'-'lMPROVE-IAVIENT' IN LAMP-BURNER-S.

The Schedule referred to ln these Letters :Patent and making part *of the same.

To ull-'whom it may concern:

Be it known that we, WALTER BnocTon JENNEY and GEORGE VASHIXGTON, TAYLOR, O` Fairhaven, in'the vcounty of Bristol and State of Massachusetts, have invented a new and improved Lamp-Burner and `we do hereby declare that the following is a full, clear,

` and exact description thereof, reference being had to the accompanying drawing iication, in which- .1

Figure 1 is a side view-of the improved burner. '-f Figure 2 is -a topview of the same.

making part of this speci- Figureis a diamctrical section through the burner.

Figure 4 isa diametrical section through the burner,

The nature of our invention consistsl First, in thecombination of air-directors anda lampburuer shell, which is very nearlyin the form of two paraboloids united together by au annular horizontal contracted portion, whereby the currents of air which enter the burner from below in a direction parallel to its vertical axis,and which impinge against its sides, will not onlybe directed inwardly and the heat whichy is radiated from that part of theliaine below thetop of the burner be reflected downwardly in parallel rays through the'air, but,'by the action of the directors,

. the draught is also increased and a larger perceutuin of oxygen is supplied to the flame, and the flame is caused to assume a flattened fish-tail form, all as will be hereinafter explained.

In. such a combination v'as above described,'it con i Siets- Second, in arranging the directors in reliefl from the wick-tube, as will be hereinafter described.

Thil-d, inthe application to a burner Of a gallery of spring lingers, which Arise from the flanged base oi= the burner and are so curved and .separated that while they afford, bytheir elasticity, a means for holding the chimney safely in place, they also serve as a means forv retarding the ascent of air between the chimney and burner, and thus prevent sudden draughts of air Vimpinging against the iiame above the burner, as will be hereinafter explained,

Fourth, it consists in the arrangement of the flanged shell upon the flanged perforated .diaphragm and un- ;der the springs, so that the shell and springs may' be readily removed without disturbing the diaphragm, as will be hereinafter described.

To enable others skilled in thc art to understand vour invention, we willf describe its construction and operation.

In the accompanying drawingl Arepresents the improved burner-shell,whiclris I showing the lower portion of a lchimney applied fo it.A

produced by thel well-known operation'of drawing a sheet of metal on a die.

The lower section oi' this burner-shell is of the form of the frustum of a parabola, havingv a auged base and an annular contracted portion, a, which is rounded, as shown in figs. 1,; 3, and 4, and which terminates in the concavo-eonvex slotted end b.

This portion a is also of a parabolic form, and its slot, o, through which the flame passes, has parallel l sides, as shown in iig. 2.

From the ends ofthe slot a two narrow strips, u n.,

incline inwardly or toward the'narrowedges ot' the wick-tube E, but do not touch this tube.` These pieces n n are,.prei`erably, soldered to the inside of the burner- Ashell, although they may be-made by bending down portions oi the shell which Vare cut in forming the slot o.

Surroundingthe burner-shell A is a chimney-holder, C, which consists of aeircular collar, p, and spring lingers c c.

This chimney-holder is contracted just above the collar p, so as to aiord a base-support for the chimney N, as shown in iig. 4, and also to allow a free inlet of air fthrough the passages c' c', as indicated by the arrows in g. 4.

The fingers are curved somewhat like the letter j; so that their 'upper convex sides will bear outwardly against the chimney N and hold it in place. 4These spring ingers c also operate to retard the ascent of air owing in at 'isutiiciently to prevent flickering from sudden draug'hts, but they do not prevent the proper supply of air tothe flame 'above the burner. These spring fingers 'c .extend up nearly to the annular contraction a of the burner-shell A and curve inwardly, thus forming an ornamental gallery around this shell. This chimney-holder G is secured permanently to the base-iiaiige of the burner-shell.

Within the burner-shell A is a perforated concavoconvex diaphragm, G, attached to a circular iiangc, h, which is held in place within the collar p by means of bayouet-astenings g. To this diaphragm the wick-tube E and screw-connectiond) are permanently fixed, as shown in the drawing.

The adj nsting-'spurs j are applied to the spindle J, and adapted for adjusting the wick inI the usual welllinown manner. v K The bayonct-fastcnings, which are used for connecting together the two sections constituting the burner, consist of L-shaped slots formed in the lange 7i' of the diaphragm,which receive studs or raised portions on the inner side of th collar p of the section C.

The advantages attending the peculiar form lof the ,burner-shell are, that the currents of air rising to the flame and impiuging on the sides of the lower portion of this shell will be directed toward the vertical center thereof, and7 th'ese mixing7 will impinge upon the broad sides of the ame and spread it in a direction with the Widest part of the wick-tube. The flame being inthe foci of the paraboloids, any heat radiated from 'that part of it which is below the top of the burner .the dame will present'the sh-tail form.

- The effect of the directors n n is to'prevent cold currents of air from impinging against the narrowestl sideof the flame; also to cause a contraction of the air currents passing through the burner above the level of the wick-tube and below the upper end of this burner; also, to cause a large lpereenturn of air to pass up on opposite sides of the broadest sides of the flame, and thus compress and spread the llame;

We do not claim a lamp-burner cone; nor do we claim a cap with straight sides anda reduced rounded tip; nor do we claiml deflectors having' closed sides; nor do we claim retaining a lamp-chimney-in position by means of springs but WVhat we do claim as our invention secure by Letters latent, is-

L'The defleetors n n., applied on the inside of the shell at the base of the slot o, and arranged in relief from the wickftube, in combination with the air-space between the ring h and the collar D, substantially in vthe manner shown and described. 1

2. The combination of the specified` deflectors n n with the shell A a b o, such shell being ot' the form herein described.

3. The device O, constructed with a collar, p5 curved spring'iingers c c, and air-passages i, in combination with the ring 71, shell A a b aand the chimney N. all in the manner and for the purpose described.

4. The chimney-holding and retaining device G, with the spring fingers c formed on it in such manner that the base of the slots between Ythe fingers forms air-passages, both inside and outside of the lampchimney, when such chimney is placed around the bumensubstantially as described.

5. The arrangement of the flanged shell upon the flanged diaphragm G and under the springs e, substantially inthe manner. described, so that the shell may be. readily detached when necessary.
