Improvements in or relating to the Waste and Overflow Apparatus
or Fittings for Lavatory Basins and the like, and in the
Manufacture of Parts thereof.
I, JOHN JOHNSTON WILSON of 61 Buccleuch Street, Edinburgh, in the County
of Midlothian, North Britain, Plumber and Sanitary Engineer, do hereby declare
the nature of this invention to be as follows:
This invention relates to improvements in or connected with the waste and
overflow apparatus or fittings for lavatory basins and the like, and in the
manufacture of parts thereof.
The first part of my invention, consists in making and combining certain parts of
Baid fittings forming the main discharge waste and overflow passages with screwed
basin, and trap connections integral, so as to provide a more efficient, simple, cheap
and complete sanitary system in fitting up, suitable for being openly exposed to
view and also for the production of a finished article from the mould or casting.
Said apparatus or fittings is or are equally applicable to all kinds of wash hand
basins and the like having a separate overflow and discharge waste passage in which
such overflow and waste passage are not combined or made integral with the basin
except the nozzle or horn of the overflow, but my invention more particularly refers
to such basins having a recess formed in the back thereof or such as have the
discharge outlet situated conveniently near the back of basin.
My invention also relates to improvements in the waste pull and plug arrange-
ment, and consists in modifications of as well as additions to the invention described
in the Specification of Letters Patent No. 12,707 of 11th July 1892 granted to me.
In carrying out the first part of my invention I make the parts. forming the main
discharge waste and overflow passages with screwed basin and trap connections all
integral in the shape of a combined curved branch and bend which is by preference
cast in lead or any other suitable metal or alloy capable of being cast in chilled or
iron moulds that is to say in metal or in plaster or other suitable moulds with
provided with a forced
segment draw or other cores; the said integral casting
screw thread socket or connection (made after the manner of the well known
screwed sockets for paraffin lamp burners) in which the forced screw thread is
secured in the process of casting by the molten lead or other metal solidifying
round the socket and forming a screw thread encased with a forced brass or copper
screwed socket or connections.
The said forced screw thread is preferably made from sheet brass or copper and
may either be struck or spun up to the shape required and may be treated to a
series of annealing processes if necessary for the easier accomplishment of forming
the forced screw thread on a screwed mandrel and die or any other suitable
device.
The said screwed sockets may be held in position or supported in the mould by
the core or print or by a master screw or hollow mandrel which is withdrawn after
the casting. The said screwed socket at the point of contact only, may be tinned
or otherwise prepared in order to prevent the possibility of the cased screw thread
from turning. Both the waste and overflow passages communicate with a trap
below and the overflow passage is preferably situated in a straight vertical
position under the nozzle or horn of basin.

page_text: The said trap may be made either of lead or brass and connected with the
casting by a union or coupling of the washer type or any other suitable connection
thereby allowing the outgo of the trap to be placed or turned in any desired
direction. The screwed nut for the union or coupling may be treated in the same
or similar manner in the process of casting (as hereinbefore described) or it may
be made of cast brass, with a cut screw thread and brass tail, and the plug socket
which forms an accessory part of the basin connection may be made of cast brass
or other suitable metal with a cut screw thread corresponding with the forced
screw thread socket. The said waste and overflow apparatus when made in lead
or other equivalent metal or alloy may be painted with metallic enamel paint or
otherwise treated.
I may provide said plug socket with a long screwed tail having a shoulder nut
with check screw under the flange of plug socket for the purpose of adjusting or
regulating the depth or distance of same relative to the plug rod or pull in order
to suit the usual variations of depths of basins effected in the process of drying
and in kilning such pottery ware, the discharge outlet of basin is made with a deep
rounded or countersunk socket with shoulder for the reception of the said plug
Focket as described. Another method is providing a screwed basin connection
with a screwed socket for a separate screwed plug socket and loose grating.
I may provide a projecting ear or wing fixed or cast on the back of the overflow
passage for securing to the back wall or framework of lavatory stand for the
purpose of supporting the weight of the combined curved branch and bend from
the basin. I purpose also casting a flange on the top of the bend forming part of
the waste passage for the basin connection suitable for an encased rubber washer
or other plastic material.
