Automatic Uniform Speed Regulator for Governors.
I, FREEMAN N. SAYLOR of the Town of Strathroy, in the County of
Middlesex, in the Province of Ontario, Canada, Electrician, 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:-
Nearly all swinging ball governors of a steam engine, are provided with a
resistance to their centrifugal force.
This resistance is usually in the form of a weight or spring, which is regulated
by hand, that is when the load is increased, the resistance has to be increased,
and vice versa to make the revolutions of the governor uniform, under various loads
or steam pressures.
My invention consists of a device, by which this resistance is regulated auto-
matically, and simultaneously with the governor, to establish a uniform rate of
revolution to said governor, under various loads or steam pressures.
Reference being had to the accompanying drawings, wherein
Fig. 1. is a side elevation of a governor, illustrating my invention, in connection
therewith, and showing the governor in its upper position.
Fig. 2. is another view of the same, showing the governor in its lower position.
Fig. 3. is another view of the same, showing the governor in its intermediate
position.
A, designates any suitable support.
B, a lever, one end of which is pivotally secured to any suitable support, such
as, A.
.
C, designates a weight or a spring may be used which may be secured to, or
formed integral with said lever about midway between its ends.
H, designates a radial arm, pivotally secured at one end to the lower end of the
bell crank, F.
E, designates a coupling link, which is pivotally secured to, and connects the
lever, B, with the radial arm, H.
D, designates a hanger or link, which is pivotally secured at one end to any
suitable support, such as, A, the other end being pivotally secured to the radial
arm, H, and link, E.
F, designates a bell or other multiple crank, pivoted on any suitable support,
such as, A.
G, is a rod, which connects the swinging governor balls, with one end of the bell
or multiple crank, F.
I, designates a support, which not only guides the rod, G, but from the upper
end of which, the governor balls; J, are supported.
K, designates a rod, which may be at any angle, to transmit the action of the
governor to the apparatus, which trip the steam valves of an automatic cut off
engine; as shown in the accompanying drawing, this rod, K, is attached to the
lower end of the bell crank, but this rod or rods, K, may be attached to the bell
crank, F, or to any multiple crank, at any point, as found most suitable or con-
venient under the circumstances, when this device is applied to different classes of
engines, or water wheels.
The operation of my invention is as follows,-
When the load of a steam engine is increased, the centrifugal force of the
governor is reduced, and the resistance to this centrifugal force is increased,
because the radial arm, H, is brought to a more horizontal position.
And when the load of a steam engine is reduced, the centrifugal force of the

page_text: governor is increased, and the resistance to this centrifugal force is reduced,
because the radial arm, H, is brought to a more vertical position.
As the centrifugal force of the governor changes, and operates the weight, C,
through the radial arm, H, lever, B, and links, D, E, the operation of these links
and levers, assist said governor to move and control the vertical adjustment of the
said weight.
As a result, my device would permit the engine to run at a uniform rate of
speed under various loads and steam pressures, within the capacity of the engine.
-I do not wish to confine myself to the special arrangement of the parts, as shown
in the accompanying drawings, as they may be varied at will, as found most
suitable or convenient under the different circumstances, connected with attaching
this invention to different classes of engines, or water wheels, provided with different
governors.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
1st. The application to a centrifugal ball governor of a device by which the
resistance to the centrifugal force of said governor, is automatically and simul-
taneously varied, that is, increased or diminished as required, with said governor
to establish its uniform revolution, substantially as shown and described, and for
the purpose specified.
2nd. A radial arm, H, or its substantial equivalent, and the application of a
weight, C, to said arm, H, and means for connecting the latter with the governor,
substantially as shown and described, and for the purpose specified.
3rd. A radial arm, H, or its substantial equivalent, pivoted on a suitable bell
or multiple crank, F, and means for connecting the latter with the governor, and
the application of a weight, C, to said arm, H, substantially as shown and described,
and for the purpose specified.
4th. A radial arm, H, or its substantial equivalent, pivoted on a suitable bell
or multiple crank, F, and means for connecting the latter with the governor in
combination with a hanger or link, D, and the application of a weight, C, to said
arm, H, substantially as shown and described, and for the purpose specified.
5th. A radial arm, H, or its substantial equivalent, a suitable bell or multiple
crank, F, and means for connecting the latter with the governor, a lever, B,
provided with a weight, C, about midway between its ends, and a link, E,
substantially as shown and described, and for the purpose specified.
6th. An automatic uniform speed regulator for governors, consisting of a radial.
arm, H, hanger or link, D, lever, B, and link, E, in combination with a weight, C,
and means for connecting these devices with the governor, substantially as set,
forth.
7th. A radial arm, H, or its substantial equivalent, and a bell or multiple
crank, F, in combination with the hanger or link, D, link, E, lever, B, and
weight, C, and means for connecting these devices with the governor, substantially
as shown and described, and for the purpose specified.
