Blackfriars in the County of Surrey Engineer for an invention of "IMPROVE-
MENTS IN HOSE COUPLINGS"
PROVISIONAL SPECIFICATION left by the said James Cadoux Hudson at
the Office of the Commissioners of Patents on the 1st March 1882.
JAMES CADOUX HUDSON of 75 Upper Ground Street Blackfriars in the County
of Surrey Engineer, "IMPROVEMENTS IN HOSE COUPLINGS
"
This invention has for its object the coupling together of bose pipes such as are
used in connection with fire engines but is equally applicable for joining together
pipes flexible or otherwise which require a connection readily made and separated.
This improved coupling consists mainly of two parts one male the other female
each part has a cylindrical portion grooved or otherwise on to which the hose is
fastened by binding with wire as usual with ordinary couplings or by other
suitable means. In the female part there is an internal circular recess which
contains one or more catch plates each catch plate having a plate spring attached.
The spring presses at bottom of recess and tends to force the catch plate out of the
recess. To the plate a stud is attached which passes out through bottom of recess
to outside of coupling and there carries a fixed or swivel nob which can be used in
unwinding the hose and also acts as a stop to the spring.
The male-part has a circular groove formed in its outer circumference to receive
the catch plate or plates.
When the coupling is desired to be made the male part is thrust into the female,
The end of the male part moves back the catch plate or plates into their recess and
bending the plate spring until the catch plate is in a position to fall into the
circular recess formed in male part. The catch-plate or plates are then forced
forward by springs and the coupling is made. The catch plates and groove in
male part are of such a form as to prevent the part being pulled asunder by any
strain on hose.

page_text: In order to separate the coupling the catch plate or plates are withdrawn by
means of a nob on stud and the parts are detached:
An india rubber ring is placed in a seat formed for it in female part and the
end of male part pressing against it when the coupling is made and forms a water
tight joint.
Other contrivances may be used for withdrawing the catch plate from recess in
male coupling when disconnecting the joint.
A pin may be used laying parallel with the axis of coupling and passing through
catch plate or spring and through slots in sides of recess to outside of coupling.
The pin forms a stop to spring and also allows the catch plate to be withdrawn.
In another arrangement the stop may be formed at ends of plate spring. The
catch plate has a handle or finger piece by which it may be withdrawn access
being given to handle or finger piece by means of a part of the back of recess
being cut away.

JAMES CADOUX HUDSON of 75 Upper Ground Street Blackfriars in the County
of Surrey Engineer "IMPROVEMENTS IN HOSE COUPLINGS "
This invention has for its object the coupling together of hose pipes such as are
used in connection with fire engines but it is equally applicable for joining
together pipes flexible or otherwise, which require a connection readily made or
separated.
The improved coupling consists mainly of two parts one male and the other
female each has a cylindrical portion grooved or otherwise on to which the hose is
fastened by binding with wiro as is usual with ordinary hose couplings or other
means which may be found desirable.
In the female part there is an internal circular recess which contains ono or
more catchplates each catch plate having a plate spring attached. The spring
presses at bottom of recess and tends to force the catch-plate out of recess. To
the catch plate a stud is attached which passes out thro' bottom of recess to
outside of coupling and there carries a fixed or swivel knob which can be used in
unwinding the hose and which also acts as a stop to spring. The male part has a
circular recess in its outer circumference formed to receive the catch plate or
plates. When the coupling is desired to be made the male part is thrust into the
female, the end of male part moves back the catch plato or plates by bending the
plate springs until the catch plate is in a position to fall into the circular recess
formed in male coupling, the catch plate or plates are then forced forward by the
plate springs and the coupling is made.
In order to uncouple the joint the catch plate is drawn back by means of swivel
knob and the parts are detached. An india rubber ring is placed in a recess
in female part and the end of male part presses against it when the coupling is
made and forms a water tight joint.
Other arrangements may be used for withdrawing the catch-plates from recess
in male coupling when disconnecting the joint. A pin laying parallel with the
axis of coupling and passing through catch plate or spring and passing through
slots in sides of recess to outside of coupling may be used the pin forms a stop to
spring and also allows the catch plate to be withdrawn.
In another arrangement the stop may be formed at end of plate springs, the
catch plate having a handle or finger piece on it which may be withdrawn access
being had to it by means of a part of back of recess being cut away.
Having now described the nature and objects of my said invention I will now
proceed to illustrate more fully by aid of accompanying sheet of Drawings in
which Figure 1 is a longitudinal section of an arrangement of coupling made
according to one portion of this invention. Figure 2 is a cross section of same.
Figure 3 is a longitudinal section of another arrangement and Figure 4 is a cross
section of same
Figure 5 is a longitudinal section Figure 6 a cross section. Figure 7 a side
elevation and Figure 8 an end elevation of another arrangement.
Figure 9 is a longitudinal section. Figure 10 a cross section and Figure 11 a
side elevation of another arrangement. Similar parts in these Figures have
corresponding letters of reference.
In Figures 1 and 2 A is the male part B is the female. On to the portions CC
the hose pipes are attached. In the female part, the internal circular recess D

