page_text: LETTERS PATENT to Cyrus Eskrett and William Henry Searle both of Hull
in the County of York Oil Press Envelope Manufacturers for an Invention of
"IMPROVEMENTS IN ENVELOPES OR WRAPPERS USED
IN EXTRACTING OIL
FROM SEEDS
"
PROVISIONAL SPECIFICATION left by the said Cyrus Eskrett and William
Henry Searle at the Office of the Commissioners of Patents on the 6th June
1883.
CYRUS ESKRETT and WILLIAM HENRY SEARLE both of Hull in the County
of York Oil Press Envelope Manufacturers "IMPROVEMENTS IN ENVELOPES OR
WRAPPERS USED IN EXTRACTING OIL FROM SEEDS"
This invention relates to envelopes or wrappers used or employed for extracting
oil from Seeds and which are made from a substance or material known as
"vulcanized fibre" in which the necessary grooves or corrugations have been cut.
This our invention consists in the adaptation and combination of one or more
of the materials or substances hereinafter mentioned with the vulcanized fibre so
as to avoid the necessity of cutting grooves in the face of the said fibre and which
cutting weakens and renders the fibre liable to breakage, the fibre is also in a
great measure protected from the heat and a thin light and convenient envelope
is secured.
We employ in combination with vulcanized fibre a facing of corrugated wood,
corrugated paper or leather or we face the fibre with transverse spaced rope of
hemp, flax manilla cotton wool or cocoa nut fibre, the space or interval between the
roping forms an equivalent of the grooves or recessed part of the facing and
actual contact between the hot seed, bag and the vulcanized fibre is avoided. The
facing of corrugated wood (or of other materials herein mentioned) is secured to
the vulcanized fibre by means of longitudinal toothed angled plates secured to the
vulcanized fibre, the teeth being bent over so as to span or grip the edge of the
corrugated wood, or longitudinal angled strip of vulcanized fibre may be employed,
the usual longitudinal edging of horse hair or other material being employed along
each edge of the wrapper or envelopes.

the said Cyrus Eskrett and William Henry Searle in the Great Seal Patent
Office on the 6th December 1883.

This invention relates to envelopes or wrappers used or employed for extracting
oil from seeds and which are made from a substance or material known as
"vulcanized fibre" in which the necessary grooves or corrugations have been cut.
This our invention consists in the adaptation and combination of one or more
of the materials or substances hereinafter mentioned with the vulcanized fibre
and so constructed as to avoid the necessity of cutting grooves in the face of the
said fibre and which cutting weakens and renders the fibre liable to breakage,
the fibre is also in a great measure protected from the heat and a light and
convenient envelope is secured.
We employ in combination with vulcanized fibre a facing of corrugated wood,
corrugated paper or leather or we face the fibre with transverse spaced rope of
Hair hemp, flax, manilla. cotton. wool or cocoa nut fibre, the space or interval
between the roping forms an equivalent of the grooves or recessed part of the
facing and actual contact between the hot seed, bag and the vulcanized fibre is
avoided. The facing of corrugated wood (or of other materials herein mentioned)
is secured to the vulcanized fibre by means of longitudinal toothed angled plates,
secured to the vulcanized fibre, the teeth being bent over so as to span or grip the
edge of the corrugated wood, or longitudinal angled strip of vulcanized fibre may
be employed. or the usual longitudinal edging of horse hair or other material being
employed along each edge of the wrapper or envelopes.
The improved construction of envelope or wrapper will be fully understood by
reference to the annexed drawings and description thereof
Fig. 1 is a side elevation partly in section of our improved envelope or wrapper.
Fig. 2 is a plan view of the inner face of one half of an envelope or wrapper.
Fig. 3 is an end elevation of Fig. 2
Figs. 4. 5. shews modifications of construction having backing of thin sheet steel.
At A is the vulcanized fibre composing the backing of the envelope and B is the
facing of corrugated wood, paper, rope, or some one or other of the materials
herein referred to for such purpose-And the facing is secured to the vulcanized
fibre by means of the longitudinal toothed angle metal plates C the teeth D of
which are bent over so as to span or grip the edge of corrugated facing B, and
over the projecting edge, and along the teeth D is the twisted strand or edging of
horse hair E Another method of securing the corrugated facing B, is shewn at
the opposite edge of Fig. wherein is employed the bevelled longitudinal strip F
of vulcanized fibre wood or metal which when secured to the backing of vulcanized
fibre A secures the facing in position thereon. Another construction comprises
like combination of vulcanized fibre A (see Figs 4 and 5) secured to a thin metal
frame B (preferably thin sheet steel) the inner portion C, being composed of wood
(or other material herein referred to) forming the corrugated facing, and also the
main portion of the back of the wrapper the frame B forms the outer portion or
outline of the back of the envelope and prevents wear in introducing and removing

page_text: the wrappers to and from the press-It will be understood that both halves or
leaves of the envelope are provided with the metal frame B and constructed as
described.
Having thus fully described the nature and particulars of this our said invention
we would have it understood that what we claim is-
The combination of materials together with the construction of parts the whole
constituting the improved wrapper or envelope for purpose and as herein described
and illustrated by drawings annexed.
In witness whereof We the said Cyrus Eskrett and William Henry Searle
have hereunto set our hands and seal this 1 day of December in the year of
our Lord one thousand eight hundred and eighty three.
