Patent number: 4500112Abstract: A suspension assembly for supporting a vehicle chassis from at least one vehicle axle is adapted for use on a steering axle and includes an integrally formed stool type axle seat with an outrigger extension member extending into the wheel well area, an inner extension member with bracket members to pivotally attach a sway bar, and a lower extension member with bracket members to pivotally attach a pair of torque rods. An upper frame extension member extends into the wheel well area and aligns with the outrigger member of the stool axle seat so that an air spring may be mounted and extend between them. A hanger assembly is mounted forwardly of the axle seat and has a U-shaped bracket to pivotally support the forward end of each of the two torque rods.Type: GrantFiled: June 22, 1983Date of Patent: February 19, 1985Inventor: John E.

Patent number: 4494771Abstract: A first embodiment of a suspension supports a vehicle from a drive axle and includes a forward hanger and a rearward hanger depending downwardly from the chassis, an axle seat assembly attaching the suspension to the axle, a first torque arm pivotally connected between the axle seat asssembly and the forward hanger, a second torque arm pivotally connected between the axle seat assembly and the rear hanger, a central elastomer spring mounted between opposing surfaces of the torque arms, and an upper radius rod pivotally connected and extending between the forward hanger and axle seat assembly to form a parallelogram with the first torque arm to control and stabilize the axle. A second embodiment of the same suspension mounts a vehicle chassis to a steer axle with the radius rod being offset inwardly and the axle seat being mounted to the top of the steer axle to accommodate space limitations.Type: GrantFiled: August 17, 1983Date of Patent: January 22, 1985Inventor: John E. Raidel

Patent number: 4494728Abstract: O-rings, which are disposed within pneumatic couplings and which are recurrently moved past ports within those pneumatic couplings, tend to be abraded as they recurrently engage the changes of surface at the mouths of those ports. The present invention minimizes the abrading of the O-rings by providing the ports with bell mouths which merge smoothly into at least two spaced points on the surface of the body in which the ports are located.Type: GrantFiled: June 7, 1982Date of Patent: January 22, 1985Assignee: Foster Manufacturing CompanyInventor: Lee H. Cruse

Patent number: 4492323Abstract: A pitcher for pouring water or other liquids having a container portion. A lid is hinged at the top of the container portion allowing pivoting of the lid between an open position for access to the interior of the container and a closed position for covering same. A spout is located at the hinge, and a handle is located at the side of the pitcher opposite the spout and hinge, whereby the contents are poured, and the lid opens, in a direction away from the handle. There is also included a flap at the spout opening which is mounted for swinging movement between a closed position with the pitcher upright, and an open position with the pitcher tilted for pouring.Type: GrantFiled: November 9, 1981Date of Patent: January 8, 1985Assignee: Gateway Plastics, Inc.Inventor: R. Eric Essen

Patent number: 4489987Abstract: A mine tool bit is retained in an open ended block with a cylindrical button insert transversely mounted in the shank of the bit, the insert having a cylindrical button extending radially outwardly from the shank and biased by a coil spring. The button must be manually depressed to insert or remove the bit from the block.Type: GrantFiled: April 18, 1983Date of Patent: December 25, 1984Inventors: John E. Towers, Robert E. Edwards

Patent number: 4486029Abstract: A first embodiment of a leaf spring suspension assembly for a tractor trailer or the like having single or multiple axles includes a first and second hanger with a camelback spring slidingly secured to an axle bracket assembly with a single torque rod extending between the forward hanger and the axle bracket assembly to stabilize same and prevent axle wind up or wheel hopping. In a multiple axle vehicle, a pivoting type equalizer is mounted between leaf springs and provides the bearing support for an end of each spring. In a second embodiment, an equalizer is supported from the chassis member by an elastomeric spring member with a shock absorber dampening the oscillation thereof. The equalizer is stabilized in the fore and aft direction by a mounting bracket and web assembly within which the mounting bracket extends, and a telescoping tube assembly vertically aligned and surrounding the shock absorber to permit vertical movement but restrict fore and aft movement of same.Type: GrantFiled: July 8, 1983Date of Patent: December 4, 1984Inventor: John E. Raidel

Patent number: 4484623Abstract: A coiled heat exchanger utilizing a sandwich plate type construction with a plurality of spot welds equally spaced throughout, the plate being inflated to expand the passageways therebetween, has fluid tight connections feeding through the outside of the coil for accessing both passageways adjacent and opposite the center divider plate. One or more arcuate slots are punched in the center divider plate and surround a spot weld, with a larger hole punched in the adjacent outer plate and a tube welded against the divider plate to seal the arcuate slot and form a fluid connection between the passageway opposite the divider plate and the outside of the coil.Type: GrantFiled: April 8, 1983Date of Patent: November 27, 1984Assignee: Paul Mueller CompanyInventors: David W. Rowe, William R. Waynick

Patent number: 4481941Abstract: A hip stabilization device is adaptable to all patients, and has a hinged brace held in alignment with the hip joint by a belt adjustably engaged about the patient's waist, with the belt engaging the top of the brace. A support is adjustably engaged about the patient's thigh, and is secured to the bottom of the brace. The mounting of the upper and lower parts of the brace to the belt and support respectively are adjustable to accommodate the height and proportions of the patient. The brace prevents rotation of the hip joint and lateral motion of the leg. The range of motion of the hinge is adjustable to permit the maximum flexion consistent with the patient's injury and proper stabilization of the joint. The attachment on the belt to mount the brace is such that when the belt is turned over, it can engage a brace on the other side of a patient. The support and brace are universal to fit the patient's other leg and hip, so that the same parts can be used to support either hip joint.Type: GrantFiled: March 7, 1983Date of Patent: November 13, 1984Inventor: Thomas A. Rolfes