page_text: contains one or more catch plates E E formed with square edges E¹ E' as shewn in
full lines or bevilled as shewn by dotted lines E2 E2 each having a plate spring FF
attached the plate spring F F presses at the bottom of recess and tends to force the
catch plate E E out of recess. To the plate E E a stud G is attached having a
fixed or swivel knob H. In the male part A a circular recess I is formed. The
end of A being bevelled as shewn at K. An india rubber ring L forms a water
tight joint. In order to make the coupling, the male part A is thrust into the
female part B and the bevilled end of male part K moves back the catch plate or
plates EE by bending the plate springs F F until the catch plate or plates E E
are in a position to fall into recess I when they are forced forward by plate springs
FF and the coupling is made. In order to uncouple the joint the catch plates are
withdrawn by means of the knob H and the parts are detached.
Figures 3 and 4 illustrate a somewhat similar arrangement to that of Figures 1
and 2 similar parts having corresponding letters the main difference being that the
catch plates are bevilled as shown and the end K of male part not bevilled but
formed square or slightly rounded. In this case the catch plates are forced back
by the end of male part forcing against the inclined surface of catch plates.
In Figures 5, 6, 7 and 8 the catch plate E has a projection M through which a
pin N passes to outside of coupling and forms both a stop to springs F F and a
means of withdrawing the catch plates when it is desired to uncouple the joint.
The end K of male part A and the catch plates L L may be formed as in Figures 1
and 2 or as in Figures 3 and 4 the former being the arrangement shewn in
Figures 5, 6, 7 and 8.
In Figures 9, 10 and 11 the catch-plates E E are withdrawn by means of 'a
bandle or finger piece O a part of side of recess D being cut away to give access
to it. A stop P P is formed to plate springs F F although it can also be formed
as shewn at R on finger pieces O. The end K of male part A. and the catch plate
EE can be formed as in figures 1 and 2 or Figures 3 and 4.
Having now described my improvements in hose couplings and the manner of
performing or carrying the same into practice I would remark that I make no
claim to any of the parts separately which are well known and in common use
But what I claim as my improvements in hose couplings is the arrangement of
catch plate with plate spring in a recess of female part of coupling engaging into
a recess formed in male part of coupling the catch plate being bevilled or plain
and the male part of coupling which forces back the catch plate being bevilled or
plain as illustrated and described also the arrangements for pulling back the catch
plates as illustrated and described substantially in the manner and for the purpose
hereinbefore more particularly set forth and represented in the drawings hereto
annexed.
In witness whereof I the said James Cadoux Hudson have hereunto set my
hand and seal this Eighteenth day of August in the year of our Lord one
hundred and night treen
