PROVISIONAL SPECIFICATION..
Improvements in Apparatus for Automatically Operating Ventilators.
ARTHUR BAKER 22 Suffolk Street Leamington Coach Maker do hereby declare
the nature of this invention to be as follows:-
For opening ventilators of greenhouses stables and the like.
Metal guide "to fix on top frame" with hinged joint slotted holes in same to use
as ordinary guide when not desireable to use the self acting arrangement.
Metal bar with flap to fix on bottom frame.
Sliding fulcrum on bar to connect guide.
Steel spiral spring on bar to supply force.
Metal arm one end to secure spring the other end to receive band.
Metal lever on bar to compress spring.
Flexible. band, joined together with composition, holding lever and arm together.
Composition of wax, resins, pitch tar, and the like, that will melt at various,
fixed, temperatures.
When the heat inside rises to the temperature required, it will melt composition,
release lever that compresses spring, force up the guide, and the window or
ventilator opens.
The flexible band, and the compositions being the chief features, the other parts
lthough original are only mechanical parts which may be made in other forms, to
uit fittings which will be given in detail in my Complete Specification.
Dated this 8th day of June 1895.

Improvements in Apparatus for Automatically Operating Ventilators.
ARTHUR BAKER 22 Suffolk Street Leamington Coach Maker 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 :-
For opening ventilators of greenhouses stables and the like.
་
A Metal guide to fix on top frame with hinged joint. Slotted holes in same, to use
as ordinary guide when not desirable to use the self acting arrangement.
B Metal bar with flap to fix on bottom frame.
C Sliding fulcrum on bar to connect guide.
D Steel spiral spring on bar to supply force.
E Metal arm, one end to secure spring the other end to receive band.
F Metal lever on bar to compress spring.
G Flexible band joined together with composition, holding lever and arm
together.
H Composition of wax resins pitch and the like, that will melt at various fixed
temperatures as for instance, sixty, seventy or eighty degrees, Fahrenheit, and so on.
When the heat inside rises to the temperature required, it will melt composition,
the band will disunite, release lever that compresses spring, force up the guide and
the window or ventilator opens.

page_text: The flexible band and the compositions being the chief features, the other parts
although original, are only mechanical parts which may be made in other forms.
It is a most useful novelty, much needed, and can be made cheaply, each band
will be stamped with the degree of heat "Fahrenheit" that the composition is
intended to melt at.
Figure Two in the drawings is a modification of the same principle, to be used
when the window is out of reach, the apparatus to be fixed in a convenient place,
and connect with the ordinary guide on window by the cord (I) shewn running
round pulley (J).
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that
what I claim is
(1) Composition of wax resins pitch, tar and the like, in various proportions to
melt at various fixed temperatures Fahrenheit.
(2) The flexible band of glazed linen or other suitable material to be joined
together with the composition before described.
(3) Lever restraining a force in a certain position until the heat rises to the given
-temperature that melts composition.
Dated this Fifteenth day of June 1895.
