Letters Patent No.199,266, dated Jarman/*25M IMPROVEMENT IN LIQUID-METERS.

The Schedule referred to in 'these Letters Patent and making part oi the same.

To all whom 'it may concern Be it known that I, FRANZ WAGNER, of New York, in the county and State of' New York, have invented a new and useful Improvement in Waisen-Meters; andi do hereby declare thatthefollowing is a full and exact description of the same, reference being hadto the accompanying drawings, and to the letters of reference marked thereon. .V

Figure I represents a horizontal section of my improved water-metcr; v

Figure II is a vertical section ofthe valve-chamber and valves;

Figure III .is a vertical section of the cylinders and passages between;

Figure 1V is a section of'the valve-chamber at the line as, Fig. II; and

Figure V isa section ot' the valve-chamber and valve, at the'line y, Eig. II.

Similar letters represent similar parts in all the figures.

This invention relates to a meter for measuring water or any other Huid; and consists ot' two pistons, working in suitable cylinders, connected,through suitable piston-rods, with a double circular valve, which, as the pistons assume their reciprocating motion, by the fluid ,acting upon the same, cause` this circular valve orvalves to rotate, and thereby change the direction ofthe l'luid.v

A A' represent the cylinders, into which the pistons B B' are lit-ted.

These cylinders have the valve-chest C attached to one end. v

The valves D D', with their dividing-disk E, are attached to a common shaft or spindle, F, having, at each end, acrank, a a', attached, to which thepistonrods b b are connected, at an angle'of about ninety degrees, more or less, to each other-.

,'.ihe valves D D'nndthe dividing-disk E, are ground into their respective seats J J in the valve-chest G, and the valve-chest C is arranged withsuitable passageways n n', forming a communication between the inlet or supply-pipe G and the interior oi' the valves D 4 and D', as well as with suitable passage-ways m m',

forming a communication between said valves and the discharge-pipe H; and further, this valve-chest C has suitable passage-ways 't c arranged, connected with the passage-ways ur fw', forming a communication be-` tween the ends of the valves D D' and the ends ofthe cylinders A A', behind their respective pistons, while the outer ends of said valve-chest C are in direct com munication with the forward ends of the cyli-nders A. A by the passages p p', and through which said pa.,- sages p p', the piston-rods l) b' pass, to connect with the cranks a a', to give the necessary and required ro- .lhe registering-apparatus may be placed on either end of the valve-chest, and may be operated by a suitable lever, connected with the crank-pin of the cranka or a.

The valves D and D' are constructed with two chambers, fr r and ss', respectively, each of' which connects' either with the opening in communication with the Y the other end ofthe passageinto the cylinder, accordin g to theposition of said valve.

When the pistons occupy the position .represented in the drawing, the fluid before the piston B will pass through the chamber r, in the valve D, into the passage m anddischargc-pipe H, whileI the fluid from the supply-pipe 'G will pass, through the passage-way a, into the chamber c" in the valve D, and through the end of said valve into the passage 1:, through the passage w, into the cylinder A, behind the piston B, acting upon the same, so as to propel said piston in the direction indicated by the arrow. At the same time, the uid from the supply-pipe G passes through the passage nl', through the chambers in the valve D', through the end of said valve into the passage c', through the passage'w into the cylinder A', behind the piston B', acting upon the same, so as to propel said piston in the direction indicated by the arrow, and, at the same time, assist the passage of the crank a, to which the pistou B is connected, over the cent-rc, while the duid before the piston B will pass through the passage p',- the chamber s in the valve D', through lthe passage 'm' into the discharge-pipe H.

When the pistons reach the end of their stroke, the. position of the respective valves is thereby changed, and the iluid passes in the contrary direction.

By these means, a fluid-meter is obtained, wherein the valves are self-operating, without the lassistance of any extra lever or springs, and which operates with very little pressure, and independent of any head undervwhich the tluid enters to or discharges from the met-er. All the friction created by the working-part is easily overcome, and no fluidcau pass through the .meter unless lit is measured.

This meter may be placed in the grounddoor of a. building, and it will indicate thc water drawnfrom apy of the faucets in the house.

What I claim as my invention, and desire to secre by Letters Patent, is y 1. The arrangement ot' the rotating valves D D', connected, through suitable rods `b l1', with two reciprocating pistons B B', and operating in the manner and for the purpose substantially as described.

2; The rotating valves. DD', with their respective chambers r 'r' and s s', in combination with the passage-ways n n', m m', and 'u e', and communicating, through the passages p p'and w w', with the endsoi the cylinders A A', the whole being arranged substantially as and for thepurpose set forth.
