PROVISIONAL SPECIFICATION left by the said George Perry and
Edwin Perry at the Office of the Commissioners of Patents, with
their Petition, on the 3rd December 1875.
We, GEORGE PERRY and EDWIN PERRY, of Gateshead, in the
County of Durham, Engineers, do hereby declare the nature of the said
Invention for "AN IMPROVED PRESS FOR MOULDING GLASS, AND A NEW OR
IMPROVED APPARATUS OR 'GATHERER' POR SERVING THE SAME,'
" to be as
follows:-

page_text: Hitherto the means employed to meet the requirements that have
unexpectedly arisen since the introduction of the steam press into the
glass trade by the said George Perry, as specified in his Specification,
No. 3216, 1872, have been either costly or incomplete, inasmuch as no
provisions have as yet been made for the greater speed in which articles
are manufactured, necessitating an extra number of gatherers who in
their haste to feed the machine often obstruct each other. To obviate
these defects we construct a press similar in many respects to the one
described in the Specification above named, but in this instance the
travelling bed plate does not revolve, an intermittent to-and-fro motion
being substituted therefor. On this bed plate is fixed a duplicate of the
desired number of moulds, one set only at a time being filled with
metal. This allows the other set of moulds, which we may suppose had
previously been worked, to grow cool and act as a reserve when those in
use shall in their turn become too hot to be profitably employed. A
block at the rear end of the press is by means of rods and levers made
to obstruct to the required extent the path travelled by the bed plate;
this necessarily shortens the distance travelled and brings the second set
of moulds under the press, the moulds being first filled by the gatherers,
to be acted upon by the moulders secured to the plunger. This done
the plunger rises and the bed plate returned by a cam acting upon a
lever to the fore part of the press, where it is detained by a catch or
other approved means to allow the moulded articles being removed and
the moulds refilled by an apparatus herein-after specified. Upon this
second set of moulds becoming heated the block is removed and the bed
plate travels back the full distance, bringing the now cool set under the
plunger.
The foregoing are the simple and efficacious means I adopt to cool
the moulds when they have become heated in consequence of frequent
filling.
To assist the man in removing expeditiously the moulded articles
from the moulds we cause the false bottoms of the moulds to be acted
upon and forced upward. This might be done by the long arm of a
lever becoming depressed on its arrival at the fore end of the machine.
The working parts of this press are too well known to require a
detailed description, everything working in unison with the plunger.
In working steam presses for moulding glass it has been found that

page_text: unless all the moulds be simultaneously filled the metal in the mould first
served becomes set and difficult to work. We have therefore introduced
a novel and useful apparatus for filling all the moulds except the
reserved set at once. The apparatus may be thus described presuming
thereto be three moulds to be filled together. Three spindles supported
in a light frame and running parallel with one another have each a cog
wheel gearing into its neighbour, so when one is turned they all turn.
One end of the spindles project from the side of the frame and has a
socket wherein is fixed the gathering iron, the other end works in a
bearing in the opposite side of the frame. The centre spindle however
after running through a hollow handle formed for the workman to hold
terminates in a winch handle, to which rotary motion can be given by
the operator. This motion by means of the aforesaid cog wheels is
conveyed to the spindle on either side, communicating to the gathering
irons the peculiar motion required by that tool.
To charge the apparatus with metal the operator holding the apparatus
in one hand turns the winch handle and dips the three gathering irons
into the metal. The metal is at once gathered up and conveyed from
the furnace to the press and held over the moulds to be filled, each
gathering iron being at the same distance from centre to centre as are
the moulds. Consequently when the operator ceases turning the winch
handle the metal drops from each gathering iron into their respective
mould.

"
NOW KNOW YE, that I, the said Edwin Perry, on behalf of myself
and of the said George Perry, do hereby declare the nature of our said
Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following state-
ment in writing, reference being had 'to the accompanying Drawings,
and to the letters and figures marked thereon (that is to say) :—
The main object of our Invention is to simplify, improve, and increase
the productive power or economy of steam presses used in moulding
glass.
Hitherto the means employed to meet the requirements that have
unexpectedly arisen since the introduction of the steam press into the
glass trade by the said George Perry, as specified in his Specification
No. 3216, 1872, have been either costly or incomplete, inasmuch as no
provisions have, as yet, been made for the greater speed in which
articles are manufactured, necessitating an extra number of gatherers,
who in their haste to feed the machine often obstruct each other. To
obviate these defects we construct a press similar in some respects to the
one described in the Specification above named; but in this instance
the moulds do not revolve, an intermittent to-and-fro motion of the
travelling bed plate being substituted therefor. On this travelling bed
plate is fixed a duplicate of the desired number of moulds, one set only

