PROVISIONAL SPECIFICATION.
Improved Arrangements for Heating Forced Draught and
Ventilating Steamships..
THOMAS MANSON RYMER-JONES Member of the Institution of Civil Engineers
28 Budge Row Cannon Street City private address 46 Richmond Gardens
Uxbridge Road do hereby declare the nature of this invention to be as
follows:-
This invention consists in utilising the waste heat from the funnels of steamers
by means of a jacket around the funnel, a fan for forcing the draft through the
furnaces and pipes leading from the different parts of the vessel into the said jacket
for ventilating purposes.
When the forced draft is required the fan draws a downward current through the
jacket, passing over the heated surface of the funnel, at the same time drawing the
foul & heated air by means of the pipes from all parts of the ship.
When in harbor and when the forced draft through the furnaces is not
required, the fan is stopped and the heat from the funnel causes an upward
draft through the jacket setting up a thorough system of ventilation from every
part of the ship communicated with through the ventilating pipes.
Dated this 16th day of January 1893.

I THOMAS MANSON RYMER-JONES Member of the Institution of Civil
Engineers Loudon of 46 Richmond Gardens Uxbridge Road London W. 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
statement, reference being made to the accompanying sheet of drawings:-
:-
This invention consists in utilising the waste heat from the funnel A. of steamers
by means of a jacket B around the funnel with a fan C for forcing the draft
through the furnaces, and pipes D leading from the different parts of the vessel
into the said jacket for ventilating purposes.
When the forced draft is required the fan C draws a downward current through
the jacket B passing over the heated surface of the funnel, at the same time
drawing the foul and heated air, by means of pipes D from all parts of the ship.
When in harbor and when the forced draft through the furnaces is not required,
the fan C can be stopped and the heat from the funnel with damped-down furnaces
is sufficient to cause an upward draught through the jacket setting up a thorough
system of ventilation from every part of the ship communicated with through the
ventilating pipes D. Suitable valves are provided wherever required to regulate
the draught.
The drawing shews the position of the jacket around the funnel with the current
of ventilation marked in upward arrows through the feeders & jacket-whilst the
heated forced draft is marked in downward arrows.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed 1 declare that what !
claim is
1st. An automatic system of ventilation by the use of the waste heat from the
funnels of vessels using steam.
2nd. The utilisation of waste heat from the funnels of vessels using steam for
the heating of a forced draft.
Dated this 14th day of October 1893.
