FLUID-METER. I

To all whom it mag/concern.

Be it known that we, JOHN G'. Carrier and FRANK J.'- WAGNER, citizens of the United States, residing. at Erie, in the county of Erie, State of Pennsylvania, have invented a new and useful Fluid-Meter, of

which the following is a specification.

. provided a valve casing 1 adapted to be:,.

readily interposedinthe fluid pipefor cona duit, and having a partition 2 therein be -branch- 3 providedwith an outturned annuthrough the The present invention apper'tains to meters, and aims to provide a novel and improved meter whereby the amount of gas, air or other fluid flowing through. a pipe maybe determined and recorded with ap-' proximate accuracy. a 7 p a The object' of the invention, is'the provision of a deviceadapted to be interposed I in the fluid pipe or conduit, and

constructed and operable, that the-fluid'fin ich'is so flowing through ,the pipe or conduit will operate the indicating or-recording device according to the volume of fluid flowing ipe, and the pressure and velocity thereof? Y j It-is also .within the scope of the"- invention to provide a fluid meter which is comparatively simple and inexpensive in construction, which employs but few parts, which operates with little friction, and which operates in'a thoroughly practical, simple,and efficient manner. v

With the foregoing/andother objects in view which will ap ar as thefdescr iptionj prpceeds, the invention resides in the comblnation and arrangement of parts and in I the details of constructionhereinafter described and. claimed, it being understood that changes in the precise embodiment of the inventlon herein disclosedcan be madewithin the scope of what is claimed, without wise detachablysecured upon the upper end of the sleeve 6, and the recording gage 18 is departing from the spirit of the invention.

The invention is illustrated in its preferred embodiment in the accompanying ."-.provided"w1th concentric rmgs 21 which inay' be suitably graduated to indicate the volume of fluid under various pressures, or

drawing, wherein Figure 1 is a; vertical section of the meter. Fig.2 is a horizontal section taken on the line 2-2 of Fig.1.

In carrying out the invention there is tween itsends, and an upwardlyv projecting lar flange 4. The partition 2 is provided with an opening 5, which is tapered, the edges of the opening 5 being beveled to providea beveled valve seat.' The opening 5 and branch .3 are in alinement. f

v Specification of Letters Patent. Patented 11 119 20, 1916, Application filed May 13, 19 5. serial m. 27,914. i

'A sleeve 6 having an annular outturned flange 7 at one end is attached to the branch 3, the flange 7 being bolted or otherwise secured to the flange 4, and a disk or parti I tion 8 is clamped between the flanges ,4; and

7 of the branch 3 and sleeve 6, respectively, I

to close the and sleeve 6.

A stem. 9 is slidabl through the disk 8,

passage between thev ranch 3 and an inverted conical valve 10 is threaded or otherwise engaged to the lower. or inner end of the stem 9, and cooperates with the'- valve seat formed by the opening'5. The valve 10 is movable into the opening 5e to' seat snugly therein with the apex or oint of the valve projecting beyond the ower or free ends of the standards 11- and interf meshes with a rack 13' formed upon the upper endportion of the stem 9 above the .disk 8. A second and larger gear wheel 14 is carried by a shaft 14 between the stand ards 11 below the gear wheel 12 andinteIF" mesheswith the said gear wheel 12, and the shaft 14 projects out through-one side of the sleeve -6 andjcarries at its outer end, an upwardly projecting arm 15. The upper or free end of the arm 15 carrie'ga pen or marking element 16 which bears against a flat circular chart 17 carried rotatably by an ordinary recording gage 18, in order that the vertical chart 17will be rotated by means ofa suitable clockwork,

"A cap or cover plate 19 is bolted or othercarried by' the plate 19. The chart 17 is the like, the chart 17 has lines 22 intersecting the lines 21 and which may he graduated by suitable units. oftime, according to the velocityat which the chart 17 is rotated by the clockwork (not shown). A. In operation, supposing the casing 1 to be interposed in a flu1d pipe or conduit, so that the fluid flows from the left to the right, as seen-in Fig. 1, the fluid in passlng through 1 the c asin 1 will raise the valve 10, and the stem 9 w1ll thus beraised to carry the rack '13 therewith? The-rack 13 in engagingthegear wheel 12 will rotate the said gear wheel and thus will impart rotation to the gear wheel 14, whereby the indicating or recording arm 15 is oscillated. When the pressure or velocity of the fluid is great,'the

valve will be raised to a considerable distance, whereas when the pressure is low, the valve,10 will drop close to its seat. Consequently, the valve 10 will be raised proportionately to the pressure or velocity of the fluid, and the pen or, marking element 16 will'inscribe a line 23 upon the chart -17 which will indicate upon the chart the approximate volume of fluid flowing through the pipe at the various periods of time.-

From this line 23 the volume of fluid which i has passed through the pipe for a given time may be determined with considerable ac'curacy. 1 I

Due to the provision of the conical valve 10 and the beveled valve seat 5, the device will operate in a tho-roughly eflicient manner under various pressures of the fluid and the valve 10 will be lifted properly under various conditions. The present device thus provides a pressureand voluetric meter of simple, yet effective opera 'on. It will be noted that the arm vmay be employed as an indicator or pointer, or may be 'em-.

ployed for carrying oneorv more marking elements for cooperation with one or more charts according to the nature of measurements desired. The valve 10 is-sufiiciently heavy, or acts as 'a Weight, whereby it will ,4 i move against the fluid flowing through the. x openingfi, as will be apparent, and it will also be noted that the disk or partition 8 I, prevents the fluid from 'escaping. The

gearing is confined within the sleeve 6 to be housed thereby, and the several parts of the structure may be readily separated and assembled. 4

The other advantages and capabilities of the present invention will be obvious to those skilled in the art, without further comment being necessary.

Having thus described the invention, what is claimed as new is In a fluid meter, a casing having a partition therein and a branch, the vpartition a shaft projecting through one side of the sleeve and journaled to said bracket, an

indicating arm carried by the outer end of said shaft, the stem having a'rack within thesleeve, gearing carried by said bracket and con'nectingfsaid rack and shaft and a rotatable flat vertical chart mounted upon the,said cover and adapted to be clock driven,- the free end of said arm having a' marking element cooperable with said chart.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signaturesjn the presence of two witnesses.
