Application filed June 24, 1911. Serial No. 635,147.

T0 at whom 2'6 mag concern Be 1t known that we, PnnoY HAUSER and ALBERT Gr. MOLAUGI-ILIN, both eltizens of the- United States of America, reslding 1n the city of Altoona, county of Blalr, and State of Pennsylvania, haveinvented a certaln new and useful Improvement in Candle- Lamps', of which the following. is a true and is pressed byresili'ent means located within thecandle 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.-

The object of the presentinvention is to provide an improved candle holder of the kind specified, which in addition to being comparatively simple in construction and reliable and efficientin normal operation, is adapted to eifect 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 ofthe lamp and to permitthe ready removal of the melted candle body material, which may accumulate in the lamp.

The various features of novelty which characterize ourinvention arepointed outv with particularity in the claims annexed to and forming a part of thisspecification. For a'better understanding of the invention, however, and the advantages-possessed by it, reference should be had to theaccompanying 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 embodying ourinvention. 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.4 is a section of the candle tube'on the line 44 of Fig. 2.

In the drawings, A, represents the-candle tube or tubular-lamp body, which has-an internal diameter appreciably greater thanv the diameter of thecandles received therein. The tube Amay be provided with the usual supporting bracket A and is closed at its lower end by the cap A which may be brazed in place. To the upper enduof the tube there is secured an. end member B. As shown, the end member B comprises a l tubular body portionte-lescoping on the upper end of the member A and is provided at its lower end with a bead B. Thezlatter is notched, as indicated atiBF" in Fig. 4., to permit thelocking projection A formed on the candle tube A to enter the bead, whereby the end member B may be thereafter locked in place by giving it a slight rotative movement. The' member B terminates at i'ts.up-

per end ina'conical portion through which. there is. formed a central aperture B In the constructlon illustrated, an annular candle stop member C is secured to the member Batthe base of the conical portion/B n as by spinning the member B to form. a bead B surrounding-the periphery of the menr ber C. The member C is providedwith a dependingflange C? which .forms a tubular guideiof substantially the same diameter as, and snugly receiving .the "upper-end of the candle-C mounted in-thelamp, The central aperture C of the body portion of the member C is of less-diameter than the candle C and the portion of the member C projecting across theebore of the guide C and formingiin effect an inturned lip at theupperend of that guide, forms the portion .of the stop of the lamp against which the up per end of the candle directly bears. With the construction described, it will be observed'that themember O and the head portion B of the member B uniteto form an annular trough B located above and' sL11'- roundingv the aperture G.

The candle follower engaging :the bottom of the candle comprises .a body portion D in the form of an inverted cap, which is united atits lower end to a cylindrical guide portion D, fitting against the inner wall of the candle tube, an annulargroove' D being formed in the follower between the body portion D and the upper end of the guide portion D. Theupper candle engagingend of the follower is flat except for a candle centering projection D andis of a diameter somewhat greater than the diam eter of the aperture C. The member D isso shaped, however, relative to the tubutube by the spring E which extends between the follower and the bottom cap A and for convenience in manipulation, may be advantageously connected at its upper end to the follower, as by brazing the spring and follower together.

F, represents anannular 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 G. H, represents a soot collecting canopy extending over the top of the lamp chimney and supported from the bracket A by the post H.

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 engaging the followerD and centered by the projection D The candle may advantageously be formed with a small central cavity in its lower end to facilitate the centering operation. After the candle is in place the cap B is again secured to the candle tube with the upper end of the candle snugly received in the follower 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. When the wick is ignited,

the candle material melted by the heat is substantially prevented by the unmelted portion of the candle and its engagement 7 n with the stop Cand guide C from passing belowv the stop C and from running down the candle, and any melted candle material which may rise above the candle stop C proper collects in the trough B When the ,7 consumption of the candle is continued until all thewax or tallow of the candle is entirely melted, the follower D D engages the candle stop C and takes the place formerly occupied by the candle in forming a substantially tight joint with the candle stop to thereby prevent the melted wax or tallow, of which there is considerable at the instant at which the last portion of the candle body melts, from passing below the stop Gin other thanminute quantities. In

' consequence, practically all of this melted wax or tallow is held above the candle stop and is consumed before the flame from'the wick of the candle dies out. .Any small amountof melted wax or tallow which may run down the side of the candle or the upper portion of the follower or along the guide (3 will collect in the trough D and in practice wehave found that a trough D of the capacity indicated by the relative proportion of the parts shown by the drawing, is ample to prevent unobjectionable deposit of wax or tallow on the inner wall of the candle tube in the ordinary operation of the lamp. It is of course apparent that any deposit of wax or tallow in the troughs B and D may be readily removed, as for instance, at each candle charging operation. The ease with which the accumulated candle material may be removed from these troughs or spaces and the avoidance of any deposit of wax or tallow on the inner wall of the candle tube in normal operation, are matters of considerable practical importance, particularly with candle lamps used in railway cars. As heretofore constructed, the accumulation of wax or tallow within the candle tubes has necessitated frequent cleaning out operations, ordinarily involving the use of steam as a cleaning and heating agent, and in all events, constituting a source of annoyance and expense.

lVhile in accordance with the provisions of the statutes we have illustrated and described the best form of our invention 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 without 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:

1. A candle lamp comprising in combination a candle tube provided at its upper end with an apertured stop for the upper end of an inserted candle and above said stop with a collecting trough surrounding the aperture in said stop, said aperture being of less diameter than the body of the candle and having the candle wick projecting through it, and'a spring pressed follower mounted in the candle tube and formed with an upper end face adapted to engage said stop at the margin of said aperture when not held out of contact therewith by the body of an inserted candle.

2. 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 with an aperture of less diameter than the body of the candle through which the candle wick projects and being provided with a depending circular flange smaller in diameter than the surrounding candle tube and surrounding said aperture and forming a guide snugly receiving the upper end of an inserted candle, and a spring pressed follower mounted in the candle tube and comprising a body portion in the form of an inverted cup adapted to enter said guide and have its upper end face seated against said stop at the margin of said aperture when not held out of contact therewith by the body of an inserted candle, said follower comprising also a lower guide portion engaging the wall of the candle tube and being formed with a collecting trough surrounding the base of said body portion and registering with said depending flange.

3. In acandle lamp the combination of a candle tube comprising a body portion and a telescoping member detachably secured to the upper end thereof and formed with a conical and apertured upper end, an annular candle stop member secured to said end member at the base of said conical end portion, a depending cylindrical flange secured to said candle stop and surrounding said aperture and forming a guide adapted to snugly receive the upper end of the candle inserted in the lamp, 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 follower mounted in said candle tube and comprising a body portion in the form of an inverted cup adapted to enter said guide and engage said stop at the margin of said aperture when not held out of contact therewith by the body of an insert ed candle, said follower having a guide portion engaging the inner wall of the candle tube and a trough formed at the base of said body portion.
