Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
A protective shield for protecting the back of a welder''s hand from the heat and molten metal of a welding operation, comprising: flexible insulating means including a flexible, heat protective sheet for mounting with a welder''s hand; mounting means for mounting said protective sheet in a position overlapped upon itself on the back of the hand for forming an air insulation layer protecting the back of the hand from both heat and molten metal and, said protective sheet including a protective face which, in said overlapped position, is bent to form an insulating air space with said air insulation layer.
Claim 2
Dependent Claim
100 words
A protective shield for protecting the back of a welder''s hand from the heat and molten metal of a welding operation, comprising: flexible insulating means including a flexible, heat protective sheet for mounting with a welder''s hand; mounting means for mounting said protective sheet in a position overlapped upon itself on the back of the hand for forming an air insulation layer protecting the back of the hand from both heat and molten metal and, said protective sheet including a protective face which, in said overlapped position, is bent to form an insulating air space with said air insulation layer.
Claim 3
Dependent Claim
76 words
The structure set forth in claim 1, wherein said overlapping mounting means includes: a first mounting band attached to a first end of said protective sheet for mounting said first end in an overlapped position over the back of the hand palm; and, a second mounting band attached to the other end of said protective sheet for mounting said other end over the back of the fingers with said heat protective sheet in an overlapped position.
Claim 4
Dependent Claim
34 words
The structure set forth in claim 2, wherein said overlapping mounting means includes: means for flexibly mounting said protective sheet in an overlapped position for allowing greater movement of the hand during welding operations.
Claim 5
Dependent Claim
52 words
The structure set forth in claim 2, including: said protective sheet including first and second protective faces; said first mounting band being attached for extending outwardly from said first face of said protective sheet; and, said second mounting band being attached for extending outwardly from said second face of said protective sheet.
Claim 6
Dependent Claim
42 words
The structure of claim 4, further including: flexible heat resistant mounting means for mounting said mounting bands to said protective sheet to protect said mounting bands from heat and molten metal, said heat resistant means being adhesively bonded to said protective sheet.
Claim 7
Dependent Claim
73 words
The structure of claim 5, wherein said heat resistant mounting means includes: a first heat resistant mounting means and a second heat resistant mounting means being adhesively bonded to said protective sheet, said first heat resistant mounting means being bonded to said second face at said first end of said protective sheet and said second heat resistant mounting means being bonded to said first face at said other end of said protective sheet.
Claim 8
Dependent Claim
38 words
The structure of claim 5, further including: metal attaching means for securing saId mounting bands to said heat resistant mounting means to prevent separation of said mounting bands from said heat resistant mounting means when exposed to heat.
Claim 9
Dependent Claim
23 words
The structure of claim 5, wherein said heat resistant mounting means includes: leather strips for mounting said mounting bands with said protective sheet.
Claim 10
Dependent Claim
25 words
The structure set forth in claim 1, wherein: said insulating air space is formed between opposing portions of said protective face for protecting the hand.
