F2lv l/08 [58] Field of Search 240/44.l, 11, 27, 29, 24, lg i 'x s z g i fe f gl gglli l l l e lall tggag 240/38, 39, 465.3, 108 BA, 110, 15, 52.15, width 1 Claim, 5 Drawing Figures LANTERN SHIELDS This invention relates to lanterns, more particularly to devices attachable to a lantern for modifying the light beam.

A principal object of this invention is to provide a type of shield which, in a pair, attached pivotally at the top of the lantern allows turning the shields with respect to each other.

Another object of the present invention is to provide shielding of the type described that is cheap in construction and material and therefore widely marketable.

Yet another object is to provide a shield for the intended purposes, and which is attachable by magnet means.

These and other objects will become readily evident upon a study of the following specification together with the accompanying drawing wherein:

FIG. 1 is an elevation view of one shield installed on a lantern;

FIG. 2 is a plan view thereof;

FIG. 3 is a plan view of a modified form of shield in a pair in one operative position;

FIG. 4 is a plan view of a pair of shields of the style shown in FIGS. 1 and 2 applied to a lantern in another operative position;

FIG. 5 is a fragmentary elevation section view of a modified design of the invention.

Referring to FIGS. 1 and 2, a shield 10, according to the invention, comprises a light shielding member 11 extending upward and bent over it an arm 12 and hav ing two or moreopenings 13 for attachment to the top of a lantern 14 by means of a screw and winged nut 15.

The width of the shield determines the amount of remaining area to 'which light rays 16 can radiate, as shown in FIG. 2.

Referring to FIG. 3, a pair of shields 17 are shown positioned in contact whereby giving a spread of light indicated by a pair of rays 18. It becomes evident from this figure that separation of shield 17 immediately yields two beams of light, the center line of which are diametrically opposed.

When a pair of shields are positioned oppositely as shown in FIG. 4, two equal beams of light are provided as indicated by pairs of

rays

19 and 20.

A study of the figures and the foregoing description will show the advantages of this type of sheild. Illumination may be thrown in a desired direction, in a desired with of beam or in a desired, oppositely-directed pair of light beams. The invention is particularly desirable to night fishermen who want to have light on both sides of the boat yet wish to have the light kept out of their eyes. In the camp or for shore fishing, the shields lend themselves to a variety of applications for directing light in one or two directions.

Reference is now made to FIG. 5 of the drawing wherein there is shown a magnet assembly 21, and which is comprised of a threaded rod 22 that is attached or welded to a plate 23 to which a magnet 24 is cemented.

In a further modified design of the invention, not illustrated in the drawing, the shields may be supported by magnets on the under side of the shields that comprise a sole support or used additionally to the above described support means.

In a further modified design of the invention, not illustrated in the drawing, the shields cannot be attached and still be adjustable, while fitting a lantern without a center rod, by means of having magnets on the underside of the shields, either additionally or separately.

Thus different forms of the invention are indicated.

What I now claim is:

1. A lantern assembly, comprising in combination, a lantern and a shield unit, said shield unit comprising a pair of shield members adjustably supported upon said lantern, each one of said shield members having a flat side which at its upper edge or end is integral with a horizontally extending tab, said side being vertically positioned adjacent a side of said lantern, said horizontal tab extending in a radially direction on top of said lantern and secured there to, said tab having a pair of openings there through in spaced apart relation for selectively receiving an upward extending screw integral with said lantern, said shield member being pivotable respective to each other upon said screw and secured in selected adjusted position by means of a wing nut fitted upon said screw, said side of said shield additionally supporting a threaded rod there through fitted with a washer adjacent each side of said shield member vertical side, a nut adjacent each outer side of said washers thus allowing axial adjustment of said threaded rod respective to said shield member side, one end of said threaded rod being integral with an enlarged plate on which a magnet is secured, said magnet being adaptable to engage any ferrous part of said lantern.
