IMPROVEMENT IN LAM PS.

Specification forming part of Letters Patent No. 40,222, dated October 13, 1.863.

'the body of a lamp. Fig. 2 is a diametrical section through Fig. l without the lamp-body. Y Fig. 3 is a top view of the lamp-cap, showing the corrugated cone on the same. Fig. tis

-a top view of the iiaring end of the wickvholding tube with the circular base ring secured in place. Fig. 5 is a perspective view Fig. 6 is an enlarged side view showing the chimney-holder and eccentric ring which carries the wickraiser. Fig. 7 is a diametrical section vshowing the top ofthe split wick-holding tube, and also the wick-raising spur.

Similar letters of reference indicate corre- 'sponding parts in the several figures.

My invention relates to that class of lamps intended for the use of coal or petroleum oils, and has for its objects the more complete combustion of the oil; the isolation of the heat produced to the burner and the obtaining of the advantages of what is known as a fountain-reservoir lamp77 at the same time; the ability to burn light-gravity oils, incident upon isolating the burner; the diminishing of tube from the flame; the reducing of the size ofthe opening into the oil-chamber for the purpose of saving brass, and improving the .one end with a male screw, a., by which to secure this end of the tube to a lamp-cap, a', as shown in Fig. 2. The opposite end or vertical portion ot' this tube has secured to it by a tight joint a tube, B, of a somewhat larger diameter, which forms an enlarged continuation of the tube A. This latter tube, B, being of a suitable length for receiving the wicktube and lamp-wick, its upper yend is split several times in a direction with-its length, forming the narrow strips b b b b, which, on being bent outward form the radial supports for the chimney, and give increased diameter to the tube B at a point surrounding the iiame. By this construction of the tube B a skeleton frame is formed, which receives atlat ring, b2, on theupper ends of the strips b, as'sh'own in Fig. 4, and this ring being properly secured to the strips b, itV serves as a brace for these strips, and also as a support for the chimney and cone; and by turning the projecting ends of these strips inward, as shown at c, Fig. 7,

they will form a part of the chimney-fastenving also.

The skeleton or open frame thus formed is surrounded by a jacket of beads, (represented in Figs. l, 2, and 6,) which may be of different colors. rlhis porous glass jacket (l will, when illuminated by the light contained within it, appear very pretty, and at the same time it will allow air to pass through it, and also form a neat and handsome cover for the strips b b b b. Instead of beads, the jacket may be made of any other material which will give the same result-such, for instance, as perforated, glazed, and colored paper, &c. the amount ot` heat conducted down the wick- 'The cone D, which is supported by or upon this fra-me, consists of a perforated conical body and a convex top having the usual opening, d, through it. The perforations through the side of cone D are made much larger th an common, and surrounding the cone covering the perforationsis a jacket, e, which may be made of glass beads or of any other suitable material. The convex top of'this cone is corrugated, as shown in Figs. l and 3, and the corrugations or waves run obliquel y to the flame or edges'of the opening d, and all run in the same lines. Now, it will be seen that by corrugating the cone top I bring into a very small compass a large amount of surface, and in this way I increase the amount of air impin gin g upon the flame. The ett'ect of making the corrugations in lines running obliquely to the flame is as follows: The ilame pressing into or toward these corrugations, its area and its combustion are increased, and as the air passes upward it is guided and directed by the oblique corrugations against the flame vertically in a converging direction, but laterally in one diverging, as shown by the course of the arrows in Fig. 3. The ame is in this manner spread outward, and its area is very much increased. Below the inverted conical frame formed by the ribs b b b b is a cylindrical box or plate, E, which is soldered fast to the tube B, as shown in Figs. 1, 2, 6, and 7. An opening is made in the circumference ot' this cylinder or box E for the reception of an eccentric, j', surrounding which is a ring or strap, g, to which a spur, g', is tlxed. The shaft or stem lz. of the eccentric f has its bearings in the portion E, and this stem projects out a short distance from this portion, and carries on its outer end a milled button, It. The spur g projects through a lrge hole, t', which is made through the tube B, and receives from the eccentric f. when its stem h is turned, a sliding and a vibratin g movement. This motion of the spur g is such as to cause it to thrust the wick upward a certain distance at each turn ot the stem h in ene direction, and to thrust the wick downward when the stem his turned reversely. The spur g is pointed on its thrusting end in order that it may penetrate the wick at each thrust, and to allow it to leave thc wick readily. I combine with this wick-adjusting device the spring-catch, which coniines the chimney (not shown in the drawings) down on the top of ring b2. This is done in the following manner: The thumb-piece 7c, by which the latch lis operated, is connected to the stem h in such a manner that it is allowed to slide back and forth on this stem 5 and between the thumbpiece k and the button h a spring, m, is interposed, as shown in Figs. 3 and 6, which by its recoil keeps the piece k up against the side of the portion E, or against a stop which may be formed ou the stem h. The latch l is secured atits lower end to the spring thumbpiece 7c, and its upper end is bent, forming a hook which projects through a stationary ear, n, toward the axis of the ring bz, as clearly shown in Figs. 3 and 6. The latch-rod l is curved inward, so that it will be out of the way; and the operation ot' this latch is as follows: To remove the chimney the thumb is placed against the button h', and with the index-finger the piece lc is pressed toward the thumb, thus drawing back the hook of the latch-rod Z, and allowing` the chimney to be removed from the burner. Within the enlarged tube B is a removable wick-tube, G, which I have shown in Fig.5 removed from the burner. This wick-tube consists of a slotted cylindrical portion, p, open at its lower end, and furnished on its upper end with a flattened portion, r, which is made up of a thin narrow strip of metal wound in a spiral form varound a rod-the edges of the metal strip overlapping each other-and soldered at suitable points to preserve the required form. The cylinder thus formed is soldered or otherwise secured to the upper end ofthe split tube p, and the upper end is now ilattened so as to form an oblong opening, rf, equal in length to the width of the wick. The object of a tube thus formed is, rst, to prevent to a great degree the heat of the flame from being conducted down the tube and volatilizing the oil therein too rapidly. The spiral strip performs this office, as the heat must pass round and round the tube portion r instead of straightdownits sides, hence the lower part of the tube will not get so hot as it would if it were made of one solid piece ot' metal in the usualma-nner'5r second, the tube being ilat at one end and round or cylindrical at the other, the flat wick s titting it assumes a similar form, and hence can be passed into the opening of an oil-chamber of a diameter which is less than the width of the wick, permitting thereby the use of a smaller opening in an oil-chamber, and allowing the wick-tube to be fitted into such a chamber without the interposition of a supportingcap or other such device.

rIhe wick-tube G is introduced into the wicktube holder B, and secured therein in such a manner that it may be removed at Tf pleasure. The lower end of this wick-tube extends down nearly, it' not quite, to the bottom of tube B, and at this point the wick J, which supplies the oil from reservoir K to the burner, terminates. The oil is supplied to the burner by the capillary attraction of the substance which is confined within the curved tube A, and it will thus be seen that theburner may be elevated above the level of the oil in the fountain-reservoir and still Mbe supplied with oil from this reservoir.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The manner of supplying a flame with oil at one side of a lamp bypcarrying the oil up through the top ot' a lamp and down over its side through a pipe or its equivalent, which is supplied with a wick," substantially as set forth.
