IMPROVEMENT IN STEAl-ENGINE GOVERNORS.
The Schedule referred to in theseLettera Patent and making part of the same.
To all whomz't may concern: p
Be it known thatl, J EREMIAH A. MARDEN, of Boston, .in the county oSgffolk, and State of Massachusetts, have invented c ertain Improvements in the Stop- Motion of Steam-Engines, of which-the following is a full, clear, and exact description, reference being had to the -accompanying drawings, making part of this specification, in which-- Figure 1" is anelevatiou representing the position of my improvements when the valve is open and the engine running.
Figure 2 is an elevation showing my improvements in the position they occupy'when the valve is closed to stop the engine. p
Figures 3 and 4, details to be referred to.
In the event of an accident occurring in a building where a steam-engine is employed, it is frequently of great importance to stop the machinery with as little delay as possible. This maybe done by the engineer in the engine-room as soon as knowledge of the accident is communicated to him. Where, however, the accident occurs at a point remote from the engineroom, considerable delay is incurred in thus'communicating with him.
Ihe object of my invention is 'to provide a ready means for instantly closing the valve from any remote point in the building; and
My invention consists in so constructing the series of levers which connect the governor with the valve, that one of the levers may be raised by a wire or cord leading from a point 4outside of the engine-room, so as to release and allow one of the levers, which is connected with the valve, to drop, and instantly close it, as required.
And my invention also consists in a device for automatically releasing the levers so as to close the valve 1ng support-s the'reccptacle B for containing oil-v or other duid, and any suitable devices''or regulatingthe speed of the engine, whicb,as they form no part of' my present invention, are not here represented.
C is the weighted scale, or graduated lever, secured tothe rocker-shaft D connected with the devices for governing the speed within the receptacle B.
To the outer end of this rocker-shaft is secured the upper end of a lever, E, to the lower end of which is pivoted the inner end aof a lever, F, the outer end of this lever F being provided with a hook, b, which tits over-a short stud or pin, G, projecting from the side of the outer and upper 4end of a lever, H, which is iirmly secured at c to the end of the valve-stem. Upon the outer end of the stud G is pivoted an arm, to which is connected a weight, I.
Projecting in front of the lever F is a pin, d, upon which rests the weight I, when the levers aremoved back and forth while performing .their ordinary oice of controlling the valve to govern the rate of speed.
To the outer end (near the hook b) of the lever E is connected a series of cords or wires, c e e, which lead upward into the various apartments of the building containing the machinery driven by the steamengine. When the engine is running at a uniform rate of speed, the levers for governing the valve are about in the position shown in iig. 1, the weight I resting on the pin d.
Should any accident occur within any apartment outside the engine-room, the wire leading to this apartment, on being pulled, will raise the hook b ofthe lever F out of contact with the stud G, causing the weight I to fall from the pin d, and the lever H to drop into the position seen in tig. 2, thus closing the valve, thelever H being retained in this'position by an arm, f, provided with a curved slot, r/into which works a pin, h, projecting from the inside of the lever F. A When it is again desired to start the engine,the parts are returned into the position seen in fig. 1.
In the event ofthe breakage of the belt which drives the devices for governing the speed within the receptacle B, their mot-ion will be arrested, allowing the weighted lever C to drop, and deflect the lever E, so that the pin d', on the inner side of the lever F, is caused to ride up on the inclined end t of the slotted arm f suiiiciently to raise the lever F, and disengage the hook b from the stud G when the weight I falls off of the pin (l, and the lever drops, as above described, into the position seen in ig. 2, thus automatically closing the valve.
Claims.
What I claim as my invention, and desire to secure by Letters Patent, is-
The device for closing a valve by means of' cords or wires, substantially on the principle and-in the manner herein set forth. y
Also, the arrangementwith the above, of the pin d and arm j, with its inclined end i, for automatically closing the valve on the breakage of the governor-belt, substantially as described.
