The Climax is unusual as the springs within are configured to expand rather than contract as in most other models. There is an ingenious vertically positioned wheel connected to the pin that lifts a claw which in turn is coupled to one end of the 8 springs. This claw expands the springs and as they contract the action is reversed closing the door smoothly. As can be seen there is no hydraulic nor pneumatic check in this early model door closer.
I now have two late Victorian era fully refurbished floor springs awaiting a customer.
