IMPROVEMENT IN LIQUID-METERS.

Specification formingpart of Letters Patent No. 108,804, dated November 1, 1870.

'Toall whom it may concern .eflicient means for measuring water, so that the quantity discharged from a service or other pipe may be accurately ascertained and registered; and it consists in operating, in a cylindrical chamber,-by the pressure of the water,

a radial arm or wing, and in openingand closiug induction and discharge valve ports by means of a falling weight, which is raised by the arm or wing, and in the mode of actuating the register, as will be hereinafter more fully described.

In the accompanying drawing, Figure 1, Plate 1, represents a front view with the valveport cover off. Fig. 2, Plate 1, is a vertical section of Fig. l on the line am. Fig. 3, Plate 2, is a view of the meter from the back side with the side plate ofi', showing the movable weight and the manner in which it operates upon the valves. Fig. 4, Plate 2, is a View of the front with the front plate off, showing the radial wing, the vertical fixed radial plate, and the front valve-port.

Similar letters of reference indicate correspondin g part-s.

A is the casin g, which is a longitudinal section of a hollow cylinder, with a coveringplate at each end. B is the front plate, and G is the back plate. The case A rests in a horizontal position on the bed-piece I). E is a vertical fixed partition, which fills the interior of the cylinder. F is the arbor of the radial and oscillating wing. One end of this arbor is supported by the partition E, the other end by the front covering-plate, B. G is the radial and oscillating wing attached to the arbor F.

By the partition E the casing A is divided into two compartments or chambers, O and H.

The principal compartment 0 is the waterchamber, in which the wing G is made to 0perate. The other compartment, H, is the wateniuduction chamber, where the weight I op crates. h

J is a vertical fixed partition-plate, which extends from the central arbor, F, to the casing, and forms an abutment, which, with the oscillating arm G, divides the water-chamber into two compartments, which are filled and discharged alternately as the valves are opened and closed. K and L represent the valves. A front view of K is seen in Fig. 4. Both are attached to a spindle, which passes through or is supported by the vertical plate J Onehalf of the port-openings of each valve is on each side of the plate J, and each valve is so arranged that these ports are opened and closed-alternately. K is the valve in the induction-chamber H, and L is the valve over the eductionports in the covering-plate B. M is the eductiou-chamber, and to N the discharge-pipe is attached.

The water enters the chamber H through the pipe M underpressure, and passes through the valve K and the ports in the partition E, on one side of the partition-plate J, and forces the wing G upward and around the center of the casing, carrying with it a crank, P, which is fast to the arbor F, which, in its rotating motion, comes in contact with and lifts the weight I and carries it up past the center, where the weight, which turns loosely on the arbor F, isthus carried past the center of its gravity, it drops, and its descending force changes the position of the valves, opening a porton one side of the plate J and. closing a port on the other side for each valve every time the weight thus falls.

B and S are bars, attached by pivots to the valve in the chamber H. These bars are supported and guided in recesses in the stationary bar T, which is fast to the partition E. U is a curved plate attached to the casing A, which acts as. a stop to limit the descent of the weight, as seen in Fig. 3. As the weight drops it strikes the ends of one or the other of the bars E S, and forces it down suificiently to change the valve before it strikes the stop U.

By thus opening and closing avalve-port in each compartment of the water-chamber every time the weight is caused to fall, the water is received and discharged into and from those compartments alternately, and the operation is continued as long as the pressure and flow of the Water is suflicient to operate the win g G. V represents spring-packing on the outer end of the wing G.

It will be seen that by the action of the weight the valves are changed simultaneously. At the front or e'duction side the port of the i'ull chamber is opened and the other ort is closed, and at the otheror induction s de the operation is reversed.

Each discharge is registered bymeans of the ordinary multiplying mechanism usually employed for the purpose, which is actuated by the ratchet and pawl seen in Fig. 1.

WV is the ratchet-wheel, and X is a springpawl, confined by clips on the front of the meter. Y is a cam on the projecting end of the central arbor, F. At every discharge of water or strike of the wing G the cam raises the pawl, which moves the ratchet. one tooth. The pawl is hvld up to its work by the spring Z, and its back movement is produced by the recoil of the spring Z.

The discharge-pipe is attached at N, pro- 'vided with a stop-cock, so that the water acts stantially as and for the purposes described.

2. The water-chamber 0, divided into two compartments by means of a fixed partitionplate, J, and an oscillating wing, G, by which the water is received and discharged alternately therefrom, substantially as described.

3. The cam Y, pawl X, and ratchet U, by means of which-motion is imparted to the registering mechanism, all arranged substantially as described.
