Abstract: 150,021. Phillips, F. April 28, 1919. Type-wheel machines; key interlocks; hammerimpression arrangements; web-feeding arrangements; line-spacing mechanism; ink-ribon mechanism.-Relates to change-giving apparatus in which sets of coins or notes, each set having a total value equal to that of some coin or note of higher value, are arranged in compartments of one or more carriers from which they may be obtained by one or other of a number of assistants, the name or initial of the assistant and other necessary particulars of each operation being recorded by the apparatus. The sets of coins or notes are carried in compartments 66 in a rotary carrier, one set in each compartment, the carrier being rotated through a distance corresponding to one compartment at each operation of a handle 91. This handle is normally locked, and can be set free by the action of any one of a series of keys 1 - - 4, each of which is intended to be actuated by one of the assistants who use the apparatus. The depression of any key effects the selecting operation for a printing device for recording the initial or other identification mark of the assistant actuating the key. Where more than one change carrier is employed, only one compartment of one change carrier may be emptied at one operation of the machine. A printing-wheel geared to the change carriers shows which compartment was emptied last... Printing-mechanism operated by the handles of the respective change carriers may be arranged to record the amount of change last abstracted from the machine. Each of the key spindles 20, Fig. 11, has on it a block with a projecting pin 23 which works in slots in a sliding plate 33. One of the slots 25 in which each pin works is inclined, and the other, 42, is vertical, all the inclined slots being of the same inclination. Thus, whichever of the keys is depressed, the plate 33 is moved downwards to the same extent, the vertical slots preventing the motion of the plate 'being, interfered with by those keys which are not depressed. The blocks on the key spindles also have thereon pins 24, Fig. 10, which work in slots in a sliding plate 33. Each slot has a vertical portion 55, and another portion 56 - - 59 which is horizontal in the case of the first key and inclined in the case of the others, the third being more inclined than the second, and the fourth than the third, and so on. Thus, the plate 33 is depressed to a different extent according to which key is depressed, the vertical slots preventing the keys which are not depressed from interfering with the movement of the plate. An arm 154 is rocked by the motion of the plate and' the amount of the rocking determines the movement of a type sector 194 carrying the initials or identification marks of the various assistants. For printing a record, Fig. 20, of the compartment last emptied, the initial of the assistant, and the amount of change extracted, an inking ribbon 222, Fig. 16, passes between a paper strip 11 and the printing wheels 130 from the inking ribbon supply roll 223 to a receiving roll 224, studs 225, 226 being provided to keep the ribbon clear of the printing wheels. The roll 223 is supplied with braking means 228, 229, 230. The hammer 236, Fig. 19, is arranged between the hammers 234, 235, each of the latter being provided with a lip 256, 257, which, when either of these hammers is operated, engages under the hammer 236 so that it also is actuated. A milled head 233, or other known reversing means, is employed' for rewinding the ribbon on to the supply roll 223. In using the apparatus, one of the assistants depresses the initial key set apart for him. The first effect is for plate 33 to slide downwards and through lever 174 and arm 179 to retract pawl 181 and allow spring 153 to pull up rack 146 and reset the initial drum 16 in neutral or zero position. The plate 33 continues its downward movement until spring 46 presses stop 49 over plate 33 and locks the latter down and locks the initial key which was last pushed in. It also draws pawl 114 forward and unlocks a bar 111 which projects over the operating handles of the change carriers, and prevents their actuation until it has been unlocked by the depression of one or other of the keys. The plate 33 is also moved downwards to an extent depending on the particular key depressed. The arm 154 is rocked to a corresponding position and sets the initial type sector 194. Next the handle of the particular change carrier to give the desired change is actuated, a sliding bar preventing the actuation of more than one carrier at a time. The carrier having been moved through a distance corresponding to one compartment is locked in position. The type wheel 130 for recording which compartment was last emptied, which is geared to the rotating portion of the change carrier is rotated one step to place the correct type in the printing position. The drum 16 is locked, until a further initial key is pressed in, by the arm 186 releasing the arm 179 from the dog 177 to allow the pawl 185 to engage with the appropriate notch 190. The printing hammer 234 or 235 is next tripped and strikes the printing blow and causes the hammer 236 aLso to strike its printing blow. The paper strip 11 and the inking ribbon 222 are fed the distance of one line of printed matter by the pawl 216 and ratchet 215 and the gearing 229, 230, 228. During the return of the operating- lever which was lifted, the initial key which was depressed is reset by the pin 277 and pawl.
