INGINERATOR.

Application led J'nne 6, 1924. Serial No. 718,392.

This invention relates to incinerators ory other form of furnace and more particularly to a portable type which can be transported in sections and quickly erected.

The objects being to provide a construction which may be assembled in units each unit being designated for a certain position in relation to others which may be transported in the said unit form to the site for location and erected quickly by unskilled labor without requiring vthe services of a bricklayer or a mason.

This and other objects will appear inthe following description and be finally pointed out in the appendedclaims.

Similar numerals indicate corresponding parts in all the figures of the drawings in which:

Fig. 1 is a front elevation of the improved portable ineinerator.

Fig. 2 is a side elevation.

Fig. 3 is a rear elevation.

Fig. 4 is a vertical section on the line 4-4 of Fig. 6.

Fig. 5 .is a section on line 5-5 of Fig. 6.

Fig. 6 is a horizontal section on 6-6 of A Figs. 2 and 5.

Fig. 7 is a detail of a corner of the base plate.

Fig. 8 is a detail View of a metal frame.

Fig. 9 is a detail of cement slab.

Reference now'being had to drawings by numerals, 1 represents a base plate preferably slightly greater than the entire horizontal area lof the furnace, on which are mounted angle irons 2 around the outer edge between which a slight space is left for the reception of upright members of the frame The sides of the incinerator are constructed of panels, said panels being formed of a metal frame 3 having the vertical side members 4 and the horizontal upper and lower members 5 and 6. Said frame is provided with gusset plates 7, securely bolted at the fractory and insulating material protected on lts outer face with a facing 9 of Russia iron or other material having a finished and anti-rust surface.

Vhere openings of any character are necessary such as a stoking door 10 or an ash door 11, as seen in Fig. l, said openings with their closures are formed in a metal plate which is mounted in the frame and secured therein by bolts 12.

As stated above, the several panels with the necessary openings are fabricated at the factory and are transported to the site for erection. The base plate is located and the panels are stepped with their lower edges in the space between the channels 2 2 mounted on the base plate and brought'up into position and secured by bolts 13. Panels of various Widths and provided with openings where necessary, are secured as above described.

At the corners are provided Z-irons 14 adapted to be bolted as seen at 15 to the T iron of a panel at the end of the furnace, and project 'around and is bolted to the outer face of one of the panels at the side or front of thefurnace (as seen .in Fig. 6) and is bolted at 16.

The outer insulating slab 8 is preferably constructed of diatoniaceous earthy material and cement having high insulatingvalue and of low specific gravity and also of light weight construction, the combination having approximately the same co-eflicient of eXpan` sion as that of the meta-l frame which incloses it.

After the outer casing or shell formed by the assembling of the panels referred to are erected, the interior lining constructed of refractory blocks is arranged, each being so indicated as to represent its position and when assembled provide the ash chamber 35 over which the grate supporting channel 36 is located, and on which the grate bars 37, of any preferred construction, rest. Over the grate is the fire chamber 17, to one side of the fire chamber 17 is arranged the drying hearth 18, having a concave upper surface. Leading into the furnace over the drying hearth is the charging opening 19, consisting of the chute preferably of steel plate in which is mounted a vertically slidable guillotine door 20 provided with a counterweight 21 connected by a exible cable 22 over sheaves 23 to facilitate the adjustment of the door 20.

The combustion chamber 24 is separated from the firing chamber 17 by a l .artition 25 through which a passage 26 lea s. from d1- rectly over the drying hearth through'wlnch the products of combustion are drawn from the fire chamber over the drying hearth and out through said opening into the combustion chamber. Leading into the combustionl chamber is a clean out door 27 through which 4the ash in the pit of the combustion chamber may be removed.

Leading from the combustion chamber 1s the flue 28 in communication with the chimney. A damper 29 constructed of a refractory material mounted preferably in a metal frame 30 is designed to control the draft. Damper 29 is adapted to slide vertically in a guide way 31 in the masonry. Said damper is provided with a counterweight 32 connected by flexible cable 33 over sheaves 34,

4to facilitate the operation of said damper.

When the interior lining ofthe furnace is built up a slab of material similar to that used in the outer panels is placed overthe top to make a complete closure.

In using this incinerator, material to be destroyed is inserted through charging opening 19 on to the drying hearth 18, where 1t is first dried andv from which position it is stoked over on to the fire grates wlere it is consumed and the gases of combustion pass out of the fire chamber through the opening 26 over the drying hearth, into the combustion chamber where the final combustion is completed. The position of opening 26 in relation to the tire chamber provides for a swirling and retarding motion of the gases to enable more complete consumption of the gases in the combustion chamber on its way to the chimney.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A portable incinerator comprising a base plate, spaced angle irons mounted on the base plate near its edges, side and end panels stepped in the space between said angle irons and bolted together along their vertical edges, Z irons arranged at the .corners and bolted to an end and a side panel, a lining of refractory material and a top slab of refractory material adapted to rest on the lining to form a closure.

2. A portable incinerator comprising a base plate, spaced angle irons mounted on the base plate near its edges, side and end panels consisting of metal frames, slabs of insulating and refractory material mounted in the frames said frames adapted to be stepped Vin the space between said angle irons, and
