SPECIFCATIGN forming part of Letters Patent No. 645,006, dated March 6, 1900. Application-filed August 3, `1899. Serial No. 726,048. (Nit model.)

To @U whom it may concern: Be it known that I, JOHN M. PFAUDLER, o Rochester, in the county of Monroe and State of New York, have invented certain new and usefullmprovements in Lamps; and I do hereby declare the following tobe a full, clear, and enact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the o reference-numerals marked thereon.

My present invention relates to improve-V ments in lamps, particularly that class em- -ploying round wicks, though some of the features areapplicable to other forms, and has for its` objects to' improve the construction and operation of the various parts, all as will be hereinafter described, and the novel features pointed outin the claims at the end of this specitication.

In the drawings, Figure 1 is a sectional view of a lamp fount and burner constructed in accordance with myinvention. Fig. 2isa side elevation of the burner. Fig. 3 is a similar view showing the chimney gallery or support in the elevated position. Fig. 4 is a sectional view on the line 4 4 of Fig. l; and Fig. 5 is a View, partly in section, showing the construction of the wick-raiser. Fig. 6 is a per,- spective View of the extin guisher-rin g and its operating-lever.

Similar reference-nu 1n erals indicate similar parts.

The lamp-body consists of Vthe oil font or reservoir,having the hollow cylindrical drafttube 2 arranged centrally therein, and, eX- tending upwardly, supports the perforated spreader 3 and is surroundedby the burner, supported on the top portion 4 of the fount.

The burner embodiesthe circular ring or base 5, secured to the internal tube or sleeve 6, adapted to surround the wick, and extend upward to the upper extremity of the drafttube 2 and having the rim '7 threaded upon its outer edge and adapted to be secured into the top 4 of the fount.

8 indicates a ring secured upon the interior of the rim 7, having mounted upon it the i shell or casing 9, forming they exterior of the burner. The chimney-gallery rests upon the top of the casing 9 and in the present construction embodies the ring 10,the springfingers 11, the globe or shade support 12, the skeleton plate 14, connected thereto, and the perforated cone-shaped plate 13. Extending downwardly from the ring 10 is a collar or skeleton plate 14, fitting the interior of the burner-shell 9 and provided with the spiral car-tracks 15 and the Vertical Ways or guides 16. Revolubly mounted upon the flange 1S of the shell 9 is a collar 17 having screws or from their lower sides and arranged parallel i to the ways 16, which facilitate the removal of this mechanism from the burner-body when desired. As the ring or collar 17 is revolved the pins 19 operate against the sides of the ways 16, revolving the skeleton frame 14 upon the burner, causing the inclined or spiral ways 15 to be moved against the stationary pins or studs 21 and to be thus elevated. By this construction the operator is only required to rotate theV collar 17, and the necessity of following the chimney-gallery in its ascent with the hand is entirely obviated.

The upper end of the draft-tube 2 is provided with a series of perforations adapted to register 'with apertures 23 in the distributer 3 to allow air to pass into the upper end of the wick to facilitate combustion. The

spreader 3 is fitted loosely into the upper end of the draft-tube 2 and secured in position by means of pins or lugs 24, projecting inwardly and adapted to be engaged beneath the annular rim 25, cut away at 2G upon opposite "sides, as shown in dotted lines, Fig. 1, and mounted upon the ring 27', secured upon 6o pins 19 operating through horizontal slots 20 r vof the extinguisher sleeve or tube 30.

the interior of the draft-tube. 28 indicates a series of apertures to permit the escape of any oil that may have worked over the top of the tube 2 or through the apertures 23 while the wick has not been lighted, and for the lsame purpose I provide apertures 29 in the burner-base 5.

'The upper end of the distributer 3 ilares outwardly over the annular wick-recess between the draft-tube and the inner portion 6 of the burner. The extinguisher is constructed of a sleeve or tube 30, capable of vertical movement on theV tube G, its top nor-v mally resting in line with the top thereof, and supported upon the lower end by an annular flange 3l, secured to the burner by arms 32. The vertical movement of the extinguisher is accomplished by means of a lever 33, pivoted at 3 4 to the burner-shell 9, having the bifurcated ends slotted at 35 and engaging pins 3G, vlocated upon the opposite sides The latter is guided in its movement by the tube G and held in its elevated position in engagement with the overhanging edge of the defiector by frictional engagement between the parts, a portion of the lower part of the extinguisher sleeve or tube being cut away, leaving the ribs 37, which may be bent inwardly before the tube is positioned to create the desired friction between the parts.

As before mentioned, the deiiector 3 is loosely mounted upon the upper end of the draft-tube and prevented from excessivevertical movement by means of the pins 24,which are normally slightly below the rim 25 of the ring 27. By this arrangement the deflector is allowed to yield when engaged by the eX- tinguisher and t0 completely close the top of the latter, preventing the escape of smoke or other obnoxious gases when the flame is extinguished.

The lamp-wick 40 is of course adapted to be raised or lowered to give the desired height of iiame, and for this purpose I provide a wick-raising device arranged within the fou nt and consisting of a vertically-movable ring 4l, surrounding the wick and carrying two oppositely-arranged wings or engaging members 42, hinged thereto at 43 and adapted to extend upward,surrounding and engaging the wick at a point within the burner-tube 6. The wings are formed from thin sheet metal and are adapted to lie against the wick and to be held in engagement therewith by the burner-tube 6, and to insure the even movement of the wick the upper edges of the wings are provided with inwardly-projecting teeth or prongs, (not shown,) and other projections upon the sides of the wings bent inwardly from the V-shaped apertures 44 ene gage the wick securely. The hinged connection between the ring '4l and the wings permits the latter to be separated, as shown 'in dotted lines, when the burner has been removed, allowing the wick to be withdrawn and a new one substituted when desired. Arranged upon one side of the ring 4l is anarm 45, provided upon its extremity with a nut 46, engaging a revoluble post 47, journaled upon its lower end in a bearing 48 and having the quick thread 49. The upper extremity of the post projects through the screw-cap 50,

54, located at the side of the fount, which arrangement centers and guides the wick-raising mechanism and also prevents the nut 46 from being moved out of alinement with the aperture 5l either in removing'or inserting the post. l.

In order that the amount ot' o-il contained in the lamp can be readily ascertained at any time or during the filling operation, I provide an automatic indicating device arranged within the fount and visible through a window or aperture 60, provided with a transparent covering. Pivotally mounted upon a sup-` port 6l is an upwardly-extending arm G2, carrying a curved indicating-plate 65, provided with suitable markings to indicate the level ofthe oil. Rigidly attached at an angle to the said arm is an extension 64, provided at its extremity with a iloat, adapted to rest upon the surface of the oil, and as the heightl of the latteris changed to move the indicator 63 correspondingly.

The improvements described are capable of being fitted to lamps already in use. The extinguishing device can be applied to any IOO lamp ot' the class described having an external wick-*tube and the spreader provided with the broad top with which to cooperate.
