The most obvious difference when comparing it to the Swiss- and even the "Glashuette" escapement is the design and the type of banking pins.
The design was chosen this way, so that the lever were entirely balanced, which meant, that the main focus of the lever fell together with its rotating axle. H. Mueller said, that the pallets were shorter and did not come out as far as the other pallets use to. And this is suppose to have the advantage of oil remaining in place. (a little oil is filled in at the locking face of the entry pallet, which than accumulates in a front corner. From this little "reservoir" the teeth of the escape wheel constantly draw some oil).
Nevertheless, as H. Mueller said, the most important difference in the existing lever escapement lies in the allocation of the impulse. Here the impulse plane of the escape wheel and pallets are never parallel. This has the advantage that an adhesion at the impuls plane can not occur. As adhesion is depending on the viscosity and the viscosity on the other hand rises when the oil gets older this would have a negativ effect on the energy balance of the escapement. |
