PROVISIONAL SPECIFICATION.
Improvements in Earthenware Ventilators.
We, FREDERIC SMITH, of 29 Bridgewater Chambers, Manchester, in the
County of Lancaster, Architect, JOHN JOHNSTON GREEN, and WILLIAM OATES,
of the Firm of Oates and Green Limited, Claremount, Halifax, in the County of
York, Sanitary Engineers, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new construction and manufacture of ventilators
specially adapted for use in connection with stables, mistals and other buildings.
We propose to manufacture the ventilator of glazed earthenware so that noxious
vapours cannot enter into nor permeate the material, consequently they will be free
from bad smells and being made of glazed earthenware they will not be required
to be painted. The bottom portion of the ventilator is made with openings or
funnels having one orifice on the outside for the atmosphere to enter, whilst the
opposite end of the said funnel communicates with the central chamber or updraught.
Upon the top of this central chamber we place a cap having openings or louvres to
assist in the updraught of the ventilator.
Dated this 29th day of November 1894.

Improvements in Earthenware Ventilators.
We, FREDERIC SMITH. of 29, Bridgewater Chambers, Manchester, in the
County of Lancaster, Architect, JOHN JOHNSTON GREEN, and WILLIAM OATES,
of the Firm of Oates and Green, Limited, Claremount, Halifax, in the County of
York, Sanitary Engineers, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :--
This invention relates to a new construction and manufacture of ventilators
specially adapted for use in connection with stables, mistals or shippons and other
buildings.
We propose to manufacture the ventilator of glazed earthenware so that noxious
vapours cannot enter into nor permeate the material, consequently they will be free
from bad smells and being made of glazed earthenware they will not be required to
be painted.
The bottom portion of the ventilator is made with openings or funnels having an
orifice on the outside for the atmosphere to enter, whilst the opposite end of the
said funnel communicates with the central chamber or up-draught.
Upon the top of this central chamber we place a cap having openings or louvres
to assist in the up-draught of the ventilator.
Reference to the accompanying sheet of drawings will make our invention more
easily understood wherein Fig. 1 is a vertical section of our improved earthenware
ventilator and Fig. 2 front elevation of same.

page_text: The ventilator is secured to the roof of the building by cement A and it is
provided with one or more openings or funnels B for atmospheric air to enter
which passes out through outlet C. These latter openings materially assist the
up-draught of the ventilator. By constructing ventilators of earthenware there is
no corrosion as is the case where metal is used or metal combined with wood, the
ammonia arising from stables being very destructive with metals.
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 :-
Firstly. The manufacture of ventilators for stables and the like composed of
earthenware.
Secondly. The construction of earthenware ventilators having one or more
funnels B in combination with louvres or outlets C as herein shewn and described.
