  • Patent number: 4350228
    Abstract: The actuating device comprises an actuating nut and spindle combination disposed in a brake piston, the spindle being rotated by an actuating lever and the nut having an outer thread engaging an inner thread of the brake piston thereby providing a brake pad clearance adjusting device. The brake piston is rotatably connected to the spindle via a one-way clutch for progressively screwing the brake piston out of the nut to compensate for brake pad wear. The one-way clutch is connected to the spindle by a rod extending through an axial bore in the spindle enabling the clutch to be unlocked from the outside of the actuating device for resetting the brake piston when worn brake shoes are being replaced.

  • Patent number: 4347917
    Abstract: A floating type of disc brake is constructed with a fixed member which slidably supports a floating caliper member. The fixed member has two pairs of arm portions which span a rotatable disc and are displaced about the periphery thereof on either side of the floating caliper member. The floating caliper member is provided with a hole for receiving a bolt extending in the axial direction of the disc from one pair of the arm portions and a pin slidingly fitted in a guide slot running in the axial direction of the disc in the other pair of arm portions. The pin and guide slot are provided outside the circumference of the disc so that the floating caliper member can be rotated thereabout when the bolt is removed to facilitate replacement of the friction brake pads. The range of sliding movement of the bolt relative to the hole is displaced in the axial direction of the disc from the range of sliding movement of the pin relative to the guide slot.

  • Patent number: 4345537
    Abstract: An apparatus for restraining and berthing a floating body or vessel on a water surface at a quay wall, comprises a driving subsystem, a movable member driven by the driving subsystem and forwardly and backwardly guided by guide members, and an elastic end piece such as a marine fender secured to the movable member and projecting away from the quay wall. The apparatus according to the invention can exactly move the end piece to a desired position for restraining the floating body and can utilize precompressive forces arising in the end piece, thereby accommodating tolerances or unintensional errors of the quay wall in construction and absorbing rocking energy of the floating body to hold it firmly in place in a harbor. The apparatus according to the invention retracts its elastic piece in a rest or inoperative position and extends it in an operative position to be in contact with a floating body such as a ship or boat to serve as a marine fender.

  • Patent number: 4344512
    Abstract: A duo servo drum brake includes a pair of brake shoes which are movable by a hydraulic actuator during a service brake application to a braking position in engagement with a rotatable member. A strut and parking lever are engageable with respective brake shoes to separate the same during a parking brake application. In order to control a running clearance between the pair of brake shoes and the rotatable member, an extendible assembly is disposed between the pair of brake shoes opposite the hydraulic actuator. The extendible assembly is also responsive to a parking brake application to expand the pair of brake shoes into engagement with the rotatable member.

  • Patent number: 4343055
    Abstract: The invention refers to a device for supporting a first member which is rotatable about a mainly vertical axis on a second member. The invention is primarily intended to be used for supporting very large members, which carry very heavy loads. The device incorporates two race tracks and a plurality of rollers cooperating therewith. In order to avoid sliding movements in the contact between roller and race track at varying loads and for achieving an even load distribution on all rollers, the rollers at least of one of the rows of rollers are resiliently suspended in support members, which are adjusted thus that the rollers will engage their associated race track under preload. The rollers and/or the race tracks may be cambered or the support members may be displaceable in the longitudinal direction of the rollers and contact the adjacent elements via arc-formed supporting surfaces for achieving a pure rolling movement in the contact between roller and race track due to race track movements.

  • Patent number: 4343588
    Abstract: The previous linkages for transmitting signals across an axis (21) between a first member or cylinder (20) and a second member or frame (11) have been relatively difficult to adjust and have had a tendency to bind. Herein, a roller (44) is pivotally mounted to a first link structure (36) which is itself pivotally mounted relative to the cylinder (20). The roller (44) defines a generally circular cam surface (42). A second link structure (52) is mounted to the frame (11) and a generally U-shaped member (98) has one of its legs (100) mounted to the second link structure (52) and the other leg (102) positioned to define a coacting surface (106) for action against the roller (44). An adjustment device (122) serves for adjusting the other leg (102) of the generally U-shaped member (98) tangentially and radially relative to the roller (44). Relatively straightforward and easily accessible adjustment is thereby provided. Also, binding problems are reduced.

  • Patent number: 4342448
    Abstract: A gas-operated piston cylinder assembly arranged between upper and lower die members of a press. The lower end of the cylinder communicates with a source of high pressure gas and also communicates through a passageway with the upper rod end of the cylinder which is sealed from the surrounding atmosphere. The piston rod has a cross sectional area only slightly smaller than the piston. The passageway between the lower and the upper ends of the cylinder contains a lubricant impregnated member and a by-pass controlled by a check valve which allows gas flowing from the rod end of the cylinder to the lower end thereof to bypass the lubricant impregnated member.

  • Patent number: 4340005
    Abstract: An assembly for feeding the luff of a jibsail into a grooved foil mounted on the headstay of a sailboat comprises a grooved feeder and prefeeder adapted to be removably mounted on the headstay. The feeder comprises a pair of interfitting spline members adapted to be assembled together by relative sliding movement along paired guideways to freely encircle the headstay and to confine the lower end of the foil therebetween and to be clamped to the latter and to each other as a unitary element by a single attachment means, such that the grooves of the feeder and foil are rigidly maintained in alignment. The prefeeder comprises a guide slidably and universally pivotal on the headstay at a location below the feeder and having a luff receiving opening through which the luff of the sail may be fed and guided to the grooved feeder and thence to the grooved foil.

  • Patent number: 4340004
    Abstract: A high-speed ship of the displacement hull type which is adapted to float in a raised position, with the waterline being at a lower position. Greater buoyancy is caused by high-pressure air being held between the bottom plating of the ship and the water flowing under the bottom plating thereby reducing the wave-making drag of the bow and thereby allowing for the ship to have increased capability.

  • Patent number: 4336867
    Abstract: A drum brake assembly includes a pair of brake shoes which are carried by a backing plate and engageable with a hydraulic actuator. The hydraulic actuator is operable to move the pair of brake shoes from a rest position to a braking position. A strut extending between the pair of brake shoes cooperates with a parking arm to move the pair of brake shoes to the braking position during a parking brake application. A support assembly on the backing plate is disposed opposite the hydraulic actuator for the purpose of absorbing braking torque developed by the pair of brake shoes. The support assembly comprises a pair of slots and a lever. The lever is movable in response to movement of the parking arm to adjust the position of the pair of blocks relative to each other. In a first position the blocks are in abutment with the backing plate while in a second position the blocks are free to move a limited amount relative to the backing plate.
