Abstract: 2085. Boult, A. J., [Gill, E. R.]. Jan. 27. Receipts, checking and recording. -Relates to a hand or mechanically operated change-making machine which, in connection with a number of salesmen's instruments, deals out and despatches coins to salesmen at different stations and automatically prints a record of all change made and its destination. As the result of the selective operation o f a salesman's instrument and the depression o f corresponding keys in the central machine, the latter is enabled, during a cycle of motions, to eject the right coins and to print the amount ejected of each denomination. The changeexpelling device shown in Fig. 2, is operated from the driving -'shaft 21 by a crank and link connected to a swinging frame 27<a>, which, by pushing forward selected jointed slides 5, removes at each stroke the lowest coin from each of the piles standing in the particular coin cylinders 34 selected, the operative slides 5 being previously lowered into the path of the top rail of the frame 27<a> by intermediate hinged bars 3 through the falling of the corresponding slotted drop bars 6, Fig. 6, frictionally connected therewith. The distance these drop bars fall determines the various lengths of time the selected slides 5 remain down. Each drop bar may be pushed off its ledge either by a direct pusher 12, 13 or by any selected one of a number of intermediate bell-crank arms 14, 16, 18<b>, and may thus fall either the maximum distance or be caught at an intermediate position by a stud 15 on the arm 14. The lifting bar 38, elevated step by step by a Geneva-stop-controlled cam, by commencing to raise a depressed bar 6 returns the slide 5 at once to the inoperative position, and so terminates the dealing-out of coins of a particular denomination after a number has been ejected corresponding to the height of the bar 6 above its lowest possible position. The printing-mechanism is shown in Figs. 2 and 4. Each drop bar 6, in falling, rocks intermediate levers connected with a sector carrying a number of types. The sector 46, carrying types recording the station to which the changes are sent, is connected by a vertical slide bar and rocking-lever 90 with a cam 89 moved on at each revolution of an intermediate shaft 22. A swinging platen 47, over which travels step by step a band of paper, is carried on an arm 55 and brought down on the proper type opposite by a link 52, the free end of which rests normally on the ledge of a magnet armature, which, on being energized, drops the link so that a lug on the swinging frame may engage with a dog on its underside. The platen is set back at the return swing of the frame 27<a>, which first lifts the link on to its armature ledge and then moves it endways into the former position. The abovedescribed mechanism is placed at the disposal of each salesman in turn by a cam on the Genevastop-driven shaft 23 of the change-maker, which, in rotating, closes one line of switches after another, electrically connected with the respective salesmen's instruments. Each of the latter has keys 144, Fig. 33, for closing, by means of levers 142, breaks at 141 in the circuit of electromagnets, the armatures of which act on the selected dropbar pushes ; also a key for closing, by means of a lever 152, a change-maker motor circuit break 168, and also for closing a break 149 by bringing the left-hand end of the lever 152 into the recessed end of a slot 155 in a spring-controlled arm 154<a>; and, lastly, a key for raising again the above-named keys. When the change-maker motor is started by a salesman operating his instrument, it drives idly until the shaft 23, by rotating, closes the line of switches which place the respective instrument in operative connection with the rest of the machine. The circuit of which a break 149 was previously closed in the instrument is then ready to be completed by the next forward swing of the frame 27<a>, which comes against a suitably-placed contact on a disc rotating with the shaft 22. This circuit energizes an electromagnet, the armature of which introduces a shunt in the change-maker circuit. The circuit referred to also energizes an electromagnet 147, which causes a catch 159, Fig. 34, forming a bell-crank arm of the armature 157, to release another bell crank 160, the arm 161 of which finally closes a break in a second circuit. The latter has a branch passing from the contacts 141, Fig. 33, through the drop-bar-selecting electromagnets to the electromagnet which releases the recording-mechanism actuating-link 52, Fig. 4. This circuit is ready to be completed at the next swing of the frame 27<a>, and it then energizes a magnet 148, Fig. 33, the bell-crank armature 166 of which rocks the arm 154<a> and opens the break 149. For the rest of the change-maker's cycle of motions, the change ejector deals out coins which are finally guided into the proper change-carrying car and electrically despatched to the proper salesman's station.
