Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
Apparatus for illuminating a work area while simultaneously providing a safety beacon-type warning light comprising: means for holding an independently operable, normally hand-held source of illumination which provides a first directional light beam; means for diverting a portion of said first directional light beam from said source of illumination of said work area, in a second directional light beam; and, structure providing an omni-directional beacon-type warning light which utilizes the remainder of light from said first directional light beam not being diverted to said work area.
Claim 2
Dependent Claim
86 words
Apparatus for illuminating a work area while simultaneously providing a safety beacon-type warning light comprising: means for holding an independently operable, normally hand-held source of illumination which provides a first directional light beam; means for diverting a portion of said first directional light beam from said source of illumination of said work area, in a second directional light beam; and, structure providing an omni-directional beacon-type warning light which utilizes the remainder of light from said first directional light beam not being diverted to said work area.
Claim 3
Dependent Claim
17 words
The apparatus of claim 1 further including support means for holding said apparatus in an elevated position.
Claim 4
Dependent Claim
23 words

Claim 15
Dependent Claim
73 words
Attachment apparatus for use with a conventional flashlight comprising: means to connect said attachment apparatus to said flashlight; reflective means to direct a portion of a first directional beam of light from said flashlight to a work area, in a second directional beam of light; and, illuminating omni-directional beacon-type structure which utilizes that light from said first directional light beam not forming the second directional light beam being directed to said work area.
Claim 16
Dependent Claim
73 words
Attachment apparatus for use with a conventional flashlight comprising: means to connect said attachment apparatus to said flashlight; reflective means to direct a portion of a first directional beam of light from said flashlight to a work area, in a second directional beam of light; and, illuminating omni-directional beacon-type structure which utilizes that light from said first directional light beam not forming the second directional light beam being directed to said work area.
