page_text: I ARTHUR WILLIAM RAMMAGE, of 42 Old Broad Street, London, 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 :-
My invention relates to improvements in pillars used in building construction, and
the manner in which the said pillars are rendered fireproof, rigid, and prevented from
buckling.
I now proceed to describe my invention, reference being had to the accompanying
drawings, the figures and letters marked thereon, similar letters referring to similar
parts throughout.
Fig. 1 is an elevation of my improved pillar and stauncheon combined. Fig. 2 is
a part sectional elevation of my improved fireproof pillar and stauncheon combined.
Fig. 3 is a cross section through my improved fireproof pillar and stauncheon
combined. Fig. 4 is a cross section through my improved fireproof pillar and
stanchion combined shewing the manner in which said pillar as shewn in Fig. 3, may
be strengthened. Fig. 5 is a cross section through a modified form of my improved
fireproof pillar. Fig. 6 is a cross section through the modified form of my improved
fireproof pillar shewing the manner in which the said pillar as shewn in Fig. 5 may
be strengthened. Fig. 7 is a cross section through an alternative form of my
improved fireproof pillar. Fig. 8 is a cross section through the alternative form of
my improved fireproof pillar, as shewn in Fig. 7, shewing how the centre column may
be strengthened. Fig. 9 is a cross section through the alternative form of my
improved fireproof pillar shewing how the outer shell may be strengthened. Fig. 10

page_text: is a cross section through the alternative form of my improved pillar and stanchion
combined. Fig. 11 is a cross section through the alternative form of my improved
pillar and stanchion combined, shewing how the said pillar as shewn in Fig. 10 may
be strengthened.
The outer shell A of my improved fireproof pillar and stanchion combined, consists
of rolled steel plates A with flanges a which are rolled in one piece and in one
operation with said steel plates A, and by means of which flanges a, the said steel
plates A are rivetted together.
At suitable intervals along the outer shell A are placed suitable steel Tees, or steel
angles A, which serve as stiffeners and which are securely rivetted to the outer shell A
as shewn.
When the said outer shell A is of large diameter, it may be strengthened by
additional rolled quater cylindrical plates A, which may be of any required number
and thickness, and securely rivetted to the outer shell A.
Passed centrally from end to end of my improved fireproof pillar is a stauncheon B¹
(Figs. 3, 4, 10, 11) or inner pillars B³ (Figs. 5, 6, 7, 8, 9.) The stauncheon B
consists of steel angles rivetted together in combination with flat steel plates C which
when securely rivetted between the flanges a of the outer shell A, form a rigid stay
to the said outer shell A. The inner pillars B³ consist of rolled quarter steel plates
with flanges c which are rivetted together in combination with the steel plates C as
shewn, when it is desired to give additional strength to the inner pillars B³, additional
steel plates B2 of any required number and thickness may be securely rivetted to the
under shell, as shewn in Fig. 8.
The stanchions B' and inner pillars B³ are additionally stayed to the outer shell A, by
means of bolts D, provided with. nuts and washers, and which bolts are placed at
suitable intervals as shewn more clearly in Figs. 1 and 2.
The bases E and caps E¹ of my improved pillar and stauncheon combined may be
of any desired shape and size and are securely attached to the outer shell A of said
pillar by means of rivets passed through suitable steel angles e. The said bases E
and caps E' are provided with suitable stiffners E³, by means of which the weight is
evenly distributed upon the said pillar and base E. The base E may be securely
bolted down to the foundation stone H by means of suitable bolts passed through the
steel angles e as shewn.
The inside of the afore-described outer and inner pillars may be filled either with
concrete or cement, concrete and cement, or cement and asbestos, by means of
which concrete cement or asbestos, the said pillar is rendered both fireproof and
solid.
In order to take the weight of upper pillars and to carry various cross
beams, suitable boxes G are introduced, and which may be built up of steel
plates g and angles g¹ securely rivetted to the outer shell A of the pillar. The
said boxes are adapted to pass through the concrete flooring as shewn in
Figs. 1 and 2.
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 :-
:-
1st. In a fireproof pillar, the outside shell consisting of rolled steel quarter
cylindrical plates with flanges, or rolled steel plates with flanges, rivetted together in
combination with flat steel stays, substantially as, and for the purposes hereinbefore
described and fully illustrated in the drawings hereunto annexed.
2nd. In a fireproof pillar, a stanchion consisting of angle steel, or trough steel,
substantially as and for the purposes herein before described and fully illustrated in the
drawings hereunto annexed.
3rd. In a fireproof pillar an inner column consisting of rolled quarter cylindrical
steel plates with flanges, and means whereby said quarter cylindrical steel plates may
be strengthened, all substantially as, and for the purposes herein before described and
fully illustrated in the drawings hereunto annexed.

page_text: 4th. In a fireproof pillar, steel plates adapted to connect the central stauncheon or
inner pillar with the outer shell of said pillar, in combination with steel bolts
placed at intervals along said pillar substantially as and for the purposes hereinbefore
described and fully illustrated in the drawings hereunto annexed.
5th. In a fireproof pillar, the inner side of said pillar or inner pillar filled with
concrete or cement, or concrete and cement, or cement and asbestos substantially as,
and for the purposes hereinbefore described and illustrated in the drawings hereunto
annexed.
6th. In a fireproof pillar, the construction and general arrangement of my improved
pillar and stauncheon combined, for building construction, all substantially as, and for
the purposes herein before described, set forth in the claims, and fully illustrated in the
drawings hereunto annexed.
