page_text: PROVISIONAL SPECIFICATION.
A New or Improved Gas Holder.
We, WILLIE RILEY, of the Firm of Riley Brothers, Limited, of 55 & 57,
Godwin Street, Bradford, in the County of York, Lantern Outfitters, and ABRAM
KERSHAW, of Dorrington Street, Leeds, in the County of York, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:--
This invention relates to a new or improved gas holder.
For this purpose we employ an outer vessel of suitable capacity preferably of
cylindrical form and an inner vessel or plunger fitting easily in it. This vessel
and plunger are connected together by an impervious flexible sleeve of india
rubber or other suitable material surrounding the plunger and hermetically
attached by one end round the top of the outer vessel and the other end is
hermetically secured round the plunger preferably rather less than half way
down. The sleeve permits the plunger to rise when gas is passed into the outer
vessel to approximately twice the distance between the points of attachment of
the sleeve to the other vessel and plunger when the latter is at its lowest point.
The plunger is preferably made hollow and open at the top so that it may be
more or less filled with water to weight it..

the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
-
This invention relates to a new or improved portable gas holder particularly
applicable for holding oxygen gas for supplying lime light apparatus.
For this purpose we employ an outer vessel of suitable capacity preferably
of cylindrical form and an inner vessel or plunger fitting easily in it. This vessel
and plunger are connected together by an impervious flexible sleeve of india-
rubber or other suitable material surrounding the plunger and hermetically
attached by one end round the top of the outer vessel and the other end is hermeti-
cally secured round the plunger preferably rather less than half way down. The

Reference is to be had to the accompanying sheet of drawings, forming a part of
this specification in which similar letters of reference indicate corresponding
parts in each of the figures.

The inner cylinder or plunger A when the holder
outer cylinder B. Both cylinders are completely closed at the bottom and the
sides of A are connected at A2 to the top of B by the annular flexible india-rubber
sleeve or connection C. This connection allows the cylinder A to rise from
the position shown in Figure 1 to that shown in Figure 3 whilst the holder is
filled with gas. The cylinder A is made open at the top so that it can be
readily filled with water or its equivalent to weight it. The vessel through which
the gas is passed to wash it is also preferably placed in the cylinder A. The feed
and delivery pipes may be connected to the cylinder B. In this case the wash
vessel is connected to the cylinder B by a flexible tube.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is;-.
An oxygen gas holder consisting of an external case or vessel of cylindrical or
other suitable form and an internal case or vessel of similar form coupled
together by a flexible connection, substantially as herein shown and described
and illustrated in the accompanying drawings.
