US Patent:

50742779, Dec 24, 1991

Filed:

May 20, 1991

Appl. No.:

7/702754

Inventors:

Harold J. Milholen - Siler City NC

Assignee:

Basic Machinery Company, Inc. - Siler City NC

International Classification:

B28D 106

US Classification:

125 1601

Abstract:

A cutter frame for cutting unfired brick material is provided with a tensioning leaf spring having a lateral mounting portion. A cutter wire end loop is positioned over the mounting projection and is placed in substantial tension by such spring. The mounting projection is deformed by plastic deformation to provide a fully curved cutter wire loop support surface. Since the support surface for the cutter wire is curved, sharp corners are eliminated and fatigue failures in the cutter wire are substantially reduced. Further, the smooth support surface allows the wire to automatically position itself to equalize the tension in each leg of the loop.

Abstract:

An automated system is provided for stacking brick in monorail jig box stacking systems. The apparatus includes a plurality of loader subassemblies which sequentially position layers of brick in a jig box supported by a monorail. Each loader assembly includes a supply conveyor operable to consolidate spaced groups of brick in one direction and a marshaling conveyor operable to consolidate groups of brick in a direction perpendicular to such one direction. The two conveyors operate to rearrange the brick so that groups or layers are produced which are sized to provide one full layer in the jig box. A transfer tray receives the layers from the marshaling conveyor and extends to carry such layers into the jig box. A stripper retains the layers in the jig box as the transfer tray is retracted. Camming surfaces carried by the transfer tray ensure that the jig box is properly positioned with respect to the tray before the layer of brick enters the jig box.
