Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
172 words
Drive means comprising a single-speed reversible motor with an output shaft, a drive pinion secured on said output shaft, first gear means including a first gear member and a second gear member axially spaced therefrom and a first overrunning clutch establishing drive between said first and second gear members in a single direction, second gear means including a third gear member and a fourth gear member axially spaced therefrom and a second overrunning clutch establishing drive between said third and fourth gear members in a single direction, said first and third gear members having a driving connection with said drive pinion, said second and fourth gear member having a driving connection with each other, said second gear member being driven from said drive pinion through said first gear member and said first overrunning clutch upon rotation of said motor in one direction, and said fourth gear member being driven from said drive pinion through said third gear member and said second overrunning clutch upon rotation of said motor in the other direction.
Claim 2
Dependent Claim
172 words
Drive means comprising a single-speed reversible motor with an output shaft, a drive pinion secured on said output shaft, first gear means including a first gear member and a second gear member axially spaced therefrom and a first overrunning clutch establishing drive between said first and second gear members in a single direction, second gear means including a third gear member and a fourth gear member axially spaced therefrom and a second overrunning clutch establishing drive between said third and fourth gear members in a single direction, said first and third gear members having a driving connection with said drive pinion, said second and fourth gear member having a driving connection with each other, said second gear member being driven from said drive pinion through said first gear member and said first overrunning clutch upon rotation of said motor in one direction, and said fourth gear member being driven from said drive pinion through said third gear member and said second overrunning clutch upon rotation of said motor in the other direction.
Claim 3
Dependent Claim
99 words
The drive means of claim 1 wherein said first and third gear members have meshing engagement with said drive pinion, said second and fourth gear members have meshing engagement with each other, said fourth gear member is driven in one direction from said drive pinion through said first and second gear members and said first overrunning clutch upon rotation of said motor in one direction, and said fourth gear member is driven in said one direction from said drive pinion through said third gear member and said second overrunning clutch upon rotation of said motor in the other direction.
Claim 4
Dependent Claim
51 words
The drive means of claim 2 wherein the diameters of said gear members are such that said fourth gear member is driven at one speed upon rotation of said motor in the said one direction and driven at a different speed upon rotation of said motor in the said other direction.
Claim 5
Dependent Claim
100 words
The drive means of claim 2 including first and second idler shafts on opposite sides of said output shaft parallel thereto; wherein said first and second gear members are rotatable concentrically of said first idler shaft and each have a hub portion, and said first overrunning clutch is interposed between said hub portions of said first and second gear members; and wherein said third and fourth gear members are rotatable concentricaLly of said second idler shaft and each have a hub portion, and said second overrunning clutch is interposed between said hub portions of said third and fourth gear members.
