LIQUID METER.
Application filed September 12 1923. Serial No. 662,259.
To all whom it may concern:
Be it known that I, VVILLY PETERSSON, a citizen of the German Republic, and resident of No. 11 Forss'mannstn, Hamburg, in
6 the Republic of Germany; have invented a new and useful Improved Liquid Meter, of which the following is a specification.
The presentinvention relates to a liquid meter provided with an inlet and outlet valve alternately opened and closedby a fioat to control the admission of liquidto and its escape from a measuring chamber, a registering apparatus or counter being in opera tive connection with the'valves and means being provided to prevent a premature ae tu'ationof the valves underthe rise and fall of the float.
Special objects of the invention are to render more eflicient, serviceable and durable in operation devices of the kind referred to.
WVith these ends in view the invention consists in the novelcombination, arrangement and adaptation of parts, all as more fully hereinafter described, shown vin the accompanying drawings and then specifically set out in the appended claim.
In the drawing is shown by way of example one. mode of carrying into practice the invention, the figure representing a vertical section through the improved liquid meter.
The measuring chamber '1 preferably in the form of a cylinder or barrel is connected by the'fiange 2 to the top edge of a lower collecting chamber 3, so that it extends into the latter as shown. At' the top end, the measuring chamber 1 is closed by the bot tom f a casing 5 secured to the flange 2.
Centrally in regard to the measuring chamber 1 a vertical valve stem. 6 is arranged, which is conically shaped at its lower end to form a needle valve 7 in connection withthe valve seat 8 in the bottom of the measuring chamber 1. The upper end of the valve stem 6 extends through and is rectilineally guided in a hole 9 in the top 4 of the measuring chamber 1.
The liquid'to be measured is supplied to the chamber 1 by a pipe 10 in connection with the casing 5, communication between this pipe 10 and the measuring chamber 1 being established and interrupted by means of the valve 11 having its seat in a hole of the top 4. This inlet valve 11 is in operative connection with the valve stem 6 of the out let valve'7. As shown in the drawing the inlet valve 11 is acted upon by a two armed lever 13 having its'fulcrum provided by a pin seated ina bracket 12 fast to the lower surface of the toph Thesecond arm ofthe lever 13 is bifurcated and engages a pin 14 fast to and projecting from the valve stem Gasshown.
The valve stem 6acts as a guide upon which an annular float 15 is slidably positioned in such a manner as to move longitudina'lly of the measuring chamber 1 as the level'of the liquid therein rises and falls. Abovethe needle valve-7 the valve stem 6 is hollow and serves to accommodate and guide a rod'26, which projectsbeyond the top end of the valve stem. 4 Above and below the. float 15 thehollow valve stem 6 is provided with slot openings. Pins 16 and 17 fast to the rod 26 project through these slot 0 enings so that they limit the rise and fa lofthe float 15 on the valve stem 6.
In descending the float 15 contacts with the pin 17 and exertssuflicient pressure to move the rod 26' downwardly inside the V valve stem 6. This downward movement of the rod 26 serves for actuating a registering/apparatus or counter in a manner to be fully described later on.
7 "After the rod 26 has reached the limit of its downward movement inside the valve stem 6 "the'continued pressure of the descending float'15 on the pin 17 forces the valvestem6 downward until the needle valve 7 reaches its seat 8 and cuts off the escape of liquid from the'measurin'g chamber 1.-
This downward movement of the valve stem 6-is translated by the operative connection between the pin14c and the two armed lever 13 into an upward movement of the inlet valve 11 so that the supply of liquid from the pipe 10 to the measuring chamber 1 is established while the outlet valve 7 is closed. Admission of liquid'to the measuring chamber 1 continues until the rising level lifts thefloat 1-5suflicientlv to contact with the pin 16, thereby raising the rod 26 and finally the valve stem 6. By raising the rod 26 and the valve stem -6 the outlet valve 7 is opened, whereas theinlet valve 11 is closed, the twoarmed lever 13 by its operativeconnectionwith 'the valve stem 6 swinging back into its initial position allowing the valve 11 to automatically close against its seat and thus to cut off the supply of liquid to the measuring chamber 1. 7
The pipe 10 effects connection with any desired reservoir holding liquid to be drawn 7 mentinlet and; outletvalves 11 and 7' maybe regulated according to desire or requ re- ,7 Inforder to register or count the number of charges passed through the measuring chamber 1 the following novel arrangement is provided." o
Inside thecasing-5 a spring motor-19 is housed which maybe wound up periodically by means of an externally accessible key; in the usualflmanner. =The spring motor 19 drives atrain of wheels 20, the last wheel ofwhich actsas an escapement being formed bya disc 21v having a locking tooth 22 on its circumference, ,An anchor 24 oscillating on a pin 23 partly vsurrounds the circumference of the disc 21, arresting the rotation of the latter by means of pallets at its two extremities gwhich alternately engage the tooth 22. 1 Eachactuation-ofthe anchor 24 liberates the disc 21 to perform a half revolution whereupon it is arrested again by the pallet: on. the second extremityof the anchor 24; engaging the tooth 22. Thefan l chor 12 i has a lever arm 25oprojecting beyondthe pin 23, said lever arm being in operative connection with the rod 26 atvthe upper end issuing fromthe valve stem 6. The upward and downward movement of the rod 26 caused by the rise and fall of the float-.15 oscillatesthe anchor 25L, so that the disc 21 is liberated to performa half revo,
lution during the upward as well as during the downward movement of the rod 26. A
In order to prevent a premature downarmed lever. 33 is pivotedjaround' apin 32o inthe casing 5, said lever being bifurcated at one end and engaging with this end a pin 34 projecting frornthe .valvestem 6,
whereas, the other end of this lever abuts against a cam 35 in fixed connection with The registeringapparatus or the escapement 21. During each complete revolution ofthe escapement-21 this cam 35 acts'on the lever 33 in such a manner that the valve stem 6 is retained in its elevated position while the float 15 starts its descent with the fallof the level in the measuring chamber 1. When the rod 26 is sufficiently moved downwardly by the float 15 contactthe disc 21' under the influence of thespring motor 19, the cam 35 partaking in this rotation liberates the lever 33 at the proper moment for closing the outlet valve 7.
' The improved liquid meter is'specially ,ing with the pin 17 to start the rotation of adapted vfor use with petrol orgasolene tanks,-it may however be utilized in connectionlwith any other liquidto be draw of]? in predetermined quantities, r
I wishit to bedistinctly understood, that I do notlimit myself to the precise construction shown,jseeing that various modifica o tions may be carried out in the adaptation of my improved liquid meter to the several kinds of application and I therefore reserve the right toa-ll such modificationsthat properly fall within the scope of the followin claim. a
What I do claim as my invention and desireto secure by Letters Patent is A liquidmeter comprising an upwardly opening measuring chamber provided with an outlet, a register casing adapted tobe secured. to the open end of said chamber to form a top therefor and provided with an inlet leading to said chamber, valves; for
controlling said openings, means connecting said valves whereby too-open one valve and close the other to alternately fill and empty the measuring chamber, a float in said chains ber, spring impelled mechanism in the reg ister casing, gearing adapted to be driven by said mechanism and including an escapement disc and cam adapted to rotate in unison, mean's connected to the valve connect:
ing means and engagingthe cam for operatmg the valves upon rotation of said cam,
means in engagement with said disc to con-,
trol the rotation thereof, means connected to the lastnained means adapted to beeperated by the float as it rises and falls with the liquidlevel in the measuring chamber for controlling the rotation of the discand aregister in the casing adapted to bedriven' by the gear trainofor indicating the volume of liquid passing through the meter.
