page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
STEDMAN GILLETT, of Wilton Street, Grosvenor Place, in the County of
Middlesex, Esquire, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent, under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twelfth day of October,
(One thousand eight hundred and forty-nine,) in the thirteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Stedman Gillett, my exors, adñiors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said William
Stedman Gillett, my exors, admors, and assigns, or such others as I, the said
William Stedman Gillett, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "IMPROVEMENTS IN PACKING PISTONS, STUPPING BOXES, SLIDES,
AND OTHER PARTS OF MACHINERY, AND IN FORMING BEARINGS, AND IN MAKING
CYLINDERS AND OTHER FORMS OF METAL;" in which said Letters Patent is con-
tained a proviso that I, the said William Stedman Gillett, shall cause a
particular description of the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand and
seal, to be inrolled in Her Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.

parts of machinery where the moving parts require to be expanded from time
to time. In making cylinders and other hollow forms, such for instance as a
cylinder for an hydrostatic press, where great strength is required and no wear,
then other metals than those which will roll may be employed, according to
the object to be attained, a series of dished rings of metal being piled together,
having by preference a metal cylinder or other hollow form within (but this is
not absolutely necessary), and then by having end covers or rings or end plates
with screw bolts to draw them together, the series of discs or plates may thus
compress, and the series of dished rings or discs be held strongly together, by
which the whole cylinder or other form will be made of great strength, and
far greater than by casting or other means of making, and in like manner
other hollow forms than cylinders may be made, using dished plates of the
desired figure, with their centre portions removed.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I do not confine myself to
the details herein shown and described, so long as the peculiar character of
my Invention be retained; but what I claim is, the employing a series of dished
discs or plates of metal, pressed together as packing for pistons, stuffing
boxes, slides, and other parts of machinery, and in forming bearings and
making cylinders and other forms of metal.
In witness whereof, I, the said William Stedman Gillett, have hereunto
set my hand and seal, this Tenth day of April, in the year of our
Lord One thousand eight hundred and fifty.
