PROVISIONAL SPECIFICATION.
Improvements in the Construction of Fireproof and other Metal
Buildings.
We, CHARLES PEGRAM of 127 Brighton Road, Moseley, in the County of
Worcester, Manufacturer, and OWEN PERCY PARSONS, of Victoria Chambers,
Martineau Street, in the City of Birmingham, Architect and Surveyor, do hereby
declare the nature of this invention to be as follows:-
This invention has reference to the manner in which we construct and arrange
fireproof and other metal roofs, the object of our invention being to produce a
substantial roof which can be readily erected and taken down and which can also
be packed in a small space for transit.
In carrying our invention into effect when constructing a fireproof roof we make
the principals of metal plate or bars which we join together by bolts and rivets in
the ordinary manner to produce the desired configuration, each principal or complete
member being made up as one frame which we tie or attach to the vertical supports
or columns by means of curved or other webs or plates which we carry from the
main members to the vertical supports or columns. These vertical supports we
make of ordinary bar, angle or other section iron or steel plates at suitable intervals
to suit the distance apart or pitch of the main principals. We tie each principal
to its neighbour by means of a bolt running from one portion of the frame to the
other, the bolt preferably being shouldered down and having a nut at the recessed
end for screwing the same up closely against its shoulder and having a nut on the
other end for screwing also. We place these bolts or tie rods at any desired
distance apart to stiffen the frame and we arrange them so that they may break
joint or alternate one with the other when making up the roof having a large
number of principals the whole of which are tied together by our system of bolting
as herein before described. The over-hanging portion of our principals which
projects beyond the vertical support or pillar we tie to the vertical supports by
means of the continuing of the plate or by means of an independent plate or bar
which we run from one portion to the other and we carry the gutter upon the
projecting end by means of a T iron or by any other convenient bar which may
run from one member to the other, or we form the guttering with a T shaped back,
and we make provision by means of a recess in the plate for the web of the T to
enter, thus making a firm attachment upon each of the principals.
+
We tile our roof by means of splayed angle irons which we place within recesses
or grooves formed upon or cut within the members of the framework so that they
run from one to the other as a series of bars or supporting members to which the tiles .
may hook or may be attached by their lips or any other ordinary manner; the side
framework of our roofing we arrange in the same manner to receive splayed or
other angle iron or bars for sheeting the sides, the sheets being arranged or the
tiles being arranged to hang upon these splayed angles running from one vertical
support to the other.
By this our improved method of covering our roofs we are enabled to slip the
supporting angles within the frames from one end or to place them into the sides
or grooves by making the mouths or outer openings of the grooves wide enough for
them to be slipped in edge-ways from the top, thus making a convenient and simple
form of roof easily attached and easily erected and when taken down convenient
for transit by reason of the small space which it will occupy. We modify the

page_text: shape and configuration of our principals together with the method of jointing them
up to the uprights and the configuration of the same to suit any particular
requirement.

Improvements in the Construction of Fireproof and other Metal
Buildings.
We, CHARLES PEGRAM, of 127 Brighton Road, Moseley, in the County of
Worcester, Manufacturer, and OWEN PERCY PARSONS, of Victoria Chambers,
Martineau Street, in the City of Birmingham, Architect and Surveyor, 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 :-
&
This invention has reference to the manner in which we construct and arrange
fireproof and other metal roofs, the object of our invention being to produce
substantial roof which can be readily erected and taken down and which can also
be packed in a small space for transit.
In the accompanying sheets of explanatory drawings---
Figure 1 is a sectional elevation with the roof in perspective of our improved
system of construction: and
Figure 1B is a detail plan on the line a-b Figure 1.
Figure 2 is a perspective elevation of the principals and rafters.
Figure 3 is a detail elevation of an alternative arrangement of the roof tiles, and
Figure 1 is an enlarged detail elevation of a portion of our roof and side
members.
In carrying our invention into effect when constructing a fireproof roof, we make
the principals of metal plate or bars A which we join together by bolts and rivets
in the ordinary manner to produce the desired configuration, each principal or
complete member being made up as one frame which we build into or tie or attach
to the vertical supports B or columns by means of curved or other webs or plates C
which we carry from the main members to the vertical piers supports or columns.
These vertical supports we make of ordinary bar, angle or other section iron or
steel plates at suitable intervals to suit the distance apart or pitch of the main
principals, or we may employ brick or masonry or timber supports. We tie each
principal A to its neighbour A¹ by means of a bolt D running from one portion of
the frame to the other, the bolt preferably being shouldered down and having a
nut at the recessed end for screwing the same up closely against its shoulder and
having a nut on the other end for screwing also. We place these bolts or tie rods
at any desired distance apart to stiffen the frame and we arrange them so that they
may break joint or alternate one with the other when making up the roof having
large number of principals, the whole of which are tied together by our system of
bolting as herein before described. The over-hanging portion of our principals A³
which projects beyond the vertical support or pillar B we tie to the vertical supports
by means of the continuing of the plate or by means of an independent plate or
bar E which we run from one portion to the other, and we carry the gutter F upon
the projecting end by means of a T iron or by any other convenient bar which may
run from one member to the other or we form the guttering with a T shaped back
and we make provision by means of a recess in the plate for the web of the T to
enter thus making a firm attachment upon each of the principals.

page_text: We tile our roof by means of splayed angle irons or angle steel bars G H which
we place within recesses or grooves g h formed upon or cut within the members of
the framework so that they run from one to the other as a series of bars or
supporting members to which the tiles K may hook or may be attached by their
lips or any other ordinary manner. The side framework L of our roofing we
arrange in the same manner to receive splayed or other angle iron or bars M for
sheeting or covering the sides, the sheets being attached to these bars or the tiles N
being arranged to hang upon these splayed angles running from one vertical
support to the other.
We cover our vertical or central supports by means of a
ridge tile O.
By this our improved method of covering our roofs we are enabled to slip the
supporting angles or bars G H M within the frames from one end or to place them
into the sides or grooves by making the mouths or outer openings of the grooves
wide enough for them to be slipped in edge-ways from the top, thus making a
convenient and simple form of roof easily attached and easily erected and when
taken down convenient for transit by reason of the small space which it will occupy.
We modify the shape and configuration of our principals together with the method
of jointing them up to the uprights, columns or walls, and we vary the configuration
of the same to suit any particular requirement.
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 improved general arrangement of metal roof with side frames suitable
for receiving tiles or covering sheeting substantially as and for the purposes
herein before described and as illustrated in the accompanying drawings.
2. In a metal roof principal the arrangement of grooves or channels for receiving
the tile or sheet supporting bars substantially as and for the purposes hereinbefore
described and as illustrated in the accompanying drawings.
3. In a metal side frame or member for supporting a roof the arrangement of
grooves or channels for receiving the tile or sheet supporting bars substantially as
and for the purposes herein before described and as illustrated in the accompanying
drawings.
