Abstract

The mechanical timer is capable of measuring for example three successive short periods of eight minutes each and sound an alarm at the end of each period. It comprises a box (14) with a front dial through which a spindle (18) projects mounting an indicator finger which also acts as a winder for an internal clockwork motor. As the motor unwinds it rotates a cam (37) whose peripheral cam surface engages a lug (48) of a "V"-shaped lever (44) pivoted at its bore (45). One arm (47) of the "V" acts on a second gear train (27) through a spigot (51) while the other arm (46) acts on a third gear train (32) via a spigot (50) adjacent the lug (47). The lever releases the second train (27) and holds the third train (32) to initiate the mechanical alarm for 3 seconds and then holds the second train (27) and releases the third train (32) to stop the alarm as the lever (44) is rocked by the lug (48) following the cam surface on the cam (37).
