Definitions
- This invention relates to incinerators for use in burning garden, domestic or other refuse.
- Incinerators of this type are already known which are either not dismantleable at all, in which case they can constitute an eyesore when not in use, or are difficult to store, or they are dismantleable, but, owing to the direct application of heat from the burning refuse and the vagaries of the weather, eventually corrode to such an extent that dismantling becomes virtually impossible.
- a dismantleable incinerator comprising at least one sheet of incombustible material, said sheet or sheets being bendable to form a hollow truncated cone, and a support frame which is adapted to hold said truncated cone in its working position in which it has a substantially vertical attitude with its narrower aperture lowermost.
- the support frame comprises at least two rings of incombustible material which are adapted to be connected together so as to have a common axis, the rings having different diameters so that the truncated cone may be received within, and supported by, the rings when in its working position.
- the rings are connectible by connecting members which may also extend beyond the lowermost aperture of the truncated cone so as to support the incinerator with the aperture at a distance above the ground.
- an incinerator in accordance with this invention has-an advantage over the aforementioned known incinerators in that it is not only dismantleable but will continue to be dismantleable for considerably longer than the known dismantleable incinerators. This is because the relevant parts of the support frame are not subjected to direct heating-by the flames of the burning refuse. Particularly good isolation from the flames is achieved if the truncated cone is constructed from corrugated material such as corrugated iron. Thus the support frame is only subjected to an intense heat at the points of contact between the rings and the corrugated iron.
- the incinerator When the incinerator is dismantled it can be stored easily as all the parts can be packaged flat.
- the conical shape of the incinerator concentrates the combustion at the bottom and the larger top aperture of the truncated cone assists forced draughts and hence combustion. These draughts tend to rise up near the inside surface of the cone so that combustible material is being burnt from the outside whereby the material self- hops down onto the main area of combustion at the bottom of the cone.
- an incinerator of this type Because of its height and shape and its solid sides, flames are not likely to be blown sideways so that an incinerator of this type also has an advantage in that . it can be used in relatively confined areas with a reduced risk that nearby articles, such as fences or bushes, will be scorched or even be caused to catch fire.
- the cone does not have to be emptied of ash once combustion is completed.
- the ash instead falls to the ground under the lowermost aperture of the cone whence it can be spread out or collected up or even caught in a suitable resceptacle which is placed below the cone prior to combustion.
- an incinerator 1 comprises a truncated cone 2 received within a support frame 3.
- the truncated cone 2 consists of two bent sheets 10 of incombustible material, such as sheet metal, the sheets preferably being corrugated. If the sheets are corrugated, they strengthen the vertical line of the incinerator as well as facilitating bending of the sheets in the horizontal plane.

Abstract
Description
- This invention relates to incinerators for use in burning garden, domestic or other refuse.
- Incinerators of this type are already known which are either not dismantleable at all, in which case they can constitute an eyesore when not in use, or are difficult to store, or they are dismantleable, but, owing to the direct application of heat from the burning refuse and the vagaries of the weather, eventually corrode to such an extent that dismantling becomes virtually impossible.
- It is an object of the present invention to provide an incinerator in which the above disadvantages are removed or are at least substantially reduced.
- In accordance with this invention there is provided a dismantleable incinerator comprising at least one sheet of incombustible material, said sheet or sheets being bendable to form a hollow truncated cone, and a support frame which is adapted to hold said truncated cone in its working position in which it has a substantially vertical attitude with its narrower aperture lowermost.
- Advantageously the support frame comprises at least two rings of incombustible material which are adapted to be connected together so as to have a common axis, the rings having different diameters so that the truncated cone may be received within, and supported by, the rings when in its working position. The rings are connectible by connecting members which may also extend beyond the lowermost aperture of the truncated cone so as to support the incinerator with the aperture at a distance above the ground.
