Mutoh drafting machines
Mutoh drafting machines are technical drawing tools made by Mutoh Industries Limited.
Background and Description
Mutoh Industries Limited, now known as Mutoh Holdings Co. Ltd, is a Japanese company established in 1952. They manufacture infographic equipment. They established a European division in 1990. One of their products, before they moved onto a more modern focus on computer aided design, was the drafting machine.
A drafting machine is a tool used for technical drawing. A pair of scales are mounted to form a right angle on a rotating protractor head. They have been around since the 1920s. The machine head is mounted on a drawing board with a hard, smooth surface, allowing tilting and lifting.
The use of computer aided design has seen the use of drafting machines reduce dramatically, and they are thus forming a collector’s niche. Many companies that used drafting machines gave them to their employees to take home with the move over to CAD, so there a rich resource of drafting machines exists.
There are several parts that make up a Mutoh drafting machine: a protractor head, scales, rulers etc. Some also come with heavy duty drawing boards and stands.
Some are battery powered with a digital screen to indicate the degrees of movement in the rotation and angle.
Mutoh drafting machines are offered for anything between £25-£450 on internet auction and trading websites.
