SPECIFICATION.
An Improved Governor.
I, OKEY KENNETH COLE, of Parkersburg, in the County of Wood, and State of
West Virginia, United States of America, Inventor, 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 an improvement in governors.
The object is to provide a governor which shall be very sensitive, in which the
movement shall be steady, the wearing friction reduced to a minimum, and which shall
be simple and durable.
With these ends in view my invention consists in certain features of construction
and combination of parts, as will be hereinafter described and pointed out in the
claims.
In the accompanying drawings, Figure 1 is a vertical sectional view showing the
parts assembled with valve full open, the dotted lines showing the position of the valve
full closed. Figure 2 is a partial view in side elevation showing the speed-regulating
device, a portion of the support being broken away. Figure 3 is a detail view
of the inner valve-section, and Figure 4 is a detail view of the outer valve-
section.
A represents the shell of the valve-chamber, here shown of globular form and
provided at one side with an opening a for the admission of steam from the boiler, and
with a central opening extending therethrough and furnishing at its lower end an
opening a¹ for the exit of the steam to the cylinder, the upper greater portion of said
central opening forming a guide and seat for the reception of the outer valve-section.
The snell A is further provided with an interior annular recess a², in communication
with the steam-inlet opening a, and with a steam-port a³, connecting the upper portion
of the central through-opening with the lower portion of said opening.
The outer valve-section B is of general cylindrical form, open at its lower end and
closed, or partially so, at its upper end for the attachment of its hollow stem b. The
valve-section B is provided with a port 6, open to the steam-inlet a, and with ports ²,
open to the upper portion of the said central through-opening, and the portion a¹ of
said through-opening, which surrounds the portion of the valve-section B where the
ports are located, is larger than the section B, forming a steam-chamber surrounding
the said section. The steam is also free to pass around the section B through the
annular recess a². The section B is thus effectually balanced.
disc
Within the hollow section B the inner valve-section C is located. It consists, pre-
ferably, of an upper and a lower disc portion e¹ and c², connected by a central shank c³,
the lower disc portion being provided with depending guides . The upper
portion c¹ is constructed to engage an annular seat 63, just below the ports 3, at the
same time that the lower disc portion c² engages an annular seat 6, and when the
disc portions are so engaged the steam is entirely cut off. When disengaged from
its seat the steam is free to pass from the inlet a beneath the lower disc to the outlet a',
and also beneath the upper disc through the ports 6, and thence through the port
to the outlet a. The valve-section C is also effectually balanced. The stem c,
operating the section C, extends up within the tubular stem 6 of the section B
for

page_text: The support D for the valve-actuating mechanism is secured to the top of the
shell A and has a bearing d at its side, in which the governor-driving shaft E
is journaled, and with a bearing d¹, in which the rotary ball-support Fis
journalled.
The drive-shaft E has fixed thereon a bevel gear-wheel e, which meshes with a
corresponding bevel gear-wheel f, fixed on the sleeve f¹, which depends from the rotary
ball-support F.
The balls G are supported from below by angle-levers 9 pivotally secured to
diametrically-opposite lugs f2 on the support F, the balls being secured to the
upwardly-extending arms of the levers, while the ends of the opposite arms of the
levers loosely engage a recess or recesses h in the periphery of a sleeve H, which
loosely surrounds the tubular stem of the outer valve-section. A collar I, fixed to
the tubular stem b above the sleeve H, forms an abutment for the upper end of the
sleeve and causes the stem to move upwardly with the sleeve. The tubular steni b
projects upwardly between the halls G and is provided at its upper portion with a
sleeve K, which loosely embraces it, the upper end of the sleeve K being provided
with a cap k, to the crown of which the upper end of the valve-stem c is secured,
so as to cause it to rise and fall with the rise and fall of the sleeve K.
The balls G are supported from above by spring-arms L, fixed at their upper ends
to the sleeve K and at their lower ends to the balls.
