D187. A fine quality Regency mahogany longcase regulator by Robert May of London
(Stepney.) It has a particularly good case with a mahogany carcase having a 1" thick backboard. The trunk door, with canted corners to either side and the base , which is panelled, are veneered in well figured mahogany.

The hood has a shallow arched top with stringing inside following the shape of the arch. This has a delicate mould to the upper edge and gadrooning below, which is carried round to the sides. These have blind rectangular panels. There are “ears” to either side of the top of the hood in the classic regency “Egyptian” style.

The well executed five pillar movement has substantial stepped plates, dead beat escapement, maintaining power and beat regulation. The wood rod of the pendulum has been gold-leafed to minimise the effect on it of any changes in humidity. Crutch tolerance (clearance.) may be adjusted by screws to either side. The very heavy brass cased lead bob is provided with a calibrated and silvered regulating nut.

An interesting feature is the substantial brass pendulum support bracket, screwed to the back-board. This incorporates a slider so that the pendulum may be moved from one side of the case to the other, to centralise it. It could also be used to put the regulator “in beat “, however a separate mechanism has been provided to perform this function.

The 12" diameter engraved and silvered brass dial has a centre-sweep minute hand with roman numerals, a seconds ring below 12 o’clock with arabic numerals and five second bars and an hour ring with roman numerals in the lower half of the dial. It is signed Robert May Deptford.

Robert May is recorded as working between 1828 & 1839, although he may well have been active both before and after these dates. It is likely that he had a particular interest in precision time-keeping as he received an award from the Society of Arts for a detached escapement. This is described in their Transactions, Vol:- 46.
