page_text: LETTERS PATENT to James Cadoux Hudson of 75 Upper Ground Street
Blackfriars in the County of Surrey Engineer for an Invention of "IMPROVE-
MENTS IN COUPLING HOSES AND OTHER PIPES "
PROVISIONAL SPECIFICATION left by the said James Cadoux Hudson at
the Office of the Commissioners of Patents on the 23rd June 1883.
JAMES CADOUX HUDSON of 75 Upper Ground Street Blackfriars in the County
of Surrey, Engineer. "IMPROVEMENTS IN COUPLING HOSES AND OTHER PIPES
This invention has for its object the coupling together of hose pipes such as are
used with engines but is applicable also for joining together other pipes which require
a connection readily made or separated. The improved coupling consists mainly of
two parts one male and one female. Each part has a cylindrical portion grooved
or otherwise or 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 part is formed with a screw thread cut upon it-the screw can extend
one or more threads or only part of a thread, or can be multiple threaded. The
female is tapped out to suit the thread on the male part-on the female there is a
stop, by preference a spring stop, although the spring may be dispensed with.
The stop is lifted by the point of the thread when screwing the male on and when
a certain position has been attained it engages with a recess cut in the thread or
part of male thus preventing the male and female unscrewing and becoming
detached unless the stop be withdrawn-which operation can be readily performed
by hand when necessary.
In another arrangement projections are formed on the end of the male part
which enter the female and the female is formed with an internal circular recess,
the outer flange of which is cut away at parts to allow the projections of the malo
to enter. The end of male having entered a certain distance by a twisting
movement the projections on the male are turned into the internal circular recess
in the female and beneath the flange. This joint is similar to a bayonet joint. The

page_text: male is arranged with a spring stop although as in the previous arrangement the
spring may be dispensed with which stop engages with a recess formed on the
male and prevents the male and female being turned or moved from the position
where the projection on the male engages with the recess in the female except the
stop be first withdrawn. The projection on the male is formed to lift the stop
when turned in putting the parts together. To render the joint watertight a
washer or ring is provided and the projections on the male can be inclined to
impart a forward movement to the male in locking the male and female together.

"
This invention has for its object the coupling together of hose pipes such as are
used with fire engines but is applicable also for joining together other pipes which
require a connection readily made, or separated The improved coupling consists
mainly of two parts one male and one female. Each part has a cylindrical portion
grooved or otherwise or 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 part is formed with a screw thread cut upon it--the screw can extend.
one or more threads or only part of a thread or can be multiple threaded. Tho
female is tapped out to suit the thread on the male part-on the female there is
a stop by preference a spring stop although the spring may be dispensed with.
The stop is lifted by the point of the thread when screwing the male on and when
a certain position has been attained engages with a recess cut in the thread or part
of male thus preventing the male and female unscrewing and becoming detached
unless the stop be withdrawn which operation can be readily performed by hand
when necessary.
In another arrangement projections are formed on the end of the male part
which enter the female and the female is formed with an internal circular recess
the outer flange of which is cut away at parts to allow the projections on the male
part to enter. The end of male having entered a certain distance by a twisting
movement the projections on the male are turned into the internal circular recess
in the female and beneath the flange. This joint is similar to a bayonet joint.
The female is arranged with a spring stop although as in the previous arrangement
the spring may be dispensed with-which stop engages with a recess formed on
the male and prevents the male and female being turned or moved from the
position where the projection on the male engages with the recess in the female
except the stop be first withdrawn. The projection on the male is formed
-

watertight a washer or ring is provided and the projections on the male can be
inclined to impart a forward movement to the male in locking the male and female
together
In order that my said Invention may be most fully understood and readily
carried into effect I will proceed to describe the Drawings hereunto annexed.

page_text: i
In this case the screw threads are dispensed with and in lieu thereof projections E E
are provided upon the part A and the part B¹ is made with an inwardly projecting
flange B*
This flange is notched away at parts corresponding to the projections E E and in
bringing the two parts of the coupling together the projections pass through the
notches provided in the flange B* to the inner side thereof. Then by turning the
part B the notches are carried around past the projections so that they cannot
again be drawn out.
B³ is a stop similar to that shewn in Figure 1.
As the part B' is turned round by the handles to lock the parts together, this 1
stop rides up the incline surface of one or other of the projections E and on
arriving in place it drops into a notch E' provided for the purpose in each of these
projections. So the parts of the coupling are locked and the part B¹ cannot be
turned in order to release them until the stop B* is intentionally withdrawn.
The head Do and the corresponding part at the outer end of the other handle is 1
able to turn freely upon the handle, this is convenient in winding up and unwinding
the hose from around the coupling.
Having thus described the nature of my said invention and the-manner of
performing the same I would have it understood that I claim :-
First Couplings substantially as described consisting of male and female parts 2
united by a screw or bayonet joint and having a spring or sliding stop on the
female part entering a recess in the male part and so locking the parts when
engaged that they cannot turn until the stop is first withdrawn,
Second-Couplings for hose and other pipes substantially as represented in the
annexed.drawings..
In witness whereof I-the said James' Cadoux Hudson have hereunto set my
band and seal this Twentyfirst day of December in the year of our Lord One
thousand eight hundred and eighty three.
