Description
A. BROWN. STEAM ENGINE GOVERNOR.
Patented Nov. 7
MW/ J a m STATES- ATENr Q IEQE.
AUGUSTUS BROWN, or new YORK, N. Y.
Specification forming part of Letters Patent No. 50,793, dated November 7, 1865.
To all whom it may concern:
Be it'known that I, AUGUSTUS BROWN, of the city, county, and State of New York, have invented a new and useful Improvement in Steam-Engine Governors; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 represents a sectional side elevation of this invention. Fig. 2 is a horizontal section of the same, taken in the plane indicated by the line a: m, Fig. 1. Fig. 3 is a similar section of the same, the plane of section being indicated by the line 3 3 Fig. 1.
Similar letters of reference indicate like parts.
The object of this invention is to combine with the governors of a steam-engine a'stopmotion which is so arranged that when the belt of the governor breaks or parts from some cause the throttle-valve will be closed and the engine is prevented from running away and doing some 'injury. This object is effected by using, in combination with the governor, a valve which has a rotary and'also a rising-and-falling motion, and which is so arranged that it closes by either of these 1notions. The governor-balls impart to the valve the rising-and-falling motion, and if the balls fly out the valve is closed, and it they sink down the valve is-opened. The revolving. motion is imparted to the valve by the action of a spring actingjon an arm which is secured to the stemflof the valve, and which forms the bearing for the-shaft on which the pulley is mounted, by which the governor receives its motion. By the belt passing over the pulley the spring is strained and the valve is kept open; but as soon as the belt breaks the spring causes the valve to revolve, thereby closing the same and preventing the engine from running away.
A represents a ball-governor, which is constructed in any suitable manner, and which is connected to the valve B in such a manner that when the balls fly out the valve is closed and when the balls sink down the valve is shell. If these holes register, the steam passes freely to the cylinder; but if by raising or turning the valve the hole a is brought in such a position that it is partially or wholly covered by the solid part ot the shell, the supply of steam to the cylinder is diminished or entirely cut off. v
From the center of the valve B rises a stem,
7 c, which connects with the governor, so that by the action of the same-the valve is raised or lowered, as above stated. Said stem forms the bearings for a swivel arm or frame, 0, which embraces the stem at two points, and which'is provided with a long box or bearin g for the driving-shaft d or" the governor. On this shaft 'is mounted a cone-pulley, e, and a bevel-wheel, f, which latter gears into a bevelwheel, g, on the spindle of the governor, and a belt passing over the pulley c imparts to the shaft the desired rotary motion.
From the swivel-arm G rises a forked stand}? ard, h, which straddles a lever, 1;, extending from the valve-stem 0, so that if the swivelarm is turned in either direction, the valvestem and the valveare compelled to turn with it. By the actionof the. belt, which imparts motion to the shaft d, "theswivel-arm O is drawn up against'astop, jyas shown insFig. 2 of the drawings, and in this position the holes a bin the-valve, and its shell register, (provided the valve is not raised,) and the supply of steam to the cylinder is regulated by the-action of the governor in the usual manner. A spring,'k, acting on the armC','h as a tendency toturn the samewith the valve in the direction of the arrow marked near it in Fig. 2. As long as the belt draws said arm upagainst the stop the spring remains inactive; but if the belt breaks the spring causes the arm to turn, and the valve is closed.
It is obvious that the swivel-arm and the spring acting on it might be-arranged in various different ways. I do not wish to confine The swivel-arm C and spring k, in combinamyself to the' precise arrangement of these tion with a governor and its valve and with parts; neither do I wish to confine myself to the belt which serves to impart motion to said any particular valve or governor, as the same governor, substantially as and for the purpose arrangement, with slight modifications might described. I be applied to valves and governors of different AUGUSTUS BROWN. descriptions. v Witnesses: Q,
What I claim as new, and desire to secure M. M. LIVINGSTON, by'Letters Patent, is- O. L. TOPLIFF. i
