IMPROVEMENTS IN 'ENVELOPES' OR 'HAIRS USED IN EXTRACTING OIL FROM OLEAGINOUS SEEDS, AND IN OIL CAKE MAKING
Year: 1869

page_text: LETTERS PATENT to Cyrus Eskrett, Oil Mill Foreman, and Henry
Searle, Wood Turner, both of Kingston-upon-Hill, in the County
of York, for the Invention of "IMPROVEMENTS IN 'ENVELOPES' OR
'HAIRS USED IN EXTRACTING OIL FROM OLEAGINOUS SEEDS, AND IN OIL
CAKE MAKING."
PROVISIONAL SPECIFICATION left by the said Cyrus Eskrett and
Henry Searle at the Office of the Commissioners of Patents, with
their Petition, on the 16th September 1869.
We, CYRUS ESKRETT, Oil Mill Foreman, and HENRY SEARLE, Wood
Turner, both of Kingston-upon-Hull, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN
ENVELOPESOR 'HAIRS USED IN EXTRACTING OIL FROM OLEAGINOUS SEEDS,
AND IN OIL CAKE MAKING," to be as follows:-
Our Invention consists in the use and adaptation of strips or pieces.
of wood fitted together so as to form a corrugated plate or board of a
form similar to the face of the hair now in general use for seed crushing
and cake making purposes. We make each corrugation out of a

page_text: separate piece of wood, and put as many such pieces together as may
be required to make up the proper length for the size of cake wanted,
but we can also make each board out of one piece of timber, or any
number of pieces. We strip the corrugation from each side of the board
say, for example, about three quarters of an inch wide and one quarter
deep, and fix a hair rope or piece of leather, wood, or other similar
substance in the "chicks" or grooves thus formed, we generally use
two such boards, one to be placed above the cake, and the other beneath.
While in the press both boards should be attached to each other at the
one end by a leather strap or any other suitable means.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Cyrus Eskrett and Henry Searle in the Great Seal
Patent Office on the 15th March 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CYRUS
ESKRETT, Oil Mill Foreman, and HENRY SEARLE, Wood Turner, both of
Kingston-upon-Hull, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date. the Sixteenth day of September, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Cyrus Eskrett and Henry Searle, Her
special licence that we, the said Cyrus Eskrett and Henry Searle, our
executors, administrators, and assigns, or such others as we, the said
Cyrus Eskrett and Henry Searle, our 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 ENVELOPES'
OR 'HAIRS USED IN EXTRACTING OIL FROM OLEAGINOUS SEEDS, AND IN OIL CAKE
MAKING," upon the condition (amongst others) that we, the said Cyrus
Eskrett and Henry Searle, our executors or administrators, by an in-
strument in writing under our, 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

page_text: 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 we, the said Cyrus Eskrett and Henry Searle,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
Our Invention consists in constructing an apparatus in the manner
hereafter described which shall serve the purpose of the ordinary
"hairs
now used in extracting oil from oleaginous seeds and in oil cake
making, such hairs being very expensive and uneconomical, whilst our
apparatus will be found economical and efficient. We construct our
envelopes or "hairs" by fitting together strips or pieces of wood, so as
to form a corrugated plate or board, of a form similar to the face of the
hair now in general use for seed crushing and oil cake making purposes.
Each corrugation should be made out of a separate piece of wood placed
transversely, and as many such pieces should be put together as may be
required to make up the proper length for the size of cake required to
be produced by the use of the "hairs." These "envelopes" or "hairs "
can however be made out of one piece of timber, or any number of
picces. At each side or edge of the board which may be say for example
about / inch wide, we fix instead of the corrugated board or corrugated
pieces a hair rope or piece of leather or other similar yielding sub-
stance, or we even use wood or other such like substance. Two such
boards are .to be used, one to be placed above the cake and the other
beneath, and while in the press both boards should be attached to each
other.
Having thus far particularly described the nature of our said Invention
and intimated generally in what manner the same is to be performed or
put in practice, we now proceed to particularly describe and ascertain
in what manner the same is to be performed or put in practice, which
we shall do by reference to the accompanying Drawings, that is to
Fig. 1, face view of our improved envelope open, a few only of the
corrugations being shewn; Fig. 2, edge view closed; Fig. 3, back view
closed; Fig. 4, section showing corrugation.

page_text: In the said Figures, A denotes the corrugated part; B, the horse-hair
edge; C, hinges; D, handle for putting in and taking out the envelope
from the press; E denotes the stitching (through the board) for
securing the hair rope in position; F, F, end plates through which the
ends of the bolts G, G, (dotted lines) pass, which also pass through the
corrugated board longitudinally and are secured by screw nuts as
shown.
Having now particularly described and ascertained the nature and
object of our said Invention and in what manner the same is to be per-
formed or carried out in practice, we hereby declare that we claim the
"Improvements in Envelopes' or 'Hairs' used in Extracting Oil from
Oleaginous Seeds, and in Oil Cake Making," an important feature of
which improvements is the use of corrugated pieces or corrugated board
with the corrugations running transversely.
In witness whereof, we, the said Cyrus Eskrett and Henry Searle,
have hereunto set our hands and seals, this Twelfth day of March,
in the year of our Lord One thousand eight hundred and seventy.
Witness to the signing by the
said Cyrus Eskrett and Honry
Searle,
