HENRY ALEXANDER LYMAN of Old Bailey in the City of London Manufacturer
"IMPROVEMENTS IN BUSK AND OTHER FASTENINGS." [communicated to him from.
abroad by William Alfred Nettleton of Bridgeport in the State of Connecticut
United States of America]
The chief object of this invention is to provide for corsets a fastening which will
not open by the flexure of the body as is now not infrequently the case with
busk fastenings consisting of a headed stud attached to one steel entering an
elongated metal eye attached to the other steel of the busk fastening.
In attaining the object of this invention I use a headed stud as heretofore, and
also an elongated metal eye to receive it, but underlying the plate in which this
elongated eye is formed is a second plate also formed with an elongated eye, but
cut through at its end to give it lateral elasticity. The eye opening is also con-
tracted near its end to form an obstruction to the stud, which obstruction will
however yield to pressure so as to allow the stud to pass it, and springing back
retain the stud as in a closed eyelet.
The two plates may be connected together by the rivets used to fasten them to
the steel, and the stud may be so formed as to stand flush with the outer plate, its
head being caught in that case by the edges of the slot in the inner plate.
Where it is found unobjectionable for the stud to project from the plate the slot
in that plate may be contracted near its outer end to underlie the head of
the stud.

page_text: In that case the inner plate will be formed at its open end so as to grip the stem
of the stud, and thus prevent its working backwards into the enlarged part of the
slot of the outer plate and effecting its disengagement therefrom.
Instead of rivetting the fastenings to the steel strips, they may be secured
thereto by overlapping the edges of the strips as hitherto. In that case the inner
and outer plates must be rivetted together before applying them to the steel.strip.
The pieces for turning. over the edges of the strip will be obtained, the one by
giving the outer plate an extra length for turning over, and the other by turning
up a portion of the piece punched out of the plate to form the elongated eye.
Snap fastenings of this kind may be also applied to the securing of dressing bags
and similar articles

HENRY ALEXANDER LYMAN of Old Bailey in the City of London Manufacturer
IMPROVEMENTS IN BUSK AND OTHER FASTENINGS a communication to me from
abroad by William Alfred Nettleton of Bridgeport in the State of Connecticut,
United States of America
The chief object of this Invention is to provide for corsets a fastening which
will not open by the flexure of the body as is now not unfrequently the case with
busk fastenings consisting of a headed stud attached to one steel entering an
elongated metal eye attached to the other steel of the busk fastening
In attaining the object of this Invention I use a headed stud as heretofore, and
also an elongated metal eye to receive it but underlying the plate in which this
elongated eye is formed is a second plate.also formed with an elongated eye but
cut through at its end to give it lateral elasticity and constitute it a snap plate.
By the application of pressure the stud may be passed along the extended eyelet
of the plate until it has cleared it when the yielding plate springing back will serve
to retain the stud as in a closed eyelet.
In the accompanying drawing Fig: 1 is a front view of a steel busk with the
improved fastening applied thereto at top and bottom, the intermediate fastenings
being of the ordinary construction. Fig: 2 shews in inverted plan view and on
an enlarged scale the eyelet portion of the fastening secured by rivets to the busk;
Fig: 3 is a longitudinal section of the saine taken at the line 1. 2 of Fig: 2, and
Figures 4 shew, detached, the two plates which constitute the eyelet portion of the
fastening.
.
A and B are the two steel strips which form the busk. To the steel A are
rivetted studs a of the ordinary form which are intended to enter the eyelets
carried by the strip B. The top and bottom fastenings only are of the new con-
struction, the intermediate ones which are made in the usual manner having no
tendency to unfasten through the flexure of the body when used in conjunction
with the improved fastening.
b is a plate formed with an elongated eyelet, and underlying this plate is a
shorter plate c formed with an eyelet that corresponds with that in the plate b which
eyelet is also elongated and to the full length of the contracted plate. Between
the end of the extension of the slot in the plate b and the extremity of the plate c
there is sufficient space as shewn in the section Fig. 3 for the neck of the stud a to
rest in. I have said that the slot in the plate c is elongated but its width is
somewhat less than the elongation in the plate b.
When therefore the head of the stud is passed through the plates b and c and
the stud is then drawn towards the end of the fastening the plate c will yield to
the pressure of the stud and allow it to pass through its slot to the position of
Fig. 3.
On the stud getting clear of the plate c the yielding plate c will snap behind it
and its end will serve as a stop to the stud, and prevent its working back to the
eyelet and so effecting the disengagement of the fastening. The outer ends of the
edges of the slot of the plate care, however, rounded off to permit of the stud
moving backwards when the busk is intended to be unfastened; the pressure put
upon the fastening for this purpose will compel the snap plate c to yield laterally
and permit of this movement of the stud.
It will be understood however that no mere flexure of the busk can put upon
the fastening the requisite pressure for ensuring the disengagement of the stud.

page_text: Fig: 5 shews in front view the improved fastening secured to the steel without
revetting and Fig: 6 shews the mode in which this fastening is effected. Fig: 7
shews the form which the plate b takes to provide a clip for attaching it to the
busk
In this case the inner and outer plates bc must be rivetted together before
applying them to the steel strip
-
The pieces for turning over the edges of the strip it will be seen are obtained,
the one by giving the outer plate b an extra length for turning over, and the other
by turning up a portion of the piece punched out of the plate to form the
elongated eye..
In some cases it will be desirable to make the stud head when in place stand
flush with the outer plate
The manner in which this is effected is shewn at Figures 8. 9 and 10, Fig: 8
being a front view of the fastening Fig: 9. a section taken in the line 3. 4 of Fig: 8,
and Figures 10 being detached views of the eyelet plates b and c. In this example
it will be seen that the elongated eye of the plate bis of the same breadth
throughout, whereas in the underlying snap plate c. the extension of the eyelet is
contracted in breadth, its length is however equal to that of the plate b. Thus a
support is formed below the plate 6 for the head of the stud a to rest on; and the
head of the stud being of the same thickness as the plate b it will stand practically
flush with it. The under plate c, is slit as before to allow of its yielding to the
pressure of the stem of the stud a, and in the slot, slight projections or shoulders are
formed for the purpose of presenting an obstruction to the stud which obstruction
will however yield (owing to the slit in the plate) to direct pressure from the stud
stem, and snapping in rear of the stud as it passes to the end of the slot will retain
it in the fastened position.
Snap fastenings of this kind may be also applied to the securing of dressing bags
and similar articles.
Having now set forth the nature of the Invention of "Improvements-in-Busk
and other fastenings" as communicated to me from abroad and explained the
manner of carrying the same into effect I wish it to be understood that under the
above in part recited Letters Patent I claim
Firstly The application to busk and other fastenings of a snap plate acting in
the manner and for the purpose above explained with reference to the accompanying
drawing :
Secondly The arrangement above described with reference to Figures 8. 9 and 10
for providing a snap fastening with a flush stud head.:
In witness whereof I the said Henry Alexander Lyman have hereunto set my
hand and seal the Second day, of January in the year of our Lord One thousand
eight hundred and eighty four.
