Specification .of Lettersifatent. I

Patented Nov. 11, 1913.

Applicationifiled. September as, 1912! Serial No. 720 951 Our present invention relates "to candle lamps of the kind in which a .candle is movably received in a candle tubeand the latter is provided with a stop at its upper end against which the Hip-P 1 end of the candle is pressed by resilient means located within the candle tube and acting against the lower end of the candle, the stop being formed with an aperture of less diameter than the candle through which the wick of the-candle projects, and above which combustion takes place. i

The object of the present invention is to provide an improved candle holder .of the kind specified, which in addition .to being comparatively simple construction and reliable and .efficient in normal. operation, is

slight rotative movement. term nates-at itsupper end n a conical porcentral aperture B adapted to effect a substantially. complete combustion of a candle used in it, and the avoidance-of an objectionable accumulation of the melted candle body material in the,

candle tube proper .or other portions of the;

lamp ,and to permit the ready removal of the? melted candle body material, which maypaccumulate in the lamp 1 The various features. .ofnovelty which, characterize our invention are pointed out with particularity in the claims annexed to and forming .a ,part .of this specification. For a better understanding of the inven-; tion, however, and the advantages possessed by it, reference should behad to the accom panying drawings and descriptive matter in which we have illustrated ,and described a preferred form .of apparatus in which our invention may be embodied.

Of the drawings, Figure 1 is an elevation of a candle lamp embodyingkour invention. Fig. 2 is a section on the 'line 2 2 of Fig. 1; Fig. :3 is a partial section taken similarly to Fig. 2, but on a larger scale than that figure, and Fig. 4c is a section of the candle tube on the line 4 4: of Fig. 2;

In the As 'ii prese its the candle tube'tor tubularilamp body, which has an internal diameter appreciably greater than the diameter of the candles received therein. The tube A may be provided with the usual supporting bracket A- and is closed at its lower, end the cap A which may be brazed in place. To the upper end of the tnbeA there is removably secured an .end vmember As shown, the end member '13 comprises a tubular "body portion telescoping on the upper end of the member A and s provided at its lower end with a bead B". The latter is notched, as indicated at 13 in Fig; 4, topermit the locking projection. A formed on the candle tube A to enter the .bead, whereby the end member may be thereafter locked in place Joy giving 'ita- The member T3 not B ithrough which there is formed a In the construction illustrated, an annular candle stop member G preferably as shown inthe form-of a flat apertured disk of sheet metal is secured to the member B at the base of the conical portion B as by spinningthe member 13 to form a bead B surrounding the periphery of the member "G. The member C is rovided at its under side with a tubular candle guide '0 which may be soldered at its upper .end to the disk G. The guide C is of substantially the same diameter as, and. snugly receives the upper end of the candle .X mounted in the lamp. The central aperture C of the body portion of the member G is otless diameter than the candle body X and the portion .of the member Oproject ing across the "bore of the guide 0 and forming in effect an inturned Ilip atthe an imnular trough B located above surrounding the aperture O". v

The candle follower D which normally engages the bottom of the candle is cupshaped and may be formed out of pressed brass, or the like, and is of a diameter at'its upper edge, but slightly less than thein- V terna'ldiameter of the candle tube. Preferably as illustrated, the parts are so proporti ned that the cavity in the pper side candle stop disk C, as shown in Fig. 3, while at the same time an appreciable space is left between the bottom of the follower and the soldered or otherwise lower edge of the tubular candle guide 0 The follower D is resiliently urged toward the upper end of the candle tube by the spring .E which extends between the follower and the bottom cap A Advantageously the upper end of the'spring E is attached to the follower D.

F, represents an annular member, secured to the candle tube adjacent its upper end and provided with 'draft apertures; F at its lower end, and serving to support the lamp chimney Gr. H represents" a soot col- -lecting canopy extending over the top of the lamp chimney and supported from the bracket A by the post H. v

To charge the lamp with a candle, the cap B is first removed and'the candle is then inserted in the tube with its lower end received in and centered by the hollow follower D. After the candle is in. place the cap Bis again secured to the candle tube withthe upper end of the candle snugly receivedinthefollower guide C and the upper surface of the candle bearing against the candle stop C and with the candle wick projecting centrally through the aperture C. 35

In operation with the .candle wick ignited, the spring-pressed follower D constantly feeds the unconsumed portion of the candle body X upward thereby holding the solid portion ofthe candle against the stop,

until the shortening of the candle body permits the upper margin of the follower D to impinge against the underside of the candlestop disk C.

f "Prior to the engagement of the follower D with the stop G, the snug engagement of the unmelted portion of the candle body with the stop G and guide 0 prevents any ap-' preciable amount of the melted candle material from passing below the stop and guide and running down the side of the candle.

