Abstract: 173,875. Reynolds, W. E. Oct. 9, 1920. Money-delivering apparatus; tills.-In apparatus for giving change for Treasury and like notes of the type wherein a spring-controlled changedrawer is fitted beneath a vertical magazine containing superposed cash trays and is adapted to withdraw one tray at a time, and having mechanism which draws the notes into the apparatus and deposits them in an enclosed receptacle, a rotary note-receiving drum is provided between each note opening and the corresponding receptacle for holding the note and the note openings are provided with doors by the operation of which the changedrawer is partially opened, the completion of the outward movement of the change-drawer causing the drum to be rotated and bring into view the note just inserted into the drawer. The changediawer having been replaced and a fresh note introduced, the next withdrawal of the change drawer causes the drum to drop the first note into note receptacles and at the same time to bring the second note into view. The machine comprises a single casing containing two similar and independent sets of mechanism, one for dealing with 10s. notes and the other with ú 1 notes, arranged on opposite sides of the machine, and each set of mechanism is provided with two vertical change-tray magazines d, in such a manner that each magazine may be deposed above the change drawer in turn. The note openings n are each normally closed by a sliding door n<1>, which, when opened, engages the inner arm n<4> of a U-shaped rocking lever, attached rigidly to which is an outer arm n<6> pivoted to the upper end of a vertical rod n<7>, the lower end of which is pivoted to a rocking lever n<8> engaging the outer end of a trip lever n<14>. The inner end of the lever n<14> is hooked and engages a pin n<13> on the change drawer and at the rear of the change-drawer is a spring-controlled buffer n<11> slidably mounted in a bracket n<12> fixed to the base of the machine. The act of opening the sliding door n<1> causes depression of the rod n<7> by means of the intermediate mechanism, releasing the trip lever n<14> from the pin n<13> and allowing the drawer to be pushed out a short distance by the spring n", the completion of the opening movement being effected by the operator by means of the knob c<11>. The changedrawer carries a rack c<5> which meshes with a pinion j having a fixed arm j<3> to which is attached a connecting-rod k extending upwardly and connected to an arm l fixed to a driving- wheel l<1> gearing with a follower l<3> mounted loosely upon a spindle m which also carries the note-receiving drum m<1>, rotation of the drum m<1> being controlled from the follower l<3> through pawl and ratchet mechanism. A note having been introduced through one of the openings n into the rear upper compartment of the drum immediately beneath it, the operation of withdrawing the change-drawer causes the connecting-rod k to descend and thus rotate the note drum to bring the compartment into which the note was introduced forwards into view under the window o. The closing of the change-drawer causes the connecting-rod to rise and the wheels l<1>, l<3> resume their original positions by the action of a spring q<1> and arm q pressing against a pin fixed to the driver l<1>. The rack c<5> may be provided with the usual loosely-hanging pawl for preventing partial opening and closing of the change-drawer and the act of opening the sliding door completes an electric circuit to ring a bell. An arrangement is also described whereby the change-drawer cannot be drawn forward when the change-tray magazines are empty and also means whereby the drawer cannot be replaced unless the change tray is removed. The mechanism rotating the note drum also actuates an indicator for indicating the value of the note for which change has been given, 'and means are provided for locking the change-drawers so as to prevent their unauthorized withdrawal.
