Sealed the 11th November 1862, and dated the 16th May 1862.
PROVISIONAL SPECIFICATION left by the said Frederick Bonaparte
Anderson at the Office of the Commissioners of Patents, with his
Petition, on the 16th May 1862.
], FREDERICK BONAPARTE ANDERSON, of Birmingham, in the County of
Warwick, Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN WATCHES AND OTHER TIMEKEEPERS," to be as follows:-
The main object of my Invention is to obtain a maintaining power with a
fixed barrel, whereby the chain and many parts in watches as now made are
dispensed with and other advantages are gained. I form my barrel and barrel
bar or name plate in one piece, and I also form the ratchet great wheel and
barrel arbor in one piece. I place on the square of the arbor a collar or nut
with a square space in the centre to fit the square of the spindle, and I form a
hook on the outer surface of the nut to take hold of one end of the spring:
contained in the barrel, the other end of which is fixed to the side of the-
barrel. I also form the side of the barrel with apertures for the reception of
the hook or stud which holds the outer end of the spring in order that the
book or stud may be shifted from one to the other, so that the tension of the
spring may be regulated. The tension of the spring may also be regulated by:
shifting the collar to which the inner end of the spring is attached on the
arbor. Again in some cases I make the barrel and upper plate in one.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BONAPARTE ANDERSON, of Birmingham, in the County of Warwick, Manu-

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her beirs and successors, give and grant unto me, the
said Frederick Bonaparte Anderson, Her special licence, that I, the said
Frederick Bonaparte Anderson, my executors, administrators, and assigns, or
such others as I, the said Frederick Bonaparte Anderson, my executors,
administrators, and assigns, should at any time agree with, and no others,.
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands,
and Isle of Man, an Invention for. "IMPROVEMENTS IN WATCHES AND OTHER
TIMEKEEPERS," upon the condition (amongst others) that .I, the said Frederick
Bonaparte Anderson, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Frederick Bonaparte Anderson, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say :-
The object of my Invention is to obtain a maintaining power with a fixed
barrel, whereby the chain and many parts in watches as now- made are
dispensed with and other advantages are gained. I form my barrel and barrel
bar or name plate in one piece, and I also form the ratchet, great wheel, and
barrel arbor in one piece. I place in the barrel a collar or nut with a square
space in the centre to fit the square of the spindle of the arbor, and I form a
hook on the outer surface of the nut to take hold of one end of the spring
contained in the barrel, the other end of which is fixed to the side of the

page_text: barrel. I also form the side of the barrel with apertures for the reception of
the book or stud which holds the outer end of the spring in order that the
hook or stud may be shifted from one to the other, so that the tension of the
spring may be regulated. The tension of the spring may also be regulated
by shifting the collar to which the inner end of the spring is attached
on the arbor. Again in some cases I make the barrel and upper plate
in one.
Figure 1 of the accompanying Drawings is a plan of the under side of a
barrel and barrel bar made in one piece according to my Invention; Figure 2
is a plan of the top plate on which the barrel and barrel bar are fitted;
Figure 3 is a plan of the under side of a top plate with a barrel made in
a piece with it; Figure 4 is a side view; Figure 5 is an edge view, and
Figure 6 a section of the same; Figure 7 is a view of a collar or nut which is
fitted in the barrel.
a is the nut in the barrel, it rests on a flange formed on the bottom of the
barrel, and at top it is secured by the barrel cover b. A hole c is made
through the nut a, the surface of which is cupped to receive the great wheel
arbor d, shown at Figure 8. e is the hook on the nut a to hold the inner end
of the spring contained in the barrel.
Figure 9 is a view showing the great wheel arbor and ratchet, carrying the
great wheel going ratchet and spring fitted to the barrel and nut a, as they
appear when in action; Figure 10 is a plan of a pillar plate fitted with a detent
taking into the teeth of the going ratchet; Figure 11 is a plan of a plate to
which a barrel, shown at Figure 12, is secured by screws.
through which the screws pass and enter the plate.
9, 9, are the lugs
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my "Improve-
ments in Watches and other Timekeepers," obtaining a maintaining power
with a fixed barrel, substantially in manner herein-before described and illus-
trated in the accompanying Drawings.
In witness whereof, I, the said Frederick Bonapartę Anderson, have
hereunto set my hand and seal, this Fourteenth day of November,
One thousand eight hundred and sixty-two.
