Patent number: 4376592Abstract: This relates to the mounting of a control shaft for a machine. The control shaft is formed in sections and each shaft section other than a starting section is supported by a single bearing. Adjacent ends of the shaft sections are formed with projecting half-circular cross-sectional portions which are overlapped and then are clamped together by a radially expanding wedge device disposed within a sleeve encircling the shaft portions.Type: GrantFiled: May 8, 1980Date of Patent: March 15, 1983Assignee: Teepak, Inc.Inventor: Harold H. Martinek

Patent number: 4376554Abstract: An improved implement wheel includes two wheel halves permanently secured together, such as by welding. The first wheel half includes a bearing seat and the second wheel half includes a threaded nipple for receiving a bearing engagement member, such as a screw cap. A bearing is seated in the bearing seat defined in the first wheel half and is secured therein by the screw cap. The wheel bearing can be replaced easily by removing the screw cap, without necessitating wheel disassembly.Type: GrantFiled: January 26, 1981Date of Patent: March 15, 1983Assignee: International Harvester Co.Inventor: William G. Schumacher

Patent number: 4118951Abstract: A drive unit for selectively effecting driving or free-wheeling condition of propeller shafting in a motor vehicle comprising a drive unit for attachment to and/or attached to spaced-apart portions of an automobile propeller shaft for selectively establishing drive relationship or free-wheeling relationship between the propeller shaft portions as desired including:(a) an elongate first member for extending for at least the full distance between adjacent ends of portions of a propeller shaft;(b) a second member with first bearing members in supporting relationship between the second member and one part of the first member;(c) a third member with additional bearing members in supporting relationship between the third member and a second part of the first member;(d) first coupling structure for selectively locking or unlocking the first member along with the second member to or from one portion of a propeller shaft;(e) second coupling structure for selectively locking or unlocking the first member along with theType: GrantFiled: July 28, 1977Date of Patent: October 10, 1978Inventor: Leo B. Neasham

Patent number: 4068907Abstract: The combination with a housing or casing having an opening for projection outwardly therethrough of a shaft, the opening being of greater diameter than the shaft and rigidly receiving a mounting projecting beyond the casing and having a bore for journalling of the shaft, an inner bearing race fixedly engaged upon the mounting exteriorly of the casing for accommodating a plurality of discrete bearings, an outer race engaged to the shaft for rotation therewith, and a pulley or wheel member fixed on the outer race radially outwardly of the fixed inner race and mounting member.Type: GrantFiled: December 23, 1976Date of Patent: January 17, 1978Inventor: Edwin A. Zenthoefer

Patent number: 4040338Abstract: A fluid supply distributor communicates fluid from a stationary fluid source to a rotating hydraulic motor. The distributor includes a housing with main ports for connection to high and low pressure at the source. A shaft rotating in the housing is attached to the motor and includes motor ports for connection to the rotating motor. A sleeve in the housing surrounds the shaft, and the sleeve and shaft define interfacing sealing surfaces. The housing, the sleeve, and the shaft include passages for communicating fluid between the main ports and the motor ports. The sleeve is normally retained in a stationary position, but is released to rotate within the housing should the shaft seize within the housing. The passages include spaced supply grooves at the sealing surfaces connected to the main ports and thus maintained at different pressures.Type: GrantFiled: June 14, 1976Date of Patent: August 9, 1977Assignee: Logansport Machine Co., Inc.Inventors: John J. Wilson, Donald M. Rhoades

Patent number: 3998560Abstract: This invention pertains to an automatically-closing coupling which is adaptable to permit either roundended or square-ended shafts to be laterally inserted thereinto. Pedestals, including anti-function bearing rotatably support driving and driven spindles. Lateral slots are provided in the pedestals, in intermediate locking sleeves and in the spindles into which the ends of a shaft are freely received when the slots are all rotated into alignment and held by a detent means. After the shaft is inserted, a quarter turn of the spindle causes relative rotation between the spindles and the sleeves, locks the shaft in the spindles and releases the detent means, thus allowing free rotation of the shaft and spindles relative to the pedestals.Type: GrantFiled: April 27, 1976Date of Patent: December 21, 1976Inventor: Lawrence R. Damour
-
Patent number: 3994543Abstract: A locking device having a partial bearing surface formed by a shaft cradle. A restraining enclosure is formed by the shaft cradle and a slidably reciprocating detent having a recess therein, the detent being urged to form said restraining enclosure by a tension means.Type: GrantFiled: February 28, 1975Date of Patent: November 30, 1976Assignee: Lamcor IncorporatedInventor: Simeon A. Melugin
-
Patent number: 3990802Abstract: An electric motor having a removable shaft assembly comprising a plate member attached to the motor core, an assembly shaft, and a bearing arrangement attached at one end to the assembly shaft and at the other end to the plate member.Type: GrantFiled: March 17, 1975Date of Patent: November 9, 1976Inventor: Thomas Corona
-
Patent number: 3970398Abstract: This invention relates to a coupling for joining axially aligned shafts that are splined by utilizing an idle shaft supported to a bearing which shaft in turn supports each of the axially aligned shafts independently of each other whereby either of said mating shafts may be removed without the other falling out of place and the invention has particular application for the shaft of the compressor/turbine assembly in a turbine type of power plant.Type: GrantFiled: August 4, 1975Date of Patent: July 20, 1976Assignee: United Technologies CorporationInventor: Gregory S. Wilson
