Abstract:
The invention relates to timers and, more specifically to those timers powered by the output of a bimetallic element that is exposed to changes in temperature. A long existent need has been felt for a simply and inexpensive constructed timer capable of accurately initiating an event days or even weeks in the future. Present long-term timers require either, expensive and often unreliable batteries, or complicated timing escapements, and, on occasion, both. Such timers are utilized in a variety of applications, particularly in the military area. These include a variety of self-arming and self-destruct mechanisms. The present timing device is wholly mechanical, is self-contained, and is independent of reliance of any electro-chemical battery.
