Application mea May as,

in the art upon a full 'understanding of the,l

construction, arrangement and operationot the improved heater.

One form of the invention is presented herein for the purpose of exemplification, but it will of course be appreciated that the invention is also susceptible of embodiment in other modiiied forms coming equally within the comprehensive scope of the appended claims.

In the accompanying drawing:

Y Fig. 1 is a plan view of the improved hea-ter; t

Fig. 2 is a vertical section through the heater,` taken on the line 2-2 of Fig. 1; and v Fig. 3 is a vertical section through the jet of the heater. f

` The heater illustrated in the drawingv includes a bowl 10, a ring 11, a cover 12, and a jet 13. The bowl 10 is upwardly dished, and is supported on legs 14 within the' lire boX. The jet 13 is positioned `concentrically within the bowl 10, and is in communica` tion with a supply pipe 15 which extends under and is suspended from Vthe bowl by brackets 16. The ring 11 is downwardly y 40 dished, and is supported above the bowl in spaced concentric relation to thelatter by brackets 17. The cover 12 is also downwardly dished, and is supported above the ring in spaced concentric relation to the latter .by brackets 18. The ring is of less diameter than the bowl, and the cover is of still less diameter than the ring.

The iet 13, which is located within the bowl beneathy both the ring and the cover,

consists oi a downwardly opening cylindrical cap 19 and an upwardly opening cylin-V drical cup l2O having a downwardly extending tubular portion 21. The cap 19 lits snugly over the c lindricall portiongof the ,55 cup 2()A The tubu ar portion 21` of the cup extends through a central. aperture 22 in lean. swarm. 193,431. v

.the bowl -1'(`).,and terminatesl just abovel an f upwardly 'directedwnozzle 23 fin the pipe 15, the top ofthe nozzlel andthe adjacent end oi the bore in the tubular portion 21 of the cup ybeing tapered as shown to provide ample .space or air to enter the.l jet betweenthe vsame,`land thcpnozzle being vertically adjustable` relative tothe pipe `by reason'o'i the threaded engagement therewith.

The tubular portion21 ofthe cup may also be apertured at 211to permitevenmore air to enter thonet. Y,The cap -19l is provided adgacent its upper edge with a large num- Aber of laterallyopening ports 25 and a large number ont' upwardly opening ports 26, which permit the gas to leave the jet, and the bowl 10 is provided with a few openings 27, which permit still more air to `'mix with the burning gasesbetween the bowl and the 'ring and the cover, and also prevent 'back-firin g.

rlhe construction of the jet 13, and the proportioning, spacing and shaping of the bowl, ring and cover, together produce a gas burning unit of great elliciency.r The gas entering the heater through the pipe 15 and nozzle V23 is directed laterally and t upwardly by the ports 25 and 26 in the jet 13 and ignites within thespace enclosed by the Ibowl, ring and cover, the flames shooting` laterally and upwardly through the annular openings between the bowl and the ring `and between the ring and the cover, in a large lcircular mass. kThe control of the burning gases effected by the bafflelike arrangement presented by the parts ol the heater assures rthorough Combustion of the gas and widespread distribution of the heat obtainedirom the same.

The heatermay be easily taken apart for cleaning or shipping, the cover merely resting` on the brackets 18 mounted onr the ring, and the ring merely resting on the brackets 17 mounted on the bowl. The jet 13 may be removed from the bowl by lifting the tubular portion 21 of the cup 2O of the j et up through the aperture 22 in the bowl.A

I claim v 1. ln a 4gas burning heater, an upwardly dished bowl, a downwardly dished ring spaced above the bowl, a downwardly dished cover spaced above the ring, and a jetpositioned within'the chamber formed Vbetween the bowl, ring and cover. y

2. In a gas burning heater,` a large 'bo-wl, a smaller vring spaced above the loewl Vring within the chamber formed between the bowl, ring and cover and provided with laterally and upwardly discharging ports.

4. In a gans burning` heater, a large np! wardly dished 'bowlprovided with air vents,

va smalier downwardly dished ring spaced above the bowl, a still smaller' downwardly vdish-ed cover spaced above the ring, anda jet positioned beneath the ring within the center ofthe upwardly converginlgchamber formed` between 1the bow'l, ring ,and cover "and fprovid'ed with laterally and upwardly discharging Orts.

' 5. In a vgas urning heater, av bowl, aring, Y

seats on the bowl for `supportingthe ring in spaced upwardly removable association with the bowl, a cover, seats on the ring for supporting ,the cover in spaced upwardly removable association with the ring, and a jet positionedl within the chamber 'formed betweenthe bowl, ring andcover.

6. In 4a gas "burning heater', a bowl, a ring spaced above the bowl, a cover spaced above the ring, a'ljet positioned within the'bowl and 'ha-ving a downwardly `extending tubular portion disposed within .anaperture in the bowl, and a supply pipe extending trans-,-

versely beneath. the bowl and having an upwardly opening nozzle lbeneath and in spaced vertical Valignment with fthe downwardly extending tubular portion of the et.

, In testimony whereof have here-unto subscribed my name.

PETER v. oLEsEN.
