ASH SIIETER.

Application filed. October 6, 1921.

To all whom it may concern:

Be it known that I, Hona'rro S. EAaLn, a citizen ot the United States, residing at Detroit, county ot -i' i aync, State ot Michigan, have invented a certain new and useful Improvement in Ash Sitters and declare the tollowing to be a tull clear, and exact description ot the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings which torn). a part ot this specification.

This invention relates to ash sitters and the object ot the invention is to provide an ash sitter which is ot cheap construction and which is very eficient in operation. Another object ot the invention is to provide an ash sitter which is pivotally mounted in a trame work, the said sitter being rocked on its pivot to sift the ashes therein. A turther object ot the invention is to provide a cylindrical casing pivotally mounted in a frame work. the said casing being divided longitudinally by a screen on which the ashes are positioned, the casing being'rocked on its pivot to sitt the ashes, the sifted ashes being delivered from the lower halt ot the casing and the large particles which do not pass through the screen being delivered from the upper halt ot the casing. These objects and the several novel features ot the inven tion are hereinafter more fully described and claimed and the preterred torm ot construction by which these objects are attained is shown in the accompanying drawings in which-- Fig. 1 is a side elevation of an ash sitter embodying my invention.

Fig. 2 is an end elevation thereot.

Fig. 8 is a section taken on line 33 of Fig. 1.

The device consists of a cylindrical sheet metal casing 1 having a stud 2 extending outwardly from each side thereof as indicated more particularly in Fig. 2. Each stud 2 is mounted in a bearing member 3 having a shank 4 which is riveted in position between the legs 5 ot the trame. A cross member 6 is provided connecting the legs 5 adjacent the lower end thereof and a metal trame member 7 shown more particularly in Fig. 2 connects the two members 6 and also acts as a stop which prevents complete rotation of the cylinder 1 on its pivot. A cover member is provided tor the end ot the cylinder comprising two Serial No. 505,?61.

halves shown at the lett of Fig. 1. the lower halt 8 being secured to the end of the cylinder 1 and the upper halt 9 being hinged to the portion 8 by a hinge 10. Both cover portions 8 and 9 are provided with a flange fitting about the endot the cylinder 1 and a spring catch 11 is secured to the cylinder 1 by rivets 12, the said catch being adapted to hold the cover portion 9 closed when the ashes are being sitted. A wire screen 13 extends longitudinally through the cylinder and divides the cylinder into an upper chamber 14 and a lower chamber 15 as shown more particularly in Fig. 3. This screen 13 is provided with a series of cross bars 16 which tot-m part ot the screen and are riveted to the opposite sides ot the cylinder 1 at 17. A cover member 18 is provided tor the end ot the cylinder at the right of Fig. 1- which is divided into two parts, the upper part 18 being flanged and secured to the cylinder 1 to close the end of the chamber 14 and the lower part 19 being provided with a flange and hinged to the upper part 18 at 20. the part 19 torming a door tor the lower chamber 15. A spring catch 21 is proi-ided which is similar to the spring catch 11 and is secured to the casing 1 by rivets 22, the catch 21 being adapted to hold the portion 19 closed during operation of the device and. a pair ot hand holds 23 and 24 are provided whereby the cylinder may be rocked on its pivot.

n operation the ashes to be sitted are thrown through the door 9 into the chamber 14 onto the screen 13 at which time both doors 9 and 19 are closed and held closed by the spring catches 11, and 21. The operator then by grasping the hand holds 23 and 24 oscillates or rocks the cylinder on its pivot and causes the ashes to travel back and forth over the screen 18 which sitts the same, the fine ashes falling through the screen into the chamber 15. l/Vhen the ashes have been sitted. the operator turns the device on its pivot so that the door 19 is in its lower-most position at which time the spring catch 21 may be released thus allowing the door 19 to open and deliver the sitted ashes into a receptacle placed therebeneath to receive the same. The door 19 is then closed and the cvlinder is tilted so that the door 9 is in its lower-most position at which time the spring catch 11 may be released to allow the door9 to open and deliver the coals and large pieces remaining on the screen 13 to a receptacle provided for receiving the same. If desired both doors may be placed at one end of the cylinder, in which case, the opposite end would be pro vided with a cover permanently secured thereto, but it will be found somewhat easier to deliver the sifted ashes and the coals when the doors therefor are placed at opposite ends of the cylinder.

From the foregoing description, it becomes evident that the device is very simple and eflicient in operation will not get out of order, is composed of few parts and is of consequent low manufacturing cost and provides a device which accomplishes the objects described,

Having thus fully described my invention, its utility and mode of operation what I claim and desire to secure by Letters Patentof the United States is 1. An ash sifter consisting of a framework including two spaced standards, a bearing at the upper end of each standard, a cylindrical body member position between the said standards, studs positioned centrally on opposite sides of the cylindrical member and engaging the bearings, a screen extending longitudinally of the cylindrical member separating the same into two compartments, a closure member for each end of the cylindrical body member consisting of a fixed and a hinged part, the fixed part of one closure member being above the screen at one end and below the screen at the opposite end, the said cover members having hinged portions likewise respectively disposed.

2. An ash sitter consisting of a framework having spaced upright portions, 'a body member of cylindrical form positioned between the spaced frame portions and pivotally supported thereby, a screen extending longitudinally of the cylindrical member dividing the same into two equal compartments. a closure member for each end of the cylindrical members, each closure member consisting of two half parts one of which is fixed to the end portion and the other of which is hinged to the said fixed portion, the hinge line being in the plane or the screen and the fixed part of the one cover member atone end being below the screen and at the opposite end being above the screens and with the hinged portions likewise oppositely disposed, and a handhold near each end of the body member.

In testimony whereof, I sign this specification.

HORATIO S. EARLE.
