SPECIFICATION forming part of Letters Patent No. 767,328, dated August 9, 1904.

Application filed November lti, 1903. Serial No. 181,351. (No model.)

To (all whmn it may concern.-

Be it known that I, JOHN H. CoNNELL, a citizen of the United States, residing at Charleston, in the county of Kanawha and State of est Virginia, have made certain new and useful Improvements in Meters, of which the following is a specification.

My invention is an improvement in meters for measuring water and other liquids, and has for an object to provide a novel construction of meter which can be easily assembled and taken apart for repairs or for any other purpose and which will operate efficiently without any appreciable diminution in the pressure of the water; and the invention consists in certain novel constructions and combinationsof parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a bottom plan view, and Fig. 2 is a vertical cross-section on about line 2 2 of Fig. 1, of a meter embodying my invention. Fig. 3 is an elevation of the meter on about line 3 3 of Fig. 2, the top of the casing being removed. Fig. 4: is an elevation of the inner side of the channeled bottom plate of the meter. Fig. 5 is a detail cross-section on about line 5 5 of Fig. 3. Fig. 6 is a detail elevation of the lower side of the valve-chamber with the valve in place. Fig. 7 is a detail elevation of the valve-chamber, a portion of the casing, and the operating parts somewhat similar to but showing the parts in a different position from that shown in Fig. 3. Fig. 8 is a detail perspective view of a portion of the casing. Fig. 9 is a detail cross-section on about line 9 9 of Fig. 7. Fig. 10 is a detail perspective view of the slide-rod. Fig. 11 is a detail perspective view of the rocker, having the inlet and discharge valves. Fig. 12 is a detail perspective view showing the body of the oscillating blade and the indicator-stem and packing-strips detached. Fig. 13 is a detail perspective view, partly broken away, in section of the valve-chamber; and Fig, 14 is a detail perspective View of the shifter.

In carrying out my invention I provide the I 5 on opposite sides of the valve-chamber E, and

the channeled bottom plate F, having the .curved channel F, registering at its ends f,

with the outlet-openings C and D and communicating midway said ends f with the discharge-opening F which is controlled by the check-valve f which operates to prevent back pressure. In operation the water delivered to the'casing is discharged alternately from the openings Cand D and passes through the channel F to the discharge-opening F means being provided to secure the alternate discharge of the water through the openings C and D, as will be described.

The valve-chamber E is provided within the casing and communicates at its outer end with a projecting portion a of the casing, to which the supply-pipe G, having a throttlevalve Gr, discharges, the discharge from the pipe Gr passing to the interior of the valvechamber E, as will be understood from Fig. 3 of the drawings. The valve-chamber eX-' tends nearly to the middle of the casing and is provided in its inner end with a curved re cess e, which fits the shaft portion h of the oscillating blade H, which oscillates in the chamber between the position shown in Fig. 7, in which it abuts one edge e of the chamber E, to an opposite position, in which it abuts the edge e at the inner end of the chamber E, as will be understood from Figs. 3 and 7 Fig. 3 showing the blade in its intermediate position., As the blade moves from the position shown in Fig. 7 to its opposite position it will force water in front of it out through the opening C and then on the return movement it will force the water which has entered in rear of the said wing out through the opening D, the operation continuing from time to time as long as the water is discharged from the pipe G to the valvechamber.

The blade H'is provided in its sides and outer ends with grooves H, preferably V shape in cross-section and having the central longitudinal rib 7?, on which pivots the packingstrip I, the latter having the central groove 2', fitting on the rib 72/ and slots or passages if being provided leading from the opposite edges of the blade, so the pressure of water on one side or the other will properly tilt the packing to cause it to tightly pack the blade when the same moves in one or the other direction, as will be understood from Figs. 7, 9, and 12 of the drawings. The cylindrical sleeve /1 of the blade H journals on a stud B on the plate B and is pro vided at its outer end with a pin 7b, which receives the slot J in the inner end of the tapered head J of the indicator stem J, whose outer end at J may be suitably connected with any desired form of register.

