Abstract: A rotating latch assembly includes a lift housing extending between a first opened end and a second opened end and defining a chamber extending therebetween. A support tube is slidably disposed in the chamber and extends between a first end and a second end. The lift housing is movable along the support tube between an extended position and a lowered position in response to a movement provided by an actuator wherein the extended position is the lift housing being adjacent to the first end and the lowered position is the lowered position being adjacent to the second end. A retaining member is disposed between the lift housing and the support tube and attached to the support tube and the lift housing for maintaining the lift housing in the extended position as the lift housing moving from the lowered position to the extended position.
Abstract: An adjustable transition duct support system for a transition duct that channels hot gases from a combustor exit to a gas turbine inlet of a turbine engine. The adjustable transition duct support system includes an adjustable forward transition flexible support assembly in contact with a transition duct body, whereby the forward transition flexible support assembly may be formed from a base extending toward the transition duct body and first and second side support arms extending from the base to the transition duct body. The first and second side support arms may be formed from a plurality of flex plates spaced from each other with spacers that provide rigidity in circumferential and radial directions and flexibility in an axial direction. The number of flex plates used may be varied to accommodate different turbine engines. The adjustable transition duct support system may have natural frequencies for circumferential and radial modes above two engine orders.

Abstract: A pneumatic fore-aft vibration isolator lock system (and method) is provided. The innovation provides a locking action through the use of pneumatically-actuated spring pressure to lock or unlock the isolation system. In one aspect, to unlock, air pressure is applied and the spring pressure is overridden by the air pressure. By overriding the spring pressure, plates are moved thereby unlocking the isolator. The system can allow for one touch, fingertip locking and unlocking of the fore/aft isolation system.

Abstract: Load stabilizing inserts for a motor vehicle. The inserts include a base plate, a top plate spaced apart from and angularly pivotable with respect to the base plate, and one or more contact plates. The insert is sized and shaped for insertion between an overload spring and a spring pack in a motor vehicle such as a pickup truck. Four load stabilizing inserts may be installed to provide stable operation of the pickup truck when loaded at or near the maximum design gross operating weight of the vehicle. During those periods when the truck is not loaded, such as when a truck camper is not installed, the load stabilizing inserts may be angularly adjusted and secured in an open, non-working position, to provide a relatively soft ride during such position.
Abstract: A curved portion, with a curved cross section, is formed at the recess of the pad. The curved portion has a contact portion which contacts the leaf spring's tension surface, which faces the curved portion. The curved portion's thickness decreases from the contact portion to an end portion of the curved portion, thereby being spaced from the leaf spring's tension surface. In the pad, the height of the curved portion of the recess is set such that contact of the leaf spring's tension surface and the corner portion of the end portion of the curved portion can be avoided when the stroke length of the leaf spring's end portion is at maximum. Thus, the tension surface of the leaf spring is not worn by the corner portion of the end portion of the curved portion. As a result, breakage of the leaf spring caused by wear can be prevented.
Abstract: A suspension assembly includes at least one leaf spring with first and second spring ends that are adapted for mounting to forward and rearward vehicle frame portions, respectively.

Abstract: The arrangement comprises mounting supports for the spring slats, insertable in the longitudinal beams of the bedstead, with two upper spring-slats serving as a support for the mattress and undulating spring-slats situated below them. A tiltable holding part having four receptacles for the spring-slats is fitted on a plug of the mounting support. Below the plug there is a resilient bearing pad enabling the holding part to deflect vertically. The upper spring-slats are bent convexly upward and have a broadened cross-section in the middle. By means of the undulating lower spring-slats, a progressive spring action is achieved. There is no sagging of the mattress in the region of heavier parts of the body, optimum spring action being ensured nonetheless. It is possible to divide the bedstead into zones of differing degrees of firmness by selectively providing mounting supports with only upper spring-slats or with additional lower spring-slats.
Abstract: A railway track working machine is equipped with a device for blocking the suspension of its axles, which device comprises, for each axle box a movable support sliding in a vertical guide fixed to the machine chassis and vertically displaced by a rod of a jack. Restoring springs ensure that the movable support bears against the rod of said jack. The movable support comprises a vertical stop, a transverse stop and two longitudinal stops intercepting during and at the end of the travel of the jack bearing members integral with the axle box in order to immobilize the latter in the vertical, transverse and longitudinal directions with respect to the chassis. This device is suitable for machines whose tools are generators of reaction forces which are capable to displace the machine chassis with respect to the railway track in the three aforementioned directions.

A movable press member positioned to face the helper spring unit and press the main spring unit against the helper spring unit is also provided. The controlling apparatus further includes a piston arrangement for pressing the press member to urge the main spring unit against the helper spring unit.
Abstract: The universal spring stabilizer of the present invention includes a unitary spring stabilizer which is universally adaptable for use with most passenger car multi-leaf type rear springs. The spring stabilizer includes integral mounting constructions which facilitate securing the stabilizer to the car spring. The universal spring stabilizer acts to add a leaf to the rear spring and by virtue of its design, functions in a manner to work against the arch of the spring. The length of spring steel of which the stabilizer is fabricated is bent to overfit the spring suspension and includes front and rear riveted cross plates which function with U-bolt connections to secure the stabilizer to the passenger car rear spring. The stabilizer is formed front and rear with two spaced pressure points to apply the effects of the stabilizer to the existing spring at four spaced pressure points, two forwardly of the axle suspension and two rearwardly of the axle suspension.

Abstract: A loading bar is mounted on a leaf spring of a racing vehicle rear axle suspension system to increase traction on the vehicle tires during acceleration. Strut tube and strap members are mounted in a spaced relationship on the vehicle leaf spring rearwardly and adjacent to the vehicle axle by a pair of U-bolts and reinforcing plates. The tube and strap members extend rearwardly from the axle and are joined at their extended ends by a wheel bracket and a strut tube adjusting channel. The strut tube extends in an upwardly angled direction between the adjusting channel and axle, with the strap member being generally parallel with respect to the ground or racetrack. A wheel or roller is mounted on the wheel bracket and is spaced above the ground when in static condition. The loading bar is readily adjustable on the leaf spring to change the traction aiding effect thereof.

One end of the shock absorber leaf spring may be fixedly attached on the housing inner periphery; the other end of the shock absorber spring is connected to a flexible chain passing around a roller in the housing and connecting with a rotatable sleeve which has a cam surface about which the chain can be wound. An elongated steel leaf spring is connected by a flexible belt to both the outer periphery of the housing and to a wheel and axle means. The chain winding sleeve is rotated about its associated shaft for adjusting the tension on the belt for proper shock absorber cushioning effect. The cylindrical shaped housing is held on the supporting sleeve by an adjusting and locking nut.
