Object Details
- Stanley, William Ford
- Description
- This instrument consists of four hollow brass bars with square cross section. Two bars (labeled B and C) are about twenty-four inches long, the other two (the front one labeled D) are about twelve inches long. The two long bars are joined on their left ends. The two shorter bars are joined at their right ends. One short bar also is screwed to each of the longer bars. The bars move on five casters attached to them.
- The long bar (B) and the short bar (D) toward the front of the instrument both have scales that run from 1/2 to ¾ and then from 2/5 to 1/10. These two bars also each have a sliding head upon them. The front one attaches to a heavy black triangular weight stored in the case. Bars C and D hold the tracer and pencil point (or conversely). A mark on one of the bars reads: STANLEY, LONDON.
- Not all of the pieces of this pantograph have survived.
- The instrument fits into a wooden case.
- For a detailed discussion, see Stanley.
- The owner of this instrument wa probably the civil engineer Llewellyn Nathaniel Edwards (1873-1952).
