PORTABLE EXTENSION LIGHT SHIELD WITH CLAMP Filed July 19, 1950 Patented Aug. 26, 952
uNiTEo' STATES PATENT-OFFICE If :Pon'rABL EXTENSION tron'rfsnmtn p i i wrrn CLAMP Thurman L. Day, IndianapoliaIn dr Application tin 19, 1950, Serial No. 174.603 i f This invention relates to a portable extension light "shield. i Light shields of a portable nature for use ingarages and factories are oldin the art.
of light in the fdesiredfdirectionfit is obvious that as they, swing from one'side to the other, the light is trainedfor'a while on the desired object and then alternately off of it. Second, whenever the conventional shields are placedflat on the floor or ori 'a -table they tend to roll out of position, thereby making them ineffective.
It is the primary object of the present invention to providea shield which will eliminate the foregoing difiiculties and disadvantages.
The main feature of the present invention resides inaisimply constructed, easily operated clamp construction wherein one side of the shield itself serves as one oi the clamping members.
" It is a] further object of the present invention to make possible the ready insertion and removal of the lamp bulb. Heretofore it has been the practice to provide a hinged top portion for the shield to make possible the insertion or removal of the bulb after the top has been swung back. This construction has been unsatisfactory since the top opening is generally not large enough to accommodate the hand.
An additional feature of the present invention lies in a hinged shield portion which enables one entire side of the shield to be opened and which thereby facilitates the insertion and removal of the lamp bulb.
The full nature of the invention will be understood from the accompanying drawings and the following description and claims:
In the drawings,
Fig. 1 is a side elevation view of the invention.
Fig. 2 is a top plan view thereof.
Fig. 3 is a side elevation view looking at the side thereof to which the clamping element is secured.
In the drawings, It shows the handle portion which receives and accommodates therewithin the extension cord (not shown) which cord is suitably connected to apower source (not shown) The handle is provided with a suitable socket H for receiving therewithin the light bulb l2. Disposed about the bulb is the shield which com: prises a substantially square configuration throughout most of its length with its lower portion inwardly tapered as shown at l3. More than one-half of the shield consists of wire elements [4 which are spot welded or similarly secured at the lower portion to the resilient clamping collar I5. This collaris of a size such that it may be clamped about the upper portion of the handle I0 to hold the wire cage section of the shield in the proper location. Extending across the upper portion of the wire cage section of the shield are wire elements l6 having their free ends looped or bowed at IT to-fit-over the upper extremity of the wire element 18. The rest of the shield other than the wire cage section comprises a' solid piece of metal or other suitable material [9, the inner portion of, which serves asareflectori' The top of section H! is apertured at I'Qa to accommodate the free ends of elements [5. This arrangementthus provides a hinge connection between the wire cage section and the fixed, solid section. It is "consequentl'y possible, whenever bulb insertion or removal is desired, to separate the clamping collar l5"from engagement with the upper portion of the handle. Then the Wire cage section can be pivoted to a position where bulb insertion or removal is readily accomplished.
The clamping means include the lever 20 pivotally secured at 2| to the portion IQ of the shield. The upper extremity of this lever terminates at a point which is level or coplanar with the upper end of the shield.
Mounted about the handle 10 immediately below the socket carried thereby is the split collar 22 having ears 23 formed therein. This collar has apertures formed through the ears so that the securing means 24, such as a bolt or screw may be received therethrough to hold the collar in clamping relation about the handle. On the opposite side of the collar from said ears, and interposed between the lower portion of the lever 2| and the collar is the spring 25, the innermost coil of which is suitably secured to the wall of the collar 22. This spring normally constrains the upper portion of the pivoted clamp or lever into abutting engagement with the metallic portion [9 of the shield by forcing outwardly the lever portion of the lever. When it is desired to clamp the shield in a position where it can best reflect light upon the work being accomplished, the
user presses inwardly on the bottom portion of the lever, thereby overcoming the constraint of the spring and separating the upper portion of the lever from abutting engagement with shield section IS. The pressure will, of course, be released once the shield is disposed in the desired position, whereupon the tension of the spring will once again force the upper portion of the lever into gripping engagement with the object to which the shield is connected. The object will,
of course, be disposed between the inner face of the lever and the outer face of shield section 19.
' extension light having a handle, comprising a substantially square bulb-shielding cage carried by said handle, said cage. including a solid reilector portion having three sides and a .top and an independent and complementary wire portion definingthree sides and a top, resilient clamping meansicarried by said wire portion and detachably connected to said handle, a hinge connection between the upper ends of said reflector and wire portions, and a clamping member cooperable with said cage to support it upon an object, said member comprising a single flat jaw pivotally mounted intermediate its ends to said cage, and resilient means normally constraining a portion of said member into abutting relation with said cage, said last mentioned means being interposed between said handle and a portion of said member remote from its clamping portion.
A-combined shield and holder for a portable extensio'n'light having a handle, comprising a substantially square bulb-shielding cage carried by said handle, said cage having its lower extremity inwardly tapered and including a solid reflector portion and'an independent and complementary wire portion, resilient clamping element carried by the lower extremity of said wire portion and detachably embracing said handle, a hinge connection between the upper ends of said reflector and wire portions, and a clamping member cooperable with said cage 'to support it upon an object, said member comprising a jaw pivotally mounted on said cage adjacent the junction of said tapered lower extremity with the upper portion thereof, said member being normally disposed in substantially parallel relation to the longitudinal axis of said cage, and resilient means normally constraining the portion of said member above the pivotal mounting into abutting engagement with said cage, said last mentioned means being interposed between said handle and a portion of said member below said pivotal mounting. f 3. A combined shield and holder for a portable extension light having a, handle, comprising a bulbrshielding cage carried by said handle, said cage having its lower extremity inwardly tapered and including a solid light reflector portion having three sides and a top and an independent and complementary wire portion defining three sides and a top, a resilient clamping element of split ring type carried by the lower extremity of said wire portion and detachably connected to said handle, a hinge connection between the upper ends of said reflector and wire portions respectively, and a clamping member cooperable with said cage to support it upon an object, said member comprising an elongated straight fiat jaw pivotally connectedintermediate its ends to said cage adjacent its tapered extremity, the portion of said jaw disposed above the pivotal connection normally lying in abutting relation with the upper portion of said cage, the portion of said jaw disposed below said pivot normally lying in spaced relation to the tapered extremity of said cage and to said handle, and a coil springinterposed between said handle and a portion of said jaw disposed below said pivotal connection, said spring normally biasing the portion of said jaw above the pivotal connection into abutting relation with the upper portion of said cage.
