Abstract: A box spring assembly which includes a generally rectangular frame and a plurality of wire springs mounted on the frame and connected to each other so as to yieldably resist downwardly directed bedding loads. Each of the springs has an elongated body portion arranged above the frame and downwardly extending end portions, each of the end portions having a lower column section consisting of a straight length of spring wire and an upper section consisting of a plurality of substantially horizontal torsion bars and a plurality of angularly arranged connecting bars connected to and extending between the torsion bars so that in response to a downwardly directed bedding load, the upper section will yieldably collapse to accommodate the load and impart a feeling of soft support to the bedding user. The straight wire column is inclined inwardly so that it can bend slightly and cause a twisting of the torsion bar on which it is mounted. This action imparts a feeling of firm support to the bedding user.

Abstract: A torsional damper integral with a torsion bar wherein the damper is not directly connected to any support structure. Torque applied by the torsion bar to the damper on one side of the damper's mid length is equilibrated by torque exerted by the torsion bar to the damper on the opposite side of its mid length. In this manner, a part of the torsion load is transmitted to the energy dissipating damper.

Abstract: The device includes a rigid stay-bar which is bent so as to reproduce approximately the shape of the forward part of the boat, at least one of the ends of which is connected to a torsion-bar fixed onto the grating and arranged transversely with respect to the boat. The bent central portion of the stay-bar rests against a rigid bearing surface integral with the forward portion of the boat. The stay-bar ensures the holding in position of the forward portion of the boat due to the elastic force exerted by the torsion-bar, which opposes the forces exerted by the waves to lift the forward portion of the boat.

Abstract: A bar-shaped torsion spring, such as a torsion bar or a stabilizer. The spring is made with a hollow interior main body. Linking mechanisms and fixing portions are formed integral with or connected to both ends of the main body of the spring. A cover of reinforced plastics is applied to the outer circumference of the main body of the spring.

Abstract: A three-wheeled vehicle is disclosed having an improved simplified, light weight, tubular frame design which provides a U-shaped anti-sway bar for resistance to twisting of the frame and allows a steering system having a pair of front wheels to be steered by a handlebar that is mounted on a vehicle frame member beneath the seat of the vehicle operator, the handlebar curving upward and wider than the seat for convenient operation and access to the vehicle seat. The frame for the seat of the operator is provided by the anti-sway bar. The front wheels mount to the frame behind operator's feet, under normal riding conditions; steering being such that sharp turns may be made without interference between the wheels on the one hand and the frame and steering members on the other.

Abstract: A mechanical attenuating system for preventing horizontal forces from being transmitted from a base such as the ground to a structure such as a building or a nuclear reactor resting on that base. The system has two components: a vertical support which allows free relative horizontal movement between structure and base, and horizontal damping. The two can be combined into a single instrument. When the two are used separately, the support may be supplied by rubber or rolling bearings, by flexible columns or by tendons.

Abstract: The trunnion assembly includes a housing and a one-piece tubular shaft journaled within bushings secured in the housing. Thrust forces acting on the shaft in one direction are counteracted by a spacer disposed between one bushing and a hub rigidly secured to the shaft. Thrust forces acting in the opposite direction are counteracted by a multi-segmented thrust ring fitted in a groove in the shaft in position to bear against another bushing in the housing. The thrust ring is held within the groove by a retainer ring disposed between the thrust ring and an annular lip of the housing. The retaining ring, the annular lip, and a seal retainer connected to the one piece shaft by a snap ring defines a seal ring cavity having a lubricant seal ring therein that is unaffected by axial thrust acting on the shaft and prevents leakage of lubricant between the shaft and the housing at the adjacent end of the shaft. The other end portion of the shaft is sealed to the hub and housing by a conventional seal ring.

Abstract: A replaceable torsion type spring assembly or unit having a resilient elastomeric tubular member with one end of such tubular member secured to a stationary member and the other end of such tubular member secured to a member that has force applied thereto for rotating such last member. A hollow tubular member is loosely journaled internally of the resilient elastomeric tubular member to provide support to the spring assembly.

