COMPLETE SPECIFICATION.
Improvements in and relating to Connections for Water Closets,
Sinks, and other like purposes.
I, THOMAS ROBINSON, of 103, Ramsden Road, Wardle, in the County of Lan-
caster, 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 object of this invention is to provide a water and air tight joint in con-
nection with the outlet orifices of water-closet basins, sinks, and other like
thoroughfares, also a contrivance for ensuring an effective water seal and venti-
lation of the trap during discharges through the trap.
This invention relates particularly to certain improvements of my former inven-
tion being the subject of Letters Patent No. 9564 A.D). 1894 titled "Improved
means for connecting metal pipes to earthenware drain pipes, water closet basius
or traps also to the connection of other metal pipes for similar purposes.
In order that my invention may be perfectly understood I have reference to
the accompanying sheets of drawings in which like letters of reference indicate
like parts through out the figures therein shewn.
Figure 1, is a view in elevation and part section shewing the application of my
invention to watercloset having a S trap outlet.
Figure 2, is an elevation in part section shewing the application of my inven-
tion to water closet basin and known as an underline closet.
Figure 3 is a plan of the outlet pipe or bend constructed or drawn from one
piece of metal.
Figure is an elevation in part section shewing my cap and bend the cap being
provided with an earthenware lining.
Figure is an elevation in part section shewing my cap and bend without earth-
enware lining,
Figure 6 is a sectional drawing shewing a novel arrangement or relative posi-
tions of the airing let orifice to the outlet orifice of water closet basins.
According to my present construction I form at a convenient part of the crown
of the S trap as shewn in Figure 1, an air bend or orifice A¹ the position of
which relatively to the outlet is important as when water is discharged through
the trap in the direction of the arrows, current or suction is created at a' air may
be thus drawn into the air pipe obviating any possibility of the air orifice being
closed, blocked or obstructed by and during the flow of water through the trap
as is now the case with watercloset basins as at present constructed. I also em-
ploy in conjunction with the solid drawn bend a, of lead the terminals of which
are suitably bent or manipulated whilst the tube is passing through the moulding
apparatus, during manufacture, thus by this arrangement the ends may be bent
in any suitable position relatively to each other obviating the use of joints and
effecting economy in construction the cap which is soldered or burnt on to the
bend at 6 or the bend is sleeved through the cap, the end of the bend passes
into the socket recess or shoulder, c, formed at the outlets or terminal parts of the

page_text: water closet basins, d, and e, see Figures 1 and 2. As shewn in Figure 1, the
shoulder extends and passes around the outside of the shoulder piece c', within
which cap is provided a circular or cylindrical piece of earthenware f, between
which and the outside of the shoulder piece is formed a space, a space c³, is
also formed between the inside of the said shoulder piece c', and the end of the
lead pipe or bend a. In which spaces, and c³, I provide cement for making a
secure and effective joint.
I also employ in connection with the cap b, any convenient number of suitably
bent metal clips, or pieces provided with screw threaded ends g', and nuts g
which screw threaded ends pass through a circular ring or pieces h, and ',
placed around the neck i, of the shoulder piece el, by which means the cap b, may
be drawn in close contact with the outlet of the water closet basin thus further
securing the lead bend thereto.
Figure 2 shews the bend a, provided with a cap and earthenware or metal
piece k, which forms a spigot end on the said lead bend and fits within the re-
cess, of the outlet of the water closet basin, similar to the outlet as shewn in
Figure 1, the space, between the earthenware or metal piece k, and the inside
piece c, is filled in with cement in order to form a secure and effective joint, and
if desired the clips g, and ring h, as shewn in Figure 1, may be employed in this
arrangement or modification of my said invention. The said piece k, is preferably
made of metal if it is desired to employ the same in connection with a metal
terminal.
Figure 5, represents modification of cap and bend as shewn in Figure 4, which
cap is wholly constructed of metal not being provided with the earthenware lining
as shewn in Figure 1, which metal cap and hend may be applied to the outlet of
a water closet basin of the form s shewn in Figures 1 and 2, which form of out-
les in combination with the cap and bend as shewn in Figures 1 and 5 also in
combination with the spigot end as shewn in Figure 2, and the combination of
the air inlet orifice relatively to the outlet orifice constitute this my invention.
The arrangement or contrivance shown in Figure 6, is provided to secure a
free access of air at the air inlet orifice during the flow or discharge of waste
water through the trap. The air inlet orifice being shewn at the part as illus-
trated in the drawings i.e. immediately over the trap in the earthenware basin
ensures the supply of a volume of air exercising a pressure on the water in the
trap which is important, as a body of water therein may be maintained in a state
of quiesence whilst an outflow or discharge of water is passing through the trap,
consequently an effective water seal may be maintained between the chambers/
and m, of the basin trap, as the water passing through chamber m will flow past
the air inlet orifice a¹ instead of impinging on or being directed against the said
opening which would be the case if the air inlet orifice were placed further from
the basin, i.e. near or towards or over the outlet, according to the present con-
struction.
This arrangement adds strength or rigidity to the basin as it will be observed
that the air inlet orifice and junction is placed near to the side of or immediately
behind the basin, and which arrangement admits application to a S trap
basin as shewn in Figures 1 and 6, or a P trap basin, both of which forms are
well known.
The employment of the solid drawn bend enables me to dispense with the use
or employment of two separate bends i.e. the joining or brazing of a bend on the
said outlet pipe or bend when an obstruction occurs preventing the outlet of the
bend ie the end attached to the outlet of the closet basin, according to this my
arrangement the bends i.e. at each end are formed in one piece being drawn and
so formed in their manufacture, thus by this arrangement of a solid drawn bend
economy in construction is effected and escape of gas or water existing and pass-
ing through such a bend is obviously obviated.
The use and application of a metal spigot piece k, end before referred to and

page_text: shewn in Figure 2, enables me to use or attach the same to a metal terminal which
may be a metal pipe of a drain sink, watercloset or other analogous piece.
It will be observed that the form of the outlets in the water closet basins and
the caps or arrangement shewn in Figures 1, 2, 4, and 5, of the drawings herein
are respectively the forms of caps and arrangements as shewn in Figures 2, 3, 4,
and 5, respectively of my prior Specification No. 9564 A.D. 1894 and above
referred to.
Having now particularly ascertained and described the nature of my said
invention and in what manner the said is to be performed I declare that what
I claim is:-
1 In combination the form of the outlet having an outer and an inner shoulder
or flanges and c, the air inlet al, a cap b, and solid drawn bend a, which cap
may have or have not a circular earthenware piece or lining the slips g, and the
ring h, as shewn in Figure 1, 4 and 5 substantially as and for the purposes herein
fully set forth and described in the drawings hereunto annexed.
2. In combination the cap earthenware or metal piece f and the solid drawn
metal bend, with the form of the outlet having shoulder parts or flanges Cor
(as shown in Figure 2, with or without metal clips and ring and h, substan-
tially as and for the purposes herein fully set forth and described in the drawings
hereunto annexed.
3. The combination cap b, with or without earthenware lining f solid drawn
benda, clips g and the ring h, substantially as and for the purposes herein fully
