Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
147 words
A pulley drive system comprising a drive pulley assembly, a driven pulley assembly, a belt coactively connecting said pulley assemblies, said driven pulley assembly being formed of first and second half-pulleys, said half-pulleys being relatively rotatable and relatively axially movable, said first half-pulley being adapted to drive associated apparatus, a belt-receiving portion structurally integral with said second half-pulley whereby rotary motion is imparted to said second half-pulley by said belt, said belt bearing upon said belt-receiving portion and being spaced from said first half-pulley when said second half-pulley is driven below a predetermined speed so that said belt does not contact said first half-pulley, and a centrifugal mechanism associated with said second half-pulley to impart axial movement to said second half-pulley upon said belt driving said second half-pulley at a predetermined speed to bring said belt into contact with said first half-pulley to drive said first halfpulley.
Claim 2
Dependent Claim
147 words
A pulley drive system comprising a drive pulley assembly, a driven pulley assembly, a belt coactively connecting said pulley assemblies, said driven pulley assembly being formed of first and second half-pulleys, said half-pulleys being relatively rotatable and relatively axially movable, said first half-pulley being adapted to drive associated apparatus, a belt-receiving portion structurally integral with said second half-pulley whereby rotary motion is imparted to said second half-pulley by said belt, said belt bearing upon said belt-receiving portion and being spaced from said first half-pulley when said second half-pulley is driven below a predetermined speed so that said belt does not contact said first half-pulley, and a centrifugal mechanism associated with said second half-pulley to impart axial movement to said second half-pulley upon said belt driving said second half-pulley at a predetermined speed to bring said belt into contact with said first half-pulley to drive said first halfpulley.
Claim 3
Dependent Claim
29 words
The pulley drive system of claim 1 wherein said belt is a V-belt and said belt-receiving portion is a generally cylindrical hub of sufficient length to receive said belt.
Claim 4
Dependent Claim
36 words
The pulley drive system of claim 2 wherein said first half-pulley includes a central recess sufficient to receive at least a portion of said hub when said second half-pulley is moved axially toward said first half-pulley.
Claim 5
Dependent Claim
29 words
The pulley drive system of claim 3 wherein interengageable means are carried in part by said second half-pulley for locking said driven pulley assembly portions against relative rotational movement.
Claim 6
Dependent Claim
45 words
The pulley drive system of claim 4 wherein said interengageable means includes hub external splines upon which said belt can ride and internal splines in said recess which coact with said hub external splines when a portion of said hub is received in said recess.
Claim 7
Dependent Claim
52 words
The pulley drive system of claim 2 wherein said driven pulley assembly is generally V-shaped whereby as said driven pulley assembly is driven above said predetermined speed and further axial movement is imparted to said second half-pulley a consequent outward radial movement is imparted to said belt on said driven pulley assembly.
Claim 8
Dependent Claim
41 words
The pulley drive system of claim 6 wherein said drive pulley assembly is formed of two half-pulleys and radial outward movement of said belt on said driven pulley assembly causes radial inward movement of said belt on said drive pulley assembly.
