Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
73 words
A centrifugal clutch comprising a sleeve, means to secure the sleeve to a spindle, a plurality of weights, an integral resilient body surrounding said weights circumferentially and extending over the opposite ends thereof to axially position said weights, said body being sufficiently radially resilient to be expanded radially by the centrifugal force of the weights thereon as said body is rotated and rigid means to limit the outward radial movement of said weights.
Claim 2
Dependent Claim
73 words
A centrifugal clutch comprising a sleeve, means to secure the sleeve to a spindle, a plurality of weights, an integral resilient body surrounding said weights circumferentially and extending over the opposite ends thereof to axially position said weights, said body being sufficiently radially resilient to be expanded radially by the centrifugal force of the weights thereon as said body is rotated and rigid means to limit the outward radial movement of said weights.
Claim 3
Dependent Claim
13 words
A centrifugal clutch as in claim 1 wherein said weights are symmetrically arranged.
Claim 4
Dependent Claim
16 words
A centrifugal clutch as in claim 1 wherein the means is a ring on each weight.
Claim 5
Dependent Claim
25 words
A centrifugal clutch as in claim 1 wherein the means is a ring on each weight with recesses on the cooperating weights to receive it.
Claim 6
Dependent Claim
22 words
A centrifugal clutch as in claim 3 wherein the means is a ring in said body and located circularly about said weights.
Claim 7
Dependent Claim
29 words
A centrifugal clutch as in claim 3 wherein said weights are recessed and a portion of a ring on one weight is lOcated in the recess of another weight.
