- the incinerator, in such manner that the entire mass is not only heated but burned throughout at practically the same time.

The drawings disclose in Figure 1 a garbage incinerator embodying my invention wherein part of the outside casing is cut away showing the central burner and its location in respect to the grate. Fig. 2 is a horizontal cross-section taken on the line AA of Fig. 1 showing thecentral burner 1, side burners 2 and air vents 3. Fig. 3 discloses a larger view of the central burner 1 and the grate 4 and Fig. ishows a horizontal section of the burner 1 taken on the line BB of Fig. 3.

It has been common in garbage incinerators burning gas, to have the flame below the grate and directed up into the mass of garbage that is placed directly on the grate. With the garbage incinerator of such construction the flame acts only on the bottom of the. mass of garbage, serving to ignite that portion slowly, but the action of'the flame in reaching the middle and upper part of the garbage is exceedingly slow and there is first an action of drying the mass" out through the heated air and gases arising from the burningof the lower portion and the upward progress of the flame is exceedingly slow. A further difliculty experienced in common types of garbage incinerators, is that a mass of ashes and unburned for which it is adapted. The section shown in Fig. 2 also discloses holes 9 in the pipes 2 and these holes may be spaced vertlcally in these-pipes in corresponding positions as the holes 7 and 8 are spaced in the central burner. When the incinerator of this type 1s filled with garbage and the gas ignited,

flames are shot out horizontally from the holes 7, 8 and 9, the flame from the holes 8 spreading radially belowthe grate and up through the grate into the garbageresting thereon. The flames from the holes 7 will extend substantiallv horizontally into the mass of garbage throughout practicall its entire height and the same action wil be had by the flames from the holes 9. The result of this application of a number of flames distributed throughout the mass of garbage results in a substantially complete combustion of the mass in a short period of time.

Reference to Fig. 4 discloses the shell 10 surrounding the central pipe 6 having ver' tical slots 11 therein. When the burner is in operation, the flames extend through these slots into the mass of garbage and the wall of the cylinder 10 serves to prevent the garbage from getting close to the pipe 6 and either shutting ofl' the flame or having 1t lmpinge upon the garba e at a point Vlghfilfi it would not have the ighest degree 0 eat. a

The ribs'12 disclosed in Fig. 2 serve a similar purpose for the side burners 2.

The vertical chambers or air vents 13 Fig. 2, furnish a means of allowing gases to escape upward when the incinerator is full of garbage and prevent a chokingup and a possible explosion from the ignition of an accumulation of unburned gases and also help to provide air for complete combustion of garbage.

Reference to Fig. 3 also discloses the vertical slot 11 extending below the grate to the point 14, providing air for the flames in the central burner l and preventing the choking up by ashes or refuse at the grate surface.

While I have described and illustrated my invention with one particular type of central burner, and side burners, I wish it understood I do not confine myself to this particular arrangement of parts as described as it is evident my invention may be applied in various-manners within the scope of the following claims:

1. In a garbage incinerator the combination of a chamber for burning garbage, a grate at the bottom of said chamber, a pipe extendin from a point adjacent to said grate into sai chamber and having multiple apertures adapted to serve as gas ets throughout substantially its length, a guard about said pipe adapted to space the garbage from said pipe and having vertical slots therein to allow the flames from the apertures in said pipe to play upon the material to be incinerated.

2. In a garbage incinerator, the combination of a chamber for burning garbage, a grate at the bottom of said chamber, a pipe extending from a point below said grate,. and multiple apertures spaced throughout its length above said grate, a guard above said grate adapted to space the garbage from said pipe and having vertical slots therein to allow flames in said pipe to play upon the material to be incinerated.

3. In a garbage incinerator, the combinasaid pipe having vertical slots therein to protect said pipe from direct contact with substances introduced into said chamber, and allowing flames from said apertures to play upon the material to be incinerated, and vertical pipes spaced about the wall of said incinerator having multiple apertures therein adapted to serve as gas jets and guards for said pipes spaced about the walls of said incinerator, adapted to space the material to be'incinerated from said pipes, but to allow the flames from said pipes to play on the material to be incinerated.
