Object Details
- Description
- This brass pantograph is stored in a wooden case with a lock (key missing) and two hook latches. Two arms are marked from 1/2 to 11/12. The instrument moves on six ivory rollers (one is missing). It is held together with screws. The pencil or tracer slides along one arm while the other point is stationary. An iron weight covered with black felt anchors the pantograph. The pencil holder has a cup at the top to hold weights to darken the pencil writing. There are no holes for the string.
- Engraving on one bar of the pantograph reads: John L. Wilson, No. 2. A tag on the front of the lid reads: PROPERTY OF (/) UNIVERSITY OF PITTSBURGH (/) PITTSBURGH, PA 15213.
