Description

, UNITED STATES PATENT oEEicE. i l JOHN H. AUSTIN, OF CITY, NEVVJERSEY.
I AsH-slFTER.
Specification of Letters Patent.
Patented Oct. 30, 1906. 4
To all whom it may concern:
Be it known that I, JOHN H. AUSTIN, a citizen of the United States, residing at Jersey City, in the county of Hudson and State yof New Jersey, Ahave invented certain new and useful Improvements in Ash-Sifters, -of
which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.
vThis invention relates to sifters for separating ashes from charred coal or small particles of coal which are not consumed; and the object thereof is to provide an improved device of this class which is simple in construction and operation and com aratively inexpensive and by means vof w 'ch ashes may be sifted from charred coal and other substances without the escape of dust from the sifter.
The invention is fully disclosed in the following specication, of which the accompanying drawings form a part, in which the separate parts of my improvement are desi nated .by suitable reference characters 1n each of the views, and in which- Figure l is a central longitudinal "section of my 1m roved ash-sifter and showing the metho of using the same; Fig. 2, a plan view of the sifter, part of the construction being broken away. v
In-the practice of my invention, as shown in Figs. 1 and 2, I provide an oblong box or casing a, the rear end portion of which is open at the bottom, as shown at a2, and the front top portion Ao f which is provided with an opening a3, having a door a4, hinged at 0,5'
and adapted to be folded backwardly, so as to lie on the top of the box or casing c or to be folded forwardly, so as to close the opening a3. Mounted on the front top portion of the casing a is a receiver b, having a sifterbottom b2, composed of wire-cloth, perforated metal, or any other suitable material, and the receiver l) is provided with a rod b3, which passes through thefront end wall of the box or casing a and is provided with a handle b4, by which the receiver b, which constitltes the sifter proper, may be manipulate The bottom b2 of the receiver b is hinged to the front end of said receiver, as shown at b5, and said receiver is mounted on and movable on longitudinally-arranged supports c, whichv secured thereto and betweenl which and the main supports c are vertically-arranged recesses or openings c3, which in the form of construction shown are formed in the main supports c. The bottom b2 of the receiver b is less in transverse width than the main supports c and rests on the supplemental supe ports c2 and is also adapted to rest on rollers d, secured at the rear ends of the supplemental supports c2 when the receiver b 1s moved backwardly of the box or casing a.
The bottom of the front end portion ofthe box or casing a. is also provided with an opening e, which is preferably circular in form and around which is preferably secured a depending collar .or flange e, and arranged within the box or casing a rearwardly of the opening ca is a downwardly and forwardly in'- clined member f, which in the form of construction shown is placed between the rear end portionsl of the supplemental supports c2.
In the operation o f this device the box or casing c, or the frontend portion thereof, is placed over a barrel or other receptacle g, as shown in Fig. 1, which is designed to receive the ashes from the sifter, while the rear end portion thereof is preferably placed over a box or other receptacle g2, designed to receive th charred coal and other substances. The ashes, cinders, and other material are then dumped into the receiver b, the door a4 is closed, and the receiver b is agitated or given a reciprocating motion by moving'the same backwardly and forwardly by means of the rod b3 and the handle b* thereof, and in this operation all the ashes are sifted through the bottom b2 of the receiver b and fall into the barrel or other receptacle g, and when this operation is fully completed the receiver b is forced backwardly into the dposition shownin dotted lines in Fig. 1, an the bottom b2 thereof drops downwardly, as is also shown in dotted lines in Fig. 1, and the charred coal and other substances are dumped into the box or other receptacle g2, and when this is done the receiver b may be pulled back into the position shown in full lines in Fig. 1, and in this operation the bottom b2 thereof strikes on the rollers d and is swung into the closed IOO position and is held in said closed position by the supplemental support c2.
The objectof the vertically-arranged recesses or openings c3, formed in the supports of the recelver b, is to provide means to prevent the accumulation of ashes on said supports, the ashes which would otherwise lodge on said supports being discharged downwardly through the recesses or openings c3.
There is no necessary connection between the sifter or the box or casing a and the barrel or receptacle g and the box or receptacle g2, and any suitable holders or receptacles may be provided for receiving the ashes and charred coal and other similar material.
Having fully described my invention, what I claim as new, and desire to secure by Letof, means for giving said receiver a reciprocating motion and for moving it the length of the box or casing, said receiver being provided with a hinged bottom, and the box or casing being provided with an opening in the bottom of the rear end portion thereof, and means for holding the hinged bottom of tho receiver in a closed position except when it is in the rear end of the box or casing in which position the bottom of the receiver drops downwardly, substantially as shown `and described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 9th day of February, 1906.
JOHN H. AUSTIN.
