,sppnoationalea Auggst 1a, 1926. serial No. 130,604.

This invention relates to incinerators, and ence characters designate corresponding the subject matter of the present application is designed las an improvement'on the y structure shown and described in the patent for an incinerator, issued to me on March 9, 1926, and bearing No'. 1,576,289.

The object is to provide an incinerator that may be used with either end upper-` most, each end ofthe improved device being equipped with a grate which may be dumped independently of the other and without the necessity for tiltingthe main body or casing.

Another object is to provide a reversible incinerator wherein, when the bottom grate is being used to hold material for burning, the upper grate serves to prevent escape of burning embers and the ldraft may be controlled by means `of a lid or closure at the lower end which may befopened to the desired degree for the purpose, Ior closed and held to cause a slow burning process, the upper end also being equipped with a similar lid or closure which may be fully opened to accelerate the draft or which may be closed to exclude rain, etc.

A final object isv to provide a simple, cheaply manufactured and strong and durable deviceof this character which is supported above the ground to permit the same to be freely rotated to bring either end uppermost to permit all parts to be thoroughly scraped and cleansed, each end having a dumping grate with independent, hinged lidsl connected thereto, the lids and the grates each having separate means ,for locking the same closed, and means mounted on said frame for holding the body member in upright position.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description, taken in connection with the accompanying drawings forming apart of this specilication, it being understood that while the drawings show a practicalform of the invention, the latter is not to be confined to strict conformity with the showing thereof, but may be changed or modified, so long as suchl changes or modifications mark no material departure from the salient features of the invention, as specifically pointed out in the appended claims.

In the drawings, in which similar refer- 4 parts throughout the several figures Figure 1 is a perspective view' of the improved lncmerator.

Figure 2 is a vertical section same.

Figure 3 is a horizontal section through through the the body of the incinerator.

Figure 4 is a detail perspective view of the stand forsupporting said body member .to permit the same to. be rotated.

Figure 5 is an'enlarged plan view of the v two opposite bearings for the body member` the latter being broken away.

' Figure G is an enlarged detail showing the manner of fastening the grate in position.

'The vreversible body member l is formed of suitable sheet metal formed into a cylinder open at each end and having intermediate spaced ribs 2 for strengthening the structure, and having its end edges formed into marginal beads 3 for the same purpose.

At diametrically opposite points, the. body member isl provided with `outstanding trunnions 4 'which are adapted to be removably seated to| rotate in seats or bearings 5 secured to the. upper endspof inclined llegs 6 formed of angle iron and suitably held to ether at their lower ends by horizontal bars il to constitute a strong and durable stand for supporting the body member.

The bearingsv 5 which are formed of suitable cast metal, are open at their upper ends to permit the trunnions to be easily removed therefroml and said castings are provided with depending legs .8 to which the angle irons 6 are riveted or otherwise secured, and the trunnions are` each cast integrally with outstanding arms 9 for connection with the side walls of the body member. n

One of the trunnions 4, which may be termed the rear trunnion, is provided, where'joined to the arms9, with an integral collar or flange 10 which bears against the inner face of the bearing 5, while the 'outer end of said trunnionis provided with a terminal 'flange l1 spaced-slightly 'from the outer face of said bearing to permit a limited amount'of lateral play therein,l as clearly shown in Figure 5 of the4 drawings.

The opposite, or front trunnion 4 is eX- tended and formed into a crank 1 1.;a to facilitate turning the body member in the bearings and to avoid bnrning'the hands during such operation. The front trunnion is 'l'urther provided with an enlargement'. to haar against the inner face of the adjacent hearing 5, said enlargement having a vcrticall)r disposed rib .12 to snugly (it between the sides ofthe bearing, when projectedthereinto. to prevent the entire bod member from turning in the opposite bearings. The front trunnion also carries a flange orcollar 13 `spaced somewhat from the outer side of the bearings', and having its inner face bevelled or tapered, as shown'in Figure 5, for the reception of the slotted or forked portion 14 of a lever which is fulcrumed at its lower end, to the outer face of one of the inclined legs 6, as indicated at 15. The outer face of said forked portion is correspondingly tapered or bevelled to contact with the bevelled inner face of the flange 13, and when said lever is forcedtowards the trunnion, by means of an upstanding handle 16. the action is to draw the ri-b 12 into the inner end of the bea-ring and lock the body member from turning, the said space between the terminal flange 11 and the rear bearing ,permitting such movement. When the lever handle 16 is rocked outwardly to free such engagement, the said lever is stopped in such movement by a lug 17 :formed on the lower end of the lever` com-v.

ing in contactwith l'the adjacent leg 6, as clearly shown in Figure l.

