Abstract
Abstract The invention comprises a grain box cover device. The grain box cover device has a roller mounted along one side of the upper edge of a grain box. A sheet canvas is rolled onto the roller. A pair of rods are mounted below the upper edge of the box and have their one ends pivotally mounted to the other side of the box and extending toward the roller. The rods have their other ends terminating adjacent and beneath a lower portion of the roll of canvas. The canvas has flexible channels along its outer side edges which receive the outer end of the rods. Rope and pulling means are provided for pulling the front outer edge of the canvas across the top of the grain box in a direction toward the pivotal mounting of the rods, with the channel portions of the canvas sliding along the rods. The rods act to hold the outer side edges of the canvas below the upper edge of the box for effective closing of the box.

Claim 1
Independent Claim
254 words
A box cover device for covering the open top of a box of a truck and the like comprising a flexible sheet member having a length and width of at least slightly greater than the length and width of the open top of the box, a pair of elongated rods, said rods having a fixed length of at least near the length of the box and extending longitudinally along the length of the box on opposite sides of the box, said rods having enlarged heads at their forward ends of greater size than the lateral thickness of the rods, said rods having their rearward ends mounted to the rearward end of the box, said sheet members having reversely folded channels along their length to receive the enlarged heads and rods with the enlarged heads facilitating the telescoping action, cable means to draw the sheet member along the length of the box and along the length of the rods in a direction toward the rearward end of the box to draw the sheet member over the box to cover the box, a drum winding means mounted to the forward end of the box forward of the enlarged heads at the forward end of the rods, and rotatable in one direction to feed the sheet member onto the rods along the length of the box by the sheet member unwinding therefrom, said drum means being rotatable in the opposite direction to wind the sheet member back onto the drum for uncovering the top of the box.
