To all whom it may concern Be it known that 1, JAMES M. KILLEN, a citizen of the United States, residing at Reids, in the parish of Allen and State of Louisiana, have invented certain new and useful Improvements in Ventilated Grates for Fireplaces; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of the invention is to provide a relatively simple and efiicient grate construction for use particularly in connection with open fire places in dwelling houses and the like, designed to secure the advantages in the matter of ventilation, or draft which are impossible in connection with the ordinary open fire place as now arrangedQthe draft being obtained from the outside of the building instead of through the room in which, the fireplace is located, and to provide for the removal of the ashes also from the exterior while obtaining a more satisfactory heat value from the fuel consumed, and with these objects in view the invention consists in a construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings wherein Figure 1 is a front or inside elevation of the apparatus.

Fig. 2 is a rear or outside view of the same.

Fig. 3 is a plan view.

Fig. 4 is a vertical section on the plane indicated by the line 44 of Fig. 1.

Fig. 5 is a longitudinal sectional View on the plane indicated by line 55 of Fig. 3.

The frame of the device embodies the front and rear longitudinal bars 10 and 11, of angle form in cross section, having their extremities embedded in the masonry at the sides of the fire place opening as indicated at 12, and side bars 13 which are set in between the front and rear bars and are jointed substantially thereto, said side bars also having inturned lower flanges 14: to correspond with the flanges 15 extending in wardly from the front and rear bars for the support of the grate bars 16, of which the upper edges are in a common plane and of which the extremities are enlarged as indicated at 17 to form spacers to provide the necessary ventilating intervals in the body portions of the grate bars.

Depending from the frame thus constructed is an ash pit 18-closed at its front or inner end as indicated in Figs. 1 and 4 andprovided at its rear end with an exten- $1011 19 arranged in a suitable opening formed inthe rear wall of'the fire place and provided at its extremity, outside of the building wall, with a door 20 to give access to theash pit for'the removal of the accumulations therein, said door being provided with an adjustable register 21 so that the draft or ventilation may be varied, at will.

In the event that the fireplace is not provided with a fire brick lining, a metal sheet lining 22 is preferably provided for the protection of the brick work'or other masonry.

It will be obvious that the arrangement indicated provides for the location of the bed of fire on the grate in such a relation to the fire place opening as to afford the maxi mum heat value of the fuel consumed in the room or apartment with which the fire place communicates, and as the draft enters from the rear and the outer side of the building, the air introduced is fresh and does not involve a draft toward the fire place in the room as when the ventilation is from the inside. Moreover, the removability of the ashes and other accumulations in the fireplace from the exterior of the building avoids the disadvantage andinconveniences of bringing this waste material into the' room and carrying it therethrough with the attendant deposit of dust upon the furniture and obviously the down draft through the chimney does not involve the same tendency to throw ashes and burning coals or cinders into the room as when the draft is from the interior as in the ordinary construction. Obviously with. a device as indicated the range of selection of fuel is greatly increased, as coal, and even anthracite and like forms of fuel may be used with advantage and without involving the tendency of having the gas penetrate the room or apartment. As the entrance to the ash pitis located outside of the building, access may be had to the ash pit while an intense fire is burning on the grate without exposing the person to the heat, and also the ash pit may be conveniently and quickly cleaned.

What is claimed is 1. A fireplace grate construction having a frame consisting of longitudinal front and rear bars provided with inwardly directed flanges at their lower edges, side bars joined flanges at their lower edges, grate bars resting upon said front and rear bars and having their ends enlarged to space the main portions of said grate bars from one another and provide ventilating spaces therebetween,

and an ash pit depending from said frame, said ash oit being closed at its inner end and provic ed at its outer end with an extension for penetration of a wall within which the fire place grate is mounted so that the air drafts may be obtained from exteriorly of the building and the contents of the ash pit removed therefrom from the exterior of the building.

2. A fireplace grate construction having a frame consisting of horizontal front and rear bars terminally embedded in the masonry of the side walls of the fireplace opening and side bars jointed to said front and rear bars, the said frame bars being inwardly flanged at their lower edges, grate bars resting at their lower edges upon said inwardly extended flanges of the frame bars and provided with terminal spaced heads or enlargements, and an ash pit depending from the frame, closed at its inner end and provided at its outer end with an extension for penetration of the exterior wall of the building and fitted with a movable door having draft regulating means. a

In testimony whereof I affix my signature in presence of two witnesses.
