INGINERATOR Filed April 26, 1930 Patented May 2, 1933 JOHN ALLEN AND JOEE L. l /TCDUHALD, H:
INCINERATOB Application filed April 26,
This invention relates to incinerators.
It is the primary object of the invention to provide an incinerator particularly adapted for domestic use, in which waste material or refuse can be burned efiiciently without any fire hazard.
Another object of the invention is to provide corner members of unitary construction, which members may be interfitted and assembled above a foundation to form the incinerator inclosure; each corner member being cast as a unit of two side slab sections, the free longitudinal edges of which are adapted to join each other without additional securing means, and form a rigid, durable and fireproof incinerator body.
)ther objects and advantages are to provide an incinerator that will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation and facility and convenience in use and general eiliciency.
In this specification and the annexed drawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.
The invention is clearly illustrated in the accompanying drawing wherein,
Fig. l is a front view partly in section, of the incinerator constructed in accordance with our invention.
Fig. 2 is a cross sectional view of the incinerator, the section being taken on the line 22 of Fig. 1.
Fig. 3 is a side view of the incinerator.
Fig. 4 is a detail view of a modified form of one of the corner slabs of our incinerator; and
Fig. 5 is a detail view of the door support of our incinerator.
Fig. 6 is an enlarged fragmentary side elevation of the bracket forming the door hinge.
In carrying out our invention We make 1830. Serial No. id-7,521.
use of a box structure 6 on a divided or unitary base or foundation 7 and a stack structure 8 on the top of the box structure 6.
The box structure 6 is formed of four corner members 9, which are preferably cast the box structure. The mating side or edge 12 of each slab 11 is the longitudinal center division line of the respective trapezoidal box side, and it is formed so that an inter-- locking eilect and seal is formed at the meeting of said edges 12. For this purpose one mating edge 12 of each member 9 is formed with a longitudinal tongue 13, and the other edge 12 thereof has a longitudinal groove 14 therein. The corner members 9 are so assembled that the tongue 13 of the edge 12 of one corner 9 engages the groove 14 in the adjacent edge 12 of another corner member 9.
Another arrangement is shown in Fig. 4, wherein the longitudinal edge of one slab 11 has its outer half cut away to form an inner lap 16. @n the other slab ll of the same corner member 9 is formed an outer lap 17 to form a lap joint with the respective mating edge 12 of another corner memher 9.
The slabs 11 of the same corner member 9 are at right angles to each other, so that the four members 9 are readily assembled into an incinerator box unit of substantially rectangular cross section, with integral corners, and sectional but overlappingly joined trapezoidal, upwardly converging sides.
The corner members 9 are assembled on the base 7, which latter has upwardly extending projections or flanges 18 around its periphery, inclosing 'a rectangular recess into which the base end of the corner members 9 fit. These flanges 18 prevent the outward spreading movement of the corner members 9. The base 7 hollow andhas a grate 19 secured thereto in the usual manner, on which the charge of refuse or waste is burned.
The charge of refuse or waste is introduced into the incinerator chamber within the box 6, thru a char e opening 21, the latter being formed by aligning cut away portions of the adjacent slabs 11 on the front of the incinerator, as shown in Fig. 1. The said cut away portions are intermediate the ends of the respective mating edges 12 and complement each other.
The charge opening 21 is normally covered by a door 22, the lower edge of which has laterally extending trunnions 23 to slidably and rotatably lit a curved groove 2 1 in a bracket 26, the latter being mounted adjacent the opening 21. The opening 21 may be framed to reduce the wear on the edges thereof. The door is assembled in place by sliding the trunnions 23 thereof in the groove 2% until it is in proper operating position, then the door can be swung around its pivoted lower edge to cover or uncover the charge opening 21. In order to limit the opening position of the door 22, the brackets 26 have stops 2'? thereon, arranged at a desired angle to support the door 22 in open position and permit unobstructed introduction of refuse or waste into the incinerator.
The stack structure 8 includes a tubular stack 28 having an enlarged rectangular lower end 29 thereof recessed to fit over the top of the box structure 6 and to overlap the same, thereby to hold the upper ends of the corner members 9 against outward dis placement. The upper end of the stack 28 is slotted as at 31 and the open top itself is covered by a recessed cap 32 which ts over said stack end, limiting the discharge of: the smoke to the said slots 31. There are four such slots 31 and each of the slots 31 is covered by a suitable screen 33, as shown.
It will be recognized that a particularly facile and eflicient incinerator is provided for domestic use. The incinerator is made of cast concrete slabs or the like, it is assembled and held together as a sturdy unit, without the use of bolts or the like. The integral corners of our incinerator provides perfect seal without the use of packing or gaskets. The straight mating edges of the slabs are joined with firmness and security not attainable at mitered or beveled corner joints. The entire incinerator is easily shipped, and it can be readily assembled or disassembled by a layman, or by the unskilled labor available.
Having thus described this invention, what we claim and desire to secure by Letters Patent is:
1. In an incinerator box structure four corner pieces, each piece being formed by a pair of slabs at right angles to each other, each slab being in the shape of a half of a trapezoid, the free edge of each slab being the longitudinal center division line of the trapezoid, and the corner edges of the slabs being the inclined sides of the respective trapezoids, adjacent free edges of two of the slabs being cut away in registry with each other to form an opening in the side of the box, and means to hold the corner pieces in engagement with each other.
2. In an incinerator box structure, four corner pieces, each piece being formed by a pair of slabs at right angles to each other, each slab being in the shape of a hall of a trapezoid, the free edge of each slab being the longitudinal center division line of the trapezoid, and the corner edges of the slabs being the inclined sides of the respective trapezoids, adjacent free edges of two or the slabs being cut away in registry with each other to form an opening in the side of the box; means to hold the corner pieces in engagement with each other; and means on said tree divisional edges of the slabs to form overlapping joints between the free edges of adjacent slabs.
In testimony whereof, we have hereunto set our hands at San Francisco, Calif, this 15th day of April 1930.
