Apparatus for detecting animal estrus
First Claim
1. An apparatus, adapted to be secured to the rump portion of a first animal, for indicating estrus in said first animal, comprising:
- a base means;
a pressure responsive means supported by said base means;
a linkage means interconnected with said pressure responsive means;
a release means, including a movable release member, interconnected with said linkage means and supported by said base means;
a cover means releasably engaged with said base and interconnected with said release means; and
an indicating means, mounted on said cover means and whereinsaid pressure responsive means is for powering said linkage means when said pressure responsive means is subjected to at least a predetermined pressure caused by a second animal mounting said first animal;
said linkage means is for powering said release means when said linkage means is powered by said pressure responsive means; and
said release means is for releasing said cover means from said base means and actuating said indicating means after said release means has been powered by said linkage means.

Abstract
An animal estrus detection apparatus adapted to be secured to the rump portion of a first animal, and actuated by a second animal mounting the first and thereby applying a predetermined amount of pressure thereon a depressible pin. The pin'"'"'s motion is transferred by a linkage mechanism to a release mechanism, which then disengages an outer cover causing it to fall away and deploy an estrus indicating streamer. The release mechanism may include either a pneumatic or an escapement type release timer which is powered by said linkage and which prevents said linkage from powering said release mechanism until a predetermined period of time has elapsed. The release mechanism may also include a counting mechanism which actuates the release arm only after a predetermined number of successive mountings of said first animal. A second, hydraulic timer, actuated when the outer cover is released, measures the time elapsed since the outer cover'"'"'s release.
