PROVISIONAL SPECIFICATION.
Improved Method of Maintaining_Telescopio Gas Holders in their
Working Positions.
I, EDWARD LLOYD PEASE, Managing Director of Messrs. Ashmore Benson
Pease & Co. Ld. of Stockton on Tees, do hereby declare the nature of this
invention to be as follows:-
My invention refers to the use of wire ropes or equivalent in connection
with columns for the better maintaining of telescopic holders in their true working
position.
By this means, it is possible to make the sections or lifts of telescope gas
holders shallower in proportion to their depth than is possible when columns
alone are used, thus saving great expense in the construction of the tank and
holder.
The lower lifts are guided between columns in the usual manner, and the
upper lifts rise above the columns.
The proportion between the number of lifts that rise above the columns, and
those that do not, may be as desired.
Ropes three or more in number are led over the gasometer each from the top of
a column on one side to the ground level on the other side or thereabout. The
rope in each case is so connected with the gas holder that the descent of a section
or lift on the one side gives the amount of slack required to permit of a like descent
on the other side and vice versa. Not only are the sections or lifts which rise
above the columns controlled in this manner but also the lifts between the
columns.
There are various ways of fixing the pullies on the holder which may be
adopted.
I will describe by way of example an arrangement suitable for a five lift gaso
meter counting the sections from the ground upwards the columns guide the
sections 1, 2 and 3 and the sections 4 and 5 rise above the columns. The rope in
each case may be traced from its fixture at the top of the column down and around
a pulley on the top of section 3, then up and around a pulley on the top of
section 4, down beneath a pulley fixed at the bottom of section 5 up over a
pulley at the top of the same section, thence across the top of the gas holder to
another pulley at the top of section 5 down beneath a pulley at the foot of section 4,
over a pulley at the top of section 3 and thence down to its attachment at the
ground level.

Ropes three or more in number are led over the gasometer each from the
top of a column on one side to the ground level on the other side or thereabout.
The rope in each case is so connected with the gas holder that the descent of
a section or lift on the one side gives the amount of slack required to permit
of a like descent on the other side and vice versa. Not only are the sections or
lifts which rise above the columns controlled by this mechanism but also the lifts
between the columns.
There are various ways of fixing the pullies on the holder which may be
adopted.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation and Figure 2 is a plan of a telescopic gas holder which
is guided and controlled in accordance with my invention.
Figures 3 and 4 show parts of Figures 1 and 2 much enlarged.
Figure 5 shews a variation in the arrangement of the control ropes.
a¹ a² a a¹ and a' are the five sections or lifts of a telescopic gas holder, they are
connected by dip joints arranged in the ordinary way and as is seen in Figure 3.
bbbb are columns of which any suitable number may be provided ranged around
the gas holder; they furnish elevated points for the attachment of the control
ropes and they serve also in the usual way to guide the lower lifts of the gas
holder.
The upper lifts a* and a³ rise above the columns and are controlled only by the
ropes. In the arrangement shown four control ropes c¹³ ³ and care provided,
they are arranged in pairs which are in all respects similar; the one pair crosses
the other pair at right angles over the top of the gas holder; d d are guide pulleys
supporting the ropes in this part of their course. As represented in Figures 1 to 4
each rope may be traced from a point of attachment at the top of one of the
columns b beneath a pulley e on the top of the lift a which is the uppermost of the
lifts guided by the columns; thence up to the top of the gas holder and across to
the other side, then down under a pulley f' on the lower part of the highest lift a
and over a pulley on the top of the lift a', thence the rope passes in a similar
way over pulleys ƒ and g g on the lifts a* and a' respectively. The rope has now
again reached the lift a with which it first engaged and from this point it is led
down to the ground level at h where it is made fast at the foot of the column b.
The other rope of the pair takes a precisely similar course but passes in the opposite
direction starting from the top of the same column at which the other rope
terminates; this arrangement equalises the friction and other conditions on the two
sides of the gas holder.
In Figure 5 the control rope is shown arranged in a slightly different but
equivalent manner. Counting the lifts or sections from the ground upwards the
rope may be traced from its fixture at the top of the column, down and around a
pulley on the top of section 3, then up and around a pulley on the top of section 4
down beneath a pulley fixed at the bottom of section up over a pulley at the top
of the same section, thence across the top of the gas holder to another pulley at
the top of section 5 down beneath a pulley at the foot of section 4 over a pulley at
the top of section 3 and thence down to its attachment at the ground level.

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. A telescopic gas holder in which control ropes are employed in combination
with guiding columns substantially as described.
2. A telescopic gas holder substantially as represented by the annexed
drawings.
