112,643. Llewellin, W. M. Nov. 17, 1916. Watchmen's clocks.-The drum A is provided with a groove F which is wider than the remaining grooves and, in conjunction with a wider prong, G allows a special mark to be made by a punch J on a paper strip distinctively ruled with one space wider than the others as shown in Fig. 6. Alternatively, the distinguishing prong G may be made as a printing-device which may operate through an ink-ribbon.
