page_text: hereby declare the nature of this invention to be as follows:-
Made in the shape of a coller or band which passes around the Pipes. Inside
are cast or formed four tapering feathers two on each side in a direct line. The
Pipes to be coupled are made with two feathers on each end tapearing away to
nothing to correspond with those inside the Coupling. To make a joint you place
your right hand Pipe in position you then pass the Coupling over the end and
press in the packing ring then pass the end of the next section of Pipe into the
corresponding end of the Coupling. Attach the leaver give it one quarter turn
around more or less as may be required according to the thickness of Packing used
by which means it butts the Pipes and so makes the joint. The Coupling can be
adapted to every discription of Pipes from half inch up to six feet in diameter.
The principle claims for the Coupling joint or union is as followes The joint can be
made quicker than any other with less labour and without turning the Pipes.
In the event of the Pipes having stopages any section may be taken out without
breaking as in the old discription of joints thereby effecting a great saving to the
user. The Coupling dispences entirly with the old systum of bolts nuts and lead.
The folowing packing may be used at pleashure Elistic asbestos wood or Lead
Rings inserted between the ends of the Pipes. The small Pipes may be faced; or
cement red or white lead may be used. The Coupling can be adapted to the
smallest Hose Hydrand steam or water cock and can be conected and disconected
in less than one third the time occupied with the old systum of Coupling. it provides
a more direct passage for water or sanitary matter. the ends of the Pipes being
brought flush their is no stoppage at the joints as in other systums thereby the
chances of the Pipes chokeing up at the joints is greatly dimished owing to
them having a free passage through every section. After the joint is made it can
be locked with a wood key which makes it impassiable to come asunder under any
pressure.

An Improved Pipe Coupling, Applicable also to Hydrants and
the like.
I ROBERT BARKER of 12 Catherine Street, Whitehaven, Cumberland Butler do
hereby declare the nature of the said invention for AN IMPROVED PIPE COUPLING
APPLICABLE TO HYDRANTS AND THE LIKE and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement: -
The improved pipe coupling forming the subject of the present invention is
intended to obviate the employment of bolts, nuts, or lead soldering connections,
with the advantage that the joint is more readily made than hitherto, there being
no necessity to turn the pipes in making it, and in the event of choking or stoppage
of the pipes (which by the improved method is, practically reduced to a minimum)
any section can be taken out without breakage, which is both a saving in labour
and expense to those employing it.
This species of coupling is equally applicable to the smallest hose, hydrant,
steam or water cocks, the time occupied in connecting or disconnecting it is less
than that required by the old methods of coupling.
Fig. 1, of the accompanying drawings represents an end elevation of a coupling
of the description embodying my invention.
Fig. 2 is a plan of the same.
Fig. 3 being a cross section.
Fig. 4 a longitudinal section.
Fig. 5 showing the pipes in situ with intervening packing ring or washer.
The same letters of reference indicate like parts shown in the several figures.
Cast or otherwise fixed to the ends of the pipes in a direct line one with the
other are two tapering projections or feathers F, which fit into recesses H, of a
similar form made inside the collar C.
The coupling is effected in the following manner: one of the pipes say for
example with reference to the drawings, the right one B, is placed in position in
the recess or mortise H, in the collar C; an elastic or india rubber washer or
packing ring D, of wood lead or asbestos is then inserted, and the next pipe or left
band one A, is introduced in the collar in the same manner as the first, the ends
of each pipe are consequently pressed against the washer or packing as the case
may be.
Round the external circumference of the collar are a variable number of
projections E, for presenting a grip for a spanner, which is now applied to one of
them and turn more or less is given to the collar as may be required, according
to the nature and thickness of the packing employed, this brings the ends of the
pipes together and flush one with the other, the joint being now formed, wooden
wedges G, are inserted between the collar and pipe as shown by Fig. 2, which lock
the whole together and effectually prevent the pipes parting no matter what
pressure they may be subject to, by this means a perfectly hermetical joint is
formed and as already mentioned the ends of the pipes at the junction being

page_text: perfectly flush there can be no stoppage at the joints, a free passage being given to
the water or other fluid, thus the possibility of the pipes choking is practically
reduced to a minimum.
The same principle of construction is applicable to shafting and to pipes of any
diameter say from 1 inch to 6 feet. Small pipes may be faced with red or white
lead or cement at their junctions. For large pipes the number of tapering
projections or feathers is increased,
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what
I claim is:
The method of coupling pipes by means of a collar C, round whose external
surface are a variable number of projections E, whilst in its interior are two
tapering mortises H, for the reception of similarly shaped projections F, made on
the ends of the pipes to be coupled, and which are subsequently locked by the
wedges G, the whole in the manner and as, and for the purposes substantially as
herein described and as illustrated by the accompanying drawings.
