SPECIFICATION forming part of Letters Patent No. 610,047, dated August 30, 1898 Application filed July 22, 1896. Serial No. 600,116. (No model.)
To ctZZ whom it may concern;
Be it known that I, MARTIN I-IANNER, a subject of the King of Prussia, German Emperor, residing at Duisburg, Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Out-Off-Valve- Regulating Mechanism, of which the following is a specification.
My invention relates to mechanism for regulating or adjusting the position of cut-0E valves in order to insure the automatic regulation of the cut-off and of the corresponding steam expansion in accordance with the power required of the engine.
My invention is especially adapted for and is here shown in two different forms in connection with Rider valve mechanism; but it is also adapted for use on various kinds of slide and rocking valve mechanism.
The invention consists, briefly, in mechanism hereinafter fully described, and the novelty of which is indicated in the claims, for automatically shifting the cut-off valve by connection with the engine-governor to the point required. by the work at the time being done by the engine, the valve being lifted at the point to which it is set and the shifting mechanism being automatically returned to normal position in readiness to be operated to again shift the valve in either direction when further change takes place in the work being done by the engine.
In the accompanying drawings, Figure 1 shows in sectional elevation one form of .my improvement with such parts of the engine as are necessary to enable the comprehension of the invention. Fig. 2 is an elevation at right angles to Fig. 1.
My invention is here shown as applied to that class of steam-engines having what is known as the Rider valve-gear, wherein the admission of steam is controlled by the governor through the agency of an expansionvalve having oblique ports whose extent of opening is determined by the angular position of the expansion-valve rod. a
The engine Z may be of the represented or other type having the cut-off-lever regulator a pivoted to a fixed support on the frame of the engine and connected to a collar a, which is raised and lowered by the engine-governor. (Not shown.) The lever a is also connected by rods 12 to frame or slide 0, whichis accordingly raised or lowered in accordance with the separation of the balls of the governor caused by changes of speed. Above and be-- low the frame 0 collars or boxes 6 e are located, each connected by rods 6 with arms f f respectively, so weighted that the box 6 is normally maintained in its lowermost position and the box 6 in its uppermost position. Pivoted in the boxes 6 e are angle. levers or detents i, normally held by pressure of springs 'i outward against the Walls of the boxes. Small arms h on said detents are arranged in the path of the frame 0. The toothed bar Z0, pivoted to the arm Z of the cutoif or expansion slide, passes through the frame 0 and the boxes 6 e and is counter- Weighted at k and held movably to any position to which it is set by an adjustable spring k bearing against the heel of the counter weight arm It will now be seen that when by the action of the governor the frame 0 is shifted from its normal central position upward or downward the said frame strikes against the arms h of the detents 2'. The resistance of the weights f f is sufficient to cause the detents i, when their arms h are so struck, to engage the toothed bar 75, so that the boxes 6 e carrying the detents so struck by the frame 0, are in efiect coupled to the rod 70, and the latter will accompany the movement of said frame and shift the expansion or cut-off slide by means of the arm Z, acting in the operating-rod M-of said slide. The degree to which the engine is filled will then remain unchanged, for although the engine resumes its normal speed and the governor-balls return to their normal position, carrying with them the frame c, the detents 1' during this return movement will slide over the teeth of the bar 70 as the boxes 6' e settle back under the influence of counterweights to the normal position. Only when the frame 0 is moved again from the middle position in one direction or th'e'other by the governor is the expansionslide again acted upon and a corresponding change made in the degree of filling of the cylinder.
Having thus described my invention, the
ICO
following is What I claim as new therein and desire to secure by Letters Patent: 7
1. In a cutoff-regulating mechanism, the
combination of the valve or expansion slide, a shifting device therefor connected to the governor and means norm ally held in position to be operated by said shifting device on motion in either direction to connect said shifting device to the expansion valve or slide to shift the latter and automatically disengage itself therefrom and return to normal position, substantially as set forth.
2. In an expansiongear mechanism for steam-engines, the combination in a shifting device connected to the governor, detents mounted on each side of said shifting device, a toothed member connected to the expansion 15 valve or slide and adapted to be engaged by said detents and means of disengaging said MARTIN HANNER.
