Dent Inclined Plane Clock, for Charles Frodsham

£5700

A replica of a 17th century gravity clock, this inclined plane clock by Dent dates from c.1973.

The inner mechanism and clock face are weighted to keep them vertical, while the outer rim rotates as the clock drum rolls down the 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.

Dent made a limited edition of 500 of these fascinating rolling drum timepieces in 1973, most of them sold under their own name. This example was made by Dent for Charles Frodsham, and bears the signature for Charles Frodsham on both the pyramid on the base and on a brass plaque applied over Dent’s signature on the dial.

Dent and Charles Frodsham were both highly esteemed names in the English clock-making world in the 1970s and earlier.

The drum movement sits on the inclined leather-covered brass plane, held on by friction alone. Over the course of a week, it travels down the plane. The dial chapter ring remain upright at all times. The clock is wound by simply lifting the drum and replacing it at the top of the plane.

The back of the drum movement is plain brass, beneath the cover the movement can be seen to be signed by Andrew Fell, exactly as the others we have seen by Dent, and is numbered 077.

The solid brass base has knurled adjustable feet and tapering doric columns supporting the tooled leather slope, the sides of which are embellished with red perspex borders and a brass strip with engraved days of the week.

The signed drum movement has a silvered Roman chapter ring, engraved sunburst centre and pierced hands to the movement with lever platform escapement driven by a large counterweight.

Overhauled and guaranteed for 3 years. Complete with original sales literature.
