Abstract

Abstract A toy bird having a housing, within the housing are two sheaves mounted to a common shaft for rotation together, one of the sheaves having a larger inside diameter that the other, a first wing and a second wing disposed outside the housing, each wing being provided with a tang that passes through an opening provided in the housing and which is mounted for rotation within the housing independently of the other tang, two resilient cords, each cord passing through a separate opening provided in the housing and attached to one of the sheaves, the cord passing through the opening on the upper section of the housing being attached to the sheave having the smaller inside diameter so that when each cord is pulled with approximately equal force the housing moves towards the end of the cord attached to the sheave having the smaller inside diameter, a shaft positioned off-center to the shaft attached to the two sheaves and passing through openings provided in the tang members causing its tang members to move when the sheaves are rotated, a cylinder and a piston mounted for reciprocal movement within the cylinder, the piston being operatively connected to the shaft that passes through the two openings, a sound producing mechanism is pneumatic connection with the bottom of the cylinder so that when the bird housing is caused to be moved upwardly and downwardly by force being applied or removed from one or both of the two cords, the wings "flutter" upwardly and downwardly and a sound is emitted each time the piston reciprocates in the cylinder.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 159 words
A toy bird, comprising: a housing, sheave means mounted for rotation within said housing and being provided with two separate posts of different dimension, a cord having two pieces, one of said pieces wound around one of said posts while the other of said pieces is wound around the other of said posts, said cord extending outwardly of said housing such that as said cord is pulled said sheave means rotates, wing means operably mounted for movement with respect to said housing and provided with slots, means operatively connecting said wing means and said sheave means, including a shaft offset from the axis of rotation of said sheave means and extending through said slots of said wing means such that as said sheave means rotates said wing means moves, noise producing means within said housing, and means operatively connecting said noise producing means and said sheave means such that as said sheave means rotates, said noise producing means operates.
Claim 2
Dependent Claim 159 words
A toy bird, comprising: a housing, sheave means mounted for rotation within said housing and being provided with two separate posts of different dimension, a cord having two pieces, one of said pieces wound around one of said posts while the other of said pieces is wound around the other of said posts, said cord extending outwardly of said housing such that as said cord is pulled said sheave means rotates, wing means operably mounted for movement with respect to said housing and provided with slots, means operatively connecting said wing means and said sheave means, including a shaft offset from the axis of rotation of said sheave means and extending through said slots of said wing means such that as said sheave means rotates said wing means moves, noise producing means within said housing, and means operatively connecting said noise producing means and said sheave means such that as said sheave means rotates, said noise producing means operates.
Claim 3
Dependent Claim 76 words
A toy bird as in claim 1, wherein said noise producing means is activated by the passage of air therethrough, and wherein said means operatively connecting said noise producing means and said sheave means comprises a shaft offset from the axis of rotation of said sheave means, a cylinder operatively connected to and in fluid connection with said noise producing means, and a piston mounted for reciprocating movement within said cylinder and connected to said shaft.
Claim 4
Dependent Claim 148 words
A toy bird as in claim 1, wherein said noise producing means comprises a cylinder disposed within said housing, said cylinder being hollow and having a closed first end and an open second end, a piston mounted for reciprocation within said cylinder and including a top wall and a cylindrical side wall depending therefrom, the outside diameter of said cylindrical side wall being substantially equal to the inside diameter of said cylinder maintaining a pneumatic seal therebetween, an element for producing an audible sound when air is forced therethrough being in pneumatic connection with the interior of said first cylinder at the closed end thereof, and means operatively connecting said piston at said top wall thereof to said means operatively connecting said sheave means and said wing means such that when said sheave means rotates said piston reciprocates within said cylinder causing said element to produce a sound.
Claim 5
Dependent Claim 188 words
In a toy having an element which produces a sound when air is moved therethrough and at least one member mounted for movement, the improvement comprising a sheave mounted for rotation about an axis and provided with first and second posts of different size and a first shaft extending outwardly therefrom at a position offset from said axis thereof, first and second cords attached to said first and second posts, respectively, a chamber within which said element is located, a plunger mounted for reciprocating movement within said chamber, said plunger being provided with a first elongated opening through which said first shaft of said sheave extends permitting the rotation of said sheave to move said plunger back and forth within said chamber forcing air through said element, a second stationary shaft, said member being provided with an opening therein through which said second shaft extends permitting said member to rotate about said second shaft, said member also being provided with a second elongated opening through which said first shaft of said sheave extends permitting the rotation of said sheave to rotate said one member about said second shaft.
Claim 6
Dependent Claim 188 words
In a toy having an element which produces a sound when air is moved therethrough and at least one member mounted for movement, the improvement comprising a sheave mounted for rotation about an axis and provided with first and second posts of different size and a first shaft extending outwardly therefrom at a position offset from said axis thereof, first and second cords attached to said first and second posts, respectively, a chamber within which said element is located, a plunger mounted for reciprocating movement within said chamber, said plunger being provided with a first elongated opening through which said first shaft of said sheave extends permitting the rotation of said sheave to move said plunger back and forth within said chamber forcing air through said element, a second stationary shaft, said member being provided with an opening therein through which said second shaft extends permitting said member to rotate about said second shaft, said member also being provided with a second elongated opening through which said first shaft of said sheave extends permitting the rotation of said sheave to rotate said one member about said second shaft.
Claim 7
Dependent Claim 78 words
A toy as in claim 4, further comprising a second member mounted for movement, a third stationary shaft, said second member being provided with an opening therein through which said third shaft extends permitting said second member to rotate about said third shaft, said second member also being provided with a third elongated opening through which said first shaft of said sheave extends permitting the rotation of said sheave to rotate said second member about said third shaft.
Claim 8
Dependent Claim 98 words
A toy as in claim 4, further comprising a housing within which said sheave is mounted for rotation, said housing being provided with an opening which is of a dimension at least twice the distance said first shaft is offset from the axis of rotation of said sheave such that said first shaft of said sheave extends through said opening and is free to rotate within said opening, said second and third shafts about which said members rotate extending outwardly from said housing, said housing also being provided with openings through which said first and second cords extend.
