PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Drawing Off Liquids.
1, JOSEPH JAMES CLARK 35 De Burgh Street Canton Cardiff do heroby declare
the nature of this invention to be as follows:-
My invention relates to the construction and use of an apparatus suitable for
drawing off oils, spirits, wines and other liquids through one common tap, from
tanks, cisterns or other reservoirs, so that it is possible to draw off at will the
liquid from any level, and consists chiefly of a vertical tight tube or pipe of any
suitable size fitted with valves at intervals of one foot, or more or less apart, such
valves are arranged. on one common vertical valve spindle, and are fitted in, such a
manner that only one valve is open at the same time.
The valves are actuated by means of any convenient method of turning the
common spindle, either by crown wheel and chain, geared wheel, handle or other
suitable means.
At the bottom of such stand pipe or tube a common tap of any suitable construction
is fixed into the pipe and through the side of the tank cistern or other reservoir
into the open.
The stand pipe is kept covered and an air hole is provided for destroying the
vacuum.
Said stand pipe and valves is made up in sections of any desired length and any
desired number of valves, to suit any tank cistern or reservoir of any depth, and any
number of valves can be fitted together at will.
The object of my invention being to allow the bulk of the liquid in the tank
cistern or other reservoir to settle, and to be able to draw off from any of the
top layers of same through any of the valves down the pipe and out at the
common tap.
When one of the valves is open the liquid only above the valve will flow down the
pipe and be drawn off at the tap, and all the liquid below is kept in stock longer
until it is found to have cleared, when another and lower valve can be opened and
a lower layer of the liquid be drawn off at will.
My valves and seats can be made similar to that of any common plug tap, and
I so arrange it, that at any time any length or lengths with the valves attached
can be unscrewed and the stand pipe shortened without interfering with the working
of the portion left, and vice versa the pipe can be lengthened in the same manner by
screwing on any additional lengths with the valves attached.
This arrangement is for facilitating the repairing or adapting the stand pipe to
any sized tank cistern or other reservoir.
The pipe, valves and spindles can be made of any desired material but I prefer
metal, brass, irou, tin, copper or other metal.

page_text: I JOSEPH JAMES CLARK, 68 Hamilton Street (late 35 De Burgh Street) Canton
Cardiff Accountant 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 relates to the construction and use of an apparatus. for drawing.
off oils, spirits, wines and other liquids through'one common tap, from tanks cisterns
or other reservoirs, so that it is possible to draw off at will the liquid from any level
and consists chiefly of a vertical tight tube or pipe of any suitable size fitted with
valves int intervals of one foot or more or less apart; such valves are arranged on
one common spindle, andiare fitted in such manner that only one valve is open at
same time;:.and in order that the same may be more readily understood
I have caused to be annexed to this Specification one sheet of drawings: the
different figures and letters of reférence marked upon which will be hereafter
referred to..
the

Figures 1 and 2 show the manner in which the apparatus is made and consists
of a series of vertical tubes " 39 46
"and valve cases "b" "b" fixed together
either by bolts, screwed or any similar: well known-mode of fixing, so that
when sofixed. the tubes or pipes"a" "a" and the valvo casesebb form
a continuous tube or pipe made liquid tight, and are fixed inside a tank cistern orr
other reservoir in a vertical position near the side thereof..
In each of the valve casings "6" "6" I fix an ordinary shaped hollow" plug
valve ee with top bridge and boss" d" "d" through which the continuous
centralispindlee passes the entire length and to which each plug valve"""c"
is fixed either by keys and ways, cotters or collar and set screws, in Fig. 1:I show
collar and set screws as a fixing such fixing being to hold the valves""""down
in their seats and to the spindle...
I fix the bottom of such spindle "e" to the bottom length of pipe in any suitable
manner 80 as to keep it central and hold it in its place and to allow it to
revolve at will, in Fig 1 show it screwed to a seating with set sorew and
shouldera!!! e."
The centralspindle is made to revolve with its valve plugs by any suitable
arrangement, of crown wheel, tooth wheel pulley and chains or handle or any other
well known mode of causing same to revolve round its axis-
In Figa Ishowione method of causing such spindles to revolve vis. by a crown
wheel "" which fits into the top of the spindle having a round boss working in the.
collar," fixed to the top of the top length of pipe, ffix a cord or chain"""""
round such crown wheel and pass the two ends over small pulloys."""the ends.
of which hang down the outside of the tank oistern or other reservoir: """" and
terminate in two weiglited handles """"to keep the cord or uhains tight, one
Buoh handle has an indicator or pointer
attached..
The valve cases """" have an opening or way "m" through the side.and
a corresponding way through the plug" ""-those openings, or ways in the
valve cases are set at various angles round the axis of motion and the openings in
the valve pligstare all vertical over each other, so that when the openings of one
valve and valve case are together, the other openings in all the other valves and 4
cases are closed or blind-or the openings in the valve cases may be all in the
same vertical line and the openings in the hollow plug valves may be set at various
angles, which arrangement operates the same as the one abore indicated.
"and
All the valves are actuated or made to revolve by one common, spindle "e
it follows that by a slight movement of the spindle the upper valve that was open cant

the length of the pipe to the lowest valve.
"
At the lowest extremity of the pipe I fix a branch pipe and common tap "n
which is attached to and passes through the side of the tank cistern or other reservoir
into the open, and an air hole "p" is made in the top of the pipe.

The pipes
are made up in sections of any length, and any desired
number of valve cases to suit different requirements and arranged so that any length
or lengths and valves can be removed without interfering with the working of the
portion below, and similarly any number of lengths aud valves cau be added
at will.
The mode of working is as follows, When the handle with the pointer is placed
at the indicator painted outside the tank, cistern or reservoir as "off" all the
valves are closed and no liquid can be drawn off when the handle or pointer is
pulled down to No. 1 on the indicator as shown in Fig. 2 then the top valve is open
and all the liquid in the tank, cistern or reservoir above this top valve may be
allowed to flow down the pipe and through the outer tap "n" and all the liquid
below is kept in stock longer until it has settled or cleared when the handle
or pointer can be pulled down to No. 2 on the indicator, then the top valve is closed
and the valve next 'below is open when the next layer of liquid can be drawn off
through the outer tap and so on to the bottom valve.
The pipes and valves can be made of any desired material but I prefer metal,
brass, iron, tin, copper or other metal.
The object of my invention being to allow the liquid in the tank cistern or reservoir
to settle, and to be able without disturbing the liquid to draw off from any of the
top or other layers of same through one common tap.
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. Apparatus for drawing off fluids from various heights through one common
outside tap substantially as herein described and illustrated by drawings.
2. A combination and arrangement of ports and passages and valves in such
apparatus for the opening of one port at a time whilst all the others are closed, for
the flow of liquid through only one such port or opening at the same time in such
manner that the liquid in bulk is not disturbed by the working of the apparatus
substantially as described and shown.
