PROVISIONAL SPECIFICATION.
Improvements in Pipe Couplings.
I, JOHN VERDIN, of 17 Park Place, Eccles, Publican, do hereby declare the
nature of this invention to be as follows:-
The improvements relate to couplings for pipes, such as beer-engine pipes, fire-
engine and other hose pipes, and the like, and have for object to provide a coupling
which shall be more readily detachable than couplings for like purposes at present
in use.
To accomplish this, and to effect my improvements, I provide the two parts of a
coupling of suitable design and material, with spigot and socket, or male and female
ends, of ordinary construction, the spigot portion being formed with an annular
groove, or other indentations, and the socket portion being provided with latches or
bolts, projecting internally through apertures in the socket casing, so as to engage
with the groove or indentations in the spigot portion of the coupling, and so retain
the same in the coupled position, as will be well understood.
Attached to or forming part of these latches, bolts, or other projections, I
provide suitable levers, which are conveniently fulcrumed on the exterior of the
socket-casing, in such manner that, as the said levers are depressed at one end, by
the hand of the manipulator, the latches or projections at the other end are forced
apart, or outwards, thereby releasing the spigot and disconnecting the coupling.
The latches or bolts may be held in the coupling position by springs or other
elastic means, which springs may be caused to act either upon the latches direct,
or upon the levers actuating the same; and the said levers may be, and by
preference are, provided with suitable guards, to prevent any accidental and untimely
disconnection of the apparatus.
Variations in detail, such as in the method of attaching the pipes to the coupling
apparatus, the manner of mounting the levers and latches, the form of the springs,
and the design and material of the various parts, may be made without departing
from the peculiar character of the invention.

COMPLETE SPECIFICATION.
Improvements in Pipe Couplings.
I, JOHN VERDIN, of 17 Park Place Eccles, Publican, 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 :-
The improvements relate to couplings for pipes, such as beer-engine pipes, fire-
engine and other hose pipes, and the like, and have for object to provide a coupling
which shall be more readily detachable than couplings for like purposes at present
in use.
To accomplish this, and to effect my improvements, I provide the two parts of a
coupling of suitable design and material, with spigot and socket, or male and fernale
ends of ordinary or other construction, the spigot portion being formed with an
annular groove, or other indentations, and the socket portion being provided with
latches or bolts, projecting internally through apertures in the socket casing, so as
to engage with the groove or indentations in the spigot portion of the coupling, and
so retain the same in the coupled position, as will be well understood.

page_text: Attached to or forming part of these latches, bolts or other projections, I provide
suitable levers, which are conveniently fulcrumed on the exterior of the socket-
casing, in such manner that, as the said levers are depressed at one end, by the hand
of the manipulator, the latches or projections at the other end are forced apart, or
outwards, thereby releasing the spigot and disconnecting the coupling.
The latches or bolts may be held in the coupling position by springs, or other
elastic means, which springs may be caused to act either upon the latches direct,
or upon the levers actuating the same; and the said levers may be, and by
preference are, provided with suitable guards, to prevent any accidental and untimely
disconnection of the apparatus.
As a modification, the levers and latches may be mounted on the spigot, and the
recesses formed in or upon the socket; or projections may be formed upon the
spigot or socket, and the recesses may be formed in the levers, latches or bolts.
But that the improvements may be better understood, I will, with the aid of the
accompanying drawings, proceed more fully to describe means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1. shews the spigot and socket of a coupling in the connected position,
according to my improvements, and Fig. 2. shews the same apparatus disconnected,
the levers in this view being shewn in the position as depressed by hand, to effect
the lifting of the latches and release of the coupling.
The same letters indicate corresponding parts wherever they occur.
a. a. is the spigot, formed, in this case, with an annular groove a' for the reception
of the latches, though recesses or other means for obtaining a grip may be employed.
b. b. is the socket of the coupling provided with projections c. c, which support
the pins or other centres d. d. upon which the levers or latches e. e. are fulcrumed.
are hollow projections upon the socket, forming casings for springs 6' 6*
which springs tend to force apart the arms of the levers e. e. and so keep the latch-
teeth in the closed position.
g. is a rubber or other washer, against which the end of the spigot a. a. is caused
to press, when in the coupled position, and so effect a tight joint.
In coupling, the taper end of the spigot, by pressure from the operator, forces
apart the latch-teeth, until such taper end is moved past the teeth, when the
latter fall back into the annular groove, or recesses beyond, and the connection is
complete.
Slots or recesses are formed in the end of the socket for the free passage of
the latch-teeth, or, it may be, that such teeth project beyond the extremity of the
socket, in which case these slots or recesses are obviated.
Variations in detail, such as in the method of attaching the pipes to the coupling
apparatus, the manner of mounting the levers and latches, the form of the springs,
and the design and material of the various parts, may be made without departing
from the peculiar character of the invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
In pipe couplings, the combination of one end thereof with levers, springs, latches
or bolts, and the other end with suitable recesses or projections, for the purpose and
in manner substantially as herein shewn and described.
