Abstract: 104,021. Vezey, A. E., and Hatchman, A. J. Feb. 17, 1916. Change-giving apparatus.-A till comprising drawers or receptacles containing change, which are unlocked on the insertion of a currency note, is provided with one or more pairs of coacting electric contacts between which the note passes and thus prevents the completion of a circuit which, if established, would prevent unlocking of the change-receptacle. In the construction shown, the till comprises a drum b rotated by a handle h and adapted to receive the end of the currency note beneath pivoted spring-pressed grippers c, which are raised by a fixed cam d during a portion of each revolution. The note is drawn between fixed contacts e<1>, f<1>, g<1> and contacts e, f, g on the drum. The drum contacts are of different lengths, as shown in Fig. 6, and the fixed contacts are so set that, if the drum is turned without a note being inserted, contact between f, f<1> is established first, in which case a circuit is closed over a cut-out p in the main circuit, and operation of the releasing-solenoids &c. of the change-receptacles is impossible. If a tenshilling note is turned with the drum, it extends to the line x-x, Fig. 6, and contact is first made between e, e<1> to complete a circuit over the controlling-solenoid &c. of the drawer m, which can then be withdrawn to remove the corresponding change. On the releasing-catch m<1> of the drawer m being actuated, it joins the contacts 8 and completes a circuit over a cut-out q, which breaks the control circuit of the drawer n. When a onepound note is inserted, it entirely covers the contact e and extends to the line y-y; contact between e, e<1> is thus prevented, but the contacts g, g<1> complete a circuit over the releasing-solenoid &c. of the one-pound change receptacle n. Fig. 4 shows a section through one drawer m. This is normally locked by a projection m<3> engaged by tha catch m<1>, which is retained in the raised or disengaging position by a pivoted or spring arm m<4>, after operation of the solenoid, until, by withdrawal of the drawer, the projection m<5> strikes the arm m<4>. When the drawer is pushed back, the inclined upper end of the projection m<3> passes beneath the catch m<1>. A drawer k receives the notes, which are stripped from the drum by a hooked spring j, Fig. 2. The change may be contained in a number of superposed receptacles 10 adapted to be removed singly by the drawer. A signal may act in conjunction with the cut-out p, which may be reset automatically or manually. Also, registering, indicating, or counting apparatus may be fitted, and the drum may be replaced by a plane or other surface across which the notes are drawn. According to the Provisional Specification, the change-drawers m, n are operated selectively by circuits controlled by a two-way switch, which, in one arrangement, is manually operated, the drum and casing being then provided with only two sets of co-acting contacts; if three sets of contacts are provided, the third set controls a circuit over an electro-magnet &c. adapted to operate the two-way switch.
