BURNER FOR GAS STOVES.

$PECIFICATION forming part of Letters Patent No. 440,452, dated November 11, 1890. Application filed July 22, 1890. Serial No. 359,485. (No model.)

To all whom it may concern. 7

Be it known that I, HENRY O. WEISKITTEL, of the city of Baltimore and State of Maryland, have invented certain Improvementsin Burners for Gas-Stoves, of which the following is a specification.

In the description of the said invention which follows, reference is made to the accompanying drawings, forming a part hereof, and in which- Figure 1 is a longitudinal section of the improved burner; and Fig. 2 a cross-section of Fig. 1, taken on the dotted line 0: cc. Fig. 3 is a top view of the invention.

Referring to the said drawings, A is a pipe, formed for convenience in two parts or sections a and b, which are held together by means of two rivets c inserted through the lugs d and e on the upper and lower sections of the pipe. This pipe is secured in any suitable manner in the gas-stove, which is not shown in the drawings, as it forms no part of the present invention. The inner end of the pipe A is turned up and forms a nozzle B.

O is a circular plate, having a central hole D and an annular lipfaround it, which fits closely over the nozzle 13. The circular plate 0 is fitted with a peripheral rim g, within which is situated a ring E, of wire-gauze or perforated tin-plate.

F is a cap-plate, having an annular lip h on its under side, and it corresponds in size with the plate 0 and is placed over the perforated ring E. This cap-plate has a central hole 2', and around the hole is a raised projection 7t, within which is a second perforated ring II, of a similar character to the one E, except that it is smaller in diameter and of less height. This second perforated ringis surmounted by a cap-plate I with a lip Z, and the whole structure is tied together by a bolt K, which is passed through the upper cap-plate and also through a boss m on the under side of the pipe A, at which point it is provided with a thumb-nutn. The head of the bolt K is square and countersunk in the plate I, so as to not present any projection, and also to prevent its being turned inc'lependently of the capplate I.

In order that the wire-gauze rings E and H may be slightly stretched or forced out to their greatest diameters and against the rims g, h, is, and Z as the nut 11, is tightened on the bolt K, the opposing faces 0, p, q, and a" of the plates 0, F, and I are beveled toward the rims, as shown in Fig. 1. The said rims stand apart, so as to form the openings 8 and tfor the passage of flame.

Gas is introduced into the pipe A through the medium of a small pipe, (denoted by L,) and air passes in around the gas-pipe and combines with the gas, forming a combustible mixture, which enters the first gas-chamber M through the hole D and escapes through the perforated ring E, on the outside of which it is burned, forming a flame which extends upward in annular form. A portion of the gas, however, enters a second gas-chamber N through the hole 2', and, passing through the perforated ring ll, produces a second annular flame, of smaller diameter than the first and on a higher plane.

The joints between the several parts of the burner are made gas-tight by means of some suitable cement. (Shown in Figs. 1 and 2 and denoted by a.)

I claim as my invention- In a gas-burner for a gas-stove, the plates 0, F, and I, having the beveled faces 0, p, q, and r and the peripheral rims g, h, k, and Z, combined with the gauze rings E and H and the bolt K, substantially as and for the purpose specified.
