Patent GB-287243-A (GB)
Title: Improvements in and relating to machines suitable for checking or verifying mechanical records for use with statistical, calculating and like machines
Filed: 1926-12-18
Abstract: 287,243. Power, R. F., Thomas, A., and Accounting & Tabulating Corporation of Gt. Britain, Ltd. Dec. 18, 1926. Verifying cards. - Mechanism is provided for verifying a sequence of unlike perforated cards, the values of the perforations in the columns used increasing or decreasing by a predetermined amount from card to card. If the sequence is incorrect or incomplete the machine is stopped or a distinguishing card (e.g. a coloured card) is inserted among the record-cards. The sensing may be mechanical, electrical, or pneumatic. Fig. 3 shows a construction which verifies cards having a perforation in one column of the same value as the perforation in the next column of the next card. For instance, an article being manufactured has a cost card for each department through which it passes; each card is punched in two columns, the figure in the first column representing the department to which the card corresponds and the figure in the second column the department from which the article came. Thus if the cards are stacked in order of the departments the figure in the second column of any card should be the same as the figure in the first column of the preceding card. Coacting with the two columns are a row of sensing pins 106 and a second row 106<1>, each pair 106, 106<1> co-operating through links 114, 114' and bellcranks 115, 115<1> with a disc 118 which makes one revolution in the card cycles. Each disc has two pawls 124 pivoted at 125 and having fingers 126 which may be projected beyond the edge of the disc; the pawls being retained in position by spring detents 132. If the cards are correctly arranged they should in succession be perforated, say, 2,1-3, 2-4, 3-5, 4, &c. On reading the third card, say, the pins 106, 106<1> will cause the fourth right-hand lever 115 to project a finger 126 of the " 4 " disc and the third left hand lever 115<1> to restore a finger 126 of the " 3 " disc. At the next card-perforated 5, 4- the projected finger 126 of the " 4 " disc will be restored and the right hand finger of the " 5 " disc will be projected. Thus the fingers 126 of the successive discs are projected and restored in turn. But if the sequence is incorrect or broken a finger 126 remains projected and in moving with the disc rocks an arm 141. which motion is utilized through linkage to feed a coloured card among the record-cards at the point where the sequence is incorrect. In a modification, Figs. 4 and 5, the cards run in the sequence 0, 1, 2. 3, 4 &c. only one card column being used. For this one row of pins 106 is connected by links 166, 167 to bell-cranks 115, 115<1> of adjacent discs 1181; the levers 115 for the "0" and " 9 " positions are rigid with a shaft 168 to complete the cycle, the remaining levers 115 being loose on this shaft. As in the previous construction the fingers 126 of the successive discs are projected and restored in turn if the sequence of cards be correct.
