Abstract
Abstract The toy is a ball or similar projectile which may be thrown and then retrieved by a hand-held line. The line winds on a reel, as in a yo-yo. The reel is connected to the ball by a torsion spring which winds up as the ball is thrown and then unwinds, reeling in the line and returning the ball to the hand. The toy requires less skill than a yo-yo.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
166 words
A toy, comprising: (a) a hollow rotatable hub member; (b) a reel mounted on the hub member; (c) a rigid housing containing said hub member and reel; (d) a fixed axle rigidly mounted in the housing and supporting the hub member for relative rotation with respect to the housing, said axle having a free end located within the hub member; (e) a torsion spring located within the housing and having two ends, one end being operatively attached to the housing and the other end attached to the hub member so that relative rotation between the hub member and the housing is resisted by tension in the spring; and (f) a flexible cord having a first end attached to the reel and a second free end passed through the housing, said cord being adapted for being coiled about the reel so that when the cord is moved, the reel and hub member rotate about the axle relative to the housing, resisted by the tension in the spring.
Claim 2
Dependent Claim
166 words
A toy, comprising: (a) a hollow rotatable hub member; (b) a reel mounted on the hub member; (c) a rigid housing containing said hub member and reel; (d) a fixed axle rigidly mounted in the housing and supporting the hub member for relative rotation with respect to the housing, said axle having a free end located within the hub member; (e) a torsion spring located within the housing and having two ends, one end being operatively attached to the housing and the other end attached to the hub member so that relative rotation between the hub member and the housing is resisted by tension in the spring; and (f) a flexible cord having a first end attached to the reel and a second free end passed through the housing, said cord being adapted for being coiled about the reel so that when the cord is moved, the reel and hub member rotate about the axle relative to the housing, resisted by the tension in the spring.
Claim 3
Dependent Claim
28 words
A toy as in claim 1 wherein the end of the spring that is operatively connected to the housing is connected to the free end of the axle.
Claim 4
Dependent Claim
39 words
A toy as in claim 1 wherein the hub member includes a bearing pin attached thereto, said bearing pin being coaxial with the axle and supported with respect to the housing by a bearing element attached to the housing.
Claim 5
Dependent Claim

Claim 6
Dependent Claim
26 words
A toy as in claim 1 wherein the housing includes an outer wall having the shape of a right circular cylinder with two planer end walls.
Claim 7
Dependent Claim
15 words
