Escape wheels such as Kieninger escape wheels andSeth Thomas escape wheels are available here at Perrin's. The time keeping with this mechanism is not as good as that of a pendulum because of the numerous variables within the mechanism, but adjustment by positioning the two weights on the Foliot arm can bring it within a reasonable accuracy. Although no other example is known, it is possible that this design preceded the more usual verge in clocks.[23].
