Year: 1874

page_text: LETTERS PATENT to Peter Mesick, of Piccadilly, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN THE METHOD OF AND
MEANS FOR THE PRODUCTION OF BOXES AND OTHER HOLLOW ARTICLES FROM
PAPER PULP."-Partly a communication from abroad by Seth
Wheeler and Edgar Jerome, both of Albany, State of New York,
United States of America.
Scaled the 10th November 1874, and dated the 13th May 1874.
PROVISIONAL SPECIFICATION left by the said Peter Mesick at the
Office of the Commissioners of Patents, with his Petition, on the
13th May 1874.
I, PETER MESICK, of Piccadilly, in the County of Middlesex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE METHOD OF AND MEANS FOR THE PRODUCTION OF BOXES AND OTHER HOLLOW
ARTICLES FROM PAPER PULP," (the result partly of a communication to me
from abroad by Seth Wheeler and Edgar Jerome, both of Albany, State

page_text: of New York, United States of America, and partly my own Invention,)
to be as follows :-
The object of this Invention is to produce boxes and other hollow
articles from paper pulp by machinery operating substantially according
to the mode described in the Specification of the Patent granted, on the
7th May, 1873, No. 1649, to Seth Wheeler and Edgar Jerome, and
this present Invention, which comprises improvements thereon, is as
follows: Paper pulp is admitted within a mould in a definite quantity,
and the supply is then shut off by any convenient automatically worked
slide or other valve, or equivalent means for the purpose. This said
mould is made of india-rubber or other suitable elastic or contractible
material, and is so constructed or actuated that it can be made to
contract on a form placed within it, on which form the paper pulp
deposits itself. With this object the mould may be made with hollow
walls or sides, and be contracted by forcing air or other fluid into the
said hollow walls or sides, the mould being held in an outer solid ring or
box.
The form on which the pulp is deposited is made flexible or elastic,
and perforated or permeable, and may be made in one or more parts. It
may be made in two parts, the perforated bottom and the circumference,
the latter of such a form and material as to be flexible, or contractible
or collapsible, and perforated or otherwise formed with interstices or
channels. It might for instance be made of thin perforated segments
or sections, held together by an outer thin perforated ring, the said
segments or sections being so formed and fitted together in conjunction
with an inner conical ring as to be easily removed when the inner ring
is withdrawn. The form is placed on a form carrier, through which the
water from the pulp escapes.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Peter Mesick in the Great Seal Patent Office
on the 13th November 1874.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of May, in the year

successors, give and grant unto me, the said Peter Mesick, Her special
licence that I, the said Peter Mesick, my executors, administrators,
and assigns, or such others as I, the said Peter Mesick, 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
THE METHOD OF AND MEANS FOR THE PRODUCTION OF BOXES AND OTHER HOLLOW
ARTICLES FROM PAPER PULP," (the result partly of a communication to me
from abroad by Seth Wheeler and Edgar Jerome, both of Albany, State
of New York, United States of America, and partly my own Invention,)
upon the condition (amongst others) that I, the said Peter Mesick, my
executors 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 Peter Mesick, 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, reference being had to the accompanying Drawings,
and to the letters of reference marked thereon, that is to say:—
The object of this Invention is to produce boxes and other hollow
articles from paper pulp by machinery operating substantially according
to the mode described in the Specification of the Patent granted on the
7th May, 1873, No. 1649, to Seth Wheeler and Edgar Jerome, and
this present Invention, which comprises improvements thereon, is as
follows Paper pulp is admitted within a mould in a definite quantity,
and the supply is then shut off by any convenient automatically worked
slide or other valve, or equivalent means for the purpose. This said

page_text: in one direction, viz., towards the centre. C is a spring of steel or other
suitable material, held within the hollow mould B and caused to contract
to a smaller diameter around the mass of pulp admitted within it. This
spring may be made very thin, with overlapping ends, or else as shown.
here; its object is to ensure the regular formation of the paper box. If
the india-rubber mould B were not provided with such an inner ring C
any irregular bulging of the mould B when contracted might prevent
the regular formation of the paper box. d is a three-way cock having a
side opening for the escape of the fluid from the hollow mould B after
each operation:
Figure 3 is a plan of another form of mould. The innermost circle
represents the form carrier on which the perforated form is placed, the
pulp being deposited on the outside of the said perforated form. C is a
solid ring of india-rubber or other suitable flexible contractible material;
B is an open spring of steel or other suitable material or metal; F, F,
are the compresser segments, which by knuckle joint mechanism or
other suitable means are made to move towards the centre for com-.
pressing or contracting the mould rings B and C on to the pulp on tho
form carrier..
.

Fig. 4 shews a form carrier H with ferrule I for adapting itself to
forms of various depth; J is the form. Figure 5 is a plan view of the
latter, which is made in four sector-shaped sections or pieces, with
numerous perforations for drawing off the water from the pulp deposited
thercon. The carrier H is open at the top in case a form of thick,
substance is used, such as here described with reference to Figs. 4 and 5,
but otherwise it may have the upper surface of the carrier H perforated
with numerous small holes; the carrier has grooves in the circumference,
as shewn. This part is also perforated with many small holes, which are
situated in the grooves. Suction being applied to the interior of the
form carrier H, the water is withdrawn from the pulp deposited on the
form. This latter being made in sections (here 4), as shewn, it is easily
removed, either immediately after the deposition of the pulp (in which
case another easily removable form is inserted to preserve the shape of
the box while it is being dried), or it may be removed after the box has
been dried in the drying stove.
The form carrier, and with it the form, or the circumference of same
only, may in some instances be made to expand, and by such expansion:.

page_text: excrt the necessary pressure for consolidating the pulp, the mould in that
case being made incontractible, the mode of operation being in fact
reversed. This answers tolerably well for rough work, but is not so good
as the outward pressure, because there is thereby produced a tendency to
separate the fibre of the material, and to split or weaken the box at the 5
edge or place of junction of the bottom and the circumference.
Figs. 6 and 7 are vertical sections showing such a form carrier
respectively when contracted and expanded. H is the carrier; H¹ the
upper part of same, which is made in three or more parts, that are
expanded and contracted by means of the cone K, which by dovetails or 1
other suitable means (not shewn here) is connected to the parts H².
The rim J of the form is formed with a flange, as shown, in order to
prevent the bottom of the box from being separated from its rim when
the box is removed or stripped from the form carrier. The flange of
the rim may be made as a continuous ring or not, or the rim may at 1
this place be formed with other equivalent projections for the said
purpose.
And having thus fully described and ascertained the nature of this
Invention, I declare that I claim as applied to machines constructed or
operating substantially as hercin set forth, and as set forth in the
Specification of the British Patent, dated 7th May, 1873, No. 1649,—
First. Cutting off the supply of pulp by automatically worked slide
or equivalent means, as set forth.
Second. Making the "mould" of india-rubber or other suitable elastic
or contractible material, as described and as shewn.
Third. The modes of contracting the "mould" and of expanding the
form carrier, as described and as shewn.
Fourth. Making the form flexible or clastic and perforated or
permeable, as set forth.
Fifth. Making the "form" of two parts, viz., the perforated or
permeable bottom, and the circumference as a perforated or permeable
thin collapsible ring, with or without flange, all substantially as set
forth.

page_text: Sixth. Making the "form" of three or more sections, substantially as
described and as shewn.
In witness whereof, I, the said Peter Mesick, have hereunto set my
hand and scal, this Thirteenth day of November, in the year of
our Lord One thousand eight hundred and seventy-four.