As regards the part of my invention forming the waste pull and plug arrange-
ment, I provide an adjustable back or scle plate having a sliding bolt for fixing
the guiding socket to the top of the cabinet basin also providing the back plate
with a recess or cavity for the reception of a ✓ slot for a sliding bolt with head
correspondingly shaped, or in a similar manner to a dovetail, or instead it may
have a square shoulder.
The said adjustable back plate has the V slot or bed for the sliding screwed
bolt and nut cast in one piece of brass or other metal, a little distance up from
the edge or bottom of the recessed back plate so as to provide for the reception of
an encased washer, or the bedding of putty or other plastic material for fixing
the guide socket to the top of basin.
Also the said sliding screwed bolt having the V or dovetailed head corre-
sponding with the V slot is preferably made of cast malleable iron for greater
strength. also provide a check screw at the back of the back plate for locking
or binding and so preventing the possibility of the sliding bolt becoming loose
from any undue strain or vibration. The guide socket is secured to the back
plate by a large headed check screw and washer situated under the rubber buffer
which is easily removed for repairs or cleaning purposes by springing the said
buffer out of its encased position and unscrewing said check screw. The guide
socket is also recessed for the reception of the front tail piece of the back plate.
My invention also consists in forming the knob or handle with a check joint
which is thrown or falls back and rests on the buffer both in its normal position
when closed and also the reverse as described in the former Letters Patent when
held open.
The modification of the straight rigid rod for turning the valve
horizontally to the side of the plug socket is thrown and rests only on the buffer
in its normal position when closed, the object in both cases is to place it still
further out of the way of the user.

Improvements in or relating to the Waste and Overflow Apparatus
or Fittings for Lavatory Basins and the like, and in the
Manufacture of Parts thereof.
I, JOHN JOHNSTON WILSON, of 61 Buccleuch Street, Edinburgh, in the County
of Midlothian, North Britain, Plumber and Sanitary Engineer, 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:-
This invention relates to improvements in or connected with the waste and
overflow apparatus or fittings for lavatory basins and the like, and in the manufacture
of parts thereof.
The first part of my invention consists in making and combining certain parts of
said fittings forming the main discharge, waste and overflow passages, with screwed
basin and trap connections integral, so as to provide a more efficient, simple, cheap
and complete sanitary system in fitting up, suitable for being openly exposed to
view and also for the production of a finished article from the mould or casting.
Said apparatus or fittings is or are equally applicable to all kinds of wash hand
basins and the like, having a separate overflow and discharge waste passage in
which such overflow and waste passages are not combined or made integral with
the basin except the nozzle or horn of the overflow, but my invention more
particularly refers to such basins having a recess formed in the back thereof
or such as have the discharge outlet situated conveniently near the back of
the basin.
My invention also relates to improvements in the waste pull and plug arrange-
ment, and consists in modifications of as well as additions to the invention
described in the Specification of Letters Patent, No. 12,707, of 11th July 1892,
granted to me.
But in order that my said invention may be more readily understood and easily
carried into effect, I will describe the same with reference to the accompanying
drawings.
Figure 1 is a front elevation, shown partly in section, Figure 2, a side elevation
also shown in section, and Figure 3 a plan of a lavatory basin having my
improvements attached.
Figure 4 is a part sectional elevation and Figures 5 to 7 are detail views
hereinafter referred to.
In carrying out the first part of my invention I make the parts forming the main
discharge or waste A and overflow passages B with screwed basin and trap
connections all integral, in the shape of a combined curved branch and bend C,
which is by preference cast in lead or other suitable metal or alloy which is
capable of being cast in chilled, iron, metal, plaster or other suitable moulds, with
segmental draw or other cores. The said integral casting or branch and bend C is
provided with a forced screw thread socket or connection D (made after the manner
of the well known screwed socket for paraffin lamp burners) in which the forced
screw thread or socket D (shown more particularly in Figure 5) is secured in the
process of casting by the molten lead or other metal or alloy solidifying round the
said socket piece D and forming an encased brass or copper screwed socket or
connection.
The said screw portion D (Figure 5) is preferably made from sheet brass or
copper and it may be either struck or spun up to the necessary'shape, and if desired
it may be subjected to an annealing process or processes so as to enable the
screwed thread being forced by means of a screwed inandrel and die or other
device.

