SPECIFICATION forming part of Letters Patent No. 488,504, dated December 20, 1892. Application filed June 16, 1892. Serial No. 436.978. (No model.)
To all whom t may concern:
Be it known that I, JAMES B. KNICKER- BOOKER, of Indianapolis, county of Marion, and State of Indiana, have invented certain new and usefullmprovements in Gas-Meters; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like ligures refer to like parts.
My invention relates to the construction of gas or fluid meters, and more particularly to the spring mechanism for throwing the valves, and is an improvement on the device described and claimed in Letters Patent N o. 468,008, issued to me February 2, 1892.
In the drawings Figure 1 is a longitudinal section of my device. Fig. 2 is a central cross section of the same on the line frx, Fig. 1. Fig. 3 is an enlarged top View of the spring mechanism partly broken away.
In detail, (1) is a divided casing having an inlet (2), outlet (3), and a channel or passage Way (f1) for the gas, leading from the inlet to the gas chamber and from thence to the outlet.
(5) is a diaphragm secured between the halves of the casing, dividing the interior into two chambers (6 and 7). The diaphragm is composed of a central flexible sheet with metal backing plates (8) on either side, and (9) is a collar notched on opposite sides at (10) to receive the bifurcated arms of the lever (11) which operates the register (12). The collar (9) tits snugly over the sleeve (13), which is formed integral with the plate (14), and passes through the diaphragm, the plate iitting up against the same on one side and the collar (9) on the opposite side, the collar being retained on the sleeve by the nut (15) secured on the end of the same.
(16) is a valve rod which passes loosely through the central openingof the sleeve (13), the latter being cored out, as shown in Fig. 2, one end only bearing on the valve rod, the nut (15) performing asimilar office at the opposite end oi' the sleeve, thus reducing the friction to a minimum.
(17) is a double valve mounted on the valve rod (16) on the inlet side of the casing, and operating alternately to close the ports (18 and 19) therein, and (20) is a single valve on vvided with brass seats,
the opposite end of the rod, operating in a similar manner on the ports (21 and 22) on the outlet side. The valve ports are all proas shown in Figs. 1 and 2, for reducing the wear by friction.
At either end of the plate (14) are formed brackets (23), and to each of these is pivoted the arm (25) having the slot (26). (27) is a a double bracket rigidly secured to the valve rod at a point a little to one side of the double valve (17), and to opposite sides of this are pivoted arms (2S), the outer ends of which straddle the arms (25), pins (29) passing through their ends and work in the slots (2G), the pins extending 'outward on either side, and coiled springs (30) connect these arms together.
(31) is a curved base platesuitablyseeured to the inside ofthe casing around the double valve (17), and are arms extendingtherefrom, their outer ends having slots (33) curved on a radial line with the pivotalpcints of the arms (28), and screws 0r pins pass through these near their center and work in the slots (33), and the movement of the arms is thus limited.
The operation of my improved meter is similar to that 0f the one shownin myfcrmer `patent, the gas entering through the inlet (2), passing through the ports (4) in the direction of the arrows around the passage way to the gas chamber (7) on the left hand side of the diaphragm, as shown in Fig. 2, the expansion of the gas forcing the diaphragm to the right and carrying with it the plate (14) and the slotted arms (25), the ends of the slots engaging with the pins (29), carrying the spring arms (2S) with it in their movement until the gas chamber (7) is iilled, at which time the pins(29) carrying thesprings (30) will have passed a straight line with the pivot pins of the arms (2S) in the double bracket (27), and the tension of the springs will operate to throwthe valve rod to the left, closing the port (18), and cutting off the flow of gas into the chamber (7), opening the inlet port (19) into the chamber (6), and at the same time opening the outlet port (21) from the chamber (7), and closing the outlet port (22) from the chamber (G),and the gas in the chamber will then pass out through the pas- IOO sage way (4) and through the outlet (3). The same operation is now repeated. The gas en tering into the chamber (6), slowly filling the same, the diaphragm is carried toward the left, and with it the slotted arms (25), until the ends of the slots engage with the pins (29), with their springs carrying the arms (28) backward until the pins pass the line of the pivot points of the arms (28) in the double bracket (27), when the valve rod with its valves will be thrown to the right, bringing thegsprings and connecting parts back to their first position.
What I have obtained by this construction of the spring mechanism for throwing the valves is one where thereis the least possible friction, the parts of the throwing mechanism being equally divided on either side of the valve rod, and therefore the friction is equal, and the meter can be placed in any desired position and work with equally as good results. As will be seen, the only points bearing against the valve stem are at each end of the sleeve (13), which passes -through the diaphragm and around the valve stem, and no matter in what position the meter is placed, it will at all times give the same results, whereas in my former device there was always a good deal of friction on the valve stem and moving parts, and when placedin some positions the friction was so great that the meter would not operate as well as it should. Another improvement over my former meter is that the present device is much simpler in construction, more easily put in place, and the various parts are more readily adjusted, and,when in operation, the valves are always held firmly to their seats and the lnovements of the various parts are always in the opposite direction from the movement of the valves when thrown, so that a valve can never be moved prematurely, and as in my former device the throw is instantaneous In brief, what I have accomplished in this device is to retain the meritorious features of my former device, and to improve and perfect those that were likely to impair its successful operation.
The registering mechanism (l2) of the present device will be readily understood, as it is similar in construction and operation to that shown in my former patent.
In some cases it may be desirable to form the curved slots 33, in the pivoted arms, 2S, instead of in the brackets, 32, as shown in the drawings, and in any case where this is done the screws or pins which form the stops on the arms, 28, would be formedon the ends of the brackets, 32. This modification, however, would not be a departure from the principle of my invention, for the operation of the several parts would remain the same, the positions only being reversed.
What I claim as my invention and desire to secu re by Letters Patent is the following:-

In witness whereof I have hereunto set my hand this 23d day of April, 1892.
