Application July 29, 1940, Serial No. 348,191

2 Claims.

The present invention relates to improvements in shovels primarily adapted for removing ashes, clinkers and the like from furnaces.

Since the introduction of the domestic stokerred furnace, the removal of the fire ash and cinders from around the tuyre through the feed door has presented a problem to users of this type of furnace. If ashes were allowed to accumulate on the hearth around the re pot, they would cause excessive clinkering resulting in shutting off proper air supply to the lire bed with a consequent reduction in the efiiciency of the furnace. By means ofthe present invention, removal of ashes and cinders from formerly inaccessible parts of the furnace is readily accomplished.

It is, therefore, an important object of the present invention to provide a shovel constructed in such a manner that removal of ashes, cinders .and the like from inaccessible parts of a furnace can be readily accomplished.

A further object of the invention resides in the provision of a shovel of the above character which permits the removal of ashes, cinders and the like while substantially precluding any disturbance thereof to substantially eliminate dust.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms a part of the application.

In the drawing:

Figure 1 is a fragmentary sectional view of a stoker-red furnace illustrating the use of the improved shovel.

Figure 2 is a vertical sectional view of an ash can and illustrating the manner in which the shovel is used when depositing ashes therein.

Figure 3 is a side elevational View, with parts in section, of the improved shovel.

Figure 4 is a top plan view of the shovel.

Referring to the drawing for a more detailed description thereof, the new and improved shovel is generally designated by the reference numeral 5 and includes a handle 6, the lower end 'I of which is tapered and has attached thereto a metal ferrule 8. A shank 9 is carried by the handle 5, the same being held within a channelv II! formed in the tapered end of said handle.

The shank 9 has attached thereto a concave circular scoop I I, the same being bolted or otherwise secured thereto as indicated at I2. Referring more particularly to Figures 3 and 4 of the drawing, it will 'be noted thatthe intermediate portion .of the shank 9 is slightly curved. as in- Ydicated at I3 and between said curved portion and the scoop II, said shank is formed with a gooseneck I4. The curving of the shank 9 and the forming of the gooseneck I4 supports the metal scoop `II at the proper angle for simplifying the removal of ashes from stoker-fired furnaces. 4

In Figure 1 of the drawing, the shovel is shown in'use for removing ashes from the grate I5 of a furnace I6 receiving its supply of fuel through feeding means I1 from a stoker I8. The shovel 5 is inserted through the door I9 of the furnace and positioned in front yof the lire-box. The twist and gooseneck of the shovel permits the same to reach every part of the fire-box or tuyre and after scraping the ashes or cinders, a slight turn of the handle will position the disc I I so that ashes, cinders and the like can be lifted from the furnace and deposited in a suitable receptacle. In other words, with the shovel in the position shown in Figure 1 of the drawing, movement of the same will push the ashes to the right until the shovel is in a scooping position. 'I'he ashes can then be lifted within the disc II and deposited in a suitable receptacle such as the ash can 2Il illustrated in Figure 2 of the drawing.

If due care is exercised, the shovel can be tipped in such a manner as to dislodge the ashes therefrom into the receptacle 20 without creating dust. It is important, however, that the ash can or receptacle be positioned with the top thereof level with the iire door edge. In this position any gas or dust that may occur will be drawn into the furnace thereby precluding the accumulation of ashes, dust or the like on the outsideof the furnace.

From the above description when taken in connection with the accompanying drawing, it will be readily apparent that there has been provided a shovel having a shank portion formed with an angular bend and gooseneck `turn which will allow the shovel to drop over the edge of the furnace door and straight down to the front of the fire-box for reaching every part of the fire-box so as to readily clean the same of ashes and cinders,

Also it will be understood, of course, by those skilled in the art that variations in the hereinabove described device involving the substitution of substantial equivalents for the devices described are intended to be comprehended within the spirit of the present invention and that the invention is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not aiect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

What is claimed is:

1. In a shoveling device, an elongated handle, a metal shank fastened to and extending longitudinally from one end of the handle, the said shank having a longitudinal curvature and having the outer portion bent laterally of the said l0 longitudinal curvature to form an arcuate portion, the outer end of the shank terminating in a straight extension portion directed at an acute outward angle with reference to the axis of the handle, and a concave circular scoop secured to 145 the outer end of the said shank.

2. In a shoveling device, an elongated handle,

a metal shank fastened to and extending longitudinally from one end of the handle, the said shank having a longitudinal curvature and having the outer portion bent laterally of the said longitudinal curvature to form an arcuate portion, the outer end of the shank terminating in a straight extension portion directed at an `acute outward angle with reference to the axis of the handle, and a concave circular scoop attached to the outer end of the straight shank extension, the said straight extension being disposed axially of the scoop at its concave side and secured to the center of the scoop.
