PROVISIONAL SPECIFICATION.
Improved Means of Manufacturing Glass Vessels and Adapting the
same for the Storage and Conveyance of Compressed Gases, and
for similar purposes.
I DAN RYLANDS of Stairfoot near Barnsley in the County of York Glass
Bottle Manufacturer do hereby declare the nature of this invention to be as
follows:-
:-
My present invention has for its object the manufacture of glass vessels in such
a way that great strength will be secured so as to enable these vessels to be used
for the bottling of compressed carbonic acid gas or compressed oxygen or other
gases, or for similar purposes, also so as to provide such vessels with secure
and easy means of being made air-tight and yet affording a good opportunity
of releasing their contents when the same are required to be used also for
adapting these vessels for the conveyance of such gases by protecting the outside
thereof with a suitable case of either wood or a combination of wood and sawdust
or other suitable protecting medium. In carrying out my invention 1 manu-
facture, in a suitable machine worked on the combined pressing and blowing
process, any suitable shape of glass vessel, the one which I prefer for securing
the greatest strength being a solid ended glass tube having this solid end nicely
rounded off so as to secure the greatest strength.
I form this tube with a suitable shoulder and on the outside of the mouth
of the tube, or on the inside thereof as may best meet the requirements,
I form a screw thread or inclined projection so that a suitable cap carrying
a suitable tap may be fastened in secure and air-tight position on the neck
or top part of the said solid ended tube. The glass vessel may of course be
of any other desired or suitable shape. After having formed the glass vessel
and carefully annealed the same and having attached thereto the mouthpiece I
place this glass vessel in a case so made that it will give the maximum strength
and protection at the minimum of weight and I make the case of sufficient size
that it will allow of a space between the outside glass vessel or tube and the inside
of the case and this space 1 fill with either sawdust or with wood spinnings or with
any other suitable packing and by this means I secure protection against danger
of injury from the glass bursting. The top or cap is outside this case so that the
glass vessel can be filled or emptied without taking it out from the case.

COMPLETE SPECIFICATION.
Improved Means of Manufacturing Glass Vessels and Adapting the
same for the Storage and Conveyance of Compressed Gases, and
for similar purposes.
I, DAN RYLANDS of Stairfoot near Barnsley in the County of York Glass
Bottle 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 :-
My invention has for its object the manufacture of glass vessels in such a way
that great strength will be secured so as to enable these vessels to be used for the
bottling of compressed carbonic acid gas or compressed oxygen or other gases, or
17

page_text: for similar purposes also so as to provide such vessels with secure and easy means
of being made airtight and yet affording a good opportunity of releasing their con-
tents when the same are required to be used also for adapting these vessels for the
conveyance of such gases by protecting the outside thereof with a suitable case of
either wood or a combination of wood and sawdust or other suitable protecting
medium.
In the accompanying sheet of drawings
Figs. 1 and 2 are sectional views of moulds and apparatus necessary for the
manufacture of the glass vessel shown in its protecting case by Fig. 3 ;
Fig. 4 is a plan view of the protecting case.
In Figs. 1 and 2, a is the outer blowing mould made in two parts and hinged
together at b, c the pressing or inner mould guided in an up and down direction by
the cylindrical guide d, e the pressing plunger also suitably guided, the mould
bottom guided and carried by the spectacle lever g and capable of being brought
under the blowing mould as shown by Fig. 2. The outer mould is provided with
latches and handles for securing and opening the two halves of the mould in the
usual manner. The method of operating the above-described apparatus to produce
a pressure-resisting tube in accordance with my invention is as follows:-The
inner mould c being at its highest position as shown by Fig. 1 a sufficient quantity
of molten metal is charged into the cavity constituting the inner portion of the
mould, the plunger e descending displaces the molten metal and causes it to assume
the formation shown by Fig. 1. The plunger e and inner mould c being now with-
drawn from the interior of the parison tube and interior of blowing mould
respectively will leave the parison tube suspended by the mouth portion as shown.
The mould bottom f being now brought under and central with the blowing mould
and elevated into the position indicated by Fig. 2 by the re-ascent of the inner
mould the mould cover or blowing apparatus being placed in position and air
under suitable pressure admitted into the interior of the parison tube, will cause it
to gradually expand and assume the configuration of the interior of the blowing
mould.
The mould being now unlocked and opened, the finished product can be removed
to the annealing oven and the process repeated.
In Fig. 3 the pressure resisting tube is surrounded and enclosed within a casing
of wood or other suitable material which may be of any convenient sectional figure,
but for the purpose of illustration I will describe the method of sheathing the tube
in a case having four sides. The sides k k surrounding and securing the end piece
having being fastened together by nails or screws, and the casing still further
strengthened and armoured by the bands of iron wire m m m m passing around it.
The pressure resisting tube is now placed in the interior of its casing and sawdust
or other suitable material is firmly rammed into the space between the exterior of
the tube and the interior of the casing. The end piece n being next passed into
position through the openings formed in the two sides oo and the rebates or
grooves carried by the sides kk (see Fig. 4) will complete the building up of the
wood casing, a further wrapping of wire q around that portion of the case
surrounding the end pieces n will secure the end and prevent its removal. The
completion of the sawdust packing is effected by means of the threaded holes rr
which are closed by threaded plugs of wood or metal.
I have illustrated and described the formation of a pressure resisting tube having
an external screw thread, but it will be evident that instead of screw threads
inclined planes or interrupted screw threads may be employed and that where so
desired an internal screw thread may be used.
The cap or top is screwed or otherwise fastened on the end of the tube in an
airtight position and this cap or top may carry a suitable tap. The top or cap is
so arranged outside the case that the glass vessel or tube can be filled or emptied
without taking it out from the case. The glass vessel may of course be any other
suitable shape than the one illustrated.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The manufacture of glass tubes or similar glass vessels for the storage of com-
pressed gases and for similar purposes as described and shown with reference to
Figs. 1 and 2 of the accompanying drawings or any mere modification thereof.
2. The special arrangements for packing and protecting such tubes in such a
way that the contents can be liberated without removing the tube from the case as
shown and described with reference to Figs. 3 and 4 of the annexed drawings or
any mere modification thereof.
