Improvements in Liquid Gauges.
I, CLAUDE YOUNG PAYNE, of Jhansi, in the North Western Provinces of
India, Mechanic, do hereby declare the nature of this invention-to be as follows :—
My invention relates to gauges for indicating the quantity, depth or weight of
liquid in a tank and to that class of such gauges adapted to be operated by a float.
According to my invention the float is suspended' from a cord wound one or more
times around a drum and a spring is provided, for moving, the latter in a reverse
direction to that in which it is moved by the float, so that as the float rises or falls
the drum will be correspondingly rotated. The float itself preferably moves in a
tube to which the liquid has free ingress at the lower end, the upper end of the
said, tube, being open, to, the atmosphere so as to allow the,free upward and downward
movement of the float with the liquid.
The movement of the drum is utilized for operating suitable counting mechanism
and in practice I find it advantageous to employ counting mechanism having a dial
somewhat resembling the face of a clock, that is to, say, a dial having two hands or
pointers working on a common axis, one of the said hands, say, the longer being
employed for indicating, say, gallons, in units up to a hundred' and the shorter
gallons in hundreds up to a thousand. I also preferably arrange in conjunction
with the dial a sector or disc adapted to shew one of a series of figures through an
opening in the dial for indicating thousands.
It is to be understood that the dial instead of or in addition to indicating, gallons
may be marked to indicate depth or weight.
My improved apparatus is especially applicable for use upon the water tanks or
tenders, of locomotives, and to tanks for storing or transporting, oil or other liquids.

Improvements, in; Liquid Gauges,
I, CLAUDE YOUNG- PAYNE, of Jhansi, in the North Western Provinces of
India, Mechanic, 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 gauges for indicating the quantity, depth or weight of
liquid in a tank and to that class of such gauges adapted to be operated by a float.
According to my invention the float is suspended from a cord or chain wound one
or more times around a drum and a spring is provided for moving the latter in a
reverse, direction to that in which it is moved by the float, so that as the float rises
or falls, the drum, will be correspondingly rotated. The float itself preferably
moves in a tube, to which the liquid has free ingress at the lower end, the upper
end of the said tube, being open to the atmosphere so as to allow the free upward
and downward movement of the float with the liquid.
The movement of the drum is utilized for, operating suitable counting mechanism
and in practice I find it advantageous to employ counting mechanism having a dial
somewhat resembling the face of a clock, that is to say, a dial having two hands or
pointers working on a common axis, one of the said hands, say, the longer being

