To all whom t may concern.'

Be it known that 1, FRANZ ANTON HUB- BUCH, of Furtwangen, in the Grand Duchy of Baden and German Empire, have invented a certain new and useful Improvement in vWater-llieters, (for which I have obtained Letters Patent in Austria, No. 1,700, dated May 14:, 1805; in Hungary, No. 2,682, dated May 2, 1805; in Belgium, No. 115,236, Ydated April 22, 1805; in France, No. 216,984-, dated April 29, 1805; in Great Britain, No. 11,22%, dated June 7,1895; in Switzerland, No. 10,298, dated April 15, 1895; in Italy, XXX, 38,982, LXXVI, 281, dated June B0, 1895, and iu Germany, No. 83,598, dated December 16, 18%,) of which the following isa specification, reference being had to the accompanying drawings.

rlhis invention relates to water-meters.

The adjustment of water-meters, for securing a correct measuring action of the same, is at timesa very tedious matter. The means heretofore devised for rendering such adjustment possible and for effecting the said adj ustment with promptness and dispatch whenever required were in most cases not based upon scientific principles and would very often impair the sensitiveness of the watermeters. The said means or devices are usually provided within the water-inlet, and they would thus act to reduce the speed of movement of the water previously to its being measured, or they would allow a portion of the water to pass through the measuringchamber of the meter without being measured at all. It is obvious that a device or arrangement which would admit of a gaging or adjusting of the action by regulating the flow at the discharge would under all circumstances be preferable to the devices or arrangements heretofore employed, as referred to above.

The object of this invention is to provide a construction of water-meter having this improved mode of adjustment; and the invention therefore consists in the arrangement and combination of parts more fully hereinafter described, and shown in the accompanying drawings, in which- Figure lis a central vertical section on the line A B of Fig. 2 of a water-meter provided with my improvement. Fig. 2 is a horizontal section on the line C D of Fig. 1. Fig. 3 is a horizontal section on the line E F of Fig. 1 with the winged Wheel removed. Fig. e is a sectional elevation of a detail on the line G H of Fig. 8.

The general construction of a Wheel watermeter being well known does not require to be particularly here described.

The water freely enters the measuringchalnber ,z in a tangential direction through the openings m m, thereby imparting rotary movement to the shaft XV of the measuring'- wheel f. (See Fig. l.) By means of curved channels 7;. 71;, provided in the inner top portion, and by similar channels p p, provided in the bottom of the casing, the measured water is conducted toward the said shaft and caused to pass through the aperture d and openings n n. to the place whence it is taken for use. The channels k 7o, as well as the channels p p, are of uniform cross-section throughout. ln being driven from the peripheral portion of the measuring casing toward the aperture (l the water, by its swell, acts to disturb the free movement of the measuring-wheel.

It is obvious that by allowing a portion of the measured water to escape into the regular discharge-conduit near the circumferential portion of the measuring-casing the measuring-wheel may be caused to rotate more freely, and that the result of the measurement may thus be altered. To this end holes Z) b are bored in the raised portions formed by and between each two channels 7o k, (see Fig. 1,) and above the said holes is provided a ring S, the latter resting in a correspondingly-shaped annular recess and being provided with openin gs a d, corresponding with the holes l) b above referred to. By means of an arm or index X, provided on the said ring, (see Fig. 2,) the latter may be rotated more or less, so as to alter the positions of the openings a a with regard to the holes l) b, and the latter may thus either be closed entirely or opened to any desired width. lt will thus be seen that by a suitable adjustment of the position of the said ring, which 1 shall hereinafter re- IOO fer to as the gaging-ring, a portion of the measured Water, after having taken part in the movement of the Win ged measuring-wheel, may be discharged into the conduit without being forced through the aperture d, and Without, on its Way to this aperture, hindering the movement of the Winged measuring-Wheel.

If the Wheel-train of the counting mechanism, which is in the usual and Well-known manner in closed in the chamber M, and therefore not shown in the drawings, is so arranged that in a particular apparatus the result of the measurement would differ by about ten per cent., then this may be easily corrected by moving the arm or index X, and thereby turning the gaging-ring S. The said ring is retained in its position by the eight feet forming the connection between the chamber of the counting mechanism and the measuringcasing.

A rough or preliminary adjustment may also be effected by means of the rin gu., the latter being shown in position Within the Watermeter casin g in Fig. 3, While Fig. il: shows the said ring removed. By turning this ring a resistance may be introduced in the channels p p, so that the oW of Water toward the center will thereby be impeded. The channels p p, provided in the bottom 7L of the casing, may either be curved in the direction of the ow of Water or in the opposite direction. By this means and by selecting the proper degree of curvature for the channels I may cause the Water-meter either to lag behind gradually or to advance in the indication from the largest to the smallest passage of Water.

Having thus fully described my invention,

what I desire to claim and secure by Letters Patent is- 1. In a Water-meter, the combination of the measuring-casing F' having tangential inletopenings m curved channels 71; in the inner top portion of said casing with vertical passages b between said channels, a rotatable ring s arranged in the cover of the measuringcasing above the passages Z) and provided with openings a, and the measuring-Wheel f having its shaft w extended through an aperture d communicating with outlets n., substantially as described.

2. In a Water-meter, the combination of the measuring-casing z having tangential inlets m, curved passages p in its bottom controlled by a perforated adjustable ring u, and provided in the top with a central aperture d, curved channels 7a and vertical passages tintermediate the said curved channels, a perforated rotatable ring s to control said vertical passages b, and the measuring-wheel f, substantially as described.

3. In a Water-meter a number of curved channels, such as p p, provided in the bottom of the measuring-casing, and an adjustable ring, such as u, capable of being rotated with relation to the said channels, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

FRANZ ANTON HUBBUCII.
