SPEQIFICATION forming. partof Letters Patent No. 530,743, dated December 1 1, 1894.

Application filed `Tuly 28, 1894.

To alt whom t may concern.- v

Beit known that I, GEORGE B. BAssErr, of

Bualo` New York, have invented a new andl useful Improvement in Water-Meters, which improvement is fully set forth in the following speciication. y

This invention relates to improvements in water meters, and more particularly to disk water meters of that class as shown in Letters Patent No. 501, 203, granted to me on the 11th day of July, 1893.

The objects of my present invention are principally to improve the construction and arrangement of the casing, disk chamber, and other points in the construction of theseme-l ters for ther purposes of reducing the cost of manufacture, allowing the more ready assemblage and separation of parts, the drainingof the meter when not in use, increasing the durability and efficiency and giving other advantageous results.

I will now proceed to definitelydescribe the manner in which I have carried out my iuvention and then claim what I believe tobe novel. y

In the drawings-Figure 1; is a central vertical section of. my improved meter. Fig. 2; is an elevation of the sanne` with the outer casing in section to show interior parts. Fig. 3; is a top plan view of the lower casing with disk chamber resting upon it. Fig. 4; is a top plan view of the lower casing. Fig. 5; is a detail sectional View of the'disk spindle bearing. Fig. 6 5 is a detaill view ofthe diaphragm and bearing piece for edge of disk. Fig. 7 5 is-a top plan View of disk showing location of diav phragm and bearing piece for edge of disk.

Referring to the drawings the working parts except the register are surrounded and contained in a separate outer case consisting of two parts 1 and 2 bolted together at their danged meeting edges as at 3, (Figs. 3 and 4.)

4 is the stuffing box shaft protruding through stuffing -box 5 where it may be attached to a register of any well known form mounted on outer casing 1. On the inner end of shaft 4 is permanently mounted the toothed gear wheel 6. The outer casing 2 contains both the inlet and Outlet spuds 36 and 37, and also the radial partition 28 at right angles to the line of the spuds and which divides the space within casing 2 into two compartments Serial No. 518,788- (No model.)

26 and 27, the inlet spud communicating with one compartment and the outlet spud with the other compartment.

The disk chamber consists of two parts 18 and 19 fastened together by screws and resting lon the outer casing 2 and web 28, and held in place by the annular notch 30 cutin casing 1 which receives the annular projection of plate 19 of the disk chamber. The space surrounding the disk chamber and between it and the outer case is thus divided into three ompartments 25, 26 and 27.

In the spherical side wall of part 18 ofthe disk chamber are located'the inlet and outlet ports 32 and 35. Port 32 communicates with the compartment 25 and port 35 is covered by the hood 34 and communicates, through the elongated passage 33 in plate 19, with compartment 26. At the apex of the conical end Wall of part 18 is a spherical annular bearing for the disk ball 15 and an inclosed recessed chamber 13 in which is located the beveled bearing roller 22 mounted on the cylindrical sleeve 12 and held in place by the ring 23 sprung into a groove cut in sleeve 12, (Fig. 5). v By this construction the disk spindle is retained in its circular path Without undue wear or friction, and the disk and controlling spindle are entirely inclosed in the disk chamber and recess aud thus maintained in static equilibrium. No adjustment is required to relatively center the disk spindle and its bearing roller. Between sleeve 12 and shaft 11 is removably secured a bushing 24 (preferably of hard rubber) which may be readily removed and substituted when worn.

In the center of plate 19 which forms one end of the disk chamber is a spherical socket or bearingfor pivot ball 15 of the disk. The plate 19 has radially formed across its outer surface the. web 29 which registers and rests upon the ,radial partition `28 ofvouter casing'2 thus sealing the inlet and outlet compartments 27 and 26 from each other. The holes 31 are formed in the annular projection of plate 19 to afford communication from the inlet compartment 27 and spud 36 to the compartment 25 and inlet port 32 and at the same time to strain out any large foreign substances that otherwise might clog the working parts of the meter and also to break up the inflowing current of water so that it will pass into IOO the disk chamber through port 32 with a nearly uniform velocity at all points.

2O is a diaphragm or plate located between the inlet and outlet ports 32 and`35 and secured Within the disk chamber by resting in a groove cut in the spherical side Wall and end cone of part 18 and secured in place by the projection 21 which passes through the wall of the disk chamber and is riveted down.

To reduce the friction caused by the metallic web 16 of the disk against diaphragm 20 a strip 3S (preferably of hard rubber) is secured to the side surface of the diaphragm to receive the thrust of the disk.

Vithin the disk chamber is located the oscillating or nutating measuring disk composed of the metallic web 16 on each side of which are securely fastened the parts of the pivot ball 15 (preferably of hard rubber) by the disk spindle 14 which is threaded into one section of the ball and has the annular collar 17 bearing against the other section.

The web 16 is slotted to receive the diaphragm 2O with bearing piece 3S.

The intermediate gearing that communicates and reduces the motion from the spindle 14 of the nutating disk to the stuffing box shaft 4 is mounted on the disk casing. The shaft 11 is bent at its lower end to engage the disk spindle 14 and it is held in place by being permanently driven into pinion l0. Pinion 7 and gear Wheel 9 rotate about pin 8 which is permanently fastened into the disk casing. Y i

A small hole 39 is formed in the spherical Wall of the disk chamber at a point nearly ninety degrees from the diaphragm 20 and on the side of the inlet port 36 to facilitate the complete drainage of the disk chamber where the meter is set in a vertical pipe with inlet spud 36 pointing downward.

In operation the Water enters through spud 36 to the compartment 27,then passes through the holes 3l into compartment 25 and thence into themeasuring disk chamber through the inlet port 32. After passing through the disk chamber in a circular path and oscillating the measuring disk it passes out port 35 through elongated opening 33 to compartment 26 and outlet spud 37. When the measuring disk continuously oscillates the spindle 14 travels in a continuous circular path and engages the bent end of shaft l1 rotating pinion lO which engages with gear wheel 9 rotating pinion 7 which engages with gear Wheel 6 rotating stuing box shaft 4 and operating the register.

It will be seen by the arrangements and disposition of the parts that when the meter is placed on a horizontal pipe all Water Will drain from it through inlet spud 36 except that contained in compartment 26, and when meter is placed on a vertical pipe all Water will drain from it through inlet spud 36. It will also be seen that as both the inlet and outlet spuds are Wholly in part 2, part 1 on which is the register may be fastened to it in any position and the register brought into a suitable position for reading irrespective of the position of the inlet and outlet spuds.
