Abstract: 168,347. Jofeh, J. March 30, 1920. Money-changing apparatus. -In apparatus for giving change for paper money wherein releasing-mechanism for coin receptacles is controlled by a pivoted finger or fingers across the path of the note into a groove in the note-feeder and adapted to be intercepted by the note to enable the release mechanism to be operated, the notefeeder is operated by handlever mechanism which positively operates the release mechanism during the feeding of the note and while the note is arresting the finger or fingers. In the fcrm shown, the feed-roller b has spaced longitudinal grooves b<10>, with one of which engages the leading edge of a note which is passed up the feed slide a<1>; the feed-roller is then operated through a pawl b<5> and ratchet b<4> from a handlever b<1>, the groove b<10> turning up the edge of the note to ensure the latter being gripped between feed-roller and spaced coiled-wire endless bands b<7> and carried into the apparatus. Near the end of the stroke of the lever b<1>, a spring-pulled member f<10>, carried by a lever d<6> on the shaft b<3> secured to the lever b<1>, engages a bell-crank lever f<6>, as shown in Fig. 1, which bell-crank lever is pivoted to the free end of a second bellcrank lever f<3> connected to a finger f<1>. The finger f<1> engages the note and prevents rocking of the bell-crank lever f<3> and the member f<10> therefore rocks the bell-crank lever f<6> against the resistance of a spring f<11> to depress a rod f<18> and thereby, through a lever f<9>, release a spring-pressed catch from engagement with one of a series of projections g<1> below the change magazine g; a spring- pressed member on the catch then engages the lower surface of the projection g' to prevent return of the catch. The hand-lever b<1> is then returned and at the end of its stroke, the arm d<6> depresses a push-rod m<1> to release a second catch from the magazine, which can then be rotated to permit removal of one of the sectorshaped change containers g<2>. A third catch h<6> prevents reverse rotation of the magazine. If the apparatus is operated without the insertion of a note; the two bell-crank levers f<3>, f<6> rock about a pivot f against the resistance of a weak spring f<4>, the finger f<1> then entering a circumferential groove in the feed-roller, and the first-mentioned magazine catch is therefore unaffected. During the feeding stroke of the hand-lever b<1>, an arm e<5> engages a pivoted arm e' and, through a link e<10>, spring e<13>, and arm e<12>, rocks a shaft e<1> to raise an obturator e to prevent insertion of a second note; if the obturator engages such second note, an arm e<2> on the shaft e<1> is held in such a position that its inturned end engages a pin e<4> on the arm e<5> and so prevents completion of the stroke of the hand-lever b<1>. A series of obturators may be provided. A bell d is rung at the end of each stroke of the hand-lever. The notes, after passing round the feed-roller, are deposited in a receptacle k. The magazine is rotatably carried by a frame g' supported in slides in the base of the casing a of the apparatus. When the magazine is to be removed, all the catches are released by means of a push-lever h. This push-lever may then be locked by a lever f<10> arranged to be engaged by the lower door a<3> of the casing, so that closing the door effects release of the catches. The apparatus may be duplicated, Fig. 4, for notes of different denominations ; the bands b' intended to grip a larger note and are then spaced apart by a distance greater than the length of a smaller note. An upper door a<11> of the casing is locked by a spring catch n which may be released by a depending lever n<3> only when the lower doors a<3> are open. In a modification, the note-feeding ledge a<1> is hinged at its outer edge and is normally held down by trip mechanism which is released during the feeding-stroke of the hand-lever to throw the ledge upwards against the bands b' and so ensure the latter obtaining a grip of the note.
