PROVISIONAL SPECIFICATION.
Improvements in Coupling Hoses and other Pipes.
JAMES CADOUX HUDSON 75 Upper Ground Street Blackfriars Road London
Engineer do hereby declare the nature of this invention to be as follows:-
This invention has for its object the coupling together of hose 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 and one female.
Each part has a cylindrical portion grooved or otherwise and formed as may be
required for fixing on to it the hose or other tubing. The cylindrical portion
attached to the female can be made to swivel as an ordinary screw coupling.
The male and female ends of coupling are formed as a bayonet joint and of
similar shape to Figs. 13. 14. 15. 16 in the Specification of Patent No. 3133
dated the 23rd June 1883, except that I can dispense with the slots or grooves
across the projections on the male end. The rubber ring forming the joint is
similarly arranged but instead of placing the spring stop in a position acting
radially from the centre of bore of coupling, I place it on the outer side of female
coupling and acting on a line parallel with the axis of bore of coupling, and
instead of the stop engaging in the slots in the projections on male end, the
spring stop is compressed when inserting the male into the female by the collar
on male end, and when the male end is turned within the female the spring stop
is forced into a hole, or slot, or recess in the collar when the ends have been
twisted into that position in which the bayonet joint will be completed. There
may be two, three or more projections on the male end and the outer flange of
female, behind which the projections on male are locked, will be cut away in
two, three or more places to admit the projections on male, and slots, holes, or
recesses will be formed in the collar on male of same number as the male
projections. The coupling can be made by a part turn to the right or left.
'When disconnecting the coupling the spring stop is pressed in with the thumb,
or by a small key until its end clears the flange on male end and the male and
female are disconnected by a slight turn to right or left..
The spring stop can be placed on the flange of male end and the stop engage with
slots, holes or recesses in the outer face of flange of female.
Also this spring stop can be used in connection with a coupling united by male
and female screw as in Figs. 5. 6. 7. 8 of the Specification of Patent No. 3133
June 23rd 1883 and the ends locked together by a stop on female acting as
previously described and engaging in slots, or holes, or recesses in a flange on male
end, or having the spring stop fixed on flange of male end and engaging with slots,
holes, or recesses in face of female part; when the screwed ends have been
sufficiently united by screwing one into the other, the spring stop having been
compressed by the male and female approaching, slips into a hole, recess, or slot
and locks them. To disconnect, the stop is forced back by the thumb or by a key
and the lock is broken and the coupling can be unscrewed. These couplings differ
from those now generally in use in so far that the stop is in such a position that
leakage of water from the joint of coupling, or water running out of the hose pipe
when uncoupled does not run into, or over the casing or recess containing the stop
and consequently is less likely to be thrown out of use by frost or sand washed in

page_text: them.
Moreover a coupling made in this manner without projecting lugs is better
suited for flaking and reeling, but swivel lugs can be added if desired.

JAMES CADOUX HUDSON 75 Upper Ground Street Blackfriars Road London
Engineer do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention has for its object the coupling together of hose 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 and one female.
Each part has a cylindrical portion grooved or otherwise and formed as may be
required for fixing on to it the hose or other tubing.
The cylindrical portion attached to the female can be made to swivel as in
ordinary screw couplings. The male and female ends of coupling are formed as a
bayonet joint and of similar shape to Figs. 13. 14. 15. 16 in the Specification of
Patent No. 3133 dated the 23rd June 1883 except that I can dispense with the

The rubber ring forming the joint is similarly arranged, but instead of placing
the spring stop in a position acting radially from the centre of bore of coupling,
I place it on the outer side of female coupling and acting on a line parallel with the

