    Default Seeking information on a mortise lock removed from a 1930's home

    Can someone please help me identify the maker of the mortise lockset and how to repair it?

    A relative removed a mortise lockset from an entry door from a 1930's era house because the knob was difficult to turn. So, he removed the lockset from the door and opened the metal casing. As he was handling the mechanisms of the lockset the flat spring snapped. The flat spring was positioned on its edge on the bottom of the casing below the stop works buttons. The flat spring is 3 inches long and 1/4 inch wide. Where do I find a flat spring replacement? Also, the relative thinks the other or odd shaped flat spring was located under the longer stop works button. However, when he placed the spring where he thought he found it, the casing cover no longer fit snugly with the bottom casing. So, my other question is where does that odd shaped flat spring fit in the casing? and who is the maker of the lockset? Penn is engraved near the keyhole. However, that keyhole may have replaced an original skeleton keyhole. Thanks for your help.

    Looking at your pictures, the odd shaped spring should be placed with the loop around the post under the steel part and compressed between the two buttons. The longer of the free ends should be against the longer button.


    A replacement for the broken spring might be available from a (proper) locksmith or could be made from a part of an old clock spring or an old automotive feeler guage of suitable thickness.


    As for identification, I am sure someone here will know.
