NEWTON BENJAMIN, OF ELMIRA, NEW YORK.

ASH-SIFTER.

Application filed February 7, 1912.

To all whom it may concern:

Be it known that I, NEWTON BENJAMIN, of Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Ash-Sifters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in that class of ash sifters which are adapted to rest on the top of an ash can or other receptacle, the object being to provide means whereby the dust arising from dumping the ashes into the sifter and from sifting the ashes, will be confined within the device.

A. further object is to provide a simple and inexpensive device, particularly adapt ed for domestic purposes, and which will be easy to operate, and which provides for a complete separation and recovery of the unburned coal from the ashes.

WVith these objects in View, my invention consists in the details of construction as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure l is a view in perspective of my device. Fig. 2 is a view in vertical section of same. Fig. 3 is a view in horizontal section through the part carrying the screen, the latter being shown in its horizontal position, and Fig. 4 is a similar view showing the screen in its turned position.

My device comprises two detachable sections 1 and 2 adapted to be used with a third section 3, which may be the ordinary ash can, barrel, or other reeeptacle'adapted to receive the ashes separated from the unburned coal. The upper section 1 consists of a cylindrical body, and a top 4, a portion 5 of which is horizontal, and the major part thereof 6 inclined as shown, and provided with a circular opening surrounded by an outwardly flaring funnel shaped rim 7 forming a hopper. Hinged to the underside of the inclined portion 6 of the top section, is the counterweighted door or closure 8 which latter conforms to the shape of the opening in the top section 1, but is of greater diameter than said opening, so that when closed it will effectually prevent the escape of dust from the receptacle. This door or closure 8, is provided with an arm 9 which projects upwardly over the rim 7 at the hinge side Specification of Letters Patent.

of the door 8, and then outwardly, and is of a weight suflicient to hold the door up in its closed position. The lower end of the section 1 is open and is provided above its lower edge with an externally projecting bead 10 adapted to rest on the top of section 2, when the lower end of section 1 is telesco-ped with the upper end of section 1. This section 2 is open at its upper and lower ends and is provided at a point above its lower end with an outwardly projecting head 11 adapted to engage and rest on the upper end of section 3, which as previously explained may be an ash can, barrel or other receptacle to receive ashes. Mounted in oblong horizontal slots 12 and 13 in section 2, is the shaft 14 carrying the screen 15. This screen is circular in shape, and conforms in size to the internal diameter of section 2, and is centrally secured to the shaft 14, which latter has a movement lengthwise the slots so as to effect a shaking movement of the screen, and also has a rotary movement whereby the screen may be turned to a ver tical position in order to dump any unburned coal resting thereon. In order to prevent the escape of dust through the slots 12 and 13, the shaft 14 is provided with cover plates which latter are mounted in guides and move with the shaft, and are of suflicient length to cover the slots 12 and 18 throughout the full shaking movement of the shaft.

Extending half way around the inner section 2, in the plane of the lower edge of the slots 12 and 13 is the shelf 17 on which the screen 15 normally rests. This shelf extends from one end of one slot around to the farther end of the other slot, so that the shelf is under one slot but not under the other. lVhen the shaft 14 is located at the ends of the slots adjacent the ends of the shelf, it may be tilted to turn the screen for dumping the unburned coal thereon, but when the shaft is shifted laterally in the slots 12 and 13, so as to project over the shelf, the latter engages the screen on both sides of the shaft, and locks the latter against rotary or tilting movement. This shelf instead of being continuous may be cut away at intervals, as shown, so as to permit any ashes or dust settling thereon to be removed by the shaking movement of the screen.

The section 2 is provided with handles 18 by which it and the section 1 thereon may be lifted into position onto section 3, and by which it is handled when removed from section 1.

To operate the device the ashes are shov- I claim as new and desire to secure by Lett ers-Patent, is

1'. As a new article of manufacture, an ash siftercomprising-a receptacle, a shelf in said receptacle and extending approximately eled or dumped onto the door 8, and as the latter is sensitive, it gives under the weight and permits the ashes todrop onto the screen, and instantly closes, thus confiningthe dust created or freed from the ashes,- within-thereceptacle. By now moving, the shaft back. and forth in the elongated slots, the finer particles will pass through thescreen into, receptacle 8, thus leaving, the larger ones on thescreen. By now removingsectionQ withsection 1, thereonfrom section 3, thelunburned coalon thescreen can be dumped by'simply tilting thev screen or,

if; desired the top section may be removed and the contents of the sieve dumped, or.

poured out. without tilting the screen.

\Vith thisimprovement, which: is, exceed-- ingly simple in construction and inexpen siveto make, it will beseen that ashes can be handled and thoroughly screened with out creating any dust, and, by. making, the

device in sections theparts can be conveniently and readily handledi.

Itisevident that changes in-theconstruction and relative arrangement of the several parts. might be made without avoiding-only invent-ion and; hence I would have itaunderstood that I' do not restrict myself" to the particular construction and arrangement of partsshown and described, but,