the female, by the collar on male end, and when the male end is turned within the
female the spring stop is forced into a hole or slot or recess in this collar when the
ends have been twisted into that position in which the bayonet joint will be
completed. There may be two three or more projections on the male end; and
the outer flange of female, behind which the projections on male are locked will be
cut away in two three or more places to admit the projections on male, and slots
holes or recesses will be formed in the collar on male of same number as the male
projections.
The coupling can be made by a part turn to the right or left. When
disconnecting the coupling the spring stop is pressed in with the thumb or by a
small key until the end clears the flange on male end and the male and female are
disconnected by a slight turn to right or left.
The spring stop can be placed on the flange of male end and the stop engage
with slots holes or recesses on the outer face of flange of female.
Also this spring stop can be used in connection with a coupling united by male
and female screw as in Figs. 5. 6. 7. 8. of the Specification of Patent No. 3133
June 23rd 1883 and the ends locked together by a stop on female acting as
previously described and engaging in slots holes or recesses in a flange on male
end, or having the spring stop fixed on flange of male end and engaging with slots
holes or recesses in face of female part; when the screwed ends have been
sufficiently united by screwing one into the other the spring stop having been
compressed by the male and female approaching slips into a hole recess or slot
and locks them there. To disconnect: the stop is forced back by the thumb or by
a key, and the lock is broken and the coupling can be unscrewed.
These couplings differ from those now generally in use in so far that the stop
is in such a position that leakage of water from the joint of coupling or water

Similar letters refer to similar parts in Figs. 1 to 7, and in Figs. 8 to 13, but
figures are attached to distinguish in the different modifications.
In Figs. 1. 2. 3 and 4 (C) is the male part of coupling, (D) the female, and on
each, parts (E. E) grooved or otherwise are formed to secure the hose pipe.
The male part (C) has projections (F) which with recesses (H) and projecting
flange (G), on the female (D) form a bayonet joint when the male end is entered
and turned within the female end.
A part (D2) contains the rubber washer (I) which makes a water tight joint
and revolves or swivels within the part (D¹) and in these respects is similar to
Specification of Patent No. 3133 of the 23rd June 1883. On the part (D') of
female I form a spring stop consisting of plunger (N) forced forward by spring (M)
and with part (L) of plunger projecting outside the cylinder or recess in part (D')
within which it is contained.
On the male eud (C) I form a flange (J) having recesses or notches (K) (K) (K).
When the male is entered within the female the flange (J) presses inwards the
stop (N) and in twisting the male and female partly round until the projections (F)
are behind the flange (G) as in Fig. 3; the spring stop then shoots out into one of
the recesses or notches in flange (J) and locks the male and female parts together.
The spring stop can be forced in by the thumb or by a key and the parts partly
turned and the coupling unlocked.
In Figs. 5. 6. & 7 the spring stop is shewn attached to flange (J¹) on male and
the recesses (H) formed in a flange on female part (D) the action of coupling and
uncoupling is similar to Figs. 1. 2. 3. 4.
In Figs. 8. 9 & 10 a screwed connection is formed to connect male (C¹) and
female (D³) and a spring stop (L') is formed in female (D³) which locks iuto a
recess (K) on flange (J2) on male when the two have been united and the male
has been screwed a certain distance into the female. The spring stop is compressed
by the advance of the flange (J) on male part and drops into recess (K³) when
the desired position is obtained and there locks the parts together. The coupling
can be disconnected by pressing in the stop and unscrewing the male and female
parts.

page_text: In Figs. 11. 12 and 13 a screwed connection is shewn similar to Figs. 8. 9 and
10 but the spring stop is connected to flange (J³) on male end (C¹) and locks into
recesses (K³) formed on flange (O) of female (D³).
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim.is
Firstly. The arrangement of hose or other coupling connected by screwed or
bayonet joint in connection with a spring stop the axis of which is parallel with the
axis of bore of coupling and working in a cylinder or recess attached to female
part of coupling the spring stop engaging and locking into a recess or recesses in
flange of male part as illustrated and described.
Secondly. The arrangement of hose or other coupling connected by screwed or
bayonet joint in connection with a spring stop the axis of which is parallel with the
axis of bore of coupling and working in a cylinder or recess attached to male part
of coupling the spring stop engaging and locking into a recess or recesses in flange
of female part as illustrated and described.
Thirdly. The arrangement whereby the spring stop is placed on the outer part
of male or female part of coupling and is not in connection with the interior bore of
coupling or the recesses or grooves therein thus avoiding the leakage into or filling
up with water so common in this class of coupling.
