IMPROVEMENT IN APPARATUS FOR BURNINGl PARAFFINE AND OTHER HYDROCARBON OILSl Specification forming part of Letters Patent No. 109,303, dated November 15, 1870.

To all whom it may concern Be it known that I, HENRY HARRISON DOTY, of London, iu the Kingdom of En gland, have invented new and useful Improvements in Means or Apparatus for Producing the more Complete Combustion of Paraine and other Hydrocarbon Oils; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon.

This invention relates to a lamp for producing the more complete combustion of paraffiue and other hydrocarbon oils; and consists in combining air-conducting cylinders with the wick-holder, and with a receptacle for oil, and brackets for the support of the chimney, rack, and pinions for operating the wick-holder and chimney-bracket.

Aseries of tubes or cylinders of dii'erent diameters, corresponding with the number of burners, are arranged vertically, one within the other, and uniformly brazed or soldered at the lower end to a plate or disk in such manner as to leave alternate air and cotton or wick spaces, the said air-spaces being continued through the plate or disk, and having a second series of movable tubes or cylinders passing through them, on the top of which are placed the flanged rings for projecting the air into the dame, the said cylinders and `flanges being raised and lowered by a screw and pinion, or any other well-known means. These said cylinders have ribs either on the outside or inside, (or both,) for dividing the air-spaces into equal parts, and the interior cylinders and flanged rings may be dispensed with when required.

A bracket for carrying the chimney, also raised and lowered by rack and pinion, encircles and may be fastened to the outer cylinder, so that both the bracket and cylinder may be raised and lowered together,`ifre quired, the said bracket having perforations for the admission of air to the outside of the flame.

The burners and disk are supported on columns, or otherwise, resting on a receptacle for containing-a supply of oil, the communication therefrom to the burners being through small tubes, some of which may contain the racks for raising and lowering the said burners.

The receptacle above mentioned communicates with a receiver by means ot' a copper or other tube, having a cock at its lowest part for emptying it of its contents when required, which said tube may be carried under the lenses of a light-house, (when used for that purpose,) so that H both the receiver and the air-tight reservoir, from which the receiver is supplied, may be placed outside the lenses.

The'said receiver is placed at a convenient height for the plentiful supply of oil to the burners, and is self-regulated by means of a cock in the air-tight reservoir, so that, as soon as the oil in the receiver reaches the mouth of the cock, the ow ceases, there being no pressure of air on the top of the liquid in the reservoir, to which the oil is fed by means of a suitable cock placed thereon.

In order that my invention may be clearly understood, I will describe the same with reference to the accompanying drawings, in which- Figure 1 is a section through the center of the lamp; Fig. 2, a plan of the said lamp; and Fig. 3, the general arrangement of the lamp, receiver, and reservoir.

va Vare the flanged rings for guiding the air to the flame, the said rings being supported on the cylinders b, which have ribs on one or both sides of them, for dividing the air-spaces c into equal parts, as shown in Fig. 1. d are the pinions, and e the racks for raising and lowering the Wick-holders f. g is the perforated bracket for carrying the chimney h, which is raised and lowered by the pinion i and rack 7c. l is the receptacle communicating with the wick-spaces by the tubes m.

In Fig. 3, n is the lamp; o, the copper or other tube communicating with the receiver p, which is supplied, by means of the cock q, from the receiver r.

Having now described the nature and particulars of my said invention, what I claim 1s- The herein described apparatus for burning hydrocarbon oils, consisting of the Wick- Done at London, England, this 27th day of holder f, cylinders b, receptacle Z, communi- July, 1868.
