Description: | Combined roller copying press and writing desk. James Watt invented this document copier to relieve the tedium of making copy plans and drawings. The press copies a document freshly written with special ink by pressing onto thin, translucent, unsized paper, producing a reversed copy from the back. Watt patented the device in 1780 and his company continued to produce it long after his death. The principal on which the machine is based remained in use until the arrival of modern photocopiers. Metal processing tray in drawer, brass roller and felt board mangle for printing, detachable operating handle, folding writing desk, ink block, in polished teak case. Also letter written by Watt and copied on the copying press. | License: | http://www.stickii.co.uk/umis/termsandconditions.html#heriot-watt-rights | Publisher: | Heriot-Watt University Archive, Records Management and Museum Service, Edinburgh Campus | Rights holder: | 46182 | Subjects: | Education | Source: | Heriot-Watt University | Creator: | James Watt & Co | Identifier: | http://media.culturegrid.org.uk/mediaLib... | Go to resource |
