IMPROVEMENT IN WATER-METERS.

Specification forming part of Letters Patent No. 140,73E, dated July 8, 1873; application filed July 17, 1872.

To all whom it may concern:

Be it known that I, ALBION M. ROUsE, of the city and countyr of St. Louis and State Of Missouri, have invented a certain Improved Water-Meter, of which the following is a specfication:

My invention relates to a water-meter in which the water acts upon two spiral propellers or sets of buckets on a shaft passing axially through a cylindrical water-way. My invention consists in -the combination of a fixed deflector with two propellers Or sets of buckets O11 the shaft so as tO balance the pressure of the water upon4 the shaft to overcome the end pressure and friction attendant on the use of a single propeller where the pressure is all in `one direction.

Figure 1 is alongitudinal section Of the meter. Fig. 2 is a transverse section through the saine at the line X X, showing the tube containing the vertical register-shaft and the register in elevation.

A is the induction or receiving port, and A the eduction or discharge port. B is the propeller-case. O is the propeller-shaft, whose conical ends turn in suitable adjustable center-screws l). Upon the propeller-shaft are bosses c, in which are secured the propellerscrews or inclined buckets E E', one Of which has a right and the other a left hand turn. These propellers may be made of any suitable form, either of extended curved win gs or plates, or of sets of detached buckets. F are fixed guide feathers or ribs which extend radially inward from the walls of the cylindrical water passage or way B', the said feathers pre venting the water from receiving a rotary motion from the reaction of the propellers upon it. The feathers or ribs may be straight with the water-way, or curved in an opposite direction to. the propellers. Bll are water-ways.

After passing through the induction-portA the water comes in contact with the deilector G, which divides the stream and turns an equal quantity to each propeller. The course ofthe water is shown by the arrows. H is a worin Or screw upon the main v shaft, said worm engaging a worin-wheel, I, upon the second Or vertical register-shaft K, which extends upward in a tube, L, and to the register M. The upper end of the shaft K may have a screwworm engaging with the first wheel Of the register. The register-case M and tube L are made air-tight, so that they may be made to contain air of suicient pressure to prevent water rising in the tube. The worm-wheel I is chambered in a case, N, which is so connected to the propeller-case B that the former case can be turned on the thiinble-coupling O concentric with the shaft O to enable the adjustment of the shaft K to avertical position, whatever the postion of the case B, the shaft C being horizontal in all positions of the case B.

My meter will operate if the iiow of water is reversed, viz., allowed to enter at A and discharge at A; but I prefer the arrangement before described.

`The deilector Gr may be inclined and have inclined channels g to give a rotary motion to the entering water before it reaches the pro-- pellers so as to increase its action upon them.

I claim as my invention- The combination Of the fixed deliector Gr and right-hand and left-hand scre\vpropellers E E on one shaft, C, to balance the water-pressure on the shaft, and cause a free rotation of the saine, substantially as described.
