Making a spring for an American R&E Co Rim Lock
Well another day and another interesting job. Making a spring for an American Rim Lock made from cast iron by Russell & Erwin Company with patent from the 1860s. How did an American lock make its way to Australia? More questions for my client I suppose.Post and Bar method of twisting wire into a spring. |
Opening the case of the lock I found a broken spring that needed to be remade. I used a post around the same diameter as the pivot point and a bar with a hole the same gauge as the wire to make a new spring. I clamped the wire and post in the vice, threaded the wire through the bar and twisted the wire around the post.
Interesting feature of a privacy snib which locks the latch in place to lock out the handle to prevent someone outside from opening the lock with a key. More soon when the keys come in from Tasmania.
