Mechanical drum

Inv. 9902
Interpretation by Alessandro Siriati, 1952 - 1956

This drum on wheels is designed to be attached to a cart and work automatically taking advantage of its movement. The drum was able to reproduce a rhythm that repeated cyclically, probably for following troops: the axle of the cart’s wheel actuates a toothed wheel connected to a shaft which in turn triggers two cylinders equipped with notches of different heights which actuate five strikers, or beaters, on each side of the drum.

The model is based on the drawing:
