Abstract
Abstract A therapeutic legging for bovine, equine or like animals, comprising an electrically heated sleevelike covering contoured to fit the leg of an animal. The sleevelike covering may be battery operated or it may be plugged into a standard alternating current outlet. An adjustable control regulates the amount of electrical energy delivered to the heating element for the covering, and means are provided for preventing excessive heating to protect the animal and also the materials of the covering.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
277 words
A therapeutic legging for treating a leg of a bovine, equine or like animal, comprising a covering in the form of a contoured sleeve adapted to fit around the leg of the animal, said sleeve being formed of a flexible, heat insulating material which is longitudinally split so as to be readily applied to and removed from the leg of the animal, releasable fastening means for securing the longitudinal edges of said sleeve together along said split, releasable fastening means at one end of said sleeve for retaining said sleeve on the leg of the animal, heating means comprising an elongated electric heating element secured to said sleeve and extending throughout a major portion of the length and width thereof, an electric control unit for said heating element, a pocket on said sleeve for removably receiving said control unit, said control unit including an electric control circuit adapted to be connected to said heating element, said electric circuit including a silicon controlled rectifier adapted to pass current upon being triggered, said electric control circuit also having a trigger circuit for periodically triggering said rectifier, said trigger circuit including a capacitor, an electronic switch for discharging said capacitor to transmit a triggering signal to said rectifier, a potentiometer for controlling said electronic switch, an automatic temperature sensitive resistor for preventing overheating of said sleeve, a battery unit including a battery and a variable resistance control therefor, said heating element having means for selectively plugging into said electric control unIt or said battery unit, said sleeve having an inner layer of non-absorbing material such that liniments used to treat the leg of the animal will not penetrate said sleeve.
