PORTABLE H EATER.

SPECIFICATION forming part of Letters Patent No. 469,417, dated February. 23, 1892.

Application filed November 11, 1890- Serial No. 371,018. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM F. FALLS, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and use ful Portable I-Ieater, of which the following,

- taken in connection with the accompanying drawings, is a specification.

My invention relates to portable heaters for warming rooms; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the drawings and to the claim hereinafter given, in which my invention is clearly pointed out.

Figure 1 of the drawings is a side elevation of my portable heater arranged to utilize the flame of an oil-lamp. Fig. 2 is a vertical section of the heater-drum on line 0000 of Fig. 1, and Fig. 3 is an elevation of a similar heater applied to an Argand gas-burner.

In the drawings, A is the heater-drum,n1ade,

' preferably, of Russia iron, open at the bot tom and closed at the top-and provided with one or morepreferably twolaterally-projecting pipes B 13, located, preferably, about one-third of the length of the drum A from its upper end. The drum A is provided with an eye or book 0 in the center of its upper end, by means of which it is suspended on the arm aof a stand'D or other support above The drum A should be suspended over the lam p or gas-burner, so that the top of the chimney F of the lamp or burner is just within the lower end of the drum, as inclicated by the dotted line 2. (See Fig.1.) The arm a is adjustable vertically upon the vertical rod of the stand D, so as to'adjust the drum to lamps or chimneys of different heights. \Vhen it is desired to apply the heater-drum to a gas-burner, the arm a may be bentin the form of a crane and be screwed into a socket on the gas-pipe, as shown in Fig. 3.

By the use of this heater, in combination with an ordinary coaloil lamp or a gas-burner, a sufficient amount of heat will be evolved to keep a moderatelysized room at a combe comfortable without some artificial heat.

This heater-drum maybe used in combination with an ordinary gas-burner having no chimney, but in such case the heaterdrum should be, so adjusted that the flame from the burner will be just within the lower end of said drum, when a very good result will be obtained in respect to heating; but very little illuminating effect will be obtained from said flame, because it will be so largely shaded by the drum. The hot gases arising from the flame of the lamp or gas-burner rise to the top of the drum A, and the space above the horizontal pipes B B serves as a reverberating-chamber in which said hot gases are thoroughly intermingled with the oxygen of the air before beingdischarged therefrom to be distributed over the room, while at the same time the drum is heated to a high tem perature and gives off additional heat by radiation. The pipes B are made to project beyond the wall of the drum a sufficient distance to convey the heated air from the interior of the drum beyond the current of air heated by contact with the outer wall of the drum and which is constantly rising in near proximity to said drum, whereby the heated air discharged from said pipes is thrown farther into the room, and as a consequence the ot air is more evenly distributed over the room. Two horizontal pipes B are shown; but a greater or a less number may be used, if desired, with good effect.

The novel construction of the arms a and the manner of applying them to the standard D are to form the subject-matter of another application, and therefore are not claimed in this specification.

What I claim as new, and desire to secure by Letters Patent of the United States, is

In combination with an oil or gas. burner, a drum or cylinder having its lower end open and its upper end closed and having a plurality of horizontal discharge-pipes projecting therefrom at or near the middle of its height, suspended above the flame of the burner in position to serve as a reverberating-chambcr for the hot gases arising from said flame.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 10th day of November, A. D. 1890.

WILLIAM F. FALLS. \Vitnesses:

N. C. LOMBARD, WALTER E. LOMBARD.
