' NITED STATES JOSEPH DE BONDINI AND ALBRECHT SEEFELDEB, OF CONSTANTINOPLE, TURKEY.

WlCK-HOLDING ATTACHMENT FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 365,973, dated July 5, 1887.

Application filed November 10, 1886.

To all whom it may concern.-

Be it known that we, JosnrH DE BONDINI, a subject of the King of Italy, and ALBRECHT SEEFELDER, a subject of the Emperor of Austria, both residents of Constantinople, Turkey, haveinvented anew and useful lmprovementin LampWVicks or Burner-Tips, ofwhich the following is a specification.

The irregular burning of lamps using petroleum or other oils, the flickering of the light, the bad odor which is given out, and the frequent breaking of chimneys are caused largely, if not principally, by defects in the wicks of such lamps. The trimming of the wick is apt to be uneven unless great care is used. There is also an inerustation or 'carbonization of the wick, which impairs the steadiness and brilliancy of the flame, and in trimming the wick carbonized particles fall into the interior of the burner, where they are apt to obstruct the passage of air to the flame and to give out an unpleasant odor. To overcome these objections, it has been proposed by several inventors to provide burner-tips of asbestus or other incombnstible materials, such tips being arranged in contact with the top of the usual wick or other absorbent material, which is used solely for the purpose of drawing up the oil to v the burner-tip. Such asbestus-tipped wicks have usually been inclosed in a tube and the flame adjusted by raising or lowering said tube, or by raising or lowering another tube around it. So far as we are aware such incombustiblc tips have not proved very satisfactory in actual use, since the mineral substances of which they have been formed are not suflieiently absorbent of the oil, and their pores are liable in time to become clogged or choked Serial No. 218,500.

or Argand burner. Fig. 2 is a similarview of a tip for a flat burner. Fig. 3 is a perspective View of the retaini ng-cap for an Argand burner, and Fig. 4 is such a view of the cap for a flat burner. Fig. 5shows in perspective an Argand bu rncr provided with our invention, and Fig. 6 shows a flat burner so provided. Fig. 7 is a vertical mid-section of an Argand burner, and Fig. 8 a similar section of a 'flat burner provided with our invention.

Let A designate the usual burner, either flat or round; and B, the usual wick. In the case of a flat burner theavick is held and guided in a flat wick-tube, d, as usual. In the case of an Argand burner the wick is held between an outer tube, (1, and an inner tube, 0, as usual. In fact, our invention involves no change in the existing construction of ordinary or common'lamps to which it is to be applied.

The burner-tip a, two forms of which are shown detached in Figs. 1 and 2, is formed of papiermaeh, which is made porous or unsized, so as to be capable of absorbing the oil, and is molded of the same shape as the wick to which itis to be applied. For an Argand wick it is made in the shape of a ring, and for a flat Wick it has the form of a straight bar. In either case its thickness should be the same as that of the wick, and it should have a height of four or five millimeters by preference.

The burner-tip, when placed on the wick;

should touch it at all points, in order that itv may absorb the oil from the wick readily and uniformly. To insure this the wick should be trimmed to a uniform level, so that its top shall conform to the under side of the burnertip. The burner-tip is then placed on the wick and held in place thereon by any suitable retaining device that will keep it pressed into close contact therewith without interfermeans that we have devised for this purpose consist of a ring, I), of sufficient weight, carrying fingers c c, the pointed ends of which are bent over, as shown in Figs. 3 and 4, so that when placed on the burner these points or hooks rest upon the top of the burner-tip, as shown in Figs. 5 to 8. The ring I) is of any shape-circular, conical, or rectangular-according to the shape of the burner with which it is to be used, and is large enough to pass' easily over the wick-tube d. The points or hooks c c are arranged atintervals all around the burner-tip, so that thelatter cannot escape from them. The ring I) is of metal, having sufficient weightto keep the burner-tip pressed closely against the wick. As the wick is adjusted up or down to regulate the flame, the burner-tip moves up or down with it.

The retaining device shown may be replaced by any other equivalent device which will'exert aslight downward tension or pull upon the burner-tip sufficient to hold it in contact with the wick and permit of the adjustment thereof. The tension should be sufficient, that when the wick is lowered the burner-tip will be drawn down with it until its top is flush with the top of the wick-tube, and it should not be so great that when the wick is raised the burner-tip will resist its ascent.

In the use of our invention the burner-tip is simply placed on the wick and the retaining-ringbis dropped overit. When the burnertip becomes inorusted or otherwise needs renewing, it is taken off and thrown away and a new one put on in its place, which is. the work of an instant. burner-tip may be done every day, or at less frequent intervals. The burner-tips will be manufactured in standard sizes and sold in This renewal of the boxes, and being very cheap their use will be both convenient and economical. There is no trimming of the wick, and hence no spoiling of it by irregular cutting. The lamp burns with greater brilliancy and steadiness, and there is much less liability of breaking the chimney. There are, furthermore, no carbonized particles which fall into the burner, and hence no bad odor is given out.

We claim as our invention- 1. In an oil-lamp, the combination,with the wick-tube and wick, of a burner-tip of absorbent material placed on the wick, and a retaining device independent of the wick-tube engaging the burner-tip and constructed to exert a downward tension thereon, whereby the tip is held in contact with the wick without interfering with the vertical adjustment of the latter, substantially as set forth.

2. In an oil-lamp, the combination, with the wick-tube and wick, of an absorbent burnertip placed on the wick, and a retaining device consisting of a ring constructed to pass over the wick-tube, and a series of hooks carried by said ring and engaging the burner-tip, whereby the weight of the ring holds the burnertip against the top of the wick, sub stantially as set forth.

3. A retaining device for burner-tips, consisting of. a ring, b, shaped to slip over the wick-tube of a lamp, and hooks c 0, extending upwardly from said ring and pointcdinward- 1y, substantially as set forth.

In witness whereof we have hereunto signed our names in the presence of two subscribing witnesses.
