Improvements in Apparatus for Use in the Manufacture of
Plate Glass.
I, WILLIAM WINDLE PILKINGTON of St. Helens in the County of Lancaster, Glass
Manufacturer, do hereby declare the nature of this invention to be as follows:-
'
The object is to provide more efficient apparatus for raising a pot containing
molten glass, slewing same into position tilting or casting righting the pot, slewing it
back again, returning to tram, rolling the cast metal, raising the roller and stowing
the sheets or plates into the desired part of the kiln or kilns, and withdrawing same.
The invention consists essentially in improvements on the apparatus secured to me
by British Letters Patent No. 4283 of the year 1879 has as novel features the
following parts in combination.
First. An overhead traveller combined with one or more swinging jibs by which
the glass pots are raised and also slewed into position for tilting and casting. The
same appliances slew the pot back to the tram from which it was taken.
Second. An overhead traveller combined with apparatus for giving motion to the
glass rollers along the table, and for raising them from the table when required.
Third. An overhead traveller combined with a wire rope or like appliance for
pushing or drawing sheets or plates into and out of the annealing kilns.
Fourth. An overhead traveller combined with Hydraulic pumps accumulator and
connections for giving motion to the raising slewing tilting returning roller actuating
stowing and withdrawing appliances.
Fifth. The combination with an overhead traveller having the appliances under any
or all of the heads above setforth, of belt rope or like gear and connections for giving
the necessary motion to the desired parts.
Sixth. Swing jib apparatus for raising, slewing, tilting, returning, roller actuating
and stowing and withdrawing appliances or any or a combination of these with one or
more cylinders pistons and connections for effecting the operations named.
It will be manifest the usual hydraulic and other connections for starting stopping
and giving the required motions are supplied.

*Manufacturer, 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 :-
The object is to provide more efficient apparatus for raising a pot containing

The invention which consists essentially in improvements on the apparatus secured
to.me by British Letters Patent No. 4283 of the year 1879 has as novel features the
following parts in combination.
First. An overhead traveller combined with one or more swinging jibs by which
the glass pots are raised and also slewed into position for tilting and casting. The

stowing and withdrawing appliances.
Fifth. The combination with an overhead traveller having the appliances under any
or all of the heads above setforth of belt rope or like gear and connections for giving
the necessary motion to the desired parts.
Sixth. Swing jib apparatus for raising slewing tilting returning, roller actuating,
stowing and withdrawing appliances, or any or a combination of these with one or
more cylinders pistons and connections for effecting the operations named.
It will be manifest the usual hydraulic and other connections for starting stopping
and giving the required motions are supplied:

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a side elevation, fig. 2 an end elevation, and fig. 3 a plan of apparatus
constructed in accordance with my invention.
1 overhead travelling stage carried on lines 2 in the usual way and actuated by
means of an endless rope 3 having continuous motion imparted to it from a stationary
engine. The endless rope 3 runs in contact with the grooved wheels 4. 5. 6. The
wheel 4 is secured to a shaft carrying a fast pulley 7. The wheel 5 is secured on
the shaft 8 which gives motion to the hydraulic pumps 9 through gearing 10
1.1. accumulator. To avoid confusion the pipes leading from the pumps to the
accumulator and from the accumulator to the various hydraulic cylinders as well as
the valves for opening and closing the ways leading to and from the said parts are not
shown as they are of any convenient construction and are made and connected in any
usual or suitable or well known manner. The wheel 6 is loose on the shaft 12. The
shaft 12 has a fast and two loose pulleys on it, and these pulleys are connected to the
pulley 7 by a straight lead and crossed belt; the shaft 12 is also provided with
gearing 13 for giving motion to the carrying wheels 14 of the stage 1.
These parts
operate in the usual manner for causing the crane to travel to and fro. 15 standards
carried by the stage 1 and having guides 16 around which fit the slide blocks 17, the
slide blocks 17 have bearings in which hydraulic cylinders 18 are free to oscillate.
19 rams attached to the standards 15 and fitting within the hydraulic cylinders 18.
20 tail pieces attached to the cylinders 18 and passing freely through the grooved
wheels 21 carried in bearings on the stage 1: the tail pieces 20 are square or of other
form so that they may pass to and fro freely through the wheels 21 but will partake
of the rotary motion thereof. 22 hydraulic cylinders carried by the stage 1 and
fitted with rams 23 which give motion to the chains 24 passing around the wheels 21.
25 jibs secured to the cylinders 18 and provided at their ends with bearings carrying
shafts 26 fitted with wheels 27 round which chains 28 which support the ports 29
pass. 30 hydraulic cylinders attached to the jibs 25 and provided with rams 31
which give motion by means of the chains 32 to the pulleys 33 on the shafts 26.
34 hydraulic cylinders carried by the stage 1 and provided with rams 35 which
actuate chains 36 passing around pulleys on the shafts 37 and pulleys 38 attached to
the weights 39 the free ends of the chains being secured at 40 to the stage 1.
41 chains passing round pulleys 42 on the shafts 37 and pulleys 43 on the uprights 44.
45 are vertical hydraulic cylinders attached to the stage 1, and have rams which give
motion to the chains 46 which pass over pulleys 47 on the stage 1 and carry the
roller 49. 48 table.
The action of the apparatus is as follows:-
The stage 1 is run to the required position by means of the belts and gearing 10.
The jibs 25 are swung round the desired distance by means of the hydraulic
cylinders and ram appliances 22. 23. and are lowered as far as necessary by the
cylinders and rams 18. 19. The pots 29 are slung on the chains 28 and the jibs
are raised and swung over the casting table by the hydraulic appliances. The pots are
then tilted by the hydraulic apparatus 30. 31. When the glass has been turned out
on the table 48, the roller 49 is drawn along over the glass by the hydraulic
apparatus 34. 35 until it reaches the other end of the table when it is raised two or
three inches by the ram appliances 45 in order to allow the glass to pass under it,
and be shoved into the annealing kiln by the apparatus 34. 35. The roller is then
lowered and returned to the other end of the table ready for the next casting.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed I declare that what I claim is :-
First. The combination of the overhead traveller 1 with one or more swinging
jibs 25 constructed and operating substantially as setforth.

page_text: Second. The combination of the overhead traveller 1 with hydraulic apparatus 34
and 45 constructed and operating substantially in the manner and for the purpose
setforth.
Third. The combination of the overhead traveller 1 with hydraulic appliances 34
constructed and operating substantially in the manner and for the purpose setforth.
Fourth. The combination of the overhead traveller 1 with hydraulic pump and
accumulator apparatus 9. 11. and connections substantially in the manner and or the
purpose set forth.
Fifth. The combination with an overhead traveller 1 provided with hydraulic
appliances under any of the first four heads of my invention, of belt rope and like
gear and connections substantially in the manner and for the purpose setforth.
Sixth. The various combinations of parts specified under the sixth head for the
purposes setforili.
