CHARLES GRIFFIN WEBBER, QF FLUSHING, YORK, ASSIGNOB TO 'SARAH A. WEBBER, OF SAME PLACE.

LAMP-BURNER.

SPECIFICATION forming part of Letters Patent No. 294,417, dated March 4, 1884.

Application filed August 10, 1883. iNo'model.)

a citizen of the United States, residing at Flushing, in the county of Queens and State of New York, have invented a new and useful Lam-p, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to lamp-burners,the object being to provide burners with means for readily extinguishing the light without danger of explosion and without requiring the removal of the lamp-chimney or the turning down of the wick. The invention consists in combining with the wick-tube of the lamp a blow-tube whose upper end is provided with a valve for preventing the accidental extinguishing of the light, and whose lower end is connected to a mouthpiece. Y

The invention further consists in the combination, with the blow-tube and its mouth-piece, of a blow-pipe,whereby the light may be readilyextinguished when the lamp rests upon a bracket or other support too highto admit of the use of the mouth-piece of the blow-tube.

The invention further consists in the details v of construction and combinations of parts hereinafter fully described, and pointed out in theclaims.

In the drawings, Figure 1 is a perspective view of a lamp-burner with its top cap raised to show the application of my improvement. Fig. 2 is a vertical section of Fig. 1, and Fig. 3 shows my improved blow-pipe adapted for use when the lamp rests in an elevated position.

A represents a lamp-burner, which may be of any preferred general construction. 13 indicates its hinged top cap, 0 its chimney-guards,

and D the wick-tube.

F represents a blow-tube, preferably arranged parallel with thewick-tube and extending through the perforated diaphragm a of the burner. The under side, f, of the tube F extends above its side f, and the ends f f are preferably inclined to form a seat for a valve, G. The. ends of the latter are bent and perfo-- rated to receive the ends of a pivotal rod or wire, supported onthe outer side of the tube F by soldering or otherwise. The inner side,

5o f, of the tube .F is preferably flush with the 'upper edge of the wick-tube, for a purpose which will be explained.

Tothe lower end of the blow-tube F is secured a mouth-piece, H, whose outer end is enlarged or flaring. This mouth-piece is inclined relative to the tube F, and its outer end projeots below the adjacent edge of the diaphragm of the burner.

From the construction thus described it will be apparent that upon blowinginto the mouthpiece the valve G will be raised and the air discharged in an upward direction against the flame of the wick by reason of the relative arran gem ent of the wick and blow tubes, thus effectuall y preventing any downward draft with in the wick-tube and consequent explosion. The valve G drops by its own weight and rests normally upon the blow-tube,to prevent the ingress of air to the flame, except when lifted by the blowing already described. I In Fig. 3 I have illustrated a flexible blowpipe of rubber, and provided at one end with a metallic tube, 1,'and handle J, and at its opposite end with a mouth-piece,K. This device is adapted for use where thelamp to-be extinguished rests too high up to admit of the blowing directly into the mouthpiece H. In this instance the tubeI is inserted into the mouthpiece H by means of the handle J thus leav-' ing the mouthpiece K of the tube within easy reach.

An important advantage of my invention is found in the fact that by its use only an occasional trimming of the wick is necessary, since to extinguish the flame no turning down or adjustment of the wick is necessary. Where the wick is turned down each time thelight is blownout,itsfrequenttrimmingis necessitated.

My-improvement inno wise affects the regularity of the light, and affords a ready, convenient, and safe means for extinguishing the same.

It will be apparent that many slight alterations might be resorted to in the details of construction of my device without departing from the spirit of my invention; hence I do not limit 9 5 myself to the exact construction shown and described, but reserve to myself the rightto make all such modifications as may properly fall within the scope of my invention;

Havingfully described my invention, what'I IOO I blow-tube, and a mouth-piece secured to the lower end of the blow-tube, substantially as set forth.

- 4. The combination, with the wick-tube of a lampburner, of a blow-tube whose upper edge is flush with the upper edge of the wick-tube, and an inclined mouth-piece adapted to guide the draft in an upward direction, substantially as set forth.

5. The combination, with awick-tube and a blow-tube provided with a pivoted valve and a mouth-piece, of a blow-pipe adapted to beinserted into said mouth-piece and provided with a handle, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
