This invention appertains to new and useful improvements in burners of the type especially devised for burning apricot pits, of which there is an abundance in some localities.

The principal object of the present invention is to provide means whereby pits can be burned in ranges, fire places, and elsewhere. I

Another object of the invention is to provide an apparatus whereby pits can be burned in a useful manner, including means whereby the pits are uniformly fed'to a burner structure.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

' 'In the drawings:

Figure 1 represents a front elevational view showing a range equipped for burning pits and the dispenser situated adjacent the same.

Fig. 2 is a vertical sectional view through the pit burner.

Fig. 3 is a fragmentary horizontal section on line 3-3 of Fig. 2.

Fig. 4 is a fragmentary-sectional view taken substantially on line 4-4 of Fig. 1.

Fig. 5 is a fragmentary sectional view taken substantially on line 55 of Fig. 1.

Fig. 6 is a fragmentary edge elevational View of one of the ventilators.

Fig. 7 is an end elevation of one of the ventilators.

Fig. 8 is a fragmentary sectional view of the hopper.

Fig. 9 is an inside elevation of one of the end walls of the burner.

Fig. 10 is an end elevation of the double type burner.

Fig. 11 is a section on line ll|l of Fig. 10.

Fig. 12 is a side elevation of the fireplace type burner.

Fig. 13 is a section on line l3-l3 of Fig. 12.

Figure 14 is a fragmentary vertical sectional view through the hopper disclosing a modified form of closure for the chute.

Figure 15 is a perspective view of the closure removed from the hopper.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Fig. 1, that numeral 5 generally refers to the dispenser which consists of the removable top 6 on the shell I, which shell is provided with the bottom 8 in which is the discharge opening 9 (see Fig. 8). A vertically adjustable spreader in the dispenser 5 just above the discharge opening 9, prevents the pits from jamming in the discharge opening, this spreader being denoted by reference character Ill.

The dispenser5 is mounted upon legs l suitably secured to the. floor as at l2. A spout l3 extends from the discharge opening 9 and 5 through the top M of the range generallyreferred to by numeral l5 so that its discharge end is located immediately over the pit burner, generally referredto by the numeral I 6. This pit burner is installed in the fire box l'lof the range 0 after the usual grate has been removed.

The pit burner consists of the side walls l8|8 and the end Walls l9- l9. Eachof these walls is provided with a plurality of ventilating openings 20. The side walls and the upper ends of'15 supporting legs 2| secured thereto as at 22. The upper edges of the end walls and sidewalls are provided with inwardly disposed and apertured lugs 23, though a second burner generally denoted by the character IG can be inverted and 0 placed upon the one shown in Fig. 2 to convert the same into a double burner. In mounting the second burner, generally referred to by numeral-24'upon the burner l6, it is preferablyihat the ventilators generally referredto by 'the nu meral 25 be reversed from the position shown in Fig. 2, due to the inversion of the unit 24.

As can be seen in Fig. 9, the vertical edge portions of the downwardly tapering end walls l9 are provided with ribs 26 each of which is provided with a longitudinally extending V- groove 21. The lower edge of the end wall I9 is also provided with the rib 26 having the V- groove 21 therein.

The meeting edge portions of the side and end walls are joined together as shown in Figs. 4 and 5. The ends of these side walls are beveled as at 28 to engage into the V-grooves 21, and bolt members 29 are disposed through allotted bores in the meeting edge portions so as to secure the side and end walls in abutting relation.

Each of the ventilators. 25 consists of a longitudinally and transversely curved plate 30 having a plurality of ventilating openings 3| therein. Each of these ventilators 30 is provided with a head formation 32 at one end, and each of these head formations is provided with a reduced extension 33 having an upstanding lug 34 thereon, at its extremity.

The head 32 is furthermore provided with the depending legs 35 having a transverse opening therein for receiving the bolt 36. This bolt has a head 31 which engages into one of the ventilating openings 20 of the corresponding side wall l8 so as to prevent rotation of the ventilator and a nut 38 on the bolt prevents displacement of the bolt from the leg 35.

When the burner 25 (see Fig. 10) is used in superimposed relation on the like constructed burner IS, the lugs 23 of the burners are bolted together as at 39. (See Fig. 11.)

Fig. 12 shows a fire place form of burner consisting of the rear wall 28 and the front wall 20. These walls have their ends connected by the end walls l9a. These rear and front walls are equipped with the ventilators 38. A slotted bottom 26a is provided for this type of burner, and serves as a grate.

The only substantial difference in the fire place type of burner over the burner shown in Fig. 2, is that an upward extension wall generally referred to by numeral 40 is provided, the same being ornamented by suitable edge portion formations and block designs, and this wall extension 40 is provided with inwardly disposed lugs 4| which are bolted as at 421 to the lugs 43 at the upper edge of the front wall 20'.

It will be observed, that the ventilators 38 or 25 are arranged, some projecting inwardly from the front wall and the others projecting inwardly from the side wall in interlapping relation to the first mentioned ventilators, so that the pits as they are. burning, must follow a tortuous path downwardly through the burner.

A modified form of agitator and closure for the chute l3 as shown in Figure 8 is disclosed in Figures 14 and 15 wherein reference character 5a discloses the hopper from which depends the chute |3a and over the upper end of this chute and upon the floor of the hopper 5a is slidably disposed the closure plate lGa, the inner end of which is provided at its corner with upstanding ear members bb while the other end is rolled upwardly as at 0. Thus it can be seen that when the plate Illa is shoved to the dotted line position shown in Figure 14 the chute will be closed off from the hopper and the roll 0 will prevent the plate from entirely entering the hopper as it will abut the outside of the hopper. When the plate is grasped by the roll 0 and pulled outwardly the ears bb will serve to agitate the pits so that they will readily discharge through the chute I311 and when the plate has been moved to its full extent as shown in Figure 14 the ears b-b will then serve as stops, preventing complete displacement of the plate from the hopper.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is:

1. A pit burner comprising a hopper-like structure open at its top and bottom, said hopper-like structure provided with a multiplicity of openings in the side walls thereof, pit supporting plates mounted in the said hopper and projecting from opposite side walls of said hopper in interlapping spaced relation.

2. A pit burner comprising a hopper-like structure open at its top and bottom, said hopper-like structure provided with a multiplicity of openings in the side walls thereof, pit supporting plates mounted in the said hopper and projecting from opposite side walls of said hopper in interlapped spaced relation, said plates being longitudinally curved.

3. A pit burner comprising a hopper-like structure open at its top and bottom, said hopper-like structure provided with a multiplicity of openings in the side walls thereof, pit supporting plates mounted in the said hopper and projecting from opposite side walls of said hopper in interlapped
