Abstract
Abstract Energy is slowly stored in at least two spring members mounted juxtaposition one another, the stored energy being released substantially instantaneously and individually, a single member engaging a striker first, the striker then engaging an alarm device such as a bell, subsequent members striking prior members to move the striker and again engage the alarm device.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
101 words
A sound making system comprising a. a noise making device, b. a spring loaded striker intermittently striking said noise making device, c. at least two spring members, mounted juxtaposition one another, a distal end of said members intermittently engaging said spring loaded striker, and d. means selectively engaging said members for slowly bending said spring members to store energy therein substantially simultaneously and for releasing said energy substantially instantaneously and individually, a first spring member striking said spring loaded striker and the next succeeding spring member striking said first spring member so as to provide individual sounds in a predetermined sequence.
Claim 2
Dependent Claim
101 words
A sound making system comprising a. a noise making device, b. a spring loaded striker intermittently striking said noise making device, c. at least two spring members, mounted juxtaposition one another, a distal end of said members intermittently engaging said spring loaded striker, and d. means selectively engaging said members for slowly bending said spring members to store energy therein substantially simultaneously and for releasing said energy substantially instantaneously and individually, a first spring member striking said spring loaded striker and the next succeeding spring member striking said first spring member so as to provide individual sounds in a predetermined sequence.
Claim 3
Dependent Claim
14 words
A sound making system according to claim 1 wherein said spring members are blades.
Claim 4
Dependent Claim
15 words
A sound making system according to claim 2 wherein said blades are of different thicknesses.
Claim 5
Dependent Claim
14 words
A sound making system according to claim 2 wherein said distal ends are staggered.
Claim 6
Dependent Claim
30 words
A sound making system according to claim 4 wherein said spring blades are fixedly mounted and said means selectively engaging said blades comprises a rotating lug engaging said distal ends.
Claim 7
Dependent Claim
29 words
A sound making system according to claim 1 further comprising guide means cooperating with said means selectively engaging said blades to provide a smooth even bending of said blades.
Claim 8
Dependent Claim
33 words
A sound making system according to claim 6 wherein at least a portion of said sound making system is carried on a plate and said guide means include tangs extending from said plate.
Claim 9
Dependent Claim
56 words
A sound making system according to claim 1 wherein said spring loaded striker includes an axially movable rod engaging said sound making device, and a coil spring surrounding said rod and disposed between a tang extending from a plate carrying at least a portion of said noise making system and a collar carried by said rod.
Claim 10
Dependent Claim
25 words
A noise making system according to claim 1 further including stop means limiting the travel of said spring blades upon striking said spring loaded striker.
Claim 11
Dependent Claim
60 words
A noise making device according to claim 9 wherein said stop means includes a tang extending from a plate carrying at least a portion of said noise making system and disposed in cooperating relationship with said spring loaded striker such that the travel of said blades can be limited and yet permit said blades to strike said noise making device.
Claim 12
Dependent Claim
16 words
A noise making system according to claim 1 wherein said noise making device is a bell.
Claim 13
Dependent Claim
36 words
A noise making system according to claim 1 wherein said spring members are rotatably mounted and said means selectively engaging said spring members is a lug fixedly mounted in an interference path with said spring members.
