FREEMANTLE, of Aldersgate Street, London, Watchmaker, send greeting..
WHEREAS I, the said William Freemantle, have, after much study, dis-
covered "AN IMPROVEMENT ON THE VERTICAL WEIGHT AND SPRING ROASTING
JACKS, WHICH RENDER THE SAME LESS COMPLICATED ;" and whereas, upon repre-
senting the same to His present Majesty King George the Third; His said
Majesty, by Letters Patent under the Great Seal of Great Britain, bearing
date the Twenty-fourth day of March, in the thirtieth year of His said Majes-
tie's reign, did give and grant unto me, the said William Freemantle, my exe-
cutors, administrators, and assigns, specialt licence, full power, sole priviledge and
authority, that I, the said William Freemantle, my executors, administrators,
and assigns, and every of them, by myself and themselves, or by my and
their deputy or deputies, servants or agents, or such others as I, the said
William Freemantle, my executors, administrators, or assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term of years therein expressed, should and lawfully might make,
use, exercise; and vend my said Invention, within that part of the Kingdom of
Great Britain called England, the Dominion of Wales, and Town of Berwick-
upon-Tweed, in such manner as to me, the said William Freemantle, my
executors, administrators, or assigns, or any of them, should in my or their
discretions seem meet; and that I, the said William Freemantle, my executors,
administrators, and assigns, should and lawfully might have and enjoy the whole
profit, benefit, commodity, and advantage from time to time coming, growing,

page_text: accruing, and arising, by reason of the said Invention, for and during the term
of years therein mentioned; to have, hold, exercise, and enjoy the said licence,
powers, privileges, and advantages therein-before granted or mentioned to be
granted unto me, the said William Freemantle, my executors, administrators,
and assigns, for and during and unto the full end and term of fourteen 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 is contained a proviso that
if I, the said William Freemantle, should not particularly describe and ascer-
tain 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, and
cause the same to be inrolled in Tis Majestie's High Court of Chancery
within one calendar month next and immediately after the date of the said
Letters Patent, that then the said Letters Patent, and all liberties and
advantages whatsoever thereby granted, should utterly cease, determine, and
become void, anything in the said Letters Patent contained to the contrary
thereof in anywise notwithstandin, as in and by the said recited Letters Patent,
relation being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Freemantle, do hereby declare that my Invention of an Improvement
on the Vertical Weight and Spring Roasting Jacks is described in manner
following (that is to say):
=
My Invention of an Improvement on the Vertical Spring Roasting Jack
consists of a circular plate A, B, C, D, a plan of which vertical spring roasting
jack is drawn in the margin of these Presents); and another plate 9. I, I, I,
connected by means of three pillars about three inches in length, rivetted into
the said plates at E, F, G. In the same frame, and with its axis parallel to
the plates, a contrate wheel b, c, having thirty teeth, is turned by a spring,
making about seven turus in a barrell, d, d, d, d, fixed to the plate h. h, which
is screwed to the pillars E and F, in which plate the pivot m of the wheel b, c,
turns. The pivot 2, 7, turns in the pillar G; at one inch and a quarter from the
upper end of the said pillar, the part 1, 1, of the arbour is square, as there
the machine is wound up. n, n, is a rotchet rivetted to the brass collett o, o ;
the wheel, of course, is furnished with a click. The teeth of the wheel b, c,
are of this figure, and act in a common verge (whose center is at a),
in the usual manner; on the said verge, and near the lower end, an arc or rack
i, i, i, i, having about forty teeth, is fixed, which gives motion to a suspended
pinion at H, having six leaves to this pinion. The meat is suspended in the
usual manner; concentric with the hole is fixed a tin tube, about seven

page_text: inches long, from the top of which the pinion is suspended by a silk string.
The apparatus to prevent over winding is, by means of a pinion, fixed on the
pivott m, which takes into a stop wheel. When the above jacks are designed to
be fixed on a screen, the bottom plate may be made square, as W, X, Y, Z,
for the convenience of sliding in a groove on the top of the screen, for the
purpose of drawing the meat to and from the fire occasionally. The jack
above described I call my Improved Vertical Spring Roasting Jack.
My Weight Jack is on the same principle, except that the spring and spring
barrell are omitted, and on the arbour of the wheel a barrell is fixed, round
which the line to which the weight hangs is wound. The verge, arbour of the
wheel, &c., are made of steel, the rest of the work is brass; the whole is
enclosed in a circular tin case, but may be made of any other metal or
figure.
In witness whereof, I, the said William Freemantle, have hereunto set
my hand and seal, this Thirteenth day of April, in the year of our
Lord One thousand seven hundred and ninety.
