Abstract
Abstract In a combination of a tool holder and a flashlight, the flashlight proper illuminates the area in which work is being performed by the particular tool inserted into the tool holder. Various tools may be inserted into the tool holder. To simplify operation of such a composite device the casing of the flashlight is adapted to perform two functions, i.e. to receive the dry cells for operating the flashlight, and to store additional tools which may be inserted selectively into the tool holder.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
220 words
A combined tool holder and flashlight including a substantially tubular housing for dry cell means closed on one of the end surfaces thereof by a lens arranged in front of an incandescent lamp and supporting a chuck for selectively securing various tools to said lens wherein a. said housing is provided with an internal partition subdividing said housing into a dry-cell-receiving chamber and a tool-receiving chamber, the outer wall of said housing and said internal partition being interconnected by a plurality of radially extending integral webs subdividing said toolreceiving chamber into a plurality of separate compartments and one of said plurality of webs defining a groove-shaped recess open at the side thereof adjacent said dry-cell-receiving chamber and accommodating a current conductor having a lower bent resilient end projecting out of said groove-shaped recess into said dry-cell-receiving chamber; b. said dry-cell-receiving chamber is open at the end thereof adjacent said incandescent lamp and closed by a bottom portion at the end thereof remote from said incandescent lamp; c. the ends of said plurality of separate compartments remote from said incandescent lamp are open and situated within said housing; and wherein d. the end of said housing remote from said incandescent lamp is provided with a cover means for retaining within said housing tools placed in any of said plurality of compartments.
Claim 2
Dependent Claim
220 words
A combined tool holder and flashlight including a substantially tubular housing for dry cell means closed on one of the end surfaces thereof by a lens arranged in front of an incandescent lamp and supporting a chuck for selectively securing various tools to said lens wherein a. said housing is provided with an internal partition subdividing said housing into a dry-cell-receiving chamber and a tool-receiving chamber, the outer wall of said housing and said internal partition being interconnected by a plurality of radially extending integral webs subdividing said toolreceiving chamber into a plurality of separate compartments and one of said plurality of webs defining a groove-shaped recess open at the side thereof adjacent said dry-cell-receiving chamber and accommodating a current conductor having a lower bent resilient end projecting out of said groove-shaped recess into said dry-cell-receiving chamber; b. said dry-cell-receiving chamber is open at the end thereof adjacent said incandescent lamp and closed by a bottom portion at the end thereof remote from said incandescent lamp; c. the ends of said plurality of separate compartments remote from said incandescent lamp are open and situated within said housing; and wherein d. the end of said housing remote from said incandescent lamp is provided with a cover means for retaining within said housing tools placed in any of said plurality of compartments.
Claim 3
Dependent Claim
126 words
A combined tool holder and flashlight including a substantially tubular housing for dry cell means closed at one end surface thereof by a lens arranged in front of an incandescent lamp and supporting a chuck for selectively securing various tools to said lens, wherein the outer wall of said housing and an internal coaxial partition thereof forming a dry-cell-receiving chamber are interconnected by a plurality of radially extending integral webs, said plurality of webs defining a plurality of tool-receiving chambers separate from each other, and one pair of said plurality of webs defining a groove-shaped recess open on the side thereof adjacent said dry-cell-receiving chamber and accommodating a current conductor having a lower bent resilient end projecting out of said groove-shaped recess into said dry-cell-receiving chamber.
Claim 4
Dependent Claim
126 words
A combined tool holder and flashlight including a substantially tubular housing for dry cell means closed at one end surface thereof by a lens arranged in front of an incandescent lamp and supporting a chuck for selectively securing various tools to said lens, wherein the outer wall of said housing and an internal coaxial partition thereof forming a dry-cell-receiving chamber are interconnected by a plurality of radially extending integral webs, said plurality of webs defining a plurality of tool-receiving chambers separate from each other, and one pair of said plurality of webs defining a groove-shaped recess open on the side thereof adjacent said dry-cell-receiving chamber and accommodating a current conductor having a lower bent resilient end projecting out of said groove-shaped recess into said dry-cell-receiving chamber.
Claim 5
Dependent Claim
139 words
A combined tool holder and flashlight including a substantially tubular housing for dry cell means closed at one end surface thereof by a lens arranged in front of an incandescent lamp and supporting a chuck for selectively securing various tools to said lens wherein said housing is provided with a partition subdividing said housing into a noncoaxial dry-cell-receiving chamber and into a tool-receiving chamber substantially sickle-shaped in cross section having a relatively small width adjacent one end thereof and a relatively large width adjacent the opposite end thereof, and wherein the common axis of said lens and said incandescent lamp are spaced from the axis of said dry-dell-receiving chamber and wherein said incandescent lamp has screw socket means extending sufficiently far radially outwardly to establish contact with the center terminal of a dry cell arranged in said dry-cell-receiving chamber.
Claim 6
Dependent Claim
139 words
A combined tool holder and flashlight including a substantially tubular housing for dry cell means closed at one end surface thereof by a lens arranged in front of an incandescent lamp and supporting a chuck for selectively securing various tools to said lens wherein said housing is provided with a partition subdividing said housing into a noncoaxial dry-cell-receiving chamber and into a tool-receiving chamber substantially sickle-shaped in cross section having a relatively small width adjacent one end thereof and a relatively large width adjacent the opposite end thereof, and wherein the common axis of said lens and said incandescent lamp are spaced from the axis of said dry-dell-receiving chamber and wherein said incandescent lamp has screw socket means extending sufficiently far radially outwardly to establish contact with the center terminal of a dry cell arranged in said dry-cell-receiving chamber.
Claim 7
Dependent Claim
102 words
A combined tool holder and flashlight as specified in claim 3 wherein said incandescent lamp is surrounded by a concave reflector having a tubular extension at the apex region thereof, a metal sleeve being mounted on said extension and having a lamp-receiving screw shell forming an integral part thereof, an insulating sleeve having a flange being mounted on said metal sleeve, a metal cap being crimped around said flange and a flexible tab being formed by said cap, said tab extending substantially radially outwardly from said common axis of said lens and said incandescent lamp toward the axis of said dry-cell-receiving chamber.
