Abstract

26,672. Snowball, J. L. Nov. 17. Latches, lift and thumb.-The jamming &c. of a liftlatch when a door slams is prevented by forming a slot D in the end of the latch A and mounting above it a casing B containing a loose disk C. This disk is bevelled on the inward side, and rises over and drops behind the striking - plate E, thus securing the latch, which can, however, be released by the usual thumb-piece.
