DISK WATER-METER.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed December 22, 1906. Serial No. 349,015.

citizen of the United States, residing at Newark, in the county of Essex and State of New I and there are less crevices for Jersey, have invented certain new and useful Improvements in-Disk Water-Meters; and I do ereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to a water meter, and is particularly ada' ted tonieasure a fine stream passing throug a pipe, is'extremely sensitive, being built so that the disk in the meter will not stick, and is also designed to providea meter that has a small number of partsand consequently there are less joints requiring finishing to make them water tight, and it is also easier to assemble the meter,

the accumulation ofdirt and grit.

This invention is an improvement on the style of water meter described and illustrated in my Patent No. 818,430 of April 24, 1906', and the improvement lies in a new base portion that has the passages for the water integral in the base portion, and also provides for an easier running connection between the (gieaii'ing of the registering mechanism and the Another new feature of this meter is the construction of a web ap roximately diametrically opposed to the ividing partition of the disk chamber, and antifriction bearings between the disk and the opposed sides of the partition and the web toprevent binding of the disk on the partition or web when the disk is tilted, and the disk is also made of rubber in a way to'pr event its being warped.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a central vertical section of the meter with the registering mechanism in elevation. M Fig. 2 is a section of the base portion on line 2 in Fig. 1. Fig. 3 is a top viewof the base portion with the disk in place, the partition and web of the disk chamber being shown in section, and Fig. 4 is down on the top I passing a plan of the disk partly broken away at one point to show the stiffening or anti-warping eature.

In this improved me'ter I employ a base portion 10 that is preferably cast and with indentations at all suitable points so as to lighten it without weakening. the structure, and this base portion is su ported on the feet 11. A cover 12, with tiie flanges 13, sits of the base portion and forms, with the central portion of the base portion, a disk chamber in which moves, in the manner usual to these disk meters, a disk 15 supported by the ball 14 which is held fbetween the cover 12 and the central po tion of the baseportion 10. At a suitable point in the disk chamber is arranged a partition 16, shown in Figs. 1 and 3, this partition causing the water to go around in the disk chamber to move the disk, the water coming in throu h the inlet passage 17 which is cast directdy into the base portion 10, and is connected with the inlet ort 18. The Water passing in through the inlet port 18 passes around through the passa e 17 to the other side of the meter, and fo lowing the course of the arrows in F'ig. 3, it actuates the disk 15, and around the partition 16, runs out throu the outlet port 19. The inlet port and t e outlet port have suitable screwthreads 20 on their exterior for attaching the meter to a pipe line.

It has been found that in the gyrations of the disk, and when it tilted at right angles to the partition, there is apt to be a binding if there is a very small volume of Water assing through the meter, and consequently aving little force. This has also been present when rolling bearings have been employed on both sides of the artition, and in order to overcome this di cultly, I have installed a web 21 projecting into tie disk chamber approximately opposite the partition 16, this web not projecting into the disk chamber far enough to interfere with the free flow of the fluid. Bearing on one side of the web and on the oppositeside of the partition, are a pair of rollers 22, these rollers being given plenty of room for operation by reason of the slots 23 and 24, for the partition 16 and the web 21 respectively. These rollers are preferably placed on the side from which the flow is apare secured to the driving shaft 36 of a train hard rubber in most cases, and is'easily made lug to which is secured a conical b ock 27 which has a peripheral roove 28. The

and similar structures, the heat travels back -I claim is:

proaching, and thus take up the thrust and 'allow' a free action of the disk under all conditions.

Sitting on to of the cover 12 is a ca 26 which has the iiange 25, by means of .w ch it is secured to the cover 12. The cap when placed in osition is centered in its relation to the,disii,-and when placed in position is fixed with this relation in mind and irrespective of the re istering mechanism to be hereinafter described. This cap is .of'a somewhat dome like shape, and has a central de ending screw or post 29 passing t ough'and projecting from the ball 14"of the disk, is provided, on its end, with a rollerv 30 which, when the disk is operated, rolls around in the groove 28, and the portion 31 which .is referably a rotating sleeve, engages one o the arms 32 which is fastened to the shaft 33, and on the top of this shaft 33 the projecting arms 34 engage another set of arms 35 which of gearing 37. This whole structure isincased in a suitable casing 10 and any suitable connection is used to transmit power to a suitable registering mechanism 38 which can be read through the sight glass 39,- the whole being adapted to be covered, in the usual Way, by a lid 40. It will be seen from Fig. I particularly, that a veryeasy running device is constructed, and that the roller 30 running in the groove 28 makes a very easy running device, and this coupled with the rollers on the partition and the small web, in the disk chamber, will allow the disk to be tilted under the very slightest pressure.

Whenwater meters of the disk t e are placed in positions in proximity to oilers along the feed ipe, it not much water, or no water atall is eing used, and heats'up the water inthe meter, and one heating of this kind-is liable to warp the disk, as it is made of mis -shapen. I insert, when molding this disk 15, radial wires or small rods 41 which tend to hold the disk perfectly flat, do .not. make it too heavy, and will at all times keep the disk stifi. 1 i

I wish to emphasize the fact that the roller 30, running around in the groove 28 of the block 27, assists in'holding down the ball and taking the wear off the upper surface on which the ball 14 rotates. It has beenfound, in water meters of this class, that the wear on the top of the ball is greater than on the bottom, and this wheel 30, running in the groove assists in counteracting the tendency of the ball and the disk to ride upward.
