Abstract
Abstract A door lock is assembled by mounting the fork bolt, the detents, and various links for the detents on a main frame to provide a latching mechanism subassembly capable of being tested. The outside and inside operating members, the intermittent member, and the locking lever are mounted on the auxiliary frame to provide an unlatching mechanism subassembly capable of being tested. Both subassemblies are tested and then assembled as a unit.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
206 words
A method of assembling a closure latch comprising, pivotally mounting a bolt on a main support frame for movement between latched and unlatched positions, pivotally mounting a primary detent on the main support frame for movement between holding and released positions with respect to the bolt, pivotally mounting a secondary detent on the main support frame for movement between holding and released positions with respect to the bolt, pivotally and slidably mounting a transfer link on the main support frame, and coupling the transfer links to the primary detent and to the secondary detent to provide a latching mechanism subassembly capable of being tested as a unit, pivotally mounting an operating lever on an auxiliary support frame for movement by inside and outside release means, pivotally mounting a locking lever on the auxiliary support frame for movement between locked and unlocked positions, pivotally connecting an intermittent member to the operating member, and pivotally and slidably connecting the intermittent member to the locking lever for movement between coupled and uncoupled positions with respect to the transfer link to provide an unlatching mechanism subassembly capable of being tested as a unit, testing the subassemblies, and assembling the main support frame and the auxiliary support frame to each other.

Claim 3
Independent Claim
175 words
A method of assembling a closure latch comprising, pivotally mounting a latch bolt on a main support frame for movement between latched and unlatched positions relative thereto, pivotally mounting a detent on the main support frame for movement between holding and released positions with respect to the bolt to provide a latching mechanism subassembly capable of being tested as a unit, pivotally mounting an operating lever on an auxiliary support frame for movement by inside and outside release means, pivotally mounting a locking lever on the auxiliary support frame for movement between locked and unlocked positions, operatively connecting an intermittent member to the operating lever, pivotally and slidably connecting the intermittent member to the locking lever for movement of the intermittent member between coupled and uncoupled positions to provide an unlatching mechanism subassembly capable of being tested as a unit, testing the subassemblies, and assembling the main support frame and the auxiliary support frame to each other to complete the assembly of the closure latch and locate the intermittent member with respect to the detent.
