17th and early 18th century windows were commonly of the casement type. Casement windows consisted of a pair of vertically mounted iron frames within which diamond shaped panes (called quarrels) were held in place by turned leads. The windows would swing outward on pivots located at the outside top and bottom corners of each half of the window. Casement windows were replaced by sash type windows around the middle of the 18th century. Turned leads are often a boon to archaeologists as they often contain a date of manufacture and manufacturers initials. No dates were found on the leads from the Taylor Homesite.
