Improvements in Taps for Measuring and Supplying Liquids.
I, JAMES ALFRED Mossop of 24 The Park, Gilda Brook, Eccles, near Manchester
in the County of Lancashire, 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 ascertained in and by the following statement :-
The object of my invention is to construct a tap for measuring and supplying
liquids in exact quantities, such measuring being effected automatically.
In the accompanying drawings Fig. 1 is a side elevation. Fig. 2 a longitudinal
section. Fig. 3 a plan looking at the top, shewing one arrangement of my improve-
ments. Fig. 4 is a side elevation and Fig. 5 a longitudinal section shewing a
modification of the same in form. Fig. 6 is a part longitudinal section, and Fig. 7 a
transverse sectional plan shewing application of vent to such improvements.
At Figs. 1, 2 and 3 the socket or case A is provided to receive the hollow taper
plug B, which is fitted in the socket A in the manner of an ordinary stop cock plug
as shewn.
The hollow space or chamber C in the plug B is made of such a size as to contain
the liquid to be measured and supplied, and into this hollow space or chamber C
openings D and E are made; through the former the liquid is passed into the hollow
space C, and through the latter the liquid passes from the hollow space or chamber C.
In order to fill the hollow space or chamber C in the first instance, the plug B is
turned round so as to bring the hole opposite the inlet passage F, and in so doing
the opening E is turned away from the outlet passage G.
When it is intended to discharge the liquid from the hollow space or chamber C, the
plug B is turned into position shewn in drawings, closing thereby the inlet passage F
and opening the outlet G, thus supplying or giving off the measured quantity. In
order to assist the outward flow of the measured quantity, I cut a small vent H in the
side of the socket A, this comes opposite the inlet hole D when the outlet E is open,
as shewn at Figs. 6 and 7.
At Figs. 4 and 5 I modify the shape of the outer socket or case J, making the
enlarged part J into the measuring chamber, the plug K being reduced at Land
fitting in the socket J only at M and N. The openings P and R in the plug K
performing the same functions as the openings D and E in plug B.
The above described tap is applied in the usual way, and may be employed instead
of the ordinary tap where measuring of liquid is required.
It is to be understood that I reserve to myself the right to vary the form,
proportion, dimensions and materials employed in carrying out the above invention,
which may be variously modified without departing from the distinctive feature
thereof.
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 :-
1st. A tap, having a hollow space or chamber for receiving and measuring liquids
in exact quantities, substantially as herein set forth and illustrated in the accompanying
drawings.
2nd. The arrangement, construction and combination of the various parts forming
the tap for measuring and supplying liquids, substantially as herein set forth.
