ASH-SIFTER.

Specification of Letters Patent.

Patented Mar. 17, 1914:.

Application filed November 27, 1912. Serial No. 733,732.

To all whom it may concern:

Be it known that I, PATRICK Connor, a citizen of the United States, residing at Philadelphia, count-y of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Ash-Sifters, of which the following is a full, clear, and ex act description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to that class of ashsifters in which an agitatable screen is mounted in a box.

The object of my invention is to so construct the sifter that the ashes and cinders may be introduced to the screen, the sifting operation performed and the ashes and cinders separately removed with the production of a minimum of dust.

In the accompanying drawings: Figure 1 is a plan view of my improved ash sifter; Fig. 2 a front elevation; Fig. 3 a partial end view; Fig. 4 a horizontal section on line H of Fig. 2; Fig. 5 a vertical-section on line 5-5 of Fig. 4c; and Fig. 6 a partial section on line 6-6 of Fig. 4:.

The sifter box a is mounted on legs I) which rest on the floor. The sifter box is provided with a top opening 0, over which rests a receiver or storage box cl having a hinged cover 6. Into the receiver is directly deposited the cinders and ashes taken from the ash pit of the heater or furnace. The receiver at is provided with a removable sliding bottom f, which normally closes communication between the receiver and the sifter box. The receiver (Z is shown as removable. If desired the cover 6 may be made integral with the receiver, and the receiver may be filled after first inverting it and sliding back the bottom f. The bottom f may be then closed and the receiver may I then be again inverted anddeposited in position over the sifter box. If, however, the cover 6 is hinged, the receiver may remain permanently in position over the sifter box a, and the ashes and cinders placed in the receiver while in that position. Extending within, and between the ends of, the sifter box a, and about midway between the top and bottom thereof, are two horizontal supporting bars 9, upon which loosely rests the screen or sifter h. The ash box is also provided with an opening a in the upper part of one side thereof. To the lower edge of this opening is hinged a door j which, when closed, forms virtually part of that side of the box. The door may be retained in its closed position by means of any suitable latch, as 70. The door j is provided with a vertical slot Z, and a similar vertical slot at is formed in the opposite side of the box.

lThe screen 72, is provided with arms a, n,

which extend respectively through the slots Z and m. On the arm n projecting through the slot Z is formed the handle 0.

The screen it may be agitated by grasping the handle 0 and rocking the screen back and forth on its supporting bars 9', the screen being guided in its movements by the bars rt, 77., in the slots Z and m. I have also provided the following means for agitating the screen h, which may be employed in case it is not desired to agitate the screen by direct manipulation of one of the bars 11.. Extend ing between the sides of the sifter box a, immediately below the hinged door j, is a shaft 10, one end of which projects through one side of the box and has the crank g by means ofwhich the shaft may be turned.

The shaft is provided with the oppositely disposed cams 1, which, as the shaft is rotated, alternately engage the bottom of the screen It, one side of the screen being engaged by one cam and the other side of the screen being engaged by the other cam. This produces a rocking motion of the screen similar to that produced by direct manipulation of one of the bars a.

The sifter box a is provided with a sliding removable bottom .3. Underneath the bottoms, and preferably fairly closely fitting the sifter box but not attached thereto, is a discharge receptacle 2?, which, when the bottom 8 is removed, receives the ashes which have passed through the meshes of the screen.

In the end of the box, preferably near the bottom, is a relatively small opening a,

which is adapted to be closed by a door 4) but it may be briefly outlined as follows: The hot ashes and cinders from the' ash pit are placed in thereceiver (Z in either of the ways hereinbefore described. The receiver is preferably made of suflicient size to hold several days supply. When it is desired to sift the ashes and cinders, the bottom 6 of the receiver (Z is slid out to the extent required, dependent upon whether it is desired to sieve all, or only a part, of the ashes and cinders in the receiver cl. The ashes and cinders thereupon drop into the siftcr it. At this time the doors 7' and e and the removable bottom .9 are closed. The Sifter may then be agitated by either of the means hereinbefore described, which causes the ashes to fall onto the removable bottom 8, while the cinders remain in the sifter h. The above operation is, if necessary, repeated, until all the material is sifted. The removable bottom .9 is then slid out and the ashes resting thereon drop into the discharge receptacle or ash-box 2,. After the removable bottom 8 has again been closed and the dust within the sifter box a has settled down, the door j may be lifted, and the sifter 7t containing the separated cinders, may be removed. The foregoing operation is practically a dustless one. Further, the cinders are not discharged into an exterior receptacle; but being scattered over the bottom of the screen, the clinkers may be readily picked out by hand.

Having now fully described my invendesire to protect by 1 ing to permit the removal of the screen, and

a door closing said opening.

2. In an ash sifter, the combination with a sifter box having an opening to receive the cinders and ashes, of a-screen supported within the box so as to be free to rock, there being an opening in the upper part of one side, a hinged door for the opening, there being a slot in the door and a corresponding slot in the side of the box opposite the door, and arms on the screen projecting respectively through said slots, thereby. permitting the screen to be rocked and also allowing the door to open to permit the removal of the screen. v

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 23rd day of November, 1912.
