Howard Model 1 tower clock is a mechanical pendulum clock characterized by five mechanical systems. The first requirement is a motive force, which in this case is comprised of weights that rotate the main barrel, but is sometimes comprised of a mainspring.

The main flow of power in ratchets and genevas, for example, is through the intermittent motion mechanism: on the other hand an escapement, which is a control device is operated at low power levels even when it is releasing energy from a high-powered source.

escapement, and torsional pendulum as listed in Table 1 and labeled in Figure 2. 17 In brief, the two-piece bellows canister, housing the ethyl chloride-fi lled bellows and stiff coiled return spring, attaches to the circular retainer on the back side of the rear support plate with a twist-ing motion. A winding chain, pinned to an endcap supported by a soft coil winding spring, follows and

  • 10/08/1971 · A ratchet wheel 24 is keyed to the drive shaft 22, and it is engaged by a double-acting pawl 26, the pawl being pivotally mounted on the stationary support 10 by means, for example, of a screw 28. The double-acting pawl 26 forms an escapement mechanism with the ratchet 24, and the action is such that when the pawl is set in the angular position shown in FIG. 1, rotation of the ratchet …

  • Escapement mechanism for pendulum clocks Abstract. A pendulum clock mechanism may have an escapement coupled to a conventional pendulum bob by means of an anchor arbor which is frictionally or slip coupled to an anchor having at least a pair of pallet pins symmetrically disposed thereon for engagement to an escape wheel.
