IMPROVE- MENTS IN WATCHES AND OTHER TIMEKEEPERS
Year: 1862

page_text: LETTERS PATENT to Frederick Bonaparte Anderson, of Birmingham, in
the County of Warwick, Manufacturer, for the Invention of "IMPROVE-
MENTS IN WATCHES AND OTHER TIMEKEEPERS."
Sealed the 26th June 1868, and dated the 30th December 1862.
PROVISIONAL SPECIFICATION left by the said Frederick Bonaparte
Anderson at the Office of the Commissioners of Patents, with his
Petition, on the 30th December 1862.
I, FREDERICK BONAPARTE ANDERSON, of Birmingham, in. the County of
5 Warwick, Manufacturer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN WATCHES AND OTHER TIMEKEEPERS," to be as
follows:-
My Invention consists in constructing those parts of watches and othe
timekeepers known as hollow fusees, and as stops to prevent the mainspring
O from being overwound, as hereafter described.
I form a disc on the arbor, by preference in a piece with it, and sink a rocess
in the outside of the fusee brass into which the disc is fitted and secured by
soldering or other attachment. I form a square on the back of the arbor to
receive what I term a gatherer or stop which works inside a steel split ring
5 formed with three or more teeth, and with an abutment on the inside thereof.

page_text: As the watch is wound the gatherer takes round a tooth at every complete
revolution until the spring is wound up, when the gatherer comes in contact
with the abutment, and prevents overwinding. The split ring is encased in a
box fastened on to the back of the pillar plate.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Bonaparte Anderson in the Great Seal Patent
Office on the 29th June 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BONAPARTE ANDERSON, of Birmingham, in the County of Warwick, Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of December, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth 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 particularly.
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 :-
⚫ My Invention consists in constructing those parts of watches and other

page_text: timekeepers known as hollow fusees, and as stops to prevent the mainspring
from being overwound, as hereafter described.
I form a disc on the arbor, by preference in a piece with it, and sink a recess
in the outside of the fusee brass, into which the disc is fitted and secured by
soldering or other attachment. I form a square on the back of the arbor to
receive what I term a gatherer or stop which works inside a steel split ring
formed with three or more teeth, and with an abutment on the inside thereof.
As the watch is wound the gatherer takes round a tooth at every complete
revolution until the spring is wound up, when the gatherer comes in contact
with the abutment, and prevents overwinding. The split ring is encased in a
box fastened on to the back of the pillar plate.
Figure 1 of the accompanying Drawings shews in section a hollow fusee
constructed according to my Invention, by which I am enabled to dispence
with the ordinary cap and inside stopwork. I form a disc a on the arbor b, by
preference in a piece with it, and sink a recess c in the outside of the fuseo
brass, into which the disc a is fitted, and secured by solder or otherwise.
Figure 2 is another form of hollow fusee, in which also the cap and inside
stopwork are dispensed with, and the ratchet with the arbor screwed on at
back.
Figures 3 and 4 are respectively front and back views of the fusce repre-
sented in Figure 2. I form a square d on the back of the arbor 6 to receivo
behind the pillar plate a gatherer or stop e, Figure 5, which works inside a
steel split ring f, formed with teeth g, and with an abutment h on the inside
thereof. As the watch is wound the gatherer e takes round a tooth at every
complete revolution until the spring is wound up, when the gatherer comes in
contact with the abutment h, and prevents overwinding.
Instead of forming the teeth on the inside of a split ring, as shewn in
Figure 5, in some cases I employ a toothed disc, as represented in Figure 6,
and fasten it by a screw i, or otherwise, to the back of the pillar plate. I also
attach a spring to the back of the pillar plate, which presses upon the side
or top of the disc and retains it in position. I leave a strong circular pro-
jection or "lob" in the centre of the ordinary recess or hollow on the under
side of the upper plate, as shewn at k, Figure 7, and cut a slot / to form a
passage for the chain from the fusee to the barrel.
And having now described the nature of my said Invention, and in what
nanner the same is to be performed, I declare that I claim as my "Improve-
ments in Watches and other Timekeepers,"-
First, forming a disc on the arbor and a recess in the outside of the brass

page_text: of hollow fusees into which the disc is fitted, as herein-before described and
illustrated in Figure 1 of the accompanying Drawings.
Second, constructing hollow fusees in manner represented at Figure 2 of
the accompanying Drawings.
Third, the employment of a gatherer or stop on a square on the back of the
fusee arbor, which gatherer or stop works inside a steel split ring formed with
teeth, and with an abutment on the inside thereof, as represented in Figure 5,
or which takes into a toothed disc, as represented in Figure 6, for the purpose
herein-before described.
Fourth, forming a circular projection or "lob" in the centre of the ordinary
recess or hollow on the under side of the upper plate, and a slot between the
fusee and the barrel, in manner and for the purpose herein-before described
and represented in Figure 7 of the accompanying Drawings.
In witness whereof, I, the said Frederick Bonaparte Anderson, have
set my hand and seal, this Twenty-second day of June, One thousand 1
⚫eight hundred and sixty-three. .