By the above construction it will be seen that as the balls are thrown apart by
the rotation of their support the levers g will be rocked in a direction to lift the valve-
section B, and simultaneously therewith the sleeve K will be drawn down by means
of the springs which connect it with the balls, and hence the valve-section will be
slid downwardly. The simultaneously-opposite movements of the outer and inner
valve-sections will tend to seat the inner section with great promptness, thereby
rendering the valve extremely sensitive and the length of travel of both sections very
small. This feature, taken in connection with the effectual balancing of the valves,
renders the frictional wear extremely slight. It will be further observed that the
spring bars which connect the balls with the sleeve K, and hence with the inner valve-
section, render the movements of the said inner section wholly free from the jerky
motion sometimes imparted to a vaive through a toggle or link connection, and because
of their fixed connection, with the sleeve K hold the balls in perfect alignment with
the axis about which they revolve.
The speed-regulator consists of a lever M, fulcrumed on a standard m, fixed to the
support D, one end of which is forked, the branches m¹ loosely engaging seats m²
in the opposite sides of the valve-stem b, and its opposite end resting upon a
plunger N, supported upon a spring n in a socket O. The tension of the spring n is
increased or diminished by a follower P, operated by a nut p. In the present instance
the follower itself forms the nut. Thus when the tension of the spring n is increased
the forked end of the lever M will be depressed, thereby drawing down on the stem b,
and hence upon the ends of the angle-levers g, and causing the balls to have a greater
resistance to centrifugal force, and hence increase the speed of the engine by rendering
the closing of the valves less easy to effect.
It is evident that slight changes might be resorted to in the form and arrangements
of the several parts described without departing from the spirit and scope of my
invention hence I do not wish to limit myself strictly to the construction and
arrangements herein set forth: but,
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 a governor, the combination, with a valve shell or casing, of an outer valve-
section, seated within the shell and provided with ports therethrough, an inner valve-
section and means for moving the valve-sections simultaneously, in opposite directions,
substantially as set forth.
2. In a governor, the combination, with a valve shell or casing and a tubular outer

page_text: valve-section seated within the shell or casing, the shell being provided with steam
passage-ways around the exterior of the valve-section, and the valve-section having
ports through its walls for the entrance and escape of steam, of an inner valve-section,
and means for simultaneously moving the valve-sections in opposite directions,
substantially as set forth.
3. In a governor, the combination, with an outer balance valve-section of a centri-
fugal force exerting a lift upon one of the valve-sections and a simultaneous depression
upon the other valve-section, substantially as set forth.
4. The combination, with a rotary support carrying the governor-balls and angle-
levers connecting the governor balls with the support, of an inner and outer balanced
valve-section, one of the sections having a stem in engagement with the said angle-
levers to slide it and the other valve-section having an independent sliding connection
with the governor-balls, substantially as set forth.
5. The combination, with a rotary support carrying the governor-balls and angle-
levers connecting the governor balls with the support, of valve-sections free to slide
relatively to each other, the stem of one of the valve-sections being engaged with the
said angle-levers, and the stem of the other valve-section being connected with the
governor-balls by spring-arms, substantially as set forth.
6. In combination, the outer balanced valve-section provided with a tubular stem,
the inner balanced valve-section having a stem located within the tubular stem of the
other valve-section, and the governor-balls connected from below with the tubular
stem by a pair of angle-levers and connected from above with the other valve-stem
by a pair of spring-arms, substantially as set forth.
7. In combination, the vertically sliding valve-stom, the governor-balls-suspended
by spring-arms and connected with the valve-stem by a pair of angle-levers, the speed-
regulating lever engaged at one end with the valve-stem, and an adjustable spring-
cushion exerting an upward lift upon the other end of the lever, whereby the valve-stem
may be depressed and the balls drawn toward each other by the engagement of the
stem with the angle-levers, substantially as set forth.
