PROVISIONAL SPECIFICATION.
A Combined Thermometer and Gauge for Indicating the Temperature
and Quantity of Liquor Withdrawn from Tanks, Oisterns, and
the like.
I, JOHN EDWARd Williams, of 193 Gipsy Road, West Norwood, London S.E.,
Engineer, do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to provide and fit tanks, cisterns, and the like,
with a combined apparatus, consisting of a thermometer and gauge, for simultaneously
indicating the temperature and quantity, of liquor withdrawn from such vessels, for
use in bakeries, breweries, and other analogous places.
I make an opening in the tank or other vessel (herein after for the sake of
brevity called a tauk) and fit the same with a suitable frame and glass, the joint
being made fluid-tight. Behind the glass I fit a sliding scale board in a fraine
attached to the tank, capable of being raised and lowered by means of a toothed
rack attached to the scale board, and a pinion in gear therewith. The axle of
the pinion passes through a stuffing box to the outside of the tank; the outer end
being fitted with a hand wheel for turning the pinion. The therinometer is
(preferably) of a large size and is fixed to the scale board upon which enamelled
scales are formed, consisting of a thermometer scale of degrees to indicate tempera-
ture, and a scale to indicate gallons of liquid.
•
.
A door is fitted in front of the apparatus for protecting the glass panel from
injury.
The scale can be raised or lowered, as required, to the level of the liquid
contained in the tank, and, when tempered, any required number of gallons may be
run off.

COMPLETE SPECIFICATION.
A Combined Thermometer and Gauge for Indicating the Temperature
and Quantity of Liquor Withdrawn from Tanks, Cisterns, and
the like.
I, JOHN EDWARD WILLIAMS, of 198 Gipsy Road, West Norwood, London 8.E.,
Engineer, do hereby declare the nature of my said 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 provido and fit tanks, cisterns, and the like (all
herein after for the sake of brevity called tanks) with a combined apparatus for
enabling the operator withdrawing liquids therefrom, to ascertain the quantity and
temperature of the same; such apparatus being specially (but not exclusively)
applicable for use in bakeries, breweries, and other analogous places.
I make an opening in the tank, and fit the same with a suitable frame and glass,
through which the height of the liquid and the scale and thermometer may be seen.
TAJ1

page_text: To this frame I fit a sliding scale board and thermometer, the thermometer being
attached to the scale board. The scale board is fitted with a rack, in gear with a
pinion, or with other well known mechanical appliances, for raising and lowering
the same by hand, so that the operator may be enabled to set the zero mark of the
scale to the liquid level, previously to withdrawing liquid from the tank, and thus
ascertain with precision, by means of the scale, when he has withdrawn the required
quantity of liquid.
In some cases I dispense with the thermometer, and fit the scale board only to
the tank.
The scale may be made of metal, wood, or any other suitable material, or com-
bination of materials; and, when made of wood or other material of low specific
gravity, I sometimes make the same of sufficient bulk to enable it to float with the
zero mark at the liquid level.
When the scale and thermometer, or the scale only, are constructed and balanced
so as to float in the liquid with the zero mark in a horizontal plane, corresponding
to or identical with the level of the water or other liquid in the tank, a tap with a
borizontal plug may be used for drawing off, and an eccentric, or stopping lever, or
other suitable contrivance, may be fitterl to the inner end of the plug, so that tho
scale may be bold in a stationary position while the tap is open, and released when
the tap is closed; or the scale may be temporarily held in a stationary position by
means of a wire or cord attached thereto, as herein after described.
And in order that my said invention may be particularly described and ascertained,
reference is hereby mado to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is a horizontal section of the apparatus, showing one method of fitting the
Bame to a tank, and
Fig. 2 is an elevation of the combined scale and thermometer.
a is a portion of a tank. is an opening or window formed in the tank, and
fitted with a frame c. dis a plate of glass fitted behind the opening, and rendered
watertight by rubber or other packing ee. is the thermometer attached to the
scale board g, and sliding up and down therewith. h is a toothed rack fitted to the
back of the scale board. is a pinion loose on the stud 1, and m is another pinion
fast on the spindle n. The spindle is fitted in a stuffing box o, and is actuated by
a hand wheel p, as shown: By turning the hand wheel p in either direction, as
required, the pinion m turns the pinion, and the latter acts upon the rack h, so as
to raise or lower the scale board g and thermometer f.
It is obvious that any other well known mechanical methods of raising and
lowering the scale-board may be utilised; thus one pinion only may be fitted to
operate the rack: or a cranked lever may be fitted to the spindle a connected with
the scale board by a link or the scale board may be raised and lowered by means
of a wire passing through a stuffing box (if necessary,) or by a cord; or other
equivalent devices may be used for the same purpose..
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 :-
:
1. In an apparatus for enabling an operator to withdraw a definite quantity of
liquid from a tank: the combination of a glazed aperture or window, and a scale-
board fitted.so as to be capable of being raised, lowered, and adjusted, substantially
as herein before described aud illustrated by the drawings.
2. In an apparatus as aforesaid, the combination of a glazed aperture or window;
a scale-board fitted so as to be capable of being raised, lowered, and adjusted, and
a.thermometer attached to such scale board, substantially as and for the purposes
herein before described and illustrated by the.drawings.
:
3. The general construction, arrangement, and combination of the several and

respective parts, together forming my invention of a combined thermometer and
gauge for indicating the temperature and quantity of liquor withdrawn from tanks,.
cisterns, and the like, substantially as herein before described and illustrated by the
drawings.
