INSERTQBLE GRATE FOR BOX STOVES Filed April 24. 1928 E566: C'ox,

Patented June 17, 1939.

,UNITED STATES ELLA COX, OF MAGNOLIA, NORTH CAROLINA INSERTAIBLE GRATE FOR BOX STOVES Application filed. April 24,

This invention relates to stoves, and especially to an insertable grate for box stoves.

The main object of this invention is to provide a well known type of wood-burning stove, known as a box stove, with a grate that can be passed into the door thereof and assembled therein, which is comparatively simple and cheap to manufacture, and which is very practical and useful in utilizing said box stove for the burning of coal, lignite, chips, etc.

Other objectsand important features are pointed out or implied in the .following details of description in connection with the accompanying drawings in which:

Figure 1 is a front view illustrating a body of a box stove having my grate therein, illustrated by dotted lines.

Figure 2 is a longitudinal vertical sectional view taken in the line 2-2 of Figure 1.

Figure 3 is a vertical cross sectional view taken in the line 33 of Figure 2.

In these views, the stove legs and other parts are omitted, which have no direct connection with the grate and its relation to the box stove.

Referring to these drawings in detail, in

which similar reference numerals refer to similar parts in the several Views, and in which the stove body or box 4 has a doorway 5, flanges 6' at opposite sides of the doorway, a hinged door-closure 7, a draft-apron 8, a removable cover 9 for the latter, and an opening 10 through which coal and the like may be introduced and which may be closed by means of the usual cover (not shown), the invention will now be described in detail as follows:

A horizontal grate member 11 is provided with supporting flanges 12 at its opposite sides, so its main part is spaced above the floor of the box stove 4, and ashes may be drawn forward into the draft apron 8 and there removed with a shovel, as is usual. This member 11 is provided with several openings 1928. Serial No. 272,523.

13 near the-front end, but at a distance inward from the front end.

An upright grate member 14 has legs 15 the lower parts 16 of which are reduced so they can be passed through the openings 13 and fit loosely therein, while the upper parts of these legs are too large to enter the open ings 13, so their shoulders 17 rest on the top of the grate member 11. By the provision of thisform of legs 151617, spaces are provided at 18, directly over the grate member 11, and through these spaces 18, a pokercan be thrust along the top of the member 11, under the coal or other fuel, so as to dislodge the same from its direct contact with the grate, to cause the ashes to fall throughthe grate, and thereby to permit a draft to pass up through the grate and throughthe fuel. Moreover, because of the loose engagement of the parts 16 in the openings 13,. the grate member 14 can be pushed inward against the fuel, so as to force it rearward, and then, when it is released, spaces will be provided between the grate member 14 and the fuel, so air can pass 'up between the fuel and grate member 14, for

aiding combustion of the fuel, and for protecting the grate member 14 against becoming overheated.

It will be seen that the grate member 14 is wider and of less height than the doorway 5, so it can be passed through the doorway, and then turned to bringits parts 16 into position for lowering them into the openings 13; and when thusengagedwith the grate member 11, it will be seen that the grate member 14 extends approximately to the side walls of the box 4, and its ends. are adapted, to lean against the sides or flanges 6, because of its width being greater than that of the doorway. A considerable space is provided between the upper edge of the doorway and the upper edge of the grate member 14, and through this space, a poker can be thrust for shifting the upper part of the fuel, and-besides, long pieces of wood can be passed through this opening,

(for making quick emergency fires) without disturbing the grate member 14. It will be seen that the upper part of the grate member 14 is considerably wider than its lower part, and this is necessary for providing an ample overlapping of the upper end of the grate on the flanges 6, especially in box stoves of which these flanges 6 are relatively narrow.

Even though the width of the grate member 11 is greater than the width of the doorway 5, and may be greater than the height of the doorway 5, nevertheless, it can be passed through the doorway while leaning it so that one edge will be adjacent to the right lower side, while the other edge will be adjacent to the left upper side, and when it has passed through the doorway, it can be turned hori- Zontally, so its flanges rest upon the floor of the box 4:.

Although I have described this embodiment of my invention specifically, it is not my intention to limit my patent protection to these exact details of construction and arrangement, for changes may be made within the scope of the inventive ideas as implied and claimed.

What I claim as my invention is:

1. In a grate for a box stove having a doorway that is wider at its middle part than at its lower end and having flanges extending inward at opposite sides of the doorway; the combination of a horizontal grate-member provided with supporting flanges at its opposite edges, said grate-member having openings therein at points near its front part but spaced a considerable distance from its front part, and an upright grate-member having depending legs provided with reduced lower ends that normally extend through said openings, and are loose therein, the upper parts of said legs being too wide to extend into said openings, so spaces are provided between them for receiving a poker for poking the fuel which is directly on the first said grate-member, the upper part of the said upright gratemember being wider than the lower part and providing a secure engagement with the said flanges of the doorway, said upright gratemember being normally inclined forward and adapted to lean against said flanges of the doorway, said upright grate-member being of less height than said doorway, so it can be passed through said doorway and placed into engagement with said openings of said horizontal grate-member.

2. The combination with a. box stove that includes a doorway which is wider at its middle part than at its lower part and has flanges extending inward at opposite sides of the doorway; of a horizontal grate-member that is relatively long from front to rea r and is; adapted to be passed lengthwise through sa dd'oorway and is provided with flanges to supp rtitsmain part at a distance above the floor ofsaid 'stove, said grate-member having openings in its front end portion but at a considerable distance inward from said doorway, and a forwardly leaning grate-member having legs extending through said openings while its upper end rests against the said flanges of the doorway, the said upright gratemember being of less height than said doorway and adapted to be passed therethrough and to have its legs engaged with said openings of the grate while the latter is seated in said stove.

In testimony whereof I affix my-signature.

ELLA COX.
