Tee, or other Form of Iron Supports.
We, FRANCIS MORTON, of Victoria Chambers, Westminster, Director of Francis
Morton & Co. Limited of Liverpool, and GEORGE TAYLOR of Francis Morton & Co.
Limited of Liverpool, Works Manager, do hereby declare the nature of this inven-
tion to be as follows:-
The object of our invention is to provide a cheap and efficient fastening for
securing corrugated or flat sheet metal, preferably to angle or other iron supports
without its being necessary to bore holes into such angle or other iron.
Screw bolts with a hook bend at one end and a screw thread at the other end for
a nut to be screwed on to, have before been used for the purpose. The hook has
been hooked over the edge of one flange of the angle or other iron, the stem has
passed across this flange and through a hole in a corrugated or flat sheet placed
against the other flange and a nnt has then been screwed on to the screw stem to
hold all together. One objection to this fastening is that the screw bolts have to be
specially shaped by forging or bending, another that by this method the nut is
brought on the outside of the structure, thus enabling its ready removal.
We use an ordinary straight screw bolt or in some cases with the stem bent to
the shape of the iron it is to pass over with a head at one end, and a screw thread cut
on the other end, and with it we use a thick nut or washer so shaped as to hook over
and fit to one edge of the angle or other shape iron, and to project out from the angle
or other shape iron sufficiently for the screw stem of the bolt to pass or screw through
it. The stem of the bolt is first passed through a hole in the flat or corrugated plate,
it then passes across the side of the angle or other shape iron which stands out from
the back of this plate then passes or is screwed through one of the washers which is
hooked over the edge of this side and then has an ordinary screw nut screwed on to it,
thereby holding or locking as the case may be, the washer tightly against the edge of
the angle, tee or other shape iron. .

page_text: The nuts or washers formed to fit over the edge of the angle iron may readily be
made of malleable cast iron or other metal. wrought or cast and at small cost.
In some cases more especially for securing roof sheeting to iron purlins where it is
often inconvenient to have the nuts on the inside owing to the difficulty of getting to
them to screw them up unless a scaffolding is erected the position of the washer clip
may be reversed and the washer placed against the head of the bolt so that the nut
may be screwed on to the screwed end of the bolt as now is the case when using
ordinary hook bolts.

Improvements in Fastenings for Securing Sheet Metal to Angle,
Tee, or other Form of Iron Supports.
We, FRANCIS MORTON of Victoria Chambers Westminster Director of Francis
Morton & Co. Limited of Liverpool and GEORGE TAYLOR of Francis Morton & Co.
Limited of Liverpool Works Manager 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 cheap and efficient fastening for securing
corrugated or flat sheet metal, preferably to angle or other iron supports without its
being necessary to bore holes into such angle or other iron.
Screw bolts with a hook bend at one end and a screw thread at the other end for a
nut to be screwed on to, have before been used for the purpose. The hook has been
hooked over the edge of one flange of the angle or other iron the stem has passed
across this flange and through a hole in a corrugated or flat sheet placed against the
other flange and a nut has then been screwed on to the screw stem to hold all together.
One objection to this fastening is that the screw bolts have to be specially shaped by
forging or bending another that by this method the nut is brought on the outside of
the structure thus enabling its ready removal.
We use an ordinary straight screw bolt or in some cases with the stem bent to the
shape of the iron it is to pass over with a head at one end and a screw thread out on
the other end, and with it we use a thick nut or washer so shaped as to hook over and
fit to one edge of the angle or other shape iron and to project out from the angle or
other shape iron sufficiently for the screw stem of the bolt to pass or screw through it.
The stem of the bolt is first passed through a hole in the flat or corrugated plate, it
then passes across the side of the angle or other shape iron which stands out from the
back of this plate then passes or is screwed through one of the washers which is hooked
over the edge of this side and then has an ordinary screw nut screwed on to it thereby
holding or locking as the case may be, the washer tightly against the edge of the
angle, tee or other shape iron.
The nuts or washers formed to fit over the edge of the angle iron may readily be
made of malleable cast iron or other metal wrought or cast and at small cost.
In some cases more especially for securing roof sheeting to iron purlins where it is
often inconvenient to have the nuts on the inside owing to the difficulty of getting to
them to screw them up unless a scaffolding is erected the position of the washer
clip may be reversed and the washer placed against the head of the bolt so that the
nut may be screwed on to the screwed end of the bolt as now is the case when using
ordinary hook bolts.
In order that our said invention may be fully understood and readily carried into
effect we will proceed to describe the drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a plan of a portion of the side of a structure consisting of corrugated
iron sheets secured to angle iron supports.
Figure 2 is an inside elevation of the same and-
Figure 3 is a vertical section.
a is the angle iron support, b is the corrugated iron sheet.
c is the fastening bolt, it may have a head of any suitable form, the head c¹ is here
shown as adapted to receive a screw driver by which it can be turned or held from
turning.
d is a hook piece made to engage with the edge of the angle iron or other support.
e is a nut screwed on to the bolt beyond the hook piece d. This piece d may have a
screw. thread cut in it to engage with the thread upon the bolt-the nut e then operates
as a lock, and it prevents the bolt being turned from the outside. When this pre-
caution is unnecessary the nut may be omitted. In most cases it will suffice that the
piece d should pass freely on to the bolt and that the nut e should be screwed on
beyond. Where nuts on the inner side would be difficult of access and where there is
no risk of their being tampered with if placed outside, we may pass the bolt through
the piece d from within so that the head c¹ comes against the piece d, the nut then is
applied on the outside and comes against the corrugated iron b. As before mentioned
it is not essential that the sheets b should be corrugated. Sometimes the face of the
support against which the stem of the bolt c lies may be convex in place of flat and
then the stem of the bolt will be bent to a corresponding curve.
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. The combination substantially as described consisting of the angle iron or other
support a the corrugated iron or other sheet b, the fastening bolt c with its head c
retaining the sheet 6 in place against the support, and the hook piece d engaging with
the edge of the support a and secured to the bolt either by screwing upon it or by a
nut or both.
2. Fastenings substantially as described for securing sheet metal to augle tee or
other form of iron supports.
