Abstract: 397,660. Cash registers. EMBERSON, F., 149, Maple Road, Penge, London. Aug. 2, 1932, Nos. 21675 and 22514. [Class 106 (i).] Autographic, arrangements ; totals, taking.- A cash register is provided with means to ensure that the amount of cash in the till is noted on an autographic strip prior to the reading or printing of a total. The invention comprises a lock-controlled device normally operative to prevent access to or operation of a total indicating and/or printing mechanism, and means whereby on operation of the device to inoperative or access-giving position, the step-wise winding-mechanism of an autographic strip is operated to feed the strip and thereby move the entry thereon past a writing- window to an inaccessible position. In the embodiment shown in Figs. 1 and 4, the usual control lever 3 is provided with an index 6 and with a lock 8 operable by a key 9. Movement of the lever to total-taking position is normally prevented by the abutment of a projection 24 thereon with a stop 27 on a pivoted cover 25 giving access to the window 18 of an autographic strip 17. Thus, before a total can be read or printed, the cover 25 must be unlocked and lifted to disable the stop 27 and the operator is reminded to enter on the strip the amount found in the till. The last part of the movement of the control lever, through lever 22, 23a and pawl 21 feeds the strip and, through mechanism not shown, unlocks the totalprinting mechanism or a cover to give access to the totalizer. The stop 27 on the lid 25 may, if desired, be replaced by a stop 51, Fig. 4, formed on the bolt of a lock 50 operable by a special key. In the embodiment shown in Fig. 6, the autographic strip 17 is fed during the first part of the opening movement of a lid 1a that gives access to the totalizer. For this purpose, the lid is provided with a stud 35 adapted by co-operation with the slotted end 34 of a lever 33 to rock a feed-pawl 22a downwardly. Opening of the lid 1a prior to the raising of a normally locked cover 25a giving access to the writing-window 18 is prevented by a arm 37 depending from the cover into the path of an abutment on the lid or, as shown, into the path of a projection 38 on the lever 33. In a modification, the autographic device may be attached to the lid of the machine and be actuated by a fixed part. In the embodiment shown in Fig. 8, the autographic strip 17b is fed by the lock 41 of the totalizer cover 1b, a projection 43 on the bolt 42 rocking a lever 46 that through rod 47 and arm 48 actuates the feed-pawl 49. Unlocking of the cover 1b prior to the opening of the lid 25b of the autographic device is prevented by an arm 60 on the latter depending into the path of the arm 48. Operation counters.-The autographic device may be provided with an operation counter for comparison with the reading on the usual counter that indicates the number of times the lid of the machine has been opened.
