1, LEON LENAERTS, of Brussels in the Kingdom of Belgium, Gentleman, do hereby
declare the nature of this invention to he as follows:-
This invention relates to apparatus whereby stop cocks such as those on gas meters
can be conveniently worked from a distance as for instance from several apartments
or floors of a building.
For this purpose a disc or plate, which is attached to the gas or other pipe by
means of a strap embracing the latter, carries a grooved pulley that fits either directly
or by means of a socket or sleeve on to the plug of the cock that is to be worked, so
that the rotation of the pulley will effect the turning of the cock.
The pulley is secured in position by a cover or plate having arms that are bolted to
the first named plate, so that the pulley is situated between the two; the cover carries
firstly two small guide pullies situated in the same plane with the main pulley and
secondly two other guide pullies on a swivelling bracket, whose axes are at a right
angle or any other adjustable angle to those first mentioned. Thus a pitch chain
passed round the main pulley (which has studs in its groove) passes thence first over
the two guide pullies in the same plane therewith and then over the two other guide
pullies, so that by adjusting the position of the latter the chain may be led away from
the apparatus in any desired direction.
Beyond the apparatus the two ends of the chain are attached to two wires or wire
cords, well stretched, that are led over guide pullies or by bell cranks to the apart-
ment where the regulation is to be effected; here there is provided a plate having
two rows of studs or hooks, each cord being hooked on to one or other stud of each
Thus when the one cord is pulled so that its end is hooked on to the one end
stud of the one row, the cock will have been turned full on, and the other cord will
be hooked on to the opposite end stud of the other row. On pulling this cord so as
reverse the position of the two on the plate, the cock will have turned quite off, wbile
row.

page_text: by bringing the two cords into intermediate positions on the studs, the cock will be
turned more or less on or off. In some cases I provide for an electrical indication of
the turning on or off of the cock, by connecting to the beforementioned cover of the
apparatus the one terminal wire of a circuit including a battery and an electric bell
or other signalling apparatus, the other terminal being connected to an insulated
contact stud on the cover. The main pulley is provided with a contact spring which,
when the cock is entirely closed, makes contact with the contact stud and closes the
circuit so as to give a signal, which is intercepted as soon as the cock is opened to.

page_text: I, LEON LENAERTS, of Brussels in the Kingdom of Belgium, Gentleman, 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 :—
This invention relates to improved apparatus whereby stop cocks, such as those on
gas meters, can be conveniently worked from a distance as, for instance, from several
apartinents or floors of a building.
The construction of the apparatus will be readily understood on reference to the
accompanying drawings, in which Fig. 1 shews a side view of the apparatus, Fig. 2
a front view, Fig. 3 shews the mode of fixing the apparatus, and Fig. 4 shews the
plate situated at the locality from which the regulation is to be effected.
A disc or plate N, which is attached to the gas or other pipe by means of a strap L
embracing the latter, carries a grooved pulley D that fits either directly or by means
of a socket or sleeve X on to the plug of the gas supply or other cock that is to be
worked, so that the rotation of the pulley will effect the turning of the cock.
in
The pulley is secured in position by a cover or plate K having arms that are
bolted to the plate N so that the pulley is situated between the two; the cover carries
firstly two small guide pullies B B situated in the same plane with the main pulley D
and secondly two other guide pullies on a swivelling bracket y, whose axes are at a
right angle or any other adjustable angle to the pullies B, the bracket being carried
by a plate E, that is provided with two or more holes for mounting the frame
different positions thereon. A pitch chain passed round the main pulley (which has
studs in its groove) passes thence first over the two guide pullies B B and then over
the two guide pullies at y, so that by adjusting the position of the latter the chain
may be led away from the apparatus in any desired direction. The cover K can also
be moved into any desired position on the disc N for bringing the guide pullies into
any convenient position for leading off the communicating chain or cord; for this
purpose the disc N is provided with a number of bolt holes round its circumference
to which the arms of K can ba fixed. The cover K is also secured to the disc by a
notched projection M fitting on to the edge of the disc.
Beyond the apparatus the two ends of the chain are attached to two wires or wire
cords, well stretched, that are led over guide pullies or by bell cranks to the appartient
where the regulation is to be effected; here, there is provided a plate F, having two
rows of studs or hooks, each cord being hooked on to one or other stud of each row.
Thus, when the one cord is pulled so that its end is hooked on to the end stud of the
one row, the cock will have been turned full on, and the other cord will be hooked on
to the opposite end stud of the other row as shewn. On pulling this cord so as to
reverse the position of the two on the plate, the cock will have been turned quite off,
while by bringing the two cords into intermediate positions on the studs the cock will
be turned more or less on or off. In some cases, I provide for an electrical indica-
tion of the turning on or off of the cock, by connecting to the cover K of the apparatus

page_text: the one terminal wire G of a circuit including a battery and an electric bell or other
signalling apparatus, the other terminal G' being connected to an insulated contact
stud O on the cover. The pulley D is provided with a contact spring which, when
the cock is entirely closed, makes contact with the contact stud at O, and closes the
circuit so as to give a signal, which is intercepted as soon as the cock is opened to
the smallest extent.
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 :
1. Apparatus for working gas and other stop cocks consisting of the plate N, wheel D,
cover K, guide pullies B and y, operating in combination with the regulating plate F
and communicating cord wire or chain, substantially as herein described.
2. The combination with the apparatus referred to in the preceding claim, of an
electric circuit including a signalling apparatus so arranged that when the cock is
closed the circuit is closed, and when the cock is opened the circuit is broken, substan-
tially as herein described.
