y v Application led December 19, 191'?.` Serial 110.207,809;

l'cisco and'Sta-te of California, have invented new and useful Improvements in Liquid- Meters, of wlich the following is a speclflcation. I

The object of the present invention" is to provide a simple, inexpensive, compact 'and' accurate means for reglsterlng'the maghi` tude of the flow of the flowing l1qu1d,'wh1ch is adapted for measuring the ow of liquids of all kinds In the accompanying drawing, Figure is a plan view of a box-like casin of my nn"- `proved liquid meter, the "mec anisln non. mally therein beingy removed; Fig. 2 1s a broken plan view showing` said parts partly in, section; Fig. 3 is a view 'slmllar to Fig. 2 showing said parts'in the same manner but in positions different from thosein Fig. 2

Fig.` 4 is a transverse .vertical section through the meter.; Fig. 5 a broken plan. v1ew thereof.

Referring to the'. drawing, l1 indicates a i base to which is bolted the lower portion 2 of a casting,` the upper portion of which is in the form of a rectangular box 3, the top of whichbox is closed by a removable cover -4 bolted down thereon tight,- and inclosing therewithin a rectangular hard rubber slide piece 6. Said slide piece 6 consists of four walls, of which two, 7, are longer than the 'other two, 8, and fit closely against the long ,and an'outlet pipe `12. The conduit 9 disas shown at .'13, in the 'charges centrallgt ox-shaped portlon of the bottom of the casting, while the conduit 12. opens in the bottom of said box-shaped portion at a distancey from the center, and communicates with a circular groove 414 formed in the bottom`- of said box-shaped| portion.

`Slidable in said box-shaped part 3 of the ,casting is a hard rubber meter-head 15 which is likewiserectangulanin form and of a length to fit exactly between the end -walls 8 of the slide' piece 6. The width,

u however, of said meter-heady is less than the width of the slide to enable it to slide transversel in the slideV iece 6. The meter-head bottom of the box 3 and the under surface of the cover 4. Centrall in theunder-side ofthe cover is a cylin rical recess 16 in which' is fitted a disk .17, from the center of 'which a shaft 18 extends upwardly through a bearing 19in the cover, a hard rubber bushin 20 being interposed between. the shaft and lts bearin From the disk depenl s eccentrically a pin 21 which passes throu h a central hole in the meter-head. It is evi ent that, if the meterhead is given a 'motion of revolution about thecenter of the disk, the shaft 18 will be rotated. l

The meter-head is formed with four equally spaced conduits 22. Each conduit' leads from the bottom of the meter-head first directly upward and then outward in a spiraldirection, the spiral portions 23 of lsaid conl duits Increasing in width outwardly and ter minating in themiddle of the sides -of the meter-head. The length of the spiral is such that the conduit turns through a right angle from its beginning inlet end 'of each conduit lies directly between the center of the meter-head and one of its straight sides and 4the conduit termi; nates in the'middleof aside which is next adjacent to the aforesaid side. By reason of the eccentric relation of the pin 21 and the shaft 18, the meter-head will always be eccentric to said shaft 18, 4and the smaller to its end. The 1 end of one conduit 22 will always be in registerwth a-portion of the groove 14 whl `the smaller end of the opposite conduit 22 will always bein register with the one-half of the-.hole 13 which is farthest from said portion of the groove 14. supposing the. parts to bein the position in which the entrance or narrow end of one of the conduits 22 is' nearest a long Vside of the" slide piece 6, thenthe liquid will flow through hole 13 into the smaller end of one of said conduits 2 2 and will iow outward in said l` conduit 22 to the outer end thereof, then ico =the inlet pipe 11 and inlet conduit 9 and site end of the box through the corres onding )ort 24 in the adjacent wall 8 an into the larger end of the spiral portion 23 of the opposite conduit 22 and out through the smaller end thereof and into the groove 14 and ,so into the exhaust pipe-12. By the pressu e of the liquid the slide piece is moved from't rst-named end toward the secondnamed end.

The meter-'head is also moved with the slide frame in a longitudinal direction, and by'reason of the 'fact that this motion is controlled by the pin 21 which enters the central hole in the meter head, it. cannot move in a straight line in a longitudinaldirection, but must move also in a transverse direction, and thus a circular motion is imparted to the center of the meter-head,

which .causes the communications between the first-named pair of conduits 22and the hole 13 and groove 14 respectively to be diminished, and communications to beopened and enlarged between said hole 13 and groove 14 and the other pair of said -conduits 22', so that pressure liquid is now flowing from the hole 13 into both of the smaller ends of said conduits 22, and liquid is flowing from the smaller ends of the opposite conduits 22 to the groove 14:. Part of the pressure liquid now lows through one of the other conduits 22 and imparts pressure in af transverse direction against one of the longitudinal walls of the metery head, and, conversely, liquid from the opposite side of said meter-head flows inwardly vthrough the .spiral conduit 22 into the.

groove 14' and discharges, outwardly. vThe meter-head -is thus pressed in a transiferse direction so that when liquid flows from: the hole 13 through twovadjaceut short ends of the conduits, vpart of the How of liquid has the effect of pushing the meter-head transversel and part has the electof-pushing the sllde frame longitudinally, in all cases, however, giving to the meter-head a lcircular motion' of revolution about the shaft 18. 'It will be seen Ethat in this way a constant rotation is imparted to said shaft. The long sides 7 of thes'lide piece 6 are cut away at top and bottom, as shown at 25, to reduce their height to. less than vthat of the `outer ends of the conduits 22.

so that the liquid is in contact with the ad-l jacent walls of the box 3.

This motion of rotation of said shaft may be utilized in any manner lto'deter'mine the; rate of flow of the fluid-.in ythe meter. Foryinstance,as `shown inl Fig. 5,-5the Shaft 18 may carry a staple 26 which meshes with a gear wheel 27 upon va shaft 28 carrying also a spiral gear wheel 29 which meshes with a spiral gear wheel 31 on a shaft 32 ,which actuates mechanism 33 for registering the amount of liquid passed through the meter.

1. In a liquid meter, a rectan ular casing, a rectangulal slide piece slida le longitudinally in the casing and having walls, ofvwhich two opposite fit snugly against-the adjacent walls of the casing' and the others are spaced from the other walls thereof, a rectangular meter head slidable transversely in the slide piece and having conduits each opening at its inner end in the bottom of the meter head, and extending in an approximately 'spiral form through a quarter turn and opening vat its outer end in a side of the meter head, the bottom of the casing having therein inlet and outlet conduits, their inner ends terminating respectively `in a hole, and in a conduit spaced from said y ing, a'` recessed top therefor, a .rectangular slide piece-'slidable longitudinally 'in the casing and havingwalls,4 of which two opposite fit snuglyagainst the adjacent walls of the casing and the others are spaced from the other walls thereof, a rectangular meter head slidable transversely in the-Slide piece and having conduits each opening at its inner end in the bottom of theI meter head 'and extending in an approximately spiral form 'through aquarter turn and opening at Vits outer end in a side of the meter head, the bottom of the casin-ghavingtherein inlet and; outlet conduits, their inner ends terminating respectively in a. hole, and in a conduit spaced from said hole, in the bottom of the casing, inlet and outlet pipes connected with the-outer ends of. said inlet and outlet conduits respectively, a disk in the recess in the top of the casing, a shaftV extending through the top of the casing and connected to the center ofthedisk, a c rank pinv eccentrically secured to 'the disk and rta'tably connected with said meter head, and registering means outside the casing, op` eratedby the rotation of Said shaft.
