Abstract: 264,224. White, A. E., (international Time Recording Co.). Oct. 13, 1925. Computing-apparatus.-In a machine for recording, the time spent on and the cost of a number of jobs performed by a number of workmen receiving variout rates of pay a plurality of sets of time-operated members is adapted to be connected to one or more counting mechanisms or to mechanism for controlling a set of perforating punches in accordance with the different rates of pay sc that when a workman, after setting the machine to his rate of pay, inserts his card at the beginning of a job the time of starting is printed and a set of numbers is marked or holes are punched. When the job is completed and the card is again inserted the time of stopping is printed and a different set of numbers is printed, or holes punched. the difference between the said numbers or perforated positions representing the cost of the job. The machine is controlled bv a master clock 225, Fig. 24, the escapement mechanism of which controls once per minute the co-operation of contact arms 228, 229 to close the circuit through an electromagnet 331 so as to govern the movement of a pendulum 236 of a master contact mechanism 226. This contact mechanism has three switch arms 237 - - 239 adapted to be closed momentarily by cams 240 - - 242 at intervals of six seconds, one minute. and ten minutes respectively so as to energize corresponding electromagnets 243, 246, 248 to close the switches 276 and energize the electromagnets 256. Each electromagnet is associated with a multiple contact set, Figs. 11, 12, comprising a sixty-toothed ratchet wheel 253 and a set of cam discs 255 with projections or teeth ranging from one to nine. When the armature 257 of the electromagnet 256 is attracted it raises the pawl 260 so that a lateral projection 261 thereon rides over a pin 264 on a locking arm 262. At the same time a link 270 connected to the pawl carrying arm 259 rocks a shaft 268 to bring the contacts 267 on to the discs 255 the circuit through the contacts being completed if a projection on any of the discs is presented to it. The contacts are connected as shown in Figs. 24, 24<a>, to bus bars 273 co-operating with five bus bars 280 designated A - - E and connected respectively to corresponding electromagnets 125, one for each of five different rates of pay, through switches 281 - - 283 and electromagnets 287 - - 289. The bars 280 are mounted as shown in Fig. 17, on an insulating plate 292 and the bars 273 pass across them out of contact but are adapted to be connected therewith by means of screws 294 threaded through holes in the bars 273 the position of the screws depending on the rate of pay Each electromagnet 125 is associated with a rate computing unit 100, Fig. 2, and through a pawl lever 121 on the armature spindle 122 actuates a ratchet wheel 119, Figs. 9 and 10, on a spindle 117 interconnected with a spindle 116 by a spring 118. The spindle 116 carries a pinion 115 gearing with a pinion 114 on the uppermost spindle 112 of a set of spindles with a staggered arrangement of pegs 113, the several spindles 112 being progressively connected by transfer gearing of the Geneva type. The above described parts are mounted in side plates 103 slidably mounted on supporting plates 101 secured to the base of the machine. Movement of the plates 103 to permit the pegs 113 to operate punches 12 is effected by hooked members 132 operatively connected to the main handle 14 and engaging members 110 slidably mounted on the plates 103 the other end of the members 110 being connected to a three armed lever 106 pivoted to the plates 101 and connected by a toggle link 108 to the plates 103. The punches 12 are arranged in four rows of ten on a carriage slidable on a rail 3 and channel rail 5 and can be set to any one of the five different rate positions. The carriage is provided with a card holder 7 and has a pair of perforated plates 9, 10 through which the punches can pass. When the carriage has been positioned with the operating lever opposite the appropriate one of the five slots in the front cf the casing and the card inserted a start key 13 is depressed and a pin 16, Fig. 4, thereon rocks a lever 17 to limit the amount of insertion of the card so that the first, series of perforations is effected in the first. fourth, seventh, and tenth columns. At the end of a job the stop key 15 is depressed but has no action on the lever 17 so that the perforations appear in the third, sixth, &c. columns. The shafts 112 are, prevented from turning during the punching by means of a detent 133 engaging