Abstract
Abstract The conveyor includes a pouring line forming a part of a fixed conveyor. A plurality of cooling conveyor sections are movable laterally relative to and for selective longitudinal registry with the fixed conveyor. The discharge end of the fixed conveyor and the inlet ends of the movable conveyors each carry gates including frames mounting vertically reciprocable blades. When the fixed conveyor and a movable conveyor section in line with the fixed conveyor are filled with molds and castings, the blades of the gates register one with the other and are driven downwardly to shear through an empty mold. The mold filled cooling conveyor section is then moved laterally and another section brought into registry with the fixed conveyor and the cycle is repeated.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
147 words
A conveyor for a flaskless mold line having a series of molds engaged in face-to-face butting relation comprising first and second elongated conveyor sections disposed in end-to-end relation and forming a support for the molds of the mold line, means carried by at least one of said sections and adjacent the juncture of said first and second sections for separating the mold line and forming a pair of discrete mold lines on said first and second sections respectively, said separating means including a blade selectively movable into a first position engageable between a pair of adjacent molds at their interface and a second position spaced from the mold line, means for displacing the discrete mold line on one of said sections away from the other of said sections in a direction generally parallel to the direction in which said one section extends from the other mold section.
Claim 2
Dependent Claim
147 words
A conveyor for a flaskless mold line having a series of molds engaged in face-to-face butting relation comprising first and second elongated conveyor sections disposed in end-to-end relation and forming a support for the molds of the mold line, means carried by at least one of said sections and adjacent the juncture of said first and second sections for separating the mold line and forming a pair of discrete mold lines on said first and second sections respectively, said separating means including a blade selectively movable into a first position engageable between a pair of adjacent molds at their interface and a second position spaced from the mold line, means for displacing the discrete mold line on one of said sections away from the other of said sections in a direction generally parallel to the direction in which said one section extends from the other mold section.
Claim 3
Dependent Claim
44 words
A conveyor according to claim 1 wherein said separating means includes a frame carried by said one section and mounting said blade, and means mounting said frame for longitudinal movement relative to said one section for aligning said blade with a selected mold interface.
Claim 4
Dependent Claim
109 words
A conveyor according to claim 1 wherein said separating means includes a second blade selectively movable into a first position engageable between a pair of adjacent molds at their interface and a second position spaced from the mold line, said first mentioned blade and said second blade being carried by said first and second sections respectively and adjacent the juncture of said sections, said blades being engageable one with the other in back-to-back relation, said first and second blades in said first positions thereof serving to retain the respective molds on said first and second sections in face-to-face butting relation when said sections are separated one from the other.
Claim 5
Dependent Claim
66 words
A conveyor according to claim 3 wherein said separating means includes first and second frames adjacent the juncture of said first and second sections respectively, means carried by said first and second frames for respectively mounting said first and second blades for vertical movement between said first and second positions thereof, and means for moving said first and second blades between said first and second positions.
Claim 6
Dependent Claim
96 words
A conveyor according to claim 1 wherein said second conveyor section is adapted to receive molds from said first section, said second section including means for carrying the molds thereon for translatory movement in a longitudinal direction away from said first section and without sliding movement of such molds relative to said second section, and means for moving said second section in an opposite longitudinal direction with a force sufficient to overcome the frictional forces between the molds on said second section and said second section whereby the molds are not moved in said second direction.
Claim 7
Dependent Claim
154 words
A conveyor according to claim 1 including a third conveyor section, means mounting said second and third conveyor sections for movement into and out of longitudinal registry with said first conveyor section, said first mentioned blade being carried by said first section, second and third blades carried by said second and third sections respectively, each of said second and third blades being selectively movable into a first position engageable between a pair of adjacent molds at their interface and a second position spaced from the mold line when the respective one of said second and third section lies in registry with said first section, said first and second blades being engageable one with the other in back-to-back relation when said first and second sections register one with the other, said first and third blades being engageable one with the other in back-to-back relation when said first and third sections register one with the other.
