years from the date of the said Letters Patent next and immediately ensuing,
and fully to be compleat and ended according to the Statute in such case
made and provided; in which said Letters Patent there is contained a proviso
obliging me, the said Joshua Lover Martin, 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 four calendar months next
and immediately after the date of the said Letters Patent, as in and by
the same (relation being thereunto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Joshua Lover Martin, do hereby declare that the nature of my said
Invention, and the manner in which it is to be performed, is as follows,
videlicet :-
The copper or metals to be plated is first covered with silver or gold, and
afterwards formed into tubes and soldered. They are then applied to the
draw bench, and, being first put on a triblet or mandril, are drawn through
the holes of different sizes according to the required thickness of the tubes.
This being done, they are made into telescopes, perspectives, opera glasses,
or other optical, mathematical, or philosophical instruments, where plated
tubes may be required. And to prevent the surface of the plated metal tubes,
in the necessary action of sliding, from being sratched or otherwise defaced
(which would be the consequence of tubes sliding in metal), the collars or
springs thro' which the plated tubes are made to slide is lined with cloth,
velvet, or other soft substance.
In witness whereof, I, the said Joshua Lover Martin, have hereunto set
my hand and seal, this Twenty-eighth day of March, in the twenty-
second year of the reign of our Sovereign Lord George the Third, by
grace of God of Great Britain, France, and Ireland King, Defender
of the Faith, and so forth, and in the year of our Lord One thousand
seven hundred and eighty-two.
