JAMES FRANK PLACE, OF MONTOLAIR, NEW JERSEY.
LAMP.
SPECIFICATION forming part of Letters Patent No. 392,822, dated November 13, 1888.
Application filed August 17, 1887. Serial No. 247,188. (No model.)
To aZZ whom it may concern.-
Be it known that 1, JAMES FRANK PLAoE, a citizen of the United States, and a resident of Montclair, in the county of Essex and State of New Jersey, haveinvented certain Improve ments in Burners for Liquid Hydrocarbons, of which the following is a specification.
My invention relates to that class of burners for lamps and the like which employ tubular wicks and which are adapted for burning liquid hydrocarbons; and the object of my invention is to provide for a more perfect combustion of the oil than is ordinarily attained in burners of this general character.
My invention will be fully described hereinafter, and its novel features carefully defined in the claims.
The drawing, which serves to illustrate my invention, is a sectional elevation of a lamp provided with my improvements.
A represents the body or oil-receptacle of an ordinary lamp, in which is mounted an annular wick-tube, K, adapted to receive an or dinary tubular wick, j. The air passes up through the hollow or bore of the wick-tube to supply the inside of the ring-like flame with air, a central draft-tube, D, being provided to lead all of the air thus supplied into a regenerative distributing-cap, D, which houses the upper end of the tube D. This cap D comprises a cap-plate, e, and a perforated side wall, f. I prefer to enlarge the cap D at the top, so as to extend out over the wick and to contract it below, as represented; but this is not absolutely essential. The tube D extends up into the cap nearly to the cap-plate e, and the upper portion, 1', of said tube (which may or may not form an integral part of said tube) is flared to correspond in contour with the flared portion of the side wall, f, of the cap. There is an annular'space or passage, t", between said wall f and the upper portion of tube D, which is housed in the cap. This de vice compels all the air supplied to the inside of the flame to pass up to the upper portion of the distributing-cap,and thence over the flared top of tube D, and downward again by way of the annular passage t", exterior to said tube, from which passage it passes out through the perforations in the wall f to the flame. The heated air is thus supplied uniformly to the flame-wall in fine and evenly-distributed jets. The outside of the flame is also supplied with air in a similar manner, all the air that reaches the exterior side of the flame being also heated and distributed to the flame.
B is an ordinary draft-chimney, made from glass or other similar transparent material. This chimney is mounted on asupport, g,which consists, as herein shown, of a folded plate, with the fold or bight turned upward. The two plies of this folded plate form two perforated ring-like walls or bands, which surround the upper end of the wick-tube, leaving an annular space, 9*, between them. All the air that reaches the flame from the outside must pass through the perforations of the outer band into the space 9*, and thence through the perforations in the inner band to the flame. As these bands 9 become hot, they heat the air on its passage inward, and they also distribute it evenly to the flame all around.
To further heat the air before it reaches the flame from outside, ,I employ an exterior chimney, O, of glass or other transparent material, said chimney surrounding at its lower part the perforated bands 9, at the base of which it is provided with a holder, 9. At its upper part this exterior chimney surrounds the lower part of the draft-chimney B, an annular passage, h, being left or formed between the two chimneys B and C and between the outer chimney and the bands 9, down which the air must pass to reach the perforations in said bands. The arrows in the figure indicate the courses of the air-currents on their way to the flame.
I am aware that it is not new to provide burners with double chimneys having an annular passage between them for the air to flow through on its way down to the flame, and that it is not new, broadly, to provide means for heating the air to be supplied to the flame of a burner. Therefore Ido not claim these features.
My burner is especially designed for illuminating purposes; but it may also be employed for heating.
Having thus described my invention, I
claim- 1. In a burner for liquid hydrocarbons, the combination, with an annular wick-tube, K, of an air-tube, D, arranged within said wick- IOO tube, through which all the air passes that is supplied to the inside of the flame, and a re generative distributing-eap, D, which houses the upper end of said air-tube and has a lateral enlargement at its top that extends out over the upper margin of the wick-tube, said cap comprising a cap-p1ate, e, and a perforated wall, 1'', the said tube D extending up into said cap nearly to plate a and provided with a flared extremity, substantially as shown.
2. In a burner foriiquid hydrocarbons, the combination, with the annular wick-tube K, of the two perforated bands 9, arranged exterior to and surrounding said wick-tube, inclosing between them an annular space, 9*, the
draft-chimney 13, mounted on the top of said bands 9, and the chimney G, arranged exterior to and surrounding the bands r and the lower part of the draft-chimney, said chimney 0 being of such size as to leave an annular airpassag'e, h, between it and the draft-chimney and bands, as set forth.
In witness whereof I have hereunto signed my namoin thepresence of two subscribing witnesses.
JAMES FRANK PLACE.
