Abstract: 107,416. Paul, R. H. June 27, 1916. Adding-apparatus.-Relates to a card-game scorer of the kind having a number of concentric rotary score indicators or dials operated by a stylus and comprises : (1) the addition of a dial or pointer for indicating the trump suit and the number of odd tricks undertaken to be won by the declarant; (2) means for interlocking the trick and honours points indicator; (3) means for transferring points from the minor part of the grand total device to the major part, such means allowing also of independent operation of the major part for large additions to the total by means' of the stylus. The device has two similar sets of dials, one set for each of the opposing sides. In the upper half of Fig. 1 is shown the exterior of one set of dials the lower half of the figure showing the other set with the casing removed. In respect of each set of dials the upper face of the casing is marked with a dial divided into segments for various declaration suits 112, each suit being numbered 1 to 7 for odd tricks undertaken. A pointer 109 may be adjusted over the dial. The rotary score indicators consist of three concentric flanged rings without a central pivot, viz., a trick points ring 120, Fig. 3, a minor grand-total ring 127, and a major grand-total ring 138. The rings are perforated and numbered as shown in the lower half of Fig. 1, some of the perforations being displayed through segmental slots in the casing as shown in the upper half of Fig. 1, the numbers being displayed through orifices 126, 136, and 139. The casing bears numbers adjacent to the slots so that by inserting the point of the stylus into the perforations the rings may be rotated the requisite degree. Thus total trick points are shown at the orifices 126 due to rotation of the inner ring 120 and grand-total points are shown at the orifices 136, 139, due to rotation of the rings 127, 138 respectively. By means of a gravity pawl cooperating with ratchet teeth 130, Fig. 3, formed on a horizontal portion 129 of the minor grandtotal ring 127, an adding movement of the trick point ring 120 rotates the minor grand-total ring 127 a corresponding amount so as to increase the total displayed at the orifice 136, the two rings 120, 127 being otherwise independent. The major grand-total ring 138 is capable either of independent operation by means of the stylus, or of automatic operation at the completion of each revolution of the minor grand-total ring 127. Transfer mechanism; overthrow - preventing mechanism.-The transfer mechanism is shown in Fig. 2 and comprises a spring-pressed lever 151 pivoted to the casing on a pin 152 and carrying at an extremity a spring- pressed pawl 159 engaging a series of notches 146 in the major grand-total ring 138. At the completion of each revolution of the minor grand-total ring a projection thereon engages a tappet 153 and pushes back the lever 151 thus causing the pawl 159 to give a progressive movement to the major grand-total ring. A projection 170 then presses a pawl 166 into the notches 146 to prevent overrunning. A pawl 15 prevents retrogression. The pawls 165, 159 are shaped so as to allow of an independent forward movement of the ring by means of the stylus. A rotatable dial 108, Figs. 1 and 3, pivoted on a central pin 107, scores the games at an orifice 114 and a similar dial 119 indicates doubles and redoubles. In a modified construction instead of driving the minor grand-total ring by means of the gravity pawl and the ratchet teeth 130, Fig. 3, the trick-points ring 120 and the minor grand-total ring 127 may be provided with vertically aligned perforations so that the stylus may engage both disks at the same time.
