Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A quick acting, rotary power disconnect device for fuse-like removal of said rotary power from a driven shaft during shaft overload conditions, said device comprising two relative sliding members normally forced together under the urging of a spring means, first means on one of said members for imparting a rotary force to turn the other of said members, second means on the other of said members for receiving said force imparting means, and latch means for guiding said first and second means together during normal usage and for preventing said first and second means from coming together during said shaft overload conditions, wherein said first means comprises a first oF said sliding members having a plurality of pins extending radially therefrom and said second means comprising recesses in the other of said sliding members, said recesses being shaped to receive said pins under the force of said spring means.
Claim 2
Dependent Claim
149 words
A quick acting, rotary power disconnect device for fuse-like removal of said rotary power from a driven shaft during shaft overload conditions, said device comprising two relative sliding members normally forced together under the urging of a spring means, first means on one of said members for imparting a rotary force to turn the other of said members, second means on the other of said members for receiving said force imparting means, and latch means for guiding said first and second means together during normal usage and for preventing said first and second means from coming together during said shaft overload conditions, wherein said first means comprises a first oF said sliding members having a plurality of pins extending radially therefrom and said second means comprising recesses in the other of said sliding members, said recesses being shaped to receive said pins under the force of said spring means.
Claim 3
Dependent Claim
50 words
The device of claim 1 wherein said latch means comprises plurality of plates pivotally attached to said other member, said plates being near and individually associated with each of said recesses, said plates guiding said pins into said recess when said rotary power is first applied to said first member.
Claim 4
Dependent Claim
46 words
The device of claim 2 wherein an overload shaft condition causes said pins to slip out of said recesses and to move on to strike the plates to pivot them and to force them over said recesses for preventing said pin from again entering said recesses.
Claim 5
Dependent Claim
59 words
The device of claim 3 and a pair of concentric shafts with one of said shafts turning inside the other of said shafts, splines on the outer of said shafts, and means for sliding one of said members along said splines toward or away from the other of said members, said other member being keyed to the inner shaft.
Claim 6
Dependent Claim
21 words
The device of claim 3 and means for adjusting the force required for said pins to slip out of said recesses.
Claim 7
Dependent Claim
19 words
The device of claim 5 wherein said force adjusting means comprises means for adjusting the tension on said spring.
Claim 8
Dependent Claim
65 words
The device of claim 6 and a pair of concentric shafts with one of said shafts turning inside the other of said shafts, splines on the outer of said shafts, and means for sliding one of said members along said splines toward or away from the other of said members, said other member being keyed to the inner shaft under the urging of said spring.
