IMPROVEMENTS IN STEAM ENGINE GOVERNORS
Year: 1853

page_text: LETTERS PATENT to Ellen Jones, of Palace Street, Pimlico, in
the County of Middlesex, Widow and Administratrix of William
John Thomas Jones, of Palace Street aforesaid, deceased, for the
Invention of "IMPROVEMENTS IN STEAM ENGINE GOVERNORS," being
the same Invention for which Letters Patent were granted to her
late husband on the Fourteenth day of April last.
Sealed the 12th December 1858, and dated the 17th October 1853.
PROVISIONAL SPECIFICATION left by the said Ellen Jones at
the Office of the Commissioners of Patents, with her Petition, on
the 17th October 1853.
I, ELLEN JONES, of Palace Street, Pimlico, in the County of Mid-
dlesex, Widow and Administratrix of William John Thomas Jones, of
Palace Street aforesaid, deceased, do hereby declare the nature of the
Invention for IMPROVEMENTS IN STEAM ENGINE GOVERNORS" to be as
follows:-
This Invention consists of applying springs, acting on a piston in a
cylinder, to prevent the prejudicial effect of any sudden action of a
governor. The springs receive the first effort of any sudden action, and
tend to neutralize it.

filed by the said Ellen Jones in the Great Seal Patent Office
on the 17th April 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ELLEN JONES, of Palace Street, Pimlico, in the County of Middlesex,
Widow and Administratrix of William John Thomas Jones, of Palace
Street aforesaid, deceased, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventeenth day of October, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign,-did,-for- Herself, Her heirs and suc-
cessors, give and grant unto me, the said Ellen Jones, Her special
licence that I, the. said Ellen Jones, my executors, "administrators,
and assigns, or such others as I, the said Ellen Jones, my executors,
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
STEAM ENGINE GOVERNORS," that the said Invention is the same as that
for which Letters Patent were granted to my late husband on the
Fourteenth day of April last, upon the condition (amongst others) that
I, the said Ellen Jones, by an instrument in writing under my hand
and seal, 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 immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Ellen Jones, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof (that is to say):
This Invention consists of applying springs, acting on a piston in a

page_text: cylinder, to prevent the prejudicial effect of any sudden action of a
governor. The springs receive the first effort of any sudden action, and
tend to neutralize it...
-
Having thus stated the nature of the said Invention, I will pro-
ceed to describe the manner of performing the same.. The Invention
consists of employing..springs, and by preference in such manner
that one acts by compression and the other by extension, and
the action of the governor is regulated by these springs through
the lever, by which the connection is usually made between the
governor and throttle valve. The form of the springs may be varied,
but 1 believe helical or spiral springs to be the best for the purpose,
and it is preferred that they should be arranged as is shewn in the
Drawing.
:
C, C,
this
Figure 1, is an external elevation; and Figure 2, an elevation in
section. a, is the spring for acting by extension, fastened to the
bottom of a small cylinder F, which in usc is bolted to the floor
or other convenient place. b, is the spring to resist compression,
placed in the same cylinder, but pressing against the cover.
is the rod connecting the governor gear with the springs;
rod is made fast at its lowest end to the upper end of the lower
spring, and the other end of the lower spring is made fast to
the lower end of the cylinder. On the lower end of rod c, is
formed an enlargement or piston c', which slides freely in the
cylinder F. The upper spring is placed on the rod c, above the
piston or enlargement c¹, the upper end of the spring coming
against the under side of the cover of the cylinder; hence any
effort to raise the rod c, causes the upper spring to be compressed,
and the under spring to be extended. The governor lever is con-
nected to c, by a socket d. It should be remarked, that although it
is preferred to have the two springs in each apparatus acting as above
described, it is not essential that such should be the case, as one only
may be used.
Having thus described the nature of the Invention, and the manner
of performing the same, I would have it understood that I make no

page_text: claim to the parts separately; but what I claim is, the combination
of parts herein described.
In witness whereof, I, the said Ellen Jones, have hereunto set
my hand and seal, this Seventeenth day of April, in the year of
our Lord One thousand eight hundred and fifty-four.
Witness,
