Abstract
Abstract An animal sorting device is provided wherein the animals are individually weighed in a chute which has an exit opening into two segregation areas. A pair of exit gates and control mechanism therefor allow selective blockage of the exit or alternatively direct egress of an animal from the chute into one of the two areas. The control mechanism for the exit gates allows for remote operation thereof and for securing the exit gates in a desired position such that the animals cannot reposition same. An entrance gate is also provided. The exit gates and entrance gate may be manipulated by a single operator from a single location.

Claim 1
Independent Claim
311 words
An apparatus for sorting animals comprising: (a) a chute having sides adapted for enclosing an animal and having an entrance end and an exit end; said exit end being adapted for communicating with first and second animal segregation areas; (b) weighing means associated with said chute for determining weight of an animal enclosed in said chute; (c) a first gate being pivotally connected to said chute near one side of said chute exit end; said first gate having a first operative position wherein said first gate is generally parallel to said exit end, a second operative position wherein said first gate is at an acute angle with respect to said exit end, and a third position wherein said first gate is generally perpendicular to said exit end; (d) a second gate being pivotally connected to said chute at a location spaced outwardly from an opposite side of said chute exit end; said second gate having a first operative position generally perpendicular to said chute exit end and having a second operative position wherein said second gate is generally aligned with said first gate while said first gate is in said second operative position thereof; and (e) mechanical means for selectively moving said first and second gates through the operative positions thereof; (f) whereby when said first gate is in said first position thereof, said chute enclosed animal is prevented from egressing from said chute exit end; when said first gate is in said second position thereof and said second gate is in said second position thereof, said chute enclosed animal is free to egress from said chute into said first animal segregation area; and when said first gate is in said third position thereof and said second gate is in said first position thereof, said chute enclosed animal is free to egress from said chute into said second animal segregation area.

An apparatus for sorting animals comprising: (a) a chute having sides adapted for enclosing an animal and having an entrance end and an exit end; said exit end being adapted for communicating with first and second animal segregation areas; (b) weighing means associated with said chute for determining weight of an animal enclosed in said chute; (c) a first gate being pivotally connected to said chute near one side of said chute exit end; said first gate having a first operative position wherein said first gate is generally parallel to said exit end, a second operative position wherein said first gate is at an acute angle with respect to said exit end, and a third position wherein said first gate is generally perpendicular to said exit end; (d) a second gate being pivotally connected to said chute at a location spaced outwardly from an opposite side of said chute exit end; said second gate having a first operative position generally perpendicular to said chute exit end and having a second operative position wherein said second gate is generally aligned with said first gate while said first gate is in said second operative position thereof; and (e) mechanical means for selectively moving said first and second gates through the operative positions thereof; (f) whereby when said first gate is in said first position thereof, said chute enclosed animal is prevented from egressing from said chute exit end; when said first gate is in said second position thereof and said second gate is in said second position thereof, said chute enclosed animal is free to egress from said chute into said first animal segregation area; and when said first gate is in said third position thereof and said second gate is in said first position thereof, said chute enclosed animal is free to egress from said chute into said second animal segregation area.
Claim 3
Dependent Claim
29 words
The apparatus according to claim 1 wherein: (a) said first gate and said second gate have operating means associated therewith whereby said first and second gates are remotely operable.
Claim 4
Dependent Claim
76 words
The apparatus according to claim 2 including: (a) over center locking means for each of said first and second gates whereby when said first gate is in said first operative position thereof, when said second gate is in said first operative position thereof, and when said second gate is in said second operative position thereof, then said first and second gates in each such position are respectively secured against substantial movement by an animal pushing thereagainst.
Claim 5
Dependent Claim
20 words
The apparatus according to claim 2 or 3 including: (a) an entrance gate for selectively blocking entrance to said chute.
Claim 6
Dependent Claim
43 words
The apparatus according to claim 4 wherein: (a) said entrance gate has a control mechanism associated therewith; and (b) said operating means associated with each of said first and second gates and said entrance gate control mechanism are operable from a single location.
