VALVE..-
SPECIFICATION forming'part of Letters Patent No. 608,342, dated August 2, 1898.
Application filed January 21, 1893. Serial No. 459,045. (No model.)
' T at whom it may concern:
Be it known that I, JAMES F. MOELROY, a citizen of the United States, residing in the city and county of Albany, State of New York, have invented a new and useful Improvement in Valves, of which the following is a specification.
My invention relates to improvements in Valves adapted for the regulation of the admission of steam into a steam heating apparatus; and the objects of my invention are to provide a valve so arranged that the steam may be caused to enter in very minute quan-. tities, which quantities may be gradually ing,
creased by the operation of the valve, and also to prevent the cutting of the valve-seat. I attain these objects by means of the mechan ism illustrated in the accompanying drawings, in which- Figure 1 is a section showing the valve partly open. Fig. 2 is a section along the lines 1 1 on Fig. 1, showing the valve closed. Fig. 3 is a plan of the hollow cylinder 0, taken from its lower end; and Fig. 4 is a section of the hollow cylinder 0.
Similar letters refer to similar parts throu ghout the several views.
The valve Aisprovided with a valve-stem B, suitably mounted and which may be ar-- ranged in an oblique position, as shown in Fig. 1; but I do not limit myself to this position.
On the valve-stem B, I arrange a valve-disk b, and at the end of the'valve-stem, below the valve-disk b, I construct a hollow cylinder 0. The valve-casing is bored out at D to receive the hollow cylinder C as a piston. The hollow cylinder 0 is provided with cuneiform openings d on each side thereof, making four in all, three of said openings extending from thebottom of the cylinder to very near the top. One of the openings d Iusually make longer than the others-that is, extending to nearer the top of the cylinder -as shown in section in Fig. 4 and also in Fig. 1.
WVhen the valve-stem Bis tightly closed, the disk I) fits closely in its seat, the hollow cylinder 0 finds a seat within the opening D, and the steam is completely shut off. By opening the valve the steam entering through the pipe F will fill the hollow cylinder 0 and find vent through the apex of the port 61, allowing the steam to enter the valve A in very minute quantities. By continuing to lift the cylindenO the opening is increased and a 5 5 larger port is found at d and a verysmall opening at (Z d d. Thus the entrance of the steam may be very easily controlled and such quantities only admitted as is advisable.
When the valve-disk is nearto its seat, but very little steam can flow through the small portion of the opening in the Valve-casing,and
hence no cutting would take place at the seat itself.
WVhen it is desired to get the full flow of 65 the valve, it is evident that it would be simply necessary to open it to its full extent.
It is noticed that I have two valves in series operated by means of a common stem, which I gives a graduated opening through triangular ,or equivalent ports in a cylindrical valve.
valve-stem a very small discharge of steam may be emitted through the valve, thus mak- 8o ing a very quickly-operated valve.
My valve is especially applicable in carheating apparatus, where it is desirable first to obtain the full flow of steam in heating up the car and afterward to throttle it, so that little steam is admitted.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. In a valve, the combination of a casing, a valve-stem and means for operating the 0 same, two valves arranged to be operated thereby in series, one designed to shut off absolutely, the other designed to give a constant but graduated flow, substantially as described and for the purpose set forth.
2. In a compound valve, the combination of a casing, a valve-stem working therein, a valve-disk-operated thereby designed to open and close absolutely, a cylindrical valve ing to and from said casing, so arranged that adapted to be simultaneously operated by the the valves operate in series, substantially as same stem and capable of movement in a cordescribed and for the purpose set forth.
responding aperture in said casing and being JAMES F. MCELROY. 5 provided with ports through its sides so ar- \Vitnesses:
ranged that iluid is throttled gradually, but EDWIN A. SMITH,
not entirely shut off, and passageways lead- WILLIAM 1. EDDY.
