Office of the Commissioners of Patents on the 4th August 1881.

"IMPROVEMENTS
IN APPARATUS OR MECHANISM FOR MAKING OR FORMING TRAPS FOR WATER
CLOSETS, BATHS, SINKS, AND OTHER PURPOSES."
This Invention consists of two machines on one bed plate for casting lead traps
in two pieces, having only one seam or joint, which I intend to burn or solder
together, making a complete trap with a flange outside for fixing.
In carrying out my Invention I adopt mainly the following arrangements on a
bed plate, which I prefer to be of an angle shape; on one half this plate I fix a
bracket or carriage with a rack and pinion inserted in same to be worked with a
wheel or handle; on the same plate I fix one part of mould, with I prefer being of
an angle shape, at the lower part of the now fixed angle mould; I fix another
piece of mould on joints or hinges and pins; upon the last named piece I place or
fix another piece of mould forming the top part of mould; at the end of the above
mentioned rack I fix a horizontal maundrill forming the inlet and dip pipe, the
other part of mould forming half the out go and forming one half of the trap
complete with flange, which I claim as useful. The mould has suitable openings
for pouring in the lead or other metal. To form the other half of trap on the first
named bed plate I have four or more holes; on this I fix a complete block in one
piece to form the internal part of second half trap; around the block I fit a frame,
which can be raised or lowered, so as to lift the half trap off the block or to be
dll....מ

page_text: taken off by hand; on the under side of frame above mentioned I fix four or more
unless bolts or rods, which are connected to another plate, which can be raised or
lowered with the frame by means of screw or wheel and pinion, or can be raised
by means of one or two crowbars as required; upon the above mentioned frame I
fix two quarter moulds, which are connected by hinges or pins, being the shape of
the outer part of half trap; in casting the half trap the sliding frame and under
plate with the two quarter moulds are lowered; the two quarter moulds are closed
and secured by cramp; the lead or other metal is then poured in by suitable
openings; the moulds are then opened, the frame is raised, and the half trap is
loose from its block, ready to be connected to the first mentioned half; the trap
can be made, leaving an opening at the bottom with a thread cast therein for
cleaning purposes, into which a screw plug is screwed, closing in the opening.

CHARLES PARKER, of Amberley, in the County of Middlesex. "IMPROVEMENTS
IN APPARATUS OR MECHANISM FOR MAKING OR FORMING TRAPS FOR WATER-
CLOSETS, BATHS, SINKS, AND OTHER PURPOSES."
This Invention consists of two apparatuses or machines on one bed plate, whereby
I am enabled to form or make a trap in two pieces having only one seam or joint,
which I burn or solder together, making a complete trap with flange outside for
fixing same.
In carrying out my Invention I adopt mainly the following arrangements :-
On a bed plate, which I prefer of being of an angle shape at one end, at the angle
end of bed plate c I fix one part of the mould, which I prefer being of an angle
shape, the interior of the same being hollowed out to form a part of inlet s¹ and
outlet 8 of trap; at the lower part of the now fixed angle piece I fix another piece
of mould on joints or hinges or pins x, the interior part fitting the last mentioned
piece forming part of the flange; upon the last named piece I place or fix another
piece of mould forming a part of the top of mould y with the other part of flange
with half the runner opening; the other half top of mould with part runner
opening, I place or fix on top of the first mentioned angle mould, with joints or
hinges or pins t at a suitable distance from the angle part of the bed plate; I fix a
bracket or pillar m, with a pinion'n and a spindle inserted in same, which can be
worked by a wheel p or handle; I then form a rack o for the pinion n to work in.
At the end of this rack I fix a horizontal mandril q, which can be worked backwards
and forwards into the first mentioned mould 8, forming the inlet and dip pipe;
this part of mould can be placed on its side with the runners at suitable places.
At the sides of the two top pieces of mould I fix two handles 7, 7, which forms a
latch to keep the mould together while metal is being poured in, also used for
opening same, and one r on the other part of top mould used also for opening
mould. In casting this half the mandril q is withdrawn, the handles raised, which
opens the mould and the casting to be taken out and mould replaced. To make or
form the other half trap, on the first named bed plate c I have two or more holes
as required; on this plate I fix a complete block in one piece e to form the
internal part of the bottom half of the trap with part of outgo. Around the lower
part of this block I fit a frame f, which can be raised so as to lift the half trap off of
the block and lowered as required on the under side of frame by means of a screw,
or the same can be raised or lowered by means of an eccentric with blocks and
slides; these appliances of raising and lowering can be fixed on the top part of
frame instead of at the bottom or can be raised by means of two small bars fitted
in suitable openings. Upon the above mentioned I provide suitable joints; I then
connect to this frame two quarter moulds d, d, being the shape of the outer part of
the bottom half trap, having suitable openings for pouring in the metal; this part
of mould can be made to form an opening in the bottom of trap for cleansing
purposes with a screw cast therein with a suitable plug to screw therein. In
casting this half trap the frame f is lowered on to the bed plate c, the two quarter
moulds are closed and secured by a cramp ; the metal is then poured in at the suitable
openings; the two quarter moulds are then opened and the frame raised, leaving
the half trap loose on its block, and the mould is closed up again and the frame
lowered and is ready for use.
For some purposes I can modify my arrangements by moving my solid block
and raising that to a suitable height; with a suitable piece also I can lengthen the
.

page_text: quarter moulds to suit the height of the block, which will enable me to cast a trap
with a flange at the top of outlet by removing several pieces in my angle moulds
and introducing several additional parts I will be enabled to cast a cover with dip
and inlet pipes for the above mentioned bottom parts.
Figure 1 is the front elevation; the dotted lines will show the interior of the
mould constructed according to my said improvements.
Figure 2 is a plan of the same, which will be seen by the dotted lines, as in
Figure 1.
Figures 1 and 2 are marked with same letters with reference to several parts;
a, a, are two stands on which the bed plate c is supported; d, d, are the two
quarter moulds; e is the solid block forming bottom part of trap; ff, is the frame
that surrounds the block and support the two quarter moulds; g. 9, 9, 9, are the
pins forming part of the joints; h, h, are studs fitted with nuts; jis a plate
connected to studs; k, screw for raising frame; l, a hand wheel; m, bracket to
support pinion and rack; n, the pinion; o, a rack; p, a hand wheel; q, showing
the horizontal mandril; r, r, 1, showing three handles, two of which are used for
fastening mould together; s is an angle part of mould forming part of the inlet
and outgo; t is the upper part of mould forming the other part of inlet;
u, u, u, are brackets to support the last mentioned piece; w, w, w, showing pins for
connecting same together; x, x, is a part of angle mould forming a part of dip
pipe and flange; y, y, is another upper part of mould forming part of dip and flange.
Having now. described the nature of my said improvements, and in what manner
the same are to be performed, but as the said improvements are capable of various
modifications without departing from the principle thereof, I do not restrict myself
to the precise form or number of the several parts; what I claim as my Invention
is the construction of moulds in sections for the production of castings of lead or
other suitable metal or material for making or forming traps for water closets,
baths, sinks, and other purposes, as also the apparatus or mechanism connected
therewith, as herein before described and illustrated, or various modifications
thereof.
In witness whereof, I, the said Charles Parker, have hereunto set my hand
and seal, this Twenty eighth day of January, in the year of our Lord
One thousand eight hundred and eighty two.
