page_text: I, JAMES MCCONACHY, of 53 Ardgowan Street, Port Glasgow, in the County of
Renfrew, North Britain, Joiner, 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 stateinent, that is to say
-
My said Invention has for its object to improve the construction and action of
ventilating apparatus My improved apparatus which presents a sightly appearance
both externally and internally allows air to pass through whilst preventing the passage
of rain to a great extent, and it is applicable in various situations and in various
ways
In carrying out my Invention according to one modification I form what may be
termed a ventilating panel which may be fitted in place of a set of louvres The panel
comprises an outer and an inner shell, fixed upon a frame of a rectangular or other
convenient shape, the pinel being made of wood or other suitable material or com-
bination of materials Ench shell is grooved or otherwise shaped on its outer and inner
sides so as to presenta corrugated section, and grooves are cut or formed in the outer
side across or transversely to the corrugations so as to penetrate and form holes
through the corrugation ridges at distances apart which are by preference regular
The shells are placed so that the holes in one are opposite unperforated parts of the
other, and in some cases a sheet of perforated metal or wire gauze is fixed in between
the shells The space between the shells is by preference divided by bars or partitions
which forin channels running along the insides of the corrugations, and provision is
made for the egress or draining of any rain water which may enter the holes in the
outer shell If the ventilating panel is placed with the corrugations vertical or inclined
rain water can run down along the internal channels and pass out through openings
provided at their lower ends If the corrugations are horizontal rain water can run
out through the outer holes, the internal partitions being made flush with the bottonis
of the holes, and inclined, or the entire panel may be slightly inclined to give a
downward and outward inclination to the partition surfaces If desired sliding boards
or plates may be fitted on the outer or inner side of the ventilating panel for closing
it more or less

page_text: Where it is desired to apply the ventilating apparatus in the form of shaft or large
vertical tube, as for example, for ventilating holds of steamers, I fit a number of the
ventilating pinels round the upper part of the shaft, and I divide the shaft internally
by three or more equidist int radial partitions forming as many suparite vertical
chinnels With this arrangement in whatever direction the wind or air current mu
act on the apparatus, will be led into and pass down one or more of the vertical
channels always leaving one or more other channels for the ascent and escape of used
ar from the hold
On an accompanying sheet of explanatory drawings figure, 1, is
front elevation of
a ventilator panel as in ide according to my Invention and figures, 2, and 3, are
horizontal and vertical sections corresponding to figure, 1 The pincl is mide with
outer and inner corrugated shells, A, B, the corrugations being vertical and the
intern il spare being divided into vertical channels by partitions, C _ Angular
grooves, D, e cut across the corrugations to form openings, and a sheet, E, of wie
gauze or perforated metal is fixed in the middle of the pinel for the ur entering at
one side to pass through on its way to the other sido
Figure, 4, is a horizontal section of the upper part of a cylindrical ventilating shaft
having a number of my improved ventilating panels, P, fixed around it
The shaft is
divided by radial partitions, Q, arranged so that there are separate channels for
ascending and descending air currents in whatever direction the external air current
may be moving
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-A ventilitmg panel constructed substantially as horeinbefore described and as
shown in figures, 1, 2, and 3, of the accompanying drawings
2-A ventilating shaft provided with my improved ventilating panels at its upper
part and divided internally by radi il partitions, substantially as herein before described
and as shown in figure, 4, of the accompanying drawings
