Abstract
Abstract A conveyor cleat releasably attachable to a rod conveyor has a cleat blade for retaining goods during conveyance, a cleat base attached to the cleat blade base, and a pair of flexible lips for releasably retaining adjacent conveyor rods. The lips are integral with the cleat base and define rod-receiving channels which have channel openings facing in a direction opposite to the direction of travel of the conveyor cleat. The lips also provide the corresponding channels with closed channel bottoms located ahead of the corresponding conveyor rod as seen in the direction of travel of the cleat. The cleats according to the subject invention are easily and economically manufactured, preferably by extrusion, are readily attached to rod conveyors without the use of any special tools or clamping devices, securely maintain themselves in position during travel, and are nevertheless easily removed after use without disassembly or prolonged downtime of the conveyor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
254 words
A conveyor cleat releasably attachable to a rod conveyor having a plurality of rods for conveying goods, comprising in combination: a cleat blade for retaining goods during conveyance, the cleat blade having a front surface facing in a direction of travel of the conveyor when the cleat is attached to the conveyor; a cleat base attached to the cleat blade for supporting the cleat blade; a first flexible lip integral with the cleat base for releasably retaining a first conveyor rod, the first lip and the cleat base defining a first channel for receiving the first conveyor rod, the first channel being located below the cleat blade and behind said front surface as seen in said direction of travel, the first lip and the cleat base further defining for the first channel a channel opening facing substantially in a direction opposite to said direction of travel, and the first lip providing the first channel with a closed channel bottom located ahead of said first conveyor or rod as seen in said direction of travel when the cleat is attached to the conveyor; and a second lip integral with the cleat base and defining with the cleat base a second channel for receiving a second conveyor rod located adjacent the first conveyor rod, the second channel being located behind the first channel as seen in said direction of travel, and the second lip and the cleat base defining for the second channel a channel opening facing in a direction opposite to said direction of travel.
