Abstract
A feeder assembly for a combine including a conveyor having a plurality of laterally spaced driving chains entrained about and supported by a pair of for-and-aft spaced lateral supports. An elastomeric assembly is removably fitted about and is adapted for rotation with one of the supports to define a replaceable wear surface for the support while attenuating noise generated by the feeder assembly during operation thereof.
Claims17
A feeder assembly for a combine, said feeder assembly for a combine. said feeder assembly comprising:
- at least two laterally spaced endless metal chains having laterally elongated material engaging slats driven thereby;
- first and second laterally elongated chain supports arranged in fore-and-aft spaced relation relative to each other and about which the metal chains orbitally move in unison relative to each other, said first support having laterally spaced sprockets arranged in driving relation relative to said metal chains and with the second support defining a relatively smooth metal outer surface between opposite ends thereof;
- and
- an annularly formed elastomeric assembly non-rotatably fitted between the smooth outer metal surface of the second support and each of said metal chains to dampen contact noise between the melt chains and the support thereby reducing noise generation as the chains move thereabout.

A feeder assembly for a combine, said feeder assembly comprising:
- a fore-and-aft elongated conveyor including at least two tensioned and laterally spaced endless driving metal chains having a plurality of feeder slats spanning the lateral distance between and connected to the driving chains;
- front and rear metal supports for supporting each of said driving chains for movement thereabout, said rear metal Support including laterally spaced sprockets arranged in driving engagement with said metal chains and with said front support having a relatively smooth metal outer surface between opposite ends thereof;
- an elastomeric assembly which slides circumferentially over and along to frictionally engage the outer metal surface of said front support, said elastomeric assembly having an outer surface which resiliently engages an underside of the chains as they pass about the front support.
A feeder assembly for a combine, said feeder assembly comprising:
- first and second metal drive chains having corresponding sections extending generally parallel to each other, each chain section defining at least a first surface and a second surface Spaced from said first surface;
- a plurality of laterally elongated feeder slats connected to and driven by said chains, each feeder slat extending beyond the first surface of the chain sections;
- a housing which envelopes said drive chains and feeder slats:
- first and second metal supports connected to said housing for supporting said chains for movement thereabout, said first support including sprockets for imparting endwise movements to said metal chains and said second support defining a relatively smooth outer cylindrical metal surface along the length thereof;
- and
- a plurality of annularly formed elastomeric members fitted between the outer cylindrical metal surface of said second support and the second surface of the chain sections that move about the second support thereby dampening contact noise between the metal chains and the second support.

A feeder assembly for a combine, said feeder assembly comprising:
- a conveyor including a plurality of side-by-side metal driving chains movable in unison relative to each other;
- a housing which envelopes said conveyor;
- first and second fore-and-aft spaced laterally elongated metal supports connected to said housing for supporting said metal chains for movement thereabout, said first support including laterally spaced sprockets for driving said metal chains in unison relative to each other and said second support defining a relatively smooth outer cylindrical surface;
- and
- an annularly shaped elastomeric member disposed between each metal chain and said second support each elastomeric member having a smooth cylindrical inner surface sized to establish a frictional fit with the outer cylindrical surface of said second support to inhibit relative rotational movement therebetween and an outer surface provided with a profiled configuration for engaging said
- metal chains and thereby reducing the noise generated by the metal chains moving about the second support.
