PROVISIONAL SPECIFICATION.
Improvements in or relating to Bracelets and other Articles of
Jewellery.
We JOHN COOPER SAUNDERS of the Firm of Saunders and Shepherd of
Bartlets Passage Buildings Holborn Circus in the City of London Manufacturing
Jeweller and HERMANN DREWS of Pforzheim in the Grand Duchy of Baden
Germany Manufacturing Jeweller do hereby declare the nature of this invention
to be as follows :-
-
The invention relates to means for facilitating the attachment of watches or
other articles to bracelets watch chains or other articles of jewellery.
Many devices have been suggested for this purpose but they have been designed
to receive a watch or other article of given diameter and it has been difficult or
impossible to adjust them to different sizes thereof.
Now the object of the present invention is to obtain a device adapted to receive
watches or other articles of varying diameter so that the same may be changed
at will.
For this purpose a clamp or holder is employed consisting for example of four
claws such claws being hinged or pin jointed or they might be fixed in pairs to
separate base plates or frames adapted to approach and recede from each other in
order to afford the necessary adjustment.
According to one arrangement this adjustment is obtained by means of right and
left, handed screws formed upon a spindle and engaging nuts upon the base plates
or frames and actuated by a watch key fitting a square thereon or by other means
but the claws might be normally caused to approach one another by means of a
spring or springs and an arrangement of toggle levers might be employed to force
them apart in order to receive the watch or other article or the required adjustment
might be obtained by other suitable means such as a cam or cams.
This clamping device may be permanently affixed to a bracelet or other article
or it may be provided with means for removably attaching it thereto so as to be
casily applicable to existing bracelets or the like.
In conjunction with the device hereinbefore described a bracelet may be
provided with means for increasing or reducing the diameter thereof.
The device may be employed in connection with a bracelet or watch chain, a
brooch or other article of jewellery.

Improvements in or relating to Bracelets and other Articles of
Jewellery.
We JOHN COOPER SAUNDERS of the Firm of Saunders and Shepherd of
Bartletts Passage Buildings Holborn Circus in the City of London Manufacturing
Jeweller and HERMANN DREWS of Pforzheim in the Grand Duchy of Baden
Germany Manufacturing Jeweller 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:--
The invention relates to means for facilitating the attachment of watches or
other articles to bracelets watch chains or other articles of jewellery.

page_text: adjustment and these base plates or frames & are guided in their movements by
means of an ornamental shield 6º.
The base plates or frames are formed with holes therethrough tapped with
right and left handed screw threads so as to constitute nuts adapted to receive
right and left hand screws formed upon a spindle 63 mounted in a central bearing 66*
carried by the bar and adapted to be turned by means of a watch key fitting
a square thereon the opposite end of the screw spindle working in a second
bearing carried by the ornamental shield 6*.
Or in lieu of the square 63 and watch key a milled button or other device might
be substituted for the square to enable the spindle 6 to be turned.
In order to place a watch in position within the clamp or holder the screw
spindle is turned by means of a watch key or otherwise until the base plates or
frames are caused to recede from each other in the manner indicated at Figure 3
when the watch is placed within the claws and a reverse movement is given to the
screw spindle thus causing the claws to approach the watch until it is firmly
clamped therein in the manner indicated at Figures 1 and 2.
In the example given at Figures 5, 6, and 7 the claws 6 in lieu of being hinged
or pinjointed to the frames or base plates are fixed thereto or formed thereon
and the frames or base plates & are pinjointed at b* to two pairs of toggle levers b³
all of which are pinjointed together and two of which are formed with returned
ends between which is arranged a spring which constantly exerts a force to
separate the returned ends and thus through the toggle levers to cause the
two pairs of claws to approach one another and clamp the watch in position
whilst the claws may be separated in order to receive the watch by pressing inward
the returned ends as will be readily understood.
In the example given at Figure 8 the claws bare fixed to or formed on the
frames or base plates 6' which latter are formed to slide upon the bar 65 by which
they are guided and the frames or base plates & upon their inner faces are bevelled
or inclined whilst a wedge shaped cam 12 is employed to separate the claws in order
to receive a watch and a spring to draw them together in order to clamp the
watch in position the cam being held in place and guided in its movements by
means of a headed screw 68 passing through a slot 6** therein and an extension **
passing through a fixed guide or loop * carried by the shield 6.
In the example given at Figures 9, 10 and 11 the device is somewhat similar to
that represented at Figures 1 to 4 with the exception that in this case it is adapted
to be affixed to an existing bracelet or the like.
For this purpose the bar and the shield jointly carry bearings in which
are mounted with capability of revolution screw spindles 6 formed with right and
left handed screw. threads working in corresponding nuts 10 which carry claws 6"
the spindles being provided with squares 6" similar to that of the screw spindle b²
or with other means of rotation.
By the arrangement of parts lastly herein before described it is only necessary to
insert the bracelet or the like between the claws in the manner represented at
Figures 10 and 11 and to cause the claws to approach each other by means of the
screw spindle & when the clamp or holder will be firmly attached to any existing
bracelet, watch chain, or other like article.
In the example given at Figures 12, 13, and 14 the device is similar in
construction to that represented at Figures 1 to 4 but in this case provision is made
for increasing or reducing the diameter of the bracelet to which the device is
affixed or rather increasing or reducing the space between the ends of the bracelet
according to the dimensions of the watch to be attached thereto.
According to this arrangement in lieu of employing a single bar & such bar is
divided into two parts ** mounted with capability of sliding in a guide or
bearing carried by the central bearing for the screw spindle 2 a binding
screw being employed to fix the two parts *** of the bar with relation to
each other after the required spacing has been effected.
Although the device hereinbefore described is shown in connection with a

page_text: bracelet as a holder for a watch it will be understood that it may be usefully
attached to a watch chain brooch or other article of jewellery and may be employed
as a holder for a locket a stone or other article so that the wearer may frequently
change the article to be displayed.
"
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In combination with a bracelet or other article of jewellery a clamp or holder
adapted to receive a watch or other article and provided with means of adjusting
the same to the diameter thereof substantially as herein shown and described.
2. An article of jewellery consisting of a clamp or holder adapted to receive a
watch or other article and provided with means of adjusting the same to the
diameter thereof substantially as herein shown and described.
3. An article of jewellery consisting of a clamp or holder provided with several
moveable claws and right and left handed screws engaging nuts connected with the
claws for causing the same to advance and retire substantially as herein shown and
described.
4. An attachment to an article of jewellery consisting of a clamp or holder
adapted to receive a watch or other article and provided with means of adjusting
the same to the diameter thereof and with means of attachment to an existing
article of jewellery substantially as herein shown and described.
5. In combination with a bracelet a clamp or holder adapted to receive a watch
or other article and provided with means for adjusting the same to the diameter
thereof and means for varying the distance between the ends of the bracelet
substantially as herein shown and described.
