Mechanical Engineer. "IMPROVEMENTS APPLICABLE TO STEAM AND OTHER MOTIVE-
POWER ENGINES."
This Invention relates to an improved construction of governor for regulating
the speed of steam or other motive-power engines. This object is effected by means
of a pendulum arrangement, whereby a uniform speed, or the alteration to any
desired speed; can be obtained in a simple and effective manner.
The Invention is applicable to any engine in which the motive agent is steam or
any other aeriform fluid.
The governor can be constructed either as one arrangement in which the throttle
valve, the stop valve, and the pendulum are combined in one contrivance, and
requiring no further lever, links, chains, or the equivalents for its action and proper
performance, or it can be constructed without the throttle and stop valve, and
made to actuate (for example) the expansion gear or the throttle valve of a
stationary or portable engine.
In the latter arrangement the action of the governor may be increased to a very
great extent and power.
In both cases the levers of the pendulum apparatus are jointed together,
and the several parts are so arranged as to force the balls on the ends of the
principal levers to move in an elliptical curve, whereby a contrivance is obtained

page_text: which allows the speed of rotation necessary for. equilibrium to be very high
indeed without making the pendulum levers unduly small. This arrangement
moreover admits of the adaptation thereto of a spring arrangement, by which an
alteration of the speed of the engine may be obtained to any desired extent merely
by turning an adjusting screw or nut which has been provided for the purpose
at the top of the revolving governor frame, or below it, as the case may be.
One form of our improved governor consists of a frame which carries two bevil
wheels, to one of which is fastened a hollow vertical spindle. This frame is
enlarged at its upper part, so as to act as a support for the fulcrums of the pendulum
levers. Through this hollow spindle is passed a solid spindle of smaller diameter.
The hollow spindle and its enlargements is securely held in place by the governor
frame, but is allowed to rotate only, whereas the smaller spindle, which passes
through the centre of the hollow spindle, has not only a rotary motion (coinciding
with that of the hollow spindle), but also an axial motion or a longitudinal-motion in
the line of its axis..
The central spindle carries on its upper end a cross piece, to which are jointed
the pendulum levers in such a way that with the aid of two small links (the upper
ends of which are jointed to the head of the hollow vertical spindle above mentioned,
and the other ends to the ends of the pendulum levers respectively) the centres of
the balls are made to describe an elliptical curve. Thus when the balls rise, the
central spindle is lifted, and with it the throttle valve, which is connected thereto by
means of a coupling, which allows of axial motion, or a rising and falling motion only
boing communicated to the valve.
The top part of the enlargement of the hollow vertical spindle (which carries the
bevel wheel) has a provision for receiving a peculiarly shaped nut, with a deep
recoss for holding a spring made of steel or brass, and which acts upon the cross piece
of the central spindle previously mentioned. Thus the downward pressure resulting
from the spring can be adjusted to any desired degree, and consequently the rising
of the balls can thus be modified to meet the requirements of various speeds..
In order to counteract the little pressure in excess upon the equilibrium valve,
resulting from the area of the central spindle to which the valve is fastened, the
latter lins on its lower end a sort of hollow cone, against which the fluid passing
through the throttle valve will strike before passing into the steam chamber, thus
causing a downward pressure to act upon it. This pressure, can be properly
adjusted by suitably choosing the size of the cone, which will then balance the excess
of the pressure of the equilibrium valve, which results from the small area of the
central spindle which carries the throttle valve.
In cases when it is found more convenient that the throttle valve should be
separated from the governor and its stand, a coupling is used which transmits
the axial motion of the central shaft by means of a simple lever arrangement to the
throttle valve. This coupling is placed just above the bovil wheels on the lower
end of the hollow spindle; such an arrangement will be found applicable for-portable
engines;
in this case the spring is adapted to the lower end of the inner central
spindle, and can be easily adjusted upon it by means of a nut and washer.

