COMPLETE SPECIFICATION.
Improvements in the Formation and Construction of the Jointings
of Pipes.
I, THOMAS FEATHER Stone Merchant Waverley House Knowle Road Mirfield
Yorks, 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 Jointing of Pipes of the class where-
in the Pipe and its Jointings are integral, and consists of forming anu con-
structing the 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, and
thereby is calculated to create a great saving by the prevention of leakage.
Moreover the manner in which this Joint is formed is calculated to create a
great saving of time, lead, and other material, besides making a superior and more
secure Jointing as compared with the usual practice of forming the Jointings of
Pipes for the conveyance of Gas, Steam, Water, &c., &c.
2. This I attain in the manner hereinafter fully described, in which description
reference is made by figures and letters to the accompanying sheet of drawings
illustrative thereof.
3. Letters A & B are longitudinal sections of the Pipes constructed according to
my Invention, letters D. & E, are side and perspective views respectively, illustrat-
ing in each letter the parts being jointed together.
The three surfaces, viz:-5, 10, and 15, forming a triple joint at one operation
by the insertion of rings or other material, which may be composed of India
Rubber, Paper, Lead, or any other suitable substance, and the greater the internal
pressure is, and the more secure and tight the joint becomes.
4. I construct the outer ends of the pipes D. & E, so that they shall form a
socket as well as a spigot end for each other. That is to say the outer end A 1 of
Section B, is made so that it will enter the part A 2, of the Pipe A, and the rim
forming the part B 1, of the Pipe A is made so that it will enter the cavity of B2,
formed by the hoop A 1, being constructed or attached concentrically to the end
section B. The surface C1, of the flange D, forming a third joint at C2, making a
triple joint.
5. These three seatings, 5, 10, & 15 may be turned to fit exactly their correspond-
ing parts and thereby dispense with the necessity of packing, forming, (with a
little White Lead) a completely tight joint.
6. In order to retain the Pipes A, & B, in proper connection when they are
jointed or coupled together, as hereinbefore described I have square holes cast in
the two flanges D. & E. so as to receive square bolts which may be screw or cotter
bolts as F, through which is a hole at G, to receive the Cotter H, which when
driven home draws the two Sections A. & B. with their respective seatings, tightly
together, forming one complete triple joint.

page_text: This principle will apply to any diameter of Pipe by increasing the number of
Cotter or other Bolts. These Pipes may be made of Earthenware, Iron, Steel or
other Material, and for Earthenware Pipes the Cotters may be made of wood.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
1. The Jointings of Pipes formed by one part, as part C1, Section A, having
seatings as at C2, Section B, and a rim, as A1, in combination with another
part A 2, on which is another rim B 1, which has seating as at B2, the said parts
being arranged and constructed to fit each other, in order to form the 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, the said spigot and socket portions being drawn, or forced into proper con-
nection with each other, whether packing material is, or is not used in combination
therewith, by the operation of the Volute Cotter being driven through the hole
left for that purpose in the Cotter Bolts, or which may be Screw Bolts, by which
process the two flanges are gripped together, forming a completely tight joint as
herein substantially specified.
