.To all whom it may concern:

ing purposes on railways, a glass reflectorQ rlhe obJect of this Invention is to provide a suitable holder for supporting such a reflector within the lantern; andit consists,

broadly, in a channeled seat for the rim of the reflector, and a stem or standard for supporting this seat, which is attached to either the body of the lantern or the font 'of the lamp.

rlthe invention is illustrated inthe accompanying drawings, which show several modifications of it and in which- Figure l is a plan section of the lantern through its lens and reflector; Fig. l2 is avertical central section of the lantern through its lens and reflector; Fig. 3 is a rear Aelevation of the lamp font, showing the forin of reflector holder illustrated in Figs. l and 2; Fig. l is a plan section of the lantern taken above the reflector and lens and showing a modified form of reflector holder; Fig. 5 is a rear elevation of the lamp shown in Fig. 4; Figs. 6 and 7 are side and rear elevations, respectively, of the lamp showin-g a further modification of form of the reflector holder; Figs. 8 and 9 are side and reare'le-y vations, respectively, of the lamp showing a still further modification of the reflector holder. n n

The reflector used in the lantern illustrated is marked l5 in the drawings, is made of O'lass, and is a concave-convex disk, its concave face being smooth and its con-y veX or rearward face being annularly ribbed,

the ribs being so arranged that when the reflector is properly positioned withl reference to the flame the lig it rays emanating there from are directed backwardly to it, and

`from the llame to the lens.

Y y portanti, therefore, to properly support the Be it known that l, WILLIAM S. Hariri/1 a citizen of the United States, and resident reflector relatively to the flame of the burner:

The body' of the lantern is designated'17,v

the font of the, lamp used therein, l8,and`

its ,burn-er, 19. The font secured in proper position by means of a chair composediof the flanges 20, n2l and 22, rising fromthe -floor of the lantern, a yspring 23, secured to"` one ofA the flanges, hooking kover 'one corner`l` of the font to retain it in the chair. ln the forms olf reflector holder shown in Figs. lj to 9,`the reflector is supported "by the font. of the lantern, the support, in the construc-L tion of Figs. 1,2and 3, taking the form ofA a single standard 24 secured to and rising from the top of the font, its upper redgeconforming in shape to the rim -of the ref flectorvl and extending through approxi-k mately a half circle and'being channeled, as

' plainly shown in Fig. l, to form ax seat for th-e reflector.` A

A spring 25, represented as a piece of wire, issecured to the standard 24 and eX tends upwardly along .the rim of the reholds it in place against any arring to whichL the lantern may be subjecte In the construction illustrated in Figs. Il to 9 the reflector holder is sectional in form,

comprising a plurality of posts, as 27, 28'l and 29,A in Figs.r 4 and 5, 30, 3l, in Figs. 6 and 7, 32, 33, in Figs. 8 and 9. All of these posts Aare forked at their upper ends to re" ceive the rim' of the reflector, as in a channel.1

yReferring to Figs. 4 and 5, the post 29 is coincident with `the vertical diameter `of the reflector and constitutes a vertical support therefor. The posts 27, 28, engage, the side vedges ofthe reflector and serve asv lateral stays, at least one of theseposts, as 27risin'g' above the horizontaly diameter of. the.:reflec-` tor, thereby providing with thepther two-5 posts a support which yengages 1t through finore than half of its circumference. Thesey of such length that they enga-ge the refiectorbeloW its horizontal diameter. A spring arm 34 rises from the font 18 back of the reflector, and has its upper end bent forwardly and curved to spring over the upper,

edge thereof, thus holding it to the seat provided by the forked ends of the posts 30, 3l, by a yielding pressure.

In the construction illustrated in Figs. 8 and 9, the posts 32, 33, are substantially of the same form as the posts 30 and 3l, but are projected,upwardly from the point at which they first engage the reflector and bent to conform to the rim thereof, their upper ends extending above its horizontal diameter and being provided with inturned lugs 35, 36, Which form a continuation of the channel seat. AThese posts are preferably of elastic sheet metal and engage the rim of the reflector with a yielding pressure.

I claim as my inventionl. In combination, a lantern having a font, a reflector, and a support for the refiector comprising a standard rising from thefont and having a channeled seat for receiving the edge of the reflector, and a spring arm having a fixed anchorage and engaging the reflector at its rim above its Vhorizontal diameter.
