PROVISIONAL SPECIFICATION.
A Ventilator for Hay, Corn, and other such Substances when
Stored in Stacks.
We, DOUGLAS TAYLOR, and WALTER TAYLOR, of Wilton Hill, Hawick, in the
County of Roxburgh, Engineers do hereby declare the nature of this invention to be
as follows:-
Our invention is for the purpose of providing ventilation for hay, corn, and
other such matters when stored in stacks.
Before the stack is begun we fix our ventilator by any convenient method, such as
attaching it to a conical or spiked basal portion, which may be easily fixed in the
ground. The framework of the ventilator consists of four longitudinal bars of iron
or other suitable material. Attached to these at suitable distances are sets of four
transverse bars of iron or other suitable material, and which extend beyond the
framework on each side. A tube of sheet iron or other suitable material is inserted
in the upper part of the framework, and is of such a size and shape as to move freely
up and down within the framework. To the edge of the upper orifice of the tube is
attached a conical appendage truncated at the top and extending about two feet from
the top of the tube downwards. Above this cover and over the top of the tube may
be fixed another conical cover, which proceeds to a point over but not in contact
with the tube. This upper cover is fixed so that the heated air, moisture, or vapour
'can get freely out, but rain is prevented getting in.
As the stack is being built the transverse bars cause the stems of corn or other
such matter that is being stored to hang upon these bars in a position sloping
upwards, thus assisting the upward course of air, gas, or vapour through the
ventilator. The tube is allowed to sink, within the framework until the lower conical
cover, which is attached to the tube rests on the stack. The cover prevents the rain
driving into the tube and so down the ventilator.

A Ventilator for Hay, Corn, and other such Substances when
Stored in Stacks..
We DOUGLAS TAYLOR and WALTER TAYLOR of Wilton Hill, Hawick in the
County of Roxburgh Engineers do hereby declare the nature of this invention and
in what mannor the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention is for the purpose of providing ventilation. for hay, corn, or other
such substances when stored in stacks.
The framework of the ventilator consists of four vertical bars of iron, wood, or
other suitable material. These are attached to a basal portion adapted for holding
the framework upright. To the vertical bars are secured at various distances sets of
transverse bars of wood, metal, or other suitable material, which extend beyond
the framework on all sides. The sets usually consist of four bars two being on
opposite sides of the vertical frame and parallel to one another, and two others secured
upon these at right angles to them. If desired cross pieces may be fastened to these
transverse bars at a little distance from the ends of the said bars.
A tube of any section and size that can easily slide up and down within the frame-
work is inserted in the upper part of the said framework. This tube may be composed
of wood or metal and is perforated laterally. At or near the edge of the upper orifice
of the tube is attached a conical appendage truncated at the top so as not to cover
the orifice of the tube and extending outwards and downwards from the sides of
the tube. Above this cover and over the top of the tube is fixed another conical
cover which proceeds to a point. This top cover is fixed to the bottom cover or to
the tube so that a space is left between the covers for a free passage from the tube
to the outer air. As the top cover is right over the orifice of the tube and partly
overlaps the bottom cover, rain is prevented from getting within the tube.
As the stack is being built the transverse bars cause the stems of corn or other
matter, that is being stacked, to hang upon these bars in a position sloping upwards,
thus assisting in the upward course of air, gas, or vapour, through the ventilator.
The tube is allowed to sink within the ventilator until the lower conical cover
attached to it rests on the top of the stack.
During the process of stacking the tube and covers can be raised, and prevented
from descending by inserting a rod through the lateral perforations of the tube. This
rod must be long enough to reach beyond the stack so that when the stack is finished
it may be conveniently withdrawn and the tube allowed to descend till the bottom
cover rests upon the top of the stack.
To show more clearly how our invention is carried out, we furnish drawings in
which similar letters represent corresponding parts throughout.

our said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1st. A ventilator for use in stacks substantially as described in the foregoing
specification.
2nd. The framework of a ventilator for use in stacks consisting of four vertical
supports with a basal portion and transverse bars substantially as described.
3rd. A tube with or without lateral perforations joined to a double cover to be
used in connection with the framework of a ventilator for stacks substantially as
described.
