the Cups of Telescopic Gasholders.
I SAMUEL CUTLER of Providence Iron Works, Millwall, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the construction and application of apparatus
whereby the cup or cups of telescopic gasholders may be supplied with steam, hot
water, or other fluid for the melting of ice, for the prevention of the water being
frozen therein, or for other purposes.
Under ordinary circumstances the upper lift or lifts of the gasholder on rising
carry with them the cup or cups filled with water but on rising above the top of the
tank the water is exposed in severe weather to the liability of being frozen, or under
heavy gales of wind to being blown out and the seal broken thus allowing of a
serious escape of gas, and it is with a view to remedy these conditions that the
present invention has been devised.
In order that this invention may be carried out I place at the edge of the tank, a
pipe which may encircle or partly encircle the gasholder. From this pipe rise one,
two, or more vertical pipes which reach to a certain distance above the top of the tank.
To the upper end of each of these pipes there is attached a strong flexible tube long
enough to reach and enter the cup when at its extreme height. Each flexible tube is
supported by passing over a pulley which is suspended by a cord, chain or rope that
passes over another sheave or pulley fixed to the upper part of the guide column,
girder or other convenient means of support, the other end of the cord, chain or rope
being provided with a counterpoise weight so that on the rising and falling of the

the Cups of Telescopic Gasholders.
1, SAMUEL CUTLER of Providence Iron Works, Millwall, in the County of
Middlesex, 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 :-
This invention has reference to the construction and application of apparatus
whereby the cup or cups of telescopic gasholders may be supplied with steam, hot
water or other fluid for the melting of ice, for the prevention of the water being
frozen, or for other purposes.
Under ordinary circumstances the upper lift or lifts of the gasholder on rising
carry with them the cup or cups filled with water but on rising above the top of the
tank the water is exposed in severe weather to the liability of being frozen, or during
heavy gales of wind to being blown out, and the seal broken, thus allowing a serious
escape of gas, and it is with a view to remedy the effect of these conditions that the
present invention has been devised.
For the more easy understanding of this invention drawings are attached hereto,
Fig. 1 being a side elevation of a portion of a telescopic gasholder and column with
the outer lift partly up, and with the present invention applied, and Fig. 2 shows the
position of the various parts when the outer lift is at its full height.
In order that this invention may be carried out I place at the edge of the tank a
pipe which may encircle or partly encircle the gasholder. From this pipe rise one, two,
or more vertical pipes A which reach to a certain distance above the top of the tank.
To the upper end of each of these pipes there is attached a strong flexible tube B
long enough to reach and enter the cup when at its extreme height. Each flexible
tube is supported by passing over a pulley C which is suspended by a cord, chain, or
rope
ope that passes over another sheave or pulley F fixed to the upper part of the guide
column, girder, or other convenient means of support, the other end of the cord,
chain or rope being provided with a counterpoise weight G, so that on the rising and
falling of the gasholder the slack of the flexible tube is always taken up. Instead
of the flexible tube or tubes themselves entering the cup, the tube or tubes may be
connected to a pipe D attached to the grip of the outer lift, or lifts, and partly or
entirely encircling the same, and from this pipe any number of short pipes E baving
valves H may descend and enter the cup.
By connecting the pipe at the top of the tank with a supply of steam, hot water,
or other fluid, the steam or fluid may be injected into the cup when the holder is at
any altitude, and thus prevent the freezing of the water therein, or melt ice that may
have been already formed. If the pipe is connected to a water supply, water also may
be injected into the cup when the gasholder is at any altitude for the purpose of
restoring liquid to the cup, should any portion of the water be lost by leakage, heavy
gales, or other causes.

page_text: It is obvious that the foregoing apparatus may be adapted to gasholders having
three or more lifts.
Both to obviate condensation of steam and chafing of the flexible tube almost all
the pipes and tubes are covered with some suitable non heat conducting material.
Cocks, taps, or valves are introduced at suitable points in the course of the pipes
or tubes to regulate or entirely cut off the supply of steam, water or fluid as may be
desired.
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,
The apparatus for conveying steam or liquid from a stationary supply to the cups
of gasholders at the varying altitudes, as herein described and shown on the
drawings.
