Thread Scale
The thread scale at the left was used in the textile industry to measure the number of  threads per inch in a sample of cloth. It has three scales, once silvered, that rotate in the view of the eyepiece. The lever behind the eyepiece disengages the screw from the nut, allowing the carriage to be located any place along its travel.

   The base is 8.7 cm wide and 6.7 cm deep.

   The scale was made by Chronik Brothers of New York, and sold by Charles Lowinson of New York. The patent dates are Oct. 20, 1908 and Sept. 20, 1930.

   It was donated to the Greenslade Collection by Daniel Chaucer.
