Workshop receipts
Workshop receipts is a practical technical handbook of trade recipes and processes, compiled by Ernest Spon, Robert Haldane and Charles G. Warnford Lock and published in London and New York in 1883 for tradespeople and workshop practitioners. Its pictures are plain line diagrams of apparatus in cross-section, with hatched walls, labelled parts and lettered references, offering a designer clean technical drawing conventions and schematic structure.