page_text: The screwed socket D may be held in position or supported in the mould by
means of the core or print or by a master screw or hollow mandrel which is
withdrawn after the casting of the said socket. At the point of contact the
socket D may be tinned or otherwise prepared in order to prevent the possibility of
the said cased screw socket D from turning. Both the waste A and overflow B
passages communicate with a trap E below, and the overflow passage B is preferably
situated in a straight vertical position, as shown, under the nozzle or horn F, of
the basin G, which is formed or provided at the back of the said basin G.
The trap E, which may be made of lead or brass, is connected to the casting C
below the junction of the waste and overflow apparatus by means of a union or
coupling H preferably of the washer type, or it may be otherwise connected, so as
to enable the outgo of the said trap E to be placed or turned in any desired
direction. The screwed portion of the union nut H may be treated in the same, or
in a similar, manner, as herein before described in the process of casting; or if
desired the union H may be cast in brass, with a cut screw thread and tail piece.
Also the plug socket J, which forms an accessory part of the basin G may be made
of cast brass or other metal with a cut screw thread corresponding with the forced
screw thread in the socket D. The waste and overflow apparatus when made in
lead or other metal, or alloy, inay be painted or coated with metallic enamel paint
or otherwise treated.
The
The plug socket J may be provided with a screwed tail piece having a shoulder
nut and check screw provided, preferably under the flange of the said socket J for
the purpose of adjusting or regulating the depth or distance of the said socket
relative to the plug rod or pull K so as to suit the variations in the depth of the
basins caused by the drying and kilning processes of such pottery ware.
discharge outlet of the basin G is made with a deep rounded or countersunk recess
or pocket having a shoulder for the reception of the said plug socket J. Or as a
modification may employ a screwed basin connection with a screwed socket for a
separate screwed plug socket having a loose grating.
Also in accordance with my said invention I may form or provide the branch
piece C with an ear or projecting wing L at the back for securing the said
branch C to the wall or framework of the lavatory stand so as to support the
weight of same. Also if desired I may form or provide the branch piece C with a
flange M on the top of the end, which forms the connection with the waste pipe A,
and I may so form the said flange M as to enable a cased or other rubber or other
plastic material washer to be used.
As regards the part of my said invention referring to the waste pull and plug
arrangement, I provide an adjustable back or sole plate N (Figures 4 and 6) having
a V shaped slot or bed n formed in a recess or cavity a little distance up from the
edge or bottom of the said plate N so as to provide for the reception of an encased
washer or bedding of putty or other plastic material employed for fixing the said
plate N to the top of the basin G. The said back plate N is retained in position
by means of a bolt P having a V or other shaped head to correspond with the
slot or bed n in which it works after the manner of a dovetail or similar
joint; said bolt P is preferably made of malleable cast iron for greater strength.
In order to bind and lock the tail piece at the front of the back or sole
plate N, and to prevent the possibility of the bolt P becoming loose from any
undue strain or vibration 1 employ a check screw Q which engages with the
head of the bolt P as shown.
The guide socket piece R is secured to the back or sole plate N by a large
headed check screw S, and if desired a washer, situated under the rubber
buffer T which can be easily removed for repairing or cleaning purposes by
springing the said buffer T out of its encased position and unscrewing the check
screw S. The guide socket piece R is also recessed for the reception of the
front tail piece of the back plate N.
My said invention also consists in forming the knob or handle U for operating
the waste pull and plug with a check joint V which allows the said knob to

page_text: fall back and rest on the buffer T, as described in the beforementioned
Specification No. 12707 of 1892, that is to say when in its normal position the
joint V is within the socket piece R and when open the check joint V rests on
the top of the socket piece R as shown in Figure 2. The modification of the
straight rigid rod for turning the valve horizontally to the side of the plug
socket, refers also to the knob or handle which when thrown or allowed to fall
back rests only on the buffer T in its normal position when closed, the object
in both cases is to place it still further out of the way of the user and so cause
no obstruction.
As a modification I may form the knob or bandle U as shown in Figure 7.
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 :-
1st. In waste and overflow apparatus or fittings for lavatory basins and the
like, forming and combining the main discharge and overflow passages with
screwed basin and trap connections integral, substantially as herein before described
and shown in the accompanying drawings.
2nd. In waste and overflow apparatus or fittings for lavatory basins and the
like, the arrangement and construction of the branch or bend C forming the
discharge and overflow passages with an encased flange and projecting ear or
wing all integral, substantially as hereinbefore described and shown in the
accompanying drawings.
