Patented July 12, 1932 UNTED STATES PATENT oFFlcE INCINERATOR Application filed December 27, 1930.' Serial o. 505,105.

The object of the invention is to provide a domestic refuse incinerator for the practical destruction of wet and/or dry miscellaneous refuse, such as usually accumulates around an apartment or household, and one from which tin cans and the like, as well as ashes, may be readily discharged into an ash pan.

`With the above and other objects in view, reference will be made to the accompanying drawings forming a part of this specification,

and wherein Fig. 1 is a view in front elevation of the complete invention.

Fig. 2 is a vertical transverse sectional view looking from the front.

Fig. 8 is a transverse sectional view taken on line 8-8 of Fig. 6.

Fig. 9 is a fragmentary bottom view of a portion of the burner unit.

Fig. 10 is a detailed plan view of the shak-` ing and dumping bottom grate.

Fig. 11 is aside elevation thereof.

Fig. 12 is a detailed view in side elevation of the grate cone.

Fig. 13 is an edge view thereof.

Fig. 14 is a horizontal sectional view taken on line 14-14 of Fig. 12, and

Fig. 15 is a view in front elevation of a i' fragment of the rear burner support.

Referring to the drawings, referencenumeral 1 indicates the front wall, 2 the side walls, 3 the rear walls, and 4 and 5 the top gand bottom walls respectively of the metal outer casing of the incinerator. The top 4 is provided with an outlet liuc 6, and the front wall 1 is equipped with the refuse supply door 7, and ash door 8. A draft shutter "9 of well-known type is provided in the refuse supply door 7 and the ash door8 is equipped with foraminous draft panels 10.

The metal casing is lined with irebrick front 11 sides 12, back 14, and, top 15, the

latter having a neck portion 16 extending into 55 the flue 6, and the front firebrick lining has openings 17 (only one being shown) coinciding with the openings for the doors 7 and 8.

An ash pan 20 is removably disposed upon 60 the bottom 5 and at a suitable distance thereabove is located a gaseous or other iuid fuel burner comprising front and rear portions 21 and 22 respectively and side portions 24,

making up a rectangular burner member, the 05 front and rear portions 21 and 22 respectively of which engage the front and rear lirebrick linings'll and 14 respectively, while the burner side portions 24 are spaced equal distances from the irebrick side linings 12.

The front, rear and side burner portions, which are hollow andconnnunicate with each other and receive full supply through a tubular neck 25 which extends through the front rebrick'lining 11 and has its flanged ends 26 75 suitably secured to the metal casing front 1 by bolts or screws 27. Agooseneck 28 having flanges 29 secured to the front cas-ing wall 1 by the samefastenings 27, extends telescopically into the tubularneck 25, and has vcoIl-v 8 nection with a suitable source of fluid fuel supply.

The burner which is more or less inthe shape of an annulu's or ring, is provided in each of its front, rear and side portions with parallel 'horizontal top and bottom walls 30 and 31 respectively and parallel vertical i11- ner and outer walls :32 and 33 respectively.

TheV inner walls 32 `of the burner portions 21, 22 and 24 adjacent their right angular oil' o set or shoulder 34 which merges vinto adownwardly and outwardly curved wall 35, and the outer walls 33 of the'burner side portions 24 are correspondingly formed. The'offsets or shoulders 34 Vprovide an overhanging beneath which the burner nozzle openings 37 are located. Each of these openings'is formed in a boss 38 and incline to` project theiriiames slightly downwardly from a horizontal plane.

The bosses 38 set suiciently back from the 100 planes of the vertical walls of the burner to permit free dropping :oit ashes without the same coming into :contact with the burner nozzle openings 37 to clog the same.

