Patent number: 11491408Abstract: A bogie configured to move along a track of an amusement ride includes two first lateral wheels, on each side of a vertical center plane of the bogie, for rolling along a run of the track. A second lateral wheel is mounted on each side of the vertical center plane and is movable perpendicular to the vertical center plane between a first position proximate the vertical plane and a second position spaced-away from the vertical plane. The bogie also includes a mechanism that provides a force to normally bias the second wheel toward the first position. The mechanism is configured such that the magnitude of the provided force increases with increasing separation between the second lateral wheel on one side of the vertical center plane and the second lateral wheel on the other side of the vertical center plane.Type: GrantFiled: April 27, 2020Date of Patent: November 8, 2022Inventors: Richard Martin, Jeffrey Beaudin, Robert Lockhart, William Nathaniel McNair, Derek Coopman, Brian Richard Gill, David Anthony Barlow, David Roy

Patent number: 5111751Abstract: Transport means are clamped to a movable rope (6) with a clamp capable of coupling. The clamp exhibits clamping jaws (4, 5), where one of the clamping jaws (5) can be pressed against the rope (6) based on the force of a spring (14). This clamping jaw (5) can be lifted off the rope (6) again with a spatially fixedly disposed connecting link. The movable clamping jaw (5) is formed as a two-arm lever, where the one arm of the two-arm lever forms the clamping jaw (5), and where the second arm (9) of the two-arm lever is loaded by a spring (14). An angle lever (10) is hinged at the two-arm lever (8) in such a way that the spring (14), furnishing the clamping force, is released upon opening of the clamp, as illustrated in FIG. 1.Type: GrantFiled: November 25, 1988Date of Patent: May 12, 1992Assignee: Felix Wopfner KGInventor: Rudolf Zlotek

Patent number: 4957047Abstract: The revolving cable transport installation, for instance a gondola aerial cableway, has the carriages of the gondolas supported upon two adjacently extending support cables. Between both support cables there is arranged a continuously revolving traction cable. Along the travel path the carriages are coupled with the continuously revolving traction cable by actuatable cable clamps. These cable clamps are connected with the carriages so as to be elevationally movable and they engage the traction cable from below. The traction cable extends at the upper region of the carriages and can support itself within the suspension zones, i.e. between the support masts at the carriages. Thus, the weight of the traction cable does not load the cable clamps and these cable clamps can accommodate themselves to the position of the traction cable independent of the carriages.Type: GrantFiled: October 27, 1989Date of Patent: September 18, 1990Assignee: Von Roll Transportsysteme AGInventors: Fritz Feuz, Walter Brawand

Patent number: 4860664Abstract: An aerial tramway grip assembly (21) including a gripping head (24) carrying a pair of opposed movable jaws (26, 27) for gripping a haul rope (23) and a resilient biasing assembly (37) biasing the jaws (26, 27) towards a closed position. The improvement in the grip assembly (21) is comprised of two pairs of opposed stationary gripping surfaces (41,42,43,44) positioned proximate the jaws (26,27) and positioned to cooperate with an opposed one of the jaws (26,27) to grip the haul rope (23) therebetween in the event of release of the gripping force provided by the other jaw. Additionally, resilient biasing is provided by two independent rubber blocks or cylinders (38,39) which bias each jaw (26,27) toward an opposed jaw and toward the opposed stationary gripping surface (41-44). The stationary gripping surfaces (41-44) additionally are oriented to be gravity biased into wedging engagement with the haul rope (23) so as to grip the haul rope (23) even in the event of failure of the movable jaws (26,27).Type: GrantFiled: April 20, 1988Date of Patent: August 29, 1989Assignees: Zygmunt A.

Patent number: 4658733Abstract: A haul rope grip assembly for an aerial tramway is disclosed which is suitable for both detachable and permanent gripping of the tramway haul rope. The assembly includes a gripping head having a pair of relatively spaced apart converging haul rope gripping surfaces oriented for gravity biasing of the surfaces into wedging engagement with the haul rope under loading of the grip. Additionally, the assembly includes a jaw positioned proximate the surfaces and formed to apply supplemental force to the haul rope in a direction tending to further wedge the haul rope between the gripping surfaces. The jaws are also formed to unwedge the haul rope upon movement from a closed to an open position. In the detachable grip assembly, a pair of independently movable jaws pivotally mounted and actuated by levers are biased closed with leaf springs that are spaced apart to allow for a hold down sheave.Type: GrantFiled: August 19, 1985Date of Patent: April 21, 1987Inventor: Jan K.

Patent number: 4633783Abstract: On the main shaft (2) of a clamping device (1), a guide-pulley (14) is provided. At the end of the main shaft, an inner clamping jaw (3) is rotatably mounted. An outer clamping jaw (7) is hinged to the inner clamping jaw (3) and connected rotation-fast to an upper frame part (6) of the clamping device. On the outer clamping jaw (7), a stop component (9) is provided. For opening the clamping jaws (3, 7), an actuating roller (10) is pressed downward, the outer clamping jaw being brought into a lower position against the pressure of a spring (21) disposed on the main shaft (2). Simultaneously the inner clamping jaw (3) rotates about the swivel joint (11) situated at the end of the main shaft (2). For closing the clamping jaws, the actuating roller (10) is moved back into its upper position. The clamping device, especially for use in cableways, requires only a few parts, which are suitable as modules both for single and for multiple couplings.Type: GrantFiled: June 24, 1985Date of Patent: January 6, 1987Assignee: Von Roll Habegger AG.Inventor: Fritz Feuz
