In our last episode your local horologist was confounded by the "seconds" dial of the Vienna single-weight Regulator . Some of the answer to this conundrum lay in the history of the manufacture of these clocks.  The very earliest models of what became this classic style were created in about 1780 in Vienna. They were hand made by individual clockmakers and often of amazingly high quality. The style grew in popularity, over time evolving into several distinct variants matching the tastes of the times.  Of those of you familiar with Viennas the first image you might have when thinking of a one might be something more... ornate than our example.  Perhaps something like one these: Our Vienna is a bit more... modest in design. Again a photo as it was found on the wall when YLH first saw it. In that regard the observant reader / follower of this blog (thank you) might have noticed this tidbit from YLH's first posting about this clock, noted in its earlier owner's receipt ....

An adjustable deadbeat

Wha'dju call me? Well let's explain. In our last episode your local horologist was just about to discuss the removal and examination of the wheel train of the single weight Vienna Regulator.  The wheels looked to be in good shape but YLH was focused on the clock's escapement and in particular, its anchor. Recent readers will recall that an anchor engages with the teeth of the escape wheel and together they form the escapement . The escapement is the heart of the mechanical clock and fascinates your amateur d'horologie.  The anchor is the principal component of the escapement that drives the pendulum. The two major types of anchors are the recoil (a very early form of anchor and most commonly seen in mass-produced clocks) and the deadbeat (a later variant and more prevalent in European and higher quality clocks). There are many other types of escapements, some very exotic . Frequently attributed to  George Graham , the deadbeat was actually created by Richard Town...

Of pins and needles

In our last episode your local horologist was contemplating Newton and how his famous force enabled  was presently unsuccessful in the proper operation of the so called Gravity clock.  As a brief reminder our round friend rides a metal rack and when raised to the top and released it should slowly descend along the rack over the course of a day. See the prior post for details. Except our chonky ticker wouldn't.  It mostly fell (well if allowed to). This burgeoning clockmaker had a sneaking suspicion of what lay underneath the dial and the nature of the problem.  No time like the present! The dial is retained with two screws (crude design says this clock snob) and when lifted up and away must be carefully snaked along the hole from which protrudes the pendulum (as there is no way to remove the pendulum first) for proper extrication. A confession.  That's actually not a pendulum in the strictest sense because it cannot swing independently from the movement. It's a...
