1889? Hand Cranked Permutation Door Lock Workings
Hand Cranked Permutation Door Lock
I think this is a lock made from the 1889 C.F. Bilhimer patent located here http://www.google.com/patents?id=GkZ...ed_pages&cad=1 I am still trying to track down the manufacturer and the date of this model but I think that through the patent information I have it traced back to Irwin Pennsylvania after 1889. The lock is still in the condition I found it except for a bit of white grease I sprayed into it to help it turn.
I have been asked to post the inner working of this lock here. The complete photos can be found at http://www.kingscience.info/LockDis.htm
