Improvements in Pipe Couplings for Railway and other Vehicles.
I, JAMES TRANTER, of 15, Pickering Street, Hoole, Chester, Fitter, do hereby
declare the nature of this invention to be as follows:
Two short pipes made in brass, gun metal, steel, iron or other suitable material
are provided for coupling together the pipes used in connection with heating
apparatus, brakes or other requirements of railway or other vehicles. These two
pipes are made with a flange or collar at one end, which flanges are so truly faced
that when brought together with sufficient pressure they make a perfectly tight
joint, and thus prevent the escape of steam, gas, air, water or other liquid, fluid
or vapour.
In order to apply the pressure necessary for making and keeping
the joint perfectly tight between the before mentioned flanges or collars each
short pipe is provided with a loose collar having a rim made solid with it, and
extending for nearly one half its circumference, so that when the two loose collars;
i.e.:-
-one on each short pipe-are brought together, each half rim laps over
the edge of corresponding collar, and thus forms a complete encircling of the
collars on end of each short pipe. To the outside face of these loose collars a
stud or fulcrum pin is secured, and to these fulcrum pins two strap or clip levers
are attached and their form is such, that as their outer ends are pressed
nearer each other, they force the loose collars and through them the faces of fast
collars on ends of short pipes together, and that with such pressure as to make
a perfectly tight joint. Provision is also made for securing the ends of levers
in positions required by means of links and hooks, and these being readily
released, the couplings are at once set free and disconnected.

I, JAMES TRANTER, of 15, Pickering Street, Hoole, Chester, Fitter, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-

the joint perfectly tight between the before mentioned flanges or collars each

extending for nearly one half its circumference so that when the two loose collars
i.e. one on each short pipe are brought together, each half rim laps over
the edge of corresponding collar and thus forms a complete encircling of the
collars on end of each short pipe. To the outside face of these loose collars a
stud or fulcrum pin is secured, and to these fulcrum pins, two strap or clip levers
are attached, and their form is such that as their outer ends are pressed
(nearer each other) they force the loose collars, and through them the faces of fast
collars on ends of short pipes together, and that with such pressure as to make
a perfectly tight joint. Provision is also made for securing the ends of levers
in positions required by means of links and hooks, and these being readily
released, the couplings are at once set free and disconnected.
In the drawing the short pipes, to which the pipes to be connected are attached,
are marked A, the collars on same B, and the loose collars with rim C, the fulcrum
pin D, and the strap or clip levers E.
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:
1. The combination of the parts forming the complete coupling, and consisting
of the short pieces of pipes with fast collars, the loose collars with encircling rim,
and the strap or clip levers with their respective fulcrum pins.
2. The special form of the various parts forming the complete coupling, by
means of which the pressure forcing the faces of loose and fast collars together,
is such as to provide a perfectly tight joint.