page_text: at a time being filled with metal. This allows the other set of moulds,
which we may suppose had previously been worked, to grow cool and
act as a reserve to be employed when those in use shall in their turn
become too hot to be profitably engaged. A block at the rear end of the
press is by means of rods and levers made to obstruct at the proper time
and to the required extent the path travelled by the bed plate. This
necessarily shortens the distance travelled by the said bed plate, and
brings the second or reserve set of moulds, the said moulds being first
filled by the gatherers, under the plungers to be acted upon by the
descent of the cross head of the press; this done the plungers rise, and
the bed plate returned by means of a cam to the fore part of the press,
where it is detained by a catch or other approved means until the
moulded articles have been removed, and the moulds refilled with metal
by an apparatus herein-after described.
We will now proceed to describe more fully the construction and
operation of our improved press, reference being had to the accompanying
Drawings, and to the letters and figures marked thereon.
Figure 1 is a side view of our machine adapted to press three moulds
at once, although any reasonable number with a corresponding number
of plungers may be applied; Figure 2 is a front view of the same on
line C, D, Figure 5, to show the means employed to actuate and control
the bed plate on which the desired number of moulds and a duplicate
thereof are fixed; Figure 3 is a side view on line A, B, Figure 5,
shewing the manner of cutting off the supply of steam to the cylinder
of the steam engine working the said press, and again setting the same
in action; Figure 4 is a sectional plan with the bed plate and other
parts removed; and Figure 5 a top plan of the complete machine.
In Figure 6 is shown the method of raising the false bottoms of the
moulds, and Figure 7 is a view of the under side of the travelling bed
plate.
In all these Figures a', a", a", are the three moulds; and 6', 6', 6''',
the second or reserve set of moulds; c', c", c", are the plungers, each
provided as usual with a ring and an adjustable spring, and secured to
the plate v, which is capable by means of the hand wheels or nuts o*, *,
of being adjusted along the length of the plunger spindle or screw C;
D is the block, which is precisely the width as the distance is between

page_text: the centres of the two transverse rows of moulds; consequently, when, by
turning the handle d, see Figure 2, in the direction shown by the arrow,
the block is placed across the end of the path travelled by the bed
plate A, the journey of the said bed plate is shortened to that extent,
and the second or reserve set of moulds brought thereby under the
plungers to be acted upon by the descent of the cross head, which is
accomplished in the manner following:-The operator having filled the
moulds with the proper quantity of metal pulls over the handle i, see
Figure 3, and brings thereby the toggle jointed bar into the position
shewn by dotted lines. This act accomplishes two distinct purposes, —
First. By lifting the outer arm of the bell-crank lever r, see Figures 2
and 3 (the inner arm of which is attached to the spring catch S) the
bed plate A is set free to be acted upon by the weight T, which
descending causes, by means of a chain passing over a pulley, the said
bed plate to travel in a horizontal direction and carry either set of
moulds under the plungers according as the block D is raised or
lowered.
Second. The vertical rod f, being now unsupported by the toggle
jointed bar, and so made as to spring to the position shown in dotted
lines on the Drawing, takes with it the rod k, which by any suitable
arrangement of levers opens the steam cock / supplying with steam the
cylinder of the engine working the press and setting the same in
action.
Motion being now communicated by any suitable gearing to the cog
wheel h keyed on the main shaft h* of the press it is conveyed to the
cross head by means of cranks and connecting rods, as shewn on the
Drawing in Figure 2. The plungers will now descend and press the
moulds directly under it. On the shaft h* is also keyed a cam U, see
Figures 1, 2, and 4, which begins to engage with the projecting piece U*,
bolted to the sliding bar M, only when the plungers c¹, c¹, c¹¹¹, are free
from the moulds. In that case the sliding bar acting upon one arm of
the horizontal lever N, the other arm of which has a slot for the pino of
the bed plate A to work, removes the said bed plate from under the
plungers to the fore part of the press, in which position it is held by the
spring catch 8, see Figure 4, until such time as the operator may set it
and the machine again in action by pulling over the handle i, as before
explained.

