6 Claims'." (01. 12s--242) A further object of the invention is to provide a device hinged to the lower margin'of the ash pit door opening, adapted to swing'upwardly to close the opening, and with amember hinged to said swinging member, which will, in use, lie along the floor, said member provided with an opening registering with an underlying receptacle.

A further object of the invention is to provide a closure for an ash pit door, having a hinge, and a member hinged to'said hinged member and adapted to fold simultaneously with theclosing of the ash pit closure.

A furtherobject of the invention is to provide a devicewhich will be associated with an ash pit door providing in its own organization a closure for the door opening and a hinged extension, with an opening for registering with an underlying receptacle, both closure and extension being provided with upstanding flanges for re straining the ash in its coursefrom the ash pit to the receptacle. I

The invention, therefore, comprises a platelike member which will combine with a furnace or other heating plant, in such manner as to close the ash pit door opening when swung to the upward position, and to form an outwardly extending apron when swung downwardly from closing position, with a second member hinged to the swinging member and provided with an opening for registering with an underlying receptacle, and with a flange carried by the extension member adapted to cooperate with the door closing member to form a passageway from the ash pit door to the receptacle wholly surrounded by an upstanding flange.

The drawings illustrate several embodiments of the invention and the views therein are as follows:

Figure 1 is a view in perspective of one embodiment of the invention shown in open position, adapted to conduct ashes from the pit door to a depressed receptacle,

Figure 2 is a view in edge elevation of the device swung to close the ash pit door,

Figure 3 is a sectional view through the device, showing its relation to the underlying well,

Figure 4 is a view in edge elevation of a slight- 1y different modification, shown in open position, and indicating its manner of closing the door, and

Figure 5 is a still different modification shown in edge elevation and in dotted lines indoor closing position.

-Like characters of reference indicate corre-- sponding parts throughout the several views.

Heating plants, such for instance, as domestic t'ypes'of boilers, are mounted in various ways. In some instances they are set above the floor level on a platform erected for the purpose and as indicated at 10 in Figures 1, 2, 3 and 4. These platforms may vary in height and in the drawings two different heights have been indicated. In other instances, the heating unit which will be referred to as a furnace 11, is set directly upon the floor level, as indicated in Figure 5.

' In the application of the device to the furnace, the ash pit door is removed. The opening for the ash pit door is almost invariably surrounded by a bead 12 and a plate 13 is provided of such size as to close this opening. The plate is applied by means of clips 14 mounted upon opposite sides of thebead of the opening to which the plate is hinged. The plate is hinged in any aprovecl manner, as'by the rod 15 passing directly under the lower run 'of the bead 12.

As this plate 13- is thus hinged to a position under the bead, it will prevent the passage of ash between the bead and the plate. In the several types wherein the furnace is mounted upon a platform, as shown at 10, the plate will be inclined downwardly to the floor level, such inclination depending upon'the height of the platform 10.

In the type shown at Figure 5 there is slight, if any, inclination. To the edge of the plate 13, which is outermost, a second plate 16 is hinged, as by the hinges 1'7, and is provided with an opening 18 of such dimension as to cooperate with a receptacle placed in an underlying well shown in Figure 3. Preferably, this opening 18 will be surrounded by a downturned flange 20 so that the flange, approximately fitting the underlying receptacle, will prevent the escape of ash.

The plate 13 is provided with a tongue 21 which, in extended position as shown at Figures 1 and 3, overlaps the edge of the plate 16, and thereby prevents the escape of ash.

About three sides of the plate 16 a flange is erected comprising the end flanges 22 and 23, and the side flange 24. The end flanges 22 and 23 are extended beyond the edge of the plate 16 opposite the flange 24. These extensions are shown at 25 and 26. The extensions 25 and 26 are provided with inturned flanges 27 and prefoperation is identical.

the plate 16 extending at an inclination down wardly and may, in fact, serve as a means for holding the plate 13 in closed position over the.

opening.

When being raised along a path indicated by the dotted line, the side flanges 25 and 26 will move upwardly along the front of the furnace to the position shown at Figure'2.

In opening, the hinge 17 will traverse the dotted lines shown at Figure 2 until the position shown at Figures 1, 3 and 4 has been attained. 1

In the type shown at Figure 5, the flanges 23' are hinged at 29, as is also the plate with the opening; Thus constructed, the hinge 1'7 may move on the dotted line, as shown, and by retaining the hinge 29 at or about upon the floor level, the extension .25 will move upwardly to the position shown inv dotted lines as 25".

The hinge 29 is made necessary forthe reason that the outwardly extending part must fold to the position shown in dotted lines, .so that the flange 23, which is in this modification straight instead of bent, may extend upwardly along the furnace front, as indicated.

This type is operated exactly as the type shown in the other figures, and with the exception of the hinge formed in the side flanges22' and 23', and the connecting plate, the construction and Of course the ash handling device herein illustrated may bemodified and changed in various Ways without departing from the invention herein setforth and hereafter claimed.

. The inventioniis hereby claimed as follows:

1; An ash handling device adapted to be associated with a furnace having an ash pit opening, comprising a plate provided with a hinge adapted forconnection with the furnace and to underly the opening of the ash pit, a second plate hinged to the first mentioned plate and provided with an opening therethrough for register with an underlying receptacle, and an upstanding flange embracing both of said plates.

2. An ash handling device, comprising a plate having a hingeal'ong both edges, a second plate hinged to the first mentioned plate at one of said hinges, said second plate being provided with an opening having a downturned flange, and a flange carried by the second mentioned plate extending over and cooperating with the edges of the first mentioned plate.

3. The combination with a furnace having in a vertical wall an ash pit opening surrounded by a bead, of a road fixed beneath thelowermost reach of the bead, a plate hinged to the rod and extending outwardly and proportioned to swing upwardly to close the opening, a second plate hinged to by a'bead, said device comprising a rod fixed beneath the lower reach of the bead, a plate hinged to the rod and proportioned to swing upwardly to closethe opening, a second plate hinged to the first mentioned plate and adaptedto swing down: wardly as the first mentioned plate swings up wardly, said second mentioned platebeingprovided with an opening therethrough proportioned to register with an underlying receptacle, and a flange surrounding the plateswhen in theex tended positions. 7 5. In combination with a furnace having an ash pit opening surrounded by a bead, a plate hinged beneath the lowermost reach of the bead andadapted to swing upwardly to closing position over said opening and outwardly away from such closing position, a second plate hingedto the edge of the first mentioned plate opposite the,

hinging to the furnace, said second mentioned plate being provided with .an ash discharge opening, and a flange carried bythe second mentioned plate having extensions beyond the lines of said plate cooperating with the edges of the firstrnen tioned plate.

. 6. The combination with a furnace having an ash pit opening surrounded by a head, a plate hinged beneath the 'bead and adapted to swing upwardly to closing position over said opening and outwardly away. from closing position, a sec- 0nd plate hinged to the first mentioned plate, flanges upstanding from the second mentioned plate and extending overand cooperating with the edges of the first mentioned plate, said second mentioned plate and flanges thereon being hinged to form coacting sections.
