An improved Bush for the rap moles of Darthenware of GraDS
Filters and in Means of Fixing the same in said Holes.
We PERCIVAL PHILIP KIPPING of 58 Southwark Street, London, Manager of
Filter Department (Messieurs Daniel Judson and Son Limited) and FREDERICK
HENRY JUDSON of 77 Southwark Street, London, Manufacturer do hereby declare
the nature of our said invention to be as follows:-
The object of this invention is to manufacture a bush for the tap holes of Earthen-
ware or Glass Filters by casting or otherwise with ribs, fillets or grooves upon the
exterior which is many sided, preferably four-sided or square, and threaded on the
interior for the reception of the tap stump, it is also made with a flange flush with one
end.
The bush is fitted into the tap hole by Portland or other cement which when set
firmly fixes the bush therein and from its form is prevented turning when the tap is
screwed home whereby a perfectly watertight joint is secured.
The bush is preferably of Brass, the ontire surface of which is tinned and when
cemented in is allowed to project slightly so that when the tap is screwed home the
pressure is exerted against the bush only.
A washer of leather or other material is fitted between the bush and the shoulder
flange of the tap which flange may be formed with a rim to hide the leather, the
thickness of the leather or other washer as usual determines the vertical position or
"set" of the tap.

page_text: WO, PERCIVAL PHILIP KIPPING of 58 Southwark Street, London, Manager of
Filter Department (Messieurs Daniel Judson and Son Limited) and FREDERICK
HENRY JUDSON of 77 Southwark Street, London, Manufacturer 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 :—
Tho object of this invention is to manufacture a bush for the tap holes of Earthen-
ware or Glass filters, by casting or otherwise, with ribs, fillets or grooves upon the
exterior which is many sided, preferably four-sided or square, for the reception of
the tap stump, it is also made with a flange flush with one end.
The bush is fitted into the tap hole by Portland or other cement which when set 1
firmly fixes the bush theroin and from its form is prevented turning when the tap is
screwed home whereby a perfectly watertight joint is secured.
The bush is preferably of brass, the entire surface of which is tinned and when
cemented in the filter is allowed to project slightly so that when the tap is screwed
home the pressure is exerted against the bush only or against a packing, say, of
cork, leather, rubber, or other material.
A washer of leather or other material is fitted between the bush and the shoulder
flango of the tap, which flange may be formed with a rim to hide the leather;
the thickness of the leather or other washer as usual determines the vertical position
or sott" of the tap.
"
Our invention will be understood by reference to the annexed drawings. Figures 1,
2, and 3 represent a square bush A with ribs, fillets, or grooves B upon its exterior
and when cemented in the tap hole is allowed to project slightly so that when the tap
is screwed home tho pressure is exerted against the bush only.
In Figures 4, 5, and 6 we show the bush A of hexagon form with ribs, fillets, or
grooves BB on the exterior similar to the previous Figures; and in Figure 7 the
Bush is provided with a shoulder or broad flange C for a leather washer E on the
tap to abut against when the tap D is screwed home in the bush or socket A cemented
in the tap hole of the filter G as at Figure 8.
We prefer that the flange be formed with a rim F to hide the leather or other
washer E as shown at Figure 9. The thickness of the leather or other washer
as usual determines the vertical position or "sett" of the tap D.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we declare that what we claim is :-
The improved bush A shown on the annexed drawings provided with projections or
ribs B on the outer surface and with or without the flange C, and its application or
fixation to earthenware or glass filters by cement as and for the purpose described.
