| 104249000 | CAR STOPS | 10 |
| 20090031914 | Backward Motion Stop - A backward motion stop for a car to be pulled up in a guiding device is provided and consists of a catch lever engaging in a catch rail such that it operates noiselessly. For this purpose, an induction strut is laid parallel to the catch rail and the catch lever is equipped with a magnet interacting with the induction strut so that a linear eddy current brake is formed, which exercises a slight braking force counteracting the upward motion of the car upon the catch lever, which, because of the torque linked therewith, is moved out of the catch rail, so that it essentially floats over the catch rail. | 02-05-2009 |
| 20100083865 | Devices and Systems for Controlling Travel of a Railcar - A device and system for controlling travel of a railcar along a set of rails is provided. In one example, a railcar stop is coupled to the set of rails and is selectively movable between a first position wherein the railcar is free to travel along the set of rails and a second position wherein the railcar stop engages the treads of the wheels to thereby prevent travel of the railcar in at least one direction along the rails. | 04-08-2010 |
| 20110120340 | Anti-Roll Back Assembly with Linear Magnetic Positioning - An anti-roll back (ARB) assembly for use with vehicles that ride on a track, which has inclined portions that include a set of ARB or lift pins. The assembly includes a linear magnet assembly positioned along the track in the ARB portion, and this assembly includes spaced apart magnet arrays that define a slot or elongated magnetic force zone. The ARB assembly includes an ARB element with a body pivotally supported on a vehicle frame and further includes an electrically conductive reaction plate supported on the vehicle frame, and the plate passes through the magnet assembly slot when the vehicle travels on the track. The reaction plate is connected to the ARB body to pivot it in response to displacement of the reaction plate in response to magnetic forces to rotate it up into a suspended position in which the ARB body is spaced apart from the ARB pins. | 05-26-2011 |
| 20110232521 | Devices and Systems for Stopping Travel of a Railcar - Devices and systems for stopping travel of a railcar along rails is provided, the railcar having wheel treads that ride on the rails. A railcar stop is configured to engage at least one wheel tread of the railcar to stop travel of the railcar along the rails. The railcar stop extends above the rails at a first height prior to engagement with a wheel tread and extends above the rails at a second, greater height after engagement with the wheel tread. | 09-29-2011 |
| 20130305955 | TRANSPORTING SYSTEM - The invention relates to an in-house track-bound transporting system with self-propelling carriages that move on rails. The system has stoppers to prevent said carriages from crossing over open rail ends or track borders, and the system is provided with stops. The stoppers collide with the stops in order to prevent a crossing-over, said stops having first and second fixed stop elements. The stoppers can be moved between a first crossing-over position and a second crossing-over position such that the first stop elements can be crossed over in the first crossing-over position of the stoppers, and the second stop elements can be crossed over in the second crossing-over position of the stoppers, wherein the first stop elements cannot be crossed over in the second crossing-over position of the stoppers, and the second stop elements cannot be crossed over in the first crossing-over position of the stoppers. | 11-21-2013 |
| 20150122144 | SYSTEM AND APPARATUS FOR SILENT ANTI-ROLLBACK FOR TRACK MOUNTED VEHICLES - An anti-rollback apparatus includes a lock arm, a rod, a pawl, a wheel, and a one-way bearing. The rod member is pivotably coupled to the lock arm and the pawl and one-way bearing are coupled to the rod member. The pawl is shaped to selectively engage teeth on a an anti-rollback plate. The wheel is configured to roll on a surface of the anti-rollback plate. The one-way bearing couples the wheel to the pawl. The one-way bearing allows the wheel to rotate freely in a first direction and locks the wheel in relation to the pawl when the wheel rotates in a second direction to force the pawl to engage the teeth. | 05-07-2015 |

| 20100024677 | GEAR SWITCH AND TROLLEY STOP FOR A CONVEYOR ASSEMBLY - A switch assembly for a conveyor is provided. The switch assembly includes a rail section forming a portion of the conveyor assembly. The switch assembly has a first gear assembly pivotable about a first pivot axis and carrying a first gate and a second gear assembly pivotable about a second pivot axis and carrying a second gate, the second pivot axis being positioned below a plane extending perpendicular to the rail section from the first pivot axis. A trolley stop assembly for a conveyor is also provided. The trolley stop includes a body having a first side portion and a second side portion arranged to be disposed on first and second sides of a rail section. A pivot member extends through the body and at least a portion of the rail section. A stop member is carried by an upper portion of the body and a weighted member is also carried by the body arranged to position the stop member for engagement with a trolley. A conveyor assembly including a switch assembly and trolley stop is also disclosed. | 02-04-2010 |
| 104257000 | Displaceable chock | 2 |
| 20120055368 | Devices and Systems for Controlling Travel of a Railcar - A device and system for controlling travel of a railcar along a set of rails is provided. In one example, a railcar stop is coupled to the set of rails and is selectively movable between a first position wherein the railcar is free to travel along the set of rails and a second position wherein the railcar stop engages the treads of the wheels to thereby prevent travel of the railcar in at least one direction along the rails. | 03-08-2012 |
| 20150007743 | DEVICES, SYSTEMS AND METHODS FOR ENGAGING AND DISENGAGING RAILCAR WHEELS AND FOR CONTROLLING TRAVEL OF RAILCAR - Devices, a system and a method for controlling travel of a railcar along a set of rails are provided, the railcar having wheel treads that ride on the rails. A railcar stop is selectively movable between a first position wherein the railcar is free to travel along the rails, and a second position wherein the railcar stop is configured to engage the tread of the at least one of the wheels to thereby stop and prevent travel of the railcar in at least a first direction along the rails. The railcar stop is further configured to he selectively movable in the first direction along the rails from the second position to a third position to thereby disengage the railcar stop from the tread of the least one of the wheels. | 01-08-2015 |
| 104259000 | Sliding | 1 |
| 20120012027 | STOP DEVICE FOR RAIL CARS AND IN PARTICULAR FOR USE WITH TRACKS IN CLASSIFICATION YARDS - A device for stopping rail cards includes an articulated member adapted to move between a first raised position in which ait receives a rail car wheel in contacting or abutting relationship to cause effective stopping of the car, and a second retracted position which offers no resistance to movement of the car wheels. A hydraulic or pneumatic ram is provided to move the articulated member between the two positions. | 01-19-2012 |
