Improved Means or Appliance for Guiding Gasholders.
We, EDWARD LLOYD PEASE and ASHMORE BENSON PEASE AND COMPANY,
LIMITED, both of the Parkfield Works, Stockton-on-Tees, in the County of
Durham, Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the means or appliance for guiding gasholders and is
adapted to be used in connection with the vertical columns or standards which
constitute the ordinary guide framing where guide framing is not dispensed
with.
The invention is more particularly applicable when two or more lifts rise above
the height of the columns, the object being to ensure the proper engagement of
the radial carriages on the holder with the column guides when they return to the
level at which such engagement should take place.
As at present constructed the ordinary carriages disengage themselves from the
column guides as the holder is inflated and re-engage therewith as best they can
when the holder again lowers down to the level at which such re-engagement
should take place, the unaided stability of the lifts which so rise above the
columns being relied on to effect this.
By this invention we make the following provision to ensure the object in view:
A carriage constructed in two parts is fixed on each column or standard in such
a manner that the radial rollers of the holder and their goose neck carriages cin
pass up between the sides of these additional carriages each of which is furnished
with a roller, which rollers are set to an angle relatively to each other and for the
purposes of 83 metry converge equally towards the radial line of the holder
extending midway between the two sides of the carriage on the column, but in
practice the essential point is that these rollers engage with a combined direct
thrust and side thrust with the correspondingly bevelled edges of a vertical guide
plate secured in position on the outside of the lift of the holder to be guided,
which lift has its stability or vertical position ensured by means of these extra
guides and rollers when its ordinary guiding or gooseneck carriages are carried
above the line of contact with the columns so that these ordinary or usual rollers
and guides re-engage with accuracy when the holder returns to the proper
position.
The arrangement as described may be modified in its construction, in which a
single roller is mounted on a frame attached to the column at its upper part to
run in a groove on or secured to the opposite part of the holder, but to one side
of the ordinary radial roller in the goose neck frame.
The single roller in this case acts as a radial roller against the holder and does
the duty of the two rollers as described in the first arrangement.

We, EDWARD LLOYD PEASE, and ASHMORE, BENSON, PEASE AND COMPANY,
LIMITED, both of the Parkfield Works, Stockton-on-Tees, in the County of
Durham, Engineers, 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 relates to the means or appliance for guiding gasholders and is
adapted to be used in connection with the vertical columns or standards which
constitute the ordinary guide framing where guide framing is not entirely dispensed
with.
The invention is more particularly applicable when two or more lifts rise above
the height of the columns, the object being to ensure the proper engagement of the
radial carriages on the holder with the column guides when they return to the
level at which such engagement should take place.
As at present constructed the ordinary carriages disengage themselves from
the column guides as the holder is inflated to a greater height than the height of
the columns and re-engage therewith as best they can when the holder again
lowers down to the level at which such re-engagement should take place, the
unaided stability of the lifts which so rise above the columns being relied on to
effect this; and when one lift only rises above the columu guides, the risk of
fouling when the holder lowers is not great. But when two lifts are required to
rise above the column guides, means for guiding the lower lift in the manner of
this invention is indispensable.
And in order that our invention may be clearly understood and readily carried
into effect, we will now proceed to describe the same with reference to the drawing
hereto annexed, in which Fig. 1. illustrates in outline a part sectional elevation of
a four-lift gasholder with the two inner lifts guided when they rise above the
height of the columns in accordance with our invention. Fig. 2. is an enlarged
plan view of same; and Fig. 3. is an enlarged plan view illustrating a modification
of our invention.
Referring to Fige. 1 and 2, a carriage a constructed in two parts is fixed on each
column or standard b in the manner shown so that the radial rollers c of the
holder and their goose-neck carriages d, can pass up between the sides of these
additional carriages a, each of which is furnished with a roller e, which rollers are
set to an angle relatively to each other and for the purposes of symetry converge
equally towards the radial line of the holder extending midway between the two
sides of the carriage a on the column, but in practice the essential point is that
these rollers engage with a combined direct thrust and side thrust with the
correspondingly bevelled edges of a vertical guide plate secured in position on
the outside or wall of the lift of the holder to be guided which in this case is the
second inner lift, which lift has its stability or vertical position ensured by means
of these extra guides f and rollers e when its ordinary guiding or goose-neck
carriages d are carried above the line of contact with the columns so that these
ordinary or usual rollers c and guides re-engage with accuracy when the holder
returns to the proper position or level at which this should take place. The
roller or rollers e carried on the columns will engage with the guide on the
holder which may be of various forms, either on one or both sides of the carriage
on the holder itself, and the rollers may be radial or tangential or at any angle.
These duplicate rollers secure the true engagement of the rollers in the roller
paths and in this manner render it safe to allow two lifts to rise above the columus
instead of only one. This is of use either in adding lifts to existing holders, or

page_text: in the construction of, for example, a three-lift holder in which the columns would
be made to the height of the outer lift only.
Referring to Fig. 3, the arrangement as herein before described may be modified
in its construction, in which a single roller el is mounted on a frame a¹ attached to
the column b at its upper part to run in a groove f¹ on or secured to the opposite
part of the bolder, but to one side of the ordinary radial roller c in the goose-neck
frame d. The single roller el in this case acts practically as a radial roller against
the holder and takes the place of the two rollers e e as described with reference to
Figs. 1 and 2.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In combination with gasholders in which the holder is inflated above the
height of the columns the use of additional guiding appliances adapted to ensure
the proper re-engagement of the carriages on the holder with the guides on the
columns when the holder returns to the level at which such re-engagement should
take place, the said additional guiding appliances being arranged and operating
substantially as hereinbefore described with reference to the accompanying
drawing.
2. The combination of parts as a whole, constructed, combined and operating
together, substantially as and for the purpose herein before described with reference
to the accompanying drawing.
