Be it known that I, WILLIAM ROBJOHN, of the city, county, and State of New York, have invented a certain new and useful Improvement on Water or other Liquid-Meters, of which the following is a full, clear, and exact description, reference being'had to the accompanying drawing forming part of this specification, and in \vhich" Figure 1 represents a front elevation of a meter, constructed according to my improvement.

Figure 2, a partly sectional rear view of the same.

Figure 3, a sectional elevation thereof, parallel and in close proximity to the dial-plate.

Figure 4, a longitudinal view of thc prime mover or first driver to the registering motion; and

Figure 5, a transverse section of the valvein connection with its box or case, the direction of the cu'rrent'or'flow of liquid through the meter.

Like letters indicate corresponding parts throughout the scvcrirlfigures.

This invention relates to a meter-for measuring liquids capable of being regulated to measure large or and passages for changing small and specified varied quantities; and the natureof the invention consists in certain combinations of mechanism, whereby the meter is made automatically to stop on the required quantity being measured, with and protection sgainst being started without adjustment of the index. Also, in various combinations of mechanism, whereby the general action or working of the meter is improved,

andleaknge, by dispensing with a stufiing-box to the rccipr-ocating'piston of the measuring-cylinder, is avoided.

Referring to the accompanying drawing, A represents the induction pipe of or to the meter, and communicating withs-valve-box, B, so which C is the cduction pipe, and DI) the pipes or ways to the upper and lower ends of the working or measuring-cylinder E. The valve F is of the butterfly order, and as it is reciprocated to and fro or oscillated by its shaft a, serves to alternate in a rapid and easy manner. the indcution and -.eduction pipes A and C, with the pipes or passages D or-D, to reverse the action of the piston G in the cylinder E, and which form of valve is preferable to in four-way cock, having contracted openings through it and v controlling said pipes or passages. The piston G has or may have its rod 6 slotted at or near its top to secure the timely operation, in it's reciprocating movement, of a lever, H, that is arranged within a water-tight box or case, I, in communication with the cylinder E at its top, thereby avoiding the necessity of a striding-box for or to the piston-rod, and by making the fulcrum-shaft c of, the lever Hot a conical or taper form, where it fits through the box I, securing, by the pressure of the-fluid, a water-tight fit of said shaft. Connected with the shaft 0 on the outside of the box or case I, is a lever J, to which is pivoted a rod, K, that is in gear through a slot, d, pin e, and regulating-screw f, to adjust the throw, with a lever, L, reciprocated intermittently or at intervals by the connections herein described, at or towards thd close of each stroke of the piston G. This lover L is attachedto a fulcrum-shaft, g, and has jointed to it at its outer end a rod, {1, which, by means of a crank or arm, 1', connected with the valve-shaft, reverses the position of the valve F to automatically, or by the operation of the piston G, vary the induction and eduction to'and from the upper and lower ends of the measuring cylinder. The gear of the rod 1:, with the arm a of the valve, is'a slotted one, so that it is not till after the lever L has been suddenly shot at or towards the close of the piston's stroke, that the valve F is reversed in a sudden and positivemanner as usual, and well understood to he neccssiiry in other water or liquid-meters. This sudden shooting of the lever L is or may be efi'ected as (follows: Fast to said lever is a doubled'nclincd bar or plate, M, forming a culminating point at the centre of its one edge. Bearing against this double-inclined bar is a rollcigj, carried by an arm, is, furnished withprojections or cars l, and pivoted to clever, N, that is borne or pressed forward by a spring, 11', so that in the up or down motion of the lever-L, and on the culminating point (iicentre of the double-inclined bar, passing tlienxial line of the roller 3', which occurs when the piston in the measuring-cylinder arrives at the end of its stroke, the roller, borne forwards by the action of thespring m, presses on the inclined surface or edge of thcb'ar M, to suddenly shoot the lever L, and so reversc the action of the valve E. Connected with the fulcrum-shaft y, of this ievcr L, is a lover or arm, 0, that carries at its outer end a slotted bar, 1?, having studs n, n'hichgear, in the manner of s mangle-rack, with a double toe, Q, hung on a shaft or spindle, q, in such manner as that, on each throw, up or down,- of the bar P, by. the operation of the lever L, said toeand its shaft are rotated half a circle, and on the following throvv, up or down, of

