Overview
This patent describes a mechanically robust chute safety system that automatically closes a rear gate behind a calf while preventing harm to the animal during transition. Filed on March 25, 2022 and granted on April 30, 2024, the invention — developed by inventors based in Childress, TX — combines a trigger foot plate, a transfer rod, a spool-and-counterweight rotational force transfer, and a sleeve-pin/sleeve-channel interface to achieve controlled closing while allowing immediate disengagement if an animal is beneath the crossbar. The mechanism translates the animal’s weight into controlled spool rotation, using a counterweight to reset and regulate motion, and the sleeve design lets the crossbar swing free under upward pressure so the bovine is not trapped or crushed.
The result is a practical retrofit for manual calf chutes that addresses known safety risks with an elegant mechanical solution. The claims are drafted to cover the interplay of the foot plate, transfer rod, spool/counterweight, and sleeve interaction, reflecting careful claim construction and technical depth.
Key Features
- Weight-triggered floor plate driving a transfer rod and spool assembly
- Counterweight-driven spool for reliable reset and controlled gate motion
- Sleeve-pin safety release that prevents crushing if an animal is under the gate
- Entry ramp and spring options for smooth operation
This patent improves handler and livestock safety on ranches and training facilities and exemplifies mechanically focused innovation with clear applicability across the animal-handling industry.
