Year: 1872

page_text: LETTERS PATENT to John Hartmann August Gericke, of New York
City, State of New York, United States of America, for the
Invention of "IMPROVEMENTS IN GOVERNORS.”
PROVISIONAL SPECIFICATION left by the said John Hartmann August
Gericke at the Office of the Commissioners of Patents, with his
Petition, on the 28th September 1872.
I, JOHN HARTMANN AUGUST GERICKE, of New York City, State
5 of New York, United States of America, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN GOVERNORS," to be as
follows:-
This Invention relates to improvements in fluid governors, and it is
intended particularly to facilitate the construction of these governors,
0 and also to reduce the friction and so give a greater pressure with
fewer revolutions.
My improvements consist in the arrangement of a reservoir with
a cover, and an enclosed turbine or reaction wheel receiving motion from

page_text: the engine. The reservoir and cover are provided with flanges for the
purpose of being fastened together, the cover of the said reservoir being
bored out and faced to receive a bevel gear wheel shaft and stuffing box;
the reservoir receives a turbine or reaction water wheel which is
mounted on a shaft that has its bearing at one end in a socket in the
hub of stationary guide curves, while its other end extends through the
stuffing box in the cover, and then through the bevel gear wheel in which
the shaft forms a square. In the said square friction rollers are inserted
which have the form of balls connected at their ends; the upper end of
the shaft is turned to an antifriction point to receive a step for the
connection of a weighted lever working the throttle valve in such a
manner that when the speed of the engine increases beyond the desired
point the pressure of the fluid brought to bear on the governor piston or
turbine wheel by the action of the quick turning turbine water wheel
closes the throttle valve; and when the speed of the engine decreases
this action is reversed.
The vanes or paddles on the aforesaid turbine wheel are made in
three, four, or more systems; that is to say, three of them extend from
near the centre to the circumference of the wheel; three of them extend
from the centre about one-fourth to the circumference of the wheel,
three of them extend from the centre about one-half to the circum-
ference of the wheel, and the remaining three extend from the contre
about three-fourths to the circumference of the wheel, Their upper cnds
extend radially from the wheel, and are cut in horizontal planes, and their
lower ends are bent to tangential lines on the circumference of the
wheel. Outside of the vanes the said wheel receives a jacket cast
solid with the wheel. Through this jacket all the slip of the fluid or
water is prevented.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of September, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Hartmann August Gericke, Her
special licence that I, the said John Hartmann August Gericke, my
exccutors, administrators, and assigns, or such others as I, the said Jolin
Hartmann August Gericke, my exccutors, administrators, and assigns,
should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN GOVERNORS," upon the con-
dition (amongst others) that I, the said John Hartmann August Gericke,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme.
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Hartmann August Gericke, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement, reference being had to the accompanying
Drawing forming a part of this Specification.
This Invention relates to improvements in fluid governors, and it is
intended particularly to facilitate the construction of these governors, and
also to reduce their friction and so give a greater pressure with fewer
revolutions.
The said improvements consist in the arrangement of a reservoir
with a cover, and an enclosed turbine or reaction wheel receiving motion
from the engine. The reservoir and cover are provided with flanges for
the purpose of being fastened together, the cover of the said reservoir is
bored out and faced to receive a bevel gear wheel shaft and stuffing box,
and the reservoir receives a turbine or reaction water wheel which is
mounted on a shaft that has its bearing at one end in a socket in the
hub of the stationary guide curves, while its other end extends through

page_text: a stuffing box in the cover and then through the bevel gear wheel in
which the shaft forms a square. In the said square friction rollers are
inserted which have the form of balls connected at their ends, the
upper end of the shaft is turned to an antifriction point to receive a step
for the connection of a weighted lever working the throttle valve in such
a manner that when the speed of the engine increases beyond the
desired point the pressure of the fluid brought to bear on the governor
piston or turbine wheel by the action of the quick turning turbine
water wheel closes the throttle valve; and when the speed of the engine
decreases this action is reversed.

page_text: case A in which the turbine wheel works is bored out to receive the
turbine or reaction wheel B, detached views of which are shown in
Figures 3 and 4; B represents a turbine wheel consisting of a hollow
truncated cone inverted with vanes or paddles m, n, o, and p; the wheel
is mounted on a shaft F which has its bearing at one end of the hub d
of the case A, while its other end extends through the cover c which is
provided with a stuffing box X and a tube e; a stand P and the guide
curves at its base, which project into the reservoir and are cast solid
with the cover, the stand projecting outside and above as shewn in
Figure 1. On the shaft F is mounted a bevel gear wheel K which
transmits the motion received by the shaft N and bevel wheel S from the
engine to the turbine or reaction wheel.
In the bevel gear wheel K the shaft F forms a square with rollers Q
inserted, and connected at their ends as shown in Figures 5 and 6; the
upper end of the shaft F meets the weighted lever D to which it is so
connected as to be capable of rotary motion, as well as longitudinal
motion; the lever D connects with the throttle valve.
The vanes or paddles on the turbine wheel B are shewn detached in
Figures 3 and 4; Figure 3 being a top view and Figure 4 a side view,
both with the jacket removed. These vanes are made in three, four, or
more systems, that is to say, three of them m extend from near the
centre to the circumference of the wheel; three of them n extend from
centre about one-fourth to the circumference of the wheel; three of
them o extend from the centre about one-half to the circumference of
the wheel; and the remaining threo p extend from the centre about
three-fourths to the circumference of the wheel. Their shapes are seen in
Figures 3 and 4; their upper ends extend radially from the wheel and
are cut in horizontal planes; their lower ends are bent to tangential
lines on the circumference of the wheel; outside of the vanes is a
jacket II cast solid with the wheel as shewn in Figures 1, 3, and 4,
through this jacket H all the slip of the fluid is prevented.
The long paddles m take the water first near the centre of the shaft
and move it outward and downward towards the circumference of the
wheel, next after them the paddles n and o, and then the paddles p
take the water or other fluid, and so compress the same in the cells
of the case A, and underneath the hollow cone of the turbine wheel B,
so that the same is elevated and driven against the cover c of the case

page_text: A. By combining the guide curves of the case A and the turbine
wheel B, the fluid to be compressed is conducted to and from the
wheel with the least possible friction, and by enabling the fluid to excrt
its full power on the bottom of the wheel a governor is produced
which gives a correct result, and furthermore by securing all the
parts which are liable to wear outside easy access can be had to them.
Having thus fully described the said Invention, and the manner of
performing the same, I wish it understood that I claim, the combination
of the reservoir A. with the guide curves f, g, h, and 6, the wheel B with
the paddles m, n, o, and p, the jacket II, the rollers Q, and the shaft F
working in a square of the gearing in the manner herein described.
