Résumé
FIGURE 40 is A PHOTOGRAPH of the strike components located on the front plate of the movement. The clock strikes hours and quarters on two bells. Hours are struck on the larger bell, whereas quarters are struck on die smaller one. The strike mechanism and die manner by which it operates are unique and different from other tall-case clocks. The hour rack and snail are shown in Figure 41, whereas the barely visible quarter snail appears in Figure 42. All strike sequences begin with die strike of the hour followed by the striking of the quarters. The bells have individual hammers both of which are operated by the same lift lever, pinwheel, and gear train. The number of strikes on each bell is controlled via two racks. One rack counts the number of strikes for the hours, which then continues to be advanced during the quarter strikes, a second rack then counts the number of quarters and is responsible for ending the strike sequence. The method by which the sequence operates is intriguing. THE MANUAL REPEAT AND WARNING PHASE A strike sequence begins with a warning phase. Figure 43 illustrates the components involved in the warning. A wheel driven by the minute shaft rotates once per hour and, having four pins in its rim, causes the warning for each of the hour and quarter operations. The trip pins lift the warning lever in preparation for the strike, and releases it on the hour or quarters as selected by the setting on the dial. The hour pin is longer and protrudes out farther than the quarter-hour pins. By moving the warning lever closer to the front plate, striking will occur on ever}' quarter because each pin will cause a trip. By moving it slightly farther out, striking will occur only on the hour because only the long pin will cause a trip, and moving it still slightly farther means no strikes will occur. This is similar to the operation of the music trip selection in Figures 66 and 67 in the description of the music train operation. The last strike sequence may be repeated manually by lifting the repeat lever and releasing it. Although the repeat lever may be raised at any time, a strike may not begin if a strike warning operation is in progress. A repeat will not occur because the warning lever will not fall until the trip has been completed. During a warning, when the lever is raised, the racks fall to the left (counterclockwise) and the strike sequence is ready to begin. However, an extension on the left-hand end of the warning lever protrudes through an opening in die front plate, preventing the train from running as long as the lever is lifted. The protrusion prevents the train from running because it moves into the path of a pin placed in the rim on the wheel that drives the strike fly. The wheel is drawn with dashed lines to illustrate that it is located between the front and rear plates. The strike train is arrested as long as the warning lever is in the raised position. When the racks drop, their travel is limited by their tails, each of which contacts a step on their corresponding snail. The height of the step under each rack tail determines how many teeth are required to be gathered during the strike. COUNTING THE STRIKES Figures 44 and 45 illustrate the hour and quarter racks in greater detail. Note that the upper edge of the hour rack in Figure 44 has three distinct sections. Starting on the right-hand end of the sector and progressing toward the left, there are fourteen shallow teeth along the top edge, followed by four teeth that are cut approximately twice as deep as the shallow teeth. These deeper teeth are then followed by a smooth tail on the left-hand end. The surface of this smooth tail is located approximately at the same height as the bottom of the shallow teeth. The hour snail is mounted on the hour gear and rotates clockwise once in 12 hours. The snail is shown in the one o'clock position. Figure 45 illustrates die quarter rack. …
