Abstract

A headgate has a pair of generally-upright elongated pipes spaced apart somewhat greater than the width of an animal to be restrained. The pipes are mounted for rotation, and spur gears are mounted respectively near one end of each of the pipes. A pair of elongated tubes are positioned generally inside of the pipes with the tubes being coupled to the pipes and at least an upper end portion of one of the tubes being movable with respect to its adjacent pipe but urged away therefrom. The assemblies of the other ends of the pipes and the adjacent ends of the tubes are releasably latchable into a closed condition in which the tubes are positioned between the pipes. As one basic feature, a pair of idler gears are disposed between the spur gears, with one of the idler gears being meshed with the first spur gear and the other idler gear being meshed with the second spur gear and with said idler gears also being mutually intermeshed, so that there is a complete slaving action of the pipes in rotation. As another principal feature, a lever is affixed to the restraint adjacent to a side of one of the assemblies and is swingable toward and away therefrom. An opening device is mechanically coupled between the lever and at least one of a pipe and a tube to enable a swingable opening of the one assembly by manipulation of the lever.
