IMPROVEMENTHIN VALVE ARRANGEMENTS FOR LIQUID-METERS.

Specification forming part of Letters Patent No. 119,364, dated September 26, 1871.

To all whom it may concern:

Be it known that I, JULIUs J oNsoN, of the city, county, and State of New York, have invented a new and useful Improvement in Valve Arrangements for Liquid-Meters and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing forming part of this specification, and in which--` Figure 1 is a view in isometrical perspective of the exterior of my improved valve arrangement; Fig. 2, a longitudinal section taken as inldicated by the line .r ao in Fig. 3, which is a transverse section through the 'line y y. Fig. 4 is a horizontal section of the lower valve-box or case,

and Fig. 5 an outside end view.

Similar letters of reference indicate corresponding parts throughout the severall figures of the drawing.

This invention consists in a combination of a main valve or a series of valves in one, thrown by direct action of the liquid through the agency of a small valve having a positive motion, when the whole is constructed and arranged substantially as hereinafter described, and whereby a quick and most efficient action is obtained for the meter and a durable and easy action secured for the valves. i

Referring to the accompanying drawing, Arepresents a chest or case divided by four partitions, b, into iive separate compartments marked, re-

spectively',c c', d d', and e. These compartments' are connected with each other by means of openings inthe partitions, thatare faced oft' so as to form seats for valves f, which serve to open and close said openings. These valves are clamped between collars upon a rod, g, which connects two oppositely-arranged pistons, h hf, fitted to work in cylinders fifi at the ends of the chest. The two outside compartments c c are connected by a passage, k, with which the discharge-pipe!l communicates. The case A is closed in part by a cover, m, which carries a small valve, n, that is oscillated to control ports or passages o o and p p', whereby it is made to act as a four-way cock. One, o, of these ports communicates with the central compartment e with which the inlet-pipe qv connects. Another, o', of said ports connects with an outlet-port, r, that communicates with `the outlet-passage k, and the other two ports or Vpassages p p connect with the cylinders i t" at the back of the pistons. The ends of the case A are closed by covers s s. rlhe compartments d gh the case. Instead of four valves, f, as shown, three will suffice by making the central one of the thickness of the two middie ones and of their intervening washer or co1- lars. Said valves and the pistons h h are so adjustedand fitted that, as the pistons are reciprocated, the valves open and close alternate openin gs in the partitions b. From this description and by reference to the drawing it will be seen that7 by reversing the pressure of the liquid on the backs of the pistons h h, that is between them and the covers s s, which is eii'ected by changing the position of the valve a relatively to the ports o o', the valves f are shifted and made to open alternate openings in the partitions b,which previously were closed, and to close other of alternate partition openings that previously were open. This valve arrangement is equally applicable to piston and diaphragm-meters, but for convenience of description it maybe assumed here to be applied to a piston water-meter. It is secured to or over the cylinder of the meter by means of bolts passing through lugs u u, and so that the compartments d d connect, respectively, with opposite ends of the meter-cylinder. Supposin g the position of the valves to be as represented in Fig. 2, water is admitted through the pipe q -into the central compartment e, from thence by an opening in one of the partitions into the compartment d, which conducts it to one end of the n'ieter-cylinder, all as indicated by arrows. 'Ihe water also passes through the port o in the cover on the one side of the valve u, and through the passage p, and acting upon the back of the piston h shifts the valves f to the position shown in Fig. 2, causing said valves or certain of them to close the openings in the partitions b b. The water passing into the meter-cylinder through d operates upon the meter-piston and forces out the water on the opposite side of said piston previously received from the compartment d, and causes it to be expelled into said compartment, from thence through the opening in the one partition b into the compartment c', and out by the passage k to the discharge-pipe L. Immediately, however, before the meter-piston completes its stroke it is caused to shift, by means of suitable mech anism ,the small valve n to the position shown for it by dotted lines in Fig. 2. vThis reverses the pressure on the pistons 7L h, and causes the valves f to be shifted in zt reverse direction, so as to change the action of the 1neter-pisto11,as required. The Water used for shifting the main valve or valves j' is delivered by the port r into the passage k, and from thence to the dischargepipe l.

Whitt is here claimed, nd desired to be secured by Letters Patent, is-

The Within-described valve arrangement for liquid-meters, composed of aY series of valves, f, controlling a series of compartments, o cf, d d', and e, :md operated by pistons h h' by the direct action ofthe liquid, in combination With the valve u, having a positive motion, and ports or passages o o', jo p', r 7c, and inlet and outlet-pipes q l, substantially as specified.