The valve-chamber is provided in its opposite sides with openings Z for the passage of the slid e-rod K, which latter is provided with a stem K within the valve-chamber and in position to operate the valve-shifter presently described. This slide-rod K is guided at K within the casing and is arranged at its ends to be operated by the blade H to the position shown in Fig. 7 when the said blade reaches the end of its stroke in one direction and to be shifted to the opposite position by the engagement of the blade when the said blade reaches the position. opposite that shown in Fig. 7, as will be understood from'Fig. 3 of the drawings. In this connection it will be noticed Fig. 7 shows one position of the sliderod and Fig. 3 the other position of the said rod, as well as of the parts associated therewith, as will be described. a

The valve-chamber is also provided in its opposite sides with the outlet-ports C and D, the water which passes through the port 0 being ultimately discharged from the casing through the outlet 0, while the water passing through the port D is discharged ultimately from the casing through the out-let D, the valve-chamber being provided with curved seats C and D at the inner ends of the ports G and D, said seats U and D conforming to the ends of the feed or inlet valve, as presently described.

In Fig. 11 I show the rocker L, having the valves C and D controlling the outlets C and D, and the intermediate or head portion L, having the valve portions (1* and D", which control the ports 0 and D, as will be understood from Figs. 3, 6, 7, and 11 of the drawings. hen the rocker L is in the position shown in Figs. 6 and 7, the port D will be closed and the port C will be open, so the water passing into the chamber may pass thence into the casing, so it will operate upon the blade H to force the same from the position shown in Fig. 7 toward the opposite position of said blade, as before described. As the blade moves from the position in Fig. 7 to its opposite position it will force the water within the casing out through the outlet C.

For operating the rocker L from the blade I provide said rocker with an arm L, which operates in the fork M of a lever M, which is pivoted at M and has its end M provided with the arms NP for engagement by the swinging end of the valve-shifter N, so the movement of said valve-shifter N from the position shown in Fig. 3 to that shown in Fig. 7 will shift the rocker L in such manner as to uncover the outlet (1, close the outlet D, close the port C, and open the port D, while when the shifter is moved to the position shown in Fig. 3 the outlet C will be closed, the port D opened, the port D closed, and the outlet U opened. The shifter N is pivoted at one end, preferably by means of the eyes N, fitting on the hooks i 2 in the offset a of the casing, and is provided at its swinging end. with a roller N to engage the arms M" of the intermediate lever and also has between its ends a laterallyelongated opening N, in which operates the stem K of the slide-rod K. This shifter is operated by the slide-rod and is actuated by a spring 0, preferably a coil-spring, connected at one end, 0, with the casing and at its other end with the shifter and preferably operating at its said other end in a thimble a in the shifter, a glass ball-bearing 0 being provided for such end of the spring to prevent the shifter from stopping on the center. The purpose of this spring 0 is to quickly throw the shifter to the end of its stroke after it has been operated past the center by the action of the slide-rod, and the slot N in the shifter, within which the stem K operates, is to permit this quick movement of the shifter toward the end of its stroke in the operation of the invention.

From the foregoing the operation will be readily understood. It will be noticed that when the parts are in the position shown in Fig. 3 water will flow from the valve-chamber through the port C, as indicated by the arrows, and the blade will be moved in the direction of the arrows, forcing the water which may be in front of it out through the outlet D. As the blade reaches the end of its stroke it will strike the end of the slide-rod K and will quickly shift said rod toward the position shown in Fig. 7. This will move the valve shifter and the rocker carrying the Valves to the position shown in Fig. 7, closing the outlet D and the port G and opening the outlet 0 and the port D, admitting water through the outlet D to operate upon the blade H and force the same to its opposite position. hen the blade reaches such opposite position, it will readjust the parts through the slide-rod in the manner before described, and the operation will be repeated from time to time. The body of the rockerL is grooved on its under side at L to permit sand to pass out.

It will be noticed that the several parts are so constructed and connected that they may be readily assembled or removed in a few minutes and that the operation of the meter is positive, each stroke forcing out a driven quantity of water.
