Pulley stand. Lever suspended by 2 cords passing over 2 pulleys to 2 weights. The lever is thus balanced at 2 ends and is a "mathematical, weightless" balance with no fixed fulcrum. 3 notches in the lever divide it into 4 equal parts. Weights may be applied in these notches, and counterbalanced by weights in the cords.Ref: Det phys Cab vol 1 p 89, pl 15 fig 11.Not signed1800 app (g)
