IMPROVEMENT IN LIQUID-METERS.
TO ALL WHOM IT MAY -CON CERN:
Be it known that I, JosHus` MASON, of Paterson, in the county 'of Passaic, and State of New Jersey, have invented a new and useful Improvement in Water or other Liquid-Meters, of which the following is a full, clear, and exact description, reference being had lto the accompanying drawing, forming part of this specification, and in whicb- 4 Figure 1 represents a central longitudinal section of a meter constructed in accordance with my improvement.
'Figure 2, a longitudinal interior view of the opposite half of the-valve-case to that shown in iig. 1.
Figure 3, a face viewV of the inner end of tbe valve-case, with the. device for operating the primary valve attached; and
Figure 4, a transverse section of the valve-case, taken as indicated by the line z a: in figs. 1 and 2.
Similar letters of reference indicate corresponding parts.
My invention relates to that description of liquid-meters in which a reciprocating piston is used within a measuringcylinder, and made to operate a primary valve, that serves to control the passage of the liquid, to operate a Secondary valve, for the purpose of reversing the action of the piston within the measuring-cylinder or chamber; and my invention consists in a novel and advantageous end-arrungement of said valves with their chambers, relatively to the measuring-cylinder; also in a peculiar construction of the valves, of a multiplied head or disk-forni, in combination with the passages which they control; and in an arrangement of certain of the ports and passages, whereby not only is the secondary valve kept shut by the pressure of the ilnid, in a static relationship or action upon it, but also by the iiow of the liquid through it; likewise, said invention further covers a chain or link-like pulling-connectionand thrusting-action of the piston in the measuring-cylinder with and on theprimary valve, and tubular-stem construction to the iatter, to give to the valve a balance character, as it were, that is, to relieve it o'l objectionable end-resistance or pressure.
Referring to the accompanying drawing, A represents the measuring-cylinder or chamber of the meter, and B its piston, arranged to reciprocate ther-ein, by the pressure of 4the Water or other liquid to be measured, alternately acting on opposite sides or faces of it. G is a rod attached to the piston B, and which may be used to work any suitable indicator for registering the amount of liquid passed through the meter.
The outer or back end of the cylinder A is closed by a'lid or bonnet, D, while its inner or fro-nt end has connected with it, or bolted on'tc it, a valve-box or caso, made, nay, in halves or sections, E E', bolted or otherwise secured together, and constructed to form cylindrical valve-chambers, F F', arranged parallel to the axial line of the cylinder A, and which may be closed at their outer ends by a cap-plate, a, while the inner end of the onevalve-chamber, F, may be closed by a plate or disk, b, and the corresponding end ofthe other valvechamber, F, left in open communication at c with the cylinder A. Flanged face-plates or formations, b b', to theiscctions'E E', form a lid or cover to the inner end of the measuring-cylinder.' The one-half, E", of the double-valve case,communicates, by a passage-way, G, with the measuring-cylinder A., on the front or inner side of the piston.B. This passage-way connects, by an opening, d, made in the one section, E', of the valvecase,'with the one or lower valve-chamber F', which latterhas a passage-way and branch, e, that connects, by a lower passage, II, with the back or outer end ofthe cylinder A, in rear ofthe piston B. The valve-chamber F is also connected, by passages, ff and g, with the ctheror upper valve-chamber F, the passage g communieating by a branch, I, with any suitable inlet-pipo, and said valve-chamber F being further connected by ports s s', made in the one valve-case section, E, with an outlet branch, J. I The upper valve-'chamber F has openings z' i', made in seciion E of the valve-case, said openings connecting said valve-chamber with the outlet-branch J.
