In a press, a piece of wood nailed across the wooden ribs on the under side, close to the winter, to keep them steady in their place.
In Moxon's time a summer was for a different purpose; viz. to prevent the cheeks of the press from springing open; the winter was dovetailed into the cheeks, to answer this purpose: after describing the winter, he adds:
“But yet I think it very convenient to have a Summer also, the more firmly and surer to keep the cheeks together; this Summer is only a Rail Tennanted, and let into Mortesses made in the inside of the Cheeks, and Screwed to them with long Screws, similar to those used for Bed-Posts; its depth four Inches and an half, and its breadth eight Inches, viz. the breadth of the Cheeks.”
