BROW LANTERN AND REFLECTOR SUPPORT WITH UNIVERSALLY ADJUSTABLE BASE Filed July 18, 1949 o 2 Sheets-Sheet 2 Patented July 3, 1951 NITED STATES PATENT OFFICE LANTERN AND REFLECTOR SUPPORT WITH UNIVERSALLY ADJUSTABLE BASE This invention relates to certain new and useful improvements in a lantern hood or guard and reflector.

The primary object of the invention is to provide a lantern hood or guard and reflector designed for many uses, one of which uses is herein illustrated as being in connection with a ship or boat with the hood or guard mounted on the gunwale of the boat.

A further object of the invention is to provide a lantern hood or guard of the foregoing character constructed for free rotary adjustment whereby light rays from the lamp may be directed in the desired direction, with the mounting elements for the hood or guard providing for angular adjustments in vertical directions.

A still further object of the invention is to provide a bracket mounting for the lantern hood or guard whereby the clamping elements of a bracket may be either vertically or horizontally positioned for engagement with an appropriate support.

It is a still further object of the invention to provide a lantern hood or guard in which the wall thereof that is of substantially cylindrical construction is formed of overlapping sections that may be vertically adjusted to accommodate lamps of different heights.

With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings, and claimed.

Figure 11 is a detailed sectional view taken on line ll ll of Figure 10, and

Figure 12 is a fragmentary plan view of the perforated head portion of the hood or guard.

Referring more in detail to the accompanying drawings, there is illustrated a lantern hood or guard and reflector that comprises a supporting frame designated in general by thereference character l5, a lantern hood or guard mounted thereon and generally indicated at Iii, while the lantern mounted within the hood or guard is shown at IT.

The supporting frame, as shown most clearly in Figures 2, 4, and 6, comprises a ring l8 having a section 19 thereof set in a plane below the plane of the other section 20 for purposes presently to appear. Crossed reinforcing spider arms 2i and 22 are connected at their outer ends to the ring and their crossing points form a hub 23. The spider arm 22 adjacent the ring. section 20 carries an upwardly and angularly directed arm i l for the pivotal mounting of a vise-like clamp that has a bar 25 carrying depending

end lugs

26 and 21 adapted to straddle a support 28 such as a gunwale or the like with r the leg 26 engaged'with one side of the gunwale.

Aclamping screw 29 threaded through the other leg 2'! engages the other side of the gunwale for the rigid mounting of the supporting frame. An arm 3!] extends from the end of the bar 25 for pivotal mounting as at 3| to the upper end of the: arm 24 as shown in Figures 2 and 6.

The lantern hood or guardincludes a base plate-32 of disk form and'a headed bolt tspasses centrally downwardly through the base plate 3 2 and the-hub 230i the: spider arms forthe' reand 2. through the rear side of the wall 49 of the lan- 3 ception of lock nuts 34 on the lower end thereof, washers or gaskets 35 being interposed between the base plate 32 and hub 23 whereby the disk plate is freely rotatably mounted on the supporting frame. A plate upon which the lantern i7 is fixedly mounted is indicated by the reference character 36 and is supported on the base plate 32, the bolt 33 passing centrally therethrough, while said pate 36 is anchored at suitably spaced points by screws or the like 3'! passing therethrough and entering the base plate 32 as shown in Figure 6.

A split clamping ring 38 surrounds the plate 3t and extends thereabove as illustrated for engagement with a base flange on the lantern I? and said split ring is then secured together at its split ends by lug and bolt combinations 3% as shown in Figures 1 and 3.

The hood or guard It for the lantern is secured to the base plate 32 and includes a vertically semi-cylindrical wall 3% surrounding the base plate at its lower end and anchored thereto as at Ill. An arched hood 42 is secured to the upper end of the wall t!) and has a lip extension 43 at its upper end that overlies the upper end of the cap as of the lantern l? as shown in Figure 5. A lifting handle 45 for the guard or hood has one end leg es thereof anchored to the hood 42 in proximity of the lower rear edge thereof, while the other end leg 4'? of the handle extends over the lip 53 on the hood (52 with a threaded bolt 53 passed upwardly through the lantern cap 4! lip 43, handle leg Ail for the reception of a retaining nut 4;). The reference character 553 designates a hinge-d bail secured to the lantern as shown in Figures 1 Access may be had to the latern li tern hood or guard by the provision of an opening in the lower end of the wall ll] that is normally closed by a cover 52 hinged to the wall as at 53. a

When it is desired to rotatably adjust the 'hood it that is fixed to the base plate 32, the latter may be readily grasped at its forward side which is made possible by the lowering of the section IQ of the ring of the supporting frame. It will also be observed that the upper section 20 of the ring it has an upset portion 2?? to provide a clearance for movement of the bar 25 of the bracket clamp. Also, the bar 25 of the bracket clamp carries a transversely exescape of heat rising from the lantern.

In lieu of the ring l8 and its four spider arms 2| and 22, a skeleton frame may be substituted as shown in Figure 1 wherein the central hub 23 has two arms Zi and one arm 22 radiating therefrom, the arm 22* carrying at its outer end a block enlargement 56 on which the clamp arm 36 may be pivotally mounted.

The spilt clamping ring 38, as shown in Figure 6, for anchoring the lantern I! in position may be eliminated and the plate 36 shown in Figure 8 may have radial slots 51 therein for the slidable mounting of adjustable clamps 53 that engage the base of the lantern as will be 4 understood from an inspection of said Figure 8 and also Figure 9.

The lantern hood or guard I6 is shown in Figures 1, 2, and 6 as comprising a single semicylindrical wall 4%, but in Figures 10 and 11 a modification of the hood or guard is shown and it comprises upper and lower semi-cylindrical wall sections 69* and flil that are assembled in vertically telescoping relation with interfitting beaded edges as shown in Figure 11 that are held in adjusted position by the set screws 6B associated with said beaded edges. An extensible structure of this character will accommodate a lantern of difierent heights.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that the supporting frame It forming the base structure of the hood or guard may be mounted on the gunwale of a boat as illustrated in Figures 2 and 6, or the supporting frame may be mounted on a fiat table support or the like upon laterally shifting the U-shaped vise-like clamp comprising the bar 25 and lugs 26 and 2?. Rotary adjustment of the hood or guard is facilitated by its axial rotation on the vertical pin 33 so that light rays may be cast in the desired direction.

While there are herein shown and described the preferred embodiments of the invention, it is nevertheless to be understood that minor changes may be made therein, such as will fall within the scope of the invention as claimed.
