. The circuit is normally open and is closed by the operation of any other device for stopping the dynamo.
one of the thermostats, as indicated at the first thermostat at the left. This circuit preferably, though not necessarily, extends along the ceiling of the room in which the dynamos are situated. From each dynamo branches 8 extend to the main circuit 9. In the branches are located fusible or other cut-outs 10. I preferably place two of said cut-outs in each branch. This is to guard against accidental breakage or imperfection in any single fuse. Adjacent to these cut-outs are placed other fusible wires or strips or similar circuit-com trollers 10 in alocal circuit or branch including a magnet which controls a device for stopping the flow of current to anyparticular cut-out when said cut-out is burned or otherwise operated. Three different means are shown for accomplishing this result. At dynamo 2 the local circuit includes a magnet 11, which normally holds its armature attracted, thus preventing weight 12 from turning the disk to which it is connected. A cord or other connection extends from the disk to an extension of a commutator-brush, substantially as indicated in the drawing. In the same local circuit is a magnet 13, which normally holds the circuit 14: open. This circuit includes a controlling-magnet 15 for the valve mechanism 16 in the water-pipe 17. At
At station 2 the local circuit consists of a multiple-arc branch from the branches 8. In this case the magnet 11 controls the weight 12, which when released retracts the switch 19, thus entirely breaking one of said branches 8 between the commutator-brush and the fusible cut-out. It is evident that this switch might be arranged to break both branches, if desired.
20 is an alarm-circuit containing thermostatic circuit-cont-rollers 21, placed adjacent to the cut-outs 1O 10. This circuit includes an alarm or signal apparatus, which in this case is shown as an annuneiator 22, which is supposed to close the local circuit 2-3, ringing a gong.
The operation of the system above explained is as follows: Presuming that the engine or motor is in operation and the several dynamos being driven thereby, suppose that from any cause the cut-outin a branch 8say the first branch at the left-is burned out or operated and that an arc is formed at that cut-out. It is desirable that the are should be immediately extinguished and the circuit again put in operative condition; but, owing to the fact that a condition of high potential exists in the circuit, it is dangerous for an attendant to handle the wire. By my arrangement, however, the heat of the are immediately operates the circuit-controller 10 in the local circuit. This results in de-energizing magnet 11, thereby allowing weight 12 to descend and raising the commutator-brush e11- tirely oil? from the commutator-cylinder and absolutely stopping all flow of current to the cut-out and to the line. It is evident that by a very simple change of apparatus both commutator-brushes could be raised from the cylinder instead of one, as shown. At the same time magnet 13 is de-energized its armature falls back, closing the circuit 1-1:, when magnet 15 attracts its armature and the valve in pipe 17 is opened, admitting water to the sprinkler, which immediately extinguishes any small flame which may have been kindled by the are. The valve will then be closed by an attendant, and the wires can be handled with perfect safety to restore the circuit to operative condition. The thermostat 21 will close the circuit 20, giving an alarm practically at the same timethat the cut-outs operate.
It will be seen that by the system which has been described all dynamos except the one connected to the cut-out which is burned out will continue to deliver current to the main circuit, while said last-mentioned dynamo is put in such condition that it cannot deliver current either to the cut-out or to the line.
The operation at dynamo 2 is the same as that previously described for dynamo 2, ex cept that when the magnet 11 is (lo-energized the weight 12 shifts the belt from a fast to a loosepulley and the dynamo is at once stopped. At dynamo 2 when the cutout 10 is operated the current in the local circuitthat is, the multiple are branch including magnet 11is so much reduced that the said magnet releases its armature and allows the weight 12 to descend, opening the circuit at switch 19.
Should the sprinkler in branch 17 fail in any instance to extinguish the fire caused by the burning out of the fuse and a general fire resuit, the thermostats 7 will close the circuit (5 and stop the engine 1, thereby of course stopping all the dynamos and putting all the circuit-wires connected thereto in such condition that they will not be dangerous to firemen and other persons.
The several features of this system may be modified to a considerable extent without departing from my invention, the essential features of which are that an individual dynamo shall be rendered inoperative when a cut-out in its circuit is operated, and that all the d ynamos shall be stopped on the occurrence of a general fire.
Having thus described my invention, what I claim is 1. The combination, with an engine or motor, a dynamo driven thereby, and a eutout directly in the dynamo-circuit, of a local circuit, a device for stopping the flow of current from the dynamo to the cut-out and line, and a magnet in said local circuit controlling said device, substantially as described.
2. The combination,with an engine or motor, a dynamo driven thereby, and a fusible cut-out in the dynamo-circuit, of a local circuit, adevice for stopping the flow of current from the dynamo to the cut-out and line, a magnet in the local circuit controlling said device and normally maintaining the same inactive, and a fire-extinguisher adjacent to the cut-out, also made to work by operation of the cut-out, substantially as described.
The combination, with an engine or metor, several dynamos driven thereby, and a cut-out in each dynamo-circuit, of a local circuit at or adjacent to each dynamo, a magnet in said circuit made operative by operation of the cut-out, and a device controlled by the magnet for stopping the flow of current to a particular cut-out which has been operated, substantially as described.
a. The combination, with an engine or motor, several dynamos driven thereby, and a cut-out in each dynamo-circuit, of a local circuit at or adjacent to each dynamo, a magnet in said circuit made operative by the operation of the cut-out, a device controlled by the magnet for stopping the flow of current to a particular cut-out which is operated, and means for extinguishing fire at that cut-outsubstantially as described.
5. The combinatiomwith an engine or n1otor, a dynamo driven thereby, and a cut-out in the dynamo-circuit, of a magnet in a local circuit made operative by operation of the cut-out, a device controlled by the magnet to stop the flow of current to the cut-out and line, an electrical stopping device for the engine, and thermostatic circuit-controllers in circuit with the controllingmagnet thereof, whereby the engine may be stopped on occurrence of a dangerous fire, substantially as decribed.
6. The combination, with a dynamo, a circuit leading therefrom, and a fusible cut-out in said circuit, of a local circuit, acircuit-controller in the local circuit made operative by operation of said fusible cut-out, and means local circuit to controlled by a magnet in the to line, an alarm and circuit therefor, and thermostatic circuit-controllers in said circuit adjacent to the cutout, substantially as described.
