Abstract
Abstract An article of apparel, preferably in the form of a glove with fingers, has a pocket on the back thereof, a combustible tablet within an air-permeable container is disposed within the pocket, a tubular conduit extends from the pocket, around to the palm portion of the glove, a flexible, resilient pump or bladder is disposed in said palm portion and said conduit is connected to the input portion of the bladder. The bladder has either output openings or elongated hollow output fingers for directing heated air arriving from the conduit, toward and into the fingers of the glove for heating them. The bladder is manually operated by one or more repeated squeezes of the user''s hand when said finger heat is desired.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
209 words
An article of apparel comprising at one portion thereof an enclosed source of heat which is higher than the ambient temperature, a manually operable pump means separated from said source of heat, input heat means for said pump means comprising an avenue of communication between said source of heat and said pump means, and output heat means on said pump means to direct said input heat means to a different portion of said apparel, said enclosed source of heat comprising a combustibly operated device which is enclosed in a pocket, said manually operable pump means comprising a flexible, resilient bladder connected at its input to said pocket by a conduit, and said output heat means comprising at least one opening at the output end of said bladder for directing said heat means to said different portion of said apparel, said article being a fingered glove, said pocket being disposed at the back of said glove, said combustibly operated device comprising a combustible tablet enclosed within a rigid container which is air permeable, and said pump bladder being disposed adjacent the palm of the glove whereby manual pressure of the user''s hand by squeezing the bladder will transfer the heat from said pocket to the finger portion of the glove.
Claim 2
Dependent Claim
209 words
An article of apparel comprising at one portion thereof an enclosed source of heat which is higher than the ambient temperature, a manually operable pump means separated from said source of heat, input heat means for said pump means comprising an avenue of communication between said source of heat and said pump means, and output heat means on said pump means to direct said input heat means to a different portion of said apparel, said enclosed source of heat comprising a combustibly operated device which is enclosed in a pocket, said manually operable pump means comprising a flexible, resilient bladder connected at its input to said pocket by a conduit, and said output heat means comprising at least one opening at the output end of said bladder for directing said heat means to said different portion of said apparel, said article being a fingered glove, said pocket being disposed at the back of said glove, said combustibly operated device comprising a combustible tablet enclosed within a rigid container which is air permeable, and said pump bladder being disposed adjacent the palm of the glove whereby manual pressure of the user''s hand by squeezing the bladder will transfer the heat from said pocket to the finger portion of the glove.
Claim 3
Dependent Claim
39 words
An article of apparel according to claim 1 and wherein said output heat means from said bladder further comprises a plurality of hollow tubes extending toward and entering the fingers of the glove so as to provide heat thereto.
Claim 4
Dependent Claim
40 words
An article of apparel according to claim 2 and including a one-way valve at the input end of said bladder for transferring heated air only in the direction of said hollow tubes and thence to the fingers of said glove.
Claim 5
Dependent Claim
47 words
An article of apparel according to claim 3 and wherein said hollow tubes are of thin, flexible, resilient material of a thinness so as to substantially flatten and discourage the return flow of air therethrough when squeezing pressure on said pump bladder is released by the user.
