PROVISIONAL SPECIFICATION.
A Gas Engine Governor Gear.
CECIL MCKENZIE DOWIE and CHARLES BAIRD HANDYSIDE of 418 Oldham
Road Newton Heath Manchester Engineers do hereby declare the nature of this
invention to be as follows:-
A shaft or ro reciprocated by an eccentric or other suitable gear working
exhaust valve, on it-a sliding weight on same shaft a collar fixed with a screw, the
weight being connected to said collar by a spring. On exhaust valve spindle a
slieve is fixed with a collar on it free to slide on shaft on exhaust valve case a
balanced hook is fixed so that when weight strikes hook it engages with collar on
valve spindle slieve & keeps exhaust valve open working as follows: When engine
exceeds the required speed sliding weight comes in contact with the hook engaging
same with collar & holding exhaust valve open thus preventing engine sucking a
fresh charge of gas.

COMPLETE SPECIFICATION.
A Gas Engine Governor Gear.
CECIL MCKENZIE DOWIE and CHARLES BAIRD HANDYSIDE of 418 Oldham
Road Newton Heath Manchester Engineers 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 :-
A shaft or rod H reciprocated by an eccentric or suitable gearing G for working
exhaust valve together with the spindle marked F on H a sliding weight C
connected to a collar D by a spring E collar D being fixed on H by a screw K
on exhaust valve spindle F a slieve B is fixed having a collar on it slieve B being
free to slide on shaft H on exhaust valve case M is fixed a balanced hook A so
that when weight C strikes hook A it engages with collar on slieve B which
compresses spring I and thus keeps exhaust valve F open.
When the engine is running the weight C slides up and down on the rod H by
the reciprocating motion of the rod Hits travel being limited by the tension of
the spring E. Upon the engine exceeding the required speed the weight Cover-
comes the tension of spring E and drives the hook A down over the collar B the
valve F being thereby opened owing to the forward movement of the rod H thus
holding the valve F open so long as weight C. keeps hook A down. The space
behind the piston being open to the atmosphere a fresh charge of gas cannot be
drawn into the cylinder. Upon the engine again attaining its proper running
speed the weight is unable to reach the hook A not having sufficient momentum to
overcome spring E the hook A is therefore released and is free to return to its
original position allowing the valve F to close by the spring I being freed. The
engine then draws a fresh charge of air and gas.
The speed of the engine can be varied by altering position of collar D
on Hod H

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is
1. The use of a balanced hook A working into the slieve B hereinbefore
particularly described.
2. The use of the sliding weight C on the shaft or rod H as a means of regulating
the working of the balanced hook A.
3. The combination of the shaft or rod H the sliding weight C and the balanced
hook A working into the slieve B for the purpose of governing the engine.
