Abstract
Abstract A cold-weather muff includes an elongated generally cylindrically shaped insulative member having open ends, a water resistant and wind-proof lining surrounding the insulative member, and an inner liner disposed within the insulative member having longitudinally opposed left and right hand receiving pockets and a chemical heating element receiving chamber intermediate the left and right hand receiving pockets. Resilient collars are provided on the open ends that are individually cooperative with respective ones of the left and right hand receiving pockets to minimize convective heat loss by preventing wind from passing through the muff. An emblem may be fastened to the outer lining displaying any desired indicia. A flap on the outer lining provides a resealable closure for the chemical heating element receiving chamber. The cold-weather muff is particularly advantageous for spectator sports, and may readily be incorporated in any suitable body garment such as a hooded sweatshirt.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
136 words
A cold-weather muff, comprising: first means defining a generally cylindrical insulative tube having a longitudinally extending channel and opened ends; second means disposed in said longitudinally extending channel for providing a left hand receiving pocket having an open end in communication with one of said opened ends of said insulative tube and having a sealed end terminating inside said longitudinally extending channel; third means disposed in said longitudinally extending channel for providing a right hand receiving pocket having an open end in communication with the other one of said opened ends of said insulative tube and having a sealed end terminating inside said longitudinally extending channel; and fourth means disposed in said longitudinally extending channel for providing a chamber intermediate said left hand receiving and right hand receiving pockets dimensioned to accept a chemical heating element.
Claim 2
Dependent Claim
136 words
A cold-weather muff, comprising: first means defining a generally cylindrical insulative tube having a longitudinally extending channel and opened ends; second means disposed in said longitudinally extending channel for providing a left hand receiving pocket having an open end in communication with one of said opened ends of said insulative tube and having a sealed end terminating inside said longitudinally extending channel; third means disposed in said longitudinally extending channel for providing a right hand receiving pocket having an open end in communication with the other one of said opened ends of said insulative tube and having a sealed end terminating inside said longitudinally extending channel; and fourth means disposed in said longitudinally extending channel for providing a chamber intermediate said left hand receiving and right hand receiving pockets dimensioned to accept a chemical heating element.
Claim 3
Dependent Claim
21 words
The invention of claim 1, further including first and second resilient collars fastened to respective opened ends of said insulative tube.
Claim 4
Dependent Claim
14 words
The invention of claim 1, further including an outer lining surrounding said insulative tube.
Claim 5
Dependent Claim
15 words
The invention of claim 3, wherein said outer lining includes a wind-proof and water-resistant fabric.
Claim 6
Dependent Claim
14 words
The invention of claim 4, further including an emblem affixed to said outer lining.
Claim 7
Dependent Claim
65 words
The invention of claim 3 wherein said chemical heating element receiving chamber has an opening through the generally cylindrical insulative tube, and further including a flap fastened to said outer lining adjacent to the opening of said chemical heating element receiving chamber that is pivotal between an open position allowing access to said chamber and a closed position that seals the opening of said chamber.
Claim 8
Dependent Claim
120 words
A cold-weather muff, comprising: an insulative tube having opened ends; a water-resistant and wind-proof outer lining surrounding said insulative tube; a liner slidably received in said insulative tube having a longitudinally extending first pocket in communication with one of said opened ends, an opposing longitudinally extending second pocket in communication with the other of said opened ends, and a chamber intermediate said first and second pockets that is dimensioned to slidably accept a chemical heating element and having an opening through said insulative tube at a point intermediate its ends; and a flap mounted to said outer lining and pivotal between an open position allowing access to said chamber and a closed position for sealing the opening of the chamber.
Claim 9
Dependent Claim
120 words
A cold-weather muff, comprising: an insulative tube having opened ends; a water-resistant and wind-proof outer lining surrounding said insulative tube; a liner slidably received in said insulative tube having a longitudinally extending first pocket in communication with one of said opened ends, an opposing longitudinally extending second pocket in communication with the other of said opened ends, and a chamber intermediate said first and second pockets that is dimensioned to slidably accept a chemical heating element and having an opening through said insulative tube at a point intermediate its ends; and a flap mounted to said outer lining and pivotal between an open position allowing access to said chamber and a closed position for sealing the opening of the chamber.
Claim 10
Dependent Claim
21 words
The invention of claim 7, further including first and second resilient collars fastened to corresponding opened ends of said insulative tube.
Claim 11
Dependent Claim
14 words
The invention of claim 8, further including an emblem fastened to said outer lining.
Claim 12
Dependent Claim
127 words
The invention of claim 7, wherein said liner is fabricated according to the following steps: folding a length of fabric to bring its ends in alignment; fastening the aligned ends together; identifying the horizontal and vertical center lines of the folded fabric; fastening the fabric together along spaced lines symmetrically disposed about the horizontal center line and extending from the vertical center line to the fastened and aligned ends; fastening the fabric together along a vertical line defined between the spaced lines in a direction parallel to the vertical center line of the folded fabric to form said chemical element receiving chamber; turning the folded and fastened fabric inside out; and selectively fastening the open ends to define said left hand receiving and right hand receiving pockets.
Claim 13
Dependent Claim
13 words
The invention of claim 10, wherein said fastening steps are accomplished by stitching.
Claim 14
Dependent Claim
75 words
A cold-weather muff, comprising: an insulative tube having spaced opened ends; an outer lining of a wind-proof and water-resistant material slidably mounted over said insulative tube; means disposed in the inside of said insulative tube for providing longitudinally opposing left and right hand receiving pockets each having an open end in communication with a corresponding one of said opened ends of said insulative tube; and first and second resilient collars fastened to respective opened ends.
Claim 15
Dependent Claim
75 words
A cold-weather muff, comprising: an insulative tube having spaced opened ends; an outer lining of a wind-proof and water-resistant material slidably mounted over said insulative tube; means disposed in the inside of said insulative tube for providing longitudinally opposing left and right hand receiving pockets each having an open end in communication with a corresponding one of said opened ends of said insulative tube; and first and second resilient collars fastened to respective opened ends.
