french cylinder escapement carriage clock

This compact little carriage clock features a French cylinder escapement. The horizontal or 'cylinder' escapement was invented by Thomas Tompion in 1695 and perfected by George Graham in 1726. Clockmakers found it suffered from excessive wear, so it was not much used during the 18th century, except in a few high-end watches with the cylinders made from ruby. The French solved this problem by making the cylinder and escape wheel of hardened steel and the escapement was used in large numbers in small clocks from the mid-19th to the 20th century. Rather than pallets, this escapement uses a cutaway cylinder on the balance wheel shaft, which the escape teeth enter one by one. Each wedge-shaped tooth impulses the balance wheel by pressure on the cylinder edge as it enters, is held inside the cylinder as it turns, and impulses the wheel again as it leaves out the other side.
The gilded case is finished with double oval design, making this a very special and unique timepiece! Height: 5 inches.
