Specification of Letters Patent.

Patented May 4, 1909.

Application filed 11113 20, 1908. Serial N0. 444,3 4.

T all whom it may concern:

Be it known that I, BENJAMIN C. Fox, citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Refuse-Burners, of which the following is a specification.

My invention relates to improvements in receptacles designed to hold paper and other waste material, to be burned without removal from the" container. j

The chief objects of the improvements which form the subject matter of this application are :to provide a repository for loose and inflammable material so constructed as to permit access of airto every part of the contained mass, so that free combustion may take place without resorting to artificial draft; to so design and construct the receptacle that the entire contents may be con sumed Without danger of communicating the fire to surrounding objects; and to supply a portable combined furnace and receptacle that will be durable, economical to manufacture, and capable of causing complete incineration. of the contents.

Other objects of my invention, statcd more in detail, are:to provide a refuse burner constructed largely of opcn-worlc material, such as expanded metal, thus producing a receptacle of light weight propor-- tional to its capacity; to furnish a rigid frainc for reinforcing and so porting the perforated material, and to supp y means for protecting the raw edges of the expanded metal where cut.

A further advantage is observable in the removabili'ty of the grate and extension, the latter adapted to admit air into the center of the mass when burning, thus promoting complete combustion.

Another feature of importance is the shape in which the parts are made, the outer we ls being in the form of a truncated cone, and

the inner member conical, thus pern'iitting the parts to be nested so as to economize space for transportation.

I accoln l" h the desired results by means of the device illustrated in the accon'ipanying drawing, forming a part of this application, and in which Figure 1 is a side elevation of the preferred form of my improved refuse burner; Fig. 2 is a vertical section on line 2 2 of Fig. 1 l ig. 3 is avertical section, with seine portions .broken away, showing a modification in the l t l i i construction of the grate supports, and Fig. 4 is a top plan view of the grate shown in Fig. 3 and supports therefor, removed from the receptacle.

Referring to the details of the drawing, the numeral 5 indicates a basket-like receptacle, having the general shape of an inverted truncated cone. I prefer to use expanded metal for the walls of this receptacle, although woven wire fabric. may be substituted if preferred. The upper and lower ends of the receptz'rcle arc reinforced and protected by metal bands 6, 7, of U-shape'or channel form, which are riveted thereto. The-sides of the receptacle are stiffened by' vertical metal strips 8 placed upon the outside at spaced intervals, and riveted at their ends to bands 6 and 7 by rivets 10, which pass through the strips both walls of the bands and the expanded metal. The strips 8 are further secured to the expanded metal sides by additional rivets l]. The structure thus described is formed with both ends open, and to support the contents a grate 12 in the form ofain annular ring or plate having a central circular opcning 1;}, and j'irr'ividod with a plurality of smaller apertures 13 to permit. the air to pass freely during the process of combustion is arranged within the rcccptsclc. This grate is supported at a slight distance above the lower margin of the receptacle by a framework consisting of two hangcrs lat, which are dirccted radiall \'.bcncath the said grate, and fastened thcrcto by rivets 'lhc llllrltilOPUl'lrlOll of eachhanger is bcnt at the inner margin of the central opening .13 of the grate and extended upward in the manner shown, forming an invcrtcd V, lti, the apex of which is indicated at 17, where the two hangers cross each other. The outer portions 17 of the hangers are bent sharply upward at the periphery of the grate 12, and lie parallel with and against the inner surface of the receptacle wall, where the extremities are recurved to form hooks 18 (as shown in Figs. 1 and 2) which pass through the walls of the lt-BCQP- taclc and are received in suitable openings 19 formed in the supporting straps 8, thus affording a firm support for the grate, and permitting its ready removal by disengaging the hooks, which may be done by raising the grate and hangers, the -o cn.ings 19 being of suflieient height to permit this to be easily done, and then springing the hangers inwardly until the hooks'are free. The mid- (He portions of the hangers form a sup aort for a cone-shaped member 20, whic is placed over the said support and riveted thereto as shown at 21. This cone is preferably constructed of the same material as the wall of the receptacle, forms acovering for the grate opening 13, and permits the air to penetrate freely to the center of the burnomitted, the frame portions 17 being permanently secured to the receptacle walls by rivets 24. While in this case the grate is not detachable the cone can be lifted therefrom. It is apparent that this cone is subjected to the maximum degree of heat generated in the burning mass, and it is therefore likely I to become deteriorated before the outer structures or the heavier supports and in such case can be economically and conveniently replaced by a new cone.

The reinforcements 8, comprising the vertical outside straps, and, the hangers with their V-shaped extensions 16, afford a valuable and durable framework, very essential in a structure composed of the material having the light weight which it is desirable to employ for the main walls. Not only does this frame defend the appliance against rough usage but also prevents the Warping to which the light fabric may be liable articularly when unusually heavy refuse is burned, the central apex of the cone 20 being especially prone to become deflected without the 3 support given by the V-shaped portions of ie support and maintain same in normal shape.

2. In a refuse burner, the combination with a perforated rec'eptacle,- of channeled bands engaging the ends of the receptacle, vertical reinforcing members secured'at each end to said bands, an annular'gratc provided with a central opening, hangers supporting said grate and removably attached to the re- 'ceptacle abovcthe grate, said hangers projectingupwardly through the central opening in the grate, and a perforated air supplier supported by the projecting portions of the hangers and arranged above the central opening in the grate.

3. In a refuse burner, the combination with. a perforated receptacle, bands engaging the ends of the rece tacle vertical reinforcing strips secured to t e receptacle and bands, an annular grate having a central opening, a conical air supplier arranged above said opening, hangers extending across the interior of the receptacle and supporting the grate, the ends of said hangers being bent to project upwardly above the grate and terminating in hooks removably engaging openings in the reinforcing straps.

In testimony whereof I afiix my signature in the presence of two witnesses.
