SPECIFICATION forming part of Letters Patent No. 300,468, dated June 1'7, 1884.

(No model.)

To a l! whom it may concern:

Be it known that we, CHARLES S. HAsKnLL and XVILLIAM B. FLEMING, of the city of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Valves, of which the following is a full, true, and exact description, reference being bad to the accompanying drawings.

Our invention relates to an application of the auxiliary-valve principle to valves adapted to be opened and closed by hand or by mechanism; and it relates more particularly to machines in which a. secondary valve is so combined with the main valve as that the operation of said secondary valve will serve to close or to open or to open and close the main same.

valve; and it consists in the specific constructions by which this is effected, and which will now be described.

Our invention will be readily understood from the accompanying drawings, in which Figure 1 represents a cross-section-of our valve, showing all the parts; and Fig. 2 represents a sectional view of a modification of our invention.

Similar letters refer to similar parts in all the drawings.

A represents the inlet-pipe, and B the outletpipc.

Our valve, as shown, is particularly applicable to a water-valve.

G represents the main valve.

\Ve will describe first the valveshown in Fig. 1. The main valve is pierced with ports D and F, of which. D communicates with the water-pressure and Fwith the chamber above the main valve. Within the main valve is the auxiliary valve G, operated by the stem l-i. This auxiliary valve may be raised and lowered by screwing the handle H. The

lower part of the main valve has a pipe connecting with it and delivering through the outlet E to the atmosphere or waste. The main valve and its connections can move up an d down vertically. The operation of this valve can now be readily understood: In the position shown the water-pressure entering by the pipe A passes through the passage 1), past the auxiliary valve; thence through the passage F into the chamber above the main valve, thereby seating the main valve firmly and closing the If the handlel l be raised by unscrewand provided with suitable seats, as is clearly 6 shown in the drawings.

In Fig. 2 an auxiliary thrceway cock is shown at L. As shown in the figure, the wator-pressure passes directly by the passage M into the chamber above the main valve 0, and thereby seats the same 5 but if the threeway cock is turned a quarter of a turn, the outletpassage E will be put in communication with the chamber above the valve, and the water therein will be permitted to escape, when the pressure beneath the valve will force it upward and open the same. Some features of this case are shown in our application filed March 10, 1883, Serial No. 87,731; but we do not herein claim anything claimed in said application.

WVh-at we claim as our invention, and desire to secure by Letters Patent, is

l. The combination, with an inlet-pipe, of a main valve arranged directly in the pipe and an auxiliary valve in a valve-opening communicating with the inlet-pipe, the arrangement being such that the main valve is operated by the direct pressure of the water in the pipe, and is closed by the pressure of the water controlled by the auxiliary valve, as set forth.

2. The combination, with an inlet-pipe, of a main valve arranged directly in the pipe, and an auxiliary valve consisting of a three way cock in a channel communicating with the inlet-pipe, the arrangement being such that the direct pressure of the water operates to open the main valve, and the pressure controlled by the three-way cock operates to close the same, as set forth.
