Indicator, McNaughts steam engine indicator consists of a tubular body to which a rotating sleeve is attached to an arm. A string that has been rolled around the tube at the bottom can be attached with an end to a moving machine part, so that the tube rotates with every stroke and is then returned to its original position by the rolled-up spring at the bottom of the tube. A paper is attached to the tube. A piston with piston rod is arranged in the body under a spring, which is moved up and down by steam or vacuum. The body is screwed onto the cylinder with the tap on the underside, so that the piston of the indicator moves up and down simultaneously with the piston of the steam engine and proportionally to the steam and vacuum pressure., P.N. Rijk (mentioned on object), 1865, brass (alloy), copper (metal), iron (metal), rope, h 35 cm × w 10 cm × d 5.4 cm
