Eveline van Breemen from the North Lincolnshire Museum Service Would like to confirm (or deny) that the item in the attached photographs is a floor board cramp. She is concerned that it may have been misclassified.

Yes, it's definitely a floor cramp. The prongs go either side of a joist, the pad goes against the edge of the nearly-last board and the screw presses the boards tight together ready for nailing.

It's included in several catalogues from the early 20th century. This image from the 1908 Tyzack catalogue identifies it as "Kimberley Pattern" - that may well be the name just visible on the top in the first photo.
