PROVISIONAL SPECIFICATION
Improvements in or relating to Stone-ware, Glass, and other Fictile
Ware in which Taps are Fitted.
I, PAUL YEWDALL CLIFF of 2 Kenilworth Road, Seacombe in the County of
Chester, Commercial Traveller, do hereby declare the nature of this invention to be
as follows:-
In stone ware receivers and other chemical apparatus made of fictile ware
required for acids, the taps have to be made of glass or earthenware and these taps
are usually ground into the nozzles and fixed with a non corrodible cement. They
are however very apt to leak and the taps to get knocked loose and my invention is
designed to avoid this.
I form the taps with a flange and a screw thread and I form an ordinary screw
thread in the nozzle of the pan jar copper receiver or other like article. The tap
is then anointed with asbestos paint or supplied with an asbestos washer or both and
is screwed up tight in place.

COMPLETE SPECIFICATION.
Improvements in or relating to Stone-ware, Glass, and other Fictile
Ware in which Taps are Fitted.
I, PAUL YEWDALL CLIFF, of 2 Kenilworth Road, Seacombe in the County of
Chester, Commercial Traveller, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :--
In stone ware receivers and other chemical apparatus made of fictile ware
required for acids, the taps have been made of glass or earthenware. These taps
have been hitherto usually ground into the nozzles of the vessels. The nozzles
however are very apt to leak, and the taps to work loose through repeated use, or
even to fall out.
My invention is designed to avoid this leakage from acid receivers, and also from
beer and spirit vessels, etcetera.
In carrying my invention into effect, I form the taps with a flange and a screw,
and I form an ordinary screw thread in the nozzle of the pan, jar, copper, receiver,
or other like article. The tap is then supplied with an asbestos or other suitable
washer.
The invention will be best understood by reference to the accompanying drawings,
in which,
Figure 1 represents an acid vessel partly in section with the tap just entering
the nozzle ;
Figure 2 a mineral water vessel with the tap secured to the under part; and
Figures 3 and 4 show spirit or beer kegs or jars with taps entering the nozzle and
screwed therein respectively.
Referring to Figure 1, A is the tap formed with a flange a and a screwed
portion a'. The vessel B has also a thread formed in the nozzle b to receive the
screwed portion a' of the tap. The latter is first coated with asbestos paint or
paste, or supplied with an asbestos washer, or it may be both coated and supplied
with a washer. It is then screwed up tight in the nozzle of the vessel.
ID 1

page_text: The invention, when applied to mineral water vessels, and spirit kegs and beer
and spirit jars, (Figures 2 to 4 inclusive) is substantially similar to the foregoing.
A rubber, asbestos, or other suitable washer is used, and the coating with asbestos
paint is omitted if desired. The invention entirely dispenses with the old plan of
using corks and paper wrapping and grinding in of the taps.
Taps secured in this manner will stand any pressure, acid or otherwise, and there
is no danger of the said taps falling out or of leakage, and the grinding will be
entirely dispensed with. Instead of screwing the taps into the nozzles, they may be
screwed on the outside of them if desired.
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 :-
.
1. The improvement in stone ware, glass and other fictile ware in which taps are
fitted, substantially as set forth, whereby the grinding, corking or packing of the
taps in the nozzles is dispensed with, and leakage avoided.
2. The combination of a pan, receiver or the like, of stone, glass or other fictile
ware for acids, beer, etcetera, having a nozzle formed with a screw thread, with a tap
having a flange and a screwed portion, the latter adapted to screw into the nozzle,
and means for making a tight joint between the said nozzle and tap, substantially
as described.
