Improvements in the Construction of Fire-resisting Partitions and
Walls in Buildings.
We JOHN WILSON of 13 Abbeville Road North, Clapham in the County of Surrey
Constructional Engineer, JOHN BERRY TORR of 340 Wandsworth Road Clapham in
the County of Surrey Engineer and JOSEPH WENTWORTH of 44 St. Johns Wool in
the County of Middlesex Engineer do hereby declare the nature of our said invention
to be as follows:-
The object of our invention is to provide a method of constructing partitions walls
and the like in buildings so that they shall have extreme fire-resisting power with a
minimum of weight and at the same time if required a tendency to prevent the
transmission of sound.
According to our invention we use rolled joists or girders of double Ṭ section and
on the planes of these vertically and at right angles thereto we attach T iron uprights
or supports the web of these are cut away near the ends thereof and the said ends are
bent or forged in a L form so as to permit of their being bolted or otherwise attached
to the flanges aforesaid.
The said Tirons are placed either in the centre of the partitions or alternately on
either side of the joist or girder as preferred.
We then bolt or attach to the backs of the said T irons flat iron connections at
suitable intervals or heights the whole is then filled in incased or surrounded with
concrete by means of the usual centering or boarding.
In place of the flat connecting irons or of the before mentioned general construction
we may form slabs or panels of concrete in moulds or otherwise and fit or attach them
within or to the flanges of the upright Tirons said slabs forming the whole thickness
of the partition.
Spaces cavities or the like may be cast or formed in the said slabs of concrete to
prevent the transmission of sound.

Improvements in the Construction of Fire-resisting Partitions and
Walls in Buildings.
We JOHN WILSON of 13 Abbeville Road North, Clapham in the County of Surrey
Constructional Engineer, JOHN BERRY TORR of 340 Wandsworth Road Clapham in
the County of Surrey Engineer and JOSEPH WENTWORTH of 44 St. Johns Wood 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 :-
The object of our invention is to provide a method of constructing partitions walls
and the like in buildings so that they shall have extreme fire resisting power with a
minimum of weight and at the same time if required a tendency to prevent the
transmission of sound.
According to our invention we may use rolled joists or girders of double T section
and on the planes of these vertically and at right angles thereto we attach T irons
uprights or supports the webs of these are cut away near the ends thereof and the said
ends are bent or forged into a L form so as to permit of their being bolted or other-
wise attached to the flanges aforesaid.

page_text: The said Tirons are placed either in the centre of the partition or alternately on
either side of joist or girder as preferred, or we may place two of these T irons back
to back, thus or may use in place iron of + section.
We then bolt or attach to the backs or webs of said T or irons flat iron con-
nections at suitable intervals or heights the whole is then filled in incased or surrounded
with concrete by means of the usual centreing or boarding.
"
In place of the flat connecting irons or of the before mentioned general construction
we may form slabs or panels of concrete in moulds or otherwise and fit or attach them
within or to the flanges of the upright irons said slabs forming the whole thickness of
the partition. Spaces cavities or the like may be cast or formed in the said slabs of
concrete to prevent the transmission of sound.
Referring to the accompanying sheet of drawings-
Figure 1 shows an elevation of our arrangement of T iron uprights and horizontal
bars before being surrounded by or embedded in concrete or the like A being a beam
or girder on which are secured the vertical T or other sectional irons B to which are
attached horizontal bars or plates C.
Figure 2 is a sectional plan of a wall or partition constructed according to our
invention D representing the concrete filling.
Figure 3 is a vertical section of a partition on line a band
Figure 4 a similar section on line c d in Figure 2.
Figure 5 is a view of a block or slab of concrete formed so as to be readily fixed in
position between vertical + irons and having a groove or grooves E E therein for the
purpose of engaging with the vertical irons and being retained in position thereby and
so forming the body of the wall or partition it being only necessary to plaster or
cement over the whole; the grooves are cut away in portions F F (as shown by dotted
lines) so as to allow of the slabs slipping easily into their places; G G are the cavities
or spaces which may be formed in the slabs or in the concrete filling.
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 fire resisting constructions the formation of vertical partitions or walls
composed of Tor + iron supports carrying horizontal bars or the like the whole
surrounded by concrete or suitable composition substantially as herein described and
illustrated by Figures 1, 2, 3 and 4 in the accompanying drawings.
2. In fire resisting constructions the use of a concrete or like block or slab having
grooves E on the vertical edges to engage with the flanged portions of vertical
uprights such as B the said grooves being cut away or splanged as at F F to enable
the blocks to be readily adjusted in position substantially as described and illustrated
herein.
3. The specially arranged construction of fire resisting partitions or walls sub-
stantially as herein described and illustrated.
