I, HEINRICH MEINECKE, Engineer, of the firm H. Meinecke Jun., Gabitzstrasse 90,
Breslau, Germany, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide generally an improved system of auto-
matically registering the quantity of water or other liquid passing through a meter,
but especially for the use of water works in detecting leakages and waste and
recording the quantity of water lost by such leakage or waste within a certain space
of time.
For the purposes of my invention I take any well known Liquid meter, the recording
dial of which I isolate and provide with projecting points at intervals, against which
the hand or hands of the meter must strike or slide in their rotative motion, thereby
closing an electric current (produced by a Battery or otherwise) which in passing
round an Electro magnet attracts an anchor or lever, the opposite end of which is
thereby moved towards a colouring or marking medium. Between the said anchor
or lever a slip of paper or a tape or other suitable material is caused. to movo
regularly by means of clockwork or some similar mechanism. In consequence of
the arrangement of the various parts as described, the action which takes place is as
follows: The liquid passing through the meter causes the hand to rotate and when-
ever the hand touches one of the projecting points, the electric current is closed,
causing a movement of the Anchor or Lever so that the paper or tape which is
kept in regular and constant motion by a clock or similar mechanism, will be brought
in contact with a medium that impresses a mark upon it. As the spaces between
the raised points on the meter dial correspond with a certain quantity of liquid
passing through the meter, and the paper slip or tape moves a certain distance
forward in a given time it follows that the quantity of liquid passed, through the
meter in a given time may easily be calculated from the length of paper passed or
tape and the number of marks impressed upon it.

Improvements in the Construction of Self-registering Water-meters
or Meters for other Liquids.
I HEINRICH MEINECKE of Gabitzstrasse No. 90 in the City of Breslau in the
kingdom of Prussia, German Empire do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
The object of my invention is to produce an improved, more portable apparatus,
for registering the quantity of liquid which passes through a meter in a given space
of time, than those now ordinarily used.
The manner in which I carry my invention into effect may be seen from. the
accompanying drawing.
The combined apparatus consists in the main of an ordinary water meter A, a
Battery B, a clockwork C, a magnet m with anchor n, and a disc D, which latter can
be kept in regular rotation by means of the clock work C, the transmission being "
effected in any ordinary manner.
The dial plate a of the liquid meter A is isolated from the meter itself by means
of a vulcanite or other isolating disc b. At regular intervals little knobs or pins c,
are fixed in the dial plate, such knobs or pins being generally made of platinum, of
which material the hand is likewise generally made. The hand in turning gets into
contact with the pins c, one after another, at each contact closing an electric current
by the element B. The current is made to pass through an electro magnet m, by
means of wires in the ordinary way, and every time that the current closes the
anchor n is attracted by the magnet. The anchor is balanced by the counterweight
and the spring z, and a set screw y serves to support it when out of action. The
counterweight a is movable, and may be adjusted as required. On the anchor is also
fixed a marking medium o, so that every time that the anchor is attracted towards the
magnet in consequence of the current closing a mark is made upon the revolving
paper disc. I arrange the clock work in such a manner that the disc moves once
round in a certain time, the disc being furthermore divided into degrees, for instance
so that each degree is equal to ten minutes and the disc making one revolution in one
hour:
The various mechanisms above described are most conveniently fitted into a box
so that it all is compact and readily portable, and when in use the meter is connected
with the pipes conducting the liquid, for which purpose the inlets and outlets E
and Fare provided. As soon as liquid passes through the meter the band d will be
caused to rotate and as it from time to time gets into contact with the pins c a mark
is made by the marking medium upon the disc D in consequence of the anchor
being attracted towards the magnet every time the contact between d and c takes
place. The fact of. the disc moving a certain distance round in a certain time it
follows that the apparatus records the quantity of liquid which passes through the
ineter in a given time.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. The arrangement for registering the flow of liquid in a certain time through a
water meter, consisting essentially of knobs or pins c, fixed in an isolated dial face
in such a manner that the dial hand, when rotating touches them thereby closing an
electric current.
2. In such instruments causing the quantity of liquid passing through a meter to
be recorded on a disc kept regularly turned by clock work, by means of an anchor
bringing a marking medium into contact with such disc every time the current is
closed as per claim 1.
Both substantially in the manner as and for the purposes described and substantially
as shewn in the drawing.