An annular ring 18 is hingedly connected, as at 19. to each end of the body member,

the `said hinges 19 being arranged in vertical alinement and permitting the rings to be swung into open position or into closed position'with an upstanding flange snugly titting around the aforesaid terminal beads 3. Each ring 18 is also provided with an outstanding concavo-convex inner portion, the inner margins of which are outwardly pressed to form annular seats 21 around the inner edges of the rings. Circular grate members 22, 'formed of heavy wire fabric are placed on the inside ofthe rings with their margins fitting in the said seats 21 and the sa me are held therein-byspaced bolts 23, thus readily permitting their removal and replacement when the .samebecome worn or burned out.

'The grate members 22 are vpreferably rounded- 'outwardly into concave-convex form, asclearly shown in Figure 2 of the drawings, and each ring 20 is provided with a lid or cover 24'hinged thereto, as at 25,

and adapted to be closed down over the ates the sai'd lids being similarly formed into concavo-convex shape in accordance with the grates.

The hinges 25 and 19 are lall preferably in vertical alinement, and are located on one side of the body member midway between the-trunnions 4, so that the lids or grates or both may be swung. downwardly or upwardly without interfering with the legs I longitudinally of the body member 1, when.

the rings are in cloz-'ed position, are each held in such position by means of a locking lever 2S, hinged to the ring, asat 29, and having a slotted intermediate portion to lit over a lug 30 carried by the body member, each hinge element having an outstanding lug 31 to arrest the outward swinging movement of the lever 28 in the unlocking operation and permit same to act as a rigid outstanding handle to force the ring into open position. l

With the body member 1 held in upright position and held from turning in the bearings 5 by the lever 14, as shown in Figure 1, the two lids 2li-may be opened, as shown, assinning that the material to be burned has been placed' in said body member. The full dralt upwardly through the incinerator will cause the rapld and complete incineration of said material upon the lower grate, while the upper grate serves to prevent an burning material from flying out of the top. The lower lid 24 may be more or less closed 'to check the draft or may be locked fully closed to cause slow burning of the contents. The upper lid 24 may also be fully closed to prevent rain from destroying the fire within the incinerator, and it will be readily seen that, after the lire has consumed said material, the ashes may be dumped on the ground by simply releasing the fastening for the lower ring to allow ring and gra to swing downwardly.

What is claimed is 1. An incinerator having a cylindrical open-ended body member centrally pivoted at opposite sides to be turned with either end up. closure rings hinged at the ends of the body and adapted to be locked over the same, foraminous grates carried by the rings and adapted to be swung open therewith and lids separately hinged to the rings and adapted' to be locked in covering relation to the grates or to be swung openl independently of the same.

2. An incinerator comprising anv openended cylindrical body, means for supporting said body to permit same to be held with either end on top, a grate located at each end of the body, rings carrying said grates and hinged to the side of the body to swing with said grate to open or closed position, means for locking the rings closed, concavo-convex lids hinged to each ring and adapted to be swung independently thereof into open or rlofzed position over the grates, and means for locking said lids in closed position on the rings. y

3. An inoinerator inrluding a sheet metal, cylindrical body open at. each end, a stand for supporting the body above the ground and permitting same to be inverted to bring either end uppermost, means for locking the body in either position, an annular ring hinged at one sid(` to each end of the bod)7 to permit said ring to be swung into closed or open position relative to the end of the body` means for looking the rings dosed, an annular seat formed in the inner edge of each ring, a eirmilar grate marginally.

held in each seat. a supplemental lid hinged to each ring to be swung open to allow draft through the grate, and means for looking Said lid in rovering relation to the grate.

4. In an ineinerator, an open-ended, Cylindrical body member having central, outstanding side trunnions. a stand having bearings in its upper end for said trunnions to hold the body member above the ground, means carried by one of said bearings for locking the body with either end uppermost, annular rings hinged in lon'vitudinal alinement at one side of the body to be swung shut over the ends of the same, means for looking each ring in closed sition, each ring vhaving an upstanding gnge around its outer margin to receive the adjacent end of the body member, the inner marginal portion being pressed to ,form a concavoronvex annulus extending outwardlyy when the ring is closed, a continuous seat formed by the inner, free edge of the annulus,'a circular grate formed of heavy woven wire and fitted and secured in said seat on the inside of the lid, said grate being bent outwardly at its center, a closure lid hinged on the outside of the ring adjacent to the ring hinge. said lid being adapted to be closed and locked over the opening in the ring and being of concavo-convex form to aoeord with the grate.

In testimony, that I claim the foregoing as my own, I have hereto aiixed my signature.

THOMAS H. LEDDEN.
