Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
316 words
Animal warming apparatus comprising an elongated sheet metal hood having a triangular cross-section formed by a pair of side walls joined along a common edge to form an apex line with their opposite edges spaced apart to form a chamber between said walls, said opposite edges of said walls being bent inwardly to form a horizontal ledge extending along the length of each of said walls, said hood being free of holes and projections which might act as dust and dirt catchers, at least two hook members secured to said apex line of said hood whereby said hood can be secured to a support member and whereby said hood can be tilted about its longitudinal axis by means of auxiliary hooks secured to the free edge of one of said walls to permit the apparatus to be aimed at a desired location, metal end walls secured to the opposite free ends of said walls to close the ends of said hood, two auxiliary support walls secured to said side walls inside said chamber, each being spaced from one of said end walls to provide two small chambers in which electrical wiring elements can be disposed, an elongated electric heating element disposed inside said chamber and supported by said auxiliary support walls, a curved reflector element disposed inside said chamber surrounding said heating element and having its edges supported on said ledges formed at the free edges of said side walls, at least one wire-like auxiliary support member supporting said heating element and itself being supported on said ledges, and a thermal electric sensor electrically connected to said heating element and an insulated electrical cable, said thermal sensor being secured at the end of said cable, said cable is coupled to said hood and being adjustable to vertically position said thermal sensor at a desired distance directly beneath said hood to sense heat directly beneath said hood.

Claim 3
Dependent Claim
17 words
The apparatus defined in claim 1 and including an auxiliary reflector element disposed beneath said heating element.
Claim 4
Dependent Claim
52 words
The apparatus defined in claim 1 and including an auxiliary reflector element disposed beneath said heating element extending along the length of said heating element and having a generally triangular cross-section so that radiant energy from said heating element is diffused laterally thereby to cover a relatively wide area beneath said apparatus.
Claim 5
Dependent Claim
27 words
The apparatus defined in claim 1 wherein said thermal sensor is of such adjustability that it can be positioned beneath said apparatus among the animals being warmed.
Claim 6
Dependent Claim
30 words
The apparatus defined in claim 1 wherein said thermal sensor is secured to a support surface adjacent to said apparatus and is enclosed and protected by a protective screen member.
Claim 7
Dependent Claim
89 words
The apparatus defined in claim 1 and including a pair of rods, each secured to one of said end walls and extending vertically downwardly a short distance from said walls whereby, if the support means which is secured between the ceiling of a building and said hook members breaks and said apparatus falls, then the apparatus lands on said rods and said rods cause said apparatus to rotate and not fall vertically downwardly whereby said heating element is prevented from burning anything which might be located directly beneath it.
