and the nozzle 10 lies with its stem 20 disposed in said slot. A collar 21 formed on said stem is adapted to lie above the plate 16 so that the plate 16 and the spring plates 12 and 13 are gripped between the collars 21 and 15 The resiliency of the plates 12 the nozzle in position. The nozzle can be removed by turning the plates 12 and 13 until the opening 18 is fully uncovered, at which time the stem of 7 the nozzle can be withdrawn from the slot "19 and then can be withdrawn from the mixing-chamber 2 through this opening 18.

This construction affords a ready means for assembling the nozzle and a simple arrangement for holding it firmly in place and for permitting its ready dismantlin 'or removal from the mixing chamber. The sleeve 11 may be suitably and artistically ornamented or arranged to hide the plain- V ness of the casting.

At the other end of the conduit 1 a large generous burner chamber 3 is provided, somewhat cup-shaped in form and having its'upper edge notched, as indicated at 22. A spreader plate 23 rests on the upper edge of the'burne'r chamber 3, and it is beneath .the edges of the spreader plate 23 and 'plate covering it permits the flame very simple matter I through the 28 and rests on a nut notches 22 that the flame escapes from the'burne-r chamber 3. The flame escapes from this chamber and heats a semispherical mantle 2 1 which is also provided with a hood 25 above it, in the 'manner described in my copending applica tion. This mantle is also provided with apertures 26 and 27 through which the heat and gases may escape beneath the hood. The mantle is mounted-on a threaded stem 29 disposed on said stem. This stein extends down through the burner chamber 3 and at its lower end is provided with a clamping nut 30, and is also provided with a nut 31 bearing against the spreader plate 23. This burner chamber is or" generous dimensions, and the spreader to be the mantle 2 1. It is a to dismantle this end. of the heater, since by merely unscrewing the spread out beneath nozzle in position,

nuts on the stem 28 it can be withdrawn from its relation with the burner chamber 3 and the entire device disassembled in this simple manner.

What I claim is 1. A gas heater which includes a conduit to be disposed in a horizontal position, a dependent mixing chamber extending downwardly therefrom having a plate across the bottom thereof and having sector-shaped openings in said bottom plate, a sleeve surrounding said mixing chamber, inwardly extending sector-shaped spring plates on the lower end of said sleeve, and a nozzle ex tending into said mixing chamber and enaged by the inner ends of said spring plates to hold the nozzle in position. i

2. A gas heater which includes a horizontally disposed conduit, a dependent mixing chamber-at one end thereof having an apertured plate across its bottom, said plate having a slot-formed in its central portion, said slot extending inwardly from the edge of one of said apertures, a gas nozzle to be disposed in said slot, and a pair of collars on said nozzle disposed on opposite sides of said plate to support the nozzle on said plate. 7

3. A gas heater which includes a horizontally disposed conduit, a dependent mixing chamber at one end thereof having an apertured plate across its bottom, said plate having a slot formed in its central portion, said slot extending inwardly from the edge of one of said apertures, a gas nozzle to be disposed in said slot, a pair of collars on said nozzle disposed on opposite sides of said plateto support the nozzle on said plate, and a sleeve surrounding said chamber having inwardly extending spring plates disposed across the bottom of said chamber, the ends of said plates engaging between thelower collar on the nozzle and the under surface of the plate to resiliently hold the nozzle in position.

4. A gas heater which includes a horizontally disposed conduit, a dependent mixing chamber at one end thereof having an 'apertured plate'across its bottom, said plate having a slot formed in its central portion, said slot extending inwardly from the edge of one of said apertures, a gas nozzle to be disposed in said slot, a pair of collars on said nozzle disposed on opposite sides of said plate to support the nozzle on said plate,

and a sleeve surrounding saidchamber having inwardly extending spring plates disposed across the bottom of said chamber,

the ends of said plates engaging between the lower collar on the nozzle and the under surface of the plate to resiliently hold the said spring plates acting as means to adjustably regulate the amount of the apertures exposed to regulate the flow of gas.
