hereby declare the nature of this Invention to be as follows:-
The object of my Invention is to provide a compact cheap and efficient governor
wherein the ordinary hinged joints are dispensed with and a very small movement is
required to give the desired effect. The governor is also very readily and delicately
adjustable to the speed required.
According to my Invention I fix upon a shaft rotated from a moving part of the
machine to be governed springs or flexible carriers upon which are mounted weights
capable of being slidden and fixed in any desired position thereon. The springs or
flexible carriers are connected by springs or otherwise to a lever fixed to a part which
is longitudinally movable in or with respect to the shaft and the balls and other parts
carried by it so that as the balls and consequently the springs or flexible carriers move
outwards under centrifugal force the said longitudinally moveable part operates upon
the throttle valve or other place whereby or whereat the speed is to be controlled.
The said shaft and springs or carriers and the parts carried thereby are capable of a
movement of partial rotation with respect to the longitudinally moveable part con-
nected to the throttle valve and the said shaft or an attachment thereof carries inclined
planes which act upon other inclined planes on or carried by the longitudinally moveable
part so that when the machine is in motion as the balls Hy apart the flexible carriers
or springs on which they are mounted move outwards and cause the connections
thereof with the lever on the longitudinally moveable part to give the aforesaid partial
rotatory movement to cause the inclined planes to ride over each other and so move
the longitudinally moveable part lengthwise to act upon the throttle valve or other
part by or at which the motion of the machine is regulated.
I prefer for compactness to make the longitudinally moveable part pass through the
centre of the shaft of the governor.

I, ALFRED SHAW, of St. Ann's, Lewes, in the County of Sussex, 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:-
The object of my invention is to provide a compact cheap and efficient governor
wherein the ordinary hinged joints are dispensed with and a very small movement is
required to give the desired effect. The governor is also very readily and delicately
adjustable to the speed required.
According to my Invention I fix upon a shaft rotated from a moving part of the
machine to be governed springs or flexible carriers upon which are mounted weights
capable of being slidden and fixed in any desired position thereon. The springs or
flexible carriers are connected by spring links or otherwise to a lever fixed to a part
which is longitudinally moveable in or with respect to the shaft and the balls and
other parts carried by it so that as the balls and consequently the springs or flexible
carriers move outwards under centrifugal force the said longitudinal moveable part
operates upon the throttle valve or other place whereby or whereat the speed is to be
controlled. The said shaft and springs or carriers and the parts carried thereby are
capable of a movement of partial rotation with respect to the longitudinally moveable
part connected to the throttle valve and the said shaft or an attachment thereof carries
inclined planes which act upon other inclined planes on or carried by the longi-
tudinally moveable part so that when the machine is in motion as the balls fly apart
the flexible carriers or springs on which they are mounted move outwards and cause
the connections thereof with the lever on the longitudinally moveable part to give the
aforesaid partial rotatory movement to cause the inclined planes to ride over each
other and so moves the longitudinally moveable part lengthwise to act upon the
throttle valve or other part by or at which the motion of the machine is regulated.
I prefer for compactness to make the longitudinally moveable part pass through
the centre of the shaft of the governor-The accompanying drawing represents a
governor constructed according to my Invention Figure 1 being a longitudinal
section Figure 2 an end view and Figure 3 a detail hereinafter described-A is a
hollow shaft or spindle mounted on a bearing in the bracket B fixed to any suitable
part of the machine or adjacent place. C is a pulley keyed or pinned by a key or
pin c to the spindle A. Over this pulley passes a band which derives its motion from
any suitable part of the machine to be governed-On the opposite end of the spindle A
are formed or fixed arms D D to each of which is bolted by bolts e the inner end of
one of the two springs E E the outer end of each of which springs is rivetted by a
rivet to a boss e to which are secured (by the screws) the outer ends of the
links F the inner ends of which links are secured by the screws f' to
the lever G

page_text: fixed firmly to the end of the rod I which passes through the centre of the spindle A
and forms the means by which the governing influence is communicated For example
it may lead to and actuate the throttle valve-The lever G has at back inclines
which bear against similar inclines on the boss D' which forms the means of fixing
the arm D D to the spindle A-The links F are shewn as being made springy to keep
the rod I in and return it to its normal position but a special spring can of course be
used for the purpose if desired. K are the governor balls one fixed to each of the
springs E E These balls may be made in halves with grooves into which the springs
take the halves when they have been placed in position being secured by the bolts
and nuts kk-These form the means also for adjusting and fixing the balls at any
desired position on the springs-In operation the spindle A is rotated from the
machine whose motion is to be governed or the like and as the balls move apart under
centrifugal action they move the free ends of the springs outwards also, and through
the links F the lever & has a motion of partial rotation given to it and the inclines g
bear on and nove over the inclines so that the rod I is moved longitudinally to
convey the necessary motion to the throttle valve or the like Figure 3 shews the
inclines and on the boss D2 and lever G more clearly.
The governor may be situated and work in a horizontal vertical or any required
position.
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
First In governors for motive power engines or for analogous purposes the
combination of balls or weights with springs which as the balls or weights move
under the influence of centrifugal force are deflected and operate upon the throttle
valve or other equivalent device substantially as hereinbefore described.
Second The governor for motive power engines or the like constructed or
arranged substantially as hereinbefore described and illustrated by the accompanying
drawings.
