Interchangeable carton holder for chain conveyor

Claim 2

Carton holding and conveying facilities for carton filling and forming machines of the type in which an endless conveyor chain conveys spaced carton blanks past a filling station comprising an endless carton conveyor chain and support blocks at equally spaced intervals on said chain, each support block having a front face and a carton holding bracket detachably carried by each block with each bracket having a wall in flush engagement with the front face of each block, each bracket including a rear wall corresponding in size to the length of a carton to be carried, and portions extending at right angles to said rear wall in spaced relation, said portions having dimensions corresponding to the width dimensions of cartons to be accommodated, each bracket having flanges snugly embracing the sides of said block, each block and bracket having interfitting groove and projection means at the sides of said block and said flanges so as to enable a detachable connection between each bracket and block.

Claim 3

The structure of claim 1 wherein said groove and projection means includes projections extending from each side of each block and grooves carried by said flanges, said grooves being of multiangular configuration relative to the face of said blocks so as to enable said projections to be locked within said grooves.

Claim 4

The structure of claim 2 characterized by and including spring biased detent and recess means carried by said brackets and the front face of said blocks so as to resiliently lock said brackets to said blocks.

Claim 5

Chain supported block and carton holding bracket means for conveying carton blanks to a filling station for said cartons, including a plurality of chain supported blocks providing a plane of reference at an outer face of each block, and a plurality of interchangeable carton holding brackets of different sizes for use with said blocks, each carton holding bracket including a rear wall section of the same thickness and formed and adapted to be positioned in flush relation to the front face of said blocks, each bracket further including means for removably securing each bracket to each block, the rear wall of each bracket corresponding in length to the length of a carton blank, each carton bracket including spaced portions extending at right angles from said rear wall and having sizes corresponding to the width of carton blanks to be accommodated, the dimensions of said rear walls and right angular portions of each bracket being different from bracket to bracket while the thickness of said rear wall and extensions is essentially the same.

Claim 6

Chain supported block and carton holding bracket means for conveying carton blanks to a filling station for said cartons, including a plurality of chain supported blocks providing a plane of reference at an outer face of each block, and a plurality of interchangeable carton holding brackets of different sizes for use with said blocks, each carton holding bracket including a rear wall section of the same thickness and formed and adapted to be positioned in flush relation to the front face of said blocks, each bracket further including means for removably securing each bracket to each block, the rear wall of each bracket corresponding in length to the length of a carton blank, each carton bracket including spaced portions extending at right angles from said rear wall and having sizes corresponding to the width of carton blanks to be accommodated, the dimensions of said rear walls and right angular portions of each bracket being different from bracket to bracket while the thickness of said rear wall and extensions is essentially the same.
