Conservation of the Barnstaple (L&B) Signal Box – Part 3

1st May, 2024

Window framing  and surrounds

The next items to receive attention are the upright frame members located at the mid-point along the front, back and Lynton end of the box. At the Lynton end there was a tenon joint where the upright joins both the window sill and the lintel. On the front and back walls, there was only a tenon joint at the top, and these uprights were joined to the sill by 4 off 4" nails driven diagonally through each face. These differences perhaps give a clue as to how the signal box was erected. With tenons on every joint in the frame, the Lynton end of the box was probably assembled flat on the ground or in a workshop. The same was probably true for the Barnstaple gable end as well (TBC). On the other hand, the intermediate uprights on the front and back walls could have been inserted after the sills and lintels were already in place, i.e. once the rest of the signal box frame had beeen erected.
