'ro ALL PERSONS To WHoM THESE 4PRESENTS SHALL COME;
Be it known that I, REUBEN'K. .HUNTOOIL of Boston, inthe county-of Suffolk, and State of Massachusetts, have made a new and useful or improved Governor for Engines ;v and do `hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure' l is a front elevation of it, as applied to the throttle-valveof a steam lengine.,.
Figure 2 is a vertical and transverse section of it.
Figure 3 is a horizontal section of the propeller cistern.
Figure 4 is a longitudinal section; and
Figure 5, a transverse Section ofV the throttle-valve and its case.
Figure 6 is a top view and Figure 7, an edge elevation of the propeller. p
In such drawings, A is a close cistern orvase, havingashaft, B`, extending down 4into it axially, and into a tubular bearing, C, arranged on and so as to project upward from the bottom ofthe said cistern. Fixed to the said shaft, and arranged within the cistern, is a screw-propeller, Outside of the outer edges of the blades of snch propeller, the cisteru is provided witha series of vertical ribs or'wings, a da, which are projected from its inner surface, theybeing to aid in preventing the liquid used inthe cistern fromA being revolved therein by the pro'- 4peller while it may be in rotation. There is a projection, b, on the outside of the tubular bearing O. In this projection, and leading into the space lwithin the bearing, is a passage, c, to which a stop-,c ockJ, is applied. The passage c opens a communication between the interior of the cistern and the space immediately beneath th'e shaft B, the stop-cock being to diminish this communication, as circumstances may require, in order to let flowl into and out of the said spacevmore or-less of the liquid in the cistern, While the shaft B and 4the propeller may be in revolution. In thc upper part ofthe cistern A, and 'surrounding the shaft B, is a tapering deilector, e, which, while the shaft is in revolution, operates by deflecting the liquid throvvn upward by the propeller, to prevent the escape of such liquid through Vthe shaft-hole or bearing in the top of the cistern. The said 'shaft `B has a long gear, g, tix-ed on it. The said Agear engages with another gear, L, fixed on a shaft, z', which is revolved a belt proceeding from a pulley driven by the engine, to be regulated by my improved regulator. A-lever,`E, jointed to a link, F, which, at its `lower end, is jointed to a standard, G, bears on the top ofthe shaft B, such shaft having a. spherical pivot or head, z', to enter a semi-spherical socket made in the lever, and provided with an oiling-hole, k. From the lever E a connecting-rod, H, (formed with a shoulder, K, and providedwith a series of weights, I, I', I, to rest thereom) depends, and is jointed to an arm or crank, L, extending from the shaft M, of a throttle-valve, N. This throttle-valve is a hollow cylinder or conic frustum, open at one end and closed at the other, the closed end being fastened to the shaft M, which runs through a stning-box, O, of a val-vecas'e, P. The said'valve works in a tubular seat, R, which is surmounted by an annular passage, S. A conduit, 'T, leads out of the said annular space. Another conduit, U, leads out of the open end of the valveseat, the same being as represented;
Three rectangular openings, k 7c 7c, made through the valveradially, and at equal distances apart, operate with three l openings, ZlZ,'formed through the valve-seat. One'side of each of the openings l is crowned or arched, as shown at m, the same being to let the steam gradually into the opening s. Steam from a boiler is to pass into the annular space S, and, after passing through the valve, is to go into and through the conduit l, to the valve-chest of the steam engine. On the propeller being put infrevolution within the cistern A,illed with a liquid, it will rise in such liquid, and force the shaft B upward, and cause it to raise the lever E. The valve will be moved in the meantime so as to diminish the passages for the ilowage of steam through it. 'As the speed of the propeller may be increased by the engine, the steam passages of the valve and its seat Vwill be contracted; but on decrease of the speed, the propeller will fall in the liquichand the valve passages 'will be enlarged. .Thus the` amountof steam required to Work the engine, according 4the duty it may have to perform, will be regulated by the governor. The bearing C, and its passage c, provided with a stop-cock d, and opening intro the liquid space of the cistern, enable us to apply to the shaft B a force to` resist either its rise or its fall, -or'that of the propeller. By such means applied'to the shaft and cistern of the propeller, we can control the rise or fall of thepropellen'as circumstances may require; for, as we may turn the stop-cock so as to interrupt the iiowage of -liquid into the chamber beneath the shaft B, we shall bring to operate on the shaft more or less atmospheric pressure, and more or .less friction of `the liquid in passing the cock, to resist the upward movement of4 the y raft. The descent of the shaft will be impeded by the liquid drawn .into/the vacuum chamber, such liquid aking its escape slowly through the cock.
I claim the combination of thebearing C, its passage e, and stop-cock d, with the shaft B, the propeller D, id the cistern or vessel A, arranged as and for the purpose set forth. v
I also Claim the combination and arrangement of the deilector e, with the eist'ern A, the shaft B, and the ropeller D, arranged as and for the purpose set forth.
I also claim the Vcomb'ir'xation.and arrangement of the wings a, with thev cistern A, the shaft B, and propeller "L arranged as set forth.
