PROVISIONAL SPECIFICATION.
Improvements in Gas Storage Apparatus.
I, WILLIAM THOMAS Walker, of Bishopswood Road, Highgate, in the
County of Middlesex, Esquire, do hereby declare the nature of this invention to
be as follows:-
:-
The object of my invention is to make a gas storage apparatus (consisting of a
lift or lifts and a water tank or receptacle) so that it can be economically erected
in locations which would otherwise not be suitable or which would ordinarily
require expensive foundations and so also that the ground space covered by the
gas storage apparatus can be utilized as stores for coal, coke, oxide of iron or lime
or as a general warehouse for the storage of goods or for other purpose.
According to my invention I make an annular water tank or receptacle for
containing the water of the water seal in which the gasholder ascends and descends
and this is erected either on or above the ground level. The space enclosed by the
iuner side of this annular tank or receptacle is provided with a gas and watertight
roof which covers the said space and is preferably, to ensure gas tightness, covered
with water which is most simply done by its being situated at such a level that the
water of the water seal covers and seals the upper side thereof but only to a
shallow depth so that the roof need not be constructed of such excessive strength
and consequently cost as would be requisite if the depth of water above it were
equal or about equal to the depth of the annular tank or receptacle. The annular
tank or receptacle may be erected on a wall or on other equivalent support such
for instance as girders and columns in which case the space within can be had
access to on the ground level whereas when the bottom of the annular water tank
or receptacle is on the ground level there will have to be inclined passages down-
ward under the water receptacle and upward into the space enclosed by the annular
water tank or receptacle.
A wooden structure for supporting the crown of the lift when in its lowest
position may be erected on the aforesaid roof.

COMPLETE SPECIFICATION.
Improvements in Gas Storage Apparatus.
I WILLIAM THOMAS WALKER of Bishopswood Road Highgate in the County
of Middlesex Esquire 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 my invention is to make a gas storage apparatus (consisting of a
gas holding lift, or lifts, and a water tank, or receptacle) so that it can be
economically erected in locations which would otherwise not be suitable, or which
O would ordinarily require expensive foundations; and so also that the ground space
covered by the gas storage apparatus can be utilized as stores for coal, coke,
oxide of iron, or lime, or as a general warehouse for the storage of goods, or for
other purpose.
According to my invention I make an annular water tank, or receptacle, for
5 containing the water of the water-seal in which the gas holder ascends and descends
and this is preferably erected on, or above, the ground level. The enclosed
space

page_text: by the inner side of this annular tank or receptacle is provided with a gas-tight
roof which covers the said space and is preferably, to ensure gas tightness, covered
with water which is most simply done by its being situated at such a level that the
water of the water seal covers and seals the upper surface thereof but only to a
shallow depth so that the roof need not be constructed of such excessive strength
(and consequently cost) as would be requisite if the depth of water were equal, or
about equal, to the depth of the annular tank or receptacle. The annular tank or
receptacle may be erected above the ground level on a wall, or on other equivalent
support; such for instance as girders and columns, in which case the space within
can be had access to on the ground level whereas when the bottom of the annular
water tank or receptacle is not above the ground level there will have to be inclined
passages downward under the annular water tank or receptacle and upward into the
space enclosed by the said water tank or receptacle.
An inexpensive wooden structure for supporting the crown of the lift when in its
lowest position is erected on the aforesaid roof. As this structure is of but small
height the cost of it is but small.
And in order that my invention may be well understood I have shewn, in the
accompanying drawing, gas storage apparatus constructed, or arranged, in accordance
therewith.
The said drawing shews in vertical section a single lift gas storage apparatus
made according to my invention. A and B are the outer and inner sides
respectively of the annular water tank or receptacle. C is the space which may
be used as a storage for coal, coke, oxide of iron, lime, or other materials, or as a
warehouse. Dis the gas-tight roof covering the said space and having above it
a small depth of water as shewn forming a perfect seal all over it. The lift E rises
and falls in the water seal as gas is admitted to the space F or drawn off therefrom.
G shews passages by which access can be gained to the space C.
The gas holder and tank are shewn as being supported upon a wall H by which
means access can be had to the space C on the ground level by arches doorways or
passages as at G in the wall H, whereas if the gas holder and tank be not on the
ground level it will be necessary to make inclined passages in the ground down to
and under the tank to give access to the space C. J is the wooden structure for
supporting the crown e cf the lift when in its lowest position. Owing to this
structure being erected on the roof D there is considerable economy in the amount
of timber work necessary to support the crown. Although I have shewn but one
lift it is evident that two or more lifts may be used if desired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
A gas storage apparatus with an annular water tank, or receptacle, and gas-tight
roof enclosing a space for storage or other purpose substantially as hereinbefore
described.
