PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Air for use in connection
with Stenter Finishing Machines.
I, ROBERT CAMPBELL ROSS, of Kildrum, Kells, Ballymena, County Antrim,
Dyer and Finisher, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to apparatus for heating air for use in connection with
stenter finishing machines.
In carrying out my invention I construct a furnace of brick or other suitable
material. Fitted, preferably, horizontally in the furnace are one or more tiers of
malleable or cast iron, or other pipes. The fire is located at one end of the furnace
and underneath the pipes, and, so that the products of combustion are emitted from
the opposite end of the furnace.
The pipes are supported in plates, at either end, fitted in the masonry of the
furnace.
The pipes, preferably at the cold air inlet end, are made fast, but, at the opposite
or delivery end they are fitted loosely so as to allow room for expansion and
contraction in length.
Fitted at the inlet end of the pipes is a box into which cold air is forced by a fan,
blower, or other air propeller. The hot air at the delivery end is collected in a
large pipe and is conveyed to the place where it is to be utilized.
With this invention air is obtained at a high temperature which imparts a
superior finish to certain goods. The cost of fixtures as compared with other
apparatuses is light and there is an economy in the working.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Heating Air for use in connection
with Stenter Finishing Machines.
ROBERT CAMPBELL Ross, of Kildrum Kells, Ballymena, County Antrim,
Dyer and Finisher, 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 :-
This invention relates to apparatus for heating air for use in connection with
stenter finishing machines.
In carrying out my invention I construct a furnace of brick or other suitable
material. Fitted, preferably, horizontally in the furnace are one or more tiers of
malleable or cast iron, or other pipes. The fire is located at one end of the furnace
and underneath the pipes, and, so that the products of combustion are emitted from
the opposite end of the furnace.
The pipes are supported in plates at either end, fitted in the masonry of the
furnace.
The pipes, preferably at the cold air inlet end, are made fast, but, at the opposite
or delivery end, they are fitted loosely so as to allow room for expansion and
contraction in length:
Fitted at the inlet end of the pipes is a box into which cold air is forced by a

page_text: fan, blower, or other air propeller. The hot air at the delivery end is collected in
a large pipe and is conveyed to the place where it is to be utilized.
With this invention air is obtained at a high temperature which imparts a
superior finish to certain goods. The cost of fixtures as compared with other
apparatuses is light and there is an economy in the working.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon
Fig. 1 is a longitudinal section of the furnace.
Fig. 2 is a section on the line x-x Fig. 1.
Fig. 3 is a section on the line y-y Fig. 1.
Fig. 4 is an end view.
Referring to the drawings a
The air heating apparatus consists of a brick furnace a which is, preferably, of
oblong shape. Fitted, preferably, horizontally in the furnace are four or other
number of tiers of pipes b. These pipes are supported at one end in a vertical
plate c and are held rigidly in place by jam nuts d, d¹. At the opposite or outlet
end the pipes b are supported loosely in a plate e so as to permit of expansion and
contraction. The plates c, e are carried in sleeves f, g, respectively, being bolted to.
the internal flanges f', g' of the sleeves. The inlet and delivery boxes h, i are
bolted to the external Hanges f, g, of the sleeves. The sleeves are firmly and
rigidly secured in the masonry of the furnace.
j is a fan, blower, or air propeller for forcing air through the pipes b, as indicated
by the arrows. k is the fire. the fire door. k³ fire bars. is a fire bridge.
n is the outlet for
m are bars fitted across the furnace for supporting the pipes b.
products of combustion. m¹ is the delivery pipe which conducts the hot air to the
place where it is to be used. The arrows at o represent the course of the flames
over the bridge l.
With this invention, as the temperature in the furnace is great, and as the pipes b
present a large heating surface, a high temperature is easily and quickly imparted
to the air which is forced continuously through the pipes by the fan j.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
An apparatus for heating air for use in connection with stenter finishing machines
constructed and operating substantially as herein before described with reference to
the drawings annexed.