Arranged against the inner face of the fire- {brick back 14 is a plate 40 having legs 41 resting upon the bottom 5, and the upper edge of this plate is notched as at 42 to form a saddle in which is seated the rear end portion 22 of the burner.Y Y

Each side burner portion 24e adjacent. its ends, is provided with an upstanding lug 43 on which the bottom edges of inclined side grates 44 rest, these side grates being provided on their unexposed faces adjacent their lower portions with spacer lugs 45, which eX- tend downwardly and engage the outer side walls of the burner and outwardly to engage the inner faces of the iirebrick sides 12, as

` shown in Fig. 2. The upper ends of the side g-rates are' beveled as at 46 and engage lthe lirebrick sides 12. This construction permits ready removal of the side grates 44.

Extending centrally across the middle portion of the one piece burner casting from one side portion 24 to the other is an integral spider 47 formed centrally with a central bearing 48 which latter has upper edge slightly above the burner body proper. Upon this upper edge of the bearing 48 rests a grate 49 which forms the bottom of the refuse basket, the grates forming the sides, and the firebricks 11 and 14 the front and back respective- A ly of said refuse basket or container.

miy

The grate 49 is provided with a central stub shaft 50 which passes snugly through the opening in the bearing 48 to a point below where its squared end 51 receives a shaking arm 52, slotted at 53' to receive an upstanding pin 54 on a second shaking arm 55 which extends through the ash pit opening 17 and front casing 1 where it terminates in a handle 56. This shaking arm 55 swings n on a pivot pin 57. A cotter pin 58 secures the shaker 52 in place.

The bottom grate 49 comprises a central bar portion 60, centrally of which is the said stub shaft 50, and each end of this bar por- A E tion 60 terminates in slotted grate wings 60 50i said wings extending beyond each side edge of said bar portion 60 and providing ash' discharge openings or notches 61. The upper-face of the bar portion 60 is provided with ears 62 which engage webs 63 of a cen- I tral cone 64 to center the same upon said bar portion 60 of the bottom grate. Screws 65 pass through openings 66 in the bar portion 60 and thread into openings 67 in the said webs 63 of the cone 64. The cone 64 is elon- 60.

gated in the direction of the length of the bottom grate 49 and is provided with ports 68 through which air and the hot burner gases circulate into the refuse.

In operation, wet and dry refuse, including wasteV paper, garbage, and even tin cans,

are dumped through the refuse door 7 and fall upon the grate members 44 and 49 and surround the cone 64. The burner is run continuously as when the refuse is very wet and requires drying, or only when needed as when the refuse is suliiciently dry or contains sufficient dry content as to readily ignite and be consumed.

It wet, the heat from the burner rises around the entire interior of the burner ring and around its outer sides, passing upwardly through the bottom grate wings 60', the spider 49, the side grates 44, and the central cone 64, and through every part of the refuse to effectively dry the same. The presence of a limited amount of tin cans in the refuse separates the particles of refuse and aids the circulation of the hot gases through the refuse. l/Vhen the burner is not running, then. air circulates in the same manner, and While the drying action is slower, in time will effectively dry the refuse', so that upon kindling with a paper or upon lighting the burner, the refuse readily burns into a state of, complete incineration. l

When it is desired to dump any accurnus. lation of unburned refuse, including thetin cans, the handle 56 is swung laterally and the pin 54 working in the slot 53 swings the bottom grate 49 from the Fig. 3 to the Fig. 5 position, in which latter position the grate notches 61 coincide with the openings in the burner on each side of the spider 49 and permit the refuse and cans to drop into the ash pan 20. Then only fine ashes are to be displaced, the grate 49 needs not to be swung the entire 90 degrees.

In its turning movement, the wings 60 of the bottom grate pass over the upper surface of the burner and beneath the bottom edgesor" the side grates 44, within the space provided by the spacer lugs 43, and the elongated cone swings virtually across the. entire refuse basket pushing the wholly or partially consumed refuse and the tin cans to either end of the refuse basket or compartment, and these ends being deprived of all bottom support for the refuse, the latter falls into the ash pan 20.
