lMPRovl-:MENTIN LlQulD-METERS.

Specification formingpart of Letters Patent N0. 173,685, dated February 15, 1576; application filed i February 8, 1876. l

To all whom itmay concern Be it known, that I, D. BRAINARD SPooNER, of Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Water-Meters; and I do hereby declare that the following isa full and exact description of the same, reference` being had to the accompanying drawings and to the letters of reference marked thereon.

This invention relates generally to the class of diaphragmfmeters, but more particularly to the meter shown in my Letters Patent, No. 132,496 and No. 132,497, granted October The novelty in this application consists mainly, lrst, in the peculiar construction of the castings forming the shell or case of the meter, the same beingprovided, in addition to the usual water-ways, communicating with the chambers upon the sides of the diaphragm, with an additional waterway, through which the Vmeasured water is discharged; second, broadly,in the em ployment,in connection with valves of any suitable c onstruction, and primary mechanism for shifting them, of independent auxiliary mechanism for starting them when the primary mechanism fails to act-5 and, third, in the peculiar construction of certain parts of the valve mechanism, all of which will be fully described hereinafter.

In the drawings, Figure 1 represents a central sectional elevation of my improved meter; Fig. l, an enlarged view of the fulcrum of the apex-weight; Fig. 1, an enlarged view of the pin or shaft d; Fig. 2, an end elevation of the mechanism for starting the valves. Fig. 2b, a side elevation ofthe recessed bar which operates directly or indirectly the -registering or dia-l mechanism Fig. 3, a plan view ofthe top plates of the shell casting; Fig. 4, a sectional elevation of the valve-rod and valves.

To enable others skilled in the art to make my improved meter, a nd properly use the same, I will proceed fullyto describe its construction and manner of operation.

For convenience of description, the several mechanisms will be described under different heads, as follows: first, the castings forming the shell or case; second, the valves andthe primary mechanism-for actuating them and, third, the independent auxiliary mechanism for starting the valves when the primary mechanism fails to act.

, First, the castings forming the shell or case These are constructed substantially like those discribed in my Patent No. 132,496, with the exception of the features now pointed out.

A represents the shell or case, consisting-of the castings/ct c, of identical form, which are bolted together at their edges, to form the body of the meter'.` a1 al represent the top plates, each of which is provided with a main waterway, c2, leading to the chamber upon the side of the diaphragm, and an auxiliary water-way, c3, leading to the discharge-opening a4, as shown.

in each half of the shell lie in parallel planes, which are inclined as they extend in an upward direction, toward the vertical center line ofthe meter. a? a5, represent recesses cast in lthe outer ends of the top plates, which are adapted to receive the outer edge or periphery of the flexible partition a6, as shown. a7 a7 represent clamping-rings, provided with screwholes or other means of fastening to the casting, which are adapted to rest in the recesses of the top plate, and securely hold the iiexible partition in place.

'Some of the advantages of the construction described are as follows: By locating the discharge water-way in the lower casting, the independent top plate Aemployed in the meter covered by the patent above referred to is dispensed with, and the construction consequently much simplified. By' locating the water-ways in parallel lines, inclined toward the center, as described, the space is economized and the parts compactly arranged.

. By means oftherecesses and clamping-rings a ready and secure means of attaching the parttion to the casting" is provided, and each also is held entirely independent of the other, and of the remaining parts of the machine.

Second, the valves and the primary mechanism for actuating them: The construction of the valve mechanism and its manner of operation are Substantiallyrlike that described in my Patent No. 132,497, with the exception of such points of diiference as will be pointed out.

B represents the valve-box, constructed in These main and auxiliary water-ways formed two parts, b bl, and provided withvthe ports b2 b2 b3 b3, and the water-ways b"l b4 b5, communi-v catingwith the water-ways in the lower cast' for the bar J, uniting the disk-levers, as shown.

