ALEXANDER JOHN FRASER, of Holloway, in the County of Middlesex. "Iм-
PROVEMENTS IN FASTENINGS FOR BRACELETS, NECKLETS, PURSES, BAGS, AND SIMILAR
ARTICLES, ALSO APPLICABLE TO OTHER PURPOSES."
My improved fastening consists of a cylindrical box or case, in the centre of the
bottom of which I fix a stud, having on its upper end a tag or key. Inside the said
box or case I place another case, in the bottom of which I drill a hole of a size to
allow the herein-before described stud with its key to pass freely through; a thin
disc of metal is fitted inside this inner case with a hole in the centre to fit the stud,
having also a slot on one side to admit of the key passing through, and a thin ring
is affixed to the upper edge of this inner case to keep the disc in its place, and on
the upper surface of this disc is a slight projection to admit of its being rotated.
When the smaller is placed within the outer case, and the disc is moved into any
position other than that in which the key is opposite its corresponding slot, the
inner case will be securely locked to the outer case.
For bracelets or necklets I affix a lug to project from the side of the outer case
at the bottom, having suitable perforations to admit one end of the bracelet being
fixed thereto. I make a slot in the outer case exactly opposite to this lug, and at
the bottom of the inner case I make a similar lug fitted to pass down the slot in the
outer case.
When intended to be applied to travelling bags, instead of the herein-before
described lugs I make the bottom of the outer case larger than the diameter of the
case itself, thus leaving a flange or margin all round; in this flange are certain holes;
I punch a hole in one jaw of the bag frame to admit the outer case which is to be
rivetted to the frame, and the other jaw is treated in the same manner so as to
carry the inner case, which has a flange on its upper edge; the locking arrangement
is the same as for the bracelet snap.
Instead of having the head of the stud in the outer case to project through the
rotating disc on the inner case, I sometimes form a stud much shorter, making the
perforation in the bottom of the inner case and that in the rotating disc in

page_text: the same manner as already described for the other arrangement, the only difference
being that on the upper side of the rotating disc I fix a second disc with a circular
perforation large enough to take in the stud with its tag; and on this disc I place a
plain disc without perforation, which completely screens the stud from view when
the inner case is put into its place..
My Invention can be used as a bolt on violin or other cases with a falling lid,
also for fastening the ends of driving bands for machinery, and for other purposes
requiring the junction of two ends, in such a manner that they cannot easily come
asunder, except when the rotating disc is turned in the manner herein-before
described.
