Abstract: A gauge system for measuring underbite and overbite in ruminants includes a set of elongated generally S-shaped underbite gauge members and an underbite-overbite gauge member of unitary construction, each having an elongated handle portion configured to be gripped in the hand of a user, a first curved portion formed at one end of the handle portion and a second curved portion formed at the opposed end thereof, extending in vertically opposed relation to one another. The first and second curved portions of the underbite gauges and the first curved portion of the underbite-overbite gauge terminate in an underbite measuring tip of different thicknesses for measuring an underbite condition. The second curved portion of the underbite-overbite gauge has a flat rectangular overbite measuring tip that extends forward a distance from the second curved portion and is provided with a metric scale for measuring an overbite condition.

Abstract: A gauge system for measuring underbite and overbite in ruminants includes a handle having a spring biased retainer pivotally mounted thereon and a head portion at a front end having a tip receiving aperture, a set of interchangeable underbite measuring tips for use with cattle, a set of interchangeable underbite measuring tips for use with sheep, and a overbite measuring tip. The rear portion of the tip retainer is depressed by a user's thumb to pivot the front portion of the tip retainer upwardly to an open position and expose the tip receiving aperture for insertion or removal of a selected underbite measuring tip, or the overbite measuring tip, and thereafter removing the thumb allows the front portion of the tip retainer member to be lowered under spring pressure to the closed position and retain the selected underbite measuring tip, or the overbite tip in the aperture.
