latest find - Chamberlain 1849
« on: September 15, 2019, 05:16:35 PM »
My oldest wrench find to date.  Marked D.H. CHAMBERLAIN, PATENT 1849.  This was Patent #6210, Mar 20, 1849, Boston, MA.  15"L.  Missing some sort of handle.  With the screw in lower position, you can slide the jaw open/close.  Anyone have one of these.  Wondering if my adjustment screw is original, and if the handle would have been wood or metal.

Handle is steel, the thing that has me confused is the threads shouldn't be showing like they are in your picture. Mine is like the patent drawing. There is a UK spanner that is very similar but I never found a link between the 2 wrenches.

Twist the handle to open & close the wrench jaws.

Palmer & Sons is the UK spanner that is close in design.

Between 1835 and 1854 Dexter Chamberlain was issued 10 patents but only 2 were wrenches.
