Inférieure, France, Inventor, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a water-meter, which will enable any
householder, or user of water, to know what quantity of water he or she draws from
the supply, daily weekly or monthly.
My meter, which may be applied to any water supply system, is provided with a
regulating tap, to be placed in the pipe, above my meter.
The meter itself, is composed of a protecting case, with an indicating dial, and an
interior mechanism.
This mechanism is very simple and consists substantially of a cylinder (of a piece
with the water-pipe) through which passes an axle, carrying a toothed wheel with
interior worm.
This toothed screw-wheel, operated by the flow of water striking against its
blades, transmits its movement to a toothed-wheel, placed outside the cylinder.
This wheel engages the wheel of the meter the movement of which is transmitted to
the whole apparatus by a set of gear-wheels, of determined multiplications, the
axles of which move the three needles on the dial. The large needle pivoted, in the
centre of the large dial, on its axle, serves to indicate the consumption in litres;
the small needle fixed on its axle, to the right of the central axle, indicates
hectolitres, and the other small needle indicates cubic metres.
Dated this 19th day of March 1897.

I, AUGUSTE GUILBAUD, of Rue de Nantes, St. Nazaire, Department of Loire
Inférieure, France, Inventor, do hereby declare the nature of this invention, and in
what manner the same is to be performed to he particularly described and
ascertained in and by the following statement :-
The present invention concerns a water-meter, the object of which is to enable
small householders to check the daily or monthly supply of water.
In the annexed drawing a form of construction of my system of water-meter is
shown:
Fig. 1 is a front view of the meter connected with a water-pipe.

page_text: Fig. 3 shows a plane view of the meter with its dial, and
Fig. 4 is a plane view of the wheel work, the dial being removed.
This meter is composed of a projecting cover O provided with an indicating dial X
and containing the mechanism and a hollow cylinder B forming a body with the
water-pipe A and traversed by an axle E' bearing, at its lower part, a cylinder E
with interior screw, and, at its upper part, a toothed wheel C.
The screw under the action of the energy of the water striking against the blades,
adopts a rotary motion which, by means of the toothed-wheel C is communicated to
the wheel D; this latter, through the intermediary of toothed-wheels with
determinate multiplications, moves three hands G H I fixed to the axles G¹ H¹ I'.
The large hand G serves to indicate the consumption of litres and the small
hands H and I respectively mark the hectolitres and the cubic meters.
tube b starting from the lower part of the cover O at the point where the axle E¹
passes through the side P serves to catch the water that might drop into this covering
and leads it into the outlet pipe at M.
A small
My water-meter is intercalated in the water-piping and provided with a plate N
which allows it to be fitted to the wall.
Having now particularly described and ascertained the nature of may said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1) An improved water meter for the use of small householders the said meter being
fitted to the water-pipe and indicating the consumption of water by means of three
dials one for the litres, the second for the hectolitres and the third for the cubic
meters and distinguished by a cylinder with interior screw, fixed upon an axle and
receiving under the pressure of the water coming from the water-pipe a movement
which it communicates through toothed wheels which through the intermediary of
calculated multiplication gearings, moves the hands on the dials; also by a small
tube which leads the water accumulated in the envelope of the meter to the outlet
pipe, substantially as described and shown.
2) An improved water meter substantially as described and shown.
