PROVISIONAL SPECIFICATION.
Improvements in Means or Apparatus for Ventilating or Removing
Deleterious Gases from Ships' Holds, Stores, or other Confined
Places.
I, WILLIAM BENJAMIN WALTERS of 47 Lime Street in the City of London,
Mechanical Engineer do hereby declare the nature of this invention (which has
been communicated to me from abroad by John Anderson and Archibald Morrison
trading as Anderson & Morrison of Dunedin in the Colony of New Zealand,
Plumbers) to be as follows:-
This invention has for its object to provide means or apparatus whereby ships'
holds, stores or other confined places can be ventilated or cleared of deleterious
gases with facility. According to this invention there are provided pipes or
passages which form communications between the place or places to be ventilated
or cleared of gases and some convenient place of discharge and in conjunction with
these pipes or passages ejectors or injectors are employed by which the gases are
withdrawn and discharged. The pipes or passages may be led from any convenient
part of the place to be ventilated or from which gases are to be removed. For
example when the invention is applied to a ship's hold pipes may be led from the
lower part or floor thereof and up to injectors or ejectors from which discharge
pipes lead into or alongside the funnel or the pipes may communicate with the
upper part of the hold or other place and pipes or passages may lead from the
outer air to the lower part of the hold or other place so that air is drawn there-
through as the air and gases are removed by the pipes at the upper part of the
hold or other place. The pipes or passages may be provided with perforations
through the portions of their length situated in the hold or other place. The pipes
by which outer air is admitted may in the case of ships be in communication with
the ordinary downcast veutilators.

COMPLETE SPECIFICATION.
Improvements in Means or Apparatus for Ventilating or Removing
Deleterious Gases from Ships' Holds, Stores, or other Confined
Places.
I WILLIAM BENJAMIN WALTERS of 47 Lime Street in the City of London
Mechanical Engineer do hereby declare the nature of this invention (which has
been communicated to me from abroad by John Anderson and Archibald Morrison
trading as Anderson & Morrison of Dunedin in the Colony of New Zealand
Plumbers) and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
This invention has for its object to provide means or apparatus whereby ships'
holds stores or other confined places can be ventilated or cleared of deleterious
gases with facility.
According to this invention there are provided pipes or passages which form
communications between the place or places to be ventilated or cleared of gases
and some convenient place of discharge and in conjunction with these pipes or
passages ejectors or injectors are employed by which the gases are withdrawn and
discharged.

page_text: The pipes or passages may be led from any convenient part of the place to be
ventilated or from which gases are to be removed. For example when the invention
is applied to a ship's-hold pipes may be led as shewn at a in Figure 1 of the
accompanying drawings from the lower part or floor thereof (and also from between
decks as shewn if desired) and up to injectors or ejectors from which a discharge
pipe or discharge pipes a lead into or alongside the funnel. As the deleterious
gases are removed purer air will take its place. This may gain access through any
ordinary inlets or by pipes as at c in connection with the ventilators as shewn.
Fig. 1 shews the arrangement of the ejectors drawn to a larger scale. Or the
pipes a may communicate with the upper part of the hold or other places as shewn
in Figure 2 and pipes or passages e may lead from the outer air to the lower part
of the hold or other place so that air is drawn therethrough as the air and gases
are removed by the pipes a at the upper part of the hold or other places. The
pipes or passages may be provided with perforations through the portions of their
length situated in the hold or other places.
The pipes c by which outer air is admitted may in the case of ships be in
communication with the ordinary downcast ventilators as shewn.
The ejectors may be of any suitable construction. A suitable form is shewn in
section in Figure 3. They may be operated by steam admitted to them from the
engine boilers.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. For ventilating or removing deleterious gases from ships'-holds stores or other
confined places the combination of perforated withdrawal pipes and an ejector or
ejectors substantially as hereinbefore described.
2. For ventilating or removing deleterious gases from ships'-holds stores or other
confined places the combination of perforated air inlet pipes and perforated with-
drawal pipes provided with an ejector or ejectors substantially as hereinbefore
described.
