page_text: We, ALFRED COLEBY EMERY, of 30 Kynaston Road, Stoke Newington, in the
County of Middlesex, Gas and Water Engineer, and WILLIAM HENRY TYLOR, of
2 Newgate Street, in the City of London, Brass-founder do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particulariy described and ascertained in and by the following statement, reference
being had to the accompanying sheet of Drawings, and to the letters and figures marked
thereon, that is to say :-
The object of this invention is to produce a clip for fitting over or around a pipe
next the socket, to serve as a guard or temporary stopper to the space between the
socket and spigot into which molten lead or other jointing material has to be poured
to make a joint.
The clip is composed of a divided ring of asbestos, or other suitable material or
combination of materials, held in position round the pipe and close in front of the
socket by means of a chain, a band, or other suitable appliance, the ends of such chain,
band, or other appliance, being drawn towards each other by means of a screw, toggle-
joint, or other suitable appliance, for the purpose of putting the clip into close contact
with the circumference of the pipe and the face of the socket, so as to temporarily seal
or shut off the space between the spigot and the socket of two adjacent pipes, except
at the opening by or through which the molten lead is to be poured to run into the
said space.
In the Drawings hereto annexed, Figure 1 is an elevation of a clip constructed in
accordance with our invention as applied to the socket and spigot joint between
two lengths of pipe, and Figure 2 is a section of same on line x x of Figure 1.
;
A is the socket, and B the spigot, on the ends of two adjacent pipes C the annular
space, between the socket and spigot, intended to be filled with molten lead. D is the
body of the clip composed of asbestos, indiarubber, or other suitable flexible material.
We bave found, for example, that the material used for packing the glands of steam
engines, pumps. and such like, known as "Tuck's packing," is very suitable for the
purpose. This body D of the clip is enclosed within a metallic band E which may ho
rivetted, or otherwise secured, to the body D. To the ends of the band E are secured

page_text: (or formed therewith, if preferred) lugs FF, to one of which F is hinged a screw G
the free end of which takes into a slot in the other Ing F, and has-a nut H by scrow-
ing which on to the screw & the two lugs may be drawn towards each other, when the
clip is passed round the pipe, so as to press the internal surface of the clip body D close
against the outer surface of the pipe B, care being taken to press the clip close up to!
the face of the socket A as the nut L is screwed up. It is obvious that other devices
may be used for pressing the internal surface of the clip D closoly against the outer
surface of the pipe, such as a flat-link chain for example; and that, instead of n serow
and nut, a toggle joint, or a lever, latch, or hook, for example, may be employed to
produce the necessary pressure to draw the two ends of the band, or chain, towards
cach other.
It will now be understood that, when the clip is placed in the position shown in the
Figures, the space C will be closed in front, except at the upper part where the space
between the two ends occurs. A small piece of clay applied at this point completes
the continuity of the clip for the time being while leaving room for the molten lead to
bo poured in to fill the space (. When this is done, and the lead has set, the clip is
unfastened and removed from the pipe. To prevent the load from burning the clip D
when the same is made of materials Umt would be burned or scorched by molten lead,
the said clip is occasionally damped with water which effectually prevents burning or
scorching of the surface.
By the use of our invention, lead joints may be made in pipes without the usual
stopping of clay except at the point where the lead is poured into the space, and, in
some cases the clip may be so formed at its ends that they will fit one into
the other son to forin a continuous clip without requiring the use of any clay
at all.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is -
The improved appliance for use when jointing pipes with lead, or other jointing
material, constructed and applied substantially a-hereinbefore de cribed, and illustrated
in the Drawings hereto annexed.
