EXTINGUISH- ING OF FIRES IN MILLS & FACTORIES WHEN NO ONE IS PRESENT AND BEING SELF ACTING
Year: 1885

page_text: ALFRED DEVONSHIRE 5 East Lane Paisley N.B. Firemaster to Messrs J. & P.
Coats Paisley I do hereby declare the nature of my invention for THE EXTINGUISH-
ING OF FIRES IN MILLS & FACTORIES WHEN NO ONE IS PRESENT AND BEING SELF
ACTING, to be as follows:-
This Invention relates principally to the Extinguishing of Fires in Mills
Factories Wood Yards Ship Building Yards Engineers Shops &c. This improved
Automatic Extinguisher is formed by two valves and a perforated rose being
connected to an upright pipe with a stop cock in centre of pipe to turn off the
water when tying on cotton thread or fixing fusible metal band. This stop cock
also admits of any one running in and turning off the water when the Fire is
extinguished underneath where it hangs thus throwing the pressure on any other
Extinguisher that may be at work. The two valves have lugs attached to each &
these are fastened tight by chemically prepared cotton thread or fusible metal band
or band metal cotton which ignites when touched by flame liberating the
valves for action by pressure of water in pipe. These Extinguishers hangs suspended
from ceiling attached to an inch & half iron pipe.

North Britain, Firemaster to Messrs J & P Coats Paisley, I do hereby declare the
nature of my invention for THE EXTINGUISHING OF FIRES IN MILLS FACTORIES
AND SHIPS WHEN NO ONE IS PRESENT 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 principally to extinguishing of fires in Mills Factories
Warehouses Ships Engineers Shops &c.
This improved Automatic Extinguisher is formed by one valve, instead of two
formerly proposed, and verdically placed in a perforated rose which is connected to
pipes carried near to the ceilings without a stop cock in the centre as formerly
proposed. The perforated rose is constructed in two parts, The valve being fitted.
in to the upper part which makes a tight metal joint, The lower part of rose is
placed over the end of valve rod, and the two parts of the rose is connected
together in the centre by a screw. The inside of rose is turned out, and the
perforated holes are countersunk from the inside, This is to prevent dust or
sediment gathering in the inside of rose, thereby prevents the perforation from
becoming choked when brought into action. There are two projecting lugs, one
on each side of the outside of lower part of rose, These projecting lugs are for
fastening on chemically prepared cotton thread to or fixing on copper band, or any
other metal bands which are joined together by fusible solder-when used for
pressing the valve home to its seat. There is also a small projecting piece at the
bottom part of rose-where a brass cap is fitted over when used also for pressing
the valve home to its seat-is soldered by fusible solder. This brass cap is made
with two arms on the bottom part-and in the centre a hole is screwed for
screwing over the end of valve rod. The valve and rod is in one piece of brass
metal made with a knob at one end-and is turned to fit in the inside of upper part
of rose.
The rod end is screwed about 1½ of an inch long-which is screwed
through the bottom part of brass cap, a inch nut is fitted on-and pinned to the
end of rod for screwing the valve home to its seat when the brass cap is her-
metically soldered with fusible solder, or when the copper bands-or any other
metal bands are being used. The copper bands-or any other metal bands are soldered
together in one or two places with fusible solder-which melts at a very low
temperature of heat, or on a slight tuch of flame. The chemically prepared cotton
bands answers the same purpose as the metal bands. And in order that my said
invention, and the manner of preforming the same may be properly understood, I here-
unto append a sheet of explanatory Drawing to be hereinafter referred to, and
representing two examples of my improved Automatics Fire Extinguishers. In
these Drawings the same reference letters are used to mark the same, or like parts
wherever they are repeated. Letter A, on the accompanying sheet of Drawing is
a vertical section showing how the valve is pressed home to its seat by a copper
band soldered in one or two places with fusible solder. The band is hooked over
the two projecting lugs E, and passing underneath the arms F, at the bottom part

page_text: of brass cap, The band G, is tightened by placeing a key over the nut H, at the end
of valve rod, which is screwed home to its seat through the brass cap I, Letter B,
is a vertical section showing how the valve is kept pressed home to its seat by the
brass cap I, being hermetically soldered to the projecting part on lower part of the
rose J, The valve rod K, is first placed through the bottom part of rose, and then
screwed through the brass cap I, which is placed over projecting piece J, and
soldered together with fusible solder. The nut H, is then pinned on, and the valve
screwed home as showned in section B, Letter C, is a vertical section showing the
valve K, liberated and at the bottom part of rose, as when in action. Létter D, is
a vertical half section showing how the valve K, is placed in the upper part of
rose L, and how the rose is connected together in the centre by a screw. The
lower part J, is connected to upper part L, which makes the rose complete. The
object of the rose being constructed in two parts is to allow the rose to be turned
out, and the perforation countersunk to prevent choking.
Having thus particularly discribed my said invention and modification and the
manner of preforming the same, I have to state that I do not restrict myself to the
precise details herein discribed delineate, but that what I believe to be novel
original and clame as my Invention is,
First, in the rose being constructed in two parts J & L.
Second, The copper bands or bands of any other metal being joined together by
fusible solder.
Third, A chemically prepared cotton.band
Fourth, A brass cap hermetically soldered on to bottom part of rose J.
Fifth, The arrangement of the valve rod K. Can be unscrewed for testing the
Automatics or washing out the pipes without disableing them in any way.
