Then the increase in accuracy due to the introduction of the pendulum and balance spring in the mid 17th century focused attention on error caused by the escapement. This caused a shift from measuring time by continuous processes, such as the flow of liquid in water clocks, to repetitive, oscillatory processes, such as the swing of pendulums, which had the potential to be more accurate. [3][18][22], The earliest description of an escapement, in Richard of Wallingford's 1327 manuscript Tractatus Horologii Astronomici on the clock he built at the Abbey of St. Albans, was not a verge, but a variation called a 'strob' escapement. The moment of inertia of the foliot or balance wheel controls the oscillation rate, determining the rate of the clock. Is there a rule of thumb on how to properly adjust the DEPTH of the verge?? Drawings for the clocks 1, 2, 4, 5 in PDF format can be downloaded here, they are drawn to scale so that they can be printed at full size on either A3 or Super B papers. The verge escapement consists of a wheel shaped like a crown, called the escape wheel, with sawtooth-shaped teeth protruding axially toward the front, and with its axis oriented horizontally. The addition of a pendulum to the mechanical clock improved its accuracy and allowed a more precise measurement of time.

Move the pendulum to either side slightly with a finger or hand and then release it. The escape wheel tooth, pushing against the pallet each swing, provides an impulse which replaces the energy lost by the foliot to friction, keeping it oscillating back and forth.

In England, high end watches went to the duplex escapement, developed in 1782, but relatively inexpensive verge fusee watches continued to be produced until the mid 19th century, when the lever escapement took over. The escape wheel must have an odd number of teeth for the escapement to function. The pendulum loses energy because of friction. A quick discussion of the Verge Escapement.