Abstract: A rotary regenerative air preheater including a housing surrounding a rotor of heat absorbent material that is adapted to rotate between a duct for heating fluid and a spaced duct that carries a fluid to be heated. Sealing means intermediate the rotor and the rotor housing include a torsion spring activated by the moving rotor that is adapted to bias the sealing means axially to provide a barrier that precludes fluid flow between the rotor and the rotor housing.

Abstract: Linear acceleration responsive apparatus is disclosed wherein a sensing mass is suspended within a housing by torsion hinge means located along a pair of parallel axes in each of two planes perpendicular to an input axis. Separate torsion hinge means in each plane are attached to the mass and the housing by ring assemblies, and are joined by intermediate arms which may serve as flex leads for carrying electric current to a force rebalance winding on the mass.

Abstract: A resilient lever assembly which incorporates spring action whereby the resilient portion of the assembly constantly urges a rigid lever against a lever movement resistance member connected to the lever. The action is accomplished by securing the resilient support to a fixed member in a rotational position such that the resilient support is stressed in the proper direction. In one form, the resilient support and its securing components comprises a rubber bushing between two sleeves, one fixed to the lever and the other to the fixed member. In another version of the invention, the resilient support is in the form of an extension of the lever having spring-like properties and secured at its outer end to the fixed member. The lever movement resistance member may be in the form of a stop adjacent the rigid lever. In another version, the lever movement resistance member could comprise the valving of a vehicle brake booster against which the lever is urged.

Abstract: A regenerator assembly for a gas turbine engine includes a center driven rotatable matrix with a hub and drive shaft including a sprocket fixedly secured thereto with a roller chain driven thereacross by means of a cross shaft assembly including a first elongated tubular coupling telescoped with respect to a low rate torsion spring bar and wherein an input shaft connected to one end of the torsion spring bar is associated with damper means including first and second relatively movable parts connected in parallel to the torsion spring bar by the coupling and operative to damp oscillations in said matrix disc drive shaft during operation of the regenerator assembly.

Abstract: A torsion bar spring suspension for the front wheels of a motor vehicle is disclosed. A continuous torsion bar spring that is formed into the shape of a closed figure has transverse portions that are situated fore and aft the axis of rotation of the front wheels and extend across the vehicle frame. The torsion bar has single loops or coils at each of the outer ends of the transverse portions and these loops are connected by resilient devices to the vehicle frame. Left and right generally Y-shape portions of the torsion bar connect left and right wheel support members to the loops at the ends of the transverse bar portions.

Abstract: A rear suspension for motorcycles which employs primary and secondary torsion springs operating on the rotative axis of the horizontally disposed and rearwardly trailing fork carrying the powered traction wheel. The two springs are of selected resilience and are quickly replaceable without disassembly of the suspension system, and each is adjustable for controlling the normal vehicle height and pitch attitude to be subjected to varying loads. Load application to this rear suspension system is substantially central of the vehicle and with the result that radius of gyration is minimized, unsprung weight is reduced, and with improved dynamics characterized by a spring-stop snubbing action resulting in increased traction and ground engagement capability for superior handling.

Abstract: This instrument can fulfil two purposes. It can be a torque limiter which transmits torque up to a limit set by design, without slip. At higher values of torque it behaves as an absorber of energy. It can be cyclic or unidirectional or impact in operation. It can be applied as an absorber of wind or earthquake forces, as a buffer or fender in a transport system, as a brake, or as a torque limiter in a shaft transmitting power. Its commonest form is an eccentric within a cylinder, the intervening space being filled with a material capable of spontaneous recovery and recrystallisation at the working temperature.

Abstract: A bicycle handlebar shock absorber for use with conventional handlebar support brackets, comprising a curved strip of flexible material which is adapted at one end thereof to be fixedly mounted on the head of the support bracket and at the other end thereof to be fixedly attached to the handlebar itself on both sides of the bracket clamp supporting the handlebar. With the shock absorber mounted on a bicycle, the bracket clamp is adjusted to allow rotational, but not radial, movement of the handlebar, and the flexible strip of the shock absorber acts as a torsion spring to dampen rotational movement of the handlebar induced by travel of the bicycle over rough terrain.
