I, JOHN GARNET LIVERSIDGE of 3 Carey Street, Hunslet, Leeds in the County of
York, Glass Stopper Maker, do hereby declare the nature of this invention to be as
follows:-
In carrying out this invention, the object of which is to mechanically grind away,
the feeding gait or projection formed on the stopper or Ball, in the process of casting.
In accomplishing this, I mount in bearings a grinding Roller of Emery or other suit-
able material. To this Roller which is of considerable length, I impart a reciprocating
as well as a rotary motion.
I also provide and fix in front of the grinding Roller, a shaft carrying a plate wheel
at each end. Each plate wheel carries two centres, fixed opposite to each other. Two
stopper holders of rectangular form are suspended between the centres carried by the
plate wheels, each holder is formed by a top and a bottom plate, hinged together. A
Row of holes of less diameter than the stoppers to be ground, are drilled along the
axial edge of the bottom Holder. A strip of Rubber covers the opposite edge of the
top Holder. Winged nuts are provided to force the two plates together, the stoppers
are thus securely held between the holes in the bottom and the Rubber on the top
plate, with their shank ends projecting beyond the Holder, The Holders are centred
at their ends, for the reception of the Centres carried by the plate Wheels, and the
centres are so situated, that the stoppers in grinding, shall be ground from their own
centre. One of the plate Wheels carries two locking levers, to secure the Holders in
the proper angular position for presenting the stoppers to the grinding Roller, When
one of the Holders has reached this position, the locking lever is disconnected, and the
Holder is then free to gravitate around the suspended centres from its highest to its
lowest Position, being controlled in its descent by a Cataract Cylinder hereafter
described.
The plate Wheels carrying the Holders being mounted on a shaft, are rotated by
means of a Worm and Worin Wheel, till the position for grinding has been reached,
when a toothed lever falling into a notch in one of the plate Wheels throws the driving
worm out of gear, at the same moment that the toothed lever locks the plate Wheels,

with liquid, is so arranged, that at the time when the plate Wheels become locked in
position, a clawed lever attached to the Cataract cylinder piston rod engages with a
stud fixed in the Stopper Holder, The locking lever carried by one of the plate
Wheels is now withdrawn, and the Stopper Holder, being now connected with the
Cataract Cylinder, by its weight, forces the liquid through a port, controlled by a
coned regulating screw from the bottom to the top of the Cylinder. The coned regu-
lating screw thus determines the time which shall be taken for the Stopper Holder to
gravitate from its highest to its lowest position. A Cam carried by the clawed lever,
has now disconnected the claw from the Stopper Holder. The clawed lever and
Piston rod now ascend by means of a weighted lever, and are in readiness to engage
with and regulate the descent of the next Holder, which having now being filled with
stoppers, is rotated, untill it comes into position for the toothed lever again to lock the
plate wheels, when grinding again commences.
It will be evident that by modifying the form of the Holders, other stoppers not of
spherical form can be ground..

I, JOHN GARNET LIVERSIDGE, of 3, Carey Street, Hunslet, Leeds, in the County of
York, Glass Stopper Maker do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
In carrying out this invention, the object of which is to mechanically grind away
the feeding gait, or projection formed on the Stopper or Ball in the process of casting.
In accomplishing this, I mount in bearings, a Grinding Roller of Emery or other
suitable material. To this Roller, which is of considerable length, I impart a recipro-
cating as well as a rotary motion, I also provide and fix in front of the grinding
Roller, a shaft carrying a plate Wheel at each end. Each plate. Wheel carries two
centres fixed opposite to each other.
Two Stopper Holders of rectangular form, are suspended between the Centres
carried by the plate Wheels, each Holder is formed by a top and bottom plate, hinged
together. A row of holes of less diameter than the stoppers to be ground, are
drilled along the axial edge of the bottom Holder, a strip of Rubber covers the
opposite edge of the top Holder. Winged nuts are provided to force the two plates
together. The Stoppers are thus securely held between the holes in the bottom and
the Rubber on the top plate with their shank ends projecting beyond the Holder.
The Holders are centred at their ends, for the reception of the centres carried by the
plate Wheels, and the centres are so situated, that the stoppers in grinding, shall be
ground from their own centre. One of the plate Wheels carries two locking levers, to
secure the Holders in the proper angular position for presenting the stoppers to the
grinding Roller.

