Observatory standard regulator signed ‘R. Haswell & Son London’.
This is a recently completed restoration project. The clock came in missing several important parts, most importantly the large brass movement support bracket.
The bracket was researched and the system found to be similar to one used by Dent. The bracket was made from scratch and is formed from a solid brass back plate mounted to a solid cast iron wall hanging plate. The movement brackets were cast using patterns made from Pear wood. A great deal of machining was required to complete the bracket, the most complicated of which was machining the tops of the brackets to ensure that the movement sat properly in the case with the winding square lining up with the hole in the glass.
The completed bracket was finished with a Damasking ‘swirly’ pattern. The case is held to the bracket with a set of very scientific looking brass bolts which were made to match the marks on the back board.
The movement restoration was fairly straightforward, a testimonial to the quality of the original manufacture.
Interestingly the original maker of this movement is known as he prominently stamped the front plate:
D.J. Parkes & Son, 51. Spencer St, London E.C.
Another important missing component was the weight pulley. This was again copied from a Dent design with the end stops made in steel to match the end stops on the back of the movement.
The beat set adjuster at the top of the crutch was bent and had been mistreated at some time. This was corrected and new knurled thumb screws made.
The driving line was sourced to match the size dictated by the hole in a rather nice steel end piece mounted to the barrel. This was not knotted but expanded using heat to prevent it from pulling back through.
The pendulum was stripped and restored. The dial and beat plate were restored and re-silvered.
The case was restored sympathetically and waxed. The hood is held on by a series of latches, one of these was missing and had to me made. The case work was undertaken by Guy Marshall Restoration
On the rear of the clock is the remains of a label seemingly linking this clock to the Royal Observatory in Greenwich. The label is badly damaged and only a few words can be read. If you can make out any of the text or know any history which may be relevant then please do get in touch.
