Brass model of disconnecting cranks, by Boulton, Watt & Company
These items appear to be development models made by Boulton & Watt in the course of their work building rotative steam engines for use in mills and factories. The arrangement consists of two discs facing one another, one of which carries the crankpin and the other is secured to the shafting. Connection between the discs is made by three hinged tongues attached to the crank- plate, and capable of being dropped into three notches in the driving disc, springs retaining these tongues in the closed or open position.
