Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 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 horizontally extending bearing member arranged and disposed to apply a vertical restraining force to said stack and having a bearing contact span length on the topmost article of the stack at maximum equal to the linear distance between the paired holes plus two hole diameters, b. leg members extending vertically through the paired holes in the stack each respectively adapted to maintain the individual articles therein and the holes in substantially registering relationship, said wicket leg members having free ends adapted to extend insertably into wicket mounting means, and c. shoulder members each having a first element connected to and extending upwardly from an end of the bearing member, a second element connected to and extending upwardly from an upper end of a leg member, and connecting means between the first element and the second element.
Claim 2
Dependent Claim
175 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 horizontally extending bearing member arranged and disposed to apply a vertical restraining force to said stack and having a bearing contact span length on the topmost article of the stack at maximum equal to the linear distance between the paired holes plus two hole diameters, b. leg members extending vertically through the paired holes in the stack each respectively adapted to maintain the individual articles therein and the holes in substantially registering relationship, said wicket leg members having free ends adapted to extend insertably into wicket mounting means, and c. shoulder members each having a first element connected to and extending upwardly from an end of the bearing member, a second element connected to and extending upwardly from an upper end of a leg member, and connecting means between the first element and the second element.
Claim 3
Dependent Claim
43 words
A wicket according to claim 1 wherein the horizontally extending bearing member is adapted to transmit a vertical restraining force to said stack and to bear on the topmost article of the stack for a total distance less than its overall horizontal span.
Claim 4
Dependent Claim
29 words
A wicket according to claim 1 wherein the horizontally extending bearing member, the leg members and the shoulder members are connectedly and integrally formed from a unitary rod-like element.
Claim 5
Dependent Claim
34 words
A wicket according to claim 1 wherein the horizontally extending bearing member has a bearing contact span length on the topmost article of the stack less than the linear distance between the paired holes.

Claim 8
Dependent Claim
29 words
A wicket according to claim 6 wherein the horizontally extending bearing member, the leg members and the shoulder members are connectedly and integrally formed from a unitary rod-like element.
Claim 9
Dependent Claim
32 words
A wicket according to claim 1 wherein the horizontally extending bearing member is adapted to bear on the topmost article of the stack only partly on a line between the paired holes.
Claim 10
Dependent Claim
29 words
A wicket according to claim 8 wherein the hoRizontally extending bearing member, the leg members and the shoulder members are connectedly and integrally formed from a unitary rod-like element.
Claim 11
Dependent Claim
