COMPLETE SPECIFICATION
Automatic Governor Regulator.
1, HERBERT JAMES PAGE of the Town of St. Mary's, in the County of Perth,
in the Province of Ontario, Canada, Stationary 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 :-
This invention relates to a certain new and useful speed" regulator for the
governors of steam engines, water wheels and the like, and' has for its object to
provide a device whereby said governors may be automatically regulated to run at
a uniform rate of speed under varying loads and steam pressures.
I
And this invention consists of a segmental plate or bar arranged above its
pivotal support, which plate or bar is instantly and automatically adjusted by the
governor to move more or less to either side of its pivotal support, to increase or
decrease its resistance to the governor, and also of the combination with the above
of means for connecting said plate or bar with the governor spindle, and to adapt
it to set or regulate the speed, or for the purpose of adapting a single device to
regulate governors of different speeds.
In order that my improvements may be better understood I have illustrated
in the accompanying drawing an automatic speed regulator constructed according
to my invention.
In which drawings,
Fig. 1. is a side elevation of a governor and an automatic speed regulator
embodying my invention.
Fig. 2. shows the application of same to another form of engine and governor.
In these drawings,
S, designates à suitable support for the governor.
H, the governor spindle; and I, I, the governor balls.
A, designates a lever pivotally supported on the stud; a, 'the latter being secured
to the support, S.
The arm, b, of said lever, A, is pivotally connected with the governor
spindle, H.
C, designates a chain or other flexible or yielding connection which extends
from, and connects the arm, d, of said lever, A, with the segmental bar or
plate, D.
D, designates a segmental bar or plate which may be in the form of any
segmental part of a circle or other geometric figure and pivotally supported
on the pivot, e, the latter being held in place and supported by an arm or
support, E.
In Fig. 1. the governor spindle, H, is connected with the valve gear (not shown)
and in Fig. 2. the lever, A, is connected by the connecting rod; B, with the valve
gear (not shown).
The operation is as follows ;-
When the load is increased or the steam pressure reduced the governor balls
will take the lower position designated by dotted line, F, and with the attachment
of this segmental bar or plate, D, in the form shown, the resistance to the
centrifugal force of the governor balls is increased or becomes greater, because the
segment, D, is adjusted to the position shown by dotted line, G, or a greater
portion thereof will be adjusted to the side of its pivotal support opposite to, ve

against the governor, consequently this greater portion will act as an
resistance to the centrifugal force of said governor balls.
increased
And if the load should be reduced, or the steam pressure increased, the governor
balls would take the higher position desiguated by dotted line, K; and with the
attachment of this weight, D, the resistance to the centrifugal force of the governor
balls is reduced or becomes less, because the segmental bar, D, is adjusted to the
position shown by dotted line, L, or a greater portion thereof will be adjusted to
the same side of its pivotal support as the governor, consequently this will reduce
the resistance of the segmental bar or plate, D, to the centrifugal force of said
governor balls, because the portion of the weight on the same side of its pivotal
support as the governor will counteract an equal weight on the side of the
segmental plate opposite to the governor.
As a result this weight operating as described offers less, resistance to the
governor as the latter tries to lift it, so that as the governor experiences greater
difficulty in raising the balls to a higher plane, the weight to be lifted becomes
lighter, and this segmental bar or plate offers greater resistance to the governor
on its reverse action, thus securing a more constant action of the governor, and,
consequently a more regular speed of the engine.
du, order to regulate: different, speeds with the one device, additional seginental
plates or bars may be, secured to the oue in use, or pivotally supported on the
pivot, e or said segmental plate or bar, D, may be adjusted more or less to either
side of its, pivotal support; when setting the speed by adjusting the segmental bar
or plate, D, towards the dotted liue, G, this plate or bar acts as a resistance or is
set against, or regulates a governor of a higher speed, the reverse result, would
be accomplished by setting said segmental bar or plate in the direction of the
dotted line, L.
The constructions berein shown and described, I have found by experiment to
give the best results, but the segmental bar or plate may be formed of a straight
or curved bar, plate or tube, and with or without an enlarged weighted rim,
(without an enlarged weighted rim by constructing this device of a segmental
plate, and distributing the weight equally over said plate) or this segmental bar
may be in the form of a circle or wheel, the rim of which is weighted unequally,
or this segmental plate or bar may be connected with the trip shuft of another
form of engine, or be connected with a counter shaft, and an arm from this shaft
or from the segmental bar or plate, engaging with the governor spindle, so that
while I prefer the construction shown, I do not limit myself to the details thereof, as
they may be modified in various ways, without departing from the spirit of my
invention.
Having now particularly described and ascertained the nature of my said inven-
'tion, and in what manner the same to be performed; I declare that what I
