Gripper devices for layers of brick mouldings

Claim 2

In a gripper device for locating layers of brick mouldings in stacks in inclined cross combination, each said layer consisting of an even number of parallel rows of bricks, outer jaws arranged to grip the outer longitudinal edges of the layers and, said outer jaws extending longitudinally of the rows and being fixed against longitudinal displacement relative to the rows, and first and second intermediate jaw means located between the outer jaws and arranged to engage between the longitudinal edges of the rows, said first and second intermediate jaw means extending longitudinally of the rows, the first intermediate jaw means being located between pairs of rows and being fixed against longitudinal displacement relative to the rows, and the second intermediate jaw means being displaceable longitudinally relative to the rows in a substantially rectilinear direction.

Claim 3

In a gripper device for locating layers of brick mouldings arranged in an even number of rows in stacks in inclined cross combination, outer jaws arranged to grip the rows, said outer jaws being fixed against displacement longitudinally relative to the rows, first and second intermediate jaw means located between the outer jaws and arranged to engage between the rows, the first intermediate jaw means being located between pairs of rows and being fixed against displacement longitudinally relative to the rows, and the second intermediate row means being displaceable longitudinally relative to the rows a frame, rail means connected to the frame, said rail means extending longitudinally of the rows, and roller means movable along the rail means, said roller means carrying the second intermediate jaw means.

Claim 4

In a gripper device for locating layers of brick mouldings arranged in an even number of rows in stacks in inclined cross combination, outer jaws arranged to grip the rows, said outer jaws being fixed against displacement longitudinally relative to the rows, first and second intermediate jaw means located between the outer jaws and arranged to engage between the rows, the first intermediate jaw means being located between pairs of rows and being fixed against displacement longitudinally relative to the rows, and the second intermediate row means being displaceable longitudinally relative to the rows a frame, rail means connected to the frame, said rail means extending longitudinally of the rows, and roller means movable along the rail means, said roller means carrying the second intermediate jaw means.

Claim 5

A gripper device as claimed in claim 2, further comprising resilient layers provided on opposite sides of the first and second intermediate jaw means.

Claim 6

In a gripper device for a layer of brick mouldings composed of a plurality of parallel rows of mouldings arranged side by side, outer jaws displaceable transversely of the rows to grip opposite longitudinal sides of the layer, the outer jaws being fixed against longitudinal displacement relative to the rows, at least one first intermediate jaw arranged between the outer jaws and extending longitudinally of the rows, and at least one pair of second intermediate jaws arranged between the outer jaws, the intermediate jaws being located between respective rows and extending longitudinally of the rows, and at least one pair of second intermediate jaws arranged between the outer jaws, the intermediate jaws being located between respective rows and extending longitudinally of the rows, the first intermediate jaw being located between the pair of second intermediate jaws and being fixed against longitudinal displacement relative to the rows, and the second intermediate jaws being mounted for longitudinal displacement relative to the rows in a direction parallel to the axis of the rows whereby the rows of mouldings are displaced into a herringbone configuration upon such longitudinal displacement of the second intermediate jaws.

Claim 7

In a gripper device for a layer of brick mouldings composed of a plurality of parallel rows of mouldings arranged side by side, outer jaws displaceable transversely of the rows to grip opposite longitudinal sides of the layer, the outer jaws being fixed against longitudinal displacement relative to the rows, at least one first intermediate jaw arranged between the outer jaws and extending longitudinally of the rows, and at least one pair of second intermediate jaws arranged between the outer jaws, the intermediate jaws being located between respective rows and extending longitudinally of the rows, and at least one pair of second intermediate jaws arranged between the outer jaws, the intermediate jaws being located between respective rows and extending longitudinally of the rows, the first intermediate jaw being located between the pair of second intermediate jaws and being fixed against longitudinal displacement relative to the rows, and the second intermediate jaws being mounted for longitudinal displacement relative to the rows in a direction parallel to the axis of the rows whereby the rows of mouldings are displaced into a herringbone configuration upon such longitudinal displacement of the second intermediate jaws.
