Spring-loaded gate retraction device to return a rail-road crossing gate arm

A gate retraction device to return a crossing gate arm, the gate retraction device comprising:

• a frame to hold a gate pivot pin that is configured to provide a bi-directional rotation of the crossing gate arm;
• a main pivot assembly that receives the gate pivot pin on one end so as to enable rotation of the main pivot assembly in a horizontal plane, wherein the main pivot assembly comprises a first side and a second side opposite of the first side and wherein the main pivot assembly further comprises a spring pin extending on the first side and the second side of the main pivot assembly;
• and
• a spring-loaded assembly trapped against the spring pin of the main pivot assembly as the main pivot assembly rotates, wherein the frame further comprising:
• a first end plate angled rearwards towards the centerline of the spring-loaded gate retraction device to receive the first end of the first spring;
• a second end plate angled rearwards towards the centerline of the spring-loaded gate retraction device to receive the first end of the second spring;
• a first clip and a second clip;
• a first centering washer coupled to the first end plate to hold position of the first spring with the first clip by keeping the first spring from moving on the first end plate;
• and
• a second centering washer coupled to the second end plate to hold position of the second spring with the second clip by keeping the second spring from moving on the second end plate,
• wherein the first spring and the second spring are a coil spring, and
• wherein the main pivot assembly further comprising:
• a roller assembly including a yoke and a roller such that a pin going through the yoke holds the roller assembly in place.

A spring-loaded gate retraction device to return a rail-road crossing gate arm, the spring-loaded gate retraction device comprising:

• a frame to hold a gate pivot pin that is configured to provide a bi-directional rotation of the rail-road crossing gate arm;
• a main pivot assembly that receives the gate pivot pin on one end so as to enable rotation of the main pivot assembly in a horizontal plane substantially parallel to a ground surface of a road,
• wherein the main pivot assembly comprises a first side and a second side opposite of the first side,
• wherein the main pivot assembly further comprises a pin extending on the first side and the second side of the main pivot assembly,
• wherein the pin having a first length on the first side of the main pivot assembly and a second length on the second side of the main pivot assembly, and
• wherein the main pivot assembly further comprises a roller assembly including a yoke and a roller such that a pin going through the yoke holds the roller assembly in place;
• a first spring having a first end and a second end, the first spring is disposed horizontally lengthwise on the first side of the main pivot assembly and coupled to the frame on the first end of the first spring and detachably coupled to the first length of the pin of the main pivot assembly on the second end of the first spring;
• and
• a second spring having a first end and a second end, the second spring is disposed horizontally lengthwise on the second side of the main pivot assembly and coupled to the frame on the first end of the second spring and detachably coupled to the second length of the pin of the main pivot assembly on the second end of the second spring.

• a spring-loaded assembly trapped against the spring pin of the main pivot assembly as the main pivot assembly rotates;
• a rubber spring;
• and
• a ramp having a detent such that the roller of the roller assembly fits into the detent, wherein when a force is applied to the rail-road crossing gate arm the rubber spring is compressed in order for the roller to move out of the ramp and compress one of the first spring or the second spring, wherein the frame further comprising:
• a first channel and a second channel, wherein each channel of the first and second channels having a first flange and a second flange such that a pivot point of the gate pivot pin is closer to the first flange of the first channel,
• wherein the gate pivot pin provides a 60 degree rotation in a left direction from a home position of 0 degree and a 60 degree rotation in a right direction from the home position, and
• wherein the crossing gate arm is detachably coupled to the main pivot assembly such that the rail-road crossing gate arm is removable from the main pivot assembly so that the main pivot assembly can swivel during arm maintenance.
