Abstract

Abstract An apparatus for accepting a number of record cards and selectively feeding the cards, one at a time, to another station for operations such a reading and writing. In operation, an operator will insert the cards through an opening in the housing enclosing the apparatus. Beyond the opening in the housing is an expandable pressure throat made up of angularly extending wings integral with a rotatable card lifter and a rotatable pressure plate. With the stack of cards fully inserted and against a knife blade and guide, the stack is maintained intact by 1) a pressure roller connected to the pressure plate and forming part of the pressure throat, 2) card lifter rollers connected to the card lifter and forming another part of the pressure throat, and 3) the pressure plate itself forcing the stack against a baseplate carrying the card lifter. In the normal position a feed roller is spaced from the pressure roller, and is located on the same plane with the pressure and lifter rollers. The pressure plate is spring biased against the stack such that the stack is maintained intact in the vicinity of an exit throat and the entry throat. The feed roller is a continually rotating roller which is brought into contact with an outer card on the stack each time the card lifter is rotated. When this occurs, the outer card is ejected through the exit throat made up of an opening between the knife blade and a throat piece connected to the baseplate. Thereafter, the lifter is rotated back to its normal position and the cards are brought out of contact with the feed roller.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 187 words
An apparatus for accepting a number of cards and selectively ejecting said cards, one at a time, said apparatus comprising: a. a rotatable lifter means for normally acting against said number of cards adjacent one end of said number of cards and forming a part of an expandable pressure entry throat means; b. a base means for normally supporting said number of cards adjacent both an exit throat and another end of said number of cards and having carrying means for carrying said rotatable lifter means adjacent said expandable pressure entry throat means; c. a rotatable pressure means forming another part of said expandable pressure entry throat means; d. means for maintaining 1) said pressure means in contact with said number of cards adjacent both ends of said number of cards, and 2) said number of cards in contact with said base means and said lifter means; and e. means for causing said lifter means to bring said number of cards in and out of contact with a drive means adjacent said one end of said number of cards for ejecting one of said number of cards.
Claim 2
Independent Claim 187 words
An apparatus for accepting a number of cards and selectively ejecting said cards, one at a time, said apparatus comprising: a. a rotatable lifter means for normally acting against said number of cards adjacent one end of said number of cards and forming a part of an expandable pressure entry throat means; b. a base means for normally supporting said number of cards adjacent both an exit throat and another end of said number of cards and having carrying means for carrying said rotatable lifter means adjacent said expandable pressure entry throat means; c. a rotatable pressure means forming another part of said expandable pressure entry throat means; d. means for maintaining 1) said pressure means in contact with said number of cards adjacent both ends of said number of cards, and 2) said number of cards in contact with said base means and said lifter means; and e. means for causing said lifter means to bring said number of cards in and out of contact with a drive means adjacent said one end of said number of cards for ejecting one of said number of cards.
Claim 3
Dependent Claim 25 words
