with the usual spring catch 02 for holding l the front frame closed. This frame is pro; i vided with an internal forwardly-Ilaring rel Hector forming with the surrounding' l frame a hollow annular structure. rlhis re- Hector is removably arranged in the frame, whereby the plating of the reflector is sim-v plified. The frame and the reflector are preferably provided near the glass with upper and lower pert'orations o* C5, respectively, to. permit of a circulation of air on. the inner side ot' the glass and prevent sweating of the same. The glass is secured to the rim of the frame by any suitable fastening, for instance, by a divided ring'ci and clamp-screw ci, Figs. 1, 2 and 7.
The back plate D is preferably made conf cave on its :trentl side and hinged at one side to the bodylA, as shown at d, and secured at the other side by a spring catch (Z1 or otherwise movably attached. This plate carries on its front side a concave reflector E, which may be secured to the baci: plate in various ways. Aln the construction represented in Figs. 3, 6 and 10 the back plate is provided with diverging spring arms e, which yieldingly grasp the rim of the reflector, wh ile in the construction represented in Figs. 14 and 15 the back plate is provided at its lower trent side with a socket el for the reception ot' a tang or arm @2, secured to the-rear side ol' the reflector, and the upper portion of the reflector is engaged by a spring arm ei" on the back plate. llither con struction permits the ready removal of the rellector from the baclt plate. The reflector has its face side preferably covered with aprotecting glass plate e, which is applied to the rim or marginal portion ot' the reflector and is removabiy held in place by any suitable means. 1n the construction represented in Figs. 3 andA G the rim of the reflector is slit ted and bent over the glass plate, as indicated at e5, while in the construction represented in Figs. 16 and 17 the rim of the reflector is provided with 'an annular groove in which the glass plate is held by a divided vvire ring el. The reflector is preferably provided near the glas plate with upper and lower pertorations el, which permit a circulation ot' airthrough the spare between the reflector and the plate for keeping the plate cool and clear. The b acl-z plate is preferably provided in rear of the reflector with a lens or jewel e, which may be illumined in various ways. In the con struction represented in Figs. 3 and 10 the reflector issomewhat smaller in diameter than the inner wall or lining B of the body and leaves an annular space am around its margin through which lie/ht is dilfused rear wardly to the lens. ln the constructioiirep resented in Figs. 141i and 1G tle reflector iV provided with a Small central opening e". through which light passes direcdy to the tant from the llame that they are not liable yto be injured by heat or vobscured by smoke or soot. lThe air passage which envelops this cylindrical reflecting wall B is of uniform .width from the front to the rear end of this wall and is unobstructed, .forming a passage of large carrying capacity, although. comparatively shallow'.
The upper portion ot' the lamp or lantern structure, which contains the coi'itrivances for admitting the air and en'iitting the products o1" combustion, is constructed as tollows: Gr represents an upright cylinder forming the outer wall ot a descending annular air passage g. This vertical cylindrical wall is secured upon the horizontal cylindrical wall t et' the. body portionI by any suitable means in such manner that the air passage r/ connects with the cylindrical or annular air passage a between the body wall A and its lining B. ll represents the metallic chimney which is arranged renlrally within the upright wall (l and which joins at its lower end the upper portion ol' the inner horizontal wall or lining l5 of the body portion. This lining' preferably provided with a short upwardly-projecting collar L, which surroundsjthe opening h1 in the lining, through which` the products of combustion escape therefrom and which pro 105 jects into the lower portion ot the chimney il and bridges the joint between the latter and the lining B. The collar /L is made so short that the lining B can be insertedinto the outer body wall A and the collar i can be introduced into thechimney by a tilting rearward movement ot the lining. I represents an annular horizontal llange which is arranged above the upper end ot' the upright cylinder G and is separated there- .lroi'n by an air passage Thistiange is preferably supported on the cylinder (l by )osts e, Fig. Y, and the inner portion the llange is preferablyturned downi' "diy, as shown at K represents an air injecting cylinder which is arranged between the outer cylindeaG and the chimney H and inside of the ltinge l", being separated from the latter by an air passage cl. This cylinder is provided above the flange l with an upwardly-tlaring portion lng, which extends higher than the chimney ll and is provided it its upper end with an inwardly-projectng flange L. which preferably rises .inwardly and w lich is provided with air inlet 13C vii openings Z. M represents cylindrical collar which extends downwardly from the inner edge oi the llange Lto point at a suitable distance below the top ot the chimney H. This collar M is separated from the chimney by an annular air passage 'In and from the'l to the cylinder K bythe flange L, and the-1 chimney l-l is secured to the collar-N by arms 01, Fig. 12. -Other suitable fastening means mayphowever, be `employed, i desired.
