In an overhead, underslung carrier-type material handling system: an overhead member having a plurality of side-by-side openings therethrough; a rail member having a plurality of side-by-side openings therethrough one beneath each of the openings through said overhead member; side-by-side rod-like members extending through said side-by-side openings in said overhead and rail members; devices on said rod-like members providing abutment surfaces surrounding the respective rod-like members facing in the direction of one another and at opposite sides of said overhead and rail members from one another; resilient, flexible, ring-like closed vessels connected by a conduit surrounding said rod-like members and between one of said overhead and rail members and the said abutment surfaces adjacent Thereto; and colored liquid within said chambers and said conduit means, said openings in said one of said overhead and rail members being larger than said rod-like members extending therethrough whereby said rod-like members have limited universal movement relative to said one of said overhead and rail members.

Claim 47

In an overhead, underslung carrier-type material handling system: an overhead member having a plurality of side-by-side openings therethrough; a rail member having a plurality of side-by-side openings therethrough one beneath each of the openings through said overhead member; side-by-side rod-like members extending through said side-by-side openings in said overhead and rail members; devices on said rod-like members providing abutment surfaces surrounding the respective rod-like members facing in the direction of one another and at opposite sides of said overhead and rail members from one another; discrete, resilient, flexible, ring-like closed vessels surrounding said rod-like members and between one of said overhead and rail members and each said abutment surfaces adjacent thereto; conduit means connecting said vessels between said overhead support and said abutment surfaces adjacent thereto; conduit means connecting said vessels between said rail member and said abutment surfaces adjacent thereto; and colored liquid within said chambers and said conduit means; said opening in said overhead and rail members being larger than said rod-like members extending therethrough whereby said rod-like members have limited relative universal movement relative to said overhead and rail members.

Claim 48

In an overhead, underslung carrier-type material handling system: an overhead member having a plurality of side-by-side openings therethrough; a rail member having a plurality of side-by-side openings therethrough one beneath each of the openings through said overhead member; side-by-side rod-like members extending through said side-by-side openings in said overhead and rail members; devices on said rod-like members providing abutment surfaces surrounding the respective rod-like members facing in the direction of one another and at opposite sides of said overhead and rail members from one another; discrete, resilient, flexible, ring-like closed vessels surrounding said rod-like members and between one of said overhead and rail members and each said abutment surfaces adjacent thereto; conduit means connecting said vessels between said overhead support and said abutment surfaces adjacent thereto; conduit means connecting said vessels between said rail member and said abutment surfaces adjacent thereto; and colored liquid within said chambers and said conduit means; said opening in said overhead and rail members being larger than said rod-like members extending therethrough whereby said rod-like members have limited relative universal movement relative to said overhead and rail members.
