Description:
BACKGROUND OF THE INVENTION
It is well known that conventional fireplace grates are ineffective for burning newspapers that are left folded and stacked in a pile forming a plurality of parallel layers. As combustion takes place on conventional grates, only the outer layers of paper burn. Air is unable to permeate through the layers to support combustion of the inner layers of paper. Consequently, a large percentage of the newspaper is left partially or incompletely burned which means that the partly burned newspaper must be removed from the fireplace.
Consequently, people have thrown their newspapers in garbage cans to be disposed of through normal channels, instead of burning them in their fireplaces.
PURPOSE OF THE INVENTION
One of the principal objects of this invention is to provide a fireplace grate apparatus that enables the user to effectively burn newspapers and the like in his fireplace.
An additional object of this invention is to provide a grate apparatus for burning newspapers for a hotter, longer lasting fire with less waste then could be expected when using a conventional fireplace grate.
A further object of this invention is to provide a combination fireplace grate apparatus that may be used in the conventional manner for burning logs or wood and it may be used alternatively for burning newspapers and the like by merely changing the orientation of the apparatus.
It is also an object of this invention to provide a dual purpose fireplace grate apparatus comprised of a framework of expanded metal for the containment of burning material either in a horizontal or an upright position to facilitate ventilation along the burning surfaces.
A still further object of this invention is to provide means for disposing of newspapers in a manner which is relatively pollution free.
Another object of this invention is to provide means for disposing of newspapers without having to clutter up garbage cans, etc.
These and other objects and advantages of this invention will become apparent upon reading the following detailed description of the preferred embodiment.
GENERAL DESCRIPTION
A preferred and alternate form of this invention is shown in the accompanying drawings, wherein:
FIG. 1 is a perspective view of a fireplace grate apparatus embodying the principal elements of this invention;
FIG. 2 is a sectional view of a fireplace with the grate shown positioned in an upright manner for burning newspapers;
FIG. 3 is a sectional view of a fireplace similar to FIG. 2 except showing the grate in a horizontal orientation for burning logs, etc. in the conventional manner; and
FIG. 4 is a fragmentary side view of an alternate fireplace grate apparatus .
Referring now in detail to the drawings, particularly FIG. 1; there is shown a fireplace grate apparatus 10 that may be considered a combination fireplace grate. It may be utilized in the traditional or conventional manner for burning logs, etc., or it may be used in an alternative manner for burning newspapers, magazines and the like to reduce the paper to ash.
The fireplace grate apparatus has an L-shaped grate framework 12 of expanded metal forming a plurality of interconnected bars 13. The bars 13 are spaced in such a manner as to form diamond-shaped holes 14 throughout the grate to provide excellent ventilation, while at the same time supporting the materials being burned. The framework 12 has end edges 12a and 12b and side edges 12c and 12d.
The framework 12 is curved at 18 to form the L-shape with a shelf 16 extending outward at a substantially right angle to a main platform, 17. The L-shaped framework 12 is of sufficient size to handle a number of newspapers at one time. A sheet of newspaper is generally approximately 17 inches by 23 inches and when folded in half has dimensions roughly 17 inches by 12 inches. The width of the framework 12 between the side edges 12c and 12d is somewhat greater than 17 inches and the distance from the shelf 16 to the end edge 12b is equal to or greater than 10 inches. The shelf 16 projects outward from the main platform 17 sufficiently to support a number of newspapers along their edges as shown in FIG. 2. The main platform 17 has a cross bar 21 welded across the end edge 12b.
The fireplace grate apparatus has a support means for supporting the grate framework in either of the alternate positions--(1) with the main platform 17 extending upwardly at an incline angle as shown in FIG. 2 or, (2) with the platform 17 substantially horizontal as shown in FIG. 3. The support means supports the grate off the floor to provide good ventilation to support combustion and also enabling the ash to filter through the grate and fall onto the floor away from the burning material.
The support means includes a U-shaped member 23 welded in an inverted orientation to cross-bar 21. The U-shaped member 23 has leg members 24 and 25 that extend downwardly from the platform 15 and an upper section extending upwardly to form a front retainer 26 to prevent logs, etc. from rolling off the grate framework when the grate is positioned in the horizontal orientation.
The support means also includes back legs 30 and 31 that are welded to the grate framework adjacent the bend 18. The legs 30, 31 extend outwardly from the grate at an inclined angle to the platform 17 so that the legs 30 and 31 will support the grate off the fireplace floor independently or whether the grate is positioned in the upright position or in the horizontal position. The support means supports the grate in the upright position with the platform 17 extending upward at an angle greater than 45° with respect to the floor.
The fireplace grate apparatus is designed for use in a fireplace 40 having a front opening 41 and a floor 42, side walls 43 and a back wall 45. The fireplace also has a chimney opening 46 for exhausting the combustion gas products to the atmosphere. A damper 47 is normally mounted in the opening 46 for opening and closing the opening as desired.
When it is desired to utilize the fireplace grate apparatus 10 for burning newspapers, the newspapers are piled on top of each other on the platform 17 with the paper layers substantially parallel with the platform 17. The edge of the newspapers engage the shelf 16. The grate apparatus is then pivoted upward until the U-shaped member 23 engages the back wall 43 as shown in FIG. 2. Alternatively the papers may be loaded when the grate apparatus is already in the up position. In this position the platform 17 extends upwardly at an inclined angle that supports the papers in an upright manner to enable sustained combustion to occur. The shelf 16 extends toward the back wall to support the edges of the newspapers as shown in FIG. 2. The rear legs 30 and 31 support the shelf 16 spaced from the floor 42. The user than puts a match to the newspapers. It has been found that the newspapers will burn very efficiently reducing them to an ash with little or no carbonaceous product remaining. This in stark contrast to the normal result in which the newspapers are partly or half burned leaving a mess in the fireplace.
When it is desired to use the fireplace grate apparatus 10 in the conventional manner for burning logs, the fireplace grate is pivoted to the horizontal position with the platform 17 supported by the legs 24, 25 and 30, 31 substantially parallel with the floor to receive the logs. The upper part of the U-shaped member 23 becomes a front retainer 26 to prevent the logs from rolling from the grate toward the front of the fireplace and the shelf 16 prevents the logs from rolling from the grate towards the back of the fireplace. The legs 24, 25, 30 and 31 support the framework 12 spaced from the floor to provide good ventilation and to permit the ashes to fall through the diamond-shaped holes to the floor.
In an alternate embodiment shown in FIG. 4, the fireplace grate apparatus can be modified for use in burning newspapers only, in which the U-shaped member 23 is removed and new leg elements 36 are welded to the shelf 16 adjacent edge 12a for supporting the grate in the upright manner with the side 17 extending upwardly at an inclined angle greater than 45° and the shelf 16 extending rearward in a slight upward angle to support the edges of the newspapers. In such a configuration, it is not necessary to have holes in the side 17.
It should be understood that the above described embodiments are simply illustrative of the principles of this invention and numerous other embodiments can be readily devised by those skilled in the art which contain this invention. Therefore, only the following claims are intended to define or limit this invention.
