RECORDING MECHANISM FOR WATER-METERS.

S?ECIFICATION forming part of Letters Patent No; 447,594, dated March 3, 1891.

I Application filed February 25, 1890- Serial No. 341,746. (No model.)

To all whom it may concern.-

Be it known that I, HENRY B. \VILLIAMS, of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Recording Mechanisms for Water-Meters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this speciro fication.

My improvement relates to water-meters in which a weighted arm is raised by the pressure of the water acting against a valve inside the receiving-chamber. To the arm is at- I 5 tached a stylus or pencil resting in contact with a ribbon that receives progressive movement by clock-work. The ribbon is lined both longitudinally and transversely, the longitudinal lines indicating increasing quantities 2c of the liquid from bottom to top, and the transverse lines indicating time in hours and subdivisions of the passage of the ribbon. An electrical attachment is also employed for stopping the running of the clock when the z 5 water is not flowing.

In the drawings, Figure 1 is a side elevation, partially in section, of the meter audits attachments. Fig. 2 is a cross-sectionin line x as of Fig. 1.

o Aindicates the receiving-chamber provided with inlet-pipe l3 and outlet-pipe O, the latter provided with a faucet or cook D, by which the flow of water is controlled.

E is swinging valve located crosswise of the chamber and resting in its vertical and closed position against an abutment a. lVhen the faucet or cock is opened, the pressure behind the valve causes the latter to swing open and allows the water to flow around the valve and escape. The greater the pressure of water the greater will be the opening of the valve.

F is an arm rigidly secured to the axis of the valve outside the chamber. This arm is provided with a sliding weight G, which can be adjusted out or in to produce more or less resistance to the opening of the valve.

H is an arm attached to lever F and provided with a stylus or pencil point Z).

I is a flexible ribbon or band wound upon two drums K L, the axis 0 of the latter drum being provided with atorsion-spring d, whose tendency is to wind it up, and therefore un wind the ribbon from the other drum, which runs free. These drums are located at such distance apart as to leave a straight length f of the ribbon of considerable extent between them. The face of the ribbon is marked with a series of longitudinal parallel lines g g g and a series of transverse lines 7L -h h, as

shown. The stylus b rests over the face of the ribbon and in contact therewith, so that as the ribbon is moved longitudinally the pencil will make a mark thereon.

J is aclock of ordinary construction located above the ribbon, and M is a small spindle provided at one end with a gear-wheel i, that engages with a gear 7c of the clock, and at the other end with spur-wheelsl 1, that bear upon the face of the ribbon and against a back plate at of the supporting-frame to regulate the feed of the ribbon.

N is an eleetro-magnet located opposite the clock, and 0 an armature attached to an arm P, which enters the clock and rests opposite the balance-wheel n of the same. The arm is forced in by a spring 0, and in this position it crosses the rim of the balance-wheel, and the latter is provided with a projecting pin 1), which strikes the arm, thus stopping the clock. It rests in this condition when the electrical circuit is open. When the circuit is closed the magnetis charged, the armature drawn back, and with it the arm P, and the clock is then free to run.

0" is a fixed electrode attached to the arm H by a stem 1' and moving up and down with said arm.

5 is another electrode attached to a stems, pivoted at its opposite end to some fixed support and capable of swinging up and down, being stopped in the down movement by a pin to under the stem. When the valve E is closed and the lever F lowered, as shown in full lines, Fig. 1, the electrodes are separated, the circuit is broken, and the clock is then 5 stopped. lVhen the valve is swung out and the lever raised, the circuit is closed and the clock then runs. This occurs only when the water is being drawn through the meter by the opening of the faucet.

IOO

The operation is as follows: The faucet being opened to allow the flow of water, the circuit is closed, and the clock, operating through the spur-wheels Z Z, allows the ribbon to feed forward and be wound up on the spring-drum L, the stylus h at the same time making a longitudinal mark on the ribbon to the extent to which the ribbon is moved. hen the faucet is closed, the valve drops back to its original position, the circuit is broken,the clock is stopped, and the ribbon ceases motion. The stylus therefore makes a continuous longitudinal mark, but at intervals corresponding with the opening of the faucet. The amount of water which passes through the meter is measured by the mark upon the ribbon, a given quantity running through in a given time, and this time being measured by the cross-marks on the ribbon. The greater the pressure from the main behind the valve the greater will be the opening of the valve, and consequently the greater will be the flow of the water. The greater the movement of the valve the higher will be the rise of the stylus over the ribbon. The longitudinal lines g g g on the ribbon indicate different quantities of water, increasing from a lower to a higher denomination as they go up, and consequently as the stylus rises under heavier pressure it tallies with a line of a higher denomination, and follows this so long as the pressure remains the same.

Having described my invention, I do not claim a moving ribbon and a pencil-point registering therewith.

hat I claim as new, and desire to secure by Letters Patent, is-- 1. In a water-meter, the combination of the receiving-chamberA, the pivoted valve E, the weighted lever F, the arm H, attached to the lever and carrying a pencil, the traveling ribbon I, the clock J, provided with a spindle M,

which gives motion to the ribbon, the electromagnet N, armature O, and arm P, which engages with the balance-wheel of the clock, and the electrodes r 5, one attached to lever F and the other to chamber A, as shown and described, and for the purpose specified.

2. In a water-meter, the combination, with the valve-lever F and clock .I, of the electromagnet N, armature 0, arm P,fixed elect-rode r, and swinging electrode 5, arranged to operate in the manner and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
