"The Wallace" Edwin Showell and Son

I have mentioned The Wallace previously, manufactured by Edwin Showell & Sons (another Birmingham based door spring manufacturer) so this will just be a quick post. The owner of The Wallace had a problem with it, when the door it was connected to was opened 90 degrees, no problem but when the door was only opened 15 to 20 degrees and let go, it slammed (although it didnt if the door was held for 30 seconds or so). This was obviously a concern to our customer so he brought it to us for investigation after having taken it to a couple of other places and had a go at modifying the piston himself.

After some investigation it was noted the piston and oil intake were in our opinion manufactured in such away it was never designed to have control if the door was only opened a little way.

We therefore changed the configuration, designing a bespoke one way valve, manufacturing it and used it in conjunction with the original system. You can see the valve was incorporated into the head of a "manufactured" bolt in the picture, this was not the first design, we were going to place a new valve into the piston itself but this was decided against for a number of reasons.

The Wallace now has control from 1 degree, through and up to 90 degrees instantly.

    As there is so little information out there with regard to door closers, especially vintage and antique model floor springs, I thought I would start this blog.