ln the operation of this lamp or lantern `the products oi combustion pass upwardly through the chimneyll and collar M and escape through the openings underneath the top plate lN. Air currents which pass through the space between the top plate N and the lange L may be more or less detlectcd in downward direction. If such a current strikes against the inner side ofthe collar M, it is deflected thereby into the annular space m between the collar and the chimney H, and so reachesl the descending paf" ge y, between the chimney and the outer cylinder Gr, and flows to the burner. Such air currents entering` the top portion of the lantern are by this means prevented from blowing down the chimney with full force, whereby the flame would be caused to smokelor in extreme cases extinguished. Air currents which strike against the upper sloping flange L are'injected into the pas sage m1 between the collar M and the in jecting cylinder K and pass into thehpassage g. Air currents which strike against the upper downwardly-tapering portion 7g2 of the cylinder K' are deflected downwardly vthereby and enter the passage g through the space lvl. Air cur 1ents which strike against the under side of the flange l enter the passage g tbrogli the space z'. All of these ourrents tend to pass downwardly through the passages g and a and maintain the' flow of air in the proper direction to .sustain the llame; but if an ecessive blast should enter these passages it can vent. itself in an upward direction 'through these various inlets, particularly on that side et each inlet which is not exposed to the 'direct force of the blast. A copious supply of fresh air in the proper direction to support the llame is by these devices maintained under all. conditions of movement of the lamp or lantern and ot exposure to air currents, while an cxcrg'sive supply ot air to vthe flame and injurious downward blasts in the chimney are prevented. The lantern. or lamp is there by enabled to sustain a, bright and steady dame at all times.
The lower portion -oli the lamp, in which the oil pot and burner are arranged, is constructed as followsz; P represents t e oil pot, having the usual collar p, in which is seated the burner p1., having the usual perforated 2Q'allery p2, Fig-s0 and 8. gf' is the cylindrical wall or' the air chamber, 'which sur1w rounds the collar 79. 'F1- regresentsthe burner cone, resting, as usual by shoulder upon the perforated gallery 722 and having skirt p4 restingupon the Wall of the air chainber and provided above the latter with air passages or lgierliorations 22". The burner con-e projects upwardly tlirougrh in the lower portion of the Yinner Wall or lining' B of the lamp or lantern, and this opening is preferably formed in a raised substantially horizontal annular diapliragm g, secured in the lower portion of the lining l1. This diaphragm preferably snugly around the burner cone and is provided with perforations QL, through which. a limited amount of air passes l'roni the passage@ to the space within 'the lining l5, which forms the tlamc-clulniber. R- represents the lower collar. or body hoop of the lantern, lwhich preferably llares downwardly and which' receives the rr-,inovuble oil pot P. This body hoop is provided in its upper portion with an upwaidly-tapering or conical annular diaphragln 9', into which the skirt of the burner cone projects in such manner that the per- 'orations p5 of the cone are located above 4this lower diaphragm fr and below the upper diaphragm Q. 1lilhen the oil pot and burner are attached to the body of the lamp or lanternthe air passes from the descending annular passage a into the space between the upper diaphragm g and the lower diaphragm I 7'. The main portion of the air passes from the space through the pertorations 725 in the skirt of the burner cone into the chamber piand from the latter through the peril rated gallery f 2 to the interior of the burner cone. A. comparatively small portion ot' the air supplied through the passage a passes through the perforations of the upper diaphrag'm g into the interior oi the lamp body outside ol1 the burner cone. This air prevents overheating of the flame chamber and also aids in perfecting the coinlmstion. `lhe flame-chamber oli this lamp or lantern is a horizontal cylinder or housing having double walls which are connected at the front and rear, forming' a descending annular air passage which. receives the supply of airv l'roiu above and delivers it below the burner co rilhe latter communicates with the lower ponv an openingy tion of this air passage and projects into tls. llame-chamber. This chamber open the front and rear and has a rioyable reflector and aty the front a movable iframe containing` the liront filass. Upon opening this Haine-chandler at the front or rear the interior of the chainber "an be reached without distui'binglj the intao'rity oli the air passages. Yrllien the rianie anbei has beenopened at the rear7 surfaces the chainbe i and olf the rear reflector can be coiiveniently reached foi.' cleaning and other purposes. I
The oil pot inay be detachably the lamp. body by any si t devices. The preferred 1' sten ng devices which are shown in the draw.' A, are ci structed as follows: The oil pot provided on its upper side with an upwardly-prf ing marginal attaching collar Si. li Q S and. 8, which fits with its enlarged opper por-- tion S1 snugly into the lower cylindrical portion r1 ot' the body hoop l?. and is *l ed to bear with its upper :i shoulder r2 atthe upper end of the drical portion. r1. The collar I5 is 3;. below the enlarged upper portion annular shoulder T represents two horizontal lockingbolts Which are journaled tangentiallyin the lower portion r1 ot the `body hoop on diametri Tally opposite sides tl'nreoli.1 hese bolts are constructed on one side with a retreating or recessed portion. of any suit able shape or construction, so that open. turning the bolts about their aries to l. esent the retreating or recessed side 1nwardly they will not obstruct the interior of the cylindrical portion r1 of the body hoop and perinit the collar S of the oil poty to be freely inserted into the saine or to be removed therefrom, while by tornino' the bolts out of this position portions or the bolts will project inwardly underneath ythe shoulder Sl of the collar S and lock the lat.- ter to the body hoop. This resultgis oonveniently produced by providing caca boit on one side with a concave recess-t, l? 5, S and 9, which is curved concentric wit the inner side ol the lower pi body hoop. 7ilhen the bolts are so tur e that these recesses are presented inwardlY as shown in Figs. and t). they do not ject beyond the inner cylindrical suriftce thc body hoop and the oil pot can be freely inserted or removed. 'in order to locl; the oil pot to the body hoop, the bolts are given half a turn after the oil pot has been in sorted.
