Abstract: 4178. Chiger, S. Feb. 18. Money-delivering apparatus. - In machines for providing and indicating change, ratchetwheels or the like are coupled with the controlling-drums and the number wheels for the change, and are released, when the amount received is at least one decimal greater than amount to be paid, to allow recoil springs to return them through one-tenth of their periphery to position the ejector-controlling drums properly. Arrangements are also provided for throwing-in alternative ejectors when any coin tube is empty. Under apertures 2, 3, 4 in the casing 1, Fig. 3, are sets of wheels 9, 14, 19 for indicating the amount received, the amount to be paid, and the change, respectively, each set comprising wheels for pfennig units and tens, mark units and tens, and mark hundreds. Each number wheel carries a toothed wheel 50 driving a wheel 52, which has type projections 53 for printing corresponding numbers on a moving paper band 54. They are mounted on concentric hollow shafts, and driven by chains from five groups of chain wheels 56 ... 75, Fig. 1, the first wheel of each group driving the " amounts to be paid wheels " 14, the second the " amounts received " wheels 9, and the fourth the " change " wheels 19, the third wheel of each group driving the wheels 120-124 on a shaft 96. The wheels 57, 61, 65, 69, 73 are freely rotatable on a shaft 55, and are connected to toothed wheels 74<1>, 75<1>, 76, 77, 78 gearing with toothed segments 85 carried by hand levers 80-84 carrying pointers 90 moving over scales numbered 0-10, on the casing wall. The first and third chain-wheels of each set are freely and displaceably mounted on the shaft 55, and are grooved to receive forks 92 on a longitudinally movable rod 93. They may be alternately coupled with the second wheels by clutch teeth 94. The wheels 58, 59, and the corresponding wheels in other sets, are coupled by teeth 94 and normally held together by springs 95, the teeth allowing movement of the wheel 58 in one direction without moving the wheel 59. The chain-wheels 120 ... 123 drive drums 97 ... 100 connected thereto against their springs 118. These drums have rings of teeth 101 ... 107, each adapted to engage the arm 108, Fig. 4, ot pivoted two-armed levers, the arms 108, 109 of which are flexibly connected at 111. The arms 108 rest on spring-pressed pins 112, and have pawls 114 to act in one direction only. The wheels 120 ... 124 are each connected to toothed wheels 125 and ratchet-wheels 126, and have contact pins 127 engaging with stops 129 to limit the movement of the drums. The wheels have 30, and the ratchets 10, teeth. With each of the ratchets engage three spring pawls 131, 132, 133, one-third of a tooth space apart. lifted by a two-armed lever which is operated by a cam 138 on a shaft 139 driven from the till handle. Each toothed wheel 125 is engaged by a spring pawl 145 on a slide 144, connected by a spring piston and small cylinder with a lever 148 operated by a three-prong cam on the shaft 139 to reciprocate the slide 144 and turn the wheel through one step. A similar slide 156 engages each ratchet-wheel 125, and is driven by gearing from the rod 93, which is operated by a handle 166 and returned by a projection 167 on a wheel 168 driven from the handle. The ejecting-slides 169, which may be superposed, have coin apertures 170 having extensions to receive a guide and stop-pin on the casing. Each ejector is connected to a rod 174 having annular contractions 175, 176. The rods pass through apertures 177 in bars 178 surmounted bv riders 179 seated beneath the pins 112. Each rider has a slot narrower at its upper end to pass on to the contraction 175 and couple the riders 179 with the rods 174. As shown in Fig. 4, the riders rest on similarly slotted anglepieces 185, supported by springs 187 on rods 188 adapted to be held down when depressed by spring-pressed grippers 209 engaging recesses 213 in the rods 188, the grippers being carried in supports attached to bars 178. A spring 192 displaces the rod 174 to the left when the recess 170 contains no coin. The bars 178 are connected to cam-operated rods 196, the cam-shaft 139 also carrying cams to operate shaking-plates 203 The rods 196 are moved to release the grippers 209 by a lever 214 operated by a cam disk 217. A discharging-slide beneath the cointubes 173 has apertures 220', 221, the latter allowing coins carried forward by the ejectors to fall into the trough 226, while the former is for emptying the tubes when the slide is pulled forward. A spring-pressed yoke 223 is normally located in front of the