PORTICO CLOCK Le Roy h.r du Roi a Paris Ca. 1825 France
Signed: Le Roy h.r du Roi a Paris
The spring-driven brass plated movement consists of going and striking trains. The going train has pinwheel escapement and a compensation pendulum with beat regulation. The striking is regulated by an outside count wheel and indicates the hour fully and the half hours with one stroke on a bell, which is mounted on a support on the backplate. The clock is wound from the front.
The clock has a circular white enamel dial with a Roman chapter ring with five-minute and minute divisions. There are two winding holes, symmetrically positioned near the IIII and the VIII. The time is indicated by two blued steel Breguet hands. In addition, the clock has a blued steel central sweep seconds hand. The dial is surrounded by an engine-turned firegilt brass bezel. The dial is signed below the middle Le Roy h.r du Roi a Paris.
The firegilt brass case consists of an upper and a lower block connected by four columns. The circular movement is situated between the front two. The compensation pendulum is made of firegilt brass and steel. There is a rating nut beneath the compensation grid with which the movement can be regulated. There is a gilt brass box on the lower block under the pendulum with the text DEGRES DU CIRCLE and a graded scale 4-0-4. The pendulum oscillates within this box. The upper block has a plain frieze with a moulding at the top and an ornament in the middle. The whole rests on four engine-turned bun feet.
