JOHN BUSH, 0F JACKSON, MICHIGAN.
DUS'ILESS ASH-SIFTER.
To all whom it may concern Be it known that I, JOHN BUSH, a. citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Dustless Ash-Sifters, of which the following is a specification.
This invention relates to ash sifters, the object in view being to provide a practical device for sifting and screening ashes and separating the coals therefrom for future use, the construction of the device being such that it is practically dustless, the finer particles of the ashes being retained in the receptacle of the sifter, while the coals are discharged therefrom in a clean condition.
1th the above and other objects in view, the invention consists in the construction, combination and arrangement of parts, as will be hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereunto appended.
In the drawings: Figure 1 is a side elevation of an ash sifter embodying the present invention. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a front elevation thereof.
Referring to the drawings, 1 designates a box-like receptacle closed at the top, as shown at 2, and provided with a closed bottom 3, and a hinged door 4 at the front thereof, so as to admit of the insertion and removal of an ash pan or receiver 5 which is normally contained within the receptacle, and under the screening cylinder, hereinafter described. The front wall of the receptacle is provided with a round openiiig surrounded by an outwardly projecting cylindrical neck 6, through which a screening cylinder 7 is insertible and removable. The back wall of the receptacle is extended to form a cylindrical ofiset discharge chamber 8 located outside of the plane of the main body of the receptacle, as shown in Figs. 1 and 2, a discharge spout 9 leading off from the bottom of said offset chamber 8. Furthermore, the offset chamber 8 is situated in a plane below the level of the opening 6, so that the screening cylinder slopes downward toward its rear or discharge end, thereby causing the material to gravitate gradually from the front toward the rear end of said cylinder.
The cylinder 7 comprises a reticulated or perforated body and contains one or more Specification of Letters Patent.
Application filed July 20, 1912.
Patented Jan. 27,1914. Serial No. 710,660.
cross bars or spiders 10, through which a central longitudinal crank shaft 11 passes, said crank shaft being fixedly connected with the cylinder through the medium of said cross bars 10, thereby causing the cylinder to revolve with the crank shaft.
12 designates the hopper which is provided at the top with a hinged cover 13 to prevent the escape of dust and ashes during the sifting operation. At the bottom, the hopper is provided with an elbow 14 inserted in the adjacent end of the screening cylinder 7 and through the neck 6, as shown in Fig. 2, so as to direct the coal and ashes into the cylinder.
The crank shaft 11 extends through a hole in the elbow l4, and is provided at its extremity with a. detachable operating crank 15. Mounted fast on the shaft 11 within the elbow 14 is a spiral feeding conveyor 16 which operates on the ashes passing downward from the main body of the hopper to force the ashes into the cylinder, preventing the'same from lodging and accumulating in the elbow.
From the foregoing description, it will now be understood that after the ashes are placed in the hopper and the hinged cover thereof closed, there is no escape for the dust and ashes, which are fed gradually along the revolving cylindrical screen, the ashes sifting through the openings in the screen and falling into the ash pan, and the coals finding their way out of the open rear end of the cylinder and downward throughthe discharge spout 9.
\Vhile the screening cylinder is supported at its opposite ends by means of the crank shaft 11 having bearings in the elbow 14 and at 17 in the offset chamber 8, the screening cylinder may be readily removed from the receptacle for cleaning purposes, whenever necessary. When the ash pan 5 be comes filled, it may be withdrawn from the receptacle, emptied and restored to its normal position.
lVhenever necessary the screen 7 may be renewed by detaching the hand crank 15 from the shaft 11 which enables the screen together with its shaft to be removed from the casing and also from the elbow at the bottom of the hopper. In this way the cylindrical screen may be bent back to its original shape in case it should become dented or injured. Furthermore the screen may be removed from the elbow and a new one substituted therefor after which the detach able crank 15 is replaced on the end of the shaft and fastened thereby holding the screen and its shaft and the elbow in their proper relative positions for insertion in and removal from the receptacle.
\Vha-t is claimed is:
An ash sifter comprising a receptacle, an inclined hollow cylindrical neck extending outwardly from one end thereof, a hopper, an elbow at the bottom of said hopper reniovably inserted through said neck and projecting into said receptacle, an inclined rotary screening cylinder having one end encircling a-nd journaled on said elbow and removable therewith through said neck, a straight shaft for rotating said screening cylinder journaled in said elbow and removable together with the soreening cylinder, elbow and hopper, and a crank on the hopper end of said shaft.
In testimony whereof I affix my signature in presence of two Witnesses.
JOHN BUSH.
