Abstract: 1,183,336. Dispensing apparatus. RCA CORP. 20 April, 1967 [20 April, 1966]. No. 17249/66. Heading G4X. A dispensing apparatus comprises (a) a customer account card data reader; (b) an input device for entering a private identification number; (c) a memory responsive to the output of one of (a) and (b) for producing a corresponding identification number or account card data respectively; (e) means for comparing the so produced number or data with respectively the output of (b) or (a), and means for permitting dispensation by the apparatus subject to agreement between the compared numbers or data. In the embodiment of Fig. 1 which shows a currency dispensing apparatus the memory 16 stores customer account numbers, and the corresponding private numbers. Upon being addressed by the output of the reader 12 which reads a customer account number from an account card 10 the memory transfers the corresponding identification number to a comparison unit for comparison with the output of the input device 18. Information entered into the device 18 is indicated on a display 22 to enable a customer to check his entry. Upon there being an identity between the outputs of the memory and the input device the comparison unit causes a blank check to be supplied to a punch mechanism in unit 26. Information transmitted from the reader 12 and/or memory 16 is entered by the punch mechanism on the check, which is then dispensed for signing by a customer. The check is reinserted into a punch 30. The amount required is entered into device 34, and coded information designating that account is transferred on to the check by the punch upon pressing key 36. The check then passes to a reader and stacker 40, the output of which actuates a unit 42 to dispense the money, and which may update information, e.g. customer's account or number of checks cashed during a given time, in the memory 16. The apparatus may have only one input device and one punch for performing respectively the two manual inputs and the two punching operations. The checks, instead of being punched, may be printed or have information entered thereon in magnetic form. The checks may pass directly from the unit 26 to the reader and stacker 40 if signing is unnecessary. Alternatively if no checks are used the unit 26 and reader and stacker 40 may be omitted. In another embodiment a digital computer combines the unit 14 and memory 16, and conventional checks are inserted into a recorder and stacker. A sequencing number is printed on the inserted check. This number is also recorded on an auxiliary storage unit in which is recorded the amount withdrawn.

Filed: 1923-07-05
Abstract: 222,577. Berry, G. W., and Berry Hinge, Ltd. July 5, 1923. Addition to 164,408, [Class 83 (iv), Metals, Working]. Hinges.-In forming and assembling hinges of the flat or plate type by feeding pairs of blanks in separated paths through a series of pairs of dies to form a pintle on one blank and slots adjacent thereto, and to form bulb extensions on the other blank and thereupon to pass the extensions through the slots and turn them over, as described in the parent Specification, one set of blanks are transferred transversely in turn to the assembly position by a feed finger which is carried forward by a slotted member, then retracted and then released therefrom. The final feed finger a is slidably mounted on the longitudinally reciprocated feed bar a<3> and is provided with a pin b', which towards the end of the forward stroke of the bar a<3> passes into a slot b<2> in a member b fixed to a slide c reciprocated in guides c<1> by a cam through a spring-pressed lever and adjustable pivoted screw spindle d<1>. The feed finger is thus moved slowly forward transversely to transfer the blank x to its assembly position and is then quickly retracted beyond its normal position, whereupon during the backward stroke of the bar a<3> it is withdrawn from the slot and moves clear of the next blank. It then moves slightly forward to engage the next blank, the slide c at the same time moving slightly forward so that the pin b<1> may engage the slot b<2> at the end of the next forward stroke of the bar a<3>. The feed finger has a spring catch g engaging a notch g' in its guide so as to hold it against accidental movement. In order to prevent damage to machine parts such as the feed fingers should the blanks jam beneath or in their passage to or between the dies, the upper die head j has a wedge member k, which, if the feed fingers are not retracted, engages on its downward stroke, wedges k<1> on the feed finger slides h<1> on the bar a<3> to push them back clear of the dies. If the finger slides are not interconnected a separate wedge for each slide is used, but if the slides are connected together, as by bell cranks and connecting rod a single wedge only need be used.
