FREDERICK 'GUTZKOV OF- SAN FRANCISCO, CALIFORNIA.

PISTON WATER-METER.

SPECIFICATION forming part of Letters Patent No. 400,401, dated March 26, 1889.

" v Application tiled November 10,1888. Serial No. 290,484. (No model.)

To @ZZ whom it may concern:

Be it known that I, FREDERICK GU'rzKow, of the cityy and county of San Francisco, State of California, have invented an Improvement in Water-Meters; and I hereby declare the following to be a full, clear, and exact description of the sanne.v

My invention relates to water-meters of that class known as ,piston-metersg and my object is to construct acheap and accurate meter, the employment of hydraulic pressure exclusively for the actuation of the parts, and reversing the stroke by means of a Inechanism which will be hereinafter more fully explained.

Referring to the accompanying drawing for a more complete explanation of my invention, the gure shows a vertical section taken through the apparatus, showing its interior, with the piston and valves at one end of the stroke.

The meter consists of a main cylinder, A B,

having a piston, C, fitted to move within it. This piston is made hollow for lightness, with both ends closed and with the central portion of smaller diameter than the ends, so that an annular chamber, II, is formed around the outside and between the ends, as shown. D E is the valve-chamber, having two independent piston-valves, F F and G G', fitted within it. The two end chambers, D and E, of the cylinder are of larger diameter than the central portion, and the valves consist of two cylindrical heads each, the outer ones, F and G, being of larger diameter than the inner ones, F and Gr', the two parts of each valve being connected together by a shank or shaft, as shown.

Water is admitted into the central portion of the valve-chamber through the pipe or passage l, and it is discharged alternately through the pipes or passages 2 and 8. 4 and 5 are the pipes or passages connecting the opposite ends of the cylinder A B with the valve-chamber, these pipes opening into said chamber upon each side of the inlet-pipe l and between it and the discharge-pipes 2 and 3.

6 is a passage leading from the center of the valve-chamber D E into the center of the cylinder A B, and 7 and 8 are passages leading, respectively, from the opposite ends of the valve-chambers D or E into the cylinder A B, opening therein at such points that when the piston C is at one end of the stroke the passage G will open into one end of the annular chamber H and the passage 7 into the opposite end. The passage S will open into the portion B of the cylinder. In the center of the smaller part of the valve-chamber is an annular stop against which the ends F and G of the valves are checked in their movements toward the center.

The operation will then be as follows: The valve F F being at the right end of the cylinder D E and the valve G G having moved as far to the right as the annular stop in the valve-chamber will admit, water under'pressure entering through pipe l will pass :between th'e smaller ends, F and G', of the two valves and will enterV the pipe 4, which is open, by reason of the valve F F being at the extreme right end of its stroke, passing through the pipe 4, as shown by the arrow, and into the end B of the cylinder, driving the piston C before it until it reaches the end of its stroke, in which position it is now shown. The water under pressure which enters through the pipe l also passes through the passage 6 into the chamber H of the piston C. When the piston reaches a point near the right end of its stroke, the passage 7 will be exposed so as to open into the chamber II, and the water under pressure then passes through the passage 6, the chamber I-I, and the passage 7 to the outer end of the chamber D, where it presses upon the larger piston, F, and thus overcomes the pressure upon the smaller piston, F. These pistons, connected by a shank, as above described, are then moved toward the left and connect pipes 4 and 2. lVater is now allowed to escape through pipes 4 and 2 from the end I3 of the water-cylinder. The pressure upon the piston G will also be relieved by means of the passage 8, so as to allow it to move toward the left. The pistons F F and G G then move in unison toward the left end of the cylinder D E. As soon as the passage 5 is slightly opened to the pressure of water entering through l, by reason of the valve G passing beyond it, the valve F F comes to rest. The stems f and g are in contact after 4 and 2, and until 5 and l are connected. Water will commence to iiow through this pas- IOO sage or pipe and into the end A of the watercylinder, thus starting the piston C on its journey toward the left end of the cylinder. This valve F F', having come to rest in such a position that the passages 2 and 4 communicate with each other through the annular space about the shank of this valve and between the pistons F F', allows the water in the left end, B, of the cylinder to escape through the pipes 4 and 2. The piston G G continues its motion toward the left,co1npleting the opening of the port of 5, the pressure on G from l overcoming the friction. Vhen the chamber Il has reached such a point as to uncover the passage 8, it allows it to receive water through the passage 6 and the annular chamber Il in the same manner that water was previously delivered through 6 and 7. When this takes place, the valve G will be again forced to the right, the inlet-passage of the right end, A, of the cylinder will be closed, and the inlet passage to the left end will again be opened and the operation repeated. By this construction it will be seen that the Whole operation of reversing the movements of the valves and of the piston within the meter is effected by the pressure of the water, and the independent movements of the valves prevent any stoppages or dead-points. The piston C is cushioned at each end of the stroke, either by imprisoning a small quantity of water between the piston and the end of the cylinder as the piston covers the ingresspoint, or by means of a projection which enters a corresponding recess in the end of the cylinder, or by other similar or suitable means.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The main cylinder with the piston having. the chamber H, the valve-chamber with the two independent reciprocating Valves having each two unequally-sized flanges or heads, and supply and discharge passages connecting with the cylinders, as shown, in combination with the pipes or passages 6, 7, and 8, substantially as and for the purpose herein described.

2. In a meter, the main cylinder with a reciprocating piston having a chamber at its central portion, and a valve-chamber the ends of which are of larger diameter than the intermediate connecting portion, in combination with independent valves, each having heads or fianges of different diameters fitting the ends and intermediate portion of the valvechamber, the supply and exhaust pipes opening into the valve-chamber, the pipes connecting the Valve-chamber with the ends of the main cylinder, and the supplemental passages 6, 7, and 8, substantially as herein described.

In witness whereof I have hereunto set my hand.
