page_text: I, THOMAS FEATHER of Mirfield (via) Normanton in the County of York, Colliery
Agent, 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:
That is to say it relates to improvements in the jointings of pipes of the class
wherein the pipe and its jointings are integral, and consists of forming and constructing
same in such a manner that the coupling together thereof is greatly facilitated and
their jointings are rendered more secure against leakage of either liquid or gaseous
substances or in other words more certainly fluid tight.
This I attain in the manner hereinafter fully described in which description reference
is made by figures and letters, to the accompanying sheets of drawings illustrative
thereof.
Figs. 1 and 2 are longitudinal sections of portions of the two outer ends of a pipe
or of the contra distinctive ends of two pipes constructed according to my invention.
Figs. 3 and 4 are side and perspective views respectively, illustrating in each figure parts
shewn in section by figs. 1 and 2, as being joined together. Fig. 5 is a longitudinal
section enlarged scale of fig. 3. Fig. 6 is a section on line A B of fig. 5. Fig. 7 is a
detail drawing same scale as figs. 5 and 6, hereinafter referred to.
I construct the outer ends of the pipes a and b so that they shall form a socket as
well as a spigot end for each other, that is to say the outer end a¹ of the pipe a is
made so that it will enter the part of the pipe and the rim forming the part 6' of
the pipe is made so that it will enter the cavity a² formed by the hoop a³ being con-
structed or attached concentrically to the end a² of the pipe a.
Each of the outer edges c c² and c are somewhat of bevilled shape in order to fit
the correspondingly bevilled parts c³, cand e respectively, when the pipe a is
properly joined to the pipe b, each of said parts forming a kind of seating for its
corresponding part. Should it be thought desirable it will readily be seen that any
kind of packing, such as india-rubber (caoutchouc) cement etc. may be used as an
intervening medium between the above described seatings, or that these said seatings
may even be dispensed with and the outer edges, of the above described parts, made

page_text: straight, in which latter case the use of the packing above referred to will he
imperative.
On the pipe are formed the lugs or ears d (which may be two, three, four or more
in number as may be desired) and to these cars d are attached the hooks e, the same
being made so that they will engage with the projecting parts (which must corro-
spond in number to said hooks formed on the hoop a. In order to enable said
parts to thus engage with each other the openings are made so as to allow the
convergent ends of the hooks e to pass through and by means of the part-ƒ having
their edges somewhat of voluted or spirally inclined form, when the pipes a and b
are placed in such relative position that the hooks have passed through the openings g
it is only necessary to partially rotate one or the other of said pipes a or 6 to cause
same to be properly joined together, this bring effected by the combined actions of the
spirally inclined edges and the hooks us will be well understood.
To more certainly prevent leakage between the parts a and when joined together
as above described n suitably shapal op ming is made in the loop by and through
which, any suitably molten substance as lead, pitch etc., may he poured in order to fill
the cavity between the hoop und the rim forming the part .
The hooks are preferably attached to the lugs d by means of a screwed thread
being formel thereon and the nuts ec² used in connection therewith as illustrated so
that they will allow of ready adjustment; however it will be seen that these lugs may
bo otherwise attached thereto as by being rivetted or east.
In order to retain the pipes and in proper connertion when they are joined or
couples together as hereinlefore described, an annular piece of metal somewhat of the
form shown by fig. 4a is mounted upon the hoop a, as shown by broken lines fig. 3,
said piece of metal having on its outer edge suitably shaped notches and projections in
to engage with the outer ends of the projections and the hooks e thus holding same
in suitable relative positions. If it is thought desirable that the annular piece of metal
should be attached to the hoop so that same may not be reulily moved out of proper
position this may be done by means of set--crows as will readily be understood.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, I declare that what I
claim is:
1. The jointing of a pipe formed by one part, as the part al having seatings as
ate and a rim with voluted edges as at, in combination with another part as
the part which has seatings, lugs and hooks, said parts being arranged
and constructed to fit each other in order to form said jointing in the manner and for
the purpose substantially as specified.
2. The formation or construction of the jointings of pipes in such a manner that
each part shall form a socket portion for the reception of the spigot portion of the
other, said spigot and socket portions being drawn or forced into proper connection
with each other whether packing material is or is not used in combination therewith,
by the operation of voluto projections and gripping hooks, to the end substantially as
herein specificil.
