Abstract
Abstract Two similar, closely adjacent turntables independently mounted in the travel plane of a main roller conveyor. Each turntable being provided with a plurality of parallel, power driven table rollers lying in the plane of the rollers of the main roller conveyor. The turntables being independently rotatable so that the table rollers can be directed in any desired direction so as to direct loads from the main conveyor onto intersecting side roller conveyors or from the side conveyors onto the main conveyor in either direction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
127 words
A load transfer device for directing travelling loads between a main roller conveyor to an intersecting lateral conveyor comprising: a. two turntable structures positioned in side-by-side relation in axial alignment with the load path of said main conveyor and upon opposite sides of the projected axis of the lateral conveyor; b. an independent annular, horizontally rotatable load-roller frame mounted on each turntable structure; c. parallel, spaced, rotatable load-supporting rollers mounted in each load-roller frame in the plane of the rollers of said main conveyor; and d. means for independently and horizontally rotating each of said load-roller frames so as to position the axes of the loadsupporting rollers thereof at various angles to the axes of the main conveyor rollers to direct the travelling loads in desired directions.
Claim 2
Dependent Claim
127 words
A load transfer device for directing travelling loads between a main roller conveyor to an intersecting lateral conveyor comprising: a. two turntable structures positioned in side-by-side relation in axial alignment with the load path of said main conveyor and upon opposite sides of the projected axis of the lateral conveyor; b. an independent annular, horizontally rotatable load-roller frame mounted on each turntable structure; c. parallel, spaced, rotatable load-supporting rollers mounted in each load-roller frame in the plane of the rollers of said main conveyor; and d. means for independently and horizontally rotating each of said load-roller frames so as to position the axes of the loadsupporting rollers thereof at various angles to the axes of the main conveyor rollers to direct the travelling loads in desired directions.
Claim 3
Dependent Claim
37 words
A load transfer device as described in claim 1 having power means on each turntable structure for rotating the load-supporting rollers of that structure in either direction independently of the load-supporting rollers of the other turntable structure.
Claim 4
Dependent Claim
37 words
A load transfer device as described in claim 2 having stop means on each turntable structure acting to limit the degree of horizontal rotation of the load-roller frame of the respective section independently of the other section.
