Abstract
Abstract A noise-making clapper comprises a stack of a plurality of at least three elongated, flexible blades which are rigidly secured together at a first end. In one embodiment of the invention, each blade has a length different from the other blades and the blades are arranged in the stack in order of their successively increasing overall lengths and such that corresponding first ends of the blades are coterminous. In another embodiment of the invention, all the blades have the same length, but the blades are successively located in the stack such that at each end, the blades have a longitudinally overlapping arrangement. Hence, in both embodiments of the invention, the corresponding other ends of the blades have a successively increasing stepped relationship.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
110 words
A clapper for making noise comprising a stack of at least three elongated, flexible, juxtaposed rigid blades; and means located a longitudinal distance from a first end of said stack for securing said blades in said stack, said blades having successively increasing operative lengths from said securing means such that said stack has at the first end a successively increasing stepped relationship among said blades and each of said blades having a rigidity so as to enable each of said blades when arcuately bent to return to a straightened position upon the release of the bent blade thereby producing a noise by the returning blade striking a previously returned blade.
Claim 2
Dependent Claim
110 words
A clapper for making noise comprising a stack of at least three elongated, flexible, juxtaposed rigid blades; and means located a longitudinal distance from a first end of said stack for securing said blades in said stack, said blades having successively increasing operative lengths from said securing means such that said stack has at the first end a successively increasing stepped relationship among said blades and each of said blades having a rigidity so as to enable each of said blades when arcuately bent to return to a straightened position upon the release of the bent blade thereby producing a noise by the returning blade striking a previously returned blade.
Claim 3
Dependent Claim
55 words
A clapper as claimed in claim 1 wherein each blade in said stack has an overall length different from the other said blades, and the difference in the operative lengths between any set of two juxtaposed blades in said stack is substantially equal to the operative lengths between any other set of two juxtaposed blades.
Claim 4
Dependent Claim
40 words
A clapper as claimed in claim 2 wherein the other ends of said blades are coterminous and said securing means are located only at the other end of said stack, said stack consisting of blades having successively increasing overall lengths.
Claim 5
Dependent Claim
32 words
A clapper as claimed in claim 3 wherein each blade has planar top and bottom surfaces; and wherein said securing means fixedly secures said first ends of said blades in said stack.
Claim 6
Dependent Claim
18 words
A clapper as claimed in claim 1 wherein said securing means fixedly secures said blades in said stack.
Claim 7
Dependent Claim
17 words
A clapper as claimed in claim 1 wherein each said blade has planar top and bottom surfaces.
Claim 8
Dependent Claim
16 words
A clapper as claimed in claim 5 wherein each said blades are substantially rectangular in shape.
Claim 9
Dependent Claim
31 words
A clapper as claimed in claim 5 wherein each said blade comprises a substantially rectangular portion and an integral circular portion, said securing means being located only at said circular portion.
Claim 10
Dependent Claim
39 words
A clapper as claimed in claim 1 wherein each blade in said stack has substantially the same length and wherein said blades are successively located in the stack such that at each end the blades have a stepped relationship.
Claim 11
Dependent Claim
19 words
A clapper as claimed in claim 1 wherein each blade is comprised of a solid, synthetic, polymeric plastic material.
