Abstract
Timers including an hourglass, a frame, and a trigger. The hourglass includes a top globe, a bottom globe, and a neck. The neck defines a sand passageway between the top globe and the bottom globe. The frame pivotally supports the hourglass at the neck. The trigger is pivotally coupled to the frame in a position to be engaged by the bottom globe when the hourglass pivots on the frame to a selected extent. The hourglass is configured to allow the sand to flow from the top globe to the bottom globe through the neck under the influence of gravity. The hourglass pivots on the frame in response to sand flowing from the top globe to the bottom globe. The selected extent the hourglass must pivot for the bottom globe to engage the trigger corresponds to a selected amount of time. Some examples further include a sonic device and/or a base.
