PROVISIONAL SPECIFICATION.
Improvements in the Guide Framing of 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 for its object the construction of the guide framing of gasholders
in such a manner that it shall possess great rigidity and strength proportionate to the
various strains each part may have to bear.
I make the framing in one of two ways analogous to each other. According to the
first arrangement I make the framing concentric to the gasholder and of two or more
series of wrought iron, steel, or other suitable metal girders, crossing and being fixed
to each other at the points of intersection. Each line of each series of girders is curved
so as to partly encircle the gasholder, and in so doing to form a portion of a spiral, the
broad surface of the girder being placed diagonally to the horizon, the whole forming
a cylindrical network of girders. In the second arrangement instead of making the
framing circular in plan 1 make it polygonal, each side of the polygon being formed
of a series of straight girders placed diagonally to the horizon with vertical girders
placed at suitable intervals. In both arrangements the end of each line of girders is
fixed at top to a special girder or girders preferably of the "box" form, while the
lower ends of the girders are fastened by holding down bolts either to the tank, piers,
or other bases, or they may be secured to a girder of a similar character to
that at the top, so that the holding down bolts can be placed at more frequent
intervals, and thus distribute the strain over the tank or other foundations. The
guides for the rollers of the gasholder are fixed vertically to the top, bottom, and
intermediate girders and may or may not be constructed so as to form part of the net-
work of girders herein before described. It is obvious that in some of the details my
improved construction may be niodified but by constructing guide framing in
accordance with the foregoing description, the advantages before mentioned may be
ensured.

COMPLETE SPECIFICATION.
Improvements in the Guide Framing of Gasholders.
I, 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 for its object the construction of the guide framing of gasholders
in such a manner that it shall possess great rigidity, and strength proportionate to the
various strains each part may have to bear.
I make the framing in one of two ways, analogous to each other. According to the
first arrangement I make the framing concentric to the gasholder and of two or more
series A and B Fig. 1, of wrought iron steel, or other suitable metal girders, crossing
and being fixed to each other at the points of intersection C, C,-Each line of each
series of girders is curved so as to partly encircle the gasholder, and in so doing to
form a portion of a spiral, the broad surface of the girder, as shown at D. D, being
placed diagonally to the horizon, the whole forming a cylindrical network of girders.
In the second arrangement as exhibited in Fig. 2 instead of making the framing
circular in plan I make it polygonal, which having regard to economy of manufacture
Priced 1

series of straight girders E, E, placed diagonally to the horizon, with vertical
girders F placed at suitable intervals. In both arrangements the end of each line
of girders is fixed at top to a special girder or girders G, G, preferably of the box
form, while the lower ends of the girders are fastened by holding-down bolts either
to the tanks, piers, or other bases, or they may be secured to a girder of a similar
character to that at the top, so that the holding-down bolts can be placed at more
frequent intervals and thus distribute the strain over the tank or other foundations.
The guides H, H, for the rollers of the gasholder in both Figs. 1 and 2 are fixed
vertically to the top, bottom, and intermediate girders, and are in some cases con-
structed so as to form part of the network of girders hereinbefore described, but
though advantageous this connected construction is not essential. It is obvious that
in some of the details my improved construction may be modified, but by constructing
guide framing in accordance with the foregoing description, the advantages before
mentioned may be ensured.
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. The construction of the guide framing of gasholders with two or more series
of curved girders crossing each other and fastened together at the points of inter-
section, as herein described and shown on the drawing Fig. 1, and
2. The construction of the guide framing of gasholders with two or more series of
straight girders crossing each other and fastened together at the points of intersection,
as herein described and shown on the drawing Fig. 2.