ங் IMPROVEMENTS APPLICABLE TO STEAM AND OTHER MOTIVE:
POWER ENGINES."
This Invention relates to an improved construction of governor for regulating
the speed of steam or other motive-power engines. This object is effected by means
of a pendulum arrangement, whereby a uniform speed, or the alteration to any
desired speed, can be obtained in a simple aud effective manner.
The Invention is applicable to any engine in which the motive agent is steam or
any other aeriform fluid.
The governo i can be constructed either as oue arrangement; in which the throttle
valve, the stop valve, and the pendulum are combined in one contrivance; and
requiring no further levers, links, chains, or other equivalents for its action and
proper performance, or it can be constructed without the throttle and stop valve,
and made to actuate, for example, the expansion gear or the throttle valve of a
stationary or portable engine.
In the accompanying Drawing,
Fig. 1 is a sectional elevation of a governor or regulating apparatus constructed
according to our Invention, and adapted for regulating the speed of a steam
engine.
Fig. 2 is a vertical section of the pendulum apparatus and its driving gear.
Fig. 3 is a sectional elevation of an arrangement specially adapted for portable
engines; Fig. 4 is a sectional plan view of the same.
In the latter arrangement the speed of the governor may be modified to a very
great extent by means of a spring; as will be hereafter explained.
In both cases the levers of the pendulum apparatus are jointed together; and the
several parts are so arranged as to force the balls on the ends of the principal levers
to move in an elliptical curve, whereby a contrivance is obtained which allows thé
speed of rotation (necessary for equilibrium) to be very high indeed without
making the penduluin levers unduly small. This arrangement moveover admits of
the adaptation thereto of a spring arrangement, by which an alteration of the speed
of the engine may be obtained to any desired extent merely by turning an adjusting
screw or nut which has been provided for the purpose at the top of the revolving
governor frame, or below it, as the case may be.
One form of our improved governor, as shewn at Figures 1 and 2, consists of n
frame a, a, which carries two bevil wheels b, b', to one of which is fastened a hollow.
vertical spindle c, which is enlarged at its upper part at c*. Through this hollow
spindle c is passed a solid spindle e of smaller diameter.
The hollow spindle c and its enlargement c* is securely held in place by the
governor frame a, a, but is allowed to rotate only, whereas the smaller spindle
6, which passes through the centre of the hollow spindle has not only a rotary
motion (coinciding with that of the hollow spindle), but has also a longitudinal
motion in the line of its axis.
The central spindle e carries on its upper end a cross piece e¹, to which are jointed
the pendulum levers d, d, in such a way that with the aid of two small links d', d, (the
upper ends of which are jointed to the enlarged head e* of the hollow vertical spindles
above mentioned, and the other ends to the end of the pendulum levers respectively)
the centres of the balls at the lower end of the pendulum levers d; d, are inade to

page_text: •
describe an elliptical curve, as indicated by dots in Fig. 2, but their plane of rotation
will always be below the point of support of the hollow spindle. It will be evident
that when the balls rise, the central spindle e is lifted, and with it the throttle
valve f, Fig. 1, the stem of which is connected thereto by means of a coupling g,
which allows of axial motion or a rising and falling motion only being com-
municated to the valve.
The top part of the enlargement c* of the hollow vertical spindle, which carries
the bevil wheel b, has a provision for receiving a peculiarly shaped nut h, made with
a deep recess for holding a spring i, made of steel or brass, and which acts upon the
cross piece e¹ of the central spindle previously mentioned. Thus the downward
pressure resulting from the spring i can be adjusted to any desired degree by simply
turning the nut h, and consequently the rising of the balls can thus be influenced to
meet the requirements of various speeds.
In order to counteract the little pressure in excess upon the equilibrium valve,
resulting from the area of the central spindle e to which the valve fis fastened, -the-
latter has on its lower end a sort of hollow cone j, against which the fluid passing
through the throttle valve will strike, as indicated by the arrows in Fig. 1, before
passing into the stean chamber, thus causing a downward pressure to act upon
the cone, and consequently on the valve. This pressure can be properly adjusted
by suitably choosing the size of the cone j, which will then balance the excess of the
pressure on the equilibrium valve, which results from the small area of the central
spindle which carries the throttle valve f.
The casing f¹, Fig. 2, which carries the throttle valve ƒ, serves to carry a stop
valve arrangement.
The stem of the stop valve is tapped, and receives the screwed end of the
spindle, which passes through a stuffing box, and is provided externally with a
hand wheel, whereby the stop valve can be raised or lowered as may be required.
Steam is admitted through a suitable opening in the box enclosing the stop valve,
and passes from thence through the aperture f* into the cavity containing the
throttle valve.
In cases when it is found more convenient that the throttle valve should be
separated from the governor and its stand, an arrangement is used, such as that
shown at Figures 3 and 4.
The construction and arrangement of the pendulum, levers, and their accessories,
and also the solid central spindle, are similar to those described in reference to
Figures 1 and 2, except that the coupling g is slightly different in form; and the
spring i, instead of being at the top of the solid spindle, as in Figures 1 and 2, is
now at the lower end of the spindle. It will be seen that the bevil wheels are
dispensed with, and a pulley b, Fig. 3, is adapted to the hollow spindle c for the
purpose of driving the same.
The axial motion of the solid central shaft e is transmitted by means of the levers
m, m, mounted on the shaft n, which carries another lever o, which by means of the
rod p and the short lever q on the throttle valve shaft 7 actuates the throttle valve.
One of the advantages of this construction of regulator or governor is that it is
very steady in consequence of the plane of revolution of the balls being always
below the point of support of the hollow shaft.
Having now described our Invention of "Improvements Applicable to Steam and
other Motive-power Engines," and having explained the manner of carrying the
-same-into-effect-we-claim-as-the-Invention secured to us by Letters Patent_as.
-aforesaid;
The general arrangement and construction of parts, herein set forth, for acting
directly upon the throttle valve of steam engines.
We claim particularly the combination of the pendulum levers with the valve
spindle, and also the adaptation thereto of the nut and spring i, whereby the
speed of the engine may be regulated as set forth.
We also claim the arrangement and construction of parts, shewn at Figures 3, and

page_text: ,
4, for acting on the throttle valve of portable engines, traction engines, or engines
of that class.
In witness whereof, we, the said Philip Gibbons, Henry Philip Gibbons, and
Heinrich Adolph Hülsenberg, have hereunto set our hands and seals, this
Twenty-eighth day of November, in the year of our Lord One thousand
eight hundred and seventy-seven.
