content: This 2-1/4" German silver and steel metal drawing instrument consists of a teardrop-shaped plate to which is attached a mechanism that is supposed to hold a larger serrated wheel and a smaller pattern wheel. The mechanism links the wheels to a bar that holds a pen point. When the larger wheel is rolled along the edge of a T-square or straight edge, the pen point bounces up and down to make a dotted line that formed part of an engineering drawing.
label: Description
content: The larger wheel (5/8" diameter) is marked with one of the trademarks for the Eugene Dietzgen Co., the superimposed letters E and D inside a circle formed by the letters C and o. The six smaller wheels (9/16" diameter) also have this trademark and are numbered from 1 to 6, representing six possible dotting patterns. All the wheels are made of brass. The instrument also has the trademark and is marked: EXCELLO. The arm holding the pen point is marked: DIETZGEN (/) GERMANY. The instrument is in a rectangular wooden bar-lock case covered with black leather and lined with green velvet. The top of the case is marked: DIETZGEN (/) “EXCELLO”. The top is also marked: GERMANY.
