An Improved Governor for Motors.
1, PERCY RICHARD JULIUS WILLIS, of 55 Chancery Lane, in the County of
London, Manager, do hereby declare the nature of this invention (a communication
to me from abroad by Sigel A. Royster, of Morocco, Ind., 'U.S.A., Inventor,) to
he as follows:
.1
The object of this invention is to provide a simple governor for controlling the
movement of motors..
The invention comprises two or more cylinders. fitted with pistons and piston-
rods connected to the motor by pitmen or the like to reciprocate said pistons.
Each cylinder is connected to an enclosed receptacle adjacent thereto, by a
perforation or tube opening into each end of the cylinder. This receptacle and
the cylinder contains a fluid (preferably, oil) which, as the piston is reciprocated, is
forced through the perforations from one end of the cylinder to the other; the
speed of the pistons and machinery, being regulated by the size of the oil passages.
The size of the passages can be regulated by means of a tap or the like. … … A-tube
or the like is inserted into the top or the side of each cylinder to form an air-vessel
into which the oil in the cylinders can expand in warm weather against the pressure
of air contained therein. The air pressure can be regulated by a screw-plug inserted
in the upper part of the tube, or air-vessel..

An impro
I, PERCY RICHARD JULIUS WILLIS of 55 Chancery Lane, in the County of
London Manager do hereby declare the nature of this invention (a communication
to me from abroad by Sigel A. Royster, of Morocco,, Newton County, Ind.,
U.S.A., Inventor) 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 governing mechanism for weight
motors; and it consists in cylinders filled with a fluid and having their opposite
euds connected by means of passages through which the liquid is forced back and
forth by means of pistons which operate in the cylinders, and a small chamber
connected with each cylinder in which air is compressed, all of which will be more
fully described hereinafter.
The object of my invention is to provide each cylinder with an expansion
chamber that is filled with compressed air, and into which the fluid in the cylinder
expands during warn weather, and which supplies air to the cylinder during cold
weather when the fluid has contracted, and thus prevents a vacuum from being
formed, and causing an even regular motion to the operating parts.
In the accompanying drawings:-
Figure 1 is a perspective view showing my invention applied to the fluid governor
of a weight motor.
Eio 2 is a horizontal section of one of the cylinders.

page_text: 1 represents a frame having a standard 2 aud provided at its top with a pulley 3
over which passes a rope or cable 4 which has one end attached to, and carrying a
weight 5, and which has its other end secured to a drum 6 of a winding shaft 7
which is connected by a suitable clutch with a crank wheel 8. The crank wheel 8
is a gear wheel, and is connected by suitable gearing with a drive wheel 9, from
which may be run a belt for driving or operating any suitable light machinery.
The crank wheel is connected by pitmen 10, and 11 with piston rods 12 and 13
of pistons 15 which operate in the cylinders 16 and 17. These two cylinders are
placed at right angles to each other and they contain a suitable fluid such as heavy
oil for retarding the reciprocation of the pistons.
Each cylinder is provided with an extension 18 of its casing, which extension is
provided with a passage 19 having its ends terminating at the ends of the cylinder,
so as to cause the oil or other fluid to circulate and be forced by the piston from
one end of the cylinder to the other. The circulation of the oil or other fluid is
regulated by a cock or valve 20, which is mounted in an opening 21 of the
extension 18. By turning this cock the speed of the falling weight is controlled.
Two cylinders are preferably used and they are so arranged with relation to
each other that when one piston is at the end of a stroke the other has started and
is subjected to the full resistance of the oil or other fluid.
Each cylinder is provided with a chamber 23 into which air is compressed to
any suitable degree, and which chamber serves to allow the fluid to expand into it
during warm weather, and to supply air to the cylinder during cold weather when
the fluid has contracted, and thus prevent a vacuum from being formed. If the
fluid expands the cylinder is liable to be injured or leakage take place, and if the
fluid contracts a vacuum will be formed in the cylinder, and all regularity of action
destroyed.
"
"
Where oil or water is used in the cylinders these chambers 23 are absolutely
necessary to automatically regulate the expansion and contraction.
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 :-
In a governor mechanism, the combination of a drive, wheel, of fluid containing
resistance cylinders placed at an angle to each other, valve controlling ducts or
channels connecting opposite ends of each of said cylinders, pistons fitting in the
cylinders, pitmen connecting the piston rods to a common crank pin ou the drive
wheel, and tubular chambers 23 communicating with the interior of the cylinders,
said chambers being partially filled by the fluid in the cylinders, the remaining
part of the chambers holding compressed air, substantially as specified.
Dated this 23rd day of January 1896.
