JOHN H. IRWIN, OF CHICAGO, ILLINOIS.
IMPROVEMENT IN LAMPS.
Specification forming part of Letters Patent No. 65,230, dated May 28, 1867.
To all whom it may concern:
Be it known that I, JOHN H. IRWIN, of Ohieago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Lamps; and I do hereby declare and make known that the following is a full, clear,
and exact description of the same, reference being had to the accompanying drawings, and the figures and letters thereon marked, which form part of this specification.
My said invention relates to a novel mode of producing a draft or current of air at the burner of a lamp for the purpose of supplying oxygen thereto, and dispensing with the ordinary chimneys in common use for that purpose; and it consists in so constructing alamp that the heated air rising above the flame of the lamp shall cause a current of air to descend to apoint below the flame, and thence ascend to the flame, as desired.
To enable those skilled in the art to understand how to construct anduse my invention, I will proceed to describe the same with particularity, making reference in so doing to the aforesaid drawings, in which- Figure 1 represents a vertical central section of my invention. Fig. 2 represents the same constructed in chandelier form; and Fig. 3 illustrates a modified form of the same, the part in question being shown detached.
Similar letters of reference in the several figures denote the same parts of my invention.
A represents a lamp, surrounded with an inclosure, 13, leaving a space, a, between said lamp and inclosure, as shown, and having a burner of any ordinary construction. Above the burner is arranged a bell or funnel, G, from which rises and returns down to the lamp and enters the case B a pipe, D, as shown. When the lamp is ignited the heated air ascends in the pipe to the top, and then cooling, so as to become heavier, the said ascending current forces the cooler air down into the space a, (which need not extend below the point where the pipe D enters.) and up to the burner, as indicated by the arrows, thus producing a superior flame and one of great brilliancy.
When constructed as shown in Fig. 1, the
' mouth 0 of the tube should be arranged high enough above the flame to insure the entrance of fresh surrounding air to supply the flame with oxygen; but in Fig. 3, in which is shown a close heating-drum, F, within the pipe D, so that the air that has once passed up through the flame remains in the heater F, while fresh air is admitted through apertures c c, to pass around to the burner, as before described, is found a device which renders the distance at which the mouth 0 should be placed above the burner immaterial.
In Fig. 2 my invention is applied in chandelier form, R representing a central reservoir for oil, from which it is carried to the burners in suitable pipes, and the pipes D uniting and descendingin a central column, to be distributed at the bottom again to the several burners, substantially as shown in the drawings.
The pipe D may enter directly at the burner, or may enter the burner itself, so that it may readily be applied to any ordinary lamp.
Whenever the pipe D, returning downward to the lamp, is required to be short, a vessel or cup, E, to contain cold water to cool the air in the pipe D, may be arranged about said pipe, as shown, which may be filled through an opening, E, at the top.
To insure the desired result in my invention it is necessary that the tube D should be close, and have no apertures for the escape of the heated air therefrom, except at the'exit into the burner, as described, provided, however, that any small apertures that would not prevent the necessary current would form no objection. 7
Having described the nature, construction, and operation of my invention, I will proceed to specify what I claim and desire to secure by Letters Patent 1. In combination with a lamp or its burner, the tube D or its equivalent, arranged and operating substantially as and for the purposes specified.
2. In combination with said tube B, a cooler, E, arranged so as to operate substantially as described.