, Any small portion of the melted candle material which may pass below the guide C is eventually received within the hollow follower D and has no opportunity to come in contact with the interior wall of the candle tube. Any melted candle material which may rise above the candle stop G proper,

collectsin the trough B and is ultimately consumed. When the shortening of the solid portion ofthe candle body permits the follower D to engage the stop C, the further combustion of the remaining candle material is not thereby prevented. On the contrary, unless the candle flame is purposely extinguished, combustion will ordinarily proceed until practically all of the candle material is consumed. As the combustion of the candle material proceeds after the follower D engages the stop C and the candle flame lowers relative to the candle stop, the consequent rise in temperature of I the candlesto-p C, guide C and eventually of the follower D, soon results in melting all of the remaining candle wax or tallow. At its maximum this melted candle material is ordinarily suflicient in amount to fill the follower D to'a level, indicated in Fig. 3 by the line X which is appreciably above the lower end of the guide C The clearance space provided between the lower end of the stop C and the bottom of the follower E permits the ready escape of melted candle material from the interior of the guide G into the portion' of the hollow follower D at the outer side of the guide in the initial portion of this final stage of the candle consumption. This decreases the depth of the pool of the melted candle material contained within the follower and correspondingly decreases the liability of the candle wick being submerged therein with a consequent premature extinction of the candle flame. As the combustion of the melted candle material thereafter continues, the ample clearance space between the lower end of the guide C and the follower permits the melted candle material to flow toward the bottom of the hollow follower, and in practice, under ordinary conditions, almost all of the candle material will be consumed before the candle flame will be extinguished from natural causes; and there is practically no possibility of sufficient candle material being left unconsumed to serve when cold as a cement.- ing bond between the lower end of the guide C and the follower D.

It is, of course, apparent that any candle material which may have collected in the trough B during earlier stages of the candle operation will naturally drain out of this trough and beconsumed in the final stage of operation. v

Regardless of how soon the candle flame is extinguished after the stop C is engaged by the follower D, it is obvious that the capacity of the cavity formed in the upper side of the latter is more than ample to hold the remaining candle material. Furthermore, the snug joint between the upper end of the follower and the stop C will prevent any of the melted candle material from passing out of the follower and into contact with the walls of the candle tube proper under the jars or agitation to which the candle lamp may be subjected in ordinary operation.

It is, of course readily apparent that any candle material remaining in the follower D after the candle flame is finally extinguished may be quickly and easily removed when the candle lamp is recharged. The avoidance of any accumulation of candle material within the candle tube suflicientto interfere with the proper operation of the lamp, and the ease and rapidity with which the only portions of the candle lamp in which melted candle material may collect,

may be cleaned, are characteristic features of our lamp of great practical importance, as they save time and expense which have heretofore characterized the use of candle lamps, particularly in railway service wherein it has been commonly necessary to subject the candle tubes to frequent cleaning out operations involving the use of steam as a cleaning and heating agent.

While in accordance with the provisions of the statutes we have illustrated and. described the best form of our invent-ion now known to us, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed with out departing from the spirit of our invention, and that certain features of the invention may sometimes be used with advantage without a corresponding use of other features.

Having now described our invention what we claim as new and desire to secure by Letters Patent is: t

A candle lamp, comprising in combination a candle tube provided at its upper end with a stop for the upper end of an inserted candle, said stop being formed by a disklike body extending across the tube and formed with a central aperture and being provided with a depending cylindrical guide surrounding said aperture and adapted to snugly receive the upper end of the inserted candle, the internal diameter of said tube being greater, and the=diameter of said aperture being less than the diameter of the inserted candle, and a spring pressed cup-shaped follower mounted in saidcandle tube, and adapted tosurround saidtubular guide and engage said disk when not held out of contact with the latter by an inserted. candle, said guide and follower being so relatively proportioned that a clearance space exists between the lower end of said guide and said follower when the latter engages said disk.
