Abstract:

In all three versions, the bottom rail has a flat, smooth bottom and does not tilt. In two versions, transverse horizontal holes receive ladder cords. In one of these versions, another horizontal hole opening at the rear of the rail extends obliquely into intersection with the transverse hole midway between the front and rear of the rail. A vertical hole extends down from the rail top to this intersection. A lift cord extends down through the vertical hole into the oblique hole where a knot on the lift cord fixes the end of the cord in the oblique hole. In too the other of these two versions, a horizontal transverse hole above each ladder cord hole receives a lift cord which extends out at the front and rear of the bottom rail. These lift cords, and the ladder cords, extend entirely up to the headrail. In this version, each slat has a notch at the front edge and rear edge, receiving the corresponding lift cord and ladder cord.
