Conical pendulum clock by Henri-Eugène-Adrien Farcot, sculpture by Albert-Ernest Carrier-Belleuse, located in Main Building, Drexel University, Philadelphia, Pennsylvania, USA. 
<p>George William Childs purchased it for his drawing room at 2128 Walnut Street. Eighteen years after Childs’ death in 1894, his wife donated the clock in 1912 to the University in his memory. The clock was purchased at the Parisian Universal Exposition of 1867 for a staggering $6,000, making it at the time one of the world’s most expensive clocks.
</p>
Conical clocks have a pendulum that operates in a circular motion as opposed to side to side. This artwork is in the public domain because the artists died more than 70 years ago.
