PROVISIONAL SPECIFICATION.
Improvements in Taps.
I, DONALD BARNS MORISON of Hartlepool Engine Works Hartlepool in the
County of Durham, Engineer do hereby declare the nature of this invention to be
as follows:-
My invention consists in forming in a tap or cock, an auxiliary passage, suitably
regulated and arranged so that a small portion of the full capacity of the cock or
tap may be discharged through the bye-passage when required. My invention is
specially adapted to such purposes as cylinder drain cocks, steam inlet cocks for
coal or grain whips, or hoists, and the brining cocks of evaporators. In the latter
case for example, a small quantity of brine is required to be discharged continuously,
and the whole quantity completely drained off periodically. The valve on the
bye-passage is regulated to discharge the small quantity, and need not be interfered
with when the full capacity of the cock is required.
Dated this 23rd day of March 1892.

COMPLETE SPECIFICATION.
Improvements in Taps.
I, DONALD BARNS MORISON, of Hartlepool Engine Works, Hartlepool, in the
County of Durham, Engineer 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:—
My invention consists in forming in a tap, cock or the like an auxiliary passage
suitably regulated and arranged so that a small portion of the full capacity of the
tap or cock may be discharged through the bye passage when required.
My invention is specially adapted to such purposes as cylinder drain cocks,
steam inlet cocks for coal or grain whips or hoists and the brining cocks of
evaporators. In the latter case, for example, a small quantity of brine is required
to be discharged continuously and the whole quantity completely drained off
periodically. The valve in the bye passage is regulated to discharge the small
quantity and need not be interfered with when the fully capacity of the cock is
required.
In order that my invention may be fully understood I append two sheets of
explanatory drawings:
Figs. 1 and 2 shew respectively in vertical section and plan partly in section my
invention as applied to an ordinary open bottom two way cock with the auxiliary
or bye passage 1 communicating with the branch of the cock 2 and the open
bottom 3 through the port or opening 6; the amount of fluid to be discharged being
regulated by the bye passage valve 4 and handle 5. This bye passage valve may
be arranged with a gland and stuffing box 7.
In both Figs. 1 and 2 the port in the main plug of the cock is shewn at right
angles to the branch 2, so that there is no communication between branch 2 and
the open bottom 3 except by means of the bye passage 1 and port or opening 6.
It will be seen, therefore, that by regulating the valve 4 any desired small
quantity of fluid may be discharged continuously through the opening 6, and when
it is required to open or close the main plug of the cock no interference with the
bye passage valve is caused thereby.
Such an arrangement, as shewn in Figs. 1 and 2 is specially adapted for the
Prine 821

page_text: brining cocks of evaporators where, in addition to the small quantity of brine to
be discharged continuously through the bye passage the whole capacity of the
cock is required periodically for the discharge of the whole of the water in the
evaporator.
Figs. 3 and 4 shew (partly in section) in elevation and plan my invention as
applied to an ordinary stop valve where I is the bye passage as in Figs. 1 and 2,
communicating with the upper part of the valve chest 2 and the lower part 3
through the opening 6 by means of the regulating valve 4 and handle 5.
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. A tap or cock arranged with a bye passage regulated by means of a valve
substantially as illustrated and described.
2. A stop valve arranged with a bye passage regulated by means of a valve
substantially as illustrated and described.
Dated this 21st day of December 1892.
