IMPROVEMENT IN WATER-METERS.

Specification forming part of Lettrrs Patent No. l7 6,07S, dated April 11, 1876 ;applica.tion filed January 24, 1876. i

To all whom it may concern:

Be it known that I, AUGUSTUS SEQUEIRA, of the city and county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Water-Meters; and to enable others skilled in the art to make and use the same, I will proceed to describe, referring to the drawings in which the same letters indicate like parts in each of the ti gu re s This invention relates to certain improvements in water-meters; and consists more particularly in the peculiar construction of the piston having no actuating rod or other fixture attached thereto, and its combination with compound valves in the other chambers of the meter, whereby a regular and automatic action of the device is insured without the intervention of any mechanical motor, all as will now be more specifically and in detail set out and explained.

In the accompanying drawings, on Sheet 1, Figure 1 is a top view of the meter. Fig. 2 is a side view, showing a section through the line E F, on Sheet 2. Fig. 3 is a vertical section through the line 0 D, on Sheet 2. Fig. 4 is a vertical end section through the line A B, on Sheet 3, showing the end of the piston in its cylinder. and the ends of two valves in their chambers. On Sheet 3, Fig. 5 is a side view, showing one of the valves, its chamber, and ports leading to and from the same. Fig. 6 is a horizontal section through the line G H on Sheet 2.

a is the cylinder, in which the piston 1) vi brates. a and a are valve chambers, in which the valves a and a are fitted to play closely and freely therein. The piston 12 and valve a are provided with hubs or detents so on each end, which strike their respective heads each alternate motion, and by which the desired and exact amount of play is regulated, and determine or fix the accurate measurement of fluid. The valve or is provided with lugs h, which extend through and play in slits formed in or through the cylinder, directly under the seat of the valve to, against which the end of piston b strikes, and move it so as to open alternately the ports.

The operation is as follows: The Water is first introduced into the meter through the induction-orifice c, and upward through properl v-formed passages to the top of valve-chamber a; thence right and left through ports at d into compartment 0; thence down through passages to port f, and into cylinder a, be tween the head of the cylinder and the end of the piston 11, and by its pressure moves the piston to the opposite end of the cylinder, and

in its movement it strikes the lug h in the valve a, and moves it in the same direction with the piston, and opens the port 70, which leads into portj, and allows the water to pass directly into the valve-chamber between the head and end of the valve a and moves it forward to the opposite end of its chamber, and forces the water from the chaznber through passages to the discharge n, and in doing so the water enters the compartment 0; thence through the ports f between the cylinder and piston-heads, and, by the pressure of the water, the piston is reacted to the opposite end and drives the water through port f and compartment c, and through the discharge-passage out at port a, and vice versa, a continuous action and steady discharge will be produced.

The dial for registering the measurement of fluid forms no part of this invention.

Having thus described the construction and operation, what I claim, and desire to secure by Letters Patent. is-- 1. In a water-meter, the sliding balancevalve a with its heads I II III IIII, and detents x, operating in and combined with chamber 60 substantially as and for the purposes set forth.

2. The piston I), having detents m, and operating in chamber a, in combination with "alve a, having lug IL, substantially as and for the purposes set forth.

3. Th'e combination of cylinder a, having piston I), provided with detents a, and valve chamber a having the valve a, lug h, with chamber a having valve a substantially as and for the purpose set forth.
