Abstract: 166,595. Bailey, R. D. Oct. 10, 1919. Money-delivering apparatus.-In apparatus for changing Treasury and like notes, the note is inserted between a driving-roller which may be rotated by a handle, or a slide which may be positively reciprocated, and a driven roller which is separated from the driving-roller or the slide by about two-thousandths of an inch, so that it is only driven from the driving-roller or slide when a note is inserted between them. The driven roller is thus rotated to an extent corresponding to the size of the note inserted, and actuates mechanism effecting the release of the corresponding change drawer, which may then be opened, permitting the extraction therefrom of the lowest of a series of receptacles each containing change for a note of that value. The spindle of the driving-roller 42, Fig. 12, is carried by arms 18, 19. figs. 10 and 11, carried by side plates in which are mounted the spindle of the driven roller 40, the arms being sprung away from the bottom portions of the side plates by screws 46, 47, so as to adjust the distance between the driving and driven rollers. The apparatus is usually arranged for notes of two dencminations, a drawer and a magazine of change receptacles being arranged at each side of the machine, one for each denomination of note. The drawers are provided on their opposed sides with inclined recesses 80, 81, Fig. 9, and a sliding rod 79 is mounted between the drawers so that when one is opened the rod is driven by the inclined recess into the recess in the other diawer, thus preventing the two drawers from being open together. Instead of one magazine, two or more may be employed at each side of the machine, and made to revolve by the pushing in or pulling out of the change drawers. Two plates 77, 78 held together by screws form a guide for the notes, the plates being cut away to clear prongs 41 carried by the driven roller 40. When a note, for example, a 10s. note, is inserted and the driving roller rotated or the slide pushed in, the driven roller 40 is rotated by the note, and the 20s. cam 37, Fig. 10 on the spindle of the driven roller is rotated counter-clockwise. A lug 70 on the cam engages a heavy pivoted lever 53, known as an inertia-absorber, and raises a striker 64 which in its fall strikes a bell 66, the prongs 41 having reached a position in which they prevent another note from being inserted. The 10s. cam 38, Fig. 11 on the opposite side of the machine will now have reached such a position that it will have depressed a pivoted catch 32 and released an angular lug 30 on a plate 23 attached to the 10s. change drawer, permitting the drawer 21, together with the lowermost change receptacle, to be pulled out. As the drawer 21 is pulled out, the plate 23 fixed thereto engages a lug 71 on the cam 38 and further rotates the cam 38 and with it the 20s. cam 37, first arriving the position shown in Fig. 14. In this position the operator is unable to close the drawer 21, since the lug 30 is unable to depress the catch 32. The other drawer 20, although its catch 31 is in position to release the corresponding lug 29. is held locked by the rod 79 in the recess 80. When, however, the drawer 21 is pulled out to the limit of its position, the cam 38 is further rotated and the catch 32 depressed so that, on closing the drawer 21, the lug 30 rides over the shoulders of the catch 32 and the whole mechanism is once more in its zero position, the last part of the rotation of the cam 38 corresponding with a rotation of the 20s. cam 37 which depresses the catch 31 so that it again locks the lug 29 on the drawer 20. The prongs 41 have also been rotated to a position which allows the insertion of another note. Similar operations follow the insertion of a 20s. note. The inertia absorber 53 is provided for preventing a 10s. note being raced through the apparatus so as to spin the cams past the 10s. release position to the 20s. release position, the lug 69 of the 20s. cam 37 coming into contact with the absorber 53 which takes up the inertia of the rotating cams, roller &c. The lugs 69, 72 also prevent the cams &c. being spun past their proper positions by the hasty pulling out of the drawers, and the lugs 69 - - 72, ensure the apparatus being returned to zero position when the drawers are pulled out. The lug 69, by coming into contact with the bottom of the arm of the inertia absorber, prevents the cams from being rotated backwards. The prongs 41 prevent the insertion of a long strip of paper and the withdrawal of same after extracting change, and also prevent the passage of a note into the apparatus without the operation of a change drawer. Where a slide 84, Fig. 19, is employed instead of a driving roller, a small angular recess 87 in the slide facilitates the insertion of the note between the slide and the driven roller 40.
