US3576322A — Card-feeding apparatus

Claim 1

Independent Claim 86 words

Apparatus for feeding cards sequentially from one end of a stack of cards comprising: a feed roll; means for mounting said roll so that it may be moved toward the card stack to exert a force on the stack; and drive means for moving said roll toward said stack as aforesaid and for initiating rotation of said roll about its own axis after the roll has completed its movement toward said stack for thereby displacing a card at the end of a stack from the stack.

Claim 2

Dependent Claim 86 words

Apparatus for feeding cards sequentially from one end of a stack of cards comprising: a feed roll; means for mounting said roll so that it may be moved toward the card stack to exert a force on the stack; and drive means for moving said roll toward said stack as aforesaid and for initiating rotation of said roll about its own axis after the roll has completed its movement toward said stack for thereby displacing a card at the end of a stack from the stack.

Claim 3

Dependent Claim 68 words

Apparatus for feeding cards as set forth in claim 1, said mounting means including a pivotally mounted arm carrying said roll for pivotal movement and said drive means including a second roll and a friction belt extending around said rolls and moved by said feed roll into frictional contact with a card on the end of the stack as said feed roll moves toward the stack as aforesaid.

Claim 4

Dependent Claim 61 words

Apparatus for feeding cards as set forth in claim 2, said arm being mounted on the axis of rotation of said second roll and the apparatus further comprising a friction brake effective on said feed roll so as to hold said feed roll stationary from rotation about its own axis until said feed roll has completed its movement toward said stack.

Claim 5

Dependent Claim 95 words

Apparatus for feeding cards sequentially from one end of a stack of cards comprising: a roll; a pivotally mounted arm carrying said roll so that the roll may be moved toward the card stack to exert a force on the stack; and means for applying a tangential force on said roll tending to rotate the roll so that said arm is pivoted due to said tangential force and said roll is rotated about its own axis when exerting force on the card stack so as to displace the card at the end of the stack.

Claim 6

Dependent Claim 95 words

Apparatus for feeding cards sequentially from one end of a stack of cards comprising: a roll; a pivotally mounted arm carrying said roll so that the roll may be moved toward the card stack to exert a force on the stack; and means for applying a tangential force on said roll tending to rotate the roll so that said arm is pivoted due to said tangential force and said roll is rotated about its own axis when exerting force on the card stack so as to displace the card at the end of the stack.

Claim 7

Dependent Claim 64 words

Apparatus for feeding cards as set forth in claim 4, and further comprising a friction brake effective on said roll so that said roll is moved to exert a force on the stack when stationary on its own axis and is subsequently rotated about its own axis when said friction brake yields so as to displace the card at the end of the stack.

Claim 8

Dependent Claim 146 words

Apparatus for feeding cards sequentially comprising: a hopper for holding a stack of cards; a feed roll; a pivotally mounted arm carrying said roll so that the roll may be moved toward one end of the card stack; a second roll; a friction belt extending around said rolls and movable with said feed roll toward one end of the card stack so that the belt engages a card on the end of the stack; and means for drivingly rotating said second roll so that said feed roll is moved toward said stack to cause said friction belt to engage a card on the end of the stack and said feed roll is subsequently rotated about its own axis and said friction belt is correspondingly moved about said rolls when in contact with the card at the end of the stack so as to displace the card.

Claim 9

Dependent Claim 146 words

Apparatus for feeding cards sequentially comprising: a hopper for holding a stack of cards; a feed roll; a pivotally mounted arm carrying said roll so that the roll may be moved toward one end of the card stack; a second roll; a friction belt extending around said rolls and movable with said feed roll toward one end of the card stack so that the belt engages a card on the end of the stack; and means for drivingly rotating said second roll so that said feed roll is moved toward said stack to cause said friction belt to engage a card on the end of the stack and said feed roll is subsequently rotated about its own axis and said friction belt is correspondingly moved about said rolls when in contact with the card at the end of the stack so as to displace the card.

Claim 10

Dependent Claim 59 words

Apparatus for feeding cards as set forth in claim 6, and further comprising a friction brake for said feed roll to cause the pivoting movement of said arm to take place prior to rotation of said feed roll about its own axis and corresponding movement of the friction belt to displace a card at the end of the stack.

Claim 11

Dependent Claim 31 words

Apparatus for feeding cards as set forth in claim 7, said driving means for said second roll including a drive shaft, and said arm being pivotally mounted on said drive shaft.

Claim 12

Dependent Claim 30 words

Apparatus for feeding cards as set forth in claim 8, said friction brake comprising a washer and a spring for holding said washer in pressure contact with said feed roll.

Claim 13

Dependent Claim 52 words

Apparatus for feeding cards as set forth in claim 8, and further comprising means for limiting the pivotal movement of said arm and of said feed roll and spring means for moving said belt out of engagement with the card at the end of the stack when driving of said shaft ceases.

Claim 14

Dependent Claim 105 words

In a method of feeding cards sequentially off the end of a stack of cards, the steps which comprise, applying a tangential force to a friction faced roll which is rotatable about its own axis and which has its axis constrained to move in a circle, and yieldably braking said roll from rotation on its own axis so that said tangential force initially moves said roll to exert a force on the end of the stack of cards and so that said roll subsequently overcomes the braking force to rotate about its own axis to thereby displace the card at the end of the stack.

Claim 15

Dependent Claim 105 words

In a method of feeding cards sequentially off the end of a stack of cards, the steps which comprise, applying a tangential force to a friction faced roll which is rotatable about its own axis and which has its axis constrained to move in a circle, and yieldably braking said roll from rotation on its own axis so that said tangential force initially moves said roll to exert a force on the end of the stack of cards and so that said roll subsequently overcomes the braking force to rotate about its own axis to thereby displace the card at the end of the stack.
