IMPROVEMENTS IN REGULATORS FOR GAS ENGINES
Year: 1885

page_text: We FREDRICK LEIGH CATTRALL 25 Victoria Street Liverpool Merchant and
CHARLES STOUT of 12 Westmorland Street in the City of Liverpool Engineer do
hereby declare the nature of our Invention for IMPROVEMENTS IN REGULATORS FOR
GAS ENGINES to be as follows:-
:-
The object of this invention is to reduce the consumption of gas used in gas
engines when the load is removed, applicable more particularly when such engines
are used for hoisting or where the load is intermittent and not constant. The
general arrangment of governors of gas engines is the ordinary type having
the arms resting on the spindle and a loose bush with the addition of a portable
weight or spring placed on the top to increase the speed of such engines. Now it
is manifest that this weight increases the power by causing the engine to make
more revolutions in a given time the explosive force of the gas being almost
constant provided the load is constant notwithstanding the number of revolutions
the engine makes per minute, therefore it is evident that if the weight on the
governor is removed the number of revolutions is immediately reduced and
consequently the consumption of gas in ratio to the relative ratio of weight used.
Now to actuate the weight and the manner of so doing is the subject matter
which I now propose to explain. Upon a standard secured to engine or otherwise
secured I fit a lever to one end of this lever the weight is secured so that when
the lever is moved the weight is moved in a vertical direction, on the other end of
said lever I connect a balance weight or spring with regulating screw the power of
such weight or spring being equal to overcome the weight on governor so that if
the lever is not otherwise influenced the spring is sufficient to lift the weight
off governor, opposite this spring and capable of actuating the lever in an opposite
direction I attach a rod, chain, or cord fitted with spring and regulating screw
this rod is carried to the hoist or machine which the engine works and so arranged
that when the hoist or machine is put into gear the rod is tightened and the
weight let down on to the governors thus increasing the power, and the reverse
action takes place when the machine is put out of gear. Where there is only
one machine driven by the engine I dispense with the lever, and connect the
rod directly on to the weight and arrange it so that when the machine is put
into gear the weight is lowered and the reverse when the machine is thrown
out of gear,

FREDRICK LEIGH CATTRALL Merchant 44 Victoria Street and CHARLES STOUT
Engineer 12 Westmoreland Street both in the City of Liverpool County of
Lancaster do hereby declare the nature of our invention for IMPROVEMENTS IN
GAS ENGINE REGULATORS 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 this invention is to reduce the consumption of gas used in gas
engines when the load is removed, applicable more particularly when such engines
are used for hoisting, or where the load is intermittent and not constant The
general arrangment of gas engines is the ordinary type of governor having the
arms resting on the spindle and a loose bush with the addition of portable weight
or spring resting or pressing on the top to increase the speed of such engines.
Now it is manifest that this weight increases the power by causing the engine
to make more revolutions in a given time, the explosive force of the gas being
almost constant provided the load is constant notwithstanding the number of
revolutions the engine makes per minute, therefore it is evident that if the weight
on the governors be removed the number of revolutions is immediately reduced
hence the consumption of gas in ratio to the relative ratio of weight used on
governors.
To actuate this weight and the manner of so doing is fully explained as follows.
Upon a standard 1. secured to engine or otherwise secured I fit a lever 2, to
one end of which the weight 3 is secured but free to revolve, so that when the
lever 2. is moved the weight 3 is moved in a verticle direction, on the other end of
said lever 2 I connect a balance weight or spring 4 with regulating screw 5, the
power of such weight or spring 4 being sufficient to overcome the weight 3 on
governor 6, opposite the spring 4 and capable of actuating the lever 2 in an
opposite direction I attach a spring similar to 4 (spiral springs are preferable) to
the other end of said spring I attach a rod, wire, cord, chain, or other means
of communication 7 with or without a regulating screw, and arranged so that
any number of hoists or machines may be connected to the said means of
communication 7 in the following manner.
Upon the striking gear of hoist or machine a rod, wire, cord, or chain &c, is
secured and conveyed over pulleys or otherwise to the means of communication 7,
so that when the hoist or machine shall be put in motion the cord &, is pulled
and the lever 2. is lifted causing the weight 3. to be let down on to the governor,
by this means increasing the speed and power of engine; any single hoist of a
series being put in motion actuating the weight 3, on governor.
Or instead of useing a lever 2 as described a spring or its equivalent fixed
immediately above the weight 3, or so arranged with and connected to said
weight 3 that when said spring or its equivalent, is not otherwise influenced will
have sufficient power to lift weight 3 off the governors,
Now if the means
of communication 7. be arranged to influence said spring or its equivalent in
such a manner that when the hoist or machine is put in motion the spring &e
is liberated and the weight 3 let down on governor with the effect as above
described

page_text: Or where only one hoist or machine is used the weight may be attached to the
starting gear of hoist &c direct so that when hoist &c is not in motion the weight 3
is lifted off the governor, and when put in motion the weight 3 is let down on the
governor with the effect as described.
I now claim as being novel
First. The combination of lever 2, weight or spring 4, for actuating weight 3, in
connection with the means of actuating said lever 2 by or from the starting gear
or otherwise, directly or indirectly of hoist or machine to which it is applied as
described.
Second. The combination of spring or its equivalent for lifting weight 3 off
governor in connection with and actuated directly or indirectly by the starting
gear of hoist to which it is applied as described.
Third. The combination of means of communication 7, and weight 3 actuated
directly or indirectly by the starting gear of hoist or machine or otherwise
actuated.
