Working with Hands - James E. Price


 
  Transmission  for Accelerated Drilling - Patented Device 2 of 2  

For illustration purposes I chucked it in a Darling's Patent brace that was patented just 5 years before the transmission and is the one illustrated on the cover of Ron Pearson's book.

In fact, I got this brace from Ron who was a great pal of mine. He wrote the book on patented braces and I wrote the one on the patented tools that fit in them. B. Darling was issued a patent for this brace on October 20, 1868.

In this photo the transmission is chucked in a Darling's Patent brace.

Here is what it looks like in more detail.

Darling's Patent No. 83,261.
