In study of theory of machine four bar mechanism is very important. Pantograph is one of the examples of four bar
mechanism. Generally it is nothing but the parallelogram used for the copying the profile. A pantograph is a simple yet powerful
tool which can broaden the scope of artwork and crafting. We can copy images to a reduced or enlarged scale with a pantograph
depending on how the parts are measured and assembled .The pantograph in the illustration would produce a copy of the
original. In this topic we “design, develop and analyze the portable pantograph for engraving required shapes or design on
wood.” Our pantograph is light weight and portable. Also copy with that different scaling of the letters is main work of this
pantograph.
