Improvements in the Method of and Apparatus for Drying and
Cooling Barrels, and Supplying Hot Air to Drying Rooms and
the like purposes.
I, WILLIAM FARRAR, of the Firm of Messrs. Farrar, Whitley, and Company,
of Victoria Foundry, Bramley, near Leeds, Engineers and Ironfounders, do hereby
declare the nature of this invention to be as follows:-
My invention has reference to improvements in the method of and apparatus for
drying and cooling barrels, and supplying hot air to drying rooms, and the like
purposes.
According to my said improvements the barrels are dried by the action of hot air
and afterwards cooled by the admission of cold air; my apparatus being so
constructed that it will admit either hot or cold air as required. Also instead of
the hot air being used for barrel drying purposes it may be used for heating drying
rooms, and also where steam is or can be used for drying the barrels it will supply
the cold air for cooling off purposes.
In carrying out my invention the cold air is obtained by a blower or fan and
passed into a tube or pipe (fitted with a suitable open and shut valve) the cold air
when required to be converted into hot air is passed (the said valve being then
open) into a heater composed of a furnace and pipes with air spaces between them
enclosed in a shell lined with firebrick or other refractory material, from the said
heater a pipe or tube branches into another pipe into which other pipes branch
which are fitted with a series of nozzles upon which are placed by means of the
bungholes the barrels to be dried and cooled, the said nozzles being adapted to fit
the bungholes of the barrels, the said pipes have also suitable gantrys for holding
the barrels in position. In connection with each nozzle is a valve which may be
opened or closed by hand or automatically by the actions of putting on the barrels
or taking them off the nozzles.
A pipe branches from the pipe leading from the blower or fan to the heater into
the pipe feeding the pipes fitted with the nozzles, so that when cold air is required
for cooling off the barrels after drying, the cold air is passed into the said branch
pipe and thence on to the nozzles, the said branch pipe valve being open and the
one leading to the heater shut.

In places where boilers are already in use or contemplated the cold air
heated by the waste gases derived from such boilers by passing the said gases into
a heater composed of tubes having air spaces between them, the hot air thereby
produced being utilized in manner aforesaid.

In carrying out my invention the cold air is obtained by a blower or fan A (such
as a "Roots" blower) and passed into a tube or pipe B, fitted with a suitable open
and shut valve C. The cold air when required to be converted into hot air is
passed (the said valve being then open) into a heater D, composed of a furnace D',
and pipes E, with air spaces F, between them enclosed in a shell G, lined with
firebrick H, or other refractory material, from the said heater a pipe or tube J
branches into another pipe L into which other pipes M branch, which are fitted
with a series of nozzles N upon which are placed, by means of the bungholes, the
barrels to be dried and cooled, the said nozzles being adapted to fit the bungholes of
the barrels. The said pipes have also suitable gantrys O for holding the barrels in
position. In connection with each nozzle is a valve which may be opened or
closed by hand, or automatically by the actions of putting on the barrels or taking
them off the nozzles.
A pipe P branches from the pipe B, leading from the blower or fan A to the
heater D into the pipe L feeding the pipes M fitted with the nozzles, so that when
cold air is required for cooling off the barrels after drying with hot air, the cold
air is passed into the said branch pipe and thence on to the nozzles, the said
branch pipe valve R being open, and the one, C, leading to the heater, shut.
The hot air may also be produced by passing steam around the tubes F enclosed
in the shell G, the steam to be obtained from a boiler or other source and passed to
the heater D.

page_text: In places where boilers are already in use or contemplated, the cold air may be
heated by the waste gases derived from such boilers, by passing the said gases into
a heater composed of chambers S, and tubes T, having air spaces U between them,
the hot air thereby produced being utilized in manner aforesaid, see Fig. 10. In
cases where the air is required to be filtered provision is made for this by an air
shaft V, communicating with an air trunk or flue W, through which the air is
drawn by a blower or fan X underneath, the cold air passing through layers of
cotton wool, or other such filtering medium, see Figs. 11, and 12.
The slides Y of the nozzle valves, see Figs. 7, and 8, are operated by hand
levers Z, pivoted at Z', the top of the said hand lever being connected to a link Z'
fastened to the slide Y which works in the plate Z³ upon the pipe M, its movement
being regulated by the slot Z and pin Z³.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A method of drying barrels by the action of hot air and afterwards cooling
them by the admission of cold air, substantially as set forth.
2. An apparatus for drying barrels by the action of hot air and afterwards cooling
them by the admission of cold air, comprising a blower or fan, pipes for conveying
the cold air to a heater or apparatus, where it becomes converted into hot air,
which is passed by pipes to nozzles upon which the barrels are placed, and valves
for opening or closing the passage for the said cold or hot airs, substantially as
shown and described.
3. In an apparatus for drying or cooling barrels, the combination of a blower or
fan A, pipes B, P, L, and M, heater D, valves C, nozzles N, and gantrys O, as
and for the purposes shown and described.
4. In a method of washing or drying barrels by the action of steam, the
admission of cold air for cooling the barrels, as set forth.
5. In an apparatus for cooling barrels by the admission of cold air, the
combination of blower or fan A, pipes B, P, L and M, nozzles N, and gantrys O,
such as shown and described.
6. An apparatus for drying barrels by the action of hot air, and cooling them by
the admission of cold air in which the cold air can either be passed directly to the
barrels for cooling purposes after the barrels have been washed or dried by the
action of steam, or can be passed to a heater for conversion into hot air for such
drying purposes, and then permit of the admission of cold air for cooling purposes,
substantially as set forth.
7. An apparatus for supplying hot air to drying rooms, for heating rooms, and
the like purposes, comprising a blower or fan, pipes for conveying the cold air from
a blower or fan to a heater having a series of tubes with air spaces between them
enclosed in a shell lined with firebrick, or other refractory material, substantially
as and for the purposes set forth.
