PORTABLE RUBBISH-BURNER.

Specification of Letters Patent.

Patented Jan. 21, 1919.

- Application filed March 28, 1917. Serial No. 157,960.

To all whom it may concern.-

Be it known that I, ALBERT J. ROBERTS, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Portable Rubbish-Burners, of which the following is a specification.

The present invention relates to new and useful improvements in incinerators.

The primary object of the invention is the provision of a ortable incineratorfor the purpose of burning' rubbish of any combustible nature; 1

Another object of the invention is the provision of an incinerator comprising a casing containing a combustion cage of such nature that the same may be readily assembled or disassembled for the purpose of transportation or the like.

Still another object of the invention is the provision of an incinerator of the portable type designed for the destruction by fire of all rubbish such as boxes or the like either in a whole or crushed condition, barrel staves, oily ,waste matter, sweepings' and refuse and in fact any other rubbish of a combustible nature either in large or small particles.

A still further object of the invention is the provision of an incinerator or the like I which will be comparatively simple and inexpensive to manufacture, reliable and efficient in use, and readily operated.

With the above and other objects in view the present invention resides in the novel features 'of construction, formations, combinations and arrangements of parts to be hereinafter more particularly described, claimed, and illustrated in the accompanying drawings, it being understood in this connection that various minor changes in the specific details of construction can be resorted to within the scope of the appended claims, without departing from the s irit,

or sacrificing any of the advantages 0 the invention.

In the accompanying drawings;

Figure 1 is a side elevation of an incinerator constructed in accordance with the resent invention, a part of one side being bro an away and parts within the same being shown in section;

Fig. 2 is a front elevation thereof;

Fig. 3 is an enlarged view, partly in section and partly in elevation, of the burner; thesection being taken on the line 3-3 of Fig. 1, and the parts shown in elevation be ing broken away at points adjacent to the sides of the burner.

Fig.4is a horizontal sectional viewtaken through the lower end of the combustion cage and showing the grate in plan view;

Fig. 5 is'a .detail sectional view taken through a portion of the shell or casing on a horizontal plane; and 6 is a detail sectional view taken through a portion of the cage roof.

Referring now to the accompanying drawings by corresponding characters of reference throughout the several views the numeral 1.0 designates in general my improved incinerator which comprises a base 11 supported upon suitable legs or the llke such as shown at 12. These legs may be of any desired shape and size and may be arranged around the base 11 in any suitable num r.

An outer shell or casing is shown at 13 and consists of spaced lwalls 14 having suitable packing or insulating material 15 disposed therebetween. This casing 13 is. preferably of a rectangular shape in plan view and is supported at its lower end upon the said base 11 and is' retained thereon against displacement by the upstandin flanges 16 base 11.

arranged around the edge of said A suitable cover or dome 17 is positioned upon the upper end of the casing 13 and like the said casing comprises inner and outer sheets of material, 18 between which is placed the packing" or insulating material 19. This cover or dome 17 fits snugly upon the upper end of the casing 13 and can be held thereon by any suitable means such as l the bolts 20.

A plurality of standards 21 are secured to the legs 12 and extend vertically within the casing 13 to about the plane shoWn intermediate the ends of .said casing. These standards 21 support a combustion cage 22 which consists of upper and lower sections 23 and 24 formed of spaced bars of any suitable material which will stand the heat within the casing 13.

The upper section 23 of the cage 22 is preferably of a rectangular formation, while the lower section 24 tapers toward its lower end and terminates at a point slightly above the bottom or base 11 allowing sufficient space therebetween for an ash pan 25 or the like which will catch the ashes or other foreign particles falling from the cage 22.

The section 24 of the cage 22 supports a grate 26 which consists of rotatable end sec-' shaft 29.. These shafts-29 project through openings 30 formed in one side wall of the P burners .45 and the pilot burners 46f.d-,These I casing 13- and are terminally angular in cross section as at 31 for engagement with a suitable implement by means of which the grate sections 27 can be shaken.

A pair of suitable doors 32 are provided in the frontof the casing 13 by means of which access can be had to the interior of the casing below the grates for the'purpose of removing the ash pan 25 for cleaning the device. 4

As clearly shown in Fig. 3 of the drawings the sections 23 and 24 may be suitably connected at their adjacent ends as shown at 33 and at this point preferably support inwardly directed bafiie plates 34. Similar bafiie plates 35 may extend from the sections 23 and 24 in any desired directions or positions.

One side of the section 23 of the" cage 22 j is provided with an opening 36 which. registers with an opening 37 provided in the front of the casing 13; This opening 37 may be closed by a suitable door 38 which when opened provides access to the interior of the cage 22 so that the material to be burned may be disposed in the cage above the grate.

The cage 22 is provided with a suitable roof 39 which comprises a'plurality of-fire bricks or the like shown at 40 which are connected by the angle bars 41. The roof is provided with a suitable coating 42 of cement or other suitable material which acts as a binder and holds the several parts thereof in position. The angle bars 41 extend slightly below the lower edges of the roof 39 and engage the upper end of the cage 22 forming a means for retaining said roof in normal position and in Spaced relation to the closure or dome 17 providing an air space therebetween.

The opposite sides of the casing 13 are provided with spaced adjacent openings 43 and 44 through (which extend the main burners extend to points adjacent the lower section 24.

end of the cage section 24 while disposed 65.

immediately above the same are deflectors 47 which prevent any particles from falling from the cage upon said burners.

These burners 45 and 46 are supplied with any suitable fuel through the pipes 48.

In operation the cage 22 is filled with the material to be burned and assuming that the pilot lights 46 re lighted the controlling valves for the burners 45 are opened to permit the fuel to pass inwardly into the all odors or the like will pass therefrom out through the smoke stack 49 which communicates with the dome and the body of the casing through the connecting pipes 50 and 51, respectively.

Any well known means may be employed to secure the sections 14 of the casing 13 firmly together but as shown in the drawing the vertical edges thereof are extended in parallel relation as at 52 and are embraced by channel bars 53 which are riveted or otherwise secured thereto as shown at 54. This renders the seamstight and thereby contributes to the formation of an air tight compartment between the two sections 14 for the reception of the packing. 15 above referred to.

spaced relation to the casing and including a pair of superimposed sections, bafiie plates carried by and extending inwardly from said sections, a grate closing the lower end of the lower of said sections, a roof for said cage in spaced relation to the casing cover, burners mounted between the casing and the cage, deflectors disposed outside the cage and above andadjacent the burners,

said casing having normally-closed entrance penings provided therein, and the cage having an opening disposed in registration with one openingin the casing. I

2. In an incinerator, a base, legs supporting said base, a casing mounted upon' the base, a cage disposed within the casing and spaced inwardly from the walls thereof, stand'ards'within the casing and supporting said cage, said cage including upper and lower detachable sections, horizontal bafile plates disposed within said cage, said cage having an opening in one side thereof, and the casing having an opening therein in registration with the opening In said cage, a roof for said cage including a plurallty of non-combustible sections, a cover for said casing spaced above the cage roof, burners projecting into the casing and disposed outside the lower portion of the cage,

10 deflectors disposed above and adjacent the burners, and means for discharging odors from said casing andcage.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
