Object Details
- Davis, Gabriel
- Description
- This brass pantograph consists of four rods. These rods are marked near their ends as follows: B; D; [nothing]; C. The adjacent B and D rods are both marked with scales that range from 1-2 to 1 to 12. There are screwed slides for them (one is loose in the case) which have holders for points. The C rod also has a round holder, but it does not slide. Two short brass rods (one a tracer point) fit in grooves in the lid. The pantograph moves over the paper on six ivory-colored wheels. No weight. No pencil point. A mark on one arm reads: G. Davis / Optician / LEEDS.
- Compare MA.317868, MA.327891, MA.334888, and 2005.0182.8.
- The inscription is that of Gabriel Davis, an optician in Leeds who was active from 1822 to 1847. While this pantograph was sold by Davis, it was probably made by Cary.
