PROVISIONAL SPECIFICATION
Improvements in Mechanism for Governing the Speed of Gas and .
similar Motor Engines.
.:
I HUGH WILLIAMS of The Mount, Stockport, in the County of Chester, Engineer,
do hereby declare the nature of this Invention to be as follows:-
My invention relates to improvements in that arrangement of mechanism for
regulating the supply of gas or other fluid to gas and similar motor engines in
which the admission valve is opened by a finger or trigger connected to the governor
and pivoted on a vibrating lever operated from an eccentric or cam or equivalent
on the crankshaft.
In such an arrangement when the engine has exceeded its normal speed. the
governor acts to withdraw the finger so as to leave the admission valve, closed and
thereby allow no gas or other fluid to be admitted to the engine but when the engine
resumes its normal speed the governor moves the finger back into position to again
actuate the admission valve.
Now according to my present improvements I employ in connection with the
pivoted finger a weight supported by an adjustable spring or springs which weight
when the engine is running at or below its normal speed is held in equilibrium by
said spring or springs and so vibrates with the lever upon which the pivoted finger is
mounted without however operating said finger to withdraw it from under the
admission valve; but when the speed of the engine rises the consequent acceleration
in the movements of the vibrating lever and the inertia of the weight cause the spring
or springs to yield more or less whereby the weight acting on the pivoted finger
moves it out of the way of the striking plate on the admission valve. The effect of
this movement of the finger is that no gas or other fluid is admitted to the engine
until the necessary reduction in its speed has been effected.

Improvements in Mechanism for Governing the Speed of Gas and
similar Motor Engines.
I, HUGH WILLIAMS, of The Mount, Stockport, in the County of Chester, Engineer,
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:-
My invention relates to improvements in that arrangement of mechanism for
regulating the supply of gas or other fluid to gas and similar motor engines in which
the admission valve is opened by a finger or trigger connected to the governor and
pivoted on a vibrating lever operated from an eccentric or cam or equivalent on the
crankshaft.
In such an arrangement when the engine has exceeded its normal speed the
governor acts to withdraw the finger so as to leave the admission valve closed and
thereby allow no gas or other fluid to be admitted to the engine but when the engine
resumes its normal speed the governor moves the finger back into position to again
actuate the admission valve.
Now according to my present improvements I employ in connection with the
pivoted finger a weight supported by an adjustable spring or springs which weight
when the engine is running at or below its normal speed is held in equilibrium by

page_text: said spring or springs and so vibrates with the lever upon which the pivoted finger is
mounted without however operating said finger to withdraw it from under the
admission valve; but when. the speed of the engine rises the consequent acceleration
in the movements of the vibrating lever and.the inertia. of the weight.cause, the spring
or springs to yield more or less whereby the weight acting on the pivoted finger
moves it out of the way of the striking plate on the admission valve. The effect of
this movementrof the fingers is that: norgas or other fluidnis admitted tontlenengino
until the necessary reduction in its speed has been.effected.
And in order that my Invention, may. be.fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings.reference being had to.the
figures and letters marked thereon..
Figure 1 is a side..elevation partly in section of iny improved mechanism for
governing the speed of gas and other similar motor engines and Figure 2 is an
end elevation of the same.

In these views. a designates the vibrating lever which is fulcrumed at band is
rocked by the rod e actuated by the eccentric & on the crankshaft e fis the striking
plate on the admission valve which plate may either be plain as shown or may be
notched or serrated: g' is the finger or trigger mounted on the elbow lever
end of which.rests in a groove h¹ in the weight the lever g being pivoted on tho
vibrating lever a: h is the weight which is supported by the spring i the latter
being coiled around a spindle; which is screwed into an arm. k secured to the
vibrating lever a. The spindle j passes through the weight which is secured thereto
by a pin and on a screwed portion of the spindle jare two nuts by means of which
the tension on the spring i may be regulated as desired.
.
Havingunowa 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 1:1
claim is :
1. The combination with the finger which is pivoted: on a vibrating, lever.. and.
arranged to operate the admission valve of a gas or similar motor engine, of..a .weight
supported by an adjustable spring or springs mounted on the vibrating lever. and.
arranged to act upon said finger substantially in the manner and. for the purposes
herein described with reference to the accompanying Drawings.
2. The combination and arrangement of parts embodying my improvements in
mechanism för governing the speed of gas and similar motor engines substantially as
herein set forth.
