Abstract

Abstract An improvement in a card transporting device of the type including a pair of coaxially mounted, continuously rotating discs, each having a number of card gripper assemblies, each cooperating with an assembly on the disc for receiving a card, transporting it to the bottom of a stack of cards and placing it there. Each assembly includes an upper jaw mounted on a member which is pivotably attached to the disc and urged about the pivot in a first direction by a spring, a lower jaw similarly mounted on another member also pivotably attached to the disc and urged about its pivot in the opposite direction so as to normally close the jaws with sufficient force to grasp a card. A cam follower is mounted on the upper jaw member and cooperates with a cam mounted stationary with respect to the disc for rotating that member against the force of its spring and opening the jaws to receive the card. A wiper member is further mounted on the upper jaw member for frictionally engaging and pulling into proper position the bottom card on the stack at the same time or before the grasped card is stripped from the jaws by frictional engagement with the stack bottom. According to the improvement, the lower jaw has a hook on its end so that when a card is being grasped the upper jaw member is in a position such that the wiper frictionally engages and positions the bottom card, but, when no card is being grasped, the upper jaw member is in a position such that the wiper misses the bottom card, thus avoiding unnecessary card wear and stack vibration.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 349 words
In a card transporting apparatus for receiving a card and transporting it to the bottom of a stack of similar cards having a carrier member adapted to move from a reception to a delivery position, a cam member mounted so as to move with respect to said carrier member and at least a single card gripper assembly comprising an upper jaw, an upper jaw member attached to said upper jaw and pivotably mounted on said carrier member, a first spring connecting said upper jaw member to said carrier member and urging said upper jaw member about its pivot in a first direction, a lower jaw, a lower jaw member attached to said lower jaw and pivotably mounted on said carrier member, a second spring connecting said lower jaw member to said carrier member and urging said lower jaw member about its pivot in a direction opposite to said first direction, stop means for limiting the rotation of said lower jaw in a direction opposite to said first direction, a cam follower member on said upper jaw member for engaging said cam member at said reception position so that said upper jaw member rotates in a direction opposite to said first direction to separate said upper jaw from said lower jaw and receive a card which rotates with said assembly to said delivery position at the bottom of said stack where it frictionally engages said bottom and is stripped from said upper and lower jaws, and a wiper member mounted on said upper jaw member for frictionally engaging the bottom card on said stack and positioning it with regard to said stack, the improvement wherein one of said jaws includes means for causing said upper jaw member to be in a first position as it passes said stack so that said wiper member engages said bottom card when a card is between said jaws and for causing said upper jaw member to be in a second position as it passes said stack so that said wiper member does not engage said bottom card wheN no card is between said jaws.
Claim 2
Dependent Claim 349 words
In a card transporting apparatus for receiving a card and transporting it to the bottom of a stack of similar cards having a carrier member adapted to move from a reception to a delivery position, a cam member mounted so as to move with respect to said carrier member and at least a single card gripper assembly comprising an upper jaw, an upper jaw member attached to said upper jaw and pivotably mounted on said carrier member, a first spring connecting said upper jaw member to said carrier member and urging said upper jaw member about its pivot in a first direction, a lower jaw, a lower jaw member attached to said lower jaw and pivotably mounted on said carrier member, a second spring connecting said lower jaw member to said carrier member and urging said lower jaw member about its pivot in a direction opposite to said first direction, stop means for limiting the rotation of said lower jaw in a direction opposite to said first direction, a cam follower member on said upper jaw member for engaging said cam member at said reception position so that said upper jaw member rotates in a direction opposite to said first direction to separate said upper jaw from said lower jaw and receive a card which rotates with said assembly to said delivery position at the bottom of said stack where it frictionally engages said bottom and is stripped from said upper and lower jaws, and a wiper member mounted on said upper jaw member for frictionally engaging the bottom card on said stack and positioning it with regard to said stack, the improvement wherein one of said jaws includes means for causing said upper jaw member to be in a first position as it passes said stack so that said wiper member engages said bottom card when a card is between said jaws and for causing said upper jaw member to be in a second position as it passes said stack so that said wiper member does not engage said bottom card wheN no card is between said jaws.
Claim 3
Dependent Claim 21 words
In an apparatus as in claim 1, the further improvement wherein said causing means in a hook on said lower member.
Claim 4
Dependent Claim 69 words
In an apparatus as in claim 2, the further improvement wherein said upper jaw member and said lower jaw member are pivotably mounted at different locations on said carrier member so that said upper jaw moves past said lower jaw when said lower jaw member is rotated against said stop means and said upper jaw rests on said hook when said upper jaw member moves past said reception position.
Claim 5
Dependent Claim 21 words
In an apparatus as in claim 1, the further improvement wherein said carrier member is a disc adapted to be rotated.
