Claim 1
Independent Claim
182 words
A wicket for holding a stack of flat flexible articles provided with paired holes to accommodate wicket leg members, which articles are to be removed one at a time from the stack, said wicket comprising, in combination, a. a bearing member adapted to transmit a vertical restraining force in combination with an edge restraining member to said stack and having a horizontally extending span greater than the linear distance between the paired holes plus two hole diameters, b. an article edge restraining member attached to and extending from said bearing member adapted to maintain a portion of an edge of each topmost article in the stack in a substantially flat horizontal disposition as each successive topmost article is forcibly removed from the stack, c. wicket leg members extending vertically each respectively through the holes in the stack of articles, adapted to hold individual articles therein in substantially registering relationship, said wicket leg members having ends adapted to extend into wicket mounting means and, d. upwardly extending shoulder members disposed between respective uppermost ends of said wicket leg portions and said bearing member,
