parts-male & female. The male part is made with two projection-one on each
side. The female is made with two grooves one on each side with two recesses
one fore projection to pass into, and one for India Rubber Washer, also with two
projection on the outside for universal handles. There are two lock pins fitted &
secured by spiral springs & stud screws from the outside end-These pins project
on each side of one groove into recess-the male part when inserted into female
part. The projection are placed into the grooves--forced home upon the washer-
and it is locked either right or left by a slight turn over the pins into recess―This
is then a perfect tight joint. The handles upon this coupling is fitted with straps
for securing hosepiping when coiled up in coils also to inable hosepiping to be.
uncoiled without unfastening straps.

ALFRED DEVONSHIRE 5 East Lane Paisley North Britain, in the County of West
Renfrewshire Firemaster to J. & B. Coats Paisley I do hereby declare the nature
of my invention for THE CONNECTING OF FIRE HOSEPIPING TOGETHER, AND TO
MAKE A TIGHT JOINT UNDER PRESSURE. 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 make a connection upon hosepiping
hydrants &c. This improved instantaneous hose coupling is formed by two parts,
male and female, The male part is made with two projection, one on each side.
The female part is made with two grooves, one on each side, with two recesses,
one projection to pass into, and one for India Rubber washer, also with two projec-
tion on the outside for universal handles to work upon. There are two lock_pins
fitted and secured by spiral springs and stud screws from the outside end. These
pins project on each side of one groove into recess. The male part when inserted
into female part, The projection are placed into the grooves and forced home upon
the washer and is locked either right or left by a slight turn over the pins into
recess. There is then a perfect tight joint. The handles upon the coupling is
fitted with straps for securing hosepiping when coiled up in coils, also to inable hose-
piping to be uncoiled without unfastening the straps. This hose coupling can also
be made without handles or revolving caps, or any projection on the outside. This
is a great advantage over any other hose coupling for stowing hose in engines, or
coiling hose upon reels. The simplicity of the coupling is so simple that the same
form in connecting the two parts together, is applied to disconnecting the joint.
And in order that my said invention, and the manner of performing the same
may be properly understood, I hereunto append a sheet of explanatory Drawing to
be hereinafter referred to, and representing two examples of my improved hose
coupling for making a tight joint when 'under pressure. In these Drawings the
saine reference letters are used to mark the same, or like parts wherever they are
repeated. Letter A, on the accompanying sheet of Drawing is showing the female
part of coupling with the revolving caps & handles for straps G, The handles are
fitted on caps and kept in their places with screw pins J, working in a groove on
the projection L, Letter B is the male part showing how the square projection are
placed E, and how they are protected by a projecting collar M, Letter C, is the
end view showing how the projection E, enters for connecting the two parts together
also showing the top part of stud screws K, one on each side of groove H. These
studs screws keeps the spiral springs down in their places N. and projection studs
in recess O. Letter D, is showing a half section without projection & handles or caps
on the outside G but showing the two parts connected together upon the India
Rubber washer F, If desired four projection pins & springs can be applied in the
same manner as the two are for keeping the male part more secured from being
disconnected,

page_text: Having thus particularly discribed my said invention and modification and the
manner of preforming the same, I have to state I do not restrict myself to the
precise details berein discribed or delineated, but that what I believe to be novel
original, and claim as my Invention is
First, in the coupling can be used with; or without any projection on the outside
for handles or revolving caps of any sort, or lugs for keys.
Second, That the spiral springs for securing the projection pins for locking the
male part when connected, being so arranged in the female part but cannot get
damaged in anyway.
Third, That, that the same action for connecting the coupling either right or left
over the lock pins N. answers the same for disconnecting the joint A & B.
