JOHN COOK, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF HIS RIGHT TO G. L. SMITH, OF SAME PLACE.

IMPROVEMENT IN VAPOR-BURNERS.

Specification forming part of Letters Patent No. 120,627,dated November 7, 1871.

To all whom it may concern:

Be it known that I, JOHN COOK, of the city, county, and State of New York, have invented certain Improvements in Vapor-Burners, of which the following is a specification:

This invention relates to that class of burners used for the production of light from very volatile hydrocarbons; and consists in the combination and arrangement of various parts or devices as a supply-tube, provided with two lian ged disks near its upper end, and between which are holes to furnish carbon for heating them 5 also a slotted cap furnished with a screen of wire-gauze, all arranged relatively to each other, as hereafter described.

Figure l is an elevation of the burner-tip and anges. Fig. 2 is a bottom view of the upper flange, and shows the screen of wire-gauze in the tip. Fig. 3 is an elevation of the invention complete, with the step-valve all ready for connecting to the supply-tube. Fig. 4 is a vertical section of Fig. 3.

The supply'tube is connected at A, Figs. 3 and 4, the inner end of which is closed by the screw plunger or valve B, which is driven by a. key into the tube or against the end thereof, so as to stop any inward flow of the liquid toward the burner. Underneath said valve is a cup, O, for receiving alcohol or some similar substance, which, when ignited, will heat the burner to such a degree as to generate gas at the disks and tips sufficiently to start the operation in complete working condition. From the chamber, between the end of the tube A and the valve B when open, a small hole, D, leads upward to a transverse opening, E, where the liquid can come in contact with the burning alcohol in the disk C, and give an additional supply of fuel to the flame for heating the burner. Immediately above said hole or outlet vE the burner proper is attached, it being fully represented at Fig. 1 5 and consists simply of a tube, F, furnished near its upper end with two external disks, G and H, as shown in the drawing. To the upper disk H the slotted cap K may be attached 5 or it may be slipped on as a ferrule upon the upper end of the tube F, and thereby readily changed from a large to a small burner, and vice versa, as desired, without changin g the other parts. Through small holes at O O, between the disks C and H, the heated vapor escapes, and, taking fire from the flame below, quickly heats the Atube F and expands the vapor into an elastic gas by the time it reaches the cap K, when it will give a light equal to the choicest gas from coal. The under side of the external disk H is corrugated7 as shown at Figs. 1, 2, and 3, to extend the heating-surface and to produce points from which the soot will always be burnt,

so that the ilames from the jets O O will always come in contact with the metal disk H. In the cap or tip K is placed a screen of wire-gauze, M, which serves as a retarder or check-valve to the flow of the vaporized liquid, so as to give asteady flow, the amount being greatly due to the vari able sizes of the meshes in the gauze.

The vapor-burner, consisting of the tube F provided with disk G, corrugated disk H, holes O O, and slotted cap K having the wiregauze screen M, all arranged in relation to each other, substantially as shown and described.

JOHN COOK.
