PROVISIONAL SPECIFICATION.
Improvements in Glass-lined Tubing.
We, DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the
County of York, Glass Bottle Manufacturer and ROBERT MORANT, 200 Doncaster
Road, Barnsley in the said County Mechanical Engineer do hereby declare the
nature of this invention to be as follows:
Our present invention has for its object the manufacture of glass-lined tubing
so that in the one tube there can be two or more separate tubes inserted thus
enabling one or more complete circuits to be secured by means of one metal
tube lined with two glass tubes.
According to our present invention we cast or make a flanged pipe of metal
or steel somewhat on the same principle as the two barrels of a double barrelled
gun only that there is an outside flange on each side of the barrel for connecting
the pipes to each other. Following out this principle the pipe thus cast may
be of any preferred shape and the flanges may also be varied to meet require-
ments. We take this double barrelled or multiple-barrelled pipe when so cast
and introduce into each barrel a suitable glass tube and we then introduce
between the glass and the barrel a suitable packing of cement or other substance.
In some cases we slightly countersink one end of each of the barrels for allowing
the glass of the tube to be thicker at such end. A packing of gutta percha or
other suitable substance is introduced between the ends of each double-barrelled
or multiple-barrelled pipe so as to prevent any loss of electric current at the
joints. In some cases we use a double-eyed or multiple-eyed flange through
which we pass two or more glass pipes without any protection of iron in the
centre, but using in some cases a covering of wood or other cheap material.
We would remark that the double-barrelled or multiple-barrelled pipe or the
double-eyed or multiple-eyed flanges may be of any size according to the size
the glass tubes are required and making allowance for the packing between the
glass and iron.

Improvements in Glass Lined Tubing.
We, DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley, in the
County of York, Glass Bottle Manufacturer and ROBERT MORANT, 200 Doncaster
Road, Barnsley in the said County Mechanical Engineer 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 :--
Our invention has for its object the manufacture of protected glass lined tubing
so that in the protecting tube there can be two or more glass tubes inserted
thus enabling one or more complete circuits to be secured by means of one metal
tube lined with two or more glass tubes.
Our invention also relates to means for attaching and coupling up glass tubes
that are not protected by metal but by some lighter and less expensive material.
We carry out our invention in the following manner reference being had to the
accompanying drawings in which
Figs. 1 and 3 are sectional elevations and Figs. 2, 4, and 5 plan views.

page_text: Referring to Figs. 1 and 2, a is the metal protecting tube flanged at both ends
at and containing the glass tubes ce da packing of cement or other suitable
material securing the glass tubes in position and enabling them to resist the
pressure they may be called upon to bear.
The glass lining tubes having been inserted in position in the interior of the
protecting tube, and secured therein by the packing of cement, the ends of the glass
tubes can be ground level with the faces of the flanges when the completed tubes
can be coupled up by bolts compressing a gutta percha or other suitable jointing
ring.
In Fig. 3, the glass tubes are formed with annular interrupted projections at
either end as shown at ee, Fig. 4 showing in plan view the contour of the pro-
jections is a flange of metal in two parts having an internal opening of the
formation shown by Fig. 5, gg being projections formed with the flange; and ha
jointing ring.
;
The separate portions of each flange having been threaded on the glass tubes by
the projections carried by the flange being placed opposite the spaces shown at i
(Fig. 4) the flanges can be passed over the ends of the tubes; this having been
done the flanges are rotated till the projections on the flange bear on the inter-
rupted annular enlargements e e formed on the ends of the glass tubes. A. suitable
jointing ring being now inserted between the ends of the tubes they can be drawn
together and made pressure-tight by the bolts.
We have described and illustrated a protecting tube containing two glass tubes
and the method adopted for coupling up two unprotected or only slightly-protected
glass tubes; but it will be evident that the constructions adopted will apply equally
to a greater number of glass tubes.
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. In a metal protecting tube the combination of two or more glass lining tubes
secured by means of cement or in any other suitable manner for the purpose herein
described, and as illustrated by Figs. 1 and 2.
2. The method of coupling together two or more unprotected glass tubes as shown
and described with reference to Figs. 3, 4, and 5.