a star wheel 134 on the spindle 116 and if the magnet 125 is energized the energy will be stored by the spring 118 until the parts are released. The punches are restored by a plate 220 connected by a link 222, Fig. 5, to the main lever. The card is held in position by a pair of fingers 18<1> engaging its upper edge when either of the keys 13, 15 is depressed. A pin 22 on the key 13 actuates a lever to raise the bail 20 carrying the fingers 18' and a second pin 25 on the key engages a lever integral with the fingers to tilt them over the card. When the key 15 is depressed the bail 20 is not raised the fingers being tilted only. The keys 13, 15 ensure proper adjustment of the carriage by engaging holes 30 in the base plate and simultaneous operation of the two keys is prevented by a sliding member 31. The card em. ployed is shown in Fig. 21, and has a five hole space column lettered A - - E with a hole appropriate to the workman's rate of pay punched therein. Co-operating with this column are two sets of five sensing pins 150, 157, Fig. 6, and a special punch 136, Fig. 9. The punch 136 is operated by a projection 137 on a bar 138 when the plates 103 are reciprocated. The pins 157 are mounted in insulating blocks 141 and are actuated by a metallic plate 158 carried by and insulated from a bar 159 rocked about a shaft 160 by means of an arm 161, a link 162 and a slotted cam lever 163 engaging the pin 22 on the start key 13. The pin 157 that finds a hole in the card will engage a corresponding insulated contact plate 166 on the card carriage. Mounted on a bar 166 are five double insulated contacts 169. one for each of the different rates of pay, the upper portion of each contact engages a long contact bar 170 and the lower portion of each will engage a different one of the contacts 166. Current is supplied to the parts by brushes 171, Figs. 6, 23, on the card carriage slidable along insulated bars 172 on the bar 168, the circuit being completed by a bracket 173 on the start key closing contacts 174. When the card is inserted at the end of a job a special sensing pin 140, Figs. 9, 23, is presented to the perforation in the card made by the punch 136, this pin 140 being actuated by an insulated plate '142 on a bar 143 rocked by an arm 151 and link 152 from a slotted cam lever similar to the lever 163, the cam slot engaging a pin 155 on the stop key 15. The stop key 15 carries a bracket 175 which completes the circuit through contacts 176, pin 140 and the appropriate one of the pins 150. When the circuit through the contacts 174 or contacts 176 is completed a magnet is energized to unlock the operating lever, the movement of the armature rocking shaft 160<a> to free an arm 161a thereon from engagement with an arm 162a on the shaft 130. By this circuit arrangement the lever cannot be operated if the carriage is not set at the right rate-of-pay position since the contact 169 will be aligned with a contact 166 which differs from that engaged by the pin 157. If the stop key is depressed at the start since no hole corresponding with punch 136 exists in the card the pin 140 cannot complete the circuit. To record the time an electromagnet 180, Figs. 6, 23, is energized once a minute to actuate a bell crank lever 181 and thereby actuate a bell crank lever 182 carrying a pawl 184 operating a ratchet wheel 187 on a shaft 188 carrying a minute type wheel 189. Loose on the shaft 188 is an hour wheel 190 to which is fixed a ratchet wheel 191 actuated by means of a lever 102 and a cam 193 on the minute wheel. An endless inking ribbon 193<1>, interposed between the type wheels and card passes round a drum 194 and guide rollers 195, 196. On the opposite side of the card is an impression pad 198 carried by arms 199 fixed on a shaft 200. To the shaft 200 are secured other arms 201, Fig. 5, operatively connected to the main operating lever 14. Adjusting screws 205 are provided for regulating the pressure of the impression pad 198. The inking ribbon is fed by means of a pawl 212 carried by a lever 210 engaging a ratchet wheel 213 on the drum 194 and actuated by a link connected to a locking pawl 207 operated by the slide 110. The pawl 207 is adapted to engage a ratchet wheel 209 on the shaft 188 to hold the type wheels while printing is being effected. The shaft 188 carries a pinion 215 which gears with a pinion 216 on a shaft with universal connections to a clock 219 for displaying the time in agreement with the type wheels. A time controlled device for suspending the actuation of the mechanism during the non-working periods may be provided.
