An Improved Water Meter..
1, REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street Strand W.C. London Civil Engineer do hereby declare
the nature of this invention a communication to me from abroad by Antonio
Eduardo Balaciart of 27 Rue des Tallers Barcelona in the Kingdom of Spain
Engineer and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:--
This invention consists in a meter for measuring the supply of water and the
object of the invention is to produce a meter thoroughly efficient in action but of
simple and inexpensive construction.
The improved meter is illustrated in the accompanying drawings in which
Fig. 1 is a side elevation of the outer case.
Fig. 2 a diagramatic plan view thereof.
Figs. 3 and 4 are vertical sections.
Fig. 5 is a detail view of the valves.
Figs. 6 and 7 are detail views of the counter.
The invention consists principally in the valve mechanism by which the water is
let into the upper and lower part respectively of a cylinder so that the movement
of the piston therein may be utilized to measure the quantity of water which has
passed into the cylinder. As completed the apparatus is enclosed in a casing of
light galvanized iron (Fig. 1) with inlet A. and outlet D for the water pipes, and
the series of dials of the counter on its face, covered by a glass window or suitable
cover.
Referring more particularly to Fig. 4, the cock 1 which is of the rotary kind is
provided with two passage ways in different planes so that in the one position of the
cock water passes from the inlet A to the inlet pipe A' which issues at B into the
bottom of the cylinder G', and in the other position of the cock the water passes
from the same inlet A to the inlet pipe E by which it enters the upper part of the
cylinder G at E¹. On the other side in the same axial line with the cock 1 is the
outlet cock 2, which has likewise two passage ways in different planes, so that in
the one position of the cock 2 the water may pass out from the upper part of the
cylinder G at C through the pipe C' into the outlet D, and in the other position
of the cock 2, the water may pass from the lower part of the cylinder G' at F into
the pipe F to the outlet D. The spindles S S of the two cocks 1 and 2 are
connected together by the sleeve M which carries a two armed or balance lever J.
This sleeve therefore if turned by movement of the lever J moves both
cocks 1 and 2 simultaneously so that the water passes alternately into the upper
and lower parts of the cylinder G', and the water previously therein passes out
simultaneously alternately from the lower and the upper space, that is to say the
spaces on the opposite sides of the piston G in the cylinder G. This piston is
packed with felt to slide easily in the cylinder G. The piston rod N passes
through a stuffing box O and carries the rack P with rack teeth on each face, the
one set of teeth gearing with the pinion T by which the counter is operated as herein-
after described, the other set of teeth engaging with the pinion Q carrying on its
side the tappet H. As the piston G moves under the pressure of the incoming
water, the pinion Q is revolved in the corresponding direction by the rack P.
The tappet moves the arm V of the hammer I and lifts the hammer until the latter
overbalanced falls upon the lever J and rocks the lever against the rubber buffer
block K just as the piston arrives at the end of its stroke. This action rocks the
cocks 1 and 2 and the inlet of water is changed to the other end of the cylinder.
The piston moves back and the pinion Q with tappet H rotating in the contrary

Figs. 6 and 7 are detail views of the counter.
The invention consists principally in the valve mechanism by which the water is
let into the upper and lower part respectively of a cylinder so that the movement
of the piston therein may be utilized to measure the quantity of water which has
passed into the cylinder. As completed the apparatus is enclosed in a casing of
light galvanized iron (Fig. 1) with inlet A. and outlet D for the water pipes, and
the series of dials of the counter on its face, covered by a glass window or suitable
cover.
Referring more particularly to Fig. 4, the cock 1 which is of the rotary kind is
provided with two passage ways in different planes so that in the one position of the
cock water passes from the inlet A to the inlet pipe A' which issues at B into the
bottom of the cylinder G¹, and in the other position of the cock the water passes
from the same inlet A to the inlet pipe E by which it enters the upper part of the
cylinder G at E¹. On the other side in the same axial line with the cock 1 is the
outlet cock 2, which has likewise two passage ways in different planes, so that in
the one position of the cock 2 the water may pass out from the upper part of the
cylinder G at C through the pipe C' into the outlet D, and in the other position
of the cock 2, the water may pass from the lower part of the cylinder G' at F into
the pipe F to the outlet Ď. The spindles S S of the two cocks 1 and 2 are
connected together by the sleeve M which carries a two armed or balance lever J.
This sleeve therefore if turned by movement of the lever J moves both
cocks 1 and 2 simultaneously so that the water passes alternately into the upper
and lower parts of the cylinder G', and the water previously therein passes out
simultaneously alternately from the lower and the upper space, that is to say the
spaces on the opposite sides of the piston G in the cylinder G. This piston is
packed with felt to slide easily in the cylinder G. The piston rod N passes
through a stuffing box O and carries the rack P with rack teeth on each face, the
one set of teeth gearing with the pinion T by which the counter is operated as herein-
after described, the other set of teeth engaging with the pinion Q carrying on its
side the tappet H. As the piston G moves under the pressure of the incoming
water, the pinion Q is revolved in the corresponding direction by the rack P.
The tappet moves the arm V of the hammer I and lifts the hammer until the latter
overbalanced falls upon the lever J and rocks the lever against the rubber buffer
block K just as the piston arrives at the end of its stroke. This action rocks the
cocks 1 and 2 and the inlet of water is changed to the other end of the cylinder.
The piston moves back and the pinion Q with tappet H rotating in the contrary

page_text: direction again lift the hammer I until it is overbalanced and falls on the other arm
of the lever. J returning this lever and with it the cocks 1 and 2 to the previous
position.
The delivery of the cylinder being known, for instance one gallon for each
double stroke, the counter is correspondingly made. On the shaft V' of the
pinion T is the disk X with the pivoted balanced or spring pawl Y thereon. As
the disk X revolves back and forth with each stroke of the piston G. this pawl Y
moves the ratchet wheel Z through the distance of one tooth. The train of
wheels Z' gives the multiples of 10, each wheel revolving at one tenth the speed
of the previous wheel in the series. The arbors of the wheels Z carry the index
fingers which indicate the sum on the dials of the counter.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :
In a water meter
1. The combination with the cylinder G having the piston G therein, of
the cock 1 with two passage ways adapted to be rotated to feed the water
alternately to the one and other end of the cylinder substantially as described.
2. The combination with the said cylinder and cock 1, of a second cock 2 having
two passage ways and adapted to be rotated to allow the water to pass out of the
cylinder alternately from the one and from the other end thereof substantially as
déscribed.
3. The combination of the two cocks 1 and 2 with the sleeve M with lever J,
the hammer I lifted by the tappet H on the pinion Q actuated by the rack P on
the piston rod, the piston G on said rod, and the cylinder G¹the whole arranged to
control the flow of water as described.
