Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
A skatewheel conveyor pallet comprising an open latticework grid defining an upper load bearing surface, an underside adapted for contact with the skatewheels of said conveyor, a pair of depending skirt members disposed along opposite side edges of said pallet and extending below the level of said upper surface, said skirt members adapted to extend beyond the sides of said conveyor and provide guide means for said pallet as it moves along said conveyor, a closed bearing surface extending adjacent each skirt member along the underside of said pallet and inboard of each said skirt member for engagement with skatewheels of said conveyor, braking means extending centrally along the underside of said pallet midway between said skirt members adapted to engage rubber wheels on said conveyor and thereby slow the speed of said pallet along said conveyor, openings in said grid extending through said pallet from said upper surface to said lower surface, drain means in said bearing surfaces, said braking means comprised of a gear-toothed rack.
Claim 2
Dependent Claim
167 words
A skatewheel conveyor pallet comprising an open latticework grid defining an upper load bearing surface, an underside adapted for contact with the skatewheels of said conveyor, a pair of depending skirt members disposed along opposite side edges of said pallet and extending below the level of said upper surface, said skirt members adapted to extend beyond the sides of said conveyor and provide guide means for said pallet as it moves along said conveyor, a closed bearing surface extending adjacent each skirt member along the underside of said pallet and inboard of each said skirt member for engagement with skatewheels of said conveyor, braking means extending centrally along the underside of said pallet midway between said skirt members adapted to engage rubber wheels on said conveyor and thereby slow the speed of said pallet along said conveyor, openings in said grid extending through said pallet from said upper surface to said lower surface, drain means in said bearing surfaces, said braking means comprised of a gear-toothed rack.
Claim 3
Dependent Claim
182 words
A skatewheel conveyor pallet comprising an open latticework grid defining an upper load bearing surface, an underside adapted for contact with the skatewheels of said conveyor, a pair of depending skirt members disposed along opposite side edges of said pallet and extending below the level of said upper surface, said skirt members adapted to extend beyond the sides of said conveyor and provide guide means for said pallet as it moves along said conveyor, a closed bearing surface extending adjacent each skirt member along the underside of said pallet and inboard of each said skirt member for engagement with skatewheels of said conveyor, braking means extending centrally along the underside of said pallet midway between said skirt members adapted to engage rubber wheels on said conveyor and thereby slow the speed of said pallet along said conveyor, openings in said grid extending through said pallet from said upper surface to said lower surface, drain means in said bearing surfaces, said braking means comprised of a gear-toothed rack, outwardly bevelled ends on said skirt members to provide feed guide means for said pallet.
Claim 4
Dependent Claim
182 words
A skatewheel conveyor pallet comprising an open latticework grid defining an upper load bearing surface, an underside adapted for contact with the skatewheels of said conveyor, a pair of depending skirt members disposed along opposite side edges of said pallet and extending below the level of said upper surface, said skirt members adapted to extend beyond the sides of said conveyor and provide guide means for said pallet as it moves along said conveyor, a closed bearing surface extending adjacent each skirt member along the underside of said pallet and inboard of each said skirt member for engagement with skatewheels of said conveyor, braking means extending centrally along the underside of said pallet midway between said skirt members adapted to engage rubber wheels on said conveyor and thereby slow the speed of said pallet along said conveyor, openings in said grid extending through said pallet from said upper surface to said lower surface, drain means in said bearing surfaces, said braking means comprised of a gear-toothed rack, outwardly bevelled ends on said skirt members to provide feed guide means for said pallet.
Claim 5
Dependent Claim
214 words
A skatewheel conveyor pallet comprising an open latticework grid defining an upper load bearing surface, an underside adapted for contact with the skatewheels of said conveyor, a pair of depending skirt members disposed along opposite side edges of said pallet and extending below the level of said upper surface, said skirt members adapted to extend beyond the sides of said conveyor and provide guide means for said pallet as it moves along said conveyor, a closed bearing surface extending adjacent each skirt member along the underside of said pallet and inboard of each said skirt member for engagement with skatewheels of said conveyor, braking means extending centrally along the underside of said pallet midway between said skirt members adapted to engage rubber wheels on said conveyor and thereby slow the speed of said pallet along said conveyor, openings in said grid extending through said pallet from said upper surface to said lower surface, drain means in said bearing surfaces, said braking means comprised of a gear-toothed rack, outwardly bevelled ends on said skirt members to provide feed guide means for said pallet and stop means disposed on said upper surface at opposite ends thereof for engaging the grid openings of another similar pallet in an inverted stacked position to prevent relative sliding motion thereof.
Claim 6
Dependent Claim
