ARGAND LAM P.

SPECIFICATION forming part of Letters Patent No. 444,867, dated January 20, 1891. 9 Application filed May 7, 1890. Serial No. 350,960. (No model.)

To all whom it may concern:

Be it known that 1, JAMES H. WHITE, a citizen of the United States, .residing in the city and State of New York, have invented an Improvement in Argand Lamps, of which the following is a specification.

In my improved lamp the wick-tube that surrounds the Argand wick, instead of being parallel and extending down into the reservoir, is bell-shaped and the lower flaring end rests upon the top of the reservoir, the object being to lessen the heat that is conducted down to the wick and reservoir and to cause any vapors from the oil that may form within the reservoir to be directed up through this bell-shaped wick-tube to the flame, instead of escaping into the room. The removable airdistributer sets around and is supported by this bell-shaped wick-tube and is locked down to the reservoir. The wick-raiser is of sheet metal corrugated to render it elastic, and is provided with a loop and connected to the rod that passes up through the top of the reservoir. The top of the reservoir is sufficiently open to allow for the insertion or removal of the wick and wick-raiser.

In the drawings, Figure l is a vertical section of the lamp. Fig. 2 is an elevation of the wick-tube detached. Fig. 3 is an elevation of the air-distributor and lock; and Fig. at is a plan view of the wick-raising band.

The reservoir A is of ordinary sine, with the central air-tube l3, and usually the lamp will stand 011 a suitable base. a portion of which is shown at O. The perforated deflector E at the up er end of the air-tube B is of ordinary character.

The wick F surrounds the air-tube B and is within the wick-raising band G, which has teeth 2 to enter the wick. The band G is of sheet metal, and it is rendered elastic by vertical corrugations. The object of these corrugations is to adapt the band to wicks of different thicknesses and to obtain a nearlyuniform friction of the wick on the air-tube to prevent the former slipping down by any jar or concussion of the lamp or its support. The lower end of the wick is preferably cut longitudinally, so as to allow of a greater length being introduced than could be inserted if cylindrical throughout.

At one side of the wick-raiser G is a loop 4, through which passes the upwardly-projecting end 5 of the wick-raising rod H, which goes up through an opening in the top of the reservoir and terminates as a knob or lifter. The end 5 is made with a mortise above the loop 4 for the reception of a spring cross-key 6, that serves to connect the parts. By the withdrawal of such key the band G is separated from the rod H to allow the wick and its hand to be lifted out of the lamp or replaced by a reverse operation.

The wick-tube K is cylindrical, with nearly parallel sides at its upper end to surround the wick F, and its lower part is flaring or hellshaped. The base 8 of such tube rests upon the top of the reservoir and within the annular rib 13. The tube K is provided with tongues 10, passing through mortises in the top of the reservoir. By this construction of the wick-tube the wick is kept cool, and vapors arising from the reservoir are directed to the wick and pass up to the flame, and should there be any oil upon the outside or inside of the wick-tube K it will pass back into the reservoir.

The chimneyrest L is at the top of the perforated air-distributer N, which is contracted to form a groove 9 to set closely around the flaring portion of the wick-tube K. The cylindrical bottom end of the removable air-distributor and chimney-holder is slotted at 22 to form with the pins 20 on the circular ledge 11 11 of the reservoir a look similar to a bayonet-lock to hold both the chimney-holder and the wicktube firmly to place, thus giving great facility for connecting and disconnect ing the parts for lighting, trimming, cleaning, or introducing a fresh wick.

I claim as my invention- 1. The combination, in an Argand lamp, with the reservoir and central air-tube passing through the reservoir, of a wick-tube setting closely around the wick at its upper end and having a flaring lower end to rest upon the top of the reservoir and close the opening therein, and a separate chimney-holder re movably connected to the reservoir and surrounding and confining the lower end of the wick-tube in place, substantially as set forth.

2. The combination, with the reservoir and central air-tube in an Argand lamp, of a nicktube having an upper end setting closely around the upper end of the Wick and a lower end flaring outwardly, a chimney-holder and air-distributer surrounding the Wick-tube and contracted to form an annular groove setting closely over the flaring port-ion of the wicktube to confine the same in place, and a looking device to connect the base of the removable chimney-holder and air-distributer to the reservoir, substantially as set forth.

3. The combination, with the reservoir and Argand burner, having a central air-tube upon which the cylindrical wick is raised and lowered, of an endless band of sheet metal surrounding the wick and having Vertical c0rru gations to render it elastic for applying to the wick the friction necessary to hold the samein any position to which it may be moved upon such air-tube, and a lifter connected to 2c the elastic band, substantially as specified.

Signed by me this 29th day of April, 1890.

JAMES H. \VI-IITE.
