Year: 1872

page_text: LETTERS PATENT to George Perry, of Gateshead, in the County of
Durham, Engineer, for the Invention of "IMPROVEMENTS IN PRESSES,
MADE DODECATTY ADAPTED TO THASH TRED IN MOULDING GT100"
Sealed the 12th April 1873, and dated the 30th October 1872.
PROVISIONAL SPECIFICATION left by the said George Perry at the
Office of the Commissioners of Patents, with his Petition, on the
30th October 1872.
I, GEORGE PERRY, of Gateshead, in the County of Durham, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
PRESSES, MORE ESPECIALLY ADAPTED TO THOSE USED IN MOULDING GLASS," to be as
follows, that is to say :-
My Invention relates to certain improvements in presses more
especially employed in the manufacture of moulded glass, such presses
may however be used for certain descriptions of pottery or metal
wares.
By the improved arrangement and combination of the mechanical
parts of the press, as herein-after described, it may be worked either
by manual power as in the ordinary way, or by steam power as desired,
the same press being applicable for both.

page_text: The carriage or bed is formed with the usual tram or guide way,
upon which the travelling bed plates carrying the moulds are advanced
up to or withdrawn from the operation of the press; upon an axis,
on either side of the carriage are also secured the ordinary vertical
crank arms, worked by the usual tilting lever and connected at their
upper ends to an improved cross beam, which is secured centrally to
an adjustable vertical screw connected with the plunger of the press,
and both being contained in a casting to which is attached by brackets
or as one piece a vertical slide working in a suitable groove formed in
the back head of the press; it follows that when the tilting lever is
worked the action of the side crank arms and cross beam will cause
the slide and with it the plunger to work simultaneously and to rise
or fall with a steady action and without oscillation or jarring of the
plunger, whilst there will be but little wear or strain upon the working
parts.
The plunger may be adjusted to suit varying sizes of moulds by
means of the adjustable screw having upon its upper end a wheel and
handle, and to keep the cross beam rigidly in place when the plunger
is adjusted I screw a nut upon the back face of the cross beam on
the connecting pin passing through the cross beam to the adjustable
screw.
The improved portions for working the press by steam power consist
of a forward arm formed as part of the casting and slide before referred
to, in which works a vertical plunger capable of turning on its axis and
carrying a foot plate having one, two, or more moulders for descending
into corresponding moulds upon a travelling bed plate; this travelling
bed I arrange with a suitable number of moulds on a circular revolving
plate, so that a series of articles may be moulded at one operation
instead of singly as in the ordinary manner..
The steam power is applied by means of an eccentric and crank
attached to the slide before described, and actuated by means of suitable
driving gear.
In using steam power with the press the side arms or cranks and the
tilting lever required for the manual power are dispensed with and can
readily be detached.
The application of steam power to the description of press specified
effects a great saving of manual labor and also admits of the production

page_text: of the articles in multiple numbers in one operation instead of singly
by the usual method.

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Perry in the Great Seal Patent Office on
the 29th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME I, GEORGE
PERRY, of Gateshead, in the County of Durham, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of October, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Perry, Her special license, that I,
the said George Perry, my executors, administrators, and assigns, or such
others as I, the said George Perry, 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 PRESSES, MORE
ESPECIALLY ADAPTED TO THOSE USED IN MOULDING GLASS," upon the condition
(amongst others) that I, the said George Perry, 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 George Perry, 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 (that is to say) :-
My Invention relates to certain improvements in presses more
especially employed in the manufacture of moulded glass, such presses

page_text: may however be used for certain descriptions of pottery or metal
wares.
By the improved arrangement and combination of the mechanical
parts of the press, as herein-after described, it may be worked either by
manual power, as in the ordinary way, or by steam power, as desired,
the same press being applicable for both.
I will now proceed to describe my Invention more fully in detail, by
aid of the accompanying Drawings, reference being had to the letters
and figures marked thereupon.
Figure 1 is a side elevation of my improved press when arranged for
moulding glass by manual power; Figure 2 shewing in front elevation
a portion of the head of such press.
Figures 3 and 4 shew in front and side elevation my improved
press when altered or adapted for moulding glass by steam power.
Referring to Figures 1 and 2 (a) is the carriage or bed formed with
the usual tram or guide way (6) upon which the travelling bed plate (c),
Figure 1, carrying the mould (d) is advanced up to or withdrawn from
the operation of the press; upon an axis (e) on either side of the
carriage are also secured the ordinary vertical crank arms (f) worked
by the usual tilting lever (g) and connected at their upper ends to an
improved cross beam (h), shewn more clearly in Figure 2, which is
secured centrally to an adjustable vertical screw not shewn connected
with the plunger (i) of the press, and both being contained in a
casting (k), to which is attached by brackets or as one piece a vertical
slide (2) working in a suitable guide or groove (m) formed in the
head (n) of the press; it follows that when the tilting lever (q) is worked
the action of the side crank arms (✓) and cross beam (h) will cause the
slide (1), and with it the plunger to work simultaneously and to rise or
fall with a steady action, and without oscillation or jarring of the
plunger and die whilst there will be but little wear or strain upon the
working parts.
The plunger (i) may be adjusted to suit varying sizes or depths of
moulds by means of the adjustable screw having upon its upper end a
wheel and handle (0), and to keep the cross beam (h) rigidly in place
when the plunger (i) is adjusted I screw a nut (p) upon the back of
the cross beam (h) on the connecting pin passing through the cross beam
to the adjustable screw.

page_text: The improved parts to adapt the press for working by steam power
are shewn in Figures 3, 4, and 5, and they consist of a forward arm (r)
formed as part of the casting (k) before referred to; in the forward
arm (r) works a vertical plunger (s) capable of turning on its vertical
axis, and carrying a removeable foot plate (t), having one, two, or more
moulders (u) for descending into corresponding moulds (v) upon the
travelling bed (10), shewn in plan, Figure 5. This travelling bed (w) I
arrange with a suitable number of moulds (v) upon a circular revolving
plate (x) with means for accurate adjustment, by this arrangement
a series of articles may be moulded by one operation of the press
instead of being moulded singly as in the ordinary manner.
The steam power is applied by means of an eccentric and crank (y)
attached to the slide (1) by a pin working in a slot in the head (n) of
In using steam power
the press and actuated by suitable driving gear.
with the press the side arms or cranks (f) are disconnected from the
cross beam (h), and as shewn in Figures 3 and 4 the tilting lever (g) is
also dispensed with and may or may not be detached from the press as
desired.
The remainder of the mechanical parts of the press shewn in the
Drawings will be readily understood and require no further description.
Having thus described the object and nature of my said Invention,
and in what manner the same is to be carried into effect, I claim,
without limiting myself to these precise details, the several improve-
ments in presses, more especially adapted to those used in moulding
glass, substantially in manner as herein more fully set forth and
specified.
In witness whereof, I, the said George Perry, have hereunto set my
hand and seal, this 23rd day of April, in the year of our Lord
One thousand eight hundred and seventy-three..