page_text: When one of the Holders has reached this position, the locking lever is disconnected,
and the Holder is then free to gravitate around the suspended centres from its highest
to its lowest position, being controlled in its descent, by a Cataract Cylinder hereafter
described.
The plate wheels carrying the Holders being mounted on a shaft, are rotated by
means of a worm and worm wheel till the position for grinding has been reached,
when a toothed lever falling into a notch in one of the plate wheels throws the driving
worn out of gear, at the same moment that the toothed lever locks the plate wheels.
A Cataract Cylinder fitted with foot valve, Piston and regulating cone, and filled
with liquid, is so arranged that at the time when the plate wheels become locked in
position, a clawed lever attached to the Cataract Cylinder piston rod engages with a
stud fixed in the Stopper Holder. The locking lever carried by one of the plate wheels
is now withdrawn, and the Stopper Holder, being now connected with the cataract
Cylinder, by its weight forces the liquid through a port controlled by a coned
regulating screw from the bottom to the top of the cylinder. The coned regulating
screw thus determines the time which shall be taken for the Stopper Holder to
gravitate from its highest to its lowest position, and consequently the time occupied in
grinding. When the Holder has reached it lowest position, a Cam carried by the
clawed lever, has now disconnected the claw from the Stopper Holder. The clawed
lever and piston rod now ascend, by means of a weighted lever, and are in readiness
to engage with and regulate the descent of the next Holder, which having now
been filled with stoppers, is rotated, untill it comes into position, for the toothed lever,
again to lock the plate wheels, when grinding again commences.
It will be evident that by modifying the form of the Holders, other stoppers not of
spherical form can be ground.
In the accompanying sheet of Drawings, Fig. 1 is a side and Fig. 2 an end elevation,
Fig. 3 is a plan view, Fig. 4 is a view of the Cataract Cylinder, Fig. 5 an enlarged
view of one of the Plate Wheels, and Figs. 6 and 7 show an end elevation and part
plan of one of the Stopper Holders.
A, is the Emery Roller, mounted on shaft B, and revolving in Bearings C. C. D is
a Pulley driven by Belt from shaft B. and through the medium of Pinion E. Spur
Wheel F. Shaft G Mitre Wheels H. H. giving motion to Shaft I and Crank J.
K is a Lever working between collars L. L. on fixed shaft M. and having movement
given it by means of Crank J and loose die O. the upper portion of the Lever being
connected to the grinding Roller Shaft by means of Cross head P and solid
Collars Q. Q. will give the desired reciprocating movement to the Roller.
Figs. 6 and 7 show the construction of the Stopper Holders, where R is the bottom
and S. is the top plate, attached together by Hinges T. T. U. V. are holes, of less
diameter than the Stoppers to be ground, drilled in the bottom Holder, ensuring the
Stoppers being accurately and expeditiously placed in position. V is a strip of Rubber
cemented to the top portion of Holder, for the purpose of securely holding the
Stoppers, during the process of grinding. W. W. W. are Nuts, rectangular in plan,
one quarter turn of which will secure and hold the stoppers in the Holder, by releasing
the Nuts, the top portion of Holder can be thrown back, when the ground stoppers
can be removed, and refilled.
The Holders are carried and supported to their work by plate Wheels X. X.
mounted on Shaft Y. and running in bearings Z. Z. The plate Wheels are provided
with Centres 1. 1. between which the Holders are suspended, and the Centres are
capable of adjustment by regulating screws 2. 2. sliding dies 3. 3. and lock nuts 4. 4.
The position of the centres carrying the Holders are so situated that a line between
the two Centres will cut and intersect the centres of the stoppers in the Holder.
Thus causing the stoppers to be ground from their own centre, and to the proper
radius.
Fig. 5 shows an end view of the two Holders, held in position by means of locking
Levers 5. 5. attached to one of the plate wheels, the jawed ends of these Levers engage
with a Stud 6. fixed in the end of each Holder. 7. is a Rubber or other spring to keep
the jawed ends in contact with the Stud 6. securing the Holders in the proper angular

page_text: position for presenting the Stoppers to the grinding Roller. Fig. 5 shows one Holder
in the grinding position and the other ready for emptying and refilling. If the locking
Lever 5. controlling the Holder that is in the position for grinding, is now discon-
nected, the Holder will by its weight, gravitate round the Centres 1. 1. from its
highest to its lowest position, when the grinding will have removed the feeding Gaits
on the Stoppers. The Holders are controlled in their descent by means of a Cataract
Cylinder shown in Fig. 4. where 8 is a Piston, 9 a coned regulating screw con-
trolling admission to the Port 10. communicating between the top and bottom of the
cylinder, A clawed lever 11. shown in Figs. 1 and 2. is attached to the crosshead of
the Piston rod, When one of the Holders has arrived in the grinding position, the
clawed end of Lever 11. will have hooked on to the stud 6 fixed at one end of the
Holder. The weight of the Holder will then force out the Oil from the bottom to the
top of the Cataract Cylinder, the time taken for this being determined by the coned
screw. The Holder having now reached its lowest position, which is determined by
the stop 13. coming in contact with the shaft Y. the inclined Plane or Cam carried by
clawed Lever 11. will through contact with Roller 14. have unhooked the clawed lever
from the stud 6. fixed in the end of Holder. The Ballance Weight 15. will now through
lever 16. cause the Piston rod of the Cataract Cylinder to ascend, and regain its
.former position.
To provide means for the rotating and stopping of the Plate Wheels and Stopper
Holders, an upright shaft 17. fitted at one end with a worm 18. has motion given to it
by means of Belt or Cord 19. from Roller Shaft B. driving a grooved Pulley fixed
at the bottom end of upright shaft 17. The upper end of the shaft 17. is carried by a
Lever 20. operated by the detent Lever or Handle 21. by raising the Handle the
Detent will be withdrawn from the notch 22 in the Plate Wheel, and the worm 18.
will be put into gear with the Worm Wheel fixed on the end of the plate wheel shaft Y.
which it will rotate untill the Detent 21 falls into the opposite notch in the plate
wheel, stopping its further progress, and throwing the worm out of gear with the
Worm Wheel. When grinding again commences, a straight edge 23 extends the full
length of the Holder, being carried by the Shaft 24. and Bearings 25, is for the
purpose of a guide in filling the Holders with Stoppers. The shank ends being placed
on the edge of the straightedge, or in notches formed on its edge, ensure the shanks
being placed at the proper level. The straightedge, on the Detent Handle being
operated, will fall back from the Holder through Horseshoe Lover 26 being in contact
with Lever 20. The ballance weight 28, on the Detent Lever falling into one of the
notches, will cause the straightedge to again occupy the previous position.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is.
