ASH-SIFTER.

Specification of Letters Patent.

Patented Nov. .20, 1905.

Application filed Apr-i118, 1906. Seria1-N0.312.380.

To all whom it may concern.-

Be it known that I, JAMES J. WEIR, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Ash-Sifters, of which. the following is a specification.

One object of my invention is to so construct a combined ash scoop and sifter that the ashes can be readily collected therein from the ash-pit of a stove or furnace and can then be sifted without the escape of dust, the coal and fine ashes being separately dis charged from the device into different receptacles.

It is further desired that the device shall be of cheap and simple construction and shall possess no parts which are likely to be injured or rendered inoperative by the rough treatment to which a device of this character is ordinarily subjected.

These objects I attain as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of a combined ash scoop and sifter constructed in accordance with my invention. Fig. 2 is a longitudinal section of the device illustrated in Fig. 1. Fig. 3 is a sectional plan view, and Fig. .4 is a sectional view illustrating a modification of one of the features of my invent1on.

In the above drawings the main casing 1 of the device is in the form of a scoop, with a closed to 2 and an inclined front door or flap 3, suitab y hinged by a transverse rod to lugs 4 on the top of the scoop at the front end of the same. By preference the front door 8 is flanged at each end, as shown at 5, the flanges overlapping the sides of the scoop, so as to aid in forming dust-proof joints at such points.

The door 3 has at the top an upstanding lug 6, which when engaged by a pivoted turnbuckle 7 on the top of the scoop will serve to retain the door 3 in a closed position. When the turnbuckle is thrown back out of the way, however, the door 3 can be raised and thrown back onto the top of the scoop, the lug 6 in such case passing through a slot 8 in the top of the scoop.

To the rear of the scoop, adjacent to the top of the same, is secured a clip 9, and to this clip some distance below the top of the scoop is pivoted the rear portion of a sifter-plate 10, the front end of which rests uponthe bottom of the scoop, adjacent to the front edge thereof, being normally retained in this position by the engagement of a lug 11 on the sifter-plate with a turnbuckle 12, pivoted to the bottom of the scoop near its front edge. The scoop has at the rear a socket 13 for the reception of a handle 14, whereby said scoop can be readily manipulated.

In operation the front door or flap 3 of the scoop is thrown back over the top thereof, and the scoop is then used to take up the ashes in the ordinary way, the sifter-plate being in its normal position, as shown in Fig. 2. The door 3 is then closed and locked by engagement of the turnbuckle 7 with the lug 6, after which the scoop is shaken, so as to cause the finer portions to pass through the perforations of the sifter-plate into the chamber below the latter. This operation can be effected without the escape of dust from the scoop, because of the close fit of the door to the front portion of said scoop. When the sifting operation has been completed, the door 3 is released and the coal is dumped from the sifter-plate into a suitable receptacle, after which the latch 12 is turned so as to release the front edge of the sifter-plate, and thus permit of the discharge of the ashes from,beneath the same into another receptacle. Instead of using the latch 12 the sifter-plate 10 may, if desired, be provided at its upper end with a thumb-piece, as shown at 15 in Fig. 4:, constructed to pass through a slot in the top of the scoop near the rear end thereof, so that by pressure of the thumb or finger against said piece when the coal is being discharged from the scoop the sifter-plate may be retained in its normal position, with its front edge in contact with the bottom of the scoop, in order to prevent the escape of the ashes with the coal, the release of pressure from the thumb-piece permitting the rise means whereby its front end can be normally closed top, a pivoted and inclined sifterretained in contact with the bottom of the plate, with a hinged front door or flap having I 5 scoop, substantially as specified. a lug thereon, and a pivoted latch on the top 2. The combination of a scoop having a of the scoop for engagement with said lug in closed top and a movable front door or flap, order to hold said front door or flap in its an inclined sifter-plate pivoted at its upper closed position, substantially as specified. and rear end to the rear of the scoop and In testimony whereof I have signed my 20 resting at its lower forward end against the name tothis specification in the presence of bottom of the scoop, with a latching device two subscribing witnesses. for normally retaining said lower front end of g JAMES J.
