DISK WATER-METER.
SPECIFICATION forming part of Letters Patent No. 486,992, dated November 29, 1892. Application filed July 20, 1891. Serial No- 400.189. (No model.)
Y To all whom it may concern.-
, citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusettahavein vented a new and useful Improvement in ater-Meters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a in explaining its nature.
The improvement relates to the followingdescribed improvements in disk meters, and especially to the form of the disk chamber and disk, to the arrangement of the water inlet and outlet, and to the manner of controlling the disk and transmitting its action.
In the drawings, Figure 1 is a view in vertical section of aportion of the meter-case and piston. Fig.2 is a view in section of the meter-case, showing the relation of the passages to the disk or measuring chamber, and also showing in plan the disk and its crank. Fig. 3 is a view in vertical section illustrating a slight modification in the form of the measuring-chamber inlet and outlet passages and also of the crank. Fig. 4 is a view in horizontal section through the case upon the line of one water-passage, also showing in plan the disk. Fig. 5 is a view in section through a case having the inlet and outlet passages shown in Fig. 4 and looking toward said passages. Figs. 6 and 7 are detail views of aportion of the crank mechanism shown in Fig. 3. Fig.8 is aviewiu perspective of the disk with the form of crank represented in Fig. 3, the parts not being united. Fig. 9 is a view in section and dotted outline of the disk and crank of the kind represented in Fig. 3 to illustrate the operation of the crank.
Referring to the drawings, A represents the disk or measuring chamber. It is formed in the case a between the parallel plates a a It is partly divided by the vertical diaphragm or partition a and it contains the disk B. This disk (see Fig. 1) has a central sphere or ball b and inclined surfaces 19' b extending to its outer edge 12 It is preferably made of hard rubber and is hollow or provided with the cavity I). At the upper end of the ball there is a cavity or recess 0, from which expart of this specification,
central line drawn from tends through the ball centrally the hole 0. Sections of the ball extend into cup-recesses c c in the upper and lower plates 0, (1 respectively. A crank 0 extends through a stuffing-box or bearing in the plate ainto the recess 0, where it is offset at c, and from the offset it extends diagonally downward through the axial hole 0' in the the end of the hole and considerably acrossa the center of the upper part of the crank through the center of the ball. The effect of this construction of crank and ball is as follows: First. It conimunicates movement from the gyratory disk to the registering mechanism. Second. It holds the disk in its proper contacts during its gyration and relieves its bearings from undue or undesirable extent of friction. In other words, it keeps it up to its work. Third. It prevents end-thrust of the disk,or,in other words, the extension of the crank-shaft axially through or almost through the disk when the axis hasagyratory path, suspends or holds the disk practically balanced in said path, the tendencyto the development of an end-thrust in either direction being neutralized by extending the shaft past the center throughor very nearly through the ball or disk.
The case, as represented in Figs. 1 and 2, it will be seen, is of the same height throughout-that is, it has parallel upper and lower surfaces or plates, it is circular in section, and the vertical edges are curved.
The water inlet D and outlet D are arranged in relation to the diaphragm a disk chamber, and case so as to provide a continuous circulation or unobstructed rotary movementof the water from the inlet through the meter to the outlet. This is accomplished byarranging the inlet andoutlet so that they are transposed in relation to each other from the positions which they usually occupy in this class of meter. This of course necessitates that the inlet and outlet passages cross each other, and it produces an inlet so disposed to the path of water in the disk chamber that the flow of water from the inlet through the chamber is upon a continuous uninterrupted or unobstructed circular path,
and the relation ofthe outlet to the path of ball to or very near 1 the water is the same, the Water being free to leave the disk chamber in a circular or rotary path and Without obstruction.
It will be understood, of course, that with the old arrangement of inlet and outlet the water is directed by the inlet against the diaphragm a and is obstructed by it and that- V and the easiest path selected for the passage of the Water from the water-main through the 7 disk chamber to the main again. Toobtain this result, it is necessarythat the case should be cast or formed eitheras represented in Figs. 1 and 2 oras in Figs. 8 and 4, Figs. 1 and 2 showing the inlet D as crossing over and underthe outlet D in passages d d, while in Fig. 3 the inlet-passage is represented as above and the outlet-passage as below the diaphragm 01 I prefer the construction represented in Figs. 1 and 2 as producing a better applicationof water-currents t0 the disk. In Figs. 3 and 4 a somewhat different form of disk and of the disk chamber is represented, and also a modified form of the crank C. The crank in this construction, instead of being in one piece, comprises the vertical shaft 6, which passes through a stuffing-box or bearing in the upper plate and diagonally through an inclined cyameter.
lindrical bearing 6 of comparatively-large di- This bearing-piece is secured to the shaft to rotate'with it, but is inclined to the axis of the shaft, and it is contained in a hole 6 extending across the ball of the disk. The shaft e preferably extends into a step orbearing in the lower plate; but the effect of the eccentric or inclined bearing and straight shaft in regard to.the transmitting of the motion of the disk and in regard to holding it to its work is the same as that of the shaft and crank 0.
Having thus fully described my invention,
I claim and desire to secure by Letters Pat- .ent .of the United States- 1. In a water-meter, the combination of the disk or measuring chamber, the diaphragm or division-plate a a gyrating disk, a water-inlet curved toward the diaphragm or partition a and a curved water-outlet upon the opposite side of the partition-plate, as and for the purposes described.
2. A water-meter case having a measuring or disk chamber,awater-inlet in two sections or parts, and a water-outlet crossing the two sections or parts of the Water-inlet, as and for the purposes described.
