Lumber Stick with Sixteen scales
Object Details
- Description
- This round wooden yardstick is divided into 16 scales numbered from right to left that divide the foot into various numbers of parts. The scales include: 8 (units of 1 1/2" or 3.8 cm), 9 (1 5/16" or 3.3 cm), 10 (1 3/16" or 3.0 cm), 11 (1 1/16" or 2.7 cm), 12 (1" or 2.6 cm), 13 (11/12" or 2.3 cm), 14 (7/8" or 2.1 cm), 15 (13/16' or 2.0 cm), 16 (3/4" or 1.9 cm), 17 (11/16" or 1.7 cm), 18 (21/32' or 1.6 cm), 19 (5/8" or 1.6 cm), 20 (5/8' or 1.5 cm), 21 (9/16" or 1.5 cm), 22 (17/32" or 1.4 cm), and 23 (1/2" or 1.3 cm) parts per foot. The number of subdivisions per foot is indicated at the right end of each scale, but these marks are badly worn.
- The left end of the rule is marked: PSP (/) April 25th (/) 1822. The right end is marked: PSP (/) 1822.
