TKWVIDIUNAL SPECIFICATION.
Improvements in Apparatus for the Manufacture of Sheet and Plate
Glass with Embedded Metallic Wire.
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 of this invention is to produce sheet and plate glass of excellent
quality and strength having embedded therein metallic wire, at a materially
reduced price.
For the above purpose I make use of two main rollers, each with a small roller,
each pair of rollers producing a sheet of glass. The metallic wire either in sheets
or in one long continuous piece is fed between these sheets of glass, which are
pressed on to the wire and each other so as to make one solid sheet having the wire
embedded therein. Suitable guides and side pieces are used for the supplying of
the molten glass and the regulation of the thickness of the sheet. The metallic
wire may be fed through a shoot or from a suspended coil. The sheet of glass
when it leaves the rollers may be cut off in lengths, as desired, by suitable
appliances.
Further, for this purpose, I make use of one table with two large and one small
roller. With the first large roller I produce a slieet of about half the thickness of
the finished sheet or plate, and upon that, place the wire netting by means of the
small roller, on the top of which when it is complete, I afterwards, with the second
roller, roll a sufficient quantity of glass to finish the plate. The wire netting
may be fed either in sheets or from a suspended coil. Suitable appliances may be
arranged for cutting the wire netting in lengths as required.

Improvements in Apparatus for the Manufacture of Sheet and Plate
Glass with Embedded Metallic Wire.
I WILLIAM WINDLE PILKINGTON of St. Helens in the County of Lancaster
Glass 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 of this invention is to produce at a materially reduced price sheet
and plate glass of excellent quality and strength having embedded therein metallic
wire.
For the above purpose I make use of two main or large rollers each combined
with a small roller to produce a sheet of glass. The metallic wire in the form of
netting and either in sheets or in one long continuous piece is fed between the
sheets of glass formed by the above mentioned rollers, and the said sheets of glass
are pressed on to the wire and together so as to make one solid sheet having the

page_text: wire embedded therein. Suitable guides and side pieces are used in connection
with the supplying of the molten glass for regulating the width and thickness of the
sheet.
The metallic wire may be fed through a shoot or from a suspended coil. The
sheet of glass when it leaves the rollers may be cut off in lengths as desired by
suitable apparatus.
DESCRIPTION OF THE DRAWINGS.
Fig. 1. is a vertical longitudinal section, and Fig. 2 an end elevation of apparatus
under my invention.
a, are two main or large rollers carried on shafts 6 free to rotate in bearings in
the frame c. dare small rollers carried on shafts e also free to rotate in bearings
on the frame c. f, are toothed wheels on the shafts b, and 9 are toothed wheels on
the shafts e. The wheels and g are in gear and their pitch circles are in the same
proportion as the diameters of the rollers a and d. Motion is given to the rollers
by means of chain, toothed, or other suitable driving gear coupled to the shafts b,
or preferably the two shafts bare coupled by toothed wheels, and one shaft used as
the driver. The bearings which carry the shafts.e are free to move radially from
the centres of the shafts b in the frame c, and the distance between the rollers a
and d is regulated by means of side pieces or flanges h on the shafts e which bear
against the surface of the larger rollers a. Any required distance between the
surfaces of the rollers a and d is obtained by using side pieces h of suitable
diameter. If required springs or weights may be used to keep the small
rollers pressed with sufficient force towards the large rollers. i, are guides
which rest on the rollers a and regulate the width of the sheet of glass.
The said guides are kept at the required distance apart by bolts or tie rods j.
k is the glass which forms a sheet on each of the rollers a as they rotate in the
direction of the arrows. is the wire which is fed from a roll m, or through a
shoot as desired. The said wire may pass directly between the sheets of glass on
the rollers a as shown by the full lines, or it may be and preferably is directed first
on to the sheet of glass on one roller by means of a guide roll n. A continuous
sheet of glass with embedded wire may be made and cut into lengths after leaving
the rollers, but I prefer that the wire should be fed to the rollers in lengths equal
to the sheets required, sufficient glass being supplied to each roller to coat the wire
on each side to the necessary thickness. o, are trollies beneath the rollers on to
which the sheet is directed by the guides p. Any suitable means may be used for
the removal of the glass, and when continuous sheets are made, rotating or other
suitable blades are used to sever the said sheet into lengths.
Having now particularly described and ascertained the nature of my said inveu-
tion and in what manner the same is to be performed I declare that what I
claim is:-
First. The combination of two main or large rollers each with a smaller roller
for producing sheets of glass and with with central feed appliances for wire for the
purpose set forth.
Second. Large rollers a geared with small rollèrs d and provided with wire
feeding devices for the purpose set forth.
Third. The combination of large rollers a with adjustable rollers d, guides i, and
wire feeding devices for the purpose set forth.
Fourth. Apparatus for making sheet glass with wire embedded, consisting of a
pair of large rollers combined with a pair of small rollers, glass and wire feeding,
and sheet take off devices, substantially as set forth.
