Improvements in and relating to Centrifugal Governors.
1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
My invention has for its object certain new and useful improvements in
centrifugal governors, the purpose of which is to reduce as much as possible the
troublesome influence of the friction of the rotating parts of the governor against
the fixed parts of the same or of the several parts of the said governor the one
against the other.
My governor is composed of a shaft A which is rotated in any suitable way by
an engine, the speed of which is to be maintained constant. The said shaft A is
provided with a screw V in which gears a helicoidal wheel R which is rotated by
the said engine.
The lower end of the said shaft A is pivoted in a step bearing E in which
engages its pivot a' and its upper part is journalled in a fix tube D' screwed into
a bearing D fixed to the base F. On the upper portion a² of the shaft A is
attached in any suitable way, for instance by means of a flat or square on the said
shaft the middle of a spring B the two ends of which are fixed to the socket D³ of
the governor which is free to rotate around and to slide along a tube D'.
The spring B is provided with a weight B' which is intended to prevent any
excessive flexion of said spring, such flexion being liable to break the spring, and
with two masses or weights CC intended to act by means of the centrifugal force
upon the socket D like the usual weights of centrifugal governors. The said
socket D2 is moreover provided with a counter-weight P which follows every
movement of the same and which tends to bring the said socket D into its lower
position. The upper end a of the shaft A is provided with a lubricating box G
the interior of which is connected to the outer and inner surfaces of the fixed
tube D' by means of a central hole of the shaft A and of suitable radial holes of
the said shaft and of the tube D'.

1, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 invention has for its object certain new and useful improvements in

page_text: centrifugal governors, the purpose of which is to reduce as much as possible the
troublesome influence of the friction of the rotating parts of the governor against
the fixed parts of the same or of the several parts of the said governor the one
against the other.
My improved governor is illustrated in the drawing left with my Provisional
Specification.
The said governor is composed of a shaft A which is rotated in any suitable way
by an engine, the speed of which is to be maintained constant. The said shaft Å
is provided with a screw V in which gears a helicoidal wheel R which is rotated
by the said engine.
The lower end of the said shaft A is pivoted in a step bearing E in which
engages its pivot a and its upper part is journalled in a fixed tube D' screwed into
a bearing D fixed to the base F. On the upper portion a² of the shaft A is fixed
in any suitable way, for instance by means of a flat or square on the said shaft the
middle of a spring, B the two ends of which are fixed to the socket D² of the
governor which is free to rotate around and to slide along a tube D¹.
The spring B is provided with a weight B which is intended to prevent any
excessive flexion of said spring, such flexion being liable to break the spring, and
with two masses or weights CC intended to act by means of the centrifugal force
upon the socket D like the usual weights of centrifugal governors.
The said
socket D is moreover provided with a counter-weight P which follows every
movement of the same and which tends to bring the said socket D2 into its lower
position. The upper end a² of the shaft A is provided with a lubricating box G
the interior of which is connected to the outer and inner surfaces of the fixed
tube D by means of a central hole of the shaft A and of suitable radial holes of
the said shaft and of the tube D'.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is:-
1st. In a centrifugal governor the combination of a fixed tube D' with a shaft A
traversing the said tube through and through and with a socket D' traversed by
and rotating upon the said fixed tube D', substantially as and for the purpose
specified.
2nd. In a centrifugal governor the combination of a fixed tube D' with a shaft A
traversing the said tube through and through, a socket D' traversed by and
rotating upon the said fixed tube D' and with a spring B, fixed by its middle part
to the upper end of shaft A and by its lower ends to the socket D2 and having
a mass B and weights C and C' substantially as and for the purpose specified.
