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.

Dependent claims

An animal restraint comprising:

a pair of generally-upright elongated pipes spaced apart somewhat greater than the width of an animal to be restrained;
means for mounting said pipes to permit rotation of each pipe about its longitudinal axis, said mounting means orienting said pipes to diverge apart in the upward direction;
a first spur gear mounted on one of said pipes near one end thereof;
a second spur gear mounted on the other of said pipes near a corresponding one end thereof;
said spur gears being canted downwardly and outwardly from one another;
a pair of elongated tubes;
means for securing one of said tubes to one of said pipes in generally-parallel-spaced relationship;
means for coupling the other of said tubes to the other of said pipes in generally parallel-spaced relationship and with the upper end portion of said other tube being movable toward and away from said other pipe;
means for urging said upper end away from said other pipe;
means for releasably latching the assemblies of the other ends of said pipes and the adjacent ends of said tubes in a closed condition in which said tubes are positioned between said pipes;
a pair of idler gears disposed between said spur gears, with one of said idler gears meshed with said first spur gear and the other of said idler gears meshed with said second spur gear and with said idler gears being mutually intermeshed, for slaving each of said pipes to the other in rotation;
each of said idler gears being rotatable about a vertical axis with the axes of rotation of said spur gears being tilted with respect to the vertical direction;
and a spring effectively coupled between said pipes for biasing said pipes rotationally toward said closed condition.
