AN IMPROVED CONSTRUCTION OR ARRANGEMENT OF BARS OR CHAINS OF SLEEVE LINKS AND IN THE METHOD OF ATTACHING THE FRONT OR FACE PLATES THERETO

page_text: I EBENEZER DOBELL of Robertson Street, Hastings, Sussex, Jeweller do hereby
declare the nature of my said invention for "AN IMPROVED CONSTRUCTION OR
ARRANGEMENT OF BARS OR CHAINS OF SLEEVE LINKS AND IN THE METHOD OF
ATTACHING THE FRONT OR FACE PLATES THERETO" to be as follows:-
The object of this invention is to so arrange the bar or chain of a sleevo link that
the face plate can be detached by a simple quarter turn or be locked in position by
pressing the stem into and between a pair of spring like plates which form part of
the bar.
For the purpose of my invention I split one half strap of the connecting bar
lengthwise and arrange the free ends between the base of an eyelet and of the other
balf strap to which the base of the eyelet is attached at portions of its circumference.
The other half strap of the connecting bar has a circular opening corresponding to
the opening in the eyelet and the stem of the detachable face plate which is flat
has a projection or shoulder on each of its two sides but none on its two edges.
The stem when pushed into the mouth of the eyelet to form the attachment
forces the spring plates apart and then closes over the two shoulders to fix it but
to detach the front plate, it has to be turned a quarter round which opens the
spring plates and allows the face or front plate to be withdrawn.
Dated this 30th day of August 1884.

page_text: I EBENEZER DOBELL of Robertson Street, Hastings, Sussex, Jeweller do hereby
declare the nature of my said invention for "AN IMPROVED CONSTRUCTION OR
ARRANGEMENT OF BARS OR CHAINS OF SLEEVE LINKS AND IN THE METHOD OF
ATTACHING THE FRONT OR FACE PLATES THERETO and in what manner the
same is to be performed to be particularly described and ascertained in and
by the following statement:-
"
The object of this invention is to so arrange the bar or chain of a sleeve link that
the face plate can be detached by a simple quarter turn or be locked in position by
pressing the stem through an eyelet and into between a pair of spring like plates
which form the bar or part of the bar.
For the purpose of my invention I split one half of a strap forming the connecting
bar of a sleeve link lengthwise and I arrange the free ends within or between the
base of an eyelet and of the other half strap to which the base of the eyelet is
attached at portions of its circumference. The other half strap of the connecting
bar has a circular opening corresponding to the opening in the eyelet and the stem
of the detachable face plate which is flat, has a projection or shoulder on each of its
two sides but none on its two edges.
The stem when pushed into the mouth of the eyelet to form the attachment
forces the spring plate apart and then closes under the two shoulders to fix it but
to detach the front plate it has to be turned a quarter round which opens the
spring plates and allows the face or front plate to be withdrawn.
My invention is clearly shown in the annexed drawings Figure 1 of which is an
elevation of a pair of sleeve links with one of the face plates detached. Figure 2 is
a perspective view also detached and Figure 3 a similar view with the face plates
connected.
ab
A is a bar forming the connection between the two face plates B. C. This bar is
attached to one of the face plates C and is, so to speak, composed of two pieces, one
of them D being split longitudinally for the whole of its length as shown at
Figures 1 and 4 and with its free ends E, F, partially within slots of an eyelet G
carried by the bar A in the central opening of which eyelet they project and are of
circular or curved shape on their inner edges.
The other face plate B has a flat sided stem H with the end somewhat enlarged
so as to form two angled surfaces shoulders I J with square undercut surfaces as
seen at Figure 2 into which the two ends E, F, of the split portion of the bar D
engage by their own springy action after being forced apart by the insertion of the
angled shoulders I J between them to form the attachment as at Figure 3.
Figures 5, 6 and 7 are views of a modified arrangement of the foregoing. In this
modification the bar A is dispensed with, the eyelet G being carried by the two
ends E, F, of the split bar D which ends are shaped to fit the holes in the eyelet G
and yet slide in them without becoming dislodged when the angled surfaces of the
stem H opens them out for the attachment to be made.
Instead of splitting the bar D it may be formed by bending a strip of metal as
at Figure 8 in which the bend serves as the attachment for the face plate C and
the two ends E, F, for supporting the eyelet G as last mentioned and also for the
connection of the other face plate B.
I have hitherto referred to one face plate only as having angled surfaces and
shoulders at the end of the stem H but both the face plates may be thus provided
in which case the bar D would be split at both ends and have eyelets as at Figure 9.
This would allow of different shape or patterns of face plates (in pairs) to be used

page_text: with the same double eyeleted split bar. Figure 10 shows the eyelet G when
moved into a line with the bar D the eyelet G being movable freely to any angle
for convenience in placing the link in the sleeve or wristband.
The connection of the face plate to the bar is effected by simply pushing the
stem into the eyelet, the ends of the bar opening out under the pressure and then
closing again to grip over the shoulders where they lodge themselves until the face
plate is turned a quarter round to the right or to the left, which motion not only
opens the ends of the bar but brings the plain edges of the stem into position for
easy withdrawal from the eyelet.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The bar D with springy ends E, F, projecting into an eyelet G to engage in the
shoulders of a stem H when pushed in for the attachment of a sleeve link face
plate thereto the said stem being released by a quarter turn motion as described
with reference to. the annexed drawings.
