Abstract
Abstract A card feeder that relies upon an actuator such as a rotary solenoid to impart intermittent driving force to a feed wheel which underlies a deck of cards. Forward motion of the feed wheel moves a card from the deck forwardly until it is engaged by transport wheels which move the card to the next working station. A velocity governor is provided for limiting the maximum velocity of the shaft and the feed wheel during response to energization of the rotary solenoid.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
Apparatus for feeding cards from a deck comprising a shaft, a rotary solenoid connected to said shaft for intermittently reciprocating said shaft about its longitudinal axis, a feed wheel supported by said shaft for frictional engagement with the end card in a deck of cards, bearing means disposed intermediate said feed wheel and said shaft, said bearing means being operative to drivingly connect and disconnect said shaft and said feed wheel in response to the direction of rotation of said shaft so that during one portion of said reciprocating movement said wheel is driven by said shaft to feed said card, a velocity limiter wheel supported by said shaft, means for driving said velocity limiter wheel at a substantially constant velocity, and second bearing means disposed intermediate said velocity limiter wheel and said shaft, said second bearing means being operative to limit the velocity of said shaft when said shaft and said velocity limiter wheel rotate in the same direction.
Claim 2
Dependent Claim
160 words
Apparatus for feeding cards from a deck comprising a shaft, a rotary solenoid connected to said shaft for intermittently reciprocating said shaft about its longitudinal axis, a feed wheel supported by said shaft for frictional engagement with the end card in a deck of cards, bearing means disposed intermediate said feed wheel and said shaft, said bearing means being operative to drivingly connect and disconnect said shaft and said feed wheel in response to the direction of rotation of said shaft so that during one portion of said reciprocating movement said wheel is driven by said shaft to feed said card, a velocity limiter wheel supported by said shaft, means for driving said velocity limiter wheel at a substantially constant velocity, and second bearing means disposed intermediate said velocity limiter wheel and said shaft, said second bearing means being operative to limit the velocity of said shaft when said shaft and said velocity limiter wheel rotate in the same direction.
Claim 3
Dependent Claim
84 words
Apparatus for feeding cards from a deck comprising feed wheel means supported for frictional engagement with an end card of a deck of cards, means for causing said feed wheel means to intermittently rotate thereby feeding such end card from said deck, means coupled to said feed wheel means for limiting the velocity of said feed wheel means to a predetermined maximum, and said last named means being operative to engage said feed wheel means when said feed wheel means exceeds said predetermined maximum.
Claim 4
Dependent Claim
84 words
Apparatus for feeding cards from a deck comprising feed wheel means supported for frictional engagement with an end card of a deck of cards, means for causing said feed wheel means to intermittently rotate thereby feeding such end card from said deck, means coupled to said feed wheel means for limiting the velocity of said feed wheel means to a predetermined maximum, and said last named means being operative to engage said feed wheel means when said feed wheel means exceeds said predetermined maximum.
Claim 5
Dependent Claim
70 words
Apparatus as defined in claim 2 wherein said feed wheel means includes a shaft, said shaft being supported for intermittent reciprocation about its longitudinal axis, means for intermittently reciprocating said shaft, a feed wheel supported on said shaft and being fixed to said shaft during the first portion of said reciprocation to feed said end card, and being rotatable relative to said shaft during the second portion of said reciprocation.
Claim 6
Dependent Claim
56 words
Apparatus as defined in claim 3 wherein said velocity limiting means comprises a rotatable member mounted on said shaft, said rotatable member being driven at a predetermined speed, and means intermediate said velocity limiting means and said shaft for limiting the velocity of said shaft so that it cannot exceed the velocity of said rotatable member.
Claim 7
Dependent Claim
38 words
Apparatus as defined in claim 4 including card transport means for receiving said end card from said feed wheel and being operative to move said card at least the speed it is driven at by said feed wheel.
