A&R rep for the Tigerstyle, Mike Treff, had previously operated his own record label named Linkwork Records.

The essential feature of this timekeeping device was a linkwork escapement quite different from the verge-and-foliot system invented in Europe in the late thirteenth century (ch. 7).

In Su Song's waterwheel linkwork device the action of the escapement's arrest and release are achieved by gravity exerted periodically as the continuous flow of liquid would fill containers of limited size.

As it went down it tripped two levers or weighbridges which by means of linkwork connections released a gate at the top of the wheel so as to let it move on by just one scoop.
