Bernard Forest de Bélidor. Architecture hydraulique. 1737. Chapter II. Des Moulins a Scier le Bois. Plate 3. An early version of a type of muley saw – the bottom of the saw is connected directly to the pitman and the top connected to a small frame that rides in grooves. The Belidor version does not have guides for the saw that hold it vertical during sawing. Predates the Israel Johnson US Patent for a muley saw in 1826 (X4331).
