PROVISIONAL SPECIFICATION.
Improvements in Fastenings for Corsets and other Articles.
I, CHARLES EUGENE POSTLETHWAITE, of No. 30, Cawley Road, South Hackney, in
the County of Middlesex, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
formed with
This invention relates to that class of fastenings in which one part thereof is
keyhole slot therein to receive a headed stud carried by the other
part thereof, and the invention has for its object to prevent the accidental disconnection
of the two parts.
For this purpose, one part of the fastening is provided with a locking device which
closes, or is capable of being closed upon or against the headed stud when it has taken
up its position in the contracted end of the keyhole slot.
The locking device consists of a bar, plate, hook, or stop hinged to the slotted
part of the fastening and capable of being turned into position to prevent the
headed stud leaving the contracted end of the keyhole slot, and the said bar,
plate, hook, or stop is, by preference, retained in its closed position by the action
of a spring.
Or the bar, plate, book, or stop may be carried by the other part of the fastening,
and may, when closed, embrace or cover the headed stud, or take an abutment against
the end of the slotted part of the fastening in order to lock the stud in the desired
position.

COMPLETE SPECIFICATION.
Improvements in Fastenings for Corsets and other Articles.
I, CHARLES EUGENE POSTLETHWAITE, of No. 30, Cawley Road, South Hackney,
in the County of Middlesex, 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:—
This invention relates to that class of fastenings in which one part thereof is
formed with a keyhole slot therein to receive a headed stud carried by the other part
thereof, and the invention has for its object to prevent the accidental disconnection of
the two parts.
For this purpose, one part of the fastening is provided with a locking device which
closes, or is capable of being closed upon or against the headed stud when it has taken
up its position in the contracted end of the keyhole slot.
The locking device consists of a bar, plate, hook, or stop hinged or pivoted
to the slotted part of the fastening, and capable of being turned into position to prevent
the headed stud leaving the contracted end of the keyhole slot, and the said bar,
plate, hook, or stop is, by preference retained in its closed position by the action
of a spring.
Or the bar, plate, hook, or stop may be carried by the other part of the fastening,
and may, when closed, embrace or cover the headed stud, or take an abutment against
the end of the slotted part of the fastening in order to lock the stud in the desired
position.
And in order that the said invention may be more clearly understood and readily
carried into effect, I will proceed, aided by the accompanying drawings more fully to
describe the same

page_text: according to my invention.
Figure 2. is a front view of a similar fastening representing a slight modification in
the method of mounting the locking device.
Figure 3. represents a front view and a transverse section of a modification in the
form of the locking device.
Figure 4. represents a front view and an edge view of a modified form of locking
device.
Figure 5. is a front view representing a similar but slightly modified form of locking
device.
Figure 6. represents a front view an edge view and a transverse section of a further
modification and
Figure 7. represents a front view and an edge view of a further modification.
In the several Figures, like parts are indicated by similar letters of reference.
Referring to Figure 1. a represents one part of the fastening which has rivetted
thereto a plate a² formed with a keyhole slot a¹ therein to receive a headed stud b
carried by the other part 6 of the fastening, as is well understood.
Upon the plate a² of the part a. of the fastening, is hinged or pivoted a bale or
locking device c. in such manner that it is capable of being closed or of closing with
its bar c¹ upon or against the headed stud 61 when the latter has taken up its position
in the contracted end of the keyhole slot a¹.
The bale or locking device c. is formed with projecting ends c³ or trunnions which
enter corresponding holes formed in lugs d¹ carried by a plate d and by reason of the
bale at that point bearing with a lateral pressure against the inclined edges of the
lugs d' of such plate the locking device c. is normally held in its closed position with
a spring pressure.
In the example given at Figure 2. the position of the locking device c. is reversed,
the shape of the bar c' being modified accordingly, but otherwise the parts are similar
to those hereinbefore described.
c¹
In the example given at Figure 3. the action of the locking device is similar to
that hereinbefore described, but, in this case, the device consists of a plate c. hinged
at d to the plate a² of the fastening and provided with spring clips c* to embrace the
plate a² and hold the locking device c. in position.
In the example given at Figure 4. the locking device consists of a plate c. hinged
at d to the edge of the plate a² and adapted to be turned into position to retain the
stud 6' in the contracted end of the slot a' and in order to hold the plate or locking
device c. in its locked position, spring clips a* are provided upon the opposite edge
of the plate a².
In the example given at Figure 5. the parts are similar to those lastly hereinbefore
described with the exception that in this case the locking device is formed with
an opening c therein to receive the head of the stud 6 of the part b. of the
fastening.
In the example given at Figure 6. the locking device consists of a plate or hook c.
mounted upon a pivot or hinge d¹ upon the plate a² and provided with a slot or
opening in the head thereof to receive the stud ₁ of the part b. of the fastening, a
spring a being employed to exert a frictional pressure upon the plate or hook c. and
thereby hold it in its locked position.
In the example given at Figure 7. a plate or locking device c. is hinged at d¹ to the
part b. of the fastening and is so arranged as to take an abutment against the end of
the slotted plate a² in order to prevent any movement of the parts and consequently
the withdrawal of the stud b¹ from the slot a¹ and the end of the locking plate c. is
recessed to receive the nose of the plate a² in order to prevent the opening of the
locking plate c.
I would here remark that I do not confine myself to the precise details of

page_text: construction hereinbefore shown and described as it is evident that the same
are capable of considerable modification without departing from the spirit of
my invention.
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. The improvements in fastenings for corsets and other articles substantially as
herein shown and described.
2. A fastening formed with a keyhole slot a¹ in one part thereof, a headed.
stud 6 fixed upon the other part thereof and a locking device c. for preventing
the parts becoming disconnected substantially as herein shown and described.
