To all whom-it'mag co izcem Be itknown that LLEE V. Emma citizen of the United States, residing at Vaynesburg, i'n-th'e county of Greene and State of Pennsylvaniadmve invented certain new and useful Improvements in Trash-Feed Attachments for Furnaces, of which the following is a specification.

This invention relates to an improvement in trash-feed attachments for furnaces, being directed particularly to a. chute-like member which may be conveniently applied to the fuel receiving opening of the furnace, and held in position through its particular construction and cooperation with the furnace parts; the device when in position serving to permit the convenient delivery of trash or other refuse to the fire bed.

The construction is in the nature of a chute, with the side walls extended and so formed as to have a bearing relation with fixed parts of the furnace, to thereby hold the attachment in place without fastening or particular adjustment, and permit its instant removal when not desired for use.

The usual feeding of trash or the like to a furnace requires removal of such trash from the trash receptacle by hand and its delivery to the furnace in piecemeal. This is not only objectionable through liability of scattering, but is dangerous through possibility of With the improved attachment, it is only necessary to insert the end of the same into the door opening, when the parts'interfit with the furnace parts. and the structure is held in a proper position to receive the trash and deliver the same onto the fuel bed without waste of time, scattering of the refuse, or danger of fire.

The invention is illustrated in the accompanying drawings, in which Fig. 1 is a broken sectional view of a furnace with the attachment in place.

Fig. 2 is a perspective view of the attachment.

The attachment is here shown as applied ing for the application and holding of the attachment.

The attachment proper is preferably,

though not necessarily, constructed of a single sheet of material, as sheet iron, and is formed to provide sides 7, a bottom 8, and a narrow rear wall 9. The sides 7 extend forwardly beyond the forward edge of the bottom. and converge slightly from the receiving toward the delivery end. That is the chute portion of the attachment is slightly wider at the outer end than at the end with in the furnace. The extended portions of the sides 7 are rounded on their forward edges, and their upper forward edges are cut away or recessed at 10, to enable this portion of the attachment to enter the opening 3, and to provide means for rocking the smoke deflector which is usually employed in furnaces of this type out of the way. This formation of the sides 7. produces a point-like extremity of each upper edge at 11, adapted when the device is in applied position to bear against the upper wall of the fuel way. The bottom 8 of the attachment is of such length that when in position it will rest on the lower wall 6 of the fuel way, and consequently the attachment is held in position by being wedged in place between the points of the sides 7 and the bottom 8. In other words the distance between these two bearing points. when the attachment is in position. is greater than the distance between the upper and lower bearing surfaces 5 and 6 of the furnace, thus causing wec 2- ing action. The proportions of these formed ends of the attachment, will serve to hold the chute portion at a downward inclination in. the direction of feed, so that trash delivered into the open portion of the attachment is delivered onto the fuel way and so to the fuel bed.

It is to be particularly noted that no particular means are provided for holding the attachment in place. as the mere insertion of the same properly into the fuel opening of the furnace. will arrange the parts described, and the attachment will be held by its lower bearing on the wall 6 and its upper bearing against the wall 5. Under these circumstances, the attachment can be readily applied and removed by anyone, and no especial care is necessary in either operation. The attachment is entirely of metal, and the trash when placed therein will gravitate rapidly to the fuel way, and be delivered onto the fuel bed, Without possibility of scattering or danger of fire.

Having thus described the invention, what is claimed as new, is

1. A trash feeding attachment for furnaces, comprising a body, having a bottom and side walls, the side walls extending in one direction beyond the bottom and being rounded from the forward edge of the bottom to the upper extremities of said walls, said upper extremities of the side walls and forward edge of the bottom providing bearing points to cooperate with furnace walls for holding the attachment in position.

2. A trash feeding attachment for furnaces, comprising a body having side walls, a bottom connecting the side walls and terminating at one end rearwardly of the forward ends'of the side Walls, said forward ends of the side walls being upwardly rounded from points in line with the termination of the bottom, said rounded edges of the sidewalls terminating in points in advance of said terminal edge of the bottom to provide bearing points for supporting 25 the attachment in position.

In testimony whereof I afiix my signature.

LEE V. KENT.
