Improvement in Slip Hooks.
We HENRY STANNING of 25 Charles Street Walworth in the County of Surrey,
Army Belt Maker, and FRANK SALES PERKINS of 220 Penton Place Walworth,

This invention relates to improvement in slip hooks, the idea of which is to
instantily release the object, with which it is attached, without the usual methord of
slackening, the weight or pull on the hook.
This hook is made with an hinged tongue and is fastened by an hinged loop,
which acts on a flat spring, keeping the tongue in position when fastened, and the
act of pulling the hinged loop back, the tongue flys out of position, releasing
the object which is attached thereto, and in closing the tongue in position, the
corner spurs forming part of the hinged loop, comes in contact with the point of the
hinged tongue fastening same.