slides, but may be pushed back and snapped into the apertures 221 for drawing out the slides simultaneously. Each rod 174 has a rod 227 carrying a pawl 228, which, when the rod is moved to the left when a tube is empty, raises a common stop-plate 230, which holds the connexion 111 from movement, to allow an idle movement of the levers 108. The plate is also connected to a rod 234 operated by a cam on the handle shaft to raise the plate when the handle is at normal position. The arms 109, on this idle movement, operate pawls 243 to turn a disk 246", Figs. 1 and 3, which has an angled slot, the third idle movement allowing a spring to move a handle 251 along the axial slot into the path of the operating-handle, which is thereby locked. To allow return of the ratchet-wheels through one-tenth of a revolution the levers 80, when they reach the "ten" divisions, operate against inclines 267 on levers 264 to move over the ends 265, which are depressed into grooves 262 on sleeves 256 when the corresponding chain - wheel leaves zero, whereupon a pin 278 is raised out of a hollow in a disk 279. The pin is connected to a lever which depresses the corresponding end 265. The sleeves carry three projections 257 to raise pawls 131. 132, 133 successively to allow the drum to turn back. The lever 80 acts on the sleeve corresponding to the drum of the next higher denomination, and the sleeves are clutched to members 261 against springs 260. The shaft 255 is rotated, by a toothed wheel thereon engaging a segment 283, Fig. 10, on a lever 284, when a key 285 is inserted in the machine. Keys are provided for different salesmen, and are placed in the slot 287 and moved along slots 293, 294 in superposed plates 290, 291, until projections at the bottom fit into corresponding holes 295, 296 in a plate 292. The key can then be turned, as its blade then passes under a plate 298. In turning, the keys operate a bar 303 to turn a wheel 304 and withdraw a stop-pin from the path of the handle 142, and also to operate a bell-crank lever 301 or 310 to turn a type-wheel to different extents, to show which salesman is operating. These levers remain until another key forces back a lever 321 connected thereto. The coins are fed to the tubes by slides 334 reciprocating under the insertion apertures. The slides push the coin over a hole 335 large enough to admit small coins, and against a bridge 339 low enough to push genuine coins into a hole 336, but high enough to allow thin ones to pass to the hole 337. The coins falling down the hole 336 are conveyed by a slide 340 to the tubes through a closing-member held by a pawl. Slides 334, 840 are reciprocated from a shaft 353, Fig. 1. A signal 356 raised by the movement of the bar 227 rises behind an aperture when a tube is 1 empty. A counting-pawl counts the number of coins fed to the tube. In operation, if a purchaser has to pay 15 marks and tenders 20 marks, the salesman moves levers 82, 83 to indicate 15 on the number-wheels. He then pushes the rod 93 to reverse the chain-wheel couplings, and by means of the rack-bar 165, turns the drums forward through one-tenth to zero. The levers 82, 83 are then moved to indicate 20 on the number-wheels now in gear. The hand-lever 82 also puts its sleeve 256 into gear. The change-wheels now show 15 marks, while the drums 100 are turned one step and the drums 99 five steps. The key is now inserted and the handle 142 unlocked. The lever 284 turns the shaft 255 and the drum 100, and the connected change-wheels are turned back through one step by release of the pawls 131, 132, 133 to leave only five marks as change. The handle 142 is then turned. The projection 167 then returns the bar 93 to disengage the numberwheels, The inserted coins are then fed to the tubes 173, and the slides 174 shaken. If there is no five-mark piece, the stop 230 is raised, and the cams 163, 154, 155 successively turn the wheel 125. The first step brings the teeth of the drum on to levers 108 corresponding to a three and a two mark piece respectively. Failing them, a second step operates the levers of five one-mark tubes, while the third step releases the handle 251 by means of the pawl 243, and locks the machine. When a lever 108 is depressed, it forces down the corresponding pin 112 and rider 179, and couples the slide 174 with the bar 178 to eject the coin. The gripper 209 holds the angle-piece down until released by its cam. The pawls 131, 132, 133 are then released by the lever 135 to allow the drums to return. Levers 327 operated by cams 328 hold the chainwheels uncoupled during the movement of the levers 108.
