I, JOHN BULLOUGH, of Accrington, in the County of Lancaster,
Machinist, do hereby declare the nature of the said Invention for
'IMPROVED MEANS AND APPARATUS FOR OBTAINING AND CIRCULATING HEAT, AND
IN THE APPLICATION THEREOP TO MACHINES FOR SIZING AND DRYING YARN," to be
as follows:
This Invention has for its object the utilizing in connection with
suitable apparatus the waste heat and hot gases arising from the
furnaces of steam boilers for the purpose of heating air or water for
drying yarn. Or of the application and use of such waste heat and hot
gases for drying yarn alone and without the use of hot air or water,
whereby I am enabled to dispense with the use of steam or heat here-
tofore required to be and specially provided for drying yarn in machines
of this class.
Firstly. I will describe a means and apparatus for utilizing the waste
heat or gases arising from furnaces of steam boilers, so as to heat and
circulate air through a sizing and drying machine. Near to the rear
end of the boiler, I construct a "heating chamber," which forms a

page_text: portion of the ordinary flue, and which chamber like the rest of the flue,
is charged with heat and gases arising from the furnace during their
passage therefrom to the chimney. Within this heating chamber I
place a pipe or series of pipes, one end of which extends to the outside
of the said heating chamber; the other end of the coil extends to and is
secured to the casing of an exhaust fan. It will thus be seen that the
fan will receive its supply of air through the coiled pipe within the
heating chamber, the fan discharging the air so heated along a pipe to a
branch pipe from thence it circulates through a series of pipes
(suitably arranged within the said machine) partially through the
propelling action of the fan, and partially through the draught of the
chimney with which the terminating pipe of the series is connected, or
I may throw the air so heated directly on the yarn.
Secondly. When employing heated water as a drying medium, I have
a like heating chamber and coiled pipe or pipes, a force pump being
employed to cause a circulating of the water so heated through the
pipes within the machine, the supply being obtained from a cistern, and
the terminating end of the piping discharges the water to this cistern,
there being no waste or loss other than that arising from evaporation.
Thirdly. When employing for a like purpose of drying yarn the heat
or hot gases arising from the furnaces of steam boilers, I introduce to
the flue at a point near the rear end of the boiler one end of a pipe, the
other end is connected to a fan which on being put in operation draws
in lieu of air the heated gases from the fluo which are discharged from
the said fan into and along a pipe connected with a series of pipes
arranged within the sizing and drying machine, the discharge pipe of
the series being connected with the chimney, as described in connection
with the apparatus employed for utilizing waste heat for heating air.
It will thus be seen that hot air, heated water, or the licated gases
arising from the furnaces of steam boilers may be employed for the
purpose of drying the yarn in sizing and drying machines, there being
in no case any fuel or steam specially provided or required for obtaining
the heat requisite for such drying purposes.
