PROVISIONAL SPECIFICATION.
Improvements in Unions or Couplings for Pipes.
I, EDWARD WILFORD of 8 Tudor Grove, Nottingham, in the County of
Nottinghamshire, Ironmonger, do hereby declare the nature of this invention to be
as follows:
This invention relates to a coupling joint or union for connecting together
metal, rubber or other pipes, in conjunction with a removable cone joint, thereby
dispensing with all kinds of packing, and consists of parts as shewn in the
accompanying drawings.
Fig. 1 shows in section a union fitted according to my invention, one end of A
is recessed to admit one end of B which is bored taper to fit a cone C secured at
either make in the solid
bottom of recess formed in A. This taper end of B
as shewn, or make it movable as in C; these parts which are easily renewable
may be made of metal or other suitable material. Upon the outside of A is
placed a ring D held in position but allowed to move freely round same.
end of B are placed two or more lugs or projections Fig. 1, corresponding
slots e e being cut out of A to receive them, similar slots ff are cut out of ring D
also to allow projections to pass through.
At one
Fig. 2 is an end view of part A shewing position of ring D and slots e e
and opposite to each other necessary to allow projections & upon part B
being inserted and fitting to coue C.
Figs. 3 and 4 shew position of ring D when joint is fastened, this operation
being effected by the ring D having two or more taper faces working against a
corresponding number of projections bb, forcing and holding taper recess formed
in B against cone C Fig. 1.
When applying my invention to unions it will be obvious that other devices
for securing cone C in recess of A may be used, and also that the outer ends of A
and B may be of any other design than that shewn in the drawings so as to suit
various descriptions of pipes without departing from the principle of my
invention.
The advantages claimed for this invention are that a perfectly steam tight
joint may be instantly obtained without the use of any kind of tools or packing,
and that the wearing parts are readily renewable.
Dated this Eighth day of September 1890.

COMPLETE SPECIFICATION.
Improvements in Unions or Couplings for Pipes.
I EDWARD WILFORD of 8 Tudor Grove, Nottingham, in the County of
Nottinghamshire, Ironmonger 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 :-
The object of this invention is to afford a means for readily renewing the
wearing parts or faces which form the joint in unions or couplings for pipes and
at the same time dispensing with washers or any kind of packing, as a perfectly
steam or water tight joint can be made without the use of either.
My invention consists of a cone which is screwed or otherwise secured in the
one half of a union, and a receptacle for the cone which is affixed in the other
half of union, this receptacle may be made solid to the remaining part of the half
CDC1

page_text: union or may be made separate and then secured either by a screw or other means;
these two parts are ground to fit each other perfectly and when brought together
make a tight joint, they are also made shaped inside, probably hexagonal, so that
when worn they may be easily taken from the union to which they are attached
and again reground, or replaced by new ones, these parts are unde in metal or
other suitable material.
The drawing which were left with the Provisional Specification" shew the
external parts of a coupling now in use, and also shew the manner in which the
removable come jomt may he applied to the same, the description hereinafter
contained describes how this particular muion is made and manipulated but the
cone joint is the same when applied to any union, irrespective of the means employed
for connecting the two halves of a union together.
Fig. 1 shews in section a union which has a come joint fitted to it according to
my invention, one end of A is recessed to admit one end of 13 which is bored taper
to fit a come C. secured at bottom of recess formed in A, this taper end of B is
either solid as shewn or moveable as in ('. Upon the outside of A is placed a
ring 1 held in position but allowed to move freely round same. At one end of B
are placed two or more lugs or projections 44 Fig. 1, corresponding slots e e being
cut out of A to receive them, similar slotsfare ent out of ring D also to allow
projections && to pass through,
Fig. 2 is an end view of part A shewing position of ring D and slots ee and ƒƒ
opposite to each other necessary to allow projections 66 upon part B being inserted
and fitting to come ('.
Figs. 3 and 4 show position of ring 1 when joint is fastened, this operation being
effected by the ring D having two or more taper faces working against a corre
sponding number of projections 4 b forcing and hohling taper recess formed in 153
against cone C', Fig. 1.
When applying my invention to unions it will be obvious that other devices for
securing cone (in recess of A may be used and also that the external parts and
outer ends of A and B may be of any other design than that shown in the
drawings.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A removable cone and a receptacle for the same, the cone to be secured to the
one half of ion by a serew or other means and the receptacle to be either solid
to the half of union or moveable in the same way as the cone, and that the removable
cone and receptacle may be fitted to any union for coupling pipes, making a
perfectly steam or water tight joint without the use of washers or packing of any
description, and can be readily removed and renewed without injury to the other
parts of the union.
Dated this Sixth day of June 1891.