- Thus an incinerator in accordance with this invention has-an advantage over the aforementioned known incinerators in that it is not only dismantleable but will continue to be dismantleable for considerably longer than the known dismantleable incinerators. This is because the relevant parts of the support frame are not subjected to direct heating-by the flames of the burning refuse. Particularly good isolation from the flames is achieved if the truncated cone is constructed from corrugated material such as corrugated iron. Thus the support frame is only subjected to an intense heat at the points of contact between the rings and the corrugated iron.
- When the incinerator is dismantled it can be stored easily as all the parts can be packaged flat.
- When assembled the main wear is on the truncated cone so that only this has to be replaced, yearly or at longer intervals when necessary.
- The conical shape of the incinerator concentrates the combustion at the bottom and the larger top aperture of the truncated cone assists forced draughts and hence combustion. These draughts tend to rise up near the inside surface of the cone so that combustible material is being burnt from the outside whereby the material self- hops down onto the main area of combustion at the bottom of the cone.
- Because of its height and shape and its solid sides, flames are not likely to be blown sideways so that an incinerator of this type also has an advantage in that . it can be used in relatively confined areas with a reduced risk that nearby articles, such as fences or bushes, will be scorched or even be caused to catch fire.
- Also, the cone does not have to be emptied of ash once combustion is completed. The ash instead falls to the ground under the lowermost aperture of the cone whence it can be spread out or collected up or even caught in a suitable resceptacle which is placed below the cone prior to combustion.
- The invention is further described hereinafter, by way of example only, with reference to the accompanying drawings, in which:
- Fig.l is a side view of one embodiment of an incinerator in accordance with this invention, when in its assembled, operative state;
- Fig.2 is a front view of one of the sheets of incombustible material used in the incinerator of Fig.l;
- Figs. 3 and 4 are perspective views of rings forming parts of the support frame for the incinerator of Fig.l;
- Fig.5 is a perspective view of a connecting member forming a part of the incinerator of Fig.l; and
- Fig.6 is a perspective view of a cone support forming a part of the support frame for the incinerator of Fig.l.
- With reference to the drawings, an incinerator 1 comprises a
truncated cone 2 received within a support frame 3. Thetruncated cone 2 consists of twobent sheets 10 of incombustible material, such as sheet metal, the sheets preferably being corrugated. If the sheets are corrugated, they strengthen the vertical line of the incinerator as well as facilitating bending of the sheets in the horizontal plane. Furthermore the corrugations provide a plurality of small side chimneys which enhance draughts and hence combustion. Fig.2 illustrates onesuch sheet 10 which has the outline of a trapesium, although square, rectangular or even irregular shaped sheets may equally well serve to form thetruncated cone 2. Similarly, one, three or more sheets may be used if desired. In the embodiment of Fig.l twotrapesium shape sheets 10 are used with the short end 9 forming anarrow aperture 13 of thetruncated cone 2 and the long end 11 forming alarger aperture 15. - The support frame 3 illustrated in Fig.l comprises a
ring 12 connected to asmaller ring 14 by way of connectingmembers 16, the relative sizes of therings rings bolts 18 may be positioned for assembling the support frame. Fig.5 shows one connectingmember 16 which is also provided with holes 22',24', which holes are aligned with theholes rings bolts 18 have been inserted into the alignedholes wing nuts 20 are attached to bolt together the support. At least two connecting members are used but preferably four, as illustrated, so that the incinerator may be kept in the upright position by the support frame . alone. - In order to maintain the truncated cone in a raised position above the ground, cone supports 26, which each have a
hole 28, may be connected to the support frame in the manner shown in Fig.l. To effect this connection thehole 28 is aligned with theholes 24,24' in thering 14 and the connectingmember 16 respectively,'and abolt 18 is passed therethrough and clamped in place by thewing nut 20. Thus, theedge 30 of thecone 2 can be supported on thebase 32 of the cone supports 26. - Alternatively, the
cone supports 26 can be permanently rigidly attached to the lower ring or to respective ones of the connectingmembers 16.
