After the Christmas holidays the first floor springs we had to deal with were 5 Britannic's at Nottingham University's Law and Social Sciences Building. Some we swapped outright from our stock and some we repaired as can be seen below in the pictures. There were a number of problems we had to overcome including broken springs, wear to the claws, broken piston wheels and wear to the pivots.
The wear has been dealt with, time to put the Britannic's back together again.
Below are comparative shots showing the evolution of the Britannic (William Newman and Sons) also known as the Leader when supplied by Parker Winder & Achurch or the Lion when supplied by Yannedis & Co Ltd.
August 26th, 1926 Herbert George Newman of William Newman & Sons Patent of the Britannic.
William Henry Tonks along with Walter Sparks was also responsible for a similar design dated September 4th, 1924.
Further improvements were also attributed to Tonks of what appears to be an amalgamation of the two designs dated January 21st, 1932.
Comments are always appreciated.
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.
