COMPLETE SPECIFICATION.
Improvements in or connected with Corset Joints.
We, NATHEN COHEN, Picture Frame Maker and ABRAHAM DAVIS, Turner, both of
21 Duke Street in the City and County of Newcastle-on-Tyne 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:―
Our invention refers to improvements in or connected with corset joints and has
for its object to facilitate the undoing or unfastening of the corset when the wearer
wishes to take this article of apparel off, and at the same time avoid any necessity
for the wearer to assume any contracted or other unnatural position in order to cause
the hooks or eyes or other connections with which the corset may be jointed to come
apart or separate.
We will now describe how we accomplish our object with reference to the accom-
panying drawings in which
Fig. 1 shows a front view or elevation of our apparatus with the mechanism in the
open or unlocked or disjointed position.
Fig. 2 is a similar view showing the apparatus in the shut or locked or jointed
position and
Fig. 3 is an end view or elevation of the left half portion of Fig. 2 with plate a
and hooks c removed.
Referring to the drawings, a is a thin steel band forming one margin of the
corset which is intended to be jointed to or disjointed from the opposite margin of
the corset. This latter margin we form with two thin steel bands b and c which are
connected together by rivets d and slots d'in such a manner that by the mechanism
hereinafter described one of the plates can slide up and down to the required extent
upon the other. This mechanism consists essentially of a plate d of a somewhat
peculiar shape shown centred or pivotted on the uppermost pin or rivet d which is
secured to the back plate c of the plates d and c. The uppermost slot d' in plate b
allows the latter to move up and down on plate c. In the plate d is a path or
groove d³ eccentric to the axis on which the plate works and on the plate bis fixed a
pin d arranged to work or travel in the groove d³ aforesaid. On a projection of the
plate 2 is a knob d³ to act as a lever or handle for actuating the mechanism. The
back plate c has slots or recesses c¹ cut out of its edge at sufficient intervals into which
the hooks on plate a are designed to fit. The hooks may be rivetted to plate a and
have each a spring tongue raised out of the hook plate which presses against the
under lip of the hook and thus acts as a lock thereto. The plate has slots or
recesses cut out of its edge to correspond with the slots c aforesaid and out of
these slots additional slots 62 are cut in order to form the teeth which as herein-
after described engage with the eyes or lips formed on the hooks c².
The operation of our invention is as follows:
When the plate d is pulled round by its knob from the position shown in Fig. 2
o the position shown in Fig. 1 the pin d working in groove d³ is drawn upwards
lue to the disposition of the groove and the centre of motion of the plate and as dis
ttached to plate & the latter is caused to slide upwards on the plate and this
pward motion caused by the simple turning of plate d simultaneously withdrawing
the teeth on plate 6 from the hooks e, the corset is instantly unfastened. On
utting it on again the teeth 63 way first be lowered into the po ition shown in Fig. 2
hen the hooks can be hooked onto the teeth in the ordinary way.
The bands u be are sufficiently flexible to conform to the ontline of the wearer
nd the travel of the band & for regulating the locking and unlocking of the teeth b³
ay be varied by varying the axis of the groove da relatively to the centre of motion
the plate d².

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is :
1. For unfastening corsets the use of a pair of plates arranged so that one of
them may slide upon the other and thus open or shut the hook slots or openings by
means of a power plate having a groove therein eccentric to the centre of motion of
the power plate aforesaid, actuating a pin attached to the moving plate substantially
as herein described and illustrated in the accompanying drawings.
2. The combination of parts consisting of the plates bc with slots d' and pins d,
grooves c¹¹², teeth ³ and plate d³ with groove d³ and pin d all arranged, disposed
and working substantially as and for the purposes herein before described and
illustrated in the accompanying drawings.
3. The arrangement or combination of parts constituting the improvements in
corset joints substantially as herein set forth.*
