Year: 1866

page_text: LETTERS PATENT to Thomas Vaughan Morgan, of Chelsea, in the
County of Middlesex, and Edwin Hyles, of Battersea, in the County
of Surrey, for the Invention of "IMPROVEMENTS IN APPARATUS FOR THE
MANUFACTURE OF CRUCIBLES AND OTHER HOLLOW ARTICLES FROM PLASTIC
MATERIALS"
Scaled the 11th June 1867, and dated the 15th December 1866.
PROVISIONAL SPECIFICATION left by the said Thomas Vaughan Morgan
and Edwin Hyles at the Office of the Commissioners of Patents, with
. their Petition, on the 15th December 1866.
We, THOMAS VAUGHAN MORGAN, of Chelsea, in the County of Middlesex,
and EDWIN HYLES, of Battersea, in the County of Surrey, do hereby declare
tho nature of the said Invention for "IMPROVEMENTS IN APPARATUS FOR THE
MANUFACTURE OF CRUCIBLES AND OTHER HOLLOW ARTICLES FROM PLASTIC
MATERIALS," to be as follows:-
Our Invention consists in fitting, as hereafter described, the former or
forming tool employed in apparatus for the manufacture of crucibles and other
hollow articles, so that in addition to being capable of an up-and-down

page_text: movement the former is free to be moved and adjusted horizontally as the
crucible or other article is being moulded, and according to the required size
or thickness of the crucible or other article, also in the employment as here-
after described of a lever to prevent all vibration or movement of the former
when at its final position in the crucible.
Our Invention is carried into effect as follows:-The former or forming
tool is fitted to a block free to be moved horizontally in a frame by means
of a horizontal threaded rod which takes into a corresponding female thread
in the block, the ends of this rod work in fixed nuts on the frame, and one
end is provided with a handle which is turned according as the former and
its block are required to moved. The frame before mentioned is free to
move up and down in slots formed in two uprights, and its weight is counter-
balanced. The bottom of the slots limit the distance to which the frame
with the former can be lowered. When a crucible is to be made the frame
is pulled down to cause the former to enter the plastic material, which is
placed in a mould on a revolving lathe or "jigger" as usual, and when the
former reaches the bottom of its course a catch on one of the uprights secures
the framing in position. The threaded rod is then turned to cause the former
to move horizontally, and spread the plastic material against the side of the
mould. Finally, the back end of a lever carried on the top of the frame and
free to move backward by means of a slot or otherwise is inserted into a hole
formed for the purpose and its forward end is pressed down by hand, so that
the lever bears forcibly upon the frame and prevents all vibration or move-
ment of the former. When the crucible is finished the handle is turned to
bring the former to the centre of the crucible, the lever is moved forward
out of its hole, the catch released, and the frame pushed up. The operation
is then repeated for the next crucible, and so on.
Our Invention further consists in the employment of a break to stop the
revolution of the lathe or jigger when the driving belt is moved from the
fast to the loose pulley of the lathe shaft. This break is preferably composed
of a horizontal bar hinged behind the apparatus, while one cnd extends to
the front of the apparatus near to the attendant. The bar carries a block,
and when the break is to be applied the attendant, by his foot or otherwise,
moves the bar on its hinge so as to cause the block to bear against a collar
or otlier revolving portion of the lathe.

by the said Thomas Vaughan Morgan and Edwin Hyles in the Great
Seal Patent Office on the 15th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
VAUGHAN MORGAN, of Chelsea, in the County of Middlesex, and EDWIN
HYLES, of Battersea, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-six, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Thomas Vaughan Morgan and Edwin Hyles, Her special licence that we, the
said Thomas Vaughan Morgan and Edwin Hyles, our executors, administrators,
and assigns, or such others as we, the said Thomas Vaughan Morgan and
Edwin Hyles, 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
APPARATUS FOR THE MANUFACTURE OF CRUCIBLES AND OTHER HOLLOW ARTICLES
PROM PLASTIC MATERIALS," upon the condition (amongst others) that we, the
said Thomas Vaughan Morgan and Edwin Hyles, or one of us, our executors or
administrators, by an instrument in writing under our, or one of 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 per-
formed, 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 we, the said Thomas Vaughan Morgan and Edwin
Hyles, 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 thereof; reference being had to the
Drawings hereunto annexed, that is to say :-
or
.. Our. Invention consists in fitting as herein-after described the "former"
forming tool employed in apparatus for the manufacture of crucibles and
other hollow articles, so that in addition to being capable of an up-and-down
movement, the former is free to be moved and adjusted horizontally as the
crucible or other article is being moulded, and according to the required size
or thickness of the crucible or other article; also in the employment as herc

