This is a 30 hour or 1-day New Haven Ogee shelf clock. 1875-80 seems to be the approximate period of manufacture for this smallish Ogee clock. The case measures 18 1/2 by 11 3/4 inches (47cm X 30cm) and the hour strike movement measures 3 1/2 by 5 inches (9cm X 12.7cm).
So, its a bit of a miss-match. Imperfect but attractive just the same
This 30 hour New Haven Ogee shelf clock looks nice from a distance but closer inspection reveals a number of issues regarding the condition of the case. Although the sides panels of the clock are veneered, the front veneer has been stripped likely because of significant loss or damage. Crude chisel marks on the left front of the case suggest that the veneer in this section was tough to take off. This is unfortunate, but I have no intention of re-veneering any part of this clock. There is also veneer loss on the top right side. From a distance the entire clock actually looks good and the casual observer would not notice the difference.
It takes a#3 key to wind the clock. It is probably the only American shelf clock I have that uses a key that small.
The movement looks original to the case and there are indications that it has been worked on in the past. There are punch marks surrounding several pivot holes, an common old-style repair to close the holes.
The coil gong is a replacement and is in a slightly different location than the original gong judging from screw holes to its right. The gong is probably from an E. N. Welch or a Gilbert. The clock dial face is a recent addition and the access door knob looks like it is a later addition.
So, its a bit of a miss-match. Imperfect but functional.
The movement was dis-assembled and the parts cleaned in my recently acquired Quantrex 140 ultrasonic cleaner. The movement parts came out shining particularly the lantern pinions.
The pivots were in very good shape and polished up well with my Butterworth Bushing Polishing System that I use with my multi-speed Dremel tool. I decided to tackle only the worst bushing holes; the centre canon, back plate and the escape wheel bridge. Four bushings were also installed on second and third wheels, front and back plates.
Some consider 30 hour clocks as a hassle because they must be wound once a day but I am okay with that. This 30-hour Ogee clock runs very well, keeps good time and I am pleased with the servicing.
