Abstract: 107,361. Bailey, R. D. July 3, 1916. Money-delivering apparatus. - Apparatus for giving change for Treasury and like notes comprises means for pulling the note through a pair of rollers arranged so that their rotational movement is governed by the length of the note and actuates means for unlocking the drawer of the change-containing receptacle. Three forms of apparatus are described. (1) The first, Figs. 3 and 5, comprises a casing provided with windows 7, 7<x> horizontally slotted to receive a one-pound note and a ten-shilling note respectively, external ledges 13 and internal guides 37 being furnished also. Opposite each note slot are two pairs of rubber rollers 29, 30 and 32, 33 in length of circumference respectively equal to one-half and the full length of the note, and urged together by springs. The rollers 29, 30 are geared together and to wheels 40 on shafts 41, each provided with a pawl 42, by wheels 38, 39, and the rollers 32, 33 also may be geared together. A driving chain 64 couples the rollers 33. and the lower one is driven by a handle 62 on its shaft 35. The shafts 28 of the rollers 30 are each provided with a spring- pressed clutch element 50 adapted to be engaged bv a hand-wheel 45, the movement of which is limited by stops 67 and resisted by a spring 56. A note is fed through its appropriate slot to a pair of rollers 32, 33 by turning the hand-wheel 45 of the corresponding rollers 29, 30. The handle 62 is then turned to actuate the rollers 32, 33 which pull the note through the rollers 29, 30, causing these to rotate further, and through the gearing 38. 40, to swing the pawl 42 round to strike a projection 58 on the spring-resisting bar 21 which is moved upwards out of locking engagement with the drawer 10. The clutch 50 is disengaged and the handle 45 returns to its initial position. If a ten-shilling note is inserted in the one-pound slot its length is insufficient to produce the necessary movement of the drawer-unlocking mechanism. The notes are removed through a door in the front of the apparatus, and side doors 14 give access to the tubes 15 containing the change-containing receptacles 18. The change drawers 10, 10<x>, respectively for giving change for a one-pound and a ten-shilling note, are each outwardly urged by a spring and provided with side ledges 17 for removing the lowermost change-container 18, and counter tapes for indicating the number of times each drawer has been operated and a bell 23 are fitted also. The rollers 32, 33 may be replaced by clips, &c. for drawing the note through the rollers 29, 30. (2) In the apparatus shown in Fig. 7, three pairs of rubber rollers 29, 30: 72, 73; 76, 77 are mounted behind each note slot, the rollers 72. 76 of both sets being carried by plates 78 coupled by rods 80 and normally retained in the uppermost position by springs 86 connected to levers 84 pivoted at 85 and coupled by pins 83 to the rods 80. Cams 107 on a driving shaft 90 coact with rollers 108 on the levers 84 to depress the rollers 72, 76 once in each revolution, and spur wheels 94, 95 actuate the rollers 30, 77 through intermediate wheels 96, 100. The spindles of the rollers 73 carry spring-resisted arms 104 for engaging the drawer-locking bars 21, and cams 109 actuate through levers 110 a shutter 68 which is provided near its upper end with a slot and prevents the insertion of a note unless the apparatus is in its initial position. In operation, the note is passed through the appropriate slot. either beneath the lower end of the shutter or through the slot near its upper end, and the shaft 90 is turned. The initial movement releases the levers 110 and causes the shutter to close the note slots; the note is gripped by tha rollers 29, 30 and drawn through the space between the plate 68 and the casing 1, and fed between the three pairs of rollers during the first seven-eighths of the revolution of the shaft 90; during the remaining eighth, the cams 107 force the rollers 72, 73; 76, 77 together, and the note is pulled by the rollers 76, 77 through the rollers 72, 73 which are thus revolved and actuate the arms 104 to release the appropriate change drawer. As the rollers opposite the slot for the one-pound notes are of greater diameter than those opposite that for the ten-shilling notes, should a ten-shilling note be inserted in the one-pound slot, it will be passed through the rollers 72, 73 before the arms 104 reach the drawer-releasing rod. The rollers 29, 30 may be circumferentially corrugated to ensure the straight feeding forward of the note. Each operation of the machine may be effected by a. half or full turn of the shaft 90, and in the latter case, the shaft handle is limited in movement by a sliding stop and is returned by a spring to its initial position after operating the shaft through a pawl and ratchet. (3) In the form shown in Figs. 9 and 10, the apparatus comprises two pairs of rollers 29, 30 fixed on shafts 27, 28, and between them, rollers 72, 73 secured on sleeves 27<A>, 28<A> loosely mounted on the shafts. These rollers have a circumference equal in length to the notes, and the shafts 27 are driven by gearing from a main shaft 90 provided with cams 109 for operating a shutter 68 through levers 110. When a note is inserted, it is gripped by the fast rollers 29, 30, and being pulled between the rollers 72, 73, it causes these to rotate. A cam 117 on the roller sleeve 27<A> then raises a spring-resisted arm 118 on a spindle 119 and causes an arm 104 on the spindle to operate the drawer-releasing rod 21. The loose rollers 72, 73 may be returned to their original positions against a stop by a spring. According to the Provisional Specification, an endless band or sliding shutter provided with clips draws all notes through one pair of rollers, the number of revolutions of which, being dependent on the length of the note inserted, determines which change drawer is released; an apparatus like that shown in Figs. 3 and 5 may similarly act with one set of rollers. Also, the machine may be arranged to exhibit the notes behind glass after they pass into it.
