LNT-ERN FOR ELECTRIC LIGHTlNG.
SPECIFICATION forming part of Letters Patent No. 484,449, dated October 18, 1892. Application led December 12,'1891. Serial No. 414,783. (No model.)
l To all whom t may con/cern.-
Be it known that we, DANIEL S. PAGE, re-
siding at Malden, and JOSEPH L. Bumsen,
A ers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to'iigures of reference marked thereon, which form a part of this specification.
This invention relates to lanterns, especially such as are adapted to contain electric lights and employed in marine service.
The obj ect of our invention is to enable the lantern to be used for two dierent purposes and adapt it to perform such duties as usually require theqservices of two lanterns of distinct construction.
Briefly described, our invention consists in' an ordinary lantern which is equipped with a removable shield. To the latter is attached an adjustable slide. Thus by taking oft the shield an ordinary open or deck lantern is produced, while it the shield is affixed in positionan act very readily done-a battlelantern or deck-lantern with shield is created. By means of the latter construction should the slide be drawn out the light is effectually concealed, or by withdrawing said slide it may be exposed Wholly or in part, while the rays may be emitted in any direction desired by turning the lautern'so as to bring the uncovered part of the lantern-globe in that direction.
The drawings accompanying this specification represent,in Figure 1,a lantern embodying our invention in elevation, shown as an ordinary open or deck lantern. Fig. 2 represents the same equipped with the shield and slide to be used as a battle-lantern or decklantern with shield. Fig. 3 is a perspective view of the shield and slide.
In said drawings the lautern is shown as consisting of the usual ornamental cap 2, beneath which is secured the lantern head proper 3, with a flange at 4. To this ilange is attached the wires or rods 5, which serve to protect the lantern-globe. The latter is of a cylindrical form, closed at the bottom and open at the top. The upper extremity is exteriorly screw-threaded to engage the screwthreads formed interiorly Aon the lanternhead, while a gasket 7, of rubber or analogous material, is held between said globe and the lantern-head to make the interior space of said globe steam and water tight, and thereby insure the safety of the electric-light bulb. The latteratSis for use on an incandescent electriclight system and is removably attached to and pendent from a central tube 9, adapted to receive the conducting-wires l0. These latter are properly insulated and covered with packing or other material which shall completely fill the bore of said tube and likewise prevent the entrance of steam or water within the lantern-globe at this point. A metallic basering 12 of any ornamental cross-section receives the lower ends of the rods or guardwires, thereby making the structure strong and rigid. A handle or bail 13, by which to carry the lantern or from which to support it in any suitable spot, surmounts the cap.
To render this lantern serviceable, either as an open-deck lantern (see Fig. 1) or a battle-lantern or deck-lantern with shield, as in Fig. 2, we have removably attached a pendent apertured shield 14., by means of atlange 15 to the lantern-head. This flange or lip is formed with suitable holes 16 (see Fig. 3) of suicient size to admit the heads of the holding-screws 17, which engage in the iiange of the lantern-head, while a slot 18 extends from each of said holes. These slots are of a size to receive the body of the screw. Hence in order to attach the shield to the lantern the holes are caused to register with the screws, the flange 15 is thrust over them, and a slight turn given to said shield, which causes the body of the screws to enter the slots 18. The
screws are then turned home and the shield is secured in place and forms a fixed part of the lantern, being located between the lantern-globe and the outside protector-rods.
The above arrangement obviates the removal of the screws from the iiange of the IOO lantern-head and enables the shield `to be put on or taken off very quickly and easily. Inclosing the body of the shield is loosely fitted an adjustable slide 19,1vhich is held in place by the flange l5 of said shield at the top and a bead or projection 2O at the bottom. A hand-grasp 2l serves to mov-e it circumferentially about .the shield. Both the shield and its slide are sections of cylinders with co-operating openings, respectively, semicylindrical in shape, or approximately so, in order that the two parts `whenusedconjointlyshall create an impertorate or closed cylinder, the edges of the slide `overlapping in part the edges of the shield (see Fig. 3) to eiiectually' prevent the passage of light at .the time the` slide is drawn forward into an active position.
'In -theoperation vof tllisapparatnsasabattle-lantern or deck-lantern withshield when :the slide is drawn over the aperture which' exist-s `=in the shield ythe light is etfectually, -concealed. On the othei` hand, if the slide is p drawn entirely .back the full .power of the light -isfexposed,and the rays ,arethen emit- 4ted .through an arc, wliiclrmayfbe ot one hun-- =dned.and.eighty degrees, but-the extent 'of' which isdetermined by the sizeof ,the aper-l turein .theshield as controlled `by Athe slide.l
The n'shapevof the.shield-.aperture may be ot The rays will be cut `:ol`t` Ybysthetshieldfin the :rearof the light,as.in aA Vsearch-light, at alltimesvvhen such shield is V1n any form desired.
ythelightpineandescent or otherwise, may be vemployedto emitrays in .every `direction or,` for ahorizon of .three ,hundred and sixty .de- ,grees In theevent-of theaddition of thel shield and slide said rays are limited from a horizon of a semicircle or..one hundred and eighty degrees at such time as the slide is fully open to a horizon of no degrees, or when the slide is completely closed.
What We claim is- `l. As a new article .of manufacture, a lantern composed of alantern-head, a lanternglobe, protector-rods to surronn'd the latter, and a removable apertured shield with an adjustable slide to inclose said lantern-globe, substantially as herein set forth.
2. The combination, with a lantern, of a shield composed of an imperforate cylindrical apertnred plate, and means whereby said shield may bedetachably held in place upon the lantern,and an adjustable slide movable about said shield and adapted -to close said aperture in the shield, substantially as explained.
3. In combination ,with ,a ilanged lanternhead, the globe removably attached thereto, the `packing tofform a `tight joint, andqtheexterior l{,guard-.roda a removable apertured shield secured to said 1an t,ern,head ,a slide `adjustable .about lSaid shieldand a hollow `tube to admit electric conduc,tors,.,as 4herein .set :forth and speciiied.
4. The combinatiomwitlia,capped lantern- .head, its `exteriorguardfwires,.and annular base-ring,yot` a lanternfglobe adapted .to form a steam and Water ,tight joint withsaid head,
