Improvements in Waste or Discharge Valves for Baths, Sinks, or
Jawboxes, Lavatories, and the like.
1, THOMAB LAW, of Sturrock Street, Kilmarnock, in the County of Ayr, North
Britain, Brassfounder, do hereby declare the nature of this invention to be as
follows, that is to say :-
My said invention has for its object the making of waste or discharge valves for
vessels in which water or other liquid is used or contained, in a better and less costly
manner than beretoforo.
By my invention I form the plug or valve and its socket or scating out of sheet
brass or other suitable sheet metal instead of casting them as hitherto commonly
done. The shaping of the socket piece or seating is done by means of suitable dies
and a screw press, hydraulic press, or other suitable pressing or stamping apparatus.
The holes made through the bottom of the seating to form a grating may be punched
at the same operation as the stamping of the other parts; or the holes may bo
punched at a separate operation. The plug or valve is similarly formed by means of
dies and suitable pressing or stamping apparatus; and it has subsequently riveted or
otherwise fixed to it.a centro piece having an eye for connecting the lifting chain to
it. The centre piece may be cast and turned or otherwise formed.

Improvements in Waste or Discharge Valves for Baths, Sinks, or
Jawboxes, Lavatories, and the like.
I, THOMAS LAW, of Sturrock Street, Kilmarnock, in the County of Ayr, North
Britain, Brassfounder, 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 :-
My said invention has for its object the making of waste or discharge valves for
vessels in which water or other liquid is used or contained, in a better and less costly
manner than heretofore.
By ny invention I form the plug or valve and its socket or seating out of
sheet brass or other suitable metal by means of suitable dies and a screw press
or other suitable pressing or stamping apparatus.
And in order that ny said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings,
to be hereinafter referred to, and showing, by way of example, one modification of
my improved valve, togethor with suitable dies for forming it.

page_text: Figure, 1, of the drawings is a sectional elevation of the dies, as applied in
forming the socket or seating.
Figure, 2, is a plan of the finished socket or seating.
Figure, 3, is a sectional elevation of the dies, as applied in forming part of the
plug or valve.
Figure, 4, is a plan of the finished plug or valve.
In these drawings the same reference lotters are used to mark the same or like
parts wherever they are repeated.
By my invention I form the plug or valve, A, and its socket or seating, B, out
of sheet brass or other suitable sheet metal instead of casting them as hitherto
commonly done. The pieces of metal out of which the plug, A, and socket, B, are
to be formed are round blanks stamped from a sheet of metal by dies (not shown)
consisting of an upper round punch and a lower block or bolster with an
opening in it the counterpart of the punch. The round blank for forming the
socket, B, is then placed in a recess, C, in a lower block or bolster, D, (Figures, 1
and 2) and it is shaped by a die, B, worked by a screw press, a hydraulic press,
or other suitable pressing or stamping apparatus (not shown). The holes, F,
made through the bottom of the socket or seating, B, to form a grating are
punched at the same operation as the shaping of the other parts; but the holes
may be punched at a separato operation. The plug or vulve, A, is similarly
formed by means of dies (, and H, (Figures, 3, and 4) and suitable pressing or
stamping apparatus (not shown); and it has subsequently riveted or otherwise
fixed to it a centre piece, J, having an eye and ring, K, for connecting the lifting
chain to it. The hole, M, in the plug, A, for, fixing the centre piece, J, into, is
punched during the shaping operation of the plug. The contro piece, J, may be
cast and turned or otherwise formed.
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 waste or discharge valves for baths, sinks, or jawboxes, lavatories, and the like,
forming the plug or valve and the socket or seating out of sheet metal by means
of suitablo dies and suitable pressing or stamping apparatus substantially as herein-
before described.
