Filed:

Sep 25, 1992

Appl. No.:

7/951442

Inventors:

Charles G. Vaughn - Dobbs Ferry NY

Assignee:

Great American Management and Investment, Inc. - Chicago IL

International Classification:

B25J 1504

US Classification:

29225

Abstract:

An attachment device for attaching both compressible spring-type ceiling fixtures and noncompressible ceiling fixtures on an inverted T-shaped ceiling bracket. Opposed gripping surfaces on the outer ends of first and second pivotally attached arms are movable between first and second positions. The gripping surfaces include U-shaped recesses that can hold a noncompressible ceiling fixture for installing it on the ceiling bracket with the use of an elongated rod from a position on the floor. A recess is formed on the outer side of the bottom portion of each of the U-shaped gripping surfaces. An adapter having a base therein with projections on the inside of the adapter base can be mounted on the gripping surfaces with the projections engaging the recesses to retain the adapter on the outer end of the gripping tool. A noncompressible mounting ceiling fixture can be placed therein. Compressible spring-type ceiling fixtures can be placed in the recesses in the opposing gripping surfaces such that when the handles are moved toward each other, the spring fixture is compressed and its prongs opened.

Abstract:

A machine for forming a carton from a carton blank using a forming cavity uses at least one gripper for gripping and transporting the carton blank toward the forming cavity along a path of travel (such as from the hopper to a transporter in a linear fashion). A plurality of grippers may be provided for gripping and transporting the carton blank toward the forming cavity along the path of travel. The or each gripper may be adapted for gripping a lateral side of the carton blank, and the gripper(s) may be connected to a transporter adapted for moving in a reciprocal fashion along a linear path of travel. The machine may also include a forming cavity adapted for being raised and lowered, as well as a low level hopper for holding the carton blanks such that each is raised to associate with the gripper(s). Related methods are also disclosed.
