Patent help England

Need some help from English patent wizard.
These pats are for the swivel wingnuts that hold together the clamps on a vintage tennis racquet.

Patent issued to Dale, Forty, and Company Limited in 1926

Wow!  These things are so complicated that it is no surprise that they were eventually replaced by simpler, and cheaper--though less elegant--wingnuts.

Here is the tie press application:  https://www.ebay.ie/itm/VIntage-Tie-press-Royal-Letters-patent/323776844414?hash=item4b629a927e:g:tmMAAOSwf6Fcl-Z1
