No. 24076.—28th February, 1908.—JAMES HARGREAVES,
of Eden Terrace, New North Road, Auckland, New Zealand,
Ventilating Engineer. An improvement in the construction
of ventilators.*

Claim.—An improvement in the construction of ventilators,
particularly relating to ventilators used for the admission
of air into public buildings and the like. In ventilators of
the quadrant type, in combination, the front plate of the
valve hinged to the framework independently of the sides
or shrouds, so that it can be opened outwards to facilitate
cleaning and inspection; the baffle-plate fitted into a groove
so that it can be raised for the same purpose; the front
plate normally fastened to the shrouds by turnbuttons, and
when open is held by a chain attached to a stay connecting
the sides; and a stout cloth pad, or any other material, inserted
in the shrouds, and working against the sides or neck, allowing
opening and closing to any distance required, and rendering
it both noiseless and airtight. This invention is stated to be
applicable to other forms of ventilators.

and steam up, the main body of the products of combustion,
&c., is diverted from the smoke-stack or funnel and returned,
by the aid of controllable steam-jets, to the fire-box.
