PROVISIONAL SPECIFICATION.
Improvements in the Mode of and Means for Forming Partitions,
Ceilings, Roofs, and Floors.
I ARTHUR OCTAVIUS WRIGHT of 39 St. John's Road Birmingham in the County
of Worcester Manufacturer do hereby declare the nature of my said invention to be
as follows:-
:-
My invention has for its object improvements in the mode of and means for
forming partitions ceilings roofs and floors which are fire resisting and of great
strength and stability while the whole can be readily erected in a simple cheap and
effective manner.
In carrying my invention into effect I use iron or other metal sheets which I
corrugate by first passing through one machine having a pair of jaws which operate
upon it so as to give it a zigzag corrugation after which the sheets are passed
through a second machine having another pair of jaws which so operate upon the
sheets as to convert the zigzag corrugations into dovetail corrugations. In feeding
in the partly corrugated sheets into the second machine I provide an arrangement
of shaped rolls which engage with the corrugation and feed in the metal to the
machine. In using these specially corrugated sheets and for firmly fixing them
with the least possible expense I use lengths of iron rafter joints or standards
of H section so arranged that the ends of the corrugations just slide into the grooves
of the H section and these rafter joists or standards are fixed by being inserted in
slots formed in the timber framing or in the case of large spans may be fitted into
specially slotted girders.
The framework thus formed is then coated with plastic material the dovetail
corrugation in the sheets forming a perfect key for retaining the plastic material in
position. The plastic material may vary to suit the particular requirements of the
case as for instance in the case of roof it may be neat cement while in the case of
partitions it may be plastered floated and set in the usual manner.

Improvements in the Mode of and Means for Forming Partitions,
Ceilings, Roofs, and Floors.
I, ARTHUR OCTAVIUS WRIGHT of 39 St. John's Road, Birmingham, in the County
of Worcester, Manufacturer do hereby declare, the nature of my said 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 has for its object improvements in the mode of and means for
forming partitions ceilings, roofs, and floors, which are fire resisting and of great
strength and stability, while the whole can be readily erected in a simple, cheap
and effective manner.
In carrying my invention into effect I use iron or other metal sheets, which are
corrugated by first passing through one machine having a pair of jaws which
operate upon it so as to give it a zigzag corrugation after which the sheets are
passed through a second machine having another pair of jaws, which so operate
upon the sheets as to convert the zig-zag corrugations into dovetail corrugations.

page_text: In feeding in the partly corrugated sheets into the second machine, I provide an
arrangement of shaped rolls which engage with the corrugation and feed in the
metal to the machine. In using these specially corrugated sheets and for firmly
fixing them with the least possible expense, I use lengths of iron rafters, joists or
standards of H section, so arranged that the ends of the corrugations slide into the
grooves of the H section and these rafters, joists or standards are fixed by being
inserted in slots formed in the timber framing or in the case of large spans, may be
fitted into specially slotted girders. One or two channel bars may be used instead
of the H section.
The framework thus formed is then coated with plastic material, the dovetail
corrugations in the sheets, forming a perfect key for retaining the plastic material
in position. The plastic material may vary to suit the particular requirements
of the case as for instance, in the case of roofs, it may be cemented, while in the case
of, partitions it may be plastered floated, and set in the usual manner.
In order that my invention may be clearly understood, and more easily carried
into practise, I have appended hereunto a double sized sheet of drawings upon which
I have fully illustrated the nature of my said improvements.
Figure 1 is a section showing the dovetail grooved sheet in section.
Figure 2 is a cross section through the feed of the machine for producing these
sheets showing my improvements embodied thereto.
Figure 3 is a plan of same.
Figure 4 shows my particular mode of constructing partitions, as will be hereafter
described.
Figure 5 is a section of H girder specially constructed for use in my partitions or
floors.
In carrying my invention into effect, the sheets which are corrugated by first
passing through a machine having a pair of jaws similar to those shown by Y and Y'
Figure 2, which are operated by levers y² thus giving the sheet the zigzag
corrugations, as seen entering the feed of Figure 2 after which it is operated upon
by the jaws Y and Y¹ being thus converted into the dovetail corrugated shape, as
shown emanating from the machine in Figure 2., the important feature of which is
the feed rolls R and R' for feeding in the zigzag corrugated sheets for the final
operation the sheet moving from left to right. The top roller R¹ is mounted so as
to be capable of being raised and thus allow the sheet to be drawn sharply forward
which is effected by the action of the jaw Y' as it forms each dovetail, this being
effected by means of the cam S upon the shaft s¹ which operates the lever and
through the rod s³ raises the roll and retains it there a sufficient time to allow the
sheet to be drawn forward. The two rolls are geared together by cog wheels
which have teeth a sufficient length to enable the top roll to continue revolving
during the time the sheets are being drawn forward, and thus the two rolls continue
their movement in accurate relation to the sheets so that upon the lowering of the
roll R the two rolls are in position for feeding in the remainder of the lap
required before forming the next dovetail. The top roll is mounted in the guides s.
This feeding arrangement lessens considerably the amount of attention required for
feeding the sheets into the machine. In the case of corrugated iron sheets herein
described, I fix them so as to form partitions with the iron joists or standards W
which are of H or channel section, the size of the channel being so arranged that
the corrugations of the sheets fit and slide into the channel as shown at Figure 4 the
supports W being fixed by having their ends inserted in slots formed in the
supporting girders or standards X, the whole being afterwards coated with plastic
material thus retaining the plastic material in position.
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
1st. The combination and arrangement of mechanism and parts whereby sheets
of iron or other suitable material may be shaped with dovetail corrugations as

page_text: shewn in Figure 1 substantially as and for the purpose herein described and shewn
in the accompanying drawings Figures 2 and 3.
2nd. The constructions of partitions by means of dovetail sheets combined with
channel irons substantially such as herein set forth and as shewn by Figure 4 of the
drawings.