ganons in uvureus up to a thousa
I also preferably arrange in o
the dial a sector or disc adapted to shew one of a series of figures through an
opening in the dial for indicating thousands.
It is to be understood that the dial instead of or in addition to indicating gallons
may be marked to indicate depth or weight.
My improved apparatus is especially applicable for use upon the water tanks or
tenders of locomotives, and to tanks for storing or transporting oil or other liquids.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which :-
Figure 1 is a front elevation partly in section of the upper part of a liquid gauge
constructed according to my invention and arranged to indicate the quantity in
gallons of a liquid contained in a vessel.
Figure 2 is a transverse section of the same.
Figure 3 is a front elevation of the wheels which convey motion to the long
hand, and,
Figure 4 is a similar view of the wheels which actuate the short hand and the
sector.
Figures 5 and 6 are similar views to Figures 1 and 2 but illustrating the indicating
mechanism adapted to indicate the depth and the weight as well as the quantity in
gallons of a liquid.
Figures 7, 8 and 9 are front elevations of the different sets of wheels for
respectively actuating the three hands.
Figures 10 and 11 are a front elevation and a transverse section respectively
illustrating a modified arrangement of indicating mechanism for indicating the
quantity in gallons, the depth and the weight of a liquid.
a, Figures 1 and 5, is the float; b Figures 1, 2, 5 and 6 is the chain by
which the float is suspended; and c is the drum around which the chain is wound
the said drum being fixed upon a spindle d revolving in a frame e and case f
the weight of the float a as it falls when the vessel is emptying thus causing the
drum to rotate in one direction and at the same time to wind up the spring which
then serves to move the drum in the reverse direction as the float rises when the
vessel is filling; h is the upper part of the tube in which the float moves, and
which prevents the float from oscillating, the liquid having free ingress to the lower
end of the said tube, the upper end of which is open to the atmosphere; i is the
dial of the counting mechanism having two hands or pointers j, k in the arrange-
ment illustrated by Figures 1 to 4, which is more especially adapted for indicating the
quantity of water in a locomotive tender or water tank; the longer hand ; being
employed for indicating gallons in units up to a hundred and the shorter hand k in
hundreds up to a thousand. The arbor of the hand j carries a pinion m having
eight teeth in gear with a wheel n on the drum spindle d and having 48 teeth
so that for each revolution of the drum c, (which for example turns 3 times
for the whole depth of the tender or tank) the hand j moves six times round the
dial. The hand k is carried by a sleeve o working loose upon the arbor 7 and
having fixed thereto a pinion p having ten teeth with which engages a wheel y
having six teeth and fixed on the drum spindle d so that when the long hand j has
.moved once round the dial the small hand k will move from 0 to 1 to indicate one
hundred gallons and so on up to a thousand gallons; r is the sector for indicating
the thousands, such sector being pivotted at & and operated by a fingert on the
pinion p engaging with teeth at the lower end of the sector so that when the small
hand has moved once round the dial the said sector will indicate 1 through the
hole u in the dial, and when the hand k has moved twice round the dial the sector
will indicate 2.
The counting mechanism illustrated in Figures 5 to 9 is suitable for an oil
indicator for a vessel of 400 gallons capacity and 4 feet deep, the weight of the
contents being 4,000 lbs. It has a wheel v on the drum spindle d gearing with a
similar sized wheel w on the arbor of the long hand; so that the latter moves
once round the dial i and indicates 100 gallons for each revolution of the drum c.

page_text: On the drum spindle d is also fixed a wheel & having 60 teeth and gearing with
a pinion y having 6 teeth and fixed on the' arbor z of a hand or pointer a¹ moving
around a graduated circle 6' and indicating 100 lbs. at each complete turu. On the
drum spindle d is also fixed a pinion of having 12 teeth, engaging with a wheel d
having 48 teeth, mounted on the sleeve o of the hand The circle over which the
hand moves is graduated to indicate up to 48 inches and 4,000 lbs. On the face
of the wheel d₁ are four teeth or studs e¹ which engage with the teeth of the
sector marked with figures from 0 to 4 which are thereby successively brought
to view through the hole u in the dial and thus indicate the number of hundreds of
gallons taken out of the vessel.
'
It will be seen that as the wheel d¹ revolves once for every 100 gallons of liquid
withdrawn from the vessel the sector r will indicate the number of hundreds of
gallons and that the pinion y revolving ten times for each revolution of the wheel
will cause the hand a¹ at each complete turn to indicate 100 lbs. equal to 10 gallons.
Also that as the wheel d'executes a quarter of a revolution for each turn of the
wheel c' it will cause the haud in a complete turn to indicate 4,000 lbs. or 4 feet
which are equal to 400 gallons, the total capacity of the vessel.
Some or all of the graduations are advantageously marked so as to read
backwards as well as forwards in order to more clearly indicate while the vessel is
being filled.
"
The counting mechanism illustrated in Figures 10 and 11 is the same as that
hereinbefore described with reference to Figures 5 and 6 except that all the
graduated circles are concentric with one another and the hand or pointer a¹ is
therefore arranged to move on the same axis as the two other hands or pointers j
and k
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 liquid gauge comprising a float suspended from a cord or chain wound
around a drum, a spring for moving the drum in a reverse direction to that in
which it is moved by the float, and counting mechanism adapted to be operated
by the drum, substantially as and for the purpose hereinbefore described.
2. The improved liquid gauges hereinbefore described with reference to Figures 1
to 4, Figures 5 to 9 and Figures 10 and 11 of the accompanying drawings.
