Abstract

22,363. Blume, A. Sept. 29. Going trains; winding- mechanism.-Fig. 2 shows a rear view of the clock with the back-plate, balance, and mainspring removed, and Fig. 3 is a side elevation. One end of the mainspring R is fastened to a post on the back-plate and the other end to the winding-arbor o, the first wheel k of the train being loose on the arbor and provided with a spring pawl m<1> to engage a fast ratchet pinion m. A pin m<2> is provided on the wheel to prevent the pawl from springing away. As shown, the striking train is similarly driven. Motion-work.-A frictiontight arbor o<1> bearing a wheel p and pinion q fits into a hole in the winding - arbor and drives the hands on central concentric arbors with pinion r and wheel s. The minute-arbor ends in a knob for setting the hands by. Escapements.-The escapement is of the chronometer type, but the escape-wheel c is made with teeth of the special shape shown and the discharging-pallet e has a snail form. Balances.-The balance d is a heavy square-notched wheel. Alarms.-The hour-pinion q drives a friction-tight wheel t on an arbor which bears a notched wheel x, and can be turned by a knob so as to set the notch to any time. The striking gear is set free when the notch in the disc sets free a detent.
