Patent GB-259069-A (GB)
Abstract: 259,069. White, A. E., (International Time Recorcding Co. of New York). Dec. 15, 1925. Computing - apparatus.-In a workmen's time recorder of the individual card - type means are provided whereby a plurality of elapsed times on a number of different jobs is recorded on a single card and a record obtained of the total of the several elapsed times. The card 1 shown in Fig. 25 is marked with columns representing hours and tenthsof hours distinguished bv horizontal rows and when inserted at the beginning of the day and the machine is operated has a section 2 cut from its edge and holes 3, 4 punched in the zero positions in the rows and the corresponding time stamped in the righthand column. After the completion of the job the card is again inserted and the machine operated whereupon a section 5 is cut, holes 6. 7 are punched, and the elapsed time is stamped. Assuming the workman starts on a second job, he inserts his card at the completion thereof and effects the record represented by the punch holes 8, 9. If this job finishes at the noon interval the holes 10, 11 punched after the resumption of work will occupy the same relative position as the holes 8, 9. A record of other jobs will be produced as shown and finally a total of the elapsed times may be printed by the depression of a total-taking key. The operating handle 17, Fig. 1, drives a main cam shaft 18 and is provided with a full stroke sector 24 and pawl 27. A cam 19, Fig. 19, on the shaft 18 actuates a lever 20 and bell crank lever 21 to force a bar 22 against the cutter 15 for clipping the edge of the card. A second cam 29, Fig. 2, actuates a bell crank lever 30 to reciprocate a sliding frame 33 carrying a pair of pin barrels 34, 35 adapted to actuate a pair of punches 49, 50 arranged in two rows of ten. The barrels 34, 35 are actuated by the energization, every six minutes from a master clock, of an electromagnet 42 the armature 41 of which through segmental gears 39, 40 and a pawl 36, Fig. 15, operates a ratchet wheel 43 on the spindle of the barrel 35, transfer to the barrel 34 being effected by a cam 44, arm 45, arm 45<c>, pawl 46, and ratchet wheel 48. The pawl 46 is maintained in engagement with the wheel 48 by a spring 45<d> connecting an arm 46<a> of the pawl 46 to an extension 45e of the arm 45<c>. The time represented by the position of the pin barrels is indicated on drums 56, 57, Fig. 6, the drum 56 being actuated by a pawl pivoted to the armature 41 of the electromagnet and the movement transmitted to the drum 57 by any known form of transfer mechanism. Type wheels 63 are provided to record the zero time and subsequently the elapsed time, each of the wheels engaging a corresponding rack 75, Fig. 3, carrying a pinion 74 in gear with a pair of differentially movable rack bars 70, 73, the rack 70 of which is operatively connected through segments 69, 66 to an actuating segment 65 on the main shaft 18. Pivotally connected to each of the racks 75 is a corresponding arm 76 operated by a bell crank lever 77 engaging a cam 78 on the main shaft. The movement of the racks 73 is controlled by the operation of pawle 117 in accordance with the last previous perforations and that of the racks 70 by the operation of pawls 114 in accordance with the current time. The impression rod 64, Fig. 3, is operatively connected to a cam on the main shaft. The pawls 114, 117 are operated by electromagnets 111, 116 in circuit with contacts of a selector device 84, 84a under the control of contacts 60 associated with the time-indicating drums 56, 57, and contact pins in the card. The drums each carry a contact 92, 93 for co-operation with the punched holes arm 60 for co-operation with a contact ring 61 and a set of ten contacts 62 as shown in Fig. 26. The selector devices 84, 84a, Figs. 2 and 18, each comprise two sets of insulated contacts 85, 86 and rings 83<c>, 83<g> and a rotatable contact arm 83 operated by a pinion and sector 82 connected by a link 81 to a bell crank lever 80 engaging a cam 79 on the main shaft. The pins 92, 93, Fig. 2, which are arranged in sets of ten for the hours and tenths of hours, are adapted to make contact with a plate 94 mounted on the opposite side of the card-holder 14 and pass through the perforations presented thereto when the shaft 132<a> carrying the pins is rocked by an arm thereon operatively connected to the main shaft. Additional rows of pins 95, 96 are provided for use in total-taking operations these being arranged at the lower end of the card-holder. The contacts 62, the selector devices 84, 84<a>, and the sets of pins 92, 93, 95, 96 are connected to groups of contacts 87 - - 91, 87a - - 91a, as shown in Fig. 26, the contacts 88, 90 and 88a - - 90<a> of these groups being movable under the control of an arm 124, Fig. 2, of a shaft 123. Total-taking mechanism. When a total of the elapsed time is to be printed a push-rod 120 is depressed to lower an arm 122 to rock the shaft 123 thus transferring the movable contacts 88, 90, 88a, 90<a> from their normal engaging position with contacts 87. 89, 87a, 89a to a position to engage contacts 89, 91, 89<a>, 91<a>. At the same time a pin 133, Fig. 20, on the push-rod 120 to which the arm 22 is pivoted is lowered from engagement with a projection 134, Fig. 19, on the cutter 15 and the cutter is retracted by a spring to an inoperative position. The card is then permitted to fall to the bottom of the cardholder. A bifurcated projection 125, Fig. 1, on the push-rod engages a pin on an arm 126 and when the push-rod is depressed actuates through a link 127 and arms 128, 131 a link 132 to lower the support 132a of the pins 92, 93. The support is arrested by the engagement of an arm 137, Fig. 21, with the clipped portion of the card, a spring-actuated pawl 136 integral therewith being rocked to engage a tooth of a fixed plate 138. The pins 95, 96 which are mounted on a shaft 141 are rocked to engage the contact plate 94 by an arm 140 engaged by a pin 139 on the push-rod. In this operation the first holes punched in the card determine the amount of movement of the differential rack-bars 73 and the last two holes punched control the positioning of the rack-bars 70. Specification 24178/11 is referred, to.
