Abstract
Abstract A drive mechanism for corn header gathering unit which is housed in a gear box designed so as to serve as an integral mounting member between the gathering unit and the main frame of a combine on which the unit is adapted to be mounted. The mechanism incorporates a single power input-output shaft assembly for a multi-row gathering unit which includes bevel gear drives for stalk rolls and gathering chains and a safety clutch, with all the gear components submerged in a lubricant and the safety clutch in a separate lubricant containing compartment and with a readily removable cover plate on the gear box which provides easy access for servicing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
151 words
A power driving mechanism for corn gathering units which are adapted to be mounted on a cross member on the forward end of a harvesting combine which mechanism comprises an elongate gear box having corn harvesting rolls and associated gathering chains mounted thereon and extending in a fore and aft direction from the front wall thereof, a power input output shaft assembly mounted in said gear box and including an input power shaft extending through opposite ends of said elongate gear box, a gear train connecting said power input-output shaft assembly in driving relation with each harvesting roll, a gear train connecting said power input-output shaft assembly in driving relation with each said gathering chain and an overload safety clutch interposed between said power input-output shaft assembly and said gear trains, each of said gear trains including a drive gear coaxially mounted in spaced relation on said power inputoutput shaft assembly.
Claim 2
Dependent Claim
151 words
A power driving mechanism for corn gathering units which are adapted to be mounted on a cross member on the forward end of a harvesting combine which mechanism comprises an elongate gear box having corn harvesting rolls and associated gathering chains mounted thereon and extending in a fore and aft direction from the front wall thereof, a power input output shaft assembly mounted in said gear box and including an input power shaft extending through opposite ends of said elongate gear box, a gear train connecting said power input-output shaft assembly in driving relation with each harvesting roll, a gear train connecting said power input-output shaft assembly in driving relation with each said gathering chain and an overload safety clutch interposed between said power input-output shaft assembly and said gear trains, each of said gear trains including a drive gear coaxially mounted in spaced relation on said power inputoutput shaft assembly.
Claim 3
Dependent Claim
26 words
A power driving mechanism as set forth in claim 1 wherein said elongate gear box and contents is adjustable along the axis of said drive shaft.
Claim 4
Dependent Claim
38 words
A power driving mechanism as set forth in claim 1 wherein said gear box has a readily removable cover member providing access to said gear trains and means enabling said gear trains to be immersed in a lubricant.
Claim 5
Dependent Claim
57 words
A power drive mechanism as set forth in claim 1 wherein said input-output shaft assembly comprises a sectionalized tubular output shaft assembly into which said input power shaft coaxially extends with the sections thereof driven by a safety clutch forming an integral part of a common gear train for driving a pair of the corn harvesting rolls.
Claim 6
Dependent Claim
25 words
A power drive mechanism as set forth in claim 4 wherein each said output shaft section has a separate driving connection with said safety clutch.
Claim 7
Dependent Claim

Claim 8
Dependent Claim
134 words
A power driving mechanism for multi-row corn gathering units which are adapted to be shiftably mounted on the forward end of a harvesting combine which mechanism comprises an elongate gear box having means for mounting on a forward portion of the frame of said combine, corn harvesting rolls mounted on said gear Box and extending forwardly thereof in cantilever fashion, a power shaft assembly including an input shaft and an output shaft assembly coaxially mounted in said gear box with said input shaft extending through opposite ends thereof, a gear train connecting the output shaft assembly with each harvesting roll, and an overload safety clutch incorporated in said power shaft assembly and forming a drive connection between said input shaft and said output shaft assembly, said gear train including a gear surrounding said clutch.
Claim 9
Dependent Claim
134 words
A power driving mechanism for multi-row corn gathering units which are adapted to be shiftably mounted on the forward end of a harvesting combine which mechanism comprises an elongate gear box having means for mounting on a forward portion of the frame of said combine, corn harvesting rolls mounted on said gear Box and extending forwardly thereof in cantilever fashion, a power shaft assembly including an input shaft and an output shaft assembly coaxially mounted in said gear box with said input shaft extending through opposite ends thereof, a gear train connecting the output shaft assembly with each harvesting roll, and an overload safety clutch incorporated in said power shaft assembly and forming a drive connection between said input shaft and said output shaft assembly, said gear train including a gear surrounding said clutch.
Claim 10
Dependent Claim
23 words
A power driving mechanism as set forth in claim 7 wherein said elongate gear box and contents are shiftable along said input shaft.
Claim 11
Dependent Claim
28 words
A power driving mechanism as set forth in claim 7 wherein the input shaft of said power shaft assembly and the output shaft assembly are in telescoping relation.
Claim 12
Dependent Claim
29 words

Claim 13
Dependent Claim
61 words
A power driving mechanism as set forth in claim 7 wherein said power shaft assembly comprises a single input shaft and an output shaft assembly telescoped thereon with a drive gear having a driving connection with a pair of corn harvesting rolls and separate drive gears having driving connection with gathering chains which are associated with the respective corn harvesting rolls.
Claim 14
Dependent Claim
86 words
A power driving mechanism as set forth in claim 7 wherein said gear box has a removable top cover member and wherein said input shaft extends in telescoped relation within said output shaft assembly and said power shaft assembly is mounted in said gear box so that the assembly may be immersed in a lubricant in the gear box while the input shaft and associated safety clutch may be immersed in a lubricant within the output shaft assembly independently of the lubricant in the gear box.
