PROVISIONAL SPECIFICATION.
Improvements in and connected with Watch Keys.
I, PHILIP HENRY LAWRENCE, of 158, Coventry Road, Birmingham, in the
County of Warwick, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the manner in which I construct a watch key for
attaching to chains, pendants, guards and other like articles, whereby I am enabled
to wind and set the watch without in any way interfering with the attachment of
the watch to the chain or other object.
In carrying my invention into effect I construct a watch key having two bow
ends, or a loop shaped attachment for the centre or key carrying link. Within this
bow ended or loopshaped centre piece I form a central boss or eye through which I
drill or form a hole to receive a key spindle. The key spindle I construct with a
circular body, and preferably with a recessed or shouldered end, so that the end or
portion within which the square is formed, cannot possibly be pulled or slip through
the centre piece. Upon the upper portion of the key spindle I form a thread or
screw to receive a bow or ring shaped manipulating handle; and to further secure
the handle or turning portion to the spindle of the key, I sometimes pin the one to
the other in addition to screwing the one direct to the other.
I do not always attach the manipulating handle to the key spindle by screwing
although I prefer to do so for greater security, but when constructing commoner
combined links and keys according to my present invention, I sometimes rivet the
keys to the bows or handles in the usual or ordinary manner.
The shape of the link or end portions of my improved key I vary to suit any
particular chain or ornament to which it may be required to attach the key; and in
like manner I construct the manipulating bow or handle to suit the design of the
chain or pendant. I do not always make the handle in the form of a bow or loop
but instead construct it as a globe, square or other ornamental shape.
Thus when my improved key is attached to any watch chain or guard, it is
possible to move the key quite freely when hanging and secured to the chain,
and thus to wind or set the watch without disconnecting the chain from the bow of
the watch.

COMPLETE SPECIFICATION.
Improvements in and connected with Watch Keys.
I, PHILIP HENRY LAWRENCE, of 158, Coventry Road, Birmingham, in the
County of Warwick, Manufacturer, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention relates to the manner in which I construct a watch key for
attaching to chains, pendants, guards, and other like articles, whereby I am enabled
to wind and set the watch without in any way interfering with the attachment of
the watch to the chain or other object.
In carrying my invention into effect I construct a watch key having two bow
ends, or a loop shaped attachment for the centre or key carrying link. Within
this bow ended or loop shaped centre piece 1 form a central boss or eye through

page_text: which drill or form a hole to receive a key spindle. The key spindle I construct
with a circular body, and preferably with a recessed or shouldered end, so that the
end or portion within which the square is formed, cannot possibly be pulled or slip
through the centre piece. Upon the upper portion of the key spindle I form a
thread or screw to receive a bow or ring shaped manipulating handle, and to further
secure the handle or turning portion to the spindle of the key, 1 sometimes pin the
one to the other in addition to screwing the one direct to the other.
I do not always attach the manipulating handle to the key spindle by screwing
although I prefer to do so for greater security, but when constructing commoner
combined links and keys according to my present invention, 1 sometimes rivet the
keys to the bows or handles in the usual or ordinary manner. The shape of the
link or end portions of my improved key, I vary to suit any particular chain or
ornament to which it may be required to attach the key; and in like manner I
construct the manipulating bow or handle to suit the design of the chain or pendant.
I do not always make the handle in the form of a bow or loop, but instead construct
it as a globe, square or other ornamental shape. Thus when my improved key is
attached to any watch chain or guard, it is possible to move the key quite freely
when hanging, and secured to the chain, and thus to wind or set the watch without
disconnecting the chain from the bow of the watch.
In the accompanying sheet of explanatory drawings
Figure is a front elevation of my improved watch key A when attached by
means of my specially formed link B B B to an ordinary watch chain H and
Swivel E.
Figure 2 is a plan of the same.
Figure 3 is a side elevation of my improved watch key A when carried within the
link attachment F, F, F, and
Figure 4 is an end view of the same.
Figure 5 is a front elevation of an alternative method of arrangement which 1
sometimes adopt by forming a special link G with a central boss plate G¹ to carry
my key A or I alter any existing wide link chain to suit, by attaching the central
boss chamber G to the sides of the link which is to have my key attached.
Figure 6 is a plan of the arrangement.
The key A is free to turn within the plate or boss portion of the link such
as G, F & B, the bow, loop, or knob C of the key being attached to the end of the
key stem by screwing, pinning, or any usual or well known method of jointing.
The underside of the key A 1 form with a shoulder of a larger diameter than the
stem portion A¹ of my key, thus preventing any movement of the key laterally.
The key revolving quite freely within the loop, ring or chain permits of the watch
being wound or set without disturbing the key from the chain and without discon-
necting the chain from the watch pendant.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is
1. The construction and arrangement of a watch key within a chain whereby the
watch can be wound and set without removing the chain from the watch, substantially
as hereinbefore described and as set forth.
2. The construction of a watch key for attachment to the link of an ordinary or
special chain link, by means of a centre plate or boss formed upon or attached to the
saine, substantially as hereinbefore described and as set forth."
3. The construction of a chain link having a central plate, boss or loop to receive
a watch key substantially as hereinbefore described and as set forth.
