Inclined Plane Clock


A replica of a 17th century gravity clock, Dent of London made this model of the inclined plane clock as a smaller version of the more commonly seen model which has a brass & acrylic plane, made in limited numbers in the early 1970s. The wooden base has a tooled leather covered plane, its footprint measuring 60cm x 11cm. It is inset with a brass strip engraved with the days of the week.

The inner mechanism and clock face are weighted to keep them vertical, while the outer rim rotates as the clock drum rolls down the tooled leather plane. The clock traverses the entire plane over the course of one week. At the end of the week, the clock is lifted and replaced at the top of the plane, preferably on a Sunday. No further winding is necessary.

The movement is cased in a solid brass drum, with ridged edges.

The drum movement is driven by a large counterweight, regulated by a lever platform escapement . It has a silvered brass dial with Roman numerals.

It should be stressed that this clock is not branded for Dent of London, although every aspect of its mechanics assures me that it was from the Dent factory. The silvered dial is a plain version of the usual sunburst design (perhaps making it easier to tell the time by?). The backplate is inscribed with a dedication to Hans on his retirement from the Retrofitters in 1991. I would hazard a guess that the Retrofitters department that Hans may have worked for was with Dent of London, and this was made for him in 1991 from the remaining parts in stock.

The movement is to be overhauled and guaranteed for 3 years. The price includes delivery within mainland UK.
