SPECIFICATION forming part of Letters l-atent No; 609,192, dated August 16, 1898.

To all whom it may concern:

Be it known that I, CHARLES BERGENER, of

Letters Patent No. 262,247, dated April 17,

My present invention relates to improvements in that class of lamps adapted to be used on bicycles or other vehicles, is anim provement upon the lamp shown in my pend- 2o ing application for Letters Patent, Serial No. 604,996, filed September 5, 1896, and has for its object to improve the construction and operation of said lamp, whereby the supply of air to the burner beneath the burner-cone will be sufficient to cause the maximum flame whether the lamp be still and liable to be subj ected to blasts of air from any direction or is moving in one direction and subjected only to the blast caused by the movement of the vehicle; and to these and other ends the invention consists in certain improvements in construction and combinations of parts, all as will be hereinafter described, and thenovel features pointed out particularly in the claims 3 5 at the end of this specification.

In the accompanying drawings, Figure 1 is a side elevation of a lamp constructed in accordance with my invention; Fig. 2, a plan View of the same with the top section re- 0 moved; Fig. 3, a central vertical sectional View; Fig. 4, a horizontal sectional view on the line so a; of Fig. 3; Fig. 5, a vertical sectional view on the line y 'y of Fig. 2; Fig. 6, a sectional view on the line a 20f Fig. 2, show- 5 ing the bottom portion of the central section of the lamp only; Fig. 7, a section on the line a b of Fig. 5, looking upward; Fig. 8, a sec= tion on the line 0 d of Fig. 2.

Similar reference-numerals in the several figures indicate similar parts.

As in the lamp shownin my prior application, the present invention embodies generally a tubular body 1, having a removable top 2,'connected to the body by a bayonet or other suitable catch, as shown, and at the bottom a removable oil-pot 3, having an upwardly-extended perforated flange 4, entering a correspondingly-perforated flange 5 on the body, the flanges being connected by studs 6, entering suitable slots formed in one of the flanges, whereby an air-space will be formed between the top of the oil-pot and a plate 9 in the body.

8 indicates an ordinary slip-burner resting in the oil-potand heldin position by having its upper portion engaging with a bottom plate 9, between which and the burner-cone 10 is formed an air-chamber 11. At the rear of this air-chamber is an upwardly-extending air-tube 12, having an injector 13 at its upper end, and suitable holes 14 are provided in the upper portion of the body opposite the entrance tothe injector. The front of the body is provided with a gogglelo, in which is located a window, or, preferably, a lens 16, and behind the burner is a removable reflector 17. The sidesof the body are also provided with the usual windows 18, one or both of which is adapted to be opened for the purpose of lighting the wick. 1

Extending around the body of the lamp and preferably in the plane of the injector 13 is an air-director composed of

plates

19 and 20. The channels in the top and bottom of this director and the passage between the overhanging edges of the two plates communicate with the end of the injector 13, as in my prior application.

21 indicates tubes extending Vertically on opposite sides of the goggle or front of the lamp and communicating at their lower ends with the air-chamber 11 beneath the burnercone. Their extreme upper ends are closed, though openings are formed in the sides next the body into which the edges of the

plates

19 and 20 enter, and in the upper end of these tubes are provided small dividing-plates 22, extending part way across the air-passage formed between the

plates

19 and 20 of the air-director and extending below said director a short distance between the tube and the body of the lamp, as shown particularly in 7 Figs. and 7, the construction being such that as the lamp moves forward a portion of the air in the central channel of the annular air-director and beneath the same will be delatter, so that there will always be a sufficient supply of air beneath the burner-cone to support combustion and produce the maximum flame.

In order that the air passing down the tube 12 may not impinge directly upon the flame, I provide in the chamber 11 a perforated guard or deflecting plate 23, extending partially around the burner-opening and between the latter and the opening of the rear tube 12 and connecting with the body at the sides, whereby the current of air descending through the tube 12 will not impinge directly upon the flame, but will be divided and distributed in the chamber in the best manner. The exact location and construction of this deflecting-plate 23 is not essential, excepting that it shall be disposed in such manner as to prevent the direct blast of air from tube 12 upon the flame, although I prefer the arrangement shown, as I find in practice that it is desirable.

The sides of the lamp-body 1 are perforated at 26 in order to afford a supply of air above the burner-cone, and inside of the bodyIarrange vertical plates 27 to'prevent the air entering these perforations from impinging directly upon the flame.

I do not claim herein the construction of the lower part of the lamp-body and the oil-pot attached in the manner described, as this is claimed in my pending application, Serial No. 611,385, nor do I claim herein the combination of the body, director, and a single air-tube at the rear having the injector at the top, as this is claimed in my pending application, Serial No. 604,996.

I claim as my invention 1. In a lamp, the combination with the body, the burner, the burner-cone, and the air-chamber beneath the burner-cone, of the rear air-tube separated from the body and having the injector at its upper end and communicating with the air-chamber, and the side tubes closed at their upper ends and also connected to the air-chamber and having the openings and the dividing-plates therein, substantially as described. v

2. In a lamp, the combination with the body having the window at the front, and the air-tube at the rear separated from the body and having the injector at the top, of the burner and its cone, the air-chamber beneath the cone with which the rear tube connects, the air-director extending around the lampbody,the separate side tubes having the closed upper ends and connected with the air-chamber and having the openings in proximity to the air-director, substantially as described.

3. In a lamp, the combination with the body, the burner and cone, and the air-chamber beneath the latter, of the rear air-tube separated from the body, having the injector at its upper portion and communicating with the air-chamber and also with the body above the burner, the side tubes closed at their upper ends and open near said ends on the side next the body and having the dividing-plates in said openings, and an annular air-director cooperating with the side and rear tubes.

4. In a lamp, the combination with the body having the window at the front, the burner, the burner-cone, and the air-chamber beneath the cone, of the rear air-tube having the injector at its upper end, the air-director having the upper, lower and intermediate air-channels, the side tubes connected to the air-chamber having the openings at their upper ends, and the dividing-plates in the openings, substantially as described.

5. In a lamp, the combination with the lamp-body having the window, the burner, burner-cone, and the air-chamber beneath the latter, of the side air-tubes having the closed upper ends and communicating with the airchamber and open at their upper por tions on the sides next the lamp-body, the vertical dividing-plate in said openings, and the horizontal air-director having an annular passage and the channeled lower side, substantially as described.

CHARLES BERGENER.
