IMPROVEMENTS IN WATCHES AND MACHINES FOR KEEPING TIME
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
MASSEY, of King Street, Clerkenwell, in the County of Middlesex, Watch
Maker, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Thirteenth day of September, in the second year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Edward Massey, Her especial licence, full power, sole privilege and authority,
that I, the said Edward Massey, my exors, admors, and assigns, or such others
as I, the said Edward Massey, 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 WATCHES AND MACHINES FOR KEEPING TIME;"
in which said Letters Patent is contained a proviso, that I, the said Edward
Massey, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, to be inrolled in
Her said 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Edward Massey, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are
and ascertained in and by the following statement thereof, reference being had
to the Drawing hereunto annexed, and to the figures and letters marked
thereon (that is to say):-
DESCRIPTION OF THE DRAWING.
Figure 1 represents a new method of making a verge for the common
balance-wheel watch. A is a flanch, in which is 'cut a notch in a line with its
axis, to receive the pallet; B is the verge collet, in which a notch is also cut
to receive the pallet C. The pallets may be made of ruby or any other pre-
cious stone that may be sufficiently hard to prevent them being cut by the
wheel. They must be cemented or otherwise secured in the notches. By this
method of making a verge, steel pallets may be made to more advantage than
at present, as they may be left perfectly hard, and cemented or otherwise
fastened in the notches. The pallet C; instead of being placed in the collet,
may have the verge filed across in the direction of the action of the wheel,
and the jewel cemented in it, but this method will be objectionable to the
lower pallet, as it will be necessary to reduce the size of the balance wheel, as
the acting part of the pallet cannot be brought so near to the foot hole. The
angle and width of the pallets are to be made in the usual way.
Figure 2 represents a verge in the usual way for a common balance wheel,
except that the pallets are placed further back or past the centre, so that when
the jewels are cemented upon them the acting part of the pallets will be
brought to their usual or proper angle.

Figure 3 represents a detached marine chronometer escapement, as made
with locking detants on pivots, with this difference, instead of straight springs
I use the springs as shown at A and B, made in the same manner as the com-
mon pendulum springs; they will be free from friction, and may be made to
act very light. This view is from the inside of the pottants plate. One or
both of these springs may be used, as may be found most convenient.
Figure 4 represents a new method of making a watch escapement for a
hand to drop seconds. A, the wheel, made similar to a duplex wheel, with
a pair of pallets B acting in it, the leading pallet C acts as a locking pallet
only on the external tooth of the wheel, and when this is unlocked the wheel
falls on the receiving pallet at D, and on the return of the balance it com-
municates the whole or nearly the whole of the impulse in one vibration
instead of two, as is usual in lever watches. This will give it the advantage
of gathering the wheel more perfectly."
Figure 5 represents a wood stand for a clock. A, the stand; B, an axis,

page_text: made stationary, with a crank at F, which connects it with pullies and endless
chains G, G, G; H, the frame of the clock; I, the barrell or fusee arbour (as
this method is applicable to clocks made with fusee or barrel only), on which is
secured the upper pulley, so that when the clock requires winding up, the key
must be introduced at B, and it may be seen that by turning it, the office of
winding the clock will be easily performed. This method of the endless chain
and pullies may be applied to different kinds of machines for keeping time,
but it is more particularly calculated for clocks with glass shades over them.
In witness whereof, I, the said Edward Massey, have hereunto set my
hand and seal, this Thirteenth day of March, in the year of our Lord
One thousand eight hundred and thirty-nine.
AND BE IT REMEMBERED, that on the Thirteenth day of March, in the
year of our Lord 1839, the aforesaid Edward Massey came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Inrolled the Thirteenth day of March, in the year of our Lord One
thousand eight hundred and thirty-nine.