page_text: after described of a lever to prevent all vibration or movement of the former
when at its final position in the crucible.
Our Invention is carried into effect as follows:-The former or forming
tool is fitted to a block free to be moved horizontally in a frame by means of
a horizontal threaded rod which takes into a corresponding female thread in
the block; the ends of this rod work in fixed nuts on the frame and one end
is provided with a handle which is turned according as the former and its
block are required to be moved. The frame before mentioned is free to move
up and down in slots formed in two uprights and its weight is counterbalanced.
The bottom of the slots limits the distance to which the frame with the
former can be lowered. When a crucible is to be made the frame is pulled
down to cause the former to enter the plastic material which is placed in a
mould on a revolving lathe or "jigger" as usual, and when the former
reaches the bottom of its course a catch on one of the uprights secures the
frame in position. The threaded rod is then turned to cause the former to
move horizontally and spread the plastic material against the side of the
mould. Finally the back end of a lever carried on the top of a frame and
free to move backward by means of a slot or otherwise is inserted into a hole
formed for the purpose, and its forward end is pressed down by hand, so that
the lever bears forcibly upon the frame and prevents all vibration or move-
ment of the former. When the crucible is finished the handle is turned to
bring the former to the centre of the crucible, the lever is moved forward out
of its hole, the catch released, and the frame raised up by a balance weight.
The operation is then repeated for the next crucible, and so on.
Our Invention further consists in the employment of a break to stop the
revolution of the lathe or jigger when the driving belt is moved from the fast
to the loose pulley of the lathe shaft. This break is preferably composed of a
horizontal bar hinged behind the apparatus, while one end extends to the
front of the apparatus near to the attendant. The bar carries a block, and
when the break is to be applied, the attendant, by his foot or otherwise, moves
the bar on its hinge so as to cause the block to bear against a collar or other
revolving portion of the lathe.
Figure 1 of the accompanying Drawings is a front elevation; Figure 2
a side elevation; and Figure 3 a section through the line A, A, of Figure 1
of an apparatus constructed according to our improvements.
a is the former or forming tool; it is fitted to a block b, which is as
before stated free to be moved horizontally in a frame c by means of a hori-
zontal threaded rod d, taking into a corresponding thread e in a nut b' in the
block b, the ends of the rod a work in fixed nuts f,f, on the frame c, and the
ๆ

page_text: right-hand end is provided with a handle g which is turned according as the
former a and block are required to be moved. The frame c is free to
move up and down in slots h, h, formed in two uprights i, j, and its weight is
counterbalanced by weights k, k, on the end of chains or cords 1; 1, passed
over pulleys m, m, and connected to the frame c. n is a catch on the upright
jto secure the frame c in position when the former a reaches its lowest
position, o is the mould into which the plastic material is fed; this mould is
carried on an ordinary lathe or jigger p, to which rotary motion is imparted
as, usual. When the frame c is caught by the catch n, and the mould is
caused to rotate, the threaded rod d is turned by its handle à so as to cause
the former a to move horizontally and spread the plastic material against the
side of the mould o; and when it has been moved to the required distance,
which is regulated by a scale on the frame c, the back end of a lever q carried
on the top of the frame cand free to move backward by means of a slot r is
inserted into a holes formed in an upright t, and its forward end is then
pressed down by the attendant so that this lever bears forcibly upon the frame o
and prevents vibration or movement of the former a. When the crucible is
finished the handle g is turned to bring the former a to the centre of the
crucible, the lever q is moved forward out of its hole s, the catch n is released,
the frame c is raised up, and the mould is removed in the ordinary manner;
all being then ready for the next operation. " is a horizontal bar under the
platform and hinged at w, while its front end extends to the front of the
apparatus. is a block on the bar u, and y is a collar on the lathe shaft.
When it is required to stop the revolution of the lathe the attendant moves
the bar u on its hinge wo, so as to bring the block against the collar y. z is
a horizontal bar or guide for the bar u.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we claim as our
"Improvements in Apparatus for the Manufacture of Crucibles and other
Hollow Articles from Plastic Materials,"-
First. Fitting the former or forming tool of such apparatus, so that in
addition to being capable of being moved up and down it is free to be moved
and adjusted horizontally as the article is being moulded, and according to the
size or thickness of the article, substantially as herein-before described and
represented in the accompanying Drawings.
Second. The employment in such apparatus of a lever substantially as
herein-before described and represented in the accompanying Drawings, to
prevent all vibration or movement of the former or tool when at its final
position in the crucible or other article.

page_text: Third. The employment in such apparatus of a break, substantially as
herein-before described and represented in the accompanying Drawings, to
stop the revolution of the lathe or jigger when the driving belt is moved from
the fast to the loose pulley. of the lathe shaft.
In witness whereof, I, the said Thomas Vaughan Morgan, for myself
and on behalf of the said Edwin Hyles, have hereunto set my hand
and seal, this Thirteenth day of June, One thousand eight hundred
and sixty-seven.
