Wissinger, Springfield, Ohio, assignor to The Sportmans Products Company, Springfield, 01110, a partnership Application November 3, 1949, Serial No. 125,211
4 Claims. (Cl. 240-105) This invention relates to a shield for a sportsmans lantern and more particularly to the combination of a novel translucent shield with a gasoline burning sportsmans lantern.
Sportsmens lanterns are usually gasoline lamps of one or more burners having a clear glass globe. These lanterns throw an intense light which is excellent for camping, fishing and hunting purposes. The lanterns have the disadvantage of throwing a glare and causmg eye fatigue to any one who must face the light for any protracted period of time. Also, the lantern because of its intense light attracts flying insects.
In order to overcome these difficulties, the lanterns have been equipped with solid shields, especially those w1th reflector surfaces which concentrate and direct the light beams in a forward direction. The difficulty here experienced has been that in back of the shield there is created almost total darkness.
It is an object of the present invention to overcome the disadvantages and difliculties of the apparatus heretofore utilized.
It is another object of the present invention to provide means whereby glaring, intense light is eliminated from one side of the lantern without causinga blackout in the shielded zone.
It is a further object of this invention to provide means whereby the intensity of light on the intercepted light side of the lantern is subject to control.
It is a principal object of this invention to provide a novel translucent amber-colored shield for combination with a sportsmans gasoline-burning lantern which combination is effective to provide on one side of the lantern an insect-repellant zone.
It is still another object of this invention to provide a simple support whereon a shield may be supported in position adjustable both vertically and horizontally.
It is a still further object of the present invention to provide means which will not interfere with the use of the lantern for any of its intended uses in camp, on boats, or for hunting and fishing.
It is another object of this invention to provide means whereby the supporting frame for the shield may be quickly attached to or detached from the lantern without displacing any of the parts thereof.
It is a further object of this invention to provide means whereby the shield and supporting frame never contact heating zones which will. raise the temperature of the shield or support to a point making them hot enough to cause burns when it is necessary to manipulate the shield apparatus.
These and other allied objectives are attained by employing in conjunction with a sportsmans gasoline-burning lantern an amber-colored shield of plastic, which shield may partially surround the globe of the lantern and through which light from the intense light source of the lantern passes. The preferred shield is made of a synthetic resin such as methyl methacrylate for example. Such plastic is available in flat sheet form and is heattreatable to permit the flat sheet to be formed into a segment of a circle.
The amber light in the Zone behind the shield provides an area in which work may be accomplished, and insects will not be attracted to the area. The intensity of the light in the amber area is adjusted by moving the shield relative to the lantern-thus to reduce the intensity of "ice light transmitted through the shield the shield is moved outwardly from the source.
The amber-colored shield is translucent and the zone of amber light provided thereby is adapted as a workmg area as noted.
Further objects and advantages will become apparent from the following description taken in connection with the drawings in which:
Figure 1 is a perspective view of one embodiment of the invention;
Figure 2 is a view taken on line 2-2 of Figure 1;
Figure 3 is a top plan view of a shield holder;
Figure 4 is a view along the line 44 of Figure 3;
Figure 5 is a side elevational view of a lamp having mounted thereon a second embodiment of the invention;
Figure 6 is a plan view of the translucent shield of Figure 5; and
Figure 7 is a perspective view of the bracket of Figure 5.
As shown in the drawings, my invention comprises a translucent wall positionable relative to the source of light and supported in that position from a releasably attached bracket member.
In Figure 1, this invention is shown to comprise a bracket 10 adapted with a circular portion 11 to circumscribe the neck situated between the base and globe sections of a sportsmans lantern.
Bracket 10 consists of the circular portion 11 and the parallel ears 12 and 13 which are of unequal lengths. Ears 12 and 13 are brought together in clamping position by suitable means such as bolt 14.
Ear 13 is provided with a threaded extension 15. Extension 15 is adapted to receive a nipple 16 which is positioned and held rigidly fixed by locking means such as nuts 17 and 18.
Nipple 16 is provided with a projection or arm 19 which forms the base for the vertically extending portion of the support; Arm 19 is slotted at 20 (Figure 2) so as toform fingers 21 and 22, respectively.
Fingers 21 and 22 are provided with channels 23 and 24 which cooperate to receive a vertically extending post 25'. Post 25 is rigidly positioned when fingers 21 and 22 are pulled toward one another by a wing screw 26 threadedly received in aligned threaded apertures 27 running transverse to the slot 20.
Post 25 supports a pair of holders 28 and 29 shown in detail in Figures 3 and 4, corresponding parts of which will be indicated by like reference numerals. A holder 29, for example, consists of a U-shaped member 30 having legs 31 and 32 of unequal lengths.
Leg 32 at its free end is divided into three portions 33, 34 and 35 which are turned parallel to the bend. Leg portion 34 extends a greater distance from said bend, thus providing space between the leg portion 34 and compamon leg portions 33 and 35 to form a seat for and to receive a translucent shield 36.
U-shaped member 30 is slotted as at 41 forming fingers 42 and 43. Fingers 42 and 43 are provided with channels 44 and 45 which cooperate to receive post 25. Member 30 may be fixed in any desired position on post 25 by pulling the fingers 42 and 43 toward one another by suitable tension means 46 such as a bolt.
Translucent shield 36 is preferably made of an amber colored (yellowish to brownish) sheet of synthetic resin plastic, such as methyl methacrylate, phenol formaldehyde, phthalic acid base condensation products, and the like, sold under such trade names as Lucite, Plexiglas, and so forth.
The plastic which is sold as flat sheets is heat treated to form a segment of a cylinder of suitable diameter. Such shields may, of course, be molded in individual molds rather than mold large flat sheets which are cut to size and then heat treated.
This shield when it is desirable to pass as much light as possible is brought by lateral adjustment of nipple 16 into close proximity to the lamp globe. A
To reduce the light transmitted, the shield is moved outwardly until at the further most point of adjustment the shield shows as an amber face with the passage of a minimum of light. The adjustment is of major importance in adapting the lamp for many uses. For example, in camp the amber light may be directed to a work area without attracting insects to the area, whereas, in night fishing the non-transmitting position may be adapted, which will allow t'he lantern to be set at the stream edge, lighting up the bank of the stream without lighting up the stream and disclosing thevfisherman .to 170th fish and flying insects.
In Figures 5, 6 and .7 there is disclosed an embodiment of the invention involving fewer parts. This unit .is shown to consist of a unitary bracket 50 which has a circular portion 51 and two cars 52 and 53.
Bars '52 and '53 are adapted with aligned bores '54 adapted to receive clamping means such as a bolt with 'wing'nut as shown at 55. Ear '53 is turned as at '56 to a position transverse to the base and generally parallel to the center axis of the lamp globe.
Ear 53 is provided with a slot 57. Slot 57 is adapted to receive "a suitable connector '58 such as a wing nutted bolt. Bolt 58 passes through an aperture '59 in a segmental shield 60.
While the shield is shown drawn tight to the vertical portion of the ear 53, it will at once be recognized that by the use of two locking nuts mounted on bolt 58, the position of the shield may be laterally adjusted at will. Vertical movement is provided for by slot '57. Accordingly, vertical and lateral adjustments are provided for in this embodiment as well as that shown in Figures 1 to 4.
While the "method and apparatus disclosed and described herein illustrate a preferred form of invention, yet it will be understood that modifications can be made without departing from the spirit of the invention and that modifications that all within the scope of the appended claims are intended to be included herein.
