PROVISIONAL SPECIFICATION left by the said Hiram Hutchinson at the.
Office of the Commissioners of Patents, with his Petition, on the 21st.
September 1863.
I, HIRAM HUTCHINSON, of No. 26, Rue Notre Dame des Victoires, Paris,
Manufacturer of India-rubber, do hereby declare the nature of the Invention.
for "IMPROVEMENTS IN MACHINERY FOR MANUFACTURING MOULDED ARTICLES OF
INDIA-RUBBER," to be as follows:-
In constructing machinery for manufacturing moulded articles of india-.
rubber according to this Invention the machine is composed of a bed plate-
upon which the outer half of the mould employed is fixed; this half of the
mould is open at the top; the follower (or portion of the mould that passes.
into the interior of the outer half of the mould through its open top) can be
moved up or down, and is kept in its correct position by guides carried by
standards that project upwards from the bed plate; the top of the follower is
connected to the lower end of a screw in such manner that the screw can turn
round freely; the screw at its upper end passes through the hollow axis of a

page_text: toothed wheel to which rotary motion can be given by means of a toothed wheel
gearing with it; the axis of this wheel receives motion from an axis driven
by straps or bands from the engine; this axis can be driven in either direction
by having two fast pullies upon it, one of which can be driven by a crossed,
and the other by an uncrossed band. On the interior of the hollow axis
through which the screw passes is a key which is received into a groove that
runs from end to end of the screw, so that when the hollow axis is caused to
rotate in either direction the screw turns with it; the screw passes through a
fixed nut carried by the framing, so that when the screw is caused to revolve
it will also be caused either to move upwards or downwards and will carry the
follower with it. In order that the screw may be stopped from revolving as
soon as the follower has arrived at its highest or lowest position a disc or
projection carried on the upper end of the screw is, as soon as the follower bas
arrived at either end of its course, caused to come against and lift a lever
catch and so allow a fork that embraces the band that was before giving
motion to the screw to be moved by a weight in such manner as to shift the
band from the fast pulley to the loose pulley, thus the screw cannot be moved
too far in either direction. Both the outer portion of the mould and also the
follower, are formed with a hollow chamber that passes all round them, into
which superheated steam can be introduced. The compound of india-rubber
that is to be moulded is placed in the outer portion of the mould, and the
screw is then caused to turn in such manner as to force down the follower
into it, and the two parts of the mould are caused to go accurately together
by a ring on one part entering a recess formed to receive it in the other part.
If the india-rubber compound is to be vulcanized in the mould the follower
must remain down in this position during the time requisite for completing
the vulcanizing process, and as soon as this is effected motion is again given
to the screw, but in the contrary direction, so as to raise the follower; the
moulded article can then be raised out of the mould by a loose plate at its
-bottom being pushed upwards by means of a pin that is forced upwards
through a hole in the bottom of the mould by a treadle; the mould is then
ready to be again used. In place of the moulded article remaining sufficiently
long in the mould for the vulcanizing process to be completed the moulded
article, may be withdrawn from the mould without being vulcanized. The
machine above described is applicable for the manufacture of hollow articles
of india-rubber, such as boxes, trunks, pots, pails, and other like articles.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HIRAM
HUTCHINSON, of No. 26, Rue Notre Dame des Victoires, Paris, Manufacturer
of India-rubber, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of September, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Hiram Hutchinson, Her special licence that I, the said Hiram
Hutchinson, my executors, administrators, and assigns, or such others as I, the
said Hiram Hutchinson, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after 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 MACHINERY FOR MANUFACTURING MOULDED ARTICLES OF INDIA-RUBBER," a com-
munication to me from abroad by John Green, a person resident at New York,
in the United States of America, upon the condition (amongst others) that I, the
said Hiram Hutchinson, 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 sail Letters Patent.
NOW KNOW YE, that I, the said Hiram Hutchinson, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
In constructing machinery for manufacturing moulded articles of india-
rubber according to this Invention, the machine which is shown in the
annexed Drawings is composed of a bed plate a, upon which the outer half
b of the mould employed is fixed, this half of the mould is open at the top.
The follower (or portion 6' of the mould that passes into the interior of the
outer half of the mould through its open top) can be moved up or down, and
is kept in its correct position by guides carried by standards c, that project
upwards from the bed plate; the top of the follower is connected to the lower
.

page_text: end of a screw d in such manner that the screw can turn round freely; the
screw d at its upper end passes through the hollow axis e of a toothed wheel
f, to which rotary motion can be given by means of a toothed wheel g gearing
with it; the axis of this wheel receives motion from an axis h, driven by
straps or bands from the engine; this axis can be driven in either direction
by having two fast pulleys upon it, one of which can be driven by a crossed
and the other by an uncrossed band. On the interior of the hollow axis e
through which the screw d passes is a key which is received into a groove
that runs from end to end of the screw, so that when the hollow axis e is
caused to rotate in either direction the screw d turns with it; the screw passes
through a fixed nut i, carried by the framing, so that when the screw is
caused to revolve it will also be caused either to move upwards or downwards
and will carry the follower with it. In order that the screw d may be
stopped from revolving as soon as the follower has arrived at its highest or
lowest position, a disc or projection d', carried on the upper end of the screw,
is as soon as the follower has arrived at either end of its course caused to lift
one or other of the lever catches k, and so allow a fork that embraces the
band that was before giving motion to the screw to be moved by one or other
of the weights m in such manner as to shift the band from the fast pulley to
the loose pulley, thus the screw d cannot be moved too far in either direction.
The outer portion of the mould and also the follower bare formed with
hollow chambers & passing all round them, into which superheated steam can
be introduced. The compound of india-rubber that is to be moulded is
placed in the outer portion 6 of the mould, and the screw d is then caused to
turn in such manner as to force down the follower b¹ into it, and the two
parts of the mould are caused to go accurately together by a ring 6x on
one part entering a recess formed to receive it in the other part; if the india-
rubber compound is to be vulcanized in the mould the follower must remain
down in this position during the time requisite for completing the vul-
canizing process, and as soon as this is effected motion is again given to the
screw but in the contrary direction, so as to raise the follower 61; the
moulded article can then be raised out of the mould by a loose plate n at its
bottom, being pushed upwards by means of a pin o that is forced upwards
through a hole in the bottom of the mould by a treadle, the mould is then
ready to be again used. In place of the moulded article remaining sufficiently
long in the mould for the vulcanizing process to be completed, the moulded
article may be withdrawn from the mould without being vulcanized. The
machine above described is applicable for the manufacture of hollow articles
of india-rubber, such as boxes, trunks, pots, pails, and other like articles.

page_text: The form of the mould is of course varied according to the form of the article
it is desired to mould.
In witness whereof, I, the said Hiram Hutchinson, have hereunto set
my hand and seal, this Fourteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-four.
