Conveyor section of multi-section conveyor
First Claim
1. For use in a multi-section belt conveyor, the conveyor section comprising:
- a continuous conveyor belt;
a slider bed defining a longitudinally extending support plate and longitudinally extending, channel-shaped, opposite side edge members, wherein said support plate carries said conveyor belt for longitudinal movement along an upper surface thereof, and at least a first of said side edge members defines a first longitudinally extending slot therethrough near a proximal end of the slider bed;
a pair of transversely spaced, longitudinally disposed extension arms each having a proximal end portion and a distal, channel-shaped shank portion, each shank portion slidably engaging an opposite side edge member of the slider bed at a proximal end thereof, wherein at least said shank portion engaging the first side edge member defines a second slot therethrough, the proximal end of the second slot overlapping the distal end of the first slot, defining an overlapping portion of the first and second slots;
a proximal belt roller carried on a transverse roller shaft by the proximal end portions of the extension arms and engaging said continuous conveyor belt;
a belt tensioner carried in said overlapping portion of the first and second slots, having opposed first and second pushing blocks threadedly connected by a rod having oppositely threaded ends such that upon rotation in a first direction the pushing blocks are moved relatively apart and upon rotation in the opposite direction the pushing blocks are moved relatively together;
wherein each pushing block defines a longitudinal groove in its outer edge and receives in said groove the edges of the first and second slots, retaining together the first side edge member of the slider bed and its extension arm; and
wherein said rod is of sufficient length that, upon rotation in the first direction, it applies tension to the conveyor belt by causing the pushing blocks to extend the extension arm with respect to the slider bed by separating the proximal end of the second slot from the distal end of the first slot.

Abstract
In a multi-section conveyor, a conveyor section provides a belt tension adjusting mechanism employing extension arms on an expanding tensioner. The extension arms carry the end belt roller and apply increased tension to the belt as the arms extend. The opposed end rollers of adjacent sections are joined to coaxial end gears, and an intermediate idler gear interconnects the end gears when the sections are joined. When sections are assembled, the extension arms mate into the neighboring section and are contoured to permit angular variation in the mating. A latching mechanism on one section locks the end roller of the next section in engagement slots and boxes the gears for safety.

10. In a multi-section belt conveyor, the conveyor section comprising:
-
a continuous conveyor belt; a slider bed defining a longitudinally extending support plate and longitudinally extending, channel-shaped, opposite side edge members, wherein said support plate carries said conveyor belt for longitudinal movement along an upper surface thereof; a pair of transversely spaced, longitudinally disposed extension arms each having a proximal end portion and a distal, channel-shaped shank portion;
wherein;each said shank potion of the extension arms slidably engages an opposite side edge member of the slider bed at a proximal end thereof; the distal end of the slider bed comprises channel-shaped opposite side edge members having a channel height sufficient to receive the shank potion of an extension arm longitudinally therein; each said proximal end portion of the extension arms comprises a roller carrying means; the upper edge of the proximal end portion defines a notch between said roller carrying means and said shank portion; and the lower edge of the proximal end portion is recessed with respect to the vertical thickness of the shank portion, such that the proximal end portion has vertical pivotal freedom when engaged, in use, in the side edge members of the distal end of a like conveyor section; a proximal belt roller carried on a transverse roller shaft, engaged by said roller carrying means and engaging said continuous conveyor belt; and a means for applying tension to the conveyor belt by extending extension arms with respect to the slider bed. - View Dependent Claims (11)
