To @ZZ whom it may concern,.-

Beit known that I, FRANK RHIND, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Argand Burners and Lamps; and I do hereby declare the following to be a full, clear, and exact description of theiuvention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawing, which forms part of this specification.

My invention relates to an improvement in Argand burners and lamps; and it consists, rst, in an Argand burner, in the combination ofthe wick-tube, the spreader, adeiiectingring which conducts the air to the, ilame, a support for the ring, and a support for the chimney, the ring being provided on its outer side with slotted wings which are adjustable to the chimney; second, in an Argand burner, the combination of the wick-tube, the spreader, and a cone which is applied to the outer side of the wick-tubc, the cone being provided with a deflecting-ring upon its top and a support for the chimney at its lower end, and contracted at or near its center, so as to fit f tightly upon the wick-tube, all of which will be more fully described hereinafter.

The object of ,my invention is to so coustruct the different parts of the burner that the heat from the deflecting-ring is transferred through wings connected thereto to the chimney, and the cone kept cool by having all of the air which is fed to the burner from the outside made to pass through it, and thelamp thus prevented from becoming intensely heated, as is always the case where a" large Argand burner is used.

The accompanying drawing represents a Vertical section of a lamp embodying my invention.

A represents the lamp-bowl, upthrough which the hollow or tubular wick-tube B passes in the usual manner. All of the air which is fed to the burner .from the inside passes through the perforations at C, and then up through, the tube to the flame.

Upon the outside of the wick-tube,at any suitable distance below its top, is the concave perforated support D, upon which the perforated cone or cap G rests. The lower portion, H, of this cone is spread out to any suitlower portion of the chimney. At the top of 6c the perforated part I the cone is contracted,s o as to fit tightly against the outer side of the wicktube, not only for the purpose of holding the cone in position, but to prevent the air which passes up through the support D from passing directly up the wicktube. This contracted portion serves to turn the rising currents of air out into the chimney forthe purpose of keeping both the lower portion of the chimney and the burner cool.` From this contraction the burnerA expands outward au d upward to the deilecti ngring L, which forms the top ofthe burner. The

portion O below the ring is perforated, so that v the air from the bottom portion of the chimney can pass through it to be-fed to the llame from the under side of the deflecting-ring. On the outer side of this deiecting-ring are formed the wings or springs P, which serve both to hold the chimney in position and, by coming in contact with the inner side of the lower end of the chimney, to conduct away the heat from the deiecting-ring, and thus keep this portion of the burner cool. wings also serve to prevent the air in the lower portion of the chimney from rising upward, and thus forcing it to pass through the perforated part O. If the wings were not used in connection with the ring, the chimney could not be made to fit, and too much air would pass up the chimney without coming in contact with the flame, thus causing a red instead of a white flame. The wings and the ring coact for the purpose of producing a more perfect illumination than can be produced without them both. y

rIhe body Aof the cone acts only as a support for thering and wings, and to support the chimney in position. The chimney need not be forced downward as far as shown in the drawing, as it can be supported higher up, if so desired.

As the Argand burners have heretofore been constructed the delecting-ring becomes intensely heated, and this heat being commur These IOt nieated to the other parts of the burner7 the lamp becomes so intensely hot that it not only becomes dangerous but unpleasant to handle. The ring being brought in contact with the chimney by means of the wings, and the air being made to pass back and forth through the burner, the burner is always kept cool, and hence this difficulty is entirely overcome.

Having thus described my invention, I clailnl. In an Argand burner, the combination of the wick-tube, the spreader, a deilectingring which conducts the air to the flame, and which is provided ou its outer side with a slitted flange forming wings which adjust themselves to the chimney, a support for the deiiecting-ring, and a support for the chimney below The slitted flange, substantially as showni FRANK RHID.
