5/402878

Inventors:

Reynold Barkstrom - Hinsdale IL
Calvin P. Rickerd - La Grange Park IL
William C. Swanson - Clarendon Hills IL

Assignee:

International Harvester Company - Chicago IL

International Classification:

A01D 6900

US Classification:

56 108

Abstract:

A variable speed feed roll drive mechanism as provided for a forage harvester, the mechanism including a reversible hydrostatic transmission having its input shaft coupled with the chopper input shaft, the output of the transmission being coupled with the feed rolls. The hydrostatic transmission, having an infinitely variable range of output speeds provides the capability to infinitely vary the length of cut of crops passing through the chopper.

Appl. No.:

6/219404

Inventors:

William C. Swanson - Clarendon Hills IL

Assignee:

International Harvester Co. - Chicago IL

International Classification:

B60P 116

US Classification:

298 18

Abstract:

A receptacle lift apparatus for a cotton harvester or other dumping vehicle including a linear hydraulic motor including a first rod and piston assembly attached to the receptacle and a second rod and piston assembly attached to the chassis and a floating cylindrical housing receiving the first piston in one end and the second piston in the other end being independent of the chassis and receptacle for axially unrestrained movement relative thereto.

Appl. No.:

6/210985

Inventors:

William C. Swanson - Clarendon Hills IL
Evert J. Heersink - Hinsdale IL

Assignee:

International Harvester Co. - Chicago IL

International Classification:

A01B 63111

US Classification:

172 2

Abstract:

A multi-segment farm implement flexible tool bar or frame is provided with a hydraulic system including a rotary flow divider for raising and lowering each segment of the sectional frame in synchronous movement with the other sections. A mechanical linkage associated with a ground wheel positioning cylinder also activates the hydraulic fluid control system limiting the downward movement of the implement mounted to the sectional frame on its supporting gear.

Appl. No.:

6/156896

Inventors:

Leonard A. Bettin - Lyons IL
William C. Swanson - Clarendon Hills IL

Assignee:

International Harvester Co. - Chicago IL

International Classification:

A01B 6322

US Classification:

280 4323

Abstract:

An implement having a rotary flow divider controlling fluid to and from at least two independent hydraulic rams for raising and lowering the implement in a level manner. A counter totals the revolutions of the flow divider and actuates an electrical circuit which controls solenoid valves to stop the implement at the proper height.

Appl. No.:

6/156538

Inventors:

Randolph G. Fardal - Chicago IL
Edward L. Robinson - Naperville IL
William C. Swanson - Clarendon Hills IL

Assignee:

International Harvester Co. - Chicago IL

International Classification:

A01B 63108

US Classification:

172 2

Abstract:

The planter height and control system is adapted for use with an agricultural planter assembly which is adapted to be mechanically and hydraulically coupled to a tractor and which includes a frame, a plurality of equally spaced planter units mounted to the frame, and at least two wheel assemblies on each side of the planter assembly. Each wheel assembly is pivotally mounted to the frame and includes a piston and cylinder mechanism which, when the piston rod thereof is extended, pivots the wheel assembly downwardly to effect raising of the planter units. The system includes an electrical-hydraulic control circuit for parallel coupling the piston and cylinder mechanisms of the at least two wheel assemblies on each side of the planter assembly and for limiting the retraction of each piston rod of each piston and cylinder mechanism to a predetermined limit less than the full return stroke of the piston rod on the lowering of the planters thereby to control the height of the planter frame above the ground and thereby to provide limited relative movement of the piston rods of the piston and cylinder mechanisms for the at least two wheel assemblies on each side of the planter assembly as the planter assembly traverses uneven ground.

Filed:

Mar 3, 1981

Appl. No.:

6/240039

Inventors:

William C. Swanson - Clarendon Hills IL

Assignee:

International Harvester Co. - Chicago IL

International Classification:

F15B 102

US Classification:

60413

Abstract:

A hydraulically actuated clutch booster utilizes a seat accumulator incorporated in a vehicle seat suspension circuit for a source of fluid pressure when the normal clutch booster fluid supply pump is not operating thereby providing hydraulic assist to operate the vehicle's clutch upon initial start up.

Appl. No.:

7/149377

Inventors:

William C. Swanson - Clarendon Hills IL

International Classification:

B66F 900

US Classification:

414700

Abstract:

Level lifting and lowering of a working implement in combination with a hydraulic boom is provided through a hydraulic circuit and valve including a shuttle check valve, a rotary flow divider and a counterbalance valve. Selective operation results in the working implement being raised or lowered in a level displacement relative to the ground.
