v Application filed may 23,

My invention relates toimprovements in heaters, and more particularly has reference Fig. 2 is a cross-section on Fig. 1, and Fig.

3 is a section on the line-8-3 of Fig. 2 looking from left to right thereat. I a

4 indicates the base or table of the heater, and 5 a suitable channel or recess in which the radiant or blocks of refractory material are removably mounted. 6 indicates a removable. channel for the support of the grilles adapted to stand in front of the radiants, and said channel is preferably provided with key-shaped end portions such as 7 adapted toseat within the recess 8 at opposite ends of the table as shown. Between and substantially below the channels 5, 6 are the burner chambers 9 provided with substantially triangular mixing chambers as shown and grids 10 through which the mixture passes to be burnt. 11 indicates the Bunsen burner tuberonnected to said burner chamber and preferably terminates with. a flareend 11 adaptedto be seated inthe bifurcated or V- shaped .member 12' shown to advantage in Fig. 3, a stop"men1ber13 being provided to engage the periphery of the enlarged end 11 for insuring proper positioning ofthe burner. At the opposite side of the table prongs or lugs 14 extend and are provided with seatingssuch as 15 or depressions between the enlarged portions 16, 17 andthe burner is preferably beveled or rounded as indicated at 18 to engage the seating .15

and is also preferably provided with teats.

or buttons 19 adapted to bear against the front surface 20 of the channel 5 to further insure the proper positioning of the burner, from all of which it will be seen that the burner may be placed in position as shown without disturbing any parts except the hearth plate or shelf 21 which may then be placed in position, the depending flange 22 thereof having cut-away portions such as 23 to clear the Bunsen tube 10 of the burners, said flange 22 serving as a wind guard. The lugs such as 24L project upwardly from the casting or table 4 at op- HEATER.

posite sides and engage the ends of the hearth shelf to keep the same from shifting from side to side while the lug 25 extending from the under frame of the hearth table 21 engages the inner surface of the manifold or rectangular gas channel 26, thereby preventing the hearth table from movingfout from the heater. This hearth table consists preferably of a frame such as 21 provided with such as 28 of 'tileor other suitable material which may be sealed with cement such as 29 or other suitable hermetical binder.

From the foregoing it will be obvious that the shelf or hearth 21 may be conveniently removed, likewise the channel 6 after the grilles have been taken away, and alsothe spuds 30 which are adapted to be screwed in the gas. channel 26'as shown to advantage in Fig. 2. u

The grids 10 it will be observed are beveled along the longitudinal sides so that they may be slid into and out of the open mouth at the top of the burner head 9, and when in position may be locked therein by V transverse connecting members orstraps 27 upon which may be secured slabs pinching. the ends of the walls 31 of the burner niouth as shown. These grids may of course be secured 111 other ways such asby a pin, and grids with openings of different 'newablein parts, convenient for shipment and simple for manufacture.

Of course it will be understood that vari ous modifications may be made in theconstruction and arrangement of parts without departing from the spirit of the invention as claimed.

I claim:

1. In a heater of the class described, a base section having a removable hearth, a removable grille holder back of the same, and re movable burnersbeneath said hearth.

2. In a heater of the class described, a hearth section having a removable shelf, a removable grille holder back of the same,

and removable burners beneath said shelf, and in combination therewith positioning means for insuring the proper location of each of said burners.

3.
