COMPLETE SPECIFICATION.
An Improved Fastening for Bracelets, Cuffs, and other articles.
I, GEORGE ERNEST LANCELOTT, of 49, Tenby Street North, in the City of
Birmingham, Diesinker and Tool Maker, 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 :-
This invention consists of the improved fastening herein described for bracelets,
bangles, neckletts, cuffs and other articles of dress and for other uses. The said
fastening resembles a self locking padlock but instead of the bolt or catch being
operated by a key to release the shackle, the bolt or catch, according to this
invention is continued through one side of the padlock so as to form a pusher, or
there may be a separate pusher projecting through one side of the padlock and
arranged to act upon the bolt so that by pressing the pusher the shackle is released
from the bolt or catch and the padlock or fastening can be opened.
On the accompanying drawing
Figs. 1 and 2 are sectional elevations of my improved fastening the shackle being
represented as unlocked in Fig. 1 and locked in Fig. 2;
Fig. 3 shews the bolt of the same separately and
Fig. 4 also shews the bolt before it is bent as hereinafter described;
Figs. 5 and 6 are sectional elevations of a modification of my invention and
Fig. 7 shews the bolt and pusher of the same separately;
Figs. 8 and 9 are similar views of a further modification;
Fig. 10 shews a further modification and
Figs. 11 and 12 shew a further inodification.
The same letters of reference indicate the same or corresponding parts in all the
figures.
Referring firstly more particularly to Figs. 1, 2 and 3 a is the case of the
fastening and b is the shackle which at one end is jointed to the case at c and the
other end is pointed or inclined so as to force back the spring bolt or spring
catch d when locking the fastening. At a short distance from the end 6' of the
shackle there is a notch e into which the bolt or catch d engages to lock the
shackle. So far this construction of the fastening is similar to some well known
kinds of padlocks. In order to lock the shackle I provide the sliding bolt
(shewn separately in Figs. 3 and 4) one end d¹ of which projects through the side
of the padlock case and forms a pusher. At the other end of the bolt d there is a
spring which acts upon the bolt d and maintains the end d' of the bolt projecting
through the case. The end d² of the bolt is bent down to engage with the bar a¹
of the case (between which bar and the top of the case the bolt d is free to slide)
and thus prevent the bolt moving too far forward. The bolt d is recessed at d³
to engage in the notch e in the shackle b.
When the shackle bis closed into the lock case as shewn in Fig. 2 the inclinedl
end of the shackle first acts upon the recess d' and forces the bolt d back
against the spring and then as the movement of the shackle is continued the
spring forces the bolt forward again into the notch e and thus secures the
shackle. To open the shackle the pusher end d' of the bolt has first to be
pushed inwardly so as to free the bolt from the notch e when the shackle will be
free to be opened.
When the parts of the case are secured together by soldering as is the case when
the fastening is made as an article of jewellery the parts of the case are first
soldered together, then the bolt d which is made straight as shown in Fig. 4 is
inserted into position through the hole in the side of the fastening and the end ²
is by a tool inserted through the opening bent down to form the stop and

page_text: through this opening the spring f is then inserted into position. The shackle is
then jointed to the case by the joint pin c.
In the modification of my invention shewn by Figs. 5 and 6 instead of the spring
bolt or spring catch d being arranged to slide to and fro in a straight line the
spring bolt or catch d is jointed at d to the casing a so as to turn about this
point d' as a centre when the acting end of the bolt or catch springs into or is
disengaged from the notch e and the part de forming the pusher projects through
the side of the padlock below the end of the shackle.
In the further modification shewn by Figs. 8 and 9 the spring f constitutes the
spring bolt or spring catch one end of the spring being hooked or bent so
as to engage with the notch e in the shackle when the latter is closed. By pushing
inwardly the pusher d' arranged in the side of the lock case a the spring can be
forced away from the notch e in the shackle so as to allow the latter to be opened
as shewn in Fig. 8. Or, as shewn in Fig. 10 instead of operating the spring bolt
or catch by a part such as d' which is pushed inwardly to release the spring
bolt or catch from the notch in the shackle the pusher d³ may be arranged to slide
along a slot in the case so that when the pusher is moved down towards the lower
end of the spring catch or spring bolt the latter will be disengaged from the
notch e in the shackle and when the pusher is moved in the opposite direction the
spring bolt or spring catch will be free to engage with the shackle. Or as
shewn in Figs. 11 and 12 the pusher may be jointed at de to the case a so that
when that end of the pusher which projects through the case is pushed so as to
turn the pusher about its centre d the other end of the pusher disengages the
spring bolt or spring catch from the notch e in the shackle.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In a fastening for bracelets cuffs and other articles and in combination with
the casing thereof (such as a) and the shackle thereof (such as 6) the employment
of a spring bolt or spring catch adapted to engage with the shackle and to be
released from the shackle by a pusher projecting through one side of the case of
the fastening substantially as herein before set forth.
2. The combination and arrangement of parts constituting the improved fastening
for bracelets cuffs and other articles herein before described and illustrated by
Figs. 1, 2, 3 and 4 of the accompanying drawing and the modifications thereof
hereinbefore described and illustrated by Figs. 5, 6 and 7; by Figs. 8 and 9 ;
by Fig. 10 and by Figs. 11 and 12.
