Method of Fire Proofing Columns, Stanchions, Girders (Iron or
Steel), Ceilings, Walls, Flooring, or Buildings in any Position.
I FRANCIS PILKINGTON 41 Redhill Street Regents Park N.W. Iron Merchant
do hereby declare the nature of this invention to be as follows, viz. :—
I propose to mould and make Tiles Bricks Blocks or Pieces composed of any Fire
Proof material or of Wood-mould and make in segments of a circle to fit and follow
closely the circumference of Columns and fitted together with Tongue and Groove
Joint ends of such Tiles Bricks Blocks or Pieces may be bevilled. On inner side of
such Pieces I cast or make a Loop or Key-way and on the column I cast or make
corresponding attachments or Keying Irons to securely hold in position.
In Fire-Proofing Stanchions Girders Ceilings-Walls Flooring or Buildings
I follow the Principle of the fastening by Tongue & Groove Joint-Key-way
& Keying attachment-making the material of such size and shape best adapted to
position required.

I, FRANCIS PILKINGTON, of 41 Redhill Street, N.W. in the County of Middlesex,
Iron Merchant, 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 :-
I
propose to mould and make tiles bricks blocks or pieces or the like composed of
any fire proof material or of wood mould and make in segments of a circle to fit and
follow closely the circumference of columns and the like and fitted together with
tongue and groove or any other description of joint the ends of such said tiles bricks
blocks or pieces may be bevelled. On the inner side of such pieces I cast or make
a loop or key way and on the column I cast or make corresponding attachments or
keying irons to securely bold the said tiles bricks or the like in position. In fire
proofing stanchions girders ceilings walls flooring or buildings I follow the principle
of the fastening by tongue and groove joint key way and attachment making the
Diaterial of such size and shape best adapted to the position required. The object of
my invention is to fire proof columns stanchions girders in iron or steel ceilings walls
flooring or buildings in any position by means herein before described and in following
out my invention I employ always the principle of fastening by key way and keying
attachment tongue and groove joint or bevelled ends applying the same in such
combinations according to the nature of the work and the position that is required.
And in order that my invention may be thoroughly understood I now proceed to
describe the accompanying drawings thereof reference being had to letters and
figures marked thereon. Figure 1 denotes a system of fire proofing by arches in
brick on concrete or other like material marked C turned on the girders marked A. A.
with a key stone in the centre or crown of the arch marked D with tongues F. F.
the key stone running the whole or part of the length of the arch constructed of stone
concrete block or other like material this said key being held up by a loop or an iron
rod or key stay E fixed to the upper side of the key D and bolted to railway, tee,
channel flat or other shaped iron B running along the top flanges of the girders A. A.
or through the webs of the joists or girders and carried from wall to wall and
composed of such size and shape I may deem necessary and securely attached the
said bar to the loop or key stay. Figure 2 represents an iron column G with the
attachment I. fitted into the slots O of the tiles H with the tongue L fitted into a
groove N with the recess J being the fixing position of the tile for head of the
attachment I fixed to the column the top and bottom of the tiles being bevelled off at
any angle. Figure 3 represents an enlarged section of the tile on line, a. b.
Figure 4 the back view of the tile. Figure 5 a section of the tile on line, c. d.
Figure 6 is a section fire proof floor composed of iron or steel joists A with concrete C.
or the like material and i employ the method of keying E together the top bottom

page_text: tee or any other shaped iron B and filling the whole in with concrete or other like
material supported on the walls marked P. P. Figure 7 is a section of a fire proof
floor composed of wood joists Q of any depth or thickness joined closely together and
through them I run a bar of round or flat iron R screwed at both ends V with
nuts W. and washers to bolt the whole tightly together the bolt is secured in the
centre by a tie or keying stay E fixed to the bar of iron or steel of any size or shape B
and thereto securely fix keying stay. To make a fire proof ceiling by this method
I fix narrow bands of metal beneath joists and screwed thereto with keying attach-
ments and thereto I fasten securely the fire proofing tiles by means of the loop or key
way made therein for such purposes. In fire proofing walls I follow the same method
of attaching narrow strips of metal with similar attachments, as hereinbefore described.
Like letters refer to like parts in each of the figures. A the joists. B the railway,

Having now fully described the nature and object of my invention and the
manner in which the same is to be performed I claim as new and novel the
following
--
First: The combination of the application of key way and keying attachments
substantially herein described and according to the accompanying drawings.
Secondly: The combination of the application of tiles made in segments of a circle
for columns or any other shape for stanchions substantially herein described and
according to the accompanying drawings.
:
Thirdly The combination of the application of tongued blocks in stone concrete
iron or any other material for forming centre keying to arches substantially herein
described and according to the accompanying drawings.
Dated this 20th day of December 1887.
