Wilts, Machinist, for the Invention of "IMPROVEMENTS IN PRESSES
OR APPARATUS FOR PRESSING CHEESE AND OTHER ARTICLES OR SUBSTANCES."

PROVISIONAL SPECIFICATION left by the said Eli Oatley at the Office
of the Commissioners of Patents, with his Petition, on the 18th
August 1871.
I, ELI OATLEY, of Melksham, in the County of Wilts, Machinist, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PRESSES OR APPARATUS FOR PRESSING CHEESE AND OTHER ARTICLES OF SUB-
STANCES," to be as follows:-
My Invention relates to presses which are required to act with a con-
tinuous and graduated pressure, and consists in substituting for the
levers and weights ordinarily employed in such presses a spiral spring,
which is compressed by the rising of a nut worked by the ordinary
vertical screw, and thereby caused to act with a gradually increasing
force on the cheese or other article or substance required to be pressod

page_text: by the further turning of the screw. For this purpose the screw is
caused to pass through the space in the middle of the spring, which is
contained in a box or chamber cast with or fixed to the cross head of
the press, one end of the spring resting against the upper closed part of
the said chamber, and the other end being connected to the nut. This
nut has on each side a rib or projection capable of sliding in a groove
correspondingly situated in the interior of the said chamber, thereby
guiding the nut in its upward motion. Fixed to the nut is an indicator,
which projects through a slot formed in a graduated brass plate fixed to
the front of the said chamber, by which the varying pressure of the
spring is indicated. By means of the above stated combination of a
spiral spring with the ordinary vertical screw when this screw has been
worked downwards until the "follower" at the bottom is caused to rest
on the cheese or article or substance to be pressed, by a further turning
of the screw by means of a hand wheel the nut is worked upwards in
the grooves of the chamber and caused to compress the spring.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Eli Oatley in the Great Seal Patent Office on the
17th February 1872.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ELI
OATLEY, of Melksham, in the County of Wilts, Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighteenth day of August, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Eli Oatley, Her special
licence that I, the said Eli Oatley, my executors, administrators, and
assigns, or such others as I, the said Eli Oatley, my executors, adminis-
trators, 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 PRESSES
OB APPARATUS FOR PRESSING CHEESE AND OTHER ARTICLES OR SUBSTANCES," upon
the condition (amongst others) that I, the said Eli Oatley, my executors

page_text: 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 immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Eli Oatley, 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 :—
The object of my Invention is to improve the construction of those
presses which are required to act with a continuous and graduated
pressure, to effectuate which object I substitute for the levers and
weights ordinarily employed in such presses a spiral spring, which can
be compressed by the use of a nut worked by the ordinary vertical
screw, and thereby caused to act with a gradually increasing force on
the cheese or other article or substance required to be pressed by the
further turning of the screw. This screw passes through the space in-
the middle of the spring, contained in a box or chamber cast with or
fixed to the cross head of the press, one end of the spring resting against
the upper closed part of the said chamber, the other end being connected
to the nut. This nut has on each side a rib or projection capable of
sliding in a groove correspondingly situated in the interior of the said
chamber, thereby guiding the nut in its upward motion. Fixed to the
nut is an indicator, which projects through a slot formed in a graduated
brass plate fixed to the front of the said chamber, by which the varying
pressure of the spring is indicated. By means of the above stated.
combination of a spiral spring with the ordinary vertical screw when
this screw has been worked downwards until the "follower" at the
bottom is caused to rest on the cheese or article or substance to be
pressed, by a further turning of the screw by means of a hand wheel.
the nut is worked upwards in the grooves of the chamber and caused.
to compress the spring, and thus accomplish the object of my Invention.
.
In and by the foregoing statement I have particularly described and
ascertained the nature of my said Invention, as required by the afore-
said condition in the said Letters Patent contained, and therein have
incidentally supplied a description in general terms of the manner in
which the said Invention is to be performed or carried out; but I will

ments, and elevation of remainder of press; Fig. 3, sectional plan of 5
spring box and nut.
In these Figures A denotes the pillars of the press; B, slides or
guides; C, hand wheel for turning screw rod for compressing or for
relieving pressure; D, screw rod; E, the nut above mentioned; F, the
above-described spiral spring, one end abutting against the top of the 1
box (H), and the other end on nut (E); G, cross head, on which the
box (H) is cast or fixed, which box contains the spring and nut, as
shown; H, box above mentioned; J, indicator fixed to the nut, as above
described; K, stand of wood, iron, or other material.
Having now particularly described and ascertained the nature and 1
object of my Invention, and in what manner the same may be per-
formed or carried out in practice, I hereby declare that I claim, the
herein described "Improvements in Presses or Apparatus for Pressing
Cheese and other Articles or Substances," the nature whereof is described
by the words preceding the words Description of the Drawings.
In witness whereof, I, the said Eli Oatley, have hereunto set my
hand and seal, this Third day of February, in the year of our
Lord One thousand eight hundred and seventy-two.
