Improvements in Watch Protector Swivels.
I, WILLIAM THOMPSON BRAHAM of 392, Stretford Road, Manchester in the
County of Lancaster, Watchmaker, do hereby declare the nature of this invention
to be as follows:-
A swivel of any suitable metal, the upper part of which is similar in construction
to an ordinary watch swivel, therefore that part of my invention need not be further
described, the lower part of said swivel has two hooks with one or more prongs or
sharp points, the said hooks are placed together, with the prongs extending in
opposite directions, the other ends of aforesaid hooks are pierced and rivetted to
the herein before-mentioned swivel, the coiled spring of which presses upon the tops
of the jointed hooks-which are slightly flattened—or shaped in such manner as to
keep the hooks in position. When the chain or guard to which the "Watch
Protector Swivel" is attached receives a pull the prongs fly outward.
