Gate regulator
First Claim
1. A method of controlling the swinging of a gate in a box comprising the steps of:
- a. swinging the gate without restriction from a closed position to an open position;
b. controlling the gate to swing from the open position to a release position; and
c. swinging the gate freely from the release position to the closed position by;
i. providing a fluid cylinder having a cylinder pin;
ii. receiving the cylinder pin in a selected one of a first and second slots of an L-shaped slot when the gate swings from the open position toward the closed position; and
iii. releasing the selected slot of the L-shaped slot from the cylinder pin when the gate is at the release position thereof by;
i. providing a trip lever and a stop arm on the cylinder pin;
ii. contacting the trip lever with the box, and contacting the stop arm with the mounting plate; and
iii. holding the cylinder pin stationary relative to the box, and sliding the selected slot over the cylinder pin until the junction of the L-shaped slot is at the cylinder pin and thereby releases the selected slot from the cylinder pin.

Abstract
A gate regulator assists in unloading agricultural material from forage boxes by enabling a box gate to swing open without restriction, but the controlled the gate for slow swinging closed. At a gate release position, the gate regulator releases control of the gate so it swings freely by gravity from the release position to the closed position, and the freely swinging gate has enough momentum to relatch the gate closed. The gate regulator includes a fluid cylinder with a cylinder pin that is received in an L-shaped slot on the gate. During controlled swinging closed, the cylinder pin is within one of the slots of the L-shaped slot. At the gate release position, the junction of the two slots is at the cylinder pin, which then has room to move freely in the other slot and release the slot from the cylinder pin.
