Maker, Edward John Dent, London, c. 1840's no. 860. Jeweled deadbeat escapement, Movement plates spotted and wheel train fully jeweled up to going barrel, with half-second, mercury compensated pendulum compensation. Fine beat adjustment above two prong crutch and vernier rate adjustment . Silvered brass dial. Movement: 18.5"h (47cm) x 6.5"w (16.5cm) x 6.5"d (16.5cm). With base and case: 23.5"h (60cm) x 7.75"w (19cm) x 7.75"d (19cm). This example is illustrated in British Skeleton Clocks, Derek Roberts, pp. 231, 234.

Edward dent made a small series of these attractive table regulators in the mid 1800's. Derek Roberts puts this number at six to perhaps seven. He states "These were probably the most attractive clocks Dent ever made with their beautifully finished cases, finely engraved dials, with seconds hand, fully exposed movements." While all of them were similar in their architectural style of construction, they were highly individualized with different escapements, some with remontoire and varying amounts of jewelling. The body of the clock in some cases were silvered some places.

The known examples of this clock to the best of this author's knowledge are as follows:

Dent, 61 Strand, 507, detent escapement, possibly acquired by Dent post breakdown of the partnership between Dent and Airy (type unknown, probably the same as no. 508), location unknown.

Dent, 82 Strand, no. 508. Airy spring detent pinwheel escapement, c. 1836. Lord Harris collection, Belmont, England.

Dent, 33 Cockspur St., no. 521, Airy 30 second train remontoire, c. 1845, formerly in the Time Museum, Rockford, Illinois USA, private collection.

Dent, 33 Cockspur St., no. 522, Airy 30 second train remontoire, c.1845, private collection, USA

Dent, London no. 860, deadbeat escapement, fully jeweled movement, author's collection

There is another without a serial number that has Airy's spring detent escapement but no remontoire. It has some substantial design differences, the main being that the pendulum is suspended behind the clock frame and not within, The entire four pillar frame being somewhat narrower than the examples cited, the pillars of a different design as well as the base. Bonham's, December 12, 2018, lot #108.

In addition this writer did see another example in a small museum in Germany in September 2014, but unfortunately cannot come up with the photo or other information, it may be the number 507.


Advertisement in Antiquarian Horology, March 1976 of this same example.


This example from Charles Frodsham was made about the same time as the Dent examples but was a smaller version with the movement standing at just under 12" tall. A gridiron pendulum with lenticular bob hangs from behind the movement instead of from under due to the smaller size. Photo from a Derek Roberts catalog, June 1986.
