Abstract

Pantographs have been used for making exact copies of an ori- ginal on a larger or a smaller scale, These devices have also been used for constructing composite pictures from individual pieces adapted to be arranged on a predetermined order to provide a composite pattern (note U.S. patent 2,176,797) . A pantograph device has been suggested in U.S. patent 3,680,226, for tracing a professional type drawing from a rough sketch.

also been used for constructing composite pictures from
individual pieces adapted to be arranged on a predetermined
order to provide a composite pattern (note U.S. patent
2,176,797) . A pantograph device has been suggested in U.S.

from a rough sketch.

It has been found that one can employ a 1/22 pantograph

handle 4 is reduced to 1/22 size by means of the four panto-
graph arms 6 which pivot about a pin 7 secured to the base-
board 1. A retractable stylist 8 transmits the input to a
film base (16mm) 9 which is carried on a plurality of reels
10, The reels are advanced by means of a pair of crank-type
handles 11.
