`lrnPRcSyEMENT |N METERS.

Specification forming part of Letters katent No. 159,143, dated January 26, 1875; application filed December 14, '1874.

To all whom it may concern:

Be it known that I, WILLIAM R. BAKER,

` of Chicago, in the county of Cook and State V,of Illinois, have invented certain new and useful Improvements in Meters, of which the following is a specification:

My invention relates to that class of meters which -are adapted to the measurement of fluids, such as gas and water, or other liquids.

A The improvements claimed will hereinafter be set forth.

In the accompanying' drawings, I have l shown an apparatus embodying all my improvements. Obviously some of them might be used without the others, and theI details d of construction be modified in some respects I ,without departing from'` my invention.

l Figure his 'a view, partly in lelevation and partly in section, with portions of the casing and cylinder broken away, and Fig. 2 a plan view, partly in section, with the top of the casing removed.

A tight metallic case, A, is constructed with a removable portion-in this instance one sideto allow access to the interior of th`e casing. A cylinder, B, is mounted in thecasing. The

heads l) b'. are detachably secured in placein.

this instance, by means of through-bolts C .passing through the flanges of the heads and nuts c. Inductionpipes D D', connected with the suppTy-pipe orreservoir containing the -Iluid or liquid to be measured, enter the casing and lead into the'cylinder through its' heads. Eduction-pipes E E' lead from the lcylinder by the sides of the inlet-pipes D D'.

These inlet and outlet pipes are shown`,'in v"this instance, as' entering the cylinder in pairs Aat its ends, one inletand one outlet pipe communicating with the cylinder at either end through a single pipe, near the bottom of the cylinder. In Fig. 2 these forked pipes are shownvin plan and in section. e

A piston-head, F, is tted in the cylinder d B,and has an annular grooye in its periphery,

as usual; for packing. The piston-rod F' passes through the cylinder-headv b, and has iixed on its outer end au arm, f. The free end of this arm is provided with a pin on its inner side, which works in a guideway,'j", supported in the casing in any suitable way,

4 as the piston reciprocates. Cylindrical valves l or cocks G G', similar in general construction,

work in the forked pipes constituting the inlet-pipes D D' audoutlet-pipes E E'. Each of these valves is provided with two Ways or openings, g y', at right angles to each other, those of G' being shownin' Fig. 2 in section.

The opening g is in the inlet-pipe, and the l other, g', 'in the outlet-pipe. The opeuiug's or ways of the valve G are, the reverse of those in G', the inlet-opening g in G being at rightv angles to the corresponding way` in 'G'and the outlet-opening g' in the valve G at right angles to the outlet-'opening in the valve G' By this construction, when the valvesf'a'yl moved simultaneously in the same direction,

they are shifted so that the outlet-opening at one end and. the inlet-opening at the Aother =end of the cylinder', are brought in line''v'itlrL their pipes to open communication from the cylinder at one end, and to it at the other, the

which are pivoted to the opposite ends of par-J allel bars, which constitute a guideway, I, for

. an oscillating lever,J, which acts first on one end andthen on the other end of the guideway as it works in it, rockin g' the valves first to one side and then tothe other simultaneously. i Instead of parallel bars, a single slotted or grooved bar might lbe used for this vguideway I. v The oscillating lever J is pivoted at its lower end to a support, J', suitably ix'ed to the casing, while'its upper or free end is controlled in its movements -by thevalve-connccting guideway I.f A rod, K, is pivoted at one end to the lever J, as at k, and its opposite end has a slot, K', in which works a pin, k', on the end of the arm f, fast to the piston-rod. l A

lever, L, is pivoted at V'one end, as at l, to a support or projection of the casing, and has a weight, L', attached to its opposite vend.

A spring, secured at one end to the lever and at the other to the casing,'might be substituted for the weight. l

The lever, it will be seen by reference to Fig. l,-isprovided with a projection orpoint, Z', on its under side or edge, and is curved on both sides of this point. A roller, M, secured in'the slotted lower end of the lever J, works against vthe under side of the vibratin g lever L as the lever J oscilla/fes on its pi-vot=. The slot-in the lever J serves as a guide to prevent displacement of the lever L. A pawl, N,

`pivoted to the lower Vpart of the oscillating lel ver, engageswith aratchet-Wheel, O, turning on or with-a stud or spindlein the support J..

As the lever oscilla-tes its pawlA moves the wheelv by means ot' the ratchet-teeth,.and by a suitable train of gearing, outside the casing, connected with the spindle of the ratchetwheel, (whichvmight pass through the side of 'the casein a suitable stung-box,) registers theamount of liquid or fluid passed through.

the cylinder, its capacity being known.

In operation, the parts being in the position lshown in Fig. 1, the Water, gas, or other substance enters the measuring-cylinder vby the induction-pipe D', through the way g in the valve G', and by its pressure moves the piston F toward the opposite end of the cylinder,

forcing out, (if the meter haspreviously been in operation,) through the eduction-pipe E, whose Way is open, and the way in the inlet D closed, the contents ot' the previously-filled' cylinder, which empties into the casing. Slightinglever by the piston through its rod,'thevl arm f, and the slotted rod K connecting the oscillating lever and the arm f. The quick movement thus imparted to the valve-connecting guideway I, by the Weighted vibrating lever L, acting, by its curved-pointed under side, on the oscillating lever, instantly reverses the positions ofthe valves Gr G', opening the outlet E and inlet D, and closing the outlet E and inlet D. .The contents of the cylinder, which was filled at one end as it emptied at the4 other, now flow from E', and

the piston is moved to force out the contentsv of the cylinder before it, bythe entrance of the gas or water under pressure at D, and the above-described operation is repeated indefinitely. y Y

As the lever J oscillates, tneNqu'autity'of gas, water, &c., which passes through the cylinder is registered through the ratchet and pawl, and suitable indicating mechanism on the outside of theca-sing. A pipe, P, leading from the casing, connects with suitable ser vice or distributing pipes, by which to conduet the contents of the case to the desired `points.

For measuring liquids the caseshould have an air-chamber to insure a constant flow from* the pipe P during the operation of theimeterf..

The slot in the arm K admits of the quick movement ot' the valve-connecting lbars or guide I, to shift the valves at the end of the., pistons stroke, and prevents any undue strain onthe arm j' or its pin k', upon which the v slot slides, leaving the pin in the proper position, after shifting the valves,.iirst at or'- near one end of the slot, and thenl at or near the other end, to act on the levers on'the return stroke of the piston.

I claim as my invention- 1. The combination, with a measuring-cy1 inder, ot' forked pipes at its ends, constitutingl inlet and outlet pipes, two-Way valves Work- .ing i'n said pipes, and the connected valvef cranks, substantially as and for thepnrpose setgforth; l

2,. The combination of the casing, the cylinder, the piston, the piston-rod, the inletpipe-s, the outlet-pipes, their valves, the valveconnecting guideway, and the oscillating lever Working Ain the guideway to shift the valves, these members being constructed and operating substantially as set forth.

3. The combination of thervalveconneeting guideway, the oscillating lever Working'there in, the piston-rod, the slotted rod pivoted to the oscillating lever' and Worked by the piston-rod, and the vibrating Weighted lever,A

these members being constructed and operat-4 ing substantially as set forth.

,In testimony whereof I have hereunto subl scribed my name.
