There were two versions of the Earl, the 778 and the 777, the difference between the two were the number of coils on the springs. The less coils the weaker the door spring (lighter doors) the more coils the stronger the door spring (heavier doors). The Earl 778 was the more powerful of the two versions.
Stanmore Springs Ltd were continually improving their product, beginning with the Coronet and ending with the Earl. In its final guise as the Earl this floor spring could be adjusted both from side to side and front to back by means of a capstan. This capstan was threaded directly into the cast case and pressed upon the inner surface of the box that was concreted into the ground. There were two versions of the Earl, the 778 and the 777, the difference between the two were the number of coils on the springs. The less coils the weaker the door spring (lighter doors) the more coils the stronger the door spring (heavier doors). The Earl 778 was the more powerful of the two versions. The improvements that culminated in the Earl are attributed to Robert Douglas Derek Smith of Stanmore springs Ltd. The final patent was granted on the 21st of July 1971.

I remember when I was in my 30's working at W & R Leggott(Ironmongers) of Peckover Street.Bradford. I had happy days there working in the iron dept and my job was repairing the Leggott's 'Girda' fllorspring s and other models plus the Stanmore springs as above.I also sometimes had to go to Stanmore Spring company in Leeds to obtain spare parts. I,my brother and father(Engineer Designer)had happy times.

AuthorAs 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. Archives
