Abstract
Abstract An improved electric cow trainer having a plurality of training members, each associated with a separate animal stall, is described. The design of the present invention permits all of the training members to be simultaneously rotated between their operating position just above the backs of the cows when they are standing in the stall to a second, elevated position well above the heads of people working in the barn. In this second position, the training members are neither a nuisance or dangerous to those working in the barn.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
123 words
A cow trainer for use in a barn having stalls comprised of: (a) a plurality of electrically conductive training members; (b) an electrically conductive support shaft; (c) first locking means for securing said electrically conductive training members to said shaft in any one of a plurality of pre-selected angular orientations; (d) means for supporting said shaft above said stalls; (e) means for electrically insulating said support means from said shaft; (f) means for simultaneously rotating said shaft and the electrically conductive training members locked to it between a plurality of pre-selected positions; (g) second locking means for maintaining said shaft and electrically conductive training members in a desired pre-selected position; and (h) means for energizing said shaft and said electrically conductive training members.
Claim 2
Dependent Claim
123 words
A cow trainer for use in a barn having stalls comprised of: (a) a plurality of electrically conductive training members; (b) an electrically conductive support shaft; (c) first locking means for securing said electrically conductive training members to said shaft in any one of a plurality of pre-selected angular orientations; (d) means for supporting said shaft above said stalls; (e) means for electrically insulating said support means from said shaft; (f) means for simultaneously rotating said shaft and the electrically conductive training members locked to it between a plurality of pre-selected positions; (g) second locking means for maintaining said shaft and electrically conductive training members in a desired pre-selected position; and (h) means for energizing said shaft and said electrically conductive training members.
Claim 3
Dependent Claim
21 words