page_text: The bed plate is provided with means by which the moulded articles
may be raised or started from their beds ready for the operator to remove.
This is performed by the ends of the levers q, q*, see Figures 5 and 7,
being driven, by the bed plate arriving at the fore part of the press,
under and depressed by the catches p, p*. To forward this object the
ends of the levers are wedge shaped. By referring to the Drawing it
will readily be seen that the false bottoms of the mould would be raised
by the plates q¹, q¹. The moulded articles being now removed, and the
cross head having nearly reached the top of its stroke, meets with the
adjustable catch g, and carrying it upward raises the vertical rod f. In
raising this rod (which is now kept in a straight line by the toggle
jointed bar ) two objects are attained, first, the levers q, q*, are released
from the catches p, p*, letting the false bottoms of the moulds drop
down ready to receive the metal. This is accomplished by the bell-
crank lever p¹, see Figure 3, with an adjustable arm engaging with the
aforesaid vertical rod, the other arm connected by a bent rod to a similar
but horizontal lever p¹ at the end of the bolt from which the
catches p, p, project, see Figure 6. The action of the same will be
easily understood by referring to the Drawing, Figures 3, 5, and 6. The
second object is to turn off the supply of steam, thereby stopping the
press until the moulds are prepared with fresh metal. This is executed
by the lower end of the vertical rod f, which is formed as shewn in
Figures 3 and 9, and acting as an inclined plane, which meeting in its
upward progress with the end of the rod k exerts a pressure thereon,
and by any suitable arrangement of levers turns off the steam cock 7,
leaving the cross head at the top of its stroke. This position of the
cross head may be further induced by the cog wheel h being suitably
weighted.
It will be observed that the guides a*, a*, Figure 2, have been partly
removed from Figures 1 and 2, to render more clear the pin o and the
false bottoms of the moulds resting upon the plates q¹, q", and that the
action of the press is entirely under the control of the operator, and that
it is impossible for the travelling bed plate or the plunger to start on
their journey until every working part of the press is set in operation by
pulling over the handle i. By this means all fear of the moulds and
plungers coming in contact is avoided, every portion of the press being
made to work in harmony.
In serving a press having several moulds it is found that the metal

page_text: in the mould first filled becomes set before it arrives under the plunger;
to remedy this evil we employ a novel and useful apparatus, shown in
Figures 8, for filling at once all the moulds except the reserve set. It
consists of a light frame a, a, supporting the same number of
spindles b, b, as there are moulds to be simultaneously filled. The
spindles have keyed on each a cog wheel c, c, gearing into its neighbour,
so when one is turned they all turn. One end of the spindles project
from the said frame and has a socket, wherein is fixed by a set screw the
gathering iron; the other end of the spindles work in a bearing in the
opposite side of the frame, one of the spindles, however, after running
through a hollow handle formed for the workman to hold, terminates in
a winch handle to which rotary motion can be given by the workman.
This motion, by means of the aforesaid cog wheels, is conveyed to each
spindle communicating to the gathering irons the peculiar motion
required by that tool. To charge the moulds with metal the workman
holding the apparatus in one hand turns the winch handle and dips the
gathering irons into the metal. The metal is at once gathered up and
carried from the furnace to the press and held over the moulds to be
filled, each gathering iron being at the same distance from centre to
centre as are the moulds, consequently when the workman ceases
turning the winch handle the metal drops from the gathering irons into
their respective moulds.
If from the number of gathering irons the apparatus should become
too cumbersome for the workman to handle, an overhead travelling gear
is attached to the lugs or bolts e, e, and the apparatus slung from
furnace to press.
Figures 10 and 11 are a modification of our Invention suitable to
those circumstances where steam power is inapplicable. The main
shaft in that case is made longer to receive the tilting lever L (which
may (as is usual) or may not have a balance weight). The cranks C
and the connecting rods R are formed, as shown on the Drawings, to meet
the requirements of the machine. The cam U and the projecting
pin U* are formed, as shown. When hand power is used the spring
catch 8, see Figure 4, is fastened back by tightening up the screw there
shown; and the adjustable catch g, Figure 3, is raised by the nuts above
reach of the cross head.
Having now particularly described and ascertained the nature of our
'said Invention, and in what manner the same is to be or may be

page_text: tion secured to us by Letters Patent, as aforesaid, the general arrange-
ment and operation of the glass press and gatherer, as herein set forth
and illustrated on the accompanying Drawings or any mere modifi-
cations thereof.
In witness whereof, I, the said Edwin Perry, have hereunto set
my hand and seal, this Second day of June, in the year of our
Lord One thousand eight hundred and seventy-six.