` Arranged within the valvechamber Fis the primary valve K, made up of disks or piston-hpeads, 7' 7l and lo 7c', attached to a. tubular stem, and working or reciprocating'in a ci'ose manner, to throw its disks or heads jj over and to opposite sides alternately of the passagesff, but not crossing by any of its heads jj and k 7c', the ports or openings z'z", said valve K being thus operated by the piston B, as it approaches and nishes its strokes in opposite directions, and which may be etl'ected as follows: L is a jaw-shaped lever, working on a fulcram, as at Z, and coupling or vgearing at its upper orjaw-shaped extremity, through a. cross-pin, m, with the end of the stem to the valve K, that enters, say, the cylinder or chamber A. Pivoted to the lever L is a stud, M, connected by a chain or chains, N,'with the piston B, on opposite sides of acentral steel disk or block, O. The chains N are of sufficient length to remain slack till the piston B approaches the back end of its stroke, when they pull on the lever L, te throw the valve K to the position represented for it in tlg. 1, while, on the piston B returning and approaching the opposite end of its stroke, the disk or block O strikes the stud M, to shift the f valve K, so as to give its heads jja reversed position relatively to the passages ff. b
P is a secondary and free or independent valve, 'arranged to play or reciprocate within the valvc-chamber F, and constructed with close-tting heads or disks, n n and rr', the disks r r playing-up to but not crossing the passages ff and ports s s', and the disk n crossing alternately to opposite sides of the passage-way or branch e, while the other disk, n, crosses to opposite sides'of the port or opening, d. This valve P may be thusv limited in its throw, by its stem striking the closed ends of its chamber F. I I
As the valves K and P are situated in the drawing, water entering by the inlet I is conveyed by the passage gbetween the heads n and n. ofthe secondary valve P, to the branch. e, and along the passage H to the back of the piston B, to propel the latter to the right, the water previously/supplied the cylinder A at the same time passing oil from or in front of the piston, through the passage-way G and opening d, into the valve-chamber j F, between the heads n and r of the .valve P, and out through the port s into the general outlet J. On the valve K being reversed, which takes place when the piston B arrives'at the opposite end of its stroke, water entering by the inlet I is conveyed by the passage g between the valve-disks n n', and from thence, through the opening al and passage-way G, into the cylinder A, in front of the piston B, while the water in rear of the latter escapes by the passage H, branch e, and through the port s, into the general outlet J'.
The secondary valve P is thus suddenly changed or reversed, to alternate in opposite, directions the flow of water through the meter, and to keep up the-action of the latter by means'of the primary valve K, as itis operated bythe piston B, said primary valve alternately connecting, first, the one passage,f, withthe waterinlet'passage g, and passa-gef with the outlet-port z", to enter water at back of the valve-head r', and passit from in front ofthe opposite head, r, to throw the valve P to the left, and afterwards connecting the passagef With the inlet-passage g, and passagef with the outlet-port z'," to reverse the position of the valve l?.
Though the valves, it willbe seen, are of' what may be termed a balance character, while moving, by reason of the incoming and outgoing water acting on opposite sides of their heads or disks, the hollow stem to the valve K favoringsuch action, so far as that valve is concerned, yet the free or independent valve P, once shot, is subjected to the static' pressure of the wateren .the outer surface of either of its end disks alternately, tor keep said valve in the position to which ithas been thrown; also the water, in passing through said valve, hasA the direction of its curient so established as to aid in producing a similar eiiect of keeping the valve closed to the position it has been shot, by reason of the.relative-arrangement of the passages g e, and *ports or openings communicating therewith. Thus, supposing water to be entering the branch e from the passage g, it, in iiowing obliquely through the valve, acts upon the disk 'n' to keep the valve? shot to the right; or, supposing the position ofthe valve P to be reversed, theentering water, in working its way obliquely through the valve, from the passage g to the opening d, acts upon the disk n to keep the valve P shot to the left. In this way the iow of the water through the valve acts in a direction to which the valve has been last moved, and this, aided by the pressure of the water on the outer end disks r r alternately, as hereinbefore referred to, prevents all shifting of the valve by4 suddenly checking the flow. What is here claimed, and desired to be secured by Letters Patent, is-.- l
1. The combination, with the' measuring-cylinder A and its reciprocating piston B, of primary andi-secondary valves K and P, when arranged for operation in relation to the measuring-cylinder, substantially as shown and described.
2. The primary and secondary valves K and P, formed with disks or heads jj, 1c k', and u n', r r', for I operation within valve-chambers F F', in combination with ports and passagesff, i inlet-passages g, branch l e, passage-way H, ports s a', and passage G, with its opening al, essentially as specified.
3. The arrangement of the Aports or passages which control the ingress and egress of liquid through the secondary vlve, andof the passages in connection therewith, in such manner as that the How of the liquid through thevalve acts on the latter in the same direction as that to which it has been last shot, and so that said valve is kept 'shot or thrown in opposite or reverse positions by the pressure of the Huid on itsropposite heads alternately, substantially as herein set forth.
4. The primary valve K, operated by the piston of the measuring-cylinder, essentially as described, and having an open tubular stem in open communication with the latter, as and for the purposespeoiiied.
