Year: 1801

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, TIMOTIIY
LANE, of Lincoln's Inn Fields, in the County of Middlesex, send greeting.
WHEREAS His Majesty King George the Third, by His Letters Patent
under the Great Seal of Great Britain, bearing date at Westminster, the.
Fifth day of June, in the forty-first year of His reign, did give and grant unto
me, the said Timothy Lane, His especial licence that I, the said Timothy
Lane, during the term of years therein mentioned, should and lawfully might
use, exercise, and vend, within England and Wales, and the Town of Berwick-
upon-Tweed, my Invention for "A METHOD WHEREBY MEASURING GLASSES MAY
BE RENDERED VERY ACCURATE, BY A MEANS DIFFERING FROM ANY AT PRESENT IN
USE IN THE EXACT COMPOUNDING OF MEDICINES, AND FOR OTHER PURPOSES WHERE
CORRECT MEASURES ARE WANTED;" in which said Letters Patent is contained
a proviso, obliging me, the said Timothy Lane, by an instrument in writing
under my hand and seal, to cause a particular description of the nature of
my said Invention, and in what manner the same is to be performed, to be
inrolled in His Majesty's High Court of Chancery within one calendar
month after the date of the said Letters Patent, as by the same, relation
being thereunto had, may appear.
NOW KNOW YE, that in compliance with such proviso, I, the said
Timothy Lane, do hereby declare that my said Invention is described in
manner following, that is to say:-
The weight of a gallon of distilled water is to be ascertained in troy grains,
whether of wine or beer measure, whereby, either by addition or division, the
proper proportions of all the graduations requisite for any measure may be

page_text: known in troy grains and parts of a grain, by having weights and scales adapted
to the various purposes. To measures having a large surface, the surface is
needful to be attended to; the inaccuracy arising from thence is to be
corrected by marks added to direct the eye to the same level, as when they
were first graduated. When made with glass (two surfaces being seen through
glass containing transparent fluids), divisions are to be made corresponding
with the upper and under surfaces, if required. When lines are required for
additional accuracy, the marks will serve as a guide, whereby they may be
described. When glass is not best adapted to the uses graduated measures
may be wanted for, they are to be made of other substances. To distinguish
the measures made under the above Patent from other measures, the name of
"Lane" is intended to be affixed to them.
In witness whereof, I, the said Timothy Lane, have hereunto set my
hand and seal, the Thirtieth day of June, in the year of our Lord
One thousand eight hundred and one.
AND BE IT REMEMBERED, that on the same Thirtieth day of June,
in the year above mentioned, the aforesaid Timothy Lane came before our
Lord the King in His Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained, in form above written.
And also the Specification aforesaid was stamped according to the tenor of
the Statute in that case made and provided.
Inrolled the same Thirtieth day of June, in the year above written.
