Abstract
Abstract A secondary case magazine is provided above and to one side of an upwardly open primary case magazine from which the lowermost case is cyclically withdrawn for erection. The secondary magazine is disposed generally horizontally, and holds a large number of cases in generally vertical edgewise relation. Escapement means at the exit end of the secondary magazine successively ejects each case for downward movement onto the stack of cases in the primary magazine. Means in the secondary magazine urges all of the cases therein toward said exit end, and said means operates in timed relationship with said escapement means and said means for withdrawing the lowermost case from the primary magazine.

Claim 3
Dependent Claim
126 words
The combination defined in claim 1 wherein said pallet includes a lower shear plate for engaging a lower side edge of said downstream case during upward vertical movement thereof to raise the same above said first fixed stop, said pallet further including an upper shear plate engageable with the upper side edge of said downstream case during downward vertical movement of said pallet, and an upper fixed stop aligned with said first fixed stop for normally retaining said cases in compacted relationship in said secondary magazine, said upper shear plate serving to move the upper side edge of said downstream case downwardly past said upper fixed stop so that the line pressure of the succeeding cases in said secondary magazine forces said furthest downstream case outwardly.
Claim 4
Dependent Claim
58 words
The combination defined in claim 2 wherein said escapement means further includes guide means associated with said lower fixed stop and movable into and out of the open end of said horizontal magazine for deflecting said downwardly moving lower side edge of said case outwardly with respect to said lower fixed stop during downward movement of said pallet.
Claim 5
Dependent Claim
59 words
The combination defined in claim 3 wherein said case guide means further includes a fixed shelf against which the lower side edge of said case is adapted to drop after being guided past said lower fixed stop whereby said case pivots about its lower side edge and enters said upwardly open magazine in a flat folded substantially horizontal position.
Claim 6
Dependent Claim
82 words
The combination defined in claim 1 wherein said means for urging all of said edgewise cases toward one end of said secondary magazine comprises an endless belt conveyor having an upper run for engaging the lower side edges of said folded cases in said secondary magazine, drive means for said belt conveyor, said drive means being intermittently operable in timed relationship with reciprocable movement of said pallet to advance all of said folded cases toward said one end of said secondary magazine.
Claim 7
Dependent Claim
76 words
The combination defined in claim 1 wherein said means for urging all of said cases toward said one end of said secondary magazine comprises a case engaging pusher slidably supported in said secondary magazine for movement toward and away from said open end thereof, and biasing means for urging said pusher toward said one end with a force which is relatively constant with reference to the particular position of said pusher along its path of movement.
Claim 8
Dependent Claim
99 words
The combination defined in claim 5 wherein said means for urging all of edgewise cases toward said one end of said secondary magazine further includes a depending case engaging pusher slidably supported in an upper wall of said secondary magazine for movement toward and away from said open end thereof, and biasing means for urging said pusher into contact with the rearmost case in said secondary magazine for advancing all of said folded cases toward said open end with a force which is relatively constant with reference to the particular position of said rearmost case in said secondary magazine.
Claim 9
Dependent Claim
123 words
The combination defined in claim 7 wherein said pallet includes a lower shear plate for engaging a lower side edge of said downstream case during upward vertical movement thereof to raise said case above said first fixed stop, said pallet further including an upper shear plate engageable with the upper side edge of said downstream case during downward vertical movement of said pallet, and an upper fixed stop aligned with said first fixed stop for normally retaining said cases in compacted relationship against the bias of said pusher and belt, said upper shear plate serving to move the upper side edge of said downstream case downwardly past said upper fixed stop so that said case is urged outwardly by said pusher and belt.
Claim 10
Dependent Claim
133 words
In a machine for erecting packing cases, and including an upwardly open magazine for storing a predetermined number of flat folded cases in a stack, the improvement comprising a secondary case magazine located above and to one side of said upwardly open magazine for storing folded cases edgewise on a lower wall thereof, means for urging all of said edgewise blanks toward an exit end of said secondary magazine, stop means at said exit end, means for cyclically withdrawing the lowermost case in said stack for erection, escapement means at the exit end of said secondary magazine for cyclically moving the endmost edgewise blank in its own plane so that the line pressure of the cases in said secondary magazine cyclically releases said endmost case to drop downwardly into said upwardly open magazine.
