We, THE YORK GLASS COMPANY, LIMITED, of Fishergate, York, in the County of
York, Glass Manufacturers, and JAMES BUTLER, of the same place, Works Manager,
do hereby declare the nature of this invention to be as follows:-
This invention relates to measures employed for accurately measuring liquids in
carrying out chemical and other experiments, tests, analytical inspections, and the
like and which comprise cylindrical glasses of varying sizes each having its own
quantitative graduated scale marked thereon in cubic centimeters at a given degree
centigrade.
The object of our invention is to construct the said measures so that for corres-
ponding scales of measurements we obtain measures of considerably reduced diameters
(and approximately the same lengths or less) which admit of more graduations being
marked off on the scales and consequently of more correct results being achieved by
said measures than by the ordinary measures.
For the purpose of our invention we construct or form the measure with a bulb,
enlargement or globe at the base thereof of such a size relatively to the measure as
will contain the whole or approximately the whole quantity of the liquid or body to
be measured which is below the zero point of the scale. By thus forming an en-
enlarged chamber to contain so much of the liquid as is below the scale of measure-
ment, we can considerably reduce the diameter of the upper part of the measure
whereon the graduated scale is marked and thus increase the graduations on said
scale whereby finer readings are given and more "correct results obtained. This is
accomplished also without practically adding to the height or length of the measure,
and in many cases, especially in the larger sizes, we are able to reduce the height very
materially and make the measure of a more practicable size than has heretofore been
possible.
The measures are made in sizes to suit the several standards of measurement em-
ployed and the bulb or enlarged base is of any suitable shape or configuration.

improvements in Graduated Liquid Measures.
We, THE YORK GLASS COMPANY, LIMITED, of Fishergate, York, in the County of
York, Glass Manufacturers, and JAMES BUTLER, of the same place, Works Manager,
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:-
This invention relates to measures employed for accurately measuring liquids in

page_text: carrying out chemical and other experiments, tests, analytical inspections, and the
like, and which comprise cylindrical glasses of varying sizes each having its own
quantitative graduated scale marked thereon in cubic centimetres at a given degree
Centigrade.
The object of our invention is to construct the said measures so that for correspond-
ing scales of measurements we obtain measures of considerably reduced diameters (and
approximately the same lengths or less) which admit of more graduations being
marked off on the scales and consequently of more correct results being achieved by
said measures than by the ordinary measures.
For the purpose of our invention we construct or form the measure with a bulb,
enlargement, or globe at the base thereof of such size relatively to the measure as
will contain the whole or approximately the whole quantity of the liquid or body to
be measured which is below the lowest measuring point of the scale.
By thus
forming an enlarged chamber to contain so much of the liquid as is below the scale of
measurement, we can considerably reduce the diameter of the upper part of the
ineasure whereon the graduated scale is marked and thus increase the graduations on
said scale whereby finer readings are given and more correct results obtained. This
is accomplished also without practically adding to the height or length of the measure,
and in many cases, especially in the larger sizes, we are able to reduce the height
very materially and make the measure of a more practicable size than has heretofore
been possible.
The accompanying drawing illustrates a measure constructed according to our
invention having a range from 50 to 100 cubic centimetres. Letter a represents a
bulb or enlargement at the base of the measure said bulb a being, as shewn, of such
size, relatively, as to contain the whole or approximately the whole of the liquid to be
measured up to the lowest reading of the scale c. By forming the measure with an
enlargement a we are enabled to considerably reduce the diameter of the measure at
the upper part thereof, or part carrying the graduated scale. By this means finer
readings are given and consequently more accurate results can be obtained, and this
is accomplished with a decrease in the height of the measure as compared with that
of a measure of similar capacity of the form at present in use, this being especially
the case in measures of large capacity, or if the measure be constructed the same
height as hitherto we are enabled to get a longer scale which can thus be graduated
more finely.
The measures are made of various sizes and capacities and the scale thereon may be
graduated to any standard of measurement either from 50 upwards, or from 500
upwards or as may otherwise be determined.
The bulb or enlargement a may be of any suitable shape or configuration according
to taste or requirements. The aforesaid measures by reason of the increased base are
not as liable to be upset as the ordinary measures.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A graduated liquid measure of the description specified having an enlargement or
bulb at the base thereof of such capacity that the whole or approximately the whole
of the liquid or substance up to the lowest reading on the scale shall be contained
within said enlarged base or bulb substantially as herein shewn and described and for
purposes set forth.
