PROVISIONAL SPECIFICATION.
Improved Automatic Steam Governors.
I, THOMAS SAINT of 8 Cantrell Road, Bow Common, in the County of
Middlesex Pattern Maker, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to govern or control the admission of steam
supplied to engines or mechanical contrivances. This I effect by means of an
improved governor which is actuated by the passage of the steam through the
supply pipe. At or near the engine and farthest from the boiler I affix a cylinder
and piston. This piston or the rod connected thereto moves a lever or series of
levers connected with the governor valve. It is mounted just above or outside the
circumference of the pipe, and as the steam gathers the piston and rod is raised.
Levers acting on loose or knuckle joints and properly counterpoised and weighted
are fixed connecting the end of the piston rod with the rod or arm of the governor
valve. This valve is made of conoidal or other shapes with the scating hollowed
or fashioned out so as to prevent the passage of steam when the valve is closed.
The rod of the valve is moved by a lever placed with a bracket fulcrum on one
side and a bracket guide on the other and controlled by the movement of the
counterpoised levers aforementioned. The effect of this mechanism is that when
the steam is admitted too freely the piston is raised and when the pressure is
reduced it subsides to its normal position.

Improved Automatic Steam Governors.
I, THOMAS SAINT formerly of 8 Cantrell Road Bow Common, but now of
49 Burgess Street St. Paul's Road Limehouse in the County of Middlesex
Pattern Maker, 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 :—
The object of my invention is to govern or control the admission of steam
supplied to engines or mechanical contrivances. This I effect by means of an
improved governor which is actuated by the passage of the steam through the
supply pipe.
At or near the engine and farthest from the boiler I affix a cylinder and piston
(lettered H on the drawings appended to this Specification) fitted with stuffing-box.
This piston H, or the rod connected thereto moves a lever T. hereinafter called the
bottom lever which acts upon a bell crank K causing it to oscillate or travel back-
ward or forward. By the oscillation of the bell crank K another or top lever G. is
allowed to move up or down. The piston and rod is mounted just above or outside
the circumference of the pipe and as the steam "gathers" the piston H and rod are
raised. Levers acting on loose or knuckle joints S. properly counterpoised and
weighted and lettered on the drawings T. and G. respectively are fixed connecting the
end of the piston rod with the rod or arm of the governor valve. This valve is made
of conoidal or other shapes with the seating hollowed or fashioned out so as to
control the passage of steam when the valve C. is moved. The rod of the
valve C. is actuated by the top lever G controlled by the movement of the

page_text: bottom lever T. and the bell crank K. and the rod and valve C. is raised when
steam is admitted too freely, and when the pressure is reduced it subsides to its
normal position.
In the drawings appended A. represents the steam pipe, B. the inlet pipe from
boiler, C. regulating valve, D. piston actuating the regulating valve, E. and E.
the fulcrum brackets, F and F the guide brackets, G. the top lever connected with
the valve rod, H. equilibrium piston, I. I. stuffing box, J. J. glands, K. bell
crank, L. link connecting bell crank and bottom lever, M. weight carriage, N.
weight. T the bottom lever and Q the knuckle joints.
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
1. A governor valve for steam supply, actuated and controlled by the passage of
steam through the supply pipe acting with pistons, levers and weights as described
and illustrated substantially, and as set forth.
