We SAMUEL GEORGE MASON of Dale End Birmingham in the County of Warwick
Manufacturer and HENY HODKINSON of Frederick Road Aston in the same County
Manager, do hereby declare the nature of this invention to be as follows:-
This Improvement consists in the construction of an Union Joint which can be at
once applied in attaching piping or any other article requiring to be attached to taps
or connecting piping together and is particularly applicable for attaching the Patent
Grant Revolving Ball Water Filter to taps.
It consists in the construction of an Union Socket with or without an ordinary
outside screw thread and a tapering inside screw thread of steel or other hard metal
which will when screwed on to any softer material cut its own way thereon, and
become firmly fixed thereto. It may be used in connecting for instance two lengths
of piping in which case we can when desired form a union of a double inside reverse
thread each thread tapering towards the centre.

page_text: We SAMUEL GEORGE MASON of Dale End Birmingham in the County of Warwick
Manufacturer and HENRY HODKINSON of Frederick Road Aston in same County
Manager, 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, reference being had to the accompany drawings and to the
letters and figures marked thereon :-
This improvement has for its object the construction of an Union Joint which
can be at once applied in attaching piping or any other article requiring to be
attached to taps or connecting piping together. It consists in the construction
of an Union Socket of steel or other hard metal with or without an ordinary outside
screw thread, and with a tapering inside screw thread which will when screwed on to
any softer material cut its own way thereon and become firmly fixed thereto.
This construction of Union socket is particularly applicable for attaching the Patent
Grant Revolving Ball Water Filter to taps as it enables the filter to be attached to
existing taps without the removal of them for alteration.
It may be used in connecting for instance two lengths of piping in which case we
can when desired form an Union of a double inside reverse thread, each thread
tapering towards the centre.
Referring to the Drawings
Fig. 1. shews an ordinary tap Fig. 2. a section through one of our improved Union
sockets (a) is an outside screw thread which may be dispensed with when not
required (b) the tapering inside screw thread of steel or other metal of sufficient
hardness for the thread to cut its way (as indicated in dotted lines fig. 1) onto the
nozzle at (c) of the tap when the socket Fig. 2 is brought up to the tap Fig. 1 and
screwed onto it by means of the nut (d) formed on the socket.
Fig. 3 is a section through a Union socket (e) with the two tapering reverse
threads (f) of hard metal capable of cutting their ways onto the pipes (9) when they
are brought up to it and the socket (e) screwed on by means of the nut (h) and thus a
firm Union Joint formed.
We do not confine ourselves to the precise forms of sockets illustrated as these may
be varied to suit the requirements without affecting the principle of the invention.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. Constructing an Union socket with an internal screw thread of steel or other
hard metal capable of cutting its way upon taps or other articles to which it may be
attached substantially as herein set forth and specified.
2. Constructing an Union socket with two internal reverse screw threads of steel
or other hard metal for the purpose of connecting two ends of pipes or other articles
by the screw threads cutting their way onto the pipes or other articles all substantially
as herein set forth and specified.
