Patent under the Great Seal of the United Kingdom of Great Britain and
Ireland, bearing date at Westminster, the Twenty-sixth day of May, now last

the said Joseph Anthony Berrollas, my executors, administrators, and assigns,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "A WARNING
WATCH ON A NEW CONSTRUCTION;" in which Letters Patent there is con-
tained a proviso, obliging me, the said Joseph Anthony Berrollas, under my

page_text: ascertained by the Drawings in the margin of these Presents, and by the
following description thereof, that is to say:
The inside of the movement is not different from a common watch, excepting
a barrel, which is fixed with two screws on the under side of the top plate as
near to the mainspring as possible. The arbor of the side barrel is made in the
same manner as a clock watch, has a brass wheel with sixty teeth, with a steel
wheel fixed to it, which steel wheel has thirty-three teeth, cut like a ratchet,
which cause the hammer to act. This hammer is placed between the main and
warning barrels, and the side hammer strikes on a bell spring, which bell spring
is fixed with two screws on the pillar plate. The spring in the warning barrell is
wound up five times, which occasions the hammer to give one hundred and sixty-
five knocks on the bell spring. Opposite the hammer is a pinion with six teeth
which act in the arbor wheel; this pinion is planted on one side of the upper
plate, and on the other in a bar on the back of the pillar plate A, see Drawing
in the margin. On the side pinion is a wheel with forty-five teeth B, which
wheel acts in a pinion with six teeth, planted in the bar A, on one side, and in
the pillar plate on the other. On the said pinion is a wheel with twenty teeth,
like a ratchet C, which acts in a pallett D, planted in the pillar plate on.
one side, and in a bar E, on the other, which form all the warning parts.
The motion part is the same as a common watch, with a common pinion,
having twelve teeth, and a minute wheel with thirty-six teeth, the minute
pinion with ten teeth, and the horn wheel with forty teeth; the detent of the
warning is in two parts, F and G. F is a steel piece, made in two parts;-one
is a square piece, which acts in a square hole on the hour wheel H; the other
part forms a screw head. G is a round steel pieco, with a notch, which is
fixed on the wheel I; the detent-is-made in action from the piece K, which
is a swipe of steel made in four pieces. No. 1 is fixed with a screw-on-the-
pillar plate; No. 2 is fixed on No. 1 with a screw; No. 3 and No. 4 are fixed
with two screws on No. 2. L is a spring that lays upon No. 2, and presses tlie
swipe K down, and makes No. 3 and No. 4 rise against the hour. wheel H.
The under part of F moves up No. 3, the upper part moves upon G'; when F
moves on G, L keeps down No. 3 and No. 4 near the pillar plate, and in the
same time No. 4 stops the pallet D; when the upper part of F slips in the
natch of G, No. 3 and 4 rise, and No. 4 frees the pallet. D, and the warning
is given. The hour hand-is fixed on the collets of the hour wheel H, and
must be in the same line with F. The warning hand M is fixed on the collet.
of the wheel I, and must be on the same line with the notch G..
Description of the outside of the watch. The pendant N has the form of
an acorn, which is in two parts; the upper part o is fixed upon a steel arbor,

page_text: which acts in the pendant, and has in the inside of a case a small wheel which
acts in the wheel P; the wheel Pacts in a double pinion G, which acts in
the wheel I. Between the two parts of the acorn is a little ratchet wheel with
a click and spring, which prevents the wrong action of the acorn. On turning
the part O, P, Q and I come in action, and set the warning hand M to such
hour as may be required. The warning R is a sliding piece of the same metal
as the case; on one side is engraved the letter S and on the other W. In the
inside of the case is a screw which acts upon No. 2, Fig. K. When R is
pushed to the side S, K is not in action, and all communication with the
warning and the movement is cut off. When R is pushed to the side W
the communication with the warning and the movement is established.
In witness whereof, I, the said Joseph Anthony Berrollas, have hereunto
set my hand and seal, this Nineteenth day of July, in the fiftieth year
of the reign of King George the Third, by the grace of God of the
United Kingdom of Great Britain and Ireland King, Defender of
Faith, and in the year of our Lord One thousand eight hundred
