Tills.-In cash tills, in which the amounts are recorded upon a travelling paper band C and a voucher or receipt delivered from another paper band or roll G placed at right-angles to the first, the voucher-delivering rollers are actuated by means of a screw or twisted spindle L. This spindle is connected to one of the delivery rollers K, and rotary or angular movement is applied to it by sliding a nut M over it or moving it through a nut. The roller D for receiving the recording- paper may be operated by a lever E and a rod or pawl F on the opening of the drawer B. The nut M is operated by a forked connecting-rod N and a lever R engaging a groove r in the side of the drawer B. The rod N is preferably pivoted to a plate 0 carrying a pawl o adapted to engage a notch in the nut M so as to cause the rotation of the spindle L in one direction only. The spindle carries a stop-pin l engaging a sliding bar P and released when it comes opposite a notch therein. The top voucher-delivering roller H may have a rubber printing-surface, and is held tightly against the bottom roller by spring-pressed levers. A spring- pressed inking-roller H<1> is provided. A cradle is placed between the delivery rollers, and has slots to admit the type. When the invention is applied to a coin-exhibitor till, the lever R carries a secondary arm, which operates the coin-exhibiting machine. In such a machine having a reciprocating sliding table, the coins in the first compartment are prevented from being projected forward, and mixed with those in the second compartment, by a bar or wire sliding over the face of the pivoted plates, which it locks when at the bottom. When the wire is at the top, the plates are free to oscillate to allow the passage of the coins. A cam attached to the reciprocating tray acts on an arm projecting from the bar or wire. In a modification, the fork N is secured to and reciprocates the screw L, which slides through a nut attached to or connected by a pawl and ratchet-wheel with the roller K.
