DeMIRE, Ghent, Belgium, c. 1770 - 1780's. Two train with rack and snail strike.
Brass plate and spacer frame. Pinwheel escapement with adjustable pallets. One second
brass and steel rod pendulum. Knife-edge suspension. No maintaining power. 18.5"w x
13.5"h x 19"d.
The design and frame materials used for this small tower clock indicate that it was
made to be seen. (Although with the lack of maintaining power, accuracy was not a high
priority!). Notice how the frame central curves are designed to match the curvature of the
second wheels in the time and strike trains. The decorative heart signet in the pendulum
is also duplicated on the lower center section of front and rear frame plates. All of the
inner wheels spokes are nicely beveled. Another unusual feature is the way the snail for
the striking is advanced through a crude worm and rather nicely made associated gear. The
fly fan is probably a replacement. The overall dimensions are a bit unusual in that the
movement is deeper than it is wide. This is done to lengthen the width of the barrels so
as to increase the duration. The downside of the approach is the fact that all arbors of
the movement must be made to the same length of the barrels. This increases cost. Also
longer arbors are weaker and more prone to damage. One way to get around this is the use
of the 'chair frame' design (also known as double frame design). This concept uses a long
barrel with short arbors in the rest of the movement. An example of this can be seen by
clicking Cretin. Also note the ring at the top of the
pendulum rod. It does not serve as a safety device to keep the rod and bob from falling in
the case of a suspension spring failure, because there is no suspension spring. The top
part of the inner ring has the knife blade that seats into a slot on top of the large rod
supporting the entire pendulum assembly. You can see other examples of clocks with rings
at the top of their pendulums that do serve as safety devices in the event of suspension
spring failure by clicking Hors2, Horz3, and Hainz.
