COMPLETE SPECIFICATION.
Improvements in Sink Supports and Fittings.
We, J. DUCKETT & SON, LIMITED, of Sanitary Ware Works, Burnley, in the
County of Lancaster, JAMES DUCKETT of Woodleigh, Burnley aforesaid, Sanitary
Ware Manufacturer, and CORNELIUS MERCER, 30, Hollingreave Road, Burnley
aforesaid, Joiner, 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 first part of our invention has reference to sink waste pipes, sink grates, and
traps, and consists of an improved arrangement and combination of the same.
In the sink an undercut opening or recess is formed, into which we fix a metal
grating with a socket, and with one or more projections at the bottom to enter the
undercutting in sink, all formed in one piece of metal. This grate is placed in the
said undercut opening, and after being well bedded in cement or other suitable
material, the grate becomes firmly attached to the sink. The socket on the
underside of the grate is tapped to receive a short length of pipe, preferably about
six inches in length, which is screwed to fit into it, or the two parts may be
detachably connected with a bayonet joint or otherwise. This pipe may be readily
removed when required, so that access may be had to the waste pipe for cleansing
purposes.
The said short length of pipe is designed to conduct the waste water from the
sink into a siphon trap with a wide mouth, and so placed that the sink water will
fall direct into it.
The short length of pipe is preferably made of metal, while the siphon trap and
the pipes, leading from it to the dishbrick in the yard, may be of earthenware, and
the joints of the trap and wastepipes are rendered watertight by the well known
"Stanford" or other suitable watertight joint. This mode of jointing earthenware
pipes facilitates the removal and refixing of the parts when cleansing.
The lower end of the outlet pipe may be hooped with iron to prevent the ware
being broken.
In some instances, the siphon trap may be dispensed with, and the short metal
pipe may lead direct into the sink waste, the top end of the latter having a funnel
shaped mouth.
Referring to the annexed drawings, Fig. C. is a sectional elevation of sink, sink
grating, and short pipe connection, constructed and arranged in accordance with
our invention.
1 is the sink formed with undercut recesses 12 and 13, into which is fixed the
grating 6 with a socket or extension 14, which may be dovetailed to enter slightly
into the recess. The socket 14 is tapped to receive a short length of pipe 2, which
is screwed to fit the same. As will be seen in Fig. A, this short length of pipe 2
conducts the sink waste into the trap 3, which is formed with an expanded mouth,
so that pipe 2 may be readily removed. The waste pipes are preferably formed
of earthenware jointed together by the well known "Stanford "or other suitable
watertight joint. 5 is the house or scullery floor. In Fig. B the trap 3 is dispensed
with, and the upper connecting pipe 4 is formed funnel shaped at the top for the
purpose before mentioned.

page_text: The second part of our invention relates to certain improvements in pillars for
supporting sinks. Hitherto sink pillars when made in one piece of ware have been
ade rectangular, round, oval, or of a somewhat similar form in horizontal section.
Now, as waste pipes are often placed near one corner of the sink, the above pillars
bave frequently to be cut in order to make room for such pipes.
In order to remove the above objection, and to considerably reduce the cost
manufacture, we make our pillars of a L shape preferably as shewn on annexed
diagram, Fig. D, which clearly shews in what manner we make one block into two
pillars at one operation each pillar being prepared to receive a stud, to which a
door may be hinged.
We make the pillars of glazed or other suitable ware and preferably with a press
such as is used for making sanitary pipes, but they may be made in plaster moulds, if
desired. When made with a press, they are, in the first instance made hollow and
rectangular in one piece of ware with two vertical cuts in each block, so that after
the block is burnt, it can be readily divided so as to form two separate pillars from
one piece. By thus making two pillars out of one block, the cost of manufacture
of each single pillar is greatly reduced, and the efficiency is increased by allowing
more room for kitchen utensils etc. under the sink.
We form holes in the pillars to receive bolts for fastening vertical wood rails or
studs, to which a single or folding door may be hinged to enclose the said utensils.
These studs may be dispensed with, and bands and gudgeons used instead, the latter
being bolted to the ware.
Our mode of making these pillars with preparations in them for hinging doors
dispenses with the plugging of comparatively loose brick pillars for fixing faceboards
thereto. It also dispenses with the usual plastering of the sides of the pillars,
which is liable soon to get damaged and become unsightly. Hinged doors as
previously fixed in such positions have been more costly, and yet not so firmly nor
permanently secured.
Fig. D of the accompanying drawings is a plan view of our improved sink pillar
as it is manufactured by a press for making sanitary pipes, and also a plan view or
cross section of a single door secured to one half of the said pillar is the manner
hereinafter described.
The pillar as it is expressed from such sanitary pipe press first takes the form of
a hollow rectangular piece of ware 8, 8 shewn partly in dotted lines, and partly in
horizontal section in the said fig. Two deep.vertical cuts at the points 11 are
made in the block, so that after the block is burnt, it can be easily divided so as to
form two pillars. For the purpose of clearly understanding our invention, we will
assume, therefor that the portion 8 shewn in dotted lines, has been severed and cut
away, leaving the other half remaining, which is shewn in horizontal section. That
portion taken away will serve as a pillar at the opposite end of the sink or
otherwise.
We form holes iu the pillars to receive bolts 9 for fastening vertical wood studs
or rails, to which may be readily hinged a single or folding door 10 for the inclosure
of kitchen utensils. The sink waste pipe is shewn at 6 in dotted lines.
These pillars may be suitably ornamented or fluted as shewn."
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved arrangement and combination of sink grate 6 cast or formed
with undersocket 14, to receive detachable short pipe connection 2, leading into
open mouthed trap 3 (or pipe 4) and pipes 4 substantially as described and
illustrated.
2. The improved combination of sink grate 6 provided with undersocket 14 to
receive detachable pipe 2, which enters into trap 3 or pipe 4 substantially in the
mauner described and set forth.

page_text: 3. The manufacture and use of supports for sinks, substantially in the manner
described and illustrated in Fig. D.
