page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, RICHARD
COLE, of the City of Coventry, Turner, sendeth greeting.
WHEREAS His present Majesty King George the Third hath, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fifteenth day of March, in the thirty-third year of His reign,
given and granted unto the said Richard Cole, his executors, administrators,
and assigns, licence and authority, that he, and they, and every of them, by
himself and themselves, or by his and their deputy or deputies, servants or
agents, or such others as he and they should at any time agree with, from
time to time and at all times thereafter during the term of years therein
expressed, should and might make, use, exercise, and vend his Invention of
CONSTRUCTING CERTAIN PARTS AND MOVEMENTS OF WATCHES, CLOCKS, AND
TIMEPIECES SO AS TO RENDER THE SAME MUCH MORE REGULAR AND CERTAIN IN
THEIR GOING MOTION OR DIVISION OF TIME;" and in which said Letters Patent
is contained a proviso (among other things) that if the said Richard Cole
should not particularly describe and ascertain the nature of his said Invention,
and in what manner the same is to be performed, by an instrument in writing
under his hand and seal, and cause the same to be enrolled in the High Court
of Chancery within one kalendar month next and immediately after the date of

page_text: the said Letters Patent, that then the same Letters Patent, and all liberties
and advantages thereby granted, should cease.
NOW THESE PRESENTS WITNESS, and the said Richard Cole, in
compliance with the said proviso, doth hereby declare, that the said Invention
is described in the Figures or Drawing hereunto annexed, and by the particu-
lars following, which refer to such Figures or Drawing (that is to say) :-
verge,
Fig. I., a verticle escapement, for beating, striking, and pointing seconds
or parts of seconds. Fig. II., an horizontal escapement, for beating, striking,
and pointing seconds or parts of seconds. Fig. III., the verticle escapement
dissected. A, the verticle or balance wheel, with fifteen teeth, more or less,
going twice round in one minute. The circle for shewing the progression of the
seconds may be placed upon any part of the dial. The train is calculated accord-
ing to the number of strokes or pulsations in one minute. B, the pallets or
which the balance wheel acts against; C, the pendulum spring, fastened
to the verge; D, the verge wheel, riverted on the verge, with ninety-six teeth,
more or less; twenty-four, more or less, acting in pinion E, of six teeth, more or
less, every vibration, turning the balance F.four times round, more or less,
every beat or stroke. The number of teeth in the wheels D and A and pinion
E may be varied, according to the number of beats or pulsations required in
each minute, and in proportion thereto the balance will be affected, and have
its operation on the escapement of the watch. Where the beats or pulsations
shall be required every second, the wheel, commonly called the third wheel of
the train in a watch, made (whether with an horizontal or vertical escapement)
on the ordinary principle, will be unnecessary. Fig. IV., the horizontal escape-
ment dissected. A, an horizontal wheel, with fifteen teeth, more or less, acting
in cylinder B, on which is fastened the regulating, spring C, and cylinder wheel
D, of ninety-six teeth, more or less; twenty-four of them, more or less, acting
in pinion E, of six teeth, more or less, turning the balance F four times round,
more or less, each beat or pulsation. The number of teeth in the last-
mentioned wheels D and A and pinion E may be varied, according to the
number of beats or pulsations required in each minute, and in proportion
thereto the balance will be affected, and have its operation on the escapement
of the watch.
In witness whereof, the said Richard Cole hath hereunto set his hand
