20110113690 | SYSTEM AND METHOD FOR SERVICING A BREAKAWAY GATE - Some methods include rotating a crossing gate actuator around a vertical swing pivot of a crossing gate mount, along a vertical swing path and into a down position to block a path such that a crossing gate coupled to the crossing gate actuator blocks the path, with a spring biased crossing gate release mechanism maintaining the crossing gate in a center position blocking the path and decoupling a bar segment from the crossing gate to decouple a spring from biasing the crossing gate into the center position such that the crossing gate is free to swing around a horizontal swing pivot, perpendicular to the vertical pivot, and out of the path. | 05-19-2011 |
20130031839 | MULTIPLE DIRECTION RAILROAD GATE RELEASE MECHANISM - An example includes an apparatus for releasing a railroad gate in at least two directions. The example includes a primary pivot member and a secondary pivot member pivotally connected to the primary pivot member, with one end of the railroad crossing connectable to the secondary pivot member. In the example the primary pivot member is rotable around a primary pivot of the apparatus, the primary pivot member rotable in a first direction against a first spring bias and in a second direction, opposite the first direction, against a second spring bias other than the first spring bias, and | 02-07-2013 |
20140290004 | MULTIPLE DIRECTION RAILROAD GATE RELEASE MECHANISM - A multiple direction railroad gate release mechanism which is attached between the mount arms of a railroad gate actuator and a crossing arm to prevent breakage of the crossing arm due to impingement in either a frontal or rearward direction by a vehicle or other outside force. A primary pivot arm assembly allows a released movement of the crossing arm in reaction to frontal impingement and returns the crossing arm to the original and detent position subsequent to an impingement in order to maintain grade crossing protection. Spring assemblies, a shock absorber and a spring centering assembly act to return the primary pivot arm assembly and attached crossing arm to a normal detent position. A secondary pivot arm assembly is secured to the primary pivot arm assembly whereby the secondary pivot arm assembly can act independently of the primary pivot arm assembly to allow released movement and return of the crossing arm in reaction to rear impingement. | 10-02-2014 |

20150285137 | DEVICE FOR DRIVING AN ANCILLARY UNIT OF AN INTERNAL COMBUSTION ENGINE - A device for driving an ancillary unit of an internal combustion engine includes the ancillary unit having a mechanical drive, joined to a first coupling section, and an electric drive having a rotor and a stator with windings. The rotor is joined to a second coupling section and non-rotatably to a shaft. The shaft is joined to a component of the ancillary unit to be driven. The rotor is movable axially along a lengthwise extension of the shaft and axially with respect to the shaft. The first and second coupling sections are movable relative to each other by means of the axial movement of the rotor so as to either join together or separate the mechanical drive and the rotor, the rotor being movable axially along the lengthwise extension of the shaft with respect to the shaft in such a way that an electric current flows through the windings. | 10-08-2015 |
