I JAMES JOSEPH HICKS of 8 Hatton Garden in the County of Middlesex
Meteorological Instrument Manufacturer do hereby declare the nature of said
Invention to be as follows:-
The invention relates principally to metal hydrometers and saccharometers but is
also applicable to such instruments when made of glass and consists of certain
additions thereto whereby the hydrometer or saccharometer is prevented from
revolving in the fluid in which it is immersed, and when out of the said fluid it may
bo stood upright whilst if so desired the said additional parts may be so constructed
as to serve as a guard to the floating bulb by preventing the possibility of the
hydrometer or saccharometer being laid down on a table or other flat surface with the
said bulb touching such surface.
For this purpose I braze, solder or otherwise connect to the lower end of the stem
of a metal hydrometer or saccharometer a number of wings or projections preferably
flat and which are so formed as to serve as convenient feet upon which the
hydrometer can be stood when not in the fluid and which will also prevent the rotation
of the hydrometer when in the fluid. In some cases I make these wings, projections
or feet to extend sufficiently far from the stem to serve as a guard to the floating bulb,
so that when the hydrometer or saccharometer is laid down on a table or other flat
surface it shall be supported by the upper end of the stem and by the wings,
projections or feet with the floating bulb free from contact with such table or other
flat surface.
In applying my invention to glass hydrometers or saccharometers I fuse on to the
weighting bulb or on to the lower part of the stem plates or blades of glass which
may be made to serve all or any of the purposes above described with reference to
metal hydrometer and saccharometers.

I, JAMES JOSEPH HICKS of 8 Hatton Garden, in the County of Middlesex,
Meteorological Instrument Manufacturer 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 invention relates principally to metal hydrometers and saccharometers, but is 5
also applicable to such instruments when made of glass and consists of certain
additions thereto whereby the hydrometer or saccharometer is prevented from revolving
in the fluid in which it is immersed, and when out of the said fluid it may be stood
upright whilst if so desired the said additional parts may be so constructed as to serve
as a guard to the floating bulb by preventing the possibility of the hydrometer or
saccharometer being laid down on a table or other flat surface with the said bulb
touching such surface.
For this purpose I braze, solder or otherwise connect to the lower end of the stem
of a metal hydrometer or saccharometer a number of wings or projections, preferably
flat, and which are so formed as to serve as convenient feet upon which the
hydrometer can be stood when not in the fluid and which will also prevent the rotation
of the hydrometer when in the fluid. In some cases I make these wings, projections,
or feet, to extend sufficiently far from the stem to serve as a guard to the floating
bulb so that when the hydrometer or saccharometer is laid down on a table or other
flat surface it shall be supported by the upper end of the stem and by the wings,
projections or feet with the floating bulb free from contact with such table or other
flat surface.
In applying my invention to glass hydrometers or saccharometers I fuse on to the
weighting bulb, or on the lower part of the stem, plates or blades of glass which
may be made to serve all or any of the purposes above described with reference to
metal hydrometers and saccharometers.
And in order that my said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully to
describe the same.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 represent respectively an elevation and an underside view of my
improved metal hydrometer and Figures 3 and 4 are similar views of my improved
metal saccharometer and Figures 5 and 6 and 7 and 8 are respectively similar views
of my improved glass hydrometers known respectively as a hydrometer and
urinometer: In all the figures like parts are indicated by similar letters of reference.
a represents the floating bulb, 6 the weighting bulb or weight and c the stem which
in the case of the metal hydrometer and saccharometer, shown at Figures 1 to 4, is

page_text: itself divided to the proper scale whilst in the case of the glass instruments, shown at
Figures 5 to 8, the scale, which is of enamel glass is contained within the hollow glass
stem c and is supported at its lower end by an internal contraction in such stem and
is hermetically sealed therein so that it cannot possibly move.
The metal hydrometer (Figures 1 and 2) is weighted by removeable weights b
threaded on the lower stem d and the metal saccharometer (Figures. 3 and 4) is
weighted by removeable weights b formed with a slightly tapered stem 6 which fits
tightly into a hole formed in the lower end of the stem d, by which means the said
hydrometer and saccharometer are capable of being variously weighted as is well
understood.
The glass instruments are formed with a fixedly weighted bulb 6 as is also well
understood.
According to my present invention I braze, solder or otherwise connect to the
lower end of the lower stem d of the metal hydrometer and saccharometer a number
of wings or projections e, preferably flat, and which are so formed as to serve as
convenient feet upon which the hydrometer or saccharometer can be stood when not
in the fluid and which will also prevent the rotation of the hydrometer and
saccharometer when in the fluid.
In some cases 1 make these wings, projections or feet to extend, as shown by the
dotted lines, sufficiently far from the stem to serve as a guard to the floating bulb a
so that when the hydrometer or saccharometer is laid down on a table or other flat
surface it shall be supported by the upper end of the stem c and by the wings,
projections or feet e, with the floating bulb a free from contact with such table or other
flat surface.
In the glass instruments I fuse on to the weighting bulb 6 or on to the lower part
of the lower stem, plates or blades e of glass which may be made to serve all or any of
the purposes above described; in the drawings I have represented these plates or
blades e by the full lines as serving the purpose of feet and to prevent rotation of the
instrument in the liquid, whilst by the dotted lines I have represented such plates or
blades e to serve also as guards to the floating bulbs a as above described with
reference to the metal hydrometer and saccharometer.
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 metal hydrometers and saccharometers the fixing thereto of wings, projections
or feet substantially as herein shown and described and for the purpose stated.
2. In glass bydrometers and saccharometers the fusing to the weighting bulb or to
the lower part of the stem, of blades or plates of glass substantially as herein shown
and described and for the purpose stated.
