Abstract
Abstract A door latch for storm and screen doors having pre-drilled bolt receiving openings therein by which the latch housing are secured to opposite sides of the door. One of the latch housings has a plurality of openings therein and the other housing has a pair of inserts each having an inwardly extending internally threaded mounting post adjacent one end thereof and projecting through one of the openings in the door for receiving a threaded bolt inserted through an aligned opening in the other housing. The inserts are reversible end-for-end to vary the spacing between the mounting posts thereby to adapt the latch for use on doors having differently spaced bolt openings therein.

Claim 1
Independent Claim
179 words
A door latch for storm and screen doors having a pair of pre-drilled bolt receiving openings therein by means of which the latch is secured to the door; comprising a pair of latch housings adapted to be mounted on opposite sides of the door, an operating handle carried by each housing and latch mechanism cooperatively associated with and operable by said handles, one of said housings having a plurality of openings therein, the other of said housings having a pair of inserts each having an outer portion seated in a correspondingly shaped recess in said other housing and an inwardly extending internally threaded mounting post, said mounting posts being insertable through said openings in said door for receiving bolts insertable through aligned openings in said one housing, each insert being reversible end-for-end within its recess and having its mounting post located nearer to one end thereof than the other so that end-for-end reversal of said inserts will vary the spacing between said mounting posts thereby to adapt said latch for use on doors having differently spaced bolt openings therein.
Claim 2
Dependent Claim
179 words
A door latch for storm and screen doors having a pair of pre-drilled bolt receiving openings therein by means of which the latch is secured to the door; comprising a pair of latch housings adapted to be mounted on opposite sides of the door, an operating handle carried by each housing and latch mechanism cooperatively associated with and operable by said handles, one of said housings having a plurality of openings therein, the other of said housings having a pair of inserts each having an outer portion seated in a correspondingly shaped recess in said other housing and an inwardly extending internally threaded mounting post, said mounting posts being insertable through said openings in said door for receiving bolts insertable through aligned openings in said one housing, each insert being reversible end-for-end within its recess and having its mounting post located nearer to one end thereof than the other so that end-for-end reversal of said inserts will vary the spacing between said mounting posts thereby to adapt said latch for use on doors having differently spaced bolt openings therein.
Claim 3
Dependent Claim
