HYDROCARBON INCANDESCENT LAMP.

SPECIFICATION forming part of Letters Patent No. 642,942, dated February 6, 1900.

Application filed August 91 1899- To ctlZ whom it may concern.-

Be it known that 1, CHARLES E. WHITE, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hydrocarbon Incandescent Lamps,of which the following is a specification.

The objects of the invention are to provide a comparatively simple, efticient, and inexpensive hydrocarbon-lamp for heating WVelsbach and other mantles; to simplify, improve, and render more efficient the means by which the customary jet of oil is created, and to provide for the convenient removal of the depositions of carbon which are likely to occur in all lamps of the type to which the invention relates.

My invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which- Figure 1 is a view, partly in side elevation, illustrating a hydrocarbon-lamp embodying features of my invention. Fig. 2 is a View drawn to an enlarged scale and illustrating in central section details of construction embodying features of my invention. Fig. 3 is a transverse sectional view taken on the line 3 3 of Fig. 2. Fig. 4 is a top or plan view showing certain of the parts referred to in Fig. 2 and hereinafter described, and Figs. 5 and 6 are respectively views drawn to an enlarged scale and showing in transverse section and in plane the removable gas-check.

In the drawings, 1 is an oil fount or reservoir, from which oil is supplied past the valve 2 and through the oil-pipe 3, in which it is vaporized, and from thence the vapor is discharged into the mixing-tube 4, which receives at its upper end a supply of air, and the resulting mixture of air and vapor is supplied to and consumed at the burner 5. Between the oil-supply pipe 3 and the mixing-tube 4 there is a coupling. (Shown in Fig. 2.) Upon the upper end of the pipe 4 is mounted a spider 6, which is provided with openings 7, Fig. 3, for the ingress of air and with abridgepiece 8 for attachment to a nut 9. This nut Serial No. 726,650. (No model.)

9 is internally provided with a chamber, and the orifice at its lower end is somewhat contracted, so as to provide a shoulder or inwardly-extending flange. This flange supports the gas-check 10. The latter is removable and consists of a sheet of comparatively thin metal through which a hole is punched. The side walls of this hole are of somewhatconical form and project toward the pipe 4. Such a plate is readily made and is comparatively inexpensive,and it may be conveniently removed and freed from carbon and the like, which in the use of the device accumulates upon it, or, if necessary, the check may be readily removed and replaced by a new one. By the provision of checks having apertures therein of different sizes it is possible to employ one which gives the best results under varying conditions, such as are encountered in the construction of different types and styles of lamps. The tubular member 11 is fitted within the nut 9, and its upper end is pressed by the pipe 3 and its lower end serves to hold the gas-check in place. The upper end of this tubular member 11 is provided with a cap 12, of which the vertical walls are perforated comparatively near to the top of the cap and as at 13. The advantage of this construction is that the impurities by falling into the space 14 do not reach the interior of the cap and do not clog or interfere with the opening or openings in the check.

In use oil is vaporized in the pipe 3, the impurities collect in the space 14, and the vapor escapes by the openings 13 into the interior of the member 11, from which it is discharged through the gas-check 10 in the form of a jet. Air entering at '7 mingles with the vapor of this jet, and the mixture is carried along through the pipe 4 and consumed at the burner 5.

Among the many advantages of the described construction attention may be directed to the following: All lamps of the type to which the present invention relates are subject to being clogged by depositions of carbon. However, by reason of the described improvements the parts most subjected to this can be readily removed and cleaned or replaced by others. For example, the nut 9 may be unscrewed from the pipe 3, whereupon the member 11, as well as the gas-check 10, may be removed and cleaned. If neces sary, they may be replaced by new parts.

It would be obvious to those skilled in the art to which my invention appertains that modifications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts herein set forth and shown in the drawings; but,

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

1. A coupling for connecting the oil-pipe and mixing-tube of a hydrocarbon-lamp, which comprises the combination of a spider depending from a tubular nut having its internal chamber inwardly flanged at its lower end, a metal plate provided with a perforation and removablysupported on said flange, and a tubular member located above said plate and in the chamber of the nut and provided at its upper end with a cap having its curved side walls perforated near its top, substantially as described.

2. The combination in a hydrocarbon-lamp of a coupling provided Withatubular chamber having inwardly-flanged walls, a removable gas-check supported by said walls and a tubular member mounted in said chamber and superposed on said check and provided with an upwardly-extending cap of which the side walls are perforated near its top, substantially as described.

In testimony whereof I have hereunto signed my name.

CHARLES E. VVI'IITE.
