A New or Improved Machine for Releasing or Forcing Glass
Stoppers or other similar Pressed Glass Articles from their
Moulds.
We SAM REDFEARN of Old Mill Glass Works Barnsley in the County of York
Glass Bottle Manufacturer and WILLIAM HENRY MARSHALL of 42 Harbro Hills
Barnsley in the County aforesaid Glass Stopper Maker do hereby declare the nature
of this invention to be as follows:-
Our invention relates to means for forcing or releasing glass or other similar pressed
glass articles from the moulds wherein they have been pressed and the object thereof
is to release the whole of the pressed stoppers or other pressed glass articles so that
the same are simultaneously forced from the mould plate wherein they have been
pressed we obtain this by using a new or improved machine constructed in the
following manner and worked as hereinafter described.
On a pair of legs or a suitable frame or bed we fix or arrange a table having a
square or other suitable hole, along the sides of which is a lip or flange. On the said
table and at the back part thereof we secure a fixing or standard which is made with
a vertical bush or bearing arranged at a suitable elevation immediately above the
centre portion of the hole in the table, and at the top of this fixing or standard is
arranged a horizontal bearing or bush which carries a horizontal shaft extending there-
through. At the back of said horizontal bush and secured to the horizontal shaft is
keyed or otherwise secured a hand, fly, or other similar wheel which is suitably
weighted or balanced and at the front part of said horizontal bearing or bush is
secured or keyed to the same shaft a crank or disc having a pin arranged in a slot or
groove and capable of being regulated by means of a screw so as to alter or vary the
stroke as will be well understood.
A suitable vertical shaft works through the hereinbefore described vertical bush or
bearing and the top portion of said shaft is hinged to a suitable connecting rod which
connects to the pin of the crank or disc.
At the bottom of the vertical shaft is fixed a flat plate immediately beneath and
attached to which is another similar flat plate having any suitable number of projec-
tions or pins attached or fixed to and extending below it and which are of a suitable
size and correspond in position and number to the moulds formed in the mould
plate.
The mould plates fits or rests on the flange formed around the hole in the table, and
a suitable regulator is fixed on the table at the back of the hole so that the mould
plate can be placed in the required position for each pin to be directly over each
mould.
Underneath the table and directly below the hole therein is arranged and fixed a
suitable hopper having a sliding or other similar door at its lower portion beneath
which and secured to the legs or frame are suitable rests or supports for supporting
the taker's in shovel or box.
On one side of the table or at the top part thereof near one side, is pivotted a knife
having a handle at one side of pivot and a flat blade at the other which is a sufficient
length to extend over the mould plate. When the mould plate has had the stoppers or
other similar glass articles pressed therein in the ordinary manner it is taken from
the press and placed over the hole of our new or improved machine and rests on the
flange formed around said hole and obtains a suitable or required position by means
of being forced up to the regulator hereinbefore described so that each projection of
the bottom flat plate is immediately above each stopper or other similar article in

page_text: stopper plate. The handle of the pivotted knife is then pulled or forced in a horizontal
direction and the blade is thus caused to cut off the surplus metal or glass at the top
of the stoppers which is then removed in the usual way.
Where preferred however the surplus glass may be cut off and removed in any
other suitable way. After this operation the hand or fly wheel is turned round this
forces round the crank and pin and presses down the plate with the projections or pins
and the said pins force or release the whole of the pressed glass articles simultaneously
from the mould plate, and they fall into the hopper beneath and they are removed
therefrom when required by the takers in.
The fly or hand wheel is suitably balanced or weighted so that when it has been
turned round for the purpose specified it automatically returns to original position and
thereby again raises the flat plate and gives clearance for the mould plate to be
removed.
.
It is obvious that our new or improved machine may be worked by steam or other
power where preferred it only being necessary to apply a suitable fast and loose pully
to the horizontal shaft or any other suitable and ordinary means of transmitting
power may be employed.

COMPLETE SPECIFICATION.
A New or Improved Machine for Releasing or Forcing Glass
Stoppers or other similar Pressed Glass Articles from their
Moulds.
We SAM REDFEARN of Old Mill Glass Works Barnsley in the County of York
Glass Bottle Manufacturer, and WILLIAM HENRY MARSHALL of 42 Harbro Hills
Barnsley in the County aforesaid Glass Stopper Maker do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
Our invention relates to means for forcing or releasing glass stoppers or other
similar pressed glass articles from the moulds or mould plate wherein they have been
pressed, that is to say in all cases where a number of small glass articles are pressed
simultaneously in one mould plate our present invention relates to means for releasing
the same, and the object thereof is to force every pressed article from its respective
mould at one and the same time; to attain which we employ a new or improved
machine constructed and arranged in the manner set forth in the accompanying
drawings, of which the following is a description. Fig. 1..is a cross sectional elevation
and fig. 2 a front view of our improved machine.
Similar letters refer to corresponding parts in each figure.
On a pair of legs or frame A, A, we fix or arrange a table B, which is formed with
a suitable opening 6' along the sides of which is a lip or flange 6. Upon the table B
we fix or secure a fixing or standard C which has a bush or boss c¹ in the form of a
vertical bearing, and likewise a bush or boss in the form of a horizontal bearing,
which latter carries the horizontal shaft D. The said shaft D has secured to it either
by means of the key d¹ or in any other manner. a hand wheel or fly wheel E which is
suitably weighted at e¹ for the purpose hereinafter described.
The shaft D also receives a crank or disc G which is secured thereto either by means
of the key g¹ as shown or in any other way.
The disc G is arranged with a slot which receives the sliding portion or head j
of the crank pin J and also a screw K which has a bearing at k³ and in the top and
bottom of the slot g³ respectively. The screw K screws through the portion or head j¹
and has at its top a square portion for the purpose of receiving a spanner or key,
by which means the screw K may be turned and the position of the pin J adjusted
from time to time as required.

