Description

J. ELLIS. THROTTLE VALVE.
Patented Mar. 2, 1915.
JOHN ELLIS, OF SALEM, MISSOURI.
THROTTLE-VALVE.
Application filed June 8, 1911.
To all whom it may concern:
Be it known that I, JOHN ELLIS, a citizen of the United States, residing at Salem, in the county of Dent and State of Missouri, have invented certain new and useful Improvements in Throttle-Valves, of which the following is a specification.
My invention relates to improvements in throttle valves having a sliding piston for controlling the passage of steam from the boiler to the engine cylinder and has for one of its objects to provide means for quickly turning the same off and on.
Another object of my invention is the provision of means for proper adjustment of the steam needed to operate the machinery and to maintain the valve adjusted.
Another object of my invention is the provision of means by which the time necessary for starting and stopping the engine is reduced.
Another object of my invention is the provision of means for reducing the friction in the valve while being operated.
My invention will be described in detail hereinafter, and illustrated in the accompanying drawings, in which,
Figure 1 is a side view in elevation of a valve casing employing my improved valve; Fig. 2 a vertical central sectional view; Fig. 8, a cross section on the line 33 of Fig. 1; Fig. 4, a bottom plan view of a cap plate for the casing; and Fig. 5, a bottom plan view of the packing nut.
In the drawings, similar reference characters will be used to designate corresponding parts throughout the several views.
My improved valve comprises a casing 1 extending upwardly from the steam passage 2 and having its interior formed with a triangular bore 3 in which is mounted a triangular valve piston 4 adapted to open and close a steam passage 2 as heretofore described. The valve stem 5 secured to the valve piston 4 has a link 6 pivotally secured to its upper end that is in turn pivotally secured to the operating lever 7 fulcrumed on a link 8 pivotally secured on ears 9 eX- tending from a cap plate 10 of casing 1.
Specification of Letters Patent.
Patented Mar. 2, 1915. Serial No. 632,097.
11 indicates a segmental rack mounted on the casing 1 and cap plate 10.
12 indicates a pawl pivotally mounted on lever 13 fulcrumed on lever 7, and having a rack face adapted to engage the segmental rack 11 to hold the lever 7 in adjusted po sition.
14 indicatesa block of pawl 12 and slidably mounted on the lever 7 by means of a stem 16 extending therethrough and having a spring 17 mounted on the extended end thereof and engaging said lever 7. This structure holds the pawl 12 in engagement with the segmental rack 11 when pressure on the lever 18 is released.
18 indicates a packing nut mounted on the stem 5 of the valve 4 and having an annular extended portion 19 that cooperates with an annular socket 20 in the upper surface of cap plate 10, the purpose of said packing nut being to hold a packing gland in said socket when desired.
In operation, it will be apparent that the engaging the stem 145 flow of steam through the steam passage 2 may be quickly and effectually controlled by the engineer by simply moving the lever 7 up or down as the case may be, the piston 4 being adjusted thereby to open and close the passage to any extent desired for the most effectual operation of the engine.
Having thus described my invention what I claim is:
In combination, a valve casing having an open end, a valve in said casing, a closure for said open end, a stem on said valve projecting through said closure, a toothed curved bar secured at its lower end to said closure and to the adjacent portion of said casing, means connected with said stem for operating said valve, and means on said operating means adapted to cooperate with the teeth of said bar to lock the valve in adjusted position.
JOHN ELLIS.