C C representI arms projecting from the top of the casting, each of which is provided with journal-ears, c c, as shown. D D represent links provided at each end with a closed eye, d d, by means of which, and a transverse shaft or pin, d1, they are secured'above to the ears c c of the arm G, and below to the ears of the swinging carrierframe, as shown. Each is provided also with an opening, d2, located at right angles to the eyes d, which is adapted to permit the` center-pin of the valve-shaft to have properplay, without interference. The pins d1 are also provided with shoulders d3, by means of which the links are centrally held and accurately guided in all their movements. E represents the. carrierframe supported bythe links, as before described, and provided also with -the transverse block f, having a dovetailed recess adapted to hold the base of the prismatic block j", as shown. F represents the valve-shaft, consisting of a metal rod of suitable length, which is held at its ends /by c nter-pins, as described in my Patent No.- ll. g g g represent disks formingv apart of lt shaft, which are located at the proper points, as shown. H represents the valves proper, consisting of rings of hard rubber, of suitable form, which may be attached to the disks of the shaft, or to the shaft itself, by screw-threads, or by molding them onto the lnetal, or in any other proper manner. I represents a lever, provided at one end with a socket or` eye, having a friction-sleeve or bushing,'z', of hard rubber, and at the other end with a weight, having below'v a dovetailed recess adapted to hold the prismaticblock il, as shown. This friction-sleeve, it will be observed, extends beyond the sides of the eye, and bears at its end against the inner sides of the lever-arm. This lever is pivoted between the arms of the disk-lever by means of a pin or shaft, 2, as shown. J represents a bar, by means of which the disk-levers are united and caused to move together.

The general operation of this valve mechanism is similar to that described in my patent above referred to, and it need not, therefore, be particularly described here.

Some of the advantages of this improved construction are as follows: l

By locating the bar connecting the disklevers below the valve-box, the parts are more compactly arranged, and space is economized.

By the employment of hard-rubber valves in connection with a metal valve-rod, the advantages of both materials are obtained, the rubber being especially adapted for the valves and the metal for the rod.

By the employment of a friction-sleeve of other, and consequently the friction is reduced'.

By the employment of hard rubber in connection with the metal surfaces, also the corrosipn which would arise from the impurities and dchemical substances in the-water, it' metal surfaces were brought in contact, is entirely avoided.

Third, the independent auxiliary mechanism for starting the valves when the primary mechanism fails to act: K represents a lever supported in any proper bearing attached to the stationary portion of themachine, one end of which is secured in any suitable manner to a k lc of the disk-lever, as shown. The other end extends in a downward direction, and is adapted to move between the limiting-shoulders of the extension 113 of the center-pin of the valvethedisk-arms, which is provided with a central recess, adapted, when the valve is in operanism for actuating the registering or dial mechanism. y

The operation of this mechanism is as follows The valves are ordinarily actuated by the mer patent, the movement ofy the lever-arms Y being communicated to the apex-weight which actuates the swinging frame carrying the valves. If from any cause, however, this fail to move from any cause, the continued movement of the leverarms will actuate the starting-lever, and consequently move the valve-rod and valves. As soon asthe valve is started, the primary mechanism acts `to complete the movement. I

vCertain modifications may be made in the construction shown, without departing from the spirit of my invention.

1f desired, the valve mechanism, or .the starting mechanism, or both,may be employed in connection with other measuring mechanism, such as a sliding or rotary piston.

The valve-shaft, if desired, may be provided with an enlarged bearing-surface at its ends, adapted to rest against a corresponding surand the two be rigidly connected together for resist shock and wear.

The starting mechanism, constructed 'substantially as described, or its equivalent, may be employed in connection with any valve which leaves its seat, and with any primary mechanism for shifting the valves.

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

1. The castings a a having the main waterways a? a2, and the discharge water-way c3,

substantially as described.

hard rubber inthe eyeof the lever of the apex-V weight, metal surfaces are separated from each bar, k, attached to the upper ends of the armsshaft, as shown. L represents a bar uniting ation, to give movement to any proper mechprimary mechanism, as described in my forweight should hang in its movement after having passed the apex, or the valves should face upon the inner face of the carrying-frame, i

the purpose of strongly uniting the parts to.
