page_text: I, BLANCHE JULIA NICOLE (Married), of Holly Lodge, Friern Barnet, Middle-
sex, do hereby declare the nature of this invention to be as follows:-
In the construction of metal taps for seltzogenes, syphons, and other vessels, it
is usual to employ a cheap metallic alloy as a basis, and to plate the same with
gold or silver, thereby preventing contact between the base metal and the mineral
water, which would result in the contamination of the latter.
In this operation of plating, however, which is done electrolytically, there is a
considerable deposit of the precious metal, not only on the interior of the tap,
where the contact with the mineral water takes place, but also on the outside,
where there is no need for plating, and consequently the taps are unnecessarily
expensive.
According to the present invention, this unnecessary expense is obviated, by
preparing a lining of tin, or other suitable metal, and after plating it inside and
out, casting around it the metal which forms the main body of the tap. In this
way only that portion of the tap which is to be in contact with the water carries
any precious metal, and the outside or remaming portions may be of any con-
venient base metal or alloy.
It is obvious that instead of a plated lining, a lining of pure silver may be
employed, if desired. In any case, an economy of precious metal is effected,
which will materially cheapen the cost of metal syphon and similar taps.

I, BLANCHE JULLA NICOLE (Married), of Holly Lodge, Friern Barnet, Middle-
sex, 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:-

In the accompanying drawing I have shewn my invention applied to a syphon
tap.
Fig. 1 is a sectional elevation of the tap complete, and
Fig. 2, is an elevation of the lining, detached.

shewn in Fig. 2. The linig thus prepared is plated electrolytically, and finally
embedded in a casting of base metal, which forms the body of the tap b.

which will materially cheapen the cost of metal syphon and other taps.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
The herein described improvement in taps for seltzogenes, syphons, and similar
vessels, wherein a lining is employed, embedded in the body of the tap, made of
cheap metal, substantially as above explained, for the purpose set forth.
