IMPROVE- MENTS IN GUARDS FOR POCKET-BOOKS, WATCHES, AND WATCH KEYS."
Year: 1866

page_text: LETTERS PATENT to John Macintosh, of North Bank, Regent's Park, in
the County of Middlesex, and William Boggett, of Lindsey Houses,
Chelsea, in the County of Middlesex, for the Invention of "IMPROVE-
MENTS IN GUARDS FOR POCKET-BOOKS, WATCHES, AND WATCH KEYS."
PROVISIONAL SPECIFICATION left by the said John Macintosh and
William Boggett at the Office of the Commissioners of Patents, with
their Petition, on the 21st April 1866.
I, JOHN MACINTOSH, of North Bank, Regent's Park, in the County of
Middlesex, and I, WILLIAM BOGGETT, of Lindsey Houses, Chelsea, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN GUARDS FOR POCKET-BOOKS, WATCHES, AND WATCH KEYS,"
to be as follows:-
Our Invention consists in the use of elastic materials to prevent pocket-
books being lost or mislaid, watches being stolen from the person, and in
protecting the works of watches from injury caused by the dirt so frequently
found in the pipes of watch keys.
The first-mentioned objects are attained in the following manner:-We
take an elastic cord made by preference of india-rubber and silk, one end of
which is fastened to the watch pocket or clothes, and the other end to the
watch or book. This arrangement admits of the watch or book being readily

page_text: accesible for inspection, whilst it would frustrate any attempt to remove them
without the wearer's knowledge.
Our second object we accomplish by inserting the pipes of watch keys into
an aperture in an elastic substance, such as cork or india-rubber with a view
to the exclusion of dust and flue which collects in them when worn loose in
the pocket, &c. The cork or india-rubber may either be used alone or
encased (which we prefer) in tubes of metal or other suitable materials, the
elastic substance retaining a firm hold of the pipe, except when the key is
wanted for use. Steel or other springs may be used for the same purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Macintosh and William Boggett in the Great Seal
Patent Office on the 20th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
MACINTOSH, of North Bank, Regent's Park, in the County of Middlesex,
and I, WILLIAM BOGGETT, of Lindsey Houses, Chelsea, in the County of
Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Macintosh and William Boggett," Her special licence that we,
the said John Macintosh and William Boggett, our executors, administrators,
and assigns, or such others as we, the said John Macintosh and William
Boggett, our 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 GUARDS
FOR POCKET-BOOKS, WATCHES, AND WATCH KEYS," upon the condition (amongst
others) that we, the said John Macintosh and William Boggett, our executors
or administrators, by an instrument in writing under our, 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.

page_text: NOW KNOW YE, that we, the said John Macintosh and William Boggett,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
Our Invention consists in the use of elastic cords or such like materials to
prevent pocket-books being lost or mislaid, watches being stolen from the
person, and in protecting the interior of watches from the injury caused by
dirt and dust in the pipes of watch keys.
The first-mentioned objects are effected in the following manner:-We
take an elastic cord, made by preference of silk covered with india-rubber, one
end of which we fasten to a piece of metal of any convenient shape, as shown
in Fig. 1, which has a sharp-pointed spiral wire, like a corkscrew, projecting
from its lower end; this being screwed into the lining of the watch pocket
holds it securely, whilst the other end of the cord is attached to that part of
the watch pendant between the bow, so that any attempt to steal it by
breaking the bow would be frustrated, the elasticity of the cord at the same
time allowing a ready means of inspection; other means of screwing the
elastic cord may be used either for watches or pocket-books, but we prefer the
one just described.
then by proper
into a tube or
retains its
Our Invention for excluding dirt from watch keys may be effected in various
ways, of which the following description and Drawings are examples; 1st,
Fig. 2 is a vertical section of a key having a sliding metal plug a accurately
fitting the pipe; this plug is attached to a spiral spring b, which allows the
plug to recede, which in the act of winding up the watch, and by the action
of the spring becomes flush with the end when not in use. Pieces of thin
sheet metal are cut into the form shown in Fig. 3, and are
tools, such as are used in making percussion caps, formed
shield, of which Fig. 4 shows a vertical section, which by its
hold when fitted on to the key pipe and effectually excludes dust and dirt. The
key pipe may with this object be inserted in a tube of cork or india-rubber.
Fig. 5 is a horizontal section of a bar, such as is commonly in use with
"Albert" chains, of which the portion from a to c forms a watch key; this key
is inserted into the other part of the bar and presses against the spiral spring
therein at a, being retained in its place by a bayonet joint at b. By this or
similar arrangements watch keys may be inserted in pencil-cases, charms, &c.
with a view to the exclusion of dirt; revolving watch keys may likewise be
protected by causing the end of the pipe to abut against a spiral or other
spring.
What we claim as our Invention is the use of covered india-rubber cords

page_text: in combination with the instrument represented in Fig. 1, or other analagous
arrangements for the protection of pocket-books and watches, and the several
methods herein described, or others of a like; character for the exclusion of
dirt from watch keys.
In witness whereof, we, the said John Macintosh and William Boggett,
have hereunto set our hands and seals, this Twentieth day of October,
in the year of our Lord One thousand eight hundred and sixty-six.
