ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 415,622, dated November 19, 1889.

Application filed January 22, 1889. Serial No. 297,140. (No model.)

To a whom it may concern.-

Be it known that I, JOHN DILLON, a citizen of the United States, residing at the city, county, and State of New York, have invented certain new and useful Improvements in Ash- Sifters, of which the following is a specification.

This invention relates to an improved ashsifter by which the unburned coal particles can be separated effectively from the ashes without causing any dust, so that the sifting of the ashes can be accomplished in the kitchen or at any other convenient place; and the invention consists of certain improvements in ash-sitters, as will be fully described hereinafter, and finally pointed out in the claim.

In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved ash-sifter on line a; .r, Fig. Fig. 2 is a vertical transverse section of the same on line 1 1 Fig. 1. Figs. 3 and 4 are detail vertical transverse sections of the ashchutes below the first or upper screen of the ash-sifter on line f f, Fig. 1; and Fig. 5 is a detail top view of a portion of the ashchutes below the upper screen.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents an ash-sifter, which is made in the shape of an oblong box, and which is supported in upright position on a baseboard a. The top of the box A has at one edge a hinged lid A, which is provided at bothsides with segmental guardwalls A that form, when the lid A is in open position, a kind of hopper for facilitating the transfer of the ashes from the ash-pail to the sifter. The sheet-metal side guard-walls A of the lid A also serve, when the lid is closed, to prevent the escape of dust from the sifter. From the upper edge of that end Wall of the sifter A where the lid A is arranged extends in downward direction an inclined screen B. Below the screen B are arranged two adjacent V-shaped ash-chutes 0, provided at their lower ends with deflecting-plates O, divergent laterally from the adjacent edges and forming, with the outer side walls, lateral dischargeopenings C The ashes are shed laterally in opposite directions by the chutes onto a second diagonally-inclined screen D, that extends below the upper coarser-meshed screen B in opposite direction to the same from a point near the top of the sifter to a point near the bottom of the same, as shown clearly in Fig. l.

Above the screen B is arranged a pendent gate B, which is hinged to the top of the sifter A near the lid A, and which is moved out of the way by the ashes when they are dumped into the sifter and dropped back, so as to form contact with the screen B when the ash es have passed the screen B beyond the gate B. This gate B serves to diminish greatly the escape of dust from the sifter immediately after dumping and before the lid A can be closed. The unburned coal particles pass over the inclined coarser screen B onto the diagonal finer screen D, between the two streams of ashesdischarged laterally from thechutes C, and are collected at the lower part of the sifter near one end wall of the same, which end wall is provided near the screen D with a discharge-opening d and a slide d, so that the unburned coal can be removed into a box or pail whenever it is desired to remove the same. The ashes which are passed through the screen B are first shed by the laterally-inclined chutes 0 onto the diagonal screen D and dropped through the same into a receiving ash-pan E at the bottom of the sifter A. For the purpose of distribute ing the ashes uniformly in the box E, a second chute F is arranged at the middle part of the sifter below the diagonal screen D and at right angles thereto, which serves for conveying a portion of the ashes to the opposite end of the ash-box E, so that they are not deposited all at the same end of the box E.

The interior surface of the walls of the sifter above the diagonal screen D, as well as the lid and gate, are lined with sheet metal, so that the glowing cinders cannot injure the box. The lower part of the sifter below the screen D requires no lining.

The ash-pan E is removed through an opening 6 in the opposite end wall of the sifter, which is also provided with a slide 6' for closing said opening, so that the sifter can be used in the kitchen or at any other convenient place for sifting the ashes. hen not in use as a side of said diagonal screen at right angles thereto, and an ash-pan at the bottom of said box.

In testimony that I claim the foregoing as 15 my invention I have signed my name in presence of two subscribing Witnesses.

JOHN DILLON.
