"
JOSEPH HARTLEY, of Crank, near St. Helen's, in the County of Lancaster.
IMPROVEMENTS IN PIPES AND IN PIPE CONNECTIONS."
The improvements relate, firstly, to the manufacture of pipes of plastic or soft
material, and consist for their better preservation from injury and loss of shape in
supporting them while in a soft state in and by a removable jacket or jackets or
receptacles, lined or otherwise, made of any convenient material for the purpose of
carrying and holding said pipes prior to and during the time they are being finished
internally and at the ends, on or by a wheel or otherwise, and removed to the
drying room when said jacket or jackets are removed, leaving the pipe true in
shape. The improvements relate, secondly, to a method of joining or forming
connections between earthenware pipes and pipes generally, and consist of a flexible
metal strap or collar constructed in any convenient form, so that it can be drawn
or fitted round and embrace the ends of plain or butt ended pipes, said strap being
lined, or the pipes themselves supplied with a suitable packing of gaskin, rubber,
leather, lead, hemp, clay, cement, or other material, and so forming a tight joint
and one easily detachable when desired for lifting or removal of the pipes for any
purpose after the connections are made. The improvements can be conveniently
performed as follows, reference being had to the accompanying Drawing, which
illustrates a practical mode of performing the Invention; I do not however bind
myself to the exact modes illustrated, as they may be varied considerably without
departing from the nature of my Invention:-In said Drawing Fig. 1 is a side
elevation and Fig. 2 plan of a carrying jacket X which may be made of wood or
other material in two or more pieces, and lined with cloth, canvas, rubber, or other
substances if desired. Y are metal semicircular hoops or bands supplied with
clips Z for the purpose of holding the several pieces of the jacket X together when
embracing a pipe from the press or mill; when it is desired to remove the pipe the
D

page_text: clips Z are taken off, the hoops Y released, and the jacket opened. The jacket may
be of any convenient length and used for plain, butt ended, socket, or other shaped
pipes, and may be used for carrying a sufficient length of piping for being cut into
two or more pipes; curved pipes may be carried in the same way, the jackets being
formed in pieces to conform to their shape. Fig. 3 shows in perspective two butt
ended pipes D, D, joined by an improved flexible metal strap A, which may be
conveniently formed of galvanized hoop iron; Fig. 4, elevation of a tool and
tightening apparatus; Fig. 5, a plan of strap extended; and Fig. 6, side or edge
view of same.
To said strap is rivetted or otherwise fixed a shoe or heel piece B*
holding two threaded pins or studs E, over which the slotted end C of the strap is
to be drawn and secured by nuts, as shown in Fig. 3; the shoe is made wider than
the strap, as shown, and has projecting pieces B against which the tool for pulling
or drawing the strap tightly round the pipes may heel or take a purchase. The
mode of fastening shown is convenient, but the studs or pins and the slots may be
varied, also the mode of fastening and tightening used. Fig. 5 shows perforations
by means of which a packing or lining of gaskin G, Fig. 6, or other convenient
material may be secured to the strap.
In witness whereof, I, the said Joseph Hartley, have hereunto set my hand
and seal, this Eighteenth day of September, A.D. 1879.
