CHANNEL ROOFING AND AWNING
Year: 1884

page_text: COMPLETE SPECIFICATION.
I EDWARD PATRICK GRIBBON, of N° 54 Harcourt Street Dublin, Architectural
& Engineering Surveyor, do hereby declare the nature of my Invention for
CHANNEL ROOFING AND AWNING and in what manner the same is to be performed,
to be particularly described and ascertained in and 'by the following statement, viz.:
It is a method of roofing and awning, with a combination of trough gutters or
channels, formning furrows, with ridges or substitutes for ridges between-all
capable of being made & kept ready for transport, & for fixing, and of being
rapidly fixed whenever shelter is hurriedly. required.
One of the chief objects of this Invention is its use as an improvement on
weather boarded and other roofs for shelter sheds, and as a substitute for tarpaulin
and other temporary awning over goods, or over men engaged on outdoor labor in
wet weather, or over animals, and of such construction as may be readily fixed for
temporary use, and again easily removed and refixed elsewhere.
"
In this roofing or awning as will be seen on the Drawing herewith the furrows
each consist of a pair of boards or planks standing on edge and acting as joists or
rafters, and these boards or planks form the sides of the furrow, and between
these sides a third board is fixed on flat, and jointed to the others, and the three-
boards or planks so joined together form the furrow in the nature of a channel or
trough or box gutter, as in Figures 1 and 4 on the accompanying Drawing, or the
bottom board is made wider at one edge, or at both edges to pass under the
upright boards (or under one of them) as in Figure 2, or the channels are formed
in solid timber hollowed out as in Figure 3.
The channels troughs or furrows are made of the same size at each end, or
smaller at one end and tapering in length, and of such sizes and scantlings &
thicknesses of materials as varying lengths or spans or circumstances may necessitate
or as users may desire, and may be made as strong as ordinary roofing or joisting
where strength is required.
In forming the channels as box gutters out of planks or boards the same may
be jointed together with plain joints or boused joints or with tongued or rebated.
or filleted joints or irrespective of any particular mode of jointing. The channels
or troughs are as a matter of choice lined with sheet lead or sheet iron or zinc
copper or other lining, & the ridges if desired covered with same or other covering,
or each or either or any of the ridges or furrows lined with calico or canvas
waterproofed or plain, or with other waterproofed or plain lining or covering, or

page_text: the furrows or ridges or both may be treated with any preserving process or used
bare, or painted or coated with tar or other coating.
The channels troughs or furrows are fixed or placed side by side close together
or nearly so as in Figure 1, or with spaces between as in Figure 5, and inverted
channels or troughs of similar or different shapes and sizes or any substitute for
same cover the joints or spaces between the furrows and form the ridges, or where
sheet iron (or other lining fit for the purpose) is used in the channels it may be of
additional width to overlap the side or sides of the next channel or channels and'
to act as a substitute for ridges, or separate ridges may be used of sheet iron or
zinė or other material, also sheet iron or common channel bar iron or specially
made channel iron may be used for the furrows as a substitute for timber, and the
channels or furrows may in either case be made with flanged or filleted edges on
both sides or on one side, so as to overlap, & thereby form ridges between the
furrows, of which Figure 6 is an example, or both ridges and furrows may have
filleted edges as shown in Figure 7, or with any substitute for same, and the
furrows and ridges may be made and fixed singly, or in pairs, or in flitches of
three or more furrows.
For the fixing in position for use of this roofing or awning, if used sloping and
intended to be permanent, the channels & ridges may be treated as rafters and
nailed or spiked to wall plates or breastsummers with the tops of the plates or
breastsummers notched or blocked to suit, or otherwise in any more convenient
manner. And if used for permanent flat roofing or with a slight fall, the channels
and ridges may be treated as joists and be built in, or may pass over the top of
the wall & be nailed to wall plates, or may be loaded over their bearings by
parapets being built over them, or be secured in any other convenient manner.
And when only required for a temporary awning over men or animals, or over
goods or materials it may be laid without nailing, to rest on bearers or trestles; or
on tops of hurdles, or on scaffolding, & be supported thereby, & may be maintained
in position while required, by ledges on top, or by bands, ties, straps, dogs, or other
temporary fastenings, or weights on top.
'
The foregoing description is illustrated by the accompanying Drawing, on which
Figure 1, shows the furrows composed each of two boards on edge, & a flat bottom
board between them, and inverted channel ridges, Figure 2 same but having a
wider bottom board passing under the upright ones. Figure 3 shows the furrows
hollowed out of solid timber. Figure 4 shows the channels or furrows having the
bottom board raised and housed into the sides. Figure 5 shows the channels fixed
with spaces between, and also having internal angle fillets. Figure 6 shows the
channels side by side with overlapping top edges as connected ridges. Figure 7
shows them with filleted top edges and interlocking ridges.
Having now particularly described and ascertained, the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1 The exclusive right of making & using channel roofing and awning (as before
described) formed with channeled timbers placed at small distances apart and used
instead of (or in addition to) common joists or rafters: The chanelled timbers
forming furrows in the roofing, & the spaces between the furrows being covered by
inverted channels as ridges, & the whole being a novel substitute for ordinary
weather boarded roofing.
:
2nd The exclusive right of roofing with such channeled timbers placed close
together, without spaces between, leaving only joints between them (& not spaces)
and of covering the joints with inverted channels as ridges.
3rd The right of using channeled timbers having overlapping edges, instead of
separate ridges, or having filleted edges.
4th The right of using the channeled timbers lined with zinc or other lining or
being not lined, and the right of using the ridges covered with zinc or other
covering, or not so covered.

page_text: 5th The right of using the channels with wider lining made to overlap the edges
of the adjoining channels as a substitute for separate ridges.
6th The right of using sheet iron or other material as a substitute for wood in
the ridges.
.
7th The right of using common channel bar iron or specially rolled iron as a
substitute for wood furrows.
8th The right of using the channels singly, or in pairs, or in flitches made up of
three or more furrows.
