We, DAVID LAW, JOHN LAW Junior, and JOHN LAW of the firm of J. and
A. Law, of Rae Street, Glasgow, Ironfounders, and JAMES JACKSON, of Chorlton-
cum-Hardy near Manchester, Traveller, do hereby declare the nature of this
invention to be as follows, that is to say:-
This Invention relates to fastenings for rain-water and other pipes and for pipe
heads and connections and more particularly to fastenings of the kind described in
the Specification of Letters Patent granted to the present applicants and dated
15 February 1884 N° 3349. The object of our present Invention is to improve
the fastenings, to facilitate their application in various cases, and to enable the
separation of any pipe-length or part of a series to be easily effected without
disturbing the entire series.
In carrying out the Invention we form on the pipe a snug or projection of a
dovetailed or other convenient form and we provide a socket into which to enter
this snug; but instead of the socket being formed in an earpiece which is directly
fixed to a wall or other structure, we form this socket in a movable piece which is
itself fitted into a socket or recess in the earpiece. This movable piece is by
preference formed with a stem passing down through the bottom of the earpiece,
and by means of this stem the movable piece can be raised, or moved outwards, in
such a way as to clear the snug of the pipe, and then the pipe-length can be
removed without its being necessary to first remove the pipe-length next above it.
Dated this fifteenth day of September 1885.

Applicants' Agent.

We, DAVID LAW, JOHN LAW, Junior, and JOHN LAW, of the firm of J. and
A. Law of Rae Street, Glasgow, Ironfounders, and JAMES JACKSON, of Chorlton-
cum-Hardy, near Manchester, Traveller, 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:-
Our said Invention relates to fastenings for rain-water and other pipes, and for
pipe heads and connections, and more particularly to fastenings of the kind
described in the Specification of Letters Patent granted to us the present
applicants, and dated 15 February 1884 N° 3349. The object of our present
Invention is to improve the fastenings, to facilitate their application in various
cases, and to enable the separation of any pipe-length or part of a series to be
easily effected without disturbing the entire series.
In carrying out our Invention we form on the pipe. a snug or projection of a
dovetailed or other convenient form, and we provide a socket into which to enter
this snug; but instead of the socket being formed in an earpiece which is
directly fixed to a wall or other structure, we form this socket in a movable piece
which is itself fitted into a socket or recess in the earpiece. This movable socket
piece can be raised or moved outwards in such a way as to clear the snug of the
pipe, and then the pipe-length can be removed without its being necessary to first
reinove or lift the pipe-length next above it.
And in order that our said Invention and the manner of performing the same
may be properly understood, we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing by way of example one form of our
improved fastening. In these drawings the same reference letters are used to
mark the same or like parts wherever they are repeated.
Figures, 1, and 2, are a plan and a front elevation showing a pipe, A, as secured
to an earpiece, C, with our improved fastening; whilst figures, 3, and, 4, are a plan
and side elevation of the pipe, A, by itself. Figures, 5, and 6, are a plan and
front elevation of the earpiece, C, by itself; figure, 7, is a vertical section of the
earpiece, C, with the movable socket piece, D, in its place; and figure, 8, is a back
elevation of the earpiece by itself. Figures, 9, 10, and 11, are a plan, a front
elevation, and a side elevation of the socket piece, D, by itself.
On the pipe, A, there is cast at the back a snug or projection, B, which is of a
dovetailed form in horizontal section, and which can be inserted into a dovetailed
socket made in a piece, D, which when in position practically forms part of the
earpiece, C. This socket piece, D, is of the form shown separately in figures, 9, 10,
and 11, and its upper part fits in a socket formed for it in the earpiece, C, whilst
a stem or leg, E, forming its lower part projects downwards through an opening in
the earpiece into a recess or space at the back of the earpiece. The socket
piece, D, can be cast separately and can be entered down into its place in the
earpiece. C.

page_text: When it is required to unfasten the pipe, A, the socket piece, D, is pushed up by
applying any convenient instrument to the bottom of its leg, E, a toe, F, preventing
it from being pushed up unnecessarily far; and it then gets clear of the snug, B,
on the pipe, A, and the pipe can be moved away without being raised. The
snug, B, is not made wedge-shaped as in the modifications described and delineated
in our earlier Specification herein before referred to, so that there is nothing to
prevent the socket piece, D, from being raised as explained.
The snug or projection, B, on the pipe, A, may be of any suitable horizontal
section such as any of those shown in figures, 7, and 10, of the drawings accom-
panying our earlier Specification, the socket in the socket piece, D, being of course
shaped to correspond. And the socket piece, D, instead of being made with a
stem, E, projecting downwards for raising it by, might be made with a projection
at its upper end of a form suitable for the application of a lifting instrument.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:—
The improved fastenings for rain-water and other pipes and for pipe heads and
connections, and consisting of a snug or projection thereon fitting a socket in a
socket pieco which is held in an earpiece but is movable therein for releasing the
snug or projection substantially as hereinbefore described.
