ELECTRICAL DEVICE FOR OPERATlNG STEAI'W VVHISTLES...
SPECIFICATION forming part of Letters Patent No. 363,079, dated May 17 1887.
Application filed May 24, 1886. Serial No. 203,069. (No model.)
To all whom it may concern.-
Be it known that I, WILLIAM M. PEASE, a citizen of the United States, and a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Electrical Devices for Operating Steam-'Whistles, of which the following is a full, clear, and exact description.
In boiler-shops, iron-mills, and other manu factories where there is continual noise, it is often difficult to signal the employs for any To occupy time by sending messengers from the office to the workshop occasions delay, and is the source of considerable expense. If a bell be used, its tones are often not distinguishable above the noise of the shop.
-It is the object of this invention to provide means by which a steam-whistle can be operated from the office or any other desired part of the works, and prearranged signals be given which may beeasily distinguishable above the din and confusion of noises.
The invention consists of the hereinafterdescribed means for attaining said object.
The drawing represents a view, partly in section, of a steam-whistle and my improved device for operating same.
A represents the socket of the whistle, by means of which the latter is secured in posi tion.
Bis thesounder, and O a cylindrical cas ing carrying upon its lower extremity the defiector c.
D is a conical valve, whose stem works within the casing G, and is secured to or made integral with a soft-iron disk, (6. The disk d rests upon and the casing G is secured to a plate, 6, of brass or other substance not capable of magnetization. This plate is secured to the poles of an electro-magnet, E. Said poles are extended inwardly above the iron disk (I, for the purpose hereinafter specified.
bular casing, f, contains a loose rod, F, whose lower extremity rests upon the top of the disk d. Upon the top of said rod rests a lever, f, one of whose extremities is hinged or pivoted, and the other extremity carries a weight, f". One end of the magnet-coil is connected with a push-button and the other end with one pole of a battery. The free pole of the battery is connect-ed with the contact-point of the button.
The operation of the invent-ion is as follows: The weightf is sufficient to hold the valve D tight against its seat under normal steampressure, and the magnet E (when the circuit is completed) is of sufficient strength to lift said valve and weight when in conjunction with the pressure of steam. (lonsequentl y when the operator in the office presses upon the button, and the circuit is thereby completed, the magnet will be energized, the valve lifted from its seat, and the whistle sounded.
By the use of a preconcerted code of signals various messages, orders, and the like may be communicated through the whistle, which it would be almost impossible to effectually do in any other manner, it being easy to distinguish the call of the whistle where a bell or other alarm would be inaudible.
Having thus described my invention, what I claim is A whistle valve socket carrying a deflector, c, and a valve carrying at the upper end a softiron disk, (1, the brass plate 6, and the magnet E, supported upon said brass plate and having its poles extending above said iron disk, in combination with a lever carrying an end weight, and a rod, F, to bear on said disk, and a battery, substantially as shown and described.
