IMPROVEMENT IN LAMP-BURNERS.

Specification formin g parh of Letters Patent N0. 171,638, dated Deeember 28, 1875; application filed August 9, 1875.

T0 all whom z't may cmwern:

Be it known that I, FREEMAN A. TABER', 0f Boston, Suffolk county, Massachusetts; h2we invented certain Improvements in Lamp-Burners, of which the following is a speeification 'lhe drawing aeeompanying this speeificati0n represents a wertical section of a larnpburner containing my improvemencs.

In this drawing the base of the burner, which screws into t'he mouth of the 1amp, is shown at A, and the wick-tube, which is secu1ed t0 such base, is shown a4; B, bhe starwheel f0r elevating the wick being shown ab O. 'Ihe chimney-rest, which is suppoxted in pa1t by the upper port-i0n 0f the wick-tube, and in part by be ba.se A, is eomposed 0f an inner verticul tube 01. sleeve F, joined a1: er near its bottom 130 a horizontal perforated shell, a, which terminates in an upright annu- 1ar Wall, G, while the conieal air defleetor, which srrounds the upper portion 0f the sleeve F, and finde a upport; within the wall G, is showu at H.

'Il1e above description embraces the coustruction 0f lamp-burners now gener'ally in use. In earrying 01113 my irwention, 1:ue purpose of which is, mainly, to enable heavy hydrocarbon oils t0 be burned without smoke with a single wick-tube, I extend the sides of tl1e sleeve 01 tube F a short distance above the top 0f the wick-tube, leaving notches or depressions 0 c zu: ea;ch end, t0 permit of expansion er spreadiug of the flame. I then pierce the lower end 0f the sleeve F with a series of air-inlet ports, d d, &c. to per'mit of ingress of oxygen to aid in supporting perfect combustion 0f the oil ab the top of the wicktube.

I have found in praetical use 0f a burner 0nstructed a-s explainedthat is, With the slee"e F extending above the wick-tube, und. in connectsion therewibh the employment of the air-inlets dthat I obtain the following results: Firstinerustation of the top of the wick is very greatly retarded-a matter whieh has been very difficult to aceomplish in the buming of heavy hydrocarbon ojls, a product 0f petroleum now exteusively i1'1use; second, by inclosing two wieks side by side (er a single wick folded) in thewick-tubewhiehIoperate together by the wheel O, I obtain the same effeet es is produeed by the employment of two wicks in separate tubes placed im1nedi- .acely contiguous 130 each other, thus avoiding duplex gearing, and liability 130 disarrangemeut consequent upon the use of two tubes.

1. In a lamp-burner, the combination, with a slotted defleetor and a flat wick-tube, 0f a sleeve whose sides extend a short distance above thewicktube end whose ende ab the top are notched 130 permit expansion 0r spread of.the flamme, substantially as set foxth.

2. The sleeve F, provided with air-admitting perforations, and having its sides extended a short distance above the wiek-tube, in combi-- nation with the flat wiek-tube zmd slotted defleetor of a1 lamp-burner, substaufially as sei: forth.
