Daniel Quare

Died 21 Mar 1724 (born c. 1648).English clockmaker who was one of the most eminent of his time, with wealthy clients for his clocks, barometers and mathematical instruments. In 1680, he invented a repeating pocket watch mechanism which struck the nearest hour and quarter hour on a bell inside the case when a pin was pushed, thus giving the time even in the dark. On 2 Aug 1695 he received a patent for a portable weather-glass (barometer) which "may be removed and transported to any place, though turned upside down, without spilling one drop of the quicksilver, or letting any air into the tube." Quare's elegant barometers had a wooden or ivory column resting on brass feet, with a brass compartment with a glass front to read the measurement scales at the top of the barometric tube.«[Image: Repeating pocket watch by Quare, circa 1700]

The robbery

Two friends, Jim and Paul are in a bank, when, suddenly, armed robbers burst in.

While several of the robbers take the money from the tellers, others line the customers up against a wall and proceed to take their wallets, watches, etc.

While this is going on, Jim slips something into Paul's hand. Without looking down, Paul whispers, "What is this?"

Jim replies, "It's that $50 I owe you."
