or other Mechanism.
.
WILLIAM REEVES Watch Manufacturer of 9. Whitehead Road Aston Juxta
Birmingham in the County of Warwick do hereby declare the nature of this Invention
to be as follows :-
Improvements for opening and closing Cocks and Valves Automatically being
attached to Clockwork or other Mechanism and may be applied to Clocks Street
Lamps and Railway Signals or any kind of Gas apparatus where Cocks or Valves
are applied and may be opened or Closed or partially Closed by the said Invention
Automatically at any given time attached to the Cock or Valve is a spring inserted
or otherwise in a similar manner to the spring in the barrell of a Watch or Clock on
one side the Cock or valve and an arm or Lever on the other side or both sides if
required.
The arm or lever being kept back by a cam a section of the cam being cut away'
releases the arm or lever and opens the Cock or Valve and as the cam travels with
the part of Clockwork or Mechanism to which it is affixed the Cock or Valve is
Closed or partly Closed.

Opening and Closing Cocks and Valves Automatically by Clockwork
or other Mechanism.
I, WILLIAM REEVES of 9, Whitehead Road, Aston, Juxta Birmingham in the
County of Warwick Watch Manufacturer do hereby declare the nature of my said
invention and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:
:-
My invention has for its object the opening and closing of cocks and valves
automatically by clockwork or other mechanism by which I am enabled to illuminate
clocks and operate street railway signal or other lamps or any other kind of apparatus
where cocks or valves are applied at any desired fixed interval or any given time
in a simple, easy and effective manner.
In order that my invention may be clearly understood and more easily carried
into practice have appended hereunto a large sized sheet of drawings upon which I
have illustrated my invention applied for the purpose of illuminating an ordinary
portable alarum clock as well as the means of applying same to street lamps Doctors
lamps or other similar requirements.
Figure 1 is a front elevation of an ordinary portable alarum clock with the gas
valve A and burner B attached for the purpose of lighting up the face at any desired
time.
Figure 2 is an enlarged view of the mechanism for operating the valve A showing
it in position with the valve closed.
Figure 3 is a similar view of Figure 2 but shewing the mechanism in position with
the valve open.
Figuro 4 is a section through Figure 2 on line 1. 2.
Figure 5 is a section through Figure 4 on line 3. 4.
Figure 6 is a front elevation of the cam suitable for street lamps shewing the
sections arranged for the arm E to be released and the valve open only one quarter
of the time of revolving.
Figure 7 is a similar elevation but shewing the sections arranged for the arm E to
be released and the valve open three quarters of the time of revolving.
Figure 8 is an end elevation of Figure 6.
The cock or valve A is placed in a convenient position with regard to the
mechanism by which it is operated and is provided with the arm E which is secured to
the plug or revolving portion a' of the valve to which also the end f¹ of the coiled
spring F is fixed the other end f? being secured to the outside casing of the valve A
in such a manner that the normal position of the valve is to remain closed.
The cam H is connected by preference with the hour wheel M so as to revolve
therewith by means of friction and is provided with a section of its circumference
reduced as shewn at, ¹. This section may be of more or less length to suit the time
during which it is required for the valve to remain turned on and in the case of the
automatic lighting of street lamps the cam would be formed as shewn by Figures 6,
7 and 8 which is composed of the separate sections H, H' and H' to allow of the
reduced portion of the cam being lengthened or shortened according to the length of

page_text: the periods which the valve may be required to remain turned on. The cam H in the
case of the clock is secured to the hour wheel M or its equivalent by means of the
disc sufficiently firm to revolve with it by means of the friction but as the hour
wheel is fixed by its gear with the wheel m¹ the cam H can be separately revolved
for adjusting by means of the hand K which is connected to the cam by the small
pin entering the hole in the disc thereby allowing of the friction being overcome.
In the case of the cam to the street lamp or other arrangement of valve as shewn by
Figures 6, 7 and 8 the section H is fixed to the operating wheel and the sections H
and H2 are secured to it sufficiently to revolve with it by friction but H¹ and H' may
be revolved separately by means of two fingers which would be attached in the same
way as in the case of the clock i.e. each by a pin k¹ Figure 4 entering the hole ³ on
each section and by these means the reduced portion can be made of greater or lesser
semi-circumference as may be desired.
The wire arm e¹ is connected to the lever E in such a manner that when the lever E
falls and turns on the valve as shewn at Figure 3 the wire hook e releases the arm s¹
on the hammer arbor S and allows the hammer to strike the alarum N.
In the case of the lighting up of the alarum clock shewn by Figures 1, 2, 3, 4.
and 5 the gas is connected to the pipe P which may be in any desired position and
passes up through the pipe in the direction from pl to p² and on to the burner Ba
slight groove a³ in the plug a¹ or other arrangement being provided to allow a slight
amount of gas to constantly pass, the action of setting for the gas to be turned up at
any particular time being as follows. It will be seen that the reduced portion of
the cam H is in such a position that the lever falls when the finger K is at the
hour twelve so supposing it to be twelve by the clock when being set and that the
gas is required to be turned up at five o'clock the finger K would be set five hours
before twelve i.e. at the hour seven in which position the lever E would be up and
the valve closed and as the finger K travels with the cam H and hour wheel or other
operator M as soon as the finger K reaches the twelve which would be at five
o'clock the lever E drops into the position shewn by Figure 3 thereby turning up the
gas and at the same time liberating the arm s¹ to the hammer of the alarm N as
before described.
.
In the case of the operating of valves for the lighting of street lamps the action of
the falling of the lever is exactly the same as before described but the propelling
wheel which in this case takes the place of the hour wheel preferably revolves once in
twenty-four hours and the sections H, H' and H2 of the cam are made to move with
it but in this case the length of time the lever is allowed to fall and turn on the
valve and the number of hours which the light is left burning is regulated by the
sections H, H and H2 of the cam being more or less open or closed as before
described and shewn by Figures 6, 7 and 8.
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:-
The improved apparatus for turning a light up or down in conjunction with and
by the mechanism of a clock, automatically, substantially as herein set forth and
illustrated upon the accompanying drawings.
