entre EUGENE ROBERTS, OF SALT LAKE CITY, UTAH.
DEVICE FOR METERING FLUIDS.
Specification of Letters Patent.
Patented Nov.. 20, 1911 '3'.
Application filed February 7, 1914. Serial No. 817,318.
To all whom it may concern: i
Be it known that I, EUGENE ROBERTS, citizen of the United States, and resident of Salt Lake City, county of Salt Lake, State of Utah, have invented certain new and useful Improvements in Devices for Metering Fluids, of which the following is a specification.
This invention relates to devices for measuring a flow of fluids and is intended to overcome certain objections and difficulties that are incident to the ordinary methods of performing this work when the en-` tire fluid body to be measured is passed directly through a measuring device.
In its essential features the invention comprises a main valved passage for the flow of the fluid combined with a by-pass which is also provided `with a valve cordinated to the valve in the main passage and a registering device to `measure'the liquid passing through the by-pass, a fixed ratio being preserved between the volume of liquid passing throughY the main passage and that passing through the by-pass.
These and other features of the invention will be fully described hereinafter and will be defined in the claims hereto annexed.
In the drawings:
Figure l is a vertical sectional view illustratinglthe preferred mode of embodying the principle of this invention;
Fig. 2 is a plan viewV of the mainvalved passage; .and
Fig. 3 1s a cross-section of the valved bypass.
In the practice of my invention accord-` ing to the form illustrated in the drawings I provide a casing a formed with an inlet 0; to which the water supply pipe is conveniently attached and with an outlet passage a2 for attachment to the outlet pipe.V
`Within the casing is mounted an annular valve chamber b whose inner wall is provided with vertical `groovesb2V which increase in depth and width to the top and disappear at the extreme bottom of the valve chamber. i
The valve C is an ordinary type of piston valve normally seated upon the valve seat b to completely close the passage against the iow of liquid. Obviously if the outlet pipe is opened the pressure of the water in the outlet passage a2 will be diminished so that the valve will be raised from its seat by the greater pressure of the Water beneath it. Obviously the farther the valve piston is lifted from its seat the greater will be the flow of water through the valve chamber owing to the increasing size of the passage toward the top. llhen the outlet is closed the pressure in passage a2 becomes equal to the pressure in the passage a and the valve is returned to its seat by means of the piston rod c2 which isr actuated by a series of removable weights m, or the like to restore the valve to closed position.
In the lower part of the casing is placed an adjustable outlet pipe CZ having a series of tapered ports or openings at el which are normally closed by a tubular valve e when the valve C is in closed position. rlhis slide valve e is connected by the extension arm e with a slotted bell crank lever e2 mounted 1n a bracket e3 whose other slotted arm is connected with the rod 04 extended downward from the piston C. n Obviously when the valve C is lifted from its seat this motion is transmitted through the bell crank lever to the slide valve e so as to uncover the ports fl in the by-pass pipe d. The ports CZ are graduated to correspond to the `tapered passages in the valve chamber Z) so that as the upward movement of the pisto-n C continues to increase the available openingfor the flow of liquid the corresponding uncovering of the ports d produces a corresponding increase in the capacity of the by-pass ports d.
In order to properly regulate or adjust the relative capacities of the respective valved passages affected by the movements of their respective valves, I provide for adjustment of the connections between the two valves which may be of any suitable type. In this case the bracket e3 which forms the fulcral support of the bell crank lever e2 is made adjustable by mounting it to slide in suitable retaining brackets c4 on the inside of the casing, said bracket being engaged by an adjusting screw e5 which projects through aproperly packed aperture in the wall of the casing in order to render it accessible to the attendant. Obviously according to the arrangement shown, as the bracket e3 is lowered the distance between the center of the lever and its point of engagement with the extension e of the slide valve is shortened relative to the length of the power arm of said lever so as to vary the relative lengths ofA traverse of the ltvvo valves. At the same time the by-pass pipe Z is itself adjustably set in the casing by means of a screu7 threaded connection as shown at Z3 so that it may be adjusted to proper relationship with the slide valve e. Bynleans of the pipe CZ* the pipe CZ is connecte'd'vvith any suitable type of Water regis! ter or meter shown at cZvthi-ough which the liquid passes into the return pipe Z6 which delivers it into the outlet passage a2.
f In order that the device may be adapted for use in registering very hot liquids which Would otherwise affect the accuracy of the meter I insert a cooling coil f through which the liquid entering the by-pass may be circulated before passing into the meter (Z5. The direct circuit to the meter or the i'n-y direct circuit through the cooling coil is con* trolled by the valves f', Z7 so that the cooling coil can be cut out or cut in to the circuit Whenever desired.-
By constructing and arranging the valve mechanism so that a constant raftiois maintained between the volume of liquid flowing through the main valvechamber b and that flowing through the by-pass Z the meter can be made toregister accurately the Whole amount of liquid Whether the liquid is l'oiving to the full capacity of the conduit or Whether only'a slight amount of li'quid is passing through and this Lmaintenance' oi a constant ratio between the main flow and the bypass How` is the characteristic fea# ture of this invention.
It W'ill be ii'oted that I have not underta'len to show details as to packings and stuling boXes which would Abe Within Cthe province of the ordinary mechanic.

1,'Th'e combination with the main valve chamber provided Withtapered ports, a by-'pas'sage provided with 'correspondingly tapered ports, a val-'ve piston seated in said valve chambeil and actuated automatically by the :pressure of thev liquid, a lay-'passage valve orcon'tjrolling the by-passage ports, means for regulating the action of the bypass'a'ge valve 'in accordance With the movement of said iirst mentioned valve, the bypassage being adjustable in relation to its valve, substantially as described.