page_text: The vertical bearing or bush c¹ guides a vertical shaft or rod L which is hinged or
connected by means of a jaw m¹ and pin m³ to a connecting rod M the end m³ of
which works upon the pin J. The lower end of the vertical rod L is formed with an
enlargement or flange by which means a flat plate N is secured thereto by means of
set screws n'. Immediately beneath the plate N and attached to the same in any
suitable manner is another flat plate O which carries any suitable number of projec-
tions or pins p, and these extend a suitable distance below said plate O as shown at
fig. 1 for the purpose hereinafter described.
The pins p are preferably made of steel and are secured to the plate O by means of
being driven into suitable holes formed in said plate, and when pressure is applied to
the protruding points it is obvious that they are prevented being forced out of the
holes by means of the solid back or upper plate N. The pins are formed to a
suitable size and correspond in position and number to the moulds
the plate R.
The mould plate R fits in the opening 61 and rests upon the flanges b³.
formed in
When desired the portion of the table B on either side of the opening ы may be
arranged so that the width of said opening may be adjusted to suit any size of mould
plate R as will be well understood.
The mould plate R is made in the ordinary manner having any suitable number of
moulds 1.
Upon the table B in a suitable position as shown fig. 1 is arranged a regulator or
adjuster or stop S, which is composed of a screw S with nut s the latter screwed
through a boss or projection 6* which is either made with or attached to the upper
part of table B. The screw or regulator S may be adjusted from time to time to
suit the special length of the mould plate R being used, and the adjustment is made
for the purpose of causing the pins p in every case to come directly over the
moulds 1.
Under the table B and immediately below the mould plate R is arranged and fixed
a suitable container or hopper V having a removable bottom or sliding door v¹; and
secured to the legs or frame A, A, are suitable supports a' for carrying an ordinary
"takers in " shovel X.
At the side of the table is arranged a lever Y which carries by means of suitable
rods y' a knife z which is made a sufficient length to extend fully across the whole of
the mould plate R.
When the mould plate has had the stoppers or other similar glass articles pressed
into the moulds in the usual manner, it is taken from the press used for the said
purpose and then placed over the hole 6', and rested upon or carried by the flanges b³
of the table B; it is placed in such a position over the hole 6' and upon the flanges b
that one of its ends presses against the regulating screw S by which means it attains
a position so that each mould becomes situated directly under each pin or projec-
tion p as shown fig. 1. As soon as the mould plate R has been placed in said position
upon our improved machine the lever Y is pulled over to position shown by the broken
line fig. 1. thus bringing the knife z to the front of the surplus metal or glass which
has been left in the ordinary way upon the mould plate R; the lever Y is then pressed
back again to its original position with force, which causes the knife z to cut away
the said surplus metal or glass, when the same may be removed by any suitable means
or in any ordinary manner; after this has been done then in order to release or force
the stoppers out of their respective moulds at one and the same time it is only
necessary to give the hand or fly wheel E a turn, by which means the pin J causes
the connecting rod M, and vertical rod L, to force down the plates N and O and so
cause the lower ends of the projections or pins p to press upon the articles in the
moulds and thus release or force them therefrom, when they at once fall into the
receptacle or container V, from where they may be removed from time to time as
required, it only being necessary for the "taker in' to place the shovel X upon
the rests or supports a¹ under the hopper V, then remove the slide 1 by means
of pulling the handle when the stoppers will fall from the hopper V into said
shovel ✗, they may then be immediately removed to the annealing kiln in the

page_text: usual manner, and the door or slide v¹ again closed so that the hopper V is ready
for receiving more released stoppers.
The fly or hand wheel E being suitably weighted in the manner hereinbefore
described always attains the position shown at fig. 1 when not being worked or forced
round, by which means the pins p become clear of the mould plate R and the same
may be freely removed from, and easily replaced over the opening b¹.
It will be obvious that our said new or improved machine may be worked by steam
or other than manual power when preferred, it only being necessary to apply a suitable
fast and loose pulley to the shaft D and lengthen the same for the purpose, or that
any other ordinary means of transmitting power to our herein described improved
machine may be employed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A machine combined and arranged substantially as described and used for the
purpose specified.
2. In a machine for releasing or forcing glass stoppers or other similar pressed
glass articles from their moulds the combination of a horizontal rod D having
weighted wheel E and disc or crank G with a connecting rod M vertical rod L having
plates N and O substantially as described and illustrated at figs. 1 and 2 of the
accompanying drawings.
3. In a machine for releasing or forcing glass stoppers or other similar pressed
glass articles from their moulds the use of a knife z worked with a lever Y sub-
stantially as described and for the purpose set forth.
