STANLEY J. TOBIASZ, OF CHICAGO, ILLINOIS.

ASH-SIFTER.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed Matr 13, 1907. Serial No. 373,281.

To all whom it may concern:

Be it known that I, STANLEY J. ToBIAsZ, a subject ot the Emperor of Austria-Hungary, residing at Chicago, in the county ot Cook and State ot Illinois, have invented certain new and usetul Improvements in Ash-Sitters, oi which the following is a specification.

The object ot the invention is to provide an ash sitter so inclosed as to prevent the escape ot dust or dirt and at the same time enable the ready insertion oi raw ashes and the removal ot the sitted ashes and coals.

The invention consists in the features ot construction and combination ot parts hereinaiter described and claimed.

In the drawings, Figure 1 is a trent elevation of the ash box showing the door removed; Fig. 2 a sectional elevation showing the side ot the sitter box; and Fig. 3 a perspective view ot the sitter box.

The ash box, as a whole, is in the iorm ot a rectangular box 4, having side walls 5, a rear Wall 6, a root 7, and a front cross wall 8. The cross wall is ot a size to provide an upper opening, closed by means ot a hinged door 9, and a lower opening into which is entered a drawer 10. Immediately above the drawer the walls ot the ash box are provided witha strip ot metal 11, in the torm ot a chute adapted to divert the sittings into the drawer. Within the ash box is located a rotatable sitter box 12 comprising sides 13, each ot which has a curved upper portion 14, and between the curved upper edges ot the side walls ot the box is stretched a screen 15. The rear end ot the screen is secured to a cross rail 16, and the tront portion ot the screen is in the torm of a door 17 secured to the main portion by means of rings or hinges 18. The lower iront edge ot the door portion is secured to a door cross rail 19, which, when the door is closed, is immediately above and in alinement with a xed tront cross rail 20, to which the door section is secured by means ot a hook 21. In addition to the tront and rear cross rails the sides are secured together by means ot cross sills 22 extending across the bottom ot the box; and inside ot the side walls and extending trom end to end ot the spotter box are downwardly sloping inner side walls 23, the lower edges ot which rest upon the cross sills 22, and these inner side walls serve the double purpose ot bracing the main side walls and also providing a socket tor the reception ot a tapered pan 24, the formation ot which permits it to be wedged tightly in place between the sloping inner side walls. The sitter box is mounted on trunnions 25 and 26 which extend through the side walls ot the ash box, and the trunnion 26 is extended and has secured thereto a handle 27 which permits the sitter box to be rotated.

In use, when it is desired to sift a quantity ot ashes,

the hinged door 9 ot the outer sitter box is opened, and thereafter the hinged screen door 17 is interlocked and litted back, which permits a pan ot ashes to be inserted into the interior ot the sitter box and wedged in place between the sloping or converging side walls 23. Atter the screen door has been fastened down and the main door ot the ash box closed, the sitting operation is pertormed by turning the handle and rotating the sitter box. This operation serves to agitate the ashes, and

with every revolution the tine particles and dust are dropped through the screen, the unburned coals remaining within the pan ot the sitter box. After the sitting operation is completed, the pan can be removed, and likewise the lower drawer 10, which contains the Sittings, can be removed and emptied in preparation tor turther operations.

The invention is one which permits the easy insertion ot ashes carried in a pan and undisturbed prior to the closing ot the ash box door. This obviates the creation ot dust incident to ordinary ash sitters in which the ashes are dumped out ot a pan or back into the sitter prior to the closing ot the same. In the present instance, no disturbance is created until the ashes are iinally deposited in position to be sitted and the door shut. At the same time the same pan which serves tor the transportation ot the unsitted ashes will serve tor the carrying ot the reclaimed coals, which renders the operation simple, easy and unattended by any objectionable tea-tures.

What I regard as new and desire to secure by Letters Patent is:

l. In an ash box, the combination of an inclosing box provided with a door, and a rotatably mounted sifting box comprising flat side walls provided with curved upper edges, a screen connecting said curved upper edges, cross connections for the bottom and ends of the fiat side walls of the box, downwardly sloping inner side walls constituting braces between the outer side walls and the bottom cross connections, and an ash pan having downwardly converging side walls adapted to be wedged into place between tlie inner sloping side Walls, and a handle for rev0lving Athe sitter box, substantially as described.

2. In an ash box, the combination of an inclosing box provided with a door, and a rotatably mounted sifting box comprising flat side walls provided with curved upper edges, a screen connecting said curved upper edges, a portion of said screen being hinged to provide a door, cross connections for the bottom and ends of the lat side walls of the box, downwardly sloping inner side walls constituting braces between the outer side walls and the bottom cross connections, and an ash pan having downwardly Converging side walls adapted to be wedged into place between the inner sloping side walls, and a handle for revolving the sitter box, substantially as described.
