An Improved Ventilator for Buildings.
I WILLIAM CLEMENT WILLIAMS Architect of the firm of Messieurs Horsfall and
Williams of George Street Halifax in the county of York Architects and Surveyors,
do hereby declare the nature of this Invention to be as follows:
The object of my invention is to provide an efficient air inlet or outlet for
ventilating buildings, which can be built into the walis and present an ornamental
appearance, at the same time being an efficient ventilator.
I construct my ventilator preferably of earthenware or it may be of cast iron or
other suitable substance; the outer face consists of an ornamental plate with openings
at each end of a slot like shape or other suitable form, and in the centre an ornamental
solid portion, this central portion has two arms which act as deflectors, the inner part
is of a box like form at each end, with a passage out towards the centre.
On the air blowing sideways or straight against the ventilator, it is deflected by the
wings, and passes around each of the chambers, before it can pass through the central
passage, into the buildings, or any number of chambers may be used.
