incinerators for burning rubbish `and the like. i

y In spite of the great demand for house'-1 hold incinerators in many localities, Ythey are not stocked by most dealers due `to the eX- cessive space they occupy bothin storageand during transportation, due to their bulk and hollow nature. Y

Itis, therefore, an vobject Aoi my invention Ato providean incinerator which may be col- 'lapsed'intoa package of comparatively small vcompass for ltransportation and storage, .and .yetfbeeasily and quickly erectedby the purchaser without 'the aid of vtools or skilled y.labor.

I have also providedV certain novel features of construction which will be explained in detail in the following specification, reference being made 'to Vthe accompanying drawings, wherein :f

In the drawings, l.the various elements of the incinerator are so proportionedand relatively arranged that the erected structure isv in the nature of a-square. base, truncated pyramid, but it will be understood it .lies within the scope ofV my invention4 to so vary the proportions of the elements that the ini cinerat-or may be of any desired shape possible to the combinations set up in certain of the appended claims. While I will describe the structureas made upof corrugated sheet metal plates, it will be understood Vit lies within' the scope of the invention, in itsV eration.

broaderaspects, to use other material for the purpose. I A .Front and rear'panels 10 and 11, respectively, are preferably made up-of corrugated sheet `metal and are hingedly connected at their side edges to `side panels 12, each of thel latter being made up'of corrugated sections `13 and'l/l which are 'hingedl-y connect# :ed along theirverticaliy extending edges.v In the illustrated .incineraton each side sec--A tion :is Ysubstantially one-half Vthe width of the front or rear panel, butit will be under-L rstood this proportion is not controlling.

I .have devised a hinge connection which `is especiallysuited `to the purpose, dueto the simplicity and cheapness of its construction, 'ease `oiia'ttachment, and effectiveness in op- Referring particularly to Figs. Gland 7, it

lwill-be noted that the two members 15v and 16 :making up each hinge, are formed of wires bent upon vthemselves to formal shank 17,

:these shanks beingV thrust 1 through alined holes 18 in theopposite sides of corrugation swells 19. The holes may be'fconveniently punched before f the cor'r-ugations 19 are The free ends 20 of the wires are spreadv transversely ofthe shank portions to prevent longitudinal displacement of the members in a given direction, while eyes 21 and 22 at the other ends of the shanks'are interengaged to form a hinge connection be. y tween sections 13 and 14. Eye 21 is formed 'byspreading the shank wires of member 15, lwhile-the doubled over shank end'of memoutward-movement at their junction when the incinerator is fully opened up, and yet the sections may be folded with outer face against outer face lwhen it is desired to collapse the incinerator (see Fig. t). In l 't yorder to prevent accidental'v folding ofthe sections, I may provide a pivotally mounted buttonr or bar 23a (Fig. 1) on one of the The corner hinges 25 which connect the front kand rear panels to the. side panels ilo are constructed similarly to those just described, except that shanks 26 extend through inwardly projecting corrugation swells 27, and the twoA shanks of a given hinge extend at right angles'to one anotherY tent. However, this overlap does not intertere with inward collapsing movement of the adjacentpanels tothe position or' Fig. 4.

Cover 30 is made up of screening 31, preterably having a metal binding strip 32 thereabout. The upper edge o Athe rear panel 11 is turned over at 33 to support a cross rod 34 which serves as a pintle or hinge pin foi-,cover 30. Rods 35 serve v. asreinforcement for screen 31 and to attach the cover hingedly to rod 34. The forward end of the rods preferably hook through the screen at 36, while their opposite ends 3T are bent more or` less loosely around bar 34. The rods may be wired or otherwise suitably secured to the screen at 35a. Itis self-evident that this hinge connection between rear panel and cover permits the cover, to be raised for the insertion of rubbish when the incinerator is erected, orto be turned clear over into the vposition of Fig. 4 whenthe incinerator is to be collapsed. Front panel 10 has a draft opening 38 overk which isy hung door .39, member 40 serving both as reinforcement for the door and as a hinge connection between panel and door. Member 40 is a rod bent into substantially U-shape, the loop 'end 41 passing through door slot 42 and being bent und-er the inner tace of the door as clearly shown in Fig. 8. The legs 43 of memberx40 are further spread at 44 and pass through holes 45, provided in the angular extension 46 of the door, and thence pass throughy holes 47 in panel 10. The leg ends 48 are `then bent behind the inner face of the panel to prevent door displacement, but they permit the door to be swung open or shut. Y

The shank 49 of hook 50 extends through panel aperat-ure 51, transverse extensions 52 being disposed against the inner face of the panel tohingedly connect the hook to the panel. When it is desired to hold door 39 in open position, hook 50 is engaged with door extension 46, as clearly illustrated in Fig. 8, When the door is closed,'hook 50 hangs down in a position adjacent the iront panel. Y

It will be seen I have provided a strong, durable incinerator which may be folded so as to occupy a minimum of space or may be fully erected without the aid oi tools. The various hinge connections are such that none of their elements are joined by rivets or the like, lending greatly to the easy and cheap fabrication of thedevice, without in l any way impairing its eiiiciency or useful life. j l

It is to be understood, I wish the drawings and description to be considered merely as illustrative of and not restrictive on the broader claims appended hereto, for various changes in design, structure and arrangement may be inade without-departing from the spirit andscope of said claims.
