GAS-SSTOVE.

SPECIFICATION forming part of Letters Patent No. 427,129, dated May 6, 1890.

Application filed May 20, 1889. Serial No. 311,460. (No model.)

T0 aZZ whom it may concern:

l $e 1t known that I, SAMUEL STEWART, a citizen of the United States, residing at Newark, Essex county, New Jersey, have invented certain new andusefulImprovements in Gas- Stoves, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is 'to furnish by a cheap and efficient construction a gas stove in which the burners are Wholly exposed to the surrounding atmosphere and are thus adapted to radiate freely, while the amount of metal in contact with the body of the burners is made exceedingly small, so as to absorb and radiate as little heat as possible. The entire apparatus is thus adapted t2) 1use where the radiated heat is objectiona e.

The invention also consists in a particular construction for the burners whereby the flame may be brought into closer contact with the top of the stove and with the articles resting thereon when required.

In the drawings, Figure 1 is a side elevation of the stove; Fig. 2, a plan of the same. Fig. 3 is a sectional plan of the burner-grat- 1ng on line y y in Fig. 1; Fig. 4, a section of the same on line xx in Fig. 3; and Figs. 5 and 6, avertical section, upon a larger scale, of one of the burners in two different positions.

a is the top of the stove. provided with holes b, over which the articles to be heated are set.

(Z are legs extended from the corners of the top, and e is a grating affixed between the legs below the top to support the burners f and the feeding-pipe g.

The gratings, as shown in Figs. 2 and 3, are formed as a skeleton casting of light bars connected to rings e", through which the burners are inserted. A similar grating e is affixed to the legs, of a higher level, with the upper parts of the burners passed through the rings 6, which are thus steadied thereby.

The pipe g is shown provided with branches Z extended transversely beneath each of the burners and affixed to the grating c by ears '6, each branch being provided with a cock j to shut the gas from each burner separately. The pipe supports the weight of the burner,

which consists in a bottom thimble if, having the sleeve f fitted to slide upon the same and provided at the top with netting f.

The thinlble t, as shown inFig. 5, is provided with holest atits opposite sides, through which the pipe Zis inserted, as shown in Fig. 6. The sleeve f is provided with slots f at the bottom upon opposite sides, as shown in Figs. 5 and 6, and is thus adapted to set down over the pipe 1, as indicated in the two burners at the left side of Fig. 1. The sleeve is also adapted to be lifted to bring the netting f closer to the top a, as shown at the right side of Fig. 1, and as the flame is located upon the netting by the mingling of the air and gas beneath the same such elevation of the sleeve obviously brings the flame closer to the articles placed upon the stove-top. The sleeve may be sustained by friction upon the thimble t when thus lifted, or it may be turned at right angles to its lowest position, as shown in Figs. 5 and 6, and the lower end of the sleeve may thus rest upon the pipe to hold it positively at such elevation. By turning the sleeve until the slots fall over the pipe the sleeve may be lowered, as shown at the left side of Fig. 1.

It will be seen that the gratings e a contain very little metal and are thus not adapted to absorb and radiate heat, while the interspaces 5 between the different bars of the grating permit a very free circulation of air around the gratings and burners and thus operate to rapidly diffuse the heat and prevent any portion of the stove from acquiring a high temperature.

The stove is thus adapted for use in apartments where radiated heat is objectionable, While the adj ustability of the burnersleeves f enables the operator to adjust the flame to or from the article to be heated, and to thus economize the consumption of the gas and the utilization of the heat in the most effective manner.

It will also be seen that the burners are exceedingly simple and cheap, consisting merely in the open-bottom tubes into which the air enters freely to mingle with the gas which escapes from one or more apertures Z formed in the pipes Z within the thimble t.

The nettings f are commonly used for such gas-burners; but any form of perforated metal or suitable material may be employed in practicing my invention.

I am aware that it is notnew to construct a lamp-stove with a burner supported by means of the supply-pipe therefor, as in United States Patent No. 329,598, dated November 3, 1885, and that it is not new to provide a casing inclosing the burner to serve as an air-guide to direct the heated air against the bottom of the vessel to be heated, such casing having an adjustable sleeve at its upper end, as in United States Patent No. 248,611, dated October 25, 1881, and No. 254,052, dated February 21, 1882. I hereby disclaim theabove patents, limiting myself to the specific construction claimed herein.

7 Having thus set forth myinvention, What I claim herein is 1. The gas-stove consisting in the top a, legs cl, and skeleton gratings e. e sustained between the legs at different heights, with rings 6' to admit tubular burners, pipes Z, fixed beneath the grating e transverse to the rings, thimbles t, afiixed upon the pipes, as described, and the sleeves f, provided with nettings f, and movable vertically upon the thimbles for adjusting the flame to and from the top of the stove Without affecting its size, substantially as shown and described.

2. The gas-stove consisting in the top a, legs d, and skeleton gratings 6 e sustained between the legs at dilferent heights, with rings 6' to admit tubular burners, pipes Z, fixed beneath the grating e transverse to the rings, thimbles t, atfixed upon the pipes, as described, and the movable sleeves f, provided with opposite slots f in their lower ends, and provided with netting f, and adj ustable vertically upon the sleeves, substantially as herein set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

SAMUEL STEWART.
