IMPROVEMENTS IN THE CON- STRUCTION OR ARRANGEMENT OF MACHINERY FOR FORMING OR SHAPING PROVISIONAL SPECIFICATION
Year: 1875

page_text: LETTERS PATENT to Thomas Vaughan Morgan, of the Battersea
Works, Battersea, in the County of Surrey, Plumbago Crucible
Manufacturer, for the Invention of "IMPROVEMENTS IN THE CON-
STRUCTION OR ARRANGEMENT OF MACHINERY FOR FORMING OR SHAPING
PROVISIONAL SPECIFICATION left by the said Thomas Vaughan
Morgan at the Office of the Commissioners of Patents, with his
Petition, on the 30th March 1875.
I, THOMAS VAUGHAN MORGAN, of the Battersea Works, Battersea,
in the County of Surrey, Plumbago Crucible Manufacturer, do hereby
declare the nature of the said Invention for "IMPROVMENTS IN THE CON-
STRUCTION OR ARRANGEMENT OF MACHINERY FOR FORMING OR SHAPING CRUCIBLES
AND OTHER LIKE ARTICLES FROM PLASTIC MATERIAL," to be as follows:-
This Invention relates to improvements in the construction or
arrangement of machinery for forming or shaping crucibles and other
like articles from plastic material, the objects being,--

page_text: Making ICIDICS O TIRO arVICIOS ULICULL ԵՂԵՍՍԵ
by machinery.
3. Better finish and more compactness of the articles.
And, 4. Expedition in the manufacture.
The machine consists of two standards or uprights upon suitable
foundations, and with a cross stay or tie bar at top, above which a shaft
is mounted, the shaft being actuated from an overhead motion. The
shaft is arranged for carrying bevil wheels, which actuate other wheels
fixed upon the upper ends of threaded rods arranged in adjustable step
bearings projecting from the standards.
The threaded rods carry a traveller frame, the ends of which slide
between two checks of the uprights to guide the traveller frame in its
up-and-down movements. This traveller frame carries a block within
it, the block being adjustable under the action of a threaded rod, the
outer end of which has a bevil wheel upon it in gear with another bevil
wheel feathered upon a vertical shaft, the turning of which from an
underneath clutch motion determines the distance or position at which
the block can be set. The block carries the tool or 'former," and this
is keyed in or otherwise fixed in the block, so that it can be removed
and another tool or former fixed in its place.
"
Under the central part of the machine frame I arrange a cup or
mould receiver, the cup being upon a vertical shaft, by which it can be
rotated from gearing below, this being actuated direct from clutch
gearing in connection with fast and loose pullies.
I fit the starting and reversing levers in proximity to the workman,
so that he has complete control over the working of the machine, and
of the formation or thickness of the wall of the crucible or other hollow
article of plastic body, that is, within the mould contained in the cup
before referred to.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Vaughan Morgan in the Great Seal
Patent Office on the 29th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
VAUGHAN MORGAN, of the Battersea Works, Battersea, in the County
of Surrey, Plumbago Crucible Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of March, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Thomas Vaughan Morgan, Her special
licence that I, the said Thomas Vaughan Morgan, my executors, admi-
nistrators, and assigns, or such others as I, the said Thomas Vaughan
Morgan, 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 CONSTRUCTION OR ARRANGEMENT OF MACHINERY FOR
FORMING OR SHAPING CRUCIBLES AND OTHER LIKE ARTICLES FROM PLASTIC
MATERIAL," upon the condition (amongst others) that I, the said Thomas
Vaughan Morgan, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Thomas Vaughan Morgan, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
This Invention relates to improvements in the construction or
arrangement of machinery for forming or shaping crucibles and other
like articles from plastic material, the objects being,-
1stly. Reduction of hand labour.

page_text: 3rdly. Better finish and more compactness of the articles.
And, 4thly. Expedition in the manufacture.
The machine consists of two standards or uprights A, A, upon
suitable foundations B, and with a cross stay or tie bar O at top, above
which a shaft D is mounted, the shaft being actuated from an overhead
motion; the shaft is arranged for carrying bevil wheels E, E, which
actuate other wheels F, F, fixed upon the upper ends of threaded rods
G, G, arranged in adjustable step bearings H, H, projecting from the
standards A, A.
The threaded rods G, G, carry a traveller frame I, the ends of which
slide between two cheeks or in a slot J of the uprights to guide the
traveller frame in its up and down movement. The traveller frame I
carries a block K within it, the block being adjustable under the action
of a threaded rod L, the outer end of which has a bevil wheel M upon
it in gear with another bevil wheel N feathered upon a vertical shaft P,
the turning of which from clutch mechanism Q determines the distance
or position at which the block K can be set. The block carries the tool
or "former" R, and this is keyed in or otherwise fixed in the block so
that it can be removed and another tool or former fixed in its place
when desired. At the central part of the machine I arrange a cup or
mould receiver S, the cup being upon a vertical shaft T, by which it
can be rotated by bevil gearing U from a fast pulley V at the side, a
loose pulley being provided for shifting the strap on to by a motion of
the band lever X.
I fit the starting and reversing levers X, Y, in proximity to the
workman who stands upon the platform Z, there being a clearance all
round the cup to enable him to have perfect command over the working
of the plastic body placed into the mould, and from which the article
is to be made. The vertical threaded rods G, G, are capable of rotation
in either direction to lower the traveller L for the downward action of
the former upon the plastic body within the mould, or to raise the
former from the mould when desired, the outward action of the former
against the plastic body within the mould being by means of the
threaded rod L from its gearing M, N. a is a lever for actuating the
break b, the band of which partly encircles the break wheel c and effects

page_text: the stoppage of the "former" or tool R in its side travel at any given
position to suit the thickness of the wall of the article being made
within the cup.
The bevil wheels E, E, are on a sleeve d of the shaft D, and the sleeve
has an end-on motion under the action of a lever e to put the bevil
wheels E, E, in gear or out of gear with the wheels F, F; f is the
hand lever for actuating or directing the rotation of the bevil wheels g, g,
of the clutch mechanism Q.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim,―
The construction or arrangement of machinery for forming or shaping
crucibles and similar articles from plastic material, as set forth and
shown in the accompanying Drawings.
Secondly. I claim the employment of appliances as shown in the
annexed Drawings, or any modification thereof, by which the different
actions can be effected in machines for producing crucibles or other
similar articles from plastic material, as set forth.
In witness whereof, I, the said Thomas Vaughan Morgan, have
hereunto set my hand and seal, this Twenty-fifth day of
September, One thousand eight hundred and seventy-five.
THỨ, VAUGHAN MORGAN. (L.S.)
