PROVISIONAL SPECIFICATION.
Improvements in Coupling and Fixing Glass Tubes for Containing
Electric Wires.
We DAN RYLANDS of Shepcote, Stairfoot, near Barnsley, in the County of
York, Glass Manufacturer, and SIDNEY SLATER of Stairfoot aforesaid do hereby
declare the nature of this invention to be as follows:-
The object of our present invention is to provide a simple means of coupling
together glass tubes for containing electric wires, and to secure means for the
economical fixing and protection of such glass tubes.
According to our invention we take a ring or collar of india rubber or other
suitable material of proper size to fit tight on the ends of the glass tubes we desire
to couple together. The end of one glass tube is passed about half-way into this
india rubber ring, or collar, or socket; and the end of another glass tube is forced
on the opposite side into the remaining portion of the india rubber ring or socket,
which fits tight on both ends of the glass tubes, holding them securely together and
forming a water-tight joint. In this manner we attach together any number of
glass tubes or pipes; and our invention is also adapted for coupling together either
bends or tees, or crosses of glass tubes, as well as straight pieces.
After coupling the glass tubes together in the manner described we take a casing
of wood or other suitable material made in two sides or halves to receive and fit
over the glass tubes. The inner portion or side of each half of this wood casing
or cover has semi-cylindrical grooves running the whole length of the wood, such
grooves being in shape and diameter to suit the glass tube intended to be laid
therein. An enlarged cavity is also made in that portion of the wood casing where
the india rubber collar or socket requires the same, and these enlarged cavities are
of the proper size and shape to allow the rubber sockets to be embedded therein.
Thus by being embedded in these cavities in the wood casing the rubber sockets
not only secure a water-tight joint at the ends of the glass tubes but also serve to
hold the glass tubes more safely and securely together. It will be clearly
understood that the grooves and cavities in each half of the casing are sufficiently
deep to cover half of one side of the glass tubes and india rubber sockets, and that
when both halves of the casing are brought together a complete circular hole is
obtained in the casing to receive and cover completely the glass tube and the
rubber sockets. The two sides or halves of the wood casing may be secured
together by means of screws or in any other suitable manner, thus firmly holding
and protecting the glass tube or tubes which in this manner form a perfect
insulation for electric wires.
The wood casing may be made in any suitable lengths and each length joined
together by one side or half of one length overlapping the opposite side or half of
another length. Or the lengths of casing may be suitably secured together in any
other practicable manner.
It will be clearly understood that two or any suitable number of glass tubes may
according to our invention be protected between the two halves of the wood casing
in the manner before described, it being only necessary to adapt the grooves in the
casing to the size and number of the glass tubes to be protected. Or the wood
casing may consist of any number of thicknesses of wood secured together in layers
one over or one against another in any suitable way, and carrying grooves to form
circular holes in any desired number for receiving the glass tubes.
Our improved casing can also be adapted for receiving and protecting tees or
bends or crosses, and is also equally adaptable for receiving and protecting square
or any other section or shape of glass tubes in any suitable number.
The india

page_text: rubber sockets are also adaptable to square or round as well as any other section or
shape of glass tube.
With our glass tubes coupled and protected as before described naked or
unprotected electric wires may be used for electric lighting purposes.

COMPLETE SPECIFICATION.
Improvements in Coupling and Fixing Glass Tubes for Containing
Electric Wires.
We, DAN RYLANDS of Shepcote Stairfoot, near Barnsley in the County of
York, Glass Manufacturer and SIDNEY SLATER of Stairfoot aforesaid do hereby
déclare 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 our present invention is to provide a simple means of coupling
together glass tubes for containing electric wires and to secure means for the
economical fixing and protection of such glass tubes.
In the drawing which accompanies this Specification
Fig. 1 shows in sectional elevation our improved method of coupling up by
means of a rubber socket two straight lengths of glass tube.
.
Figs. 2 and 3 illustrate the coupling up of straight lengths of tube with a bend,
cross, tee, and elbow, and also shows the application of the wood protecting
covering.
Fig. 4 is an end elevation in which four tubes are shown enclosed in one
protecting casing.
According to our invention we take a ring or collar a (Fig. 1) of india rubber
or other suitable material of proper size to fit tight on the ends of the glass
tubes and we desire to couple together. The end of one glass tube is passed
about half-way into this india rubber ring or collar, or socket; and the end of
another glass tube a is forced on the opposite side into the remaining portion of the
india rubber ring or socket, which fits tight on both ends of the glass tubes, holding
them securely together and formning a water tight joint. In this manner we attach
together any number of glass tubes or pipes and our invention is also adapted for
coupling together either bends or tees, or crosses of glass tubes, as well as straight
pieces as shown by Fig. 2 and 3.
After coupling the glass tubes together in the manner described we take a
casing of wood or other suitable material d made in two sides or halves to receive
and fit over the glass tubes. The inner portion or side of each half of this wood
casing or cover has semi-cylindrical grooves e e (Fig. 4) running the whole length
of the wood, such grooves being in shape and diameter to suit the glass tube
intended to be laid therein. An enlarged cavity is also made in that portion
of the wood casing where the india rubber collar or socket requires the same, and
these enlarged cavities are of the proper size and shape to allow the rubber sockets
to be embedded therein. Thus by being embedded in these cavities in the wood
casing the rubber sockets not only secure a water-tight joint at the ends of the
glass tubes but also serve to hold the glass tubes more safely and securely together.
It will be clearly understood that the grooves and cavities in each half of the
casing are sufficiently deep to cover half of one side of the glass tubes and india
rubber sockets, and that when, both halves of the casing are brought together
complete circular or other shaped hole is obtained in the casing to receive and
cover completely the glass tube and the rubber sockets. The two sides or halves
of the wood casing may be secured together by means of screws y (Fig. 4) or in.
L

page_text: any other suitable manner thus firmly holding and protecting the glass tube or
tubes which in this manner form a perfect insulation for electric wires.
The wood casing may be made in any suitable lengths and each length joined
together by one side or half of one length overlapping the opposite side or half of
another length as shown by Fig. 3 at h. Or the lengths of casing may be suitably
secured together in any other practicable manner.
It will be clearly understood that two or any suitable number of glass tubes may
according to our invention be protected between the two halves of the wood casing
in the manner before described, it being only necessary to adapt the grooves in the
casing to the size and number of the glass tubes to be protected. Or the wood
casing may consist of any number of thicknesses of wood as shown by Fig. 4
secured together in layers one over or one against another in any suitable way and
carrying grooves to form circular or other suitable holes in any desired number
for receiving the glass tubes.
Our improved casing can also be adapted for receiving and protecting tees or
bends or crosses and is also equally adaptable for receiving and protecting square
or any other section or shape of glass tubes in any suitable number. The india
rubber sockets are also adaptable to square or round as well as any other section
or shape of glass tube.
With our glass tubes coupled and protected as before described naked or
unprotected electric wires may be used for electric lighting purposes.
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. The improved method of coupling together glass tubes, bends, elbows, and
crosses by means of a socket of rubber or other elastic material for the purpose
herein described and illustrated.
2. In combination with the before-mentioned method of coupling glass tubes,.
the use of our improved casing for fixing and protecting the coupled glass tubing.
substantially as described and illustrated.
