Climax (For Internal Doors)

I have covered the Climax a number of times in this blog however here is a Climax I have recently come across that is different to the ones I have previously mentioned.

The main differences are the size and the spring configuration. In this version of the Climax the springs are compressed as opposed to expanded as they are in the previous blog posts regarding the Climax.

A little heat was required to loosen these stubborn machine screws. They are quarter Whitworth if you were wondering, here is a link to the story behind the Whitworth thread.

And a link to the story of Joseph Whitworth.

As can be seen there is extensive wear to the wheel on the pin that transfers the left/right motion of the door to the up/down motion that compresses the springs.

This was filled with weld and then reground.

As can be seen in the above comparative shots this Climax is smaller than the one used for external doors.
