Oak Cased Thirty-Hour Longcase Clock.
Flat-topped square-trunk oak case with pine backboard. The hood, trunk and base all have carved decoration. The hood waist has a double convex moulding and the sides are simple oak boards, carved with a geometric diamond pattern and ivy leaf border. On both sides are attached hanging helical-twist columns with turned bobbin ends top and bottom. The hood front has no door. A planted half round bead runs round the inner edge of the glazed opening and hold the glass in place. There is no mask. The hood front frame is carved with an ivy leaf pattern. The fret aperture is now blocked with a single piece of timber. The top board has a recent add-on piece at the back. The plain chamfered cornice is a recent addition.
The front frame of the trunk is carved with an ivy leaf pattern and two oak leaves above the door. The oak trunk door is boldly carved in a geometric pattern and a half-round bead runs round the four edges. An oval lenticle opening is cut into the door. The thin iron butterfly hinges are fixed with nails. The door has no lock, but is held friction tight within the frame, and has a turned wooden knob.
The rectangular base has a framed raised and fielded panel decorated with a pattern of intersecting circles. The frame is carved with an ivy leaf pattern.
The modern unattached stained soft-wood seatboard has a slotted serpentine cut-out to allow the weight chain, pulley and doughnut to pass through, as well as a deep notch at the rear to accommodate the pendulum rod.
Square brass 'cartwheel' style dial plate with eight pierced segments. The dial centre is matted. Four brass 'urn an scroll' spandrels. Applied brass chapter ring with Roman hours I-XII with elaborate arrow-head half-hour marks. Around the inside a circle for quarter-hours, with later scratched divisions every 5 minutes.
Below XII a large ringed circular aperture, with a small square aperture to the right, reveal the phase and age of the moon 1-29 ½ displayed by a revolving disc, with heart-shaped cut-out, mounted on the back of the dial. The blued-steel background with painted stars is a modern replacement. Above VI o'clock within an aperture with an engraved border is a brass ring engraved 1-31 for the date.
Decoratively pierced steel single hand with a long pointed tail, possibly a replacement.
Weight-driven, 30-hour movement with rectangular brass plates and four knop and ringed pillars. Brass shrouds and sprockets with Huygens endless chain drive. Two wheel going train, the brass wheels with four crossings. Anchor escapement, the brass escape wheel with four crossings. Pendulum control, the pendulum with steel rod and a lead-backed brass bob.
Three-wheel striking train and fly pinion, for hours only controlled by a count-wheel mounted on the back plate. The bell is missing. The bell standard lacks its threaded section at the top.
The motion work consists of a pinionn of report on the extended great-wheel arbor which drive a central dial wheel on which is a friction-tight twelve-point star wheel for strike release. A single flag on the dial wheel arbor advances both the date and lunar wheels twice per day.
The drive chain passes around a solid brass pulley and through a lead 'doughnut' counter-weight.
