Improvements in Speed Regulating Governors for Steam Engines and
other Prime Movers.
I, HARRY CHARLES GEARING, of Penshurst, Clarence Drive, Harrogate, in the
County of York, Engineer, do hereby declare the nature of this invention to
be as follows:-
In accordance with this invention a rod or bar-lever carrying adjustable governor-
balls is fulcrumed to a vertical rotating spindle driven by any suitable means.
One arm of the said rod or bar-lever is connected say by means of a link to
any suitable weight or constant load arranged in such wise that the said rod or
bar-lever will assume a more or less angular position in its relation to the
horizontal plane accordingly as its centrifugal velocity is diminished or increased.
The general arrangement is such that as the centrifugal velocity of the said
rod or bar-lever is increased the constant load will be overcome by aid of centri-
fugal force and the said rod or bar-lever will move or lift towards an horizontal
position thereby operating the governor-valve of the steam engine or other prime
mover the connecting mechanism with which may be of any known or suitable
construction. As the centrifugal velocity of the said rod or bar-lever is diminished
thereby incurring a loss of centrifugal force the constant load will drop thus
causing the said rod or bar-lever to fall to an angular position and in turn
operate the governor-valve of the steam engine or other prime mover.

Improvements in Speed Regulating Governors for Steam Engines and
other Prime Movers.
I, HARRY CHARLES GEARING, of Penshurst, Clarence Drive, Harrogate, in the
County of York, 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:-
In accordance with this invention a rod or bar-lever, carrying governor-balls
preferably rendered adjustable, is fulcrumed to a vertical rotating spindle driven
by any suitable means. One arm of the said rod or bar-lever is connected, say

page_text: by means of a link, to any suitable weight or constant load or resistance arranged
in such wise that the said rod or bar-lever will assume a more or less angular
position in its relation to the horizontal plane accordingly as its centrifugal
velocity is diminished or increased.
Referring to the accompanying illustrative sheets of drawings in which like
reference-letters indicate like parts in all the figures. Fig. 1 Sheet 1 shews in
sectional elevation a speed regulating governor made substantially in accordance
with this my said invention, whilst Fig. 1 Sheet 2 is a part-sectional elevation,
and Fig.
Sheet 2 an end elevation of a governor illustrating certain modifica-
tions of carrying my invention into effect.
In Fig. 1 Sheet 1 the governor-rod or bar-lever A, having balls B, b, rendered
adjustable in any convenient manner, is fulcrumed at C to a screw-pin c screwed
in a vertical spindle D having a forked end d. As is usual the mechanism
for rotating the vertical spindle D works within the standard F. The governor-
rod A. is attached by means of a link or bar G to revolving weights H, h; the
rotary motion of the top weight H being transmitted to a non-rotary lifting or
governing motion at h. It will be understood that any convenient mechanism
may be employed to transmit the governing motion from the weight h to the
engine or other prime mover.
In Figs. 1 and 2 Sheet 2, the revolving weights H, h, are dispensed with and
the constant load or resistance employed is in the form of a spring I seated upon
a screw-piece J in such wise that the compression upon the spring I may be varied
to meet different requirements. The upper end of the spring I abuts against
a flange K formed on the spindle D carrying the governor-rod A and balls 1, b.
In this instance the governor-balls B, 6 are shewn made in one with the governor-
rod A, and although this may be desirable in some cases I generally prefer to
have the governor-balls adjustable, as shewn in Fig. 1 Sheet 1, in order to
facilitate the balancing of the governor. The sliding piece M, to which the screw-
piece is secured, is connected to the governor-rod A. by means of the link G.
The spring I and sliding piece M revolve and are carried round with the spindle D
by means of a raised key N. In this example the governing motion is taken
from the loose ring 0, carried by the screw-piece J, by any convenient means.
The general arrangement is such that as the centrifugal velocity of the governor-
rod A and balls B, is increased the constant load or resistance (see H, hin
Fig. 1 Sheet 1, and I in Figs. 1 and 2 Sheet 2) will be overcome by aid of
centrifugal force, and the said governor-rod and balls will move or lift towards a
horizontal position, (see dotted lines in Fig. 1 Sheet 1), and in turn operate the
governor valve of the steam engine or other prime mover. As the centrifugal
velocity of the said governor-rod and balls is diminished, thereby incurring a
loss of centrifugal force, the constant load or resistance will overcome to some
extent the centrifugal force, thus causing the governor-rod and balls B, b
to fall to an angular position, (as shewn in full lines in all the Figures), and
duly operate the governor valve of the steam engine or other prime mover.
It will be understood that various other forms of apparatus, differing consider-
ally in detail, for governing steam engines and other prime movers may be
devised without departing from the nature of this my said invention.
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
1. In speed regulating governors for steam engines and other prime movers
a rod or bar-lever carrying balls preferably rendered adjustable fulcrumed to a
revolving spindle and connected say by means of a link or bar to any convenient
form of constant load or resistance in such wise that as the centrifugal velocity
of the said rod or bar-lever and balls varies the governing mechanism of the steam
engine or other prime mover will be in turn regulated.