. eases 2 the arm P, the motion of the shaft and its toe continued the other half of the circle. This serves-to operate the first driver of the registering motion or gear, which driver is composed of or by the body of the spindle q, slotted at its centre, and formed into teeth or studs r, on either side, and whichgear with a pinion, R, are secured each throw to a perfect lock with said pinion, and the double toe adjusted to its proper position by a spring, S. The spindle oi the pinion R carries a one-toothed disk, T, which gears oncein each revolution with a wheel, U, while thepinion Ritseli', in addition to gearing with the teeth 1' of the driver, also gears with a spur-wheei, V. The spindles or shafts of the pinion R, and. wheels U and V, carry the indicating fingers a tea, on the dial, and which system of indicators may be multiplied to any desired extent by the addition of appropriate gear. to effect the'regi'ster, as is well understood by those acquainted with meters generally. The

shaft of the wheel V is made capable of a longitudinal sliding movement, so as to lock or be thrown out of gear with the pinion R. Said wheel may be thrown out of-gear by means of a spring, 11, pressing on the inner end of its shaft, and be held in gear by' a pin, 10, projecting from the rear face of the dial, and bearing against the outer rimof the wheel V, until, during the rotation of the latter, a hole, racemes ,opposite said pin, when the springv shoots the wheel out of gear, and locks it by the projection of the pin w through it. By this means the meter may be made to pass or measure any or a varied specified quantity, and then to automatically cease, by turning the dial finger-connected with the wheel V to a suitable point or figure on the dial, so as to bring the holes: a given distance from the pin in, such distance in the circle or rim'of the wheel from the pin 10, varying accordingly as it is required to arrest the action of the meter to a small, large, or any intermediate quantity of liquid required to be passed and measured or. registered.- To effect the arrest of the general as well as the registering action of the meter by the shooting of the wheel V out of gear and into lock with the pin- 10, the longitudinal movement of the spindle of said wheel is made to control a stop-cock, W, on the educ-.-

tion pipe, so that not only is the general action of the meter stopped by arresting the flow, on the wheel V being shot out of gear and locked, but the cscapeof liquid remaining in the measuring-cylinder arrested, This is accomplished by means of a clutch-lever, y, operatedby the longitudinally sliding spindleof the wheel V, and connected with a rock-shaft, X, that carries una'rm, .1, which, on the wheel V being shot out of gear, acts upon an upper shoulder, a, to a vertical sliding-rod, Y, that,.being depressed, operates, by a lower collar, 6, to trip a spring-borne catch-lever, c, the inner end of which is thereby released from loclr'or gear, witlra camshaped formation to or of a hand-lever, Z, that controls the stop-cock W,- and which, on being thus thrown out of lock with tho catch-lever. c, is shot back by the action of a spring, A, to close the stop-cock, nor can this stop-cock lever Z be again locked with the catch-lever '0 and stop-cock kept, open, till said catch-lever is again put into locking position by the setting of the wheel-V into registering gear,when, on throwing the stop-eocklever into lock with the catch-lever, the meter may again be started and-run.

What' I claim as my inrention, and desire to secureby Letters Patent, is-- 1. The combination of the reciprocating piston G, with its rod 12, measuring-cylinder E, water-tight box or case I, and lever H, all for operation together and withoutside mechanism, substantially as specified.

2 The combination, with the shaft 0, ofthelcver H, of the arm J, slotted bar K, lever L, double-inclined bar or plate M, and roller j, for operation together as herein set forth.

3- The combination of the lever O, slotted bar P, provided with studs 1, in mangled rack-gear, with a double toe, Q, and driver q, furnished with teeth 5', essentially as and for the purpose specified. v

4. The longitudially sliding springdiorne wheel V, having an aperture, 1', in combination withs locking stop, w, and geared with a stop-cock, W, for control of the latter substantially as herein set i'orth.

5. The rod Y, operated as described, spring-catch c and stop-cock lover or handle, controlled by aspring,

all for operation together, essentially us and for the purpose or purposes specified.
