ASH-SIFTEB.

Application filed January 4, 1913.

To all whom it may concern:

Be it known that 1, WILLIAM A. BEVARD, a citizen of the United States, residing at Washington, in the District of Columbia, have invented new and useful Improvements in Ash-Sifters, of which the following is a specification.

This invention relates to certain new and useful improvements in ash sifters and the primary object of the invention is to provide a device of this type which enables the sifting operation to be easily and quickly performed without the presence of dust and which also has novel means for enabling separation of the dust and ashes from the cinders upon completion of the sifting op eration.

in the drawings: Figure 1 is a perspective view of the invention; Fig. 2- is a longitudinal vertical section; Fig. 3 is a section on the line 33 of Fig. 2; and Fig. 4 is a central transverse section taken through the sifter box.

The sifter consists of a substantially rectangular box 1 which has a hinged cover 2 secured in closed position by any suitable fastener 3. Secured on the interior of the box 1 and above the bottom thereof is a preferably concave screen 1 which separates the box into an upper cinder compartment 5 and a lower ash and dust compartment 6. A hinged door 7 is provided at one end of the box which door communicates with the cindercompartment 5 and is held closed by a suitable fastener 8. A similar hinged door 9 is provided at the opposite end of the box, the door 9 communicating with the ash compartment'6 and being held closed by a suitable fastener 10. A trunnion 11 is secured to each side of the box, the trunnions being disposed centrally of the length of the box and seating in bearings 12 provided on the upper ends of vertical side arms 13 that are secured to a supporting structure 1 1. The supporting structure is herein illustrated as comprising vertical end walls 15, a back 16, a bottom 17 and a central partition 18 which divides the structure into a cinder receiving chamber 19 and an ash dust receiving chamber 20. The chamber 19 may be provided with a depending and rearwardly inclined apron 21 which serves to retain the cinders within the chamber, the lower end of the Specification of Letters Patent.

apron being spaced from the bottom 17 to allow the cinders to be shoveled out of said chamber. Plates 22 are secured at the top of the supporting structure and serve to restrict the downward movements of the ends of the box during the rocking movements of the box. Deflector plates 23 are secured at the ends of the supporting structure and act to deflect the cinders, or ashes clownwardly into their respective chambers when the contents of the box are being emptied. A handle 24 is secured to one end of the box in order to allow of manual rocking thereof.

In operation the ashes are placed in the compartment 5 of the box, the lid closed and fastened and the box rocked from the full line position depicted in Fig. 2 to the dotted line position shown in said figure. Upon completion of the sifting operation, the box is moved to bring the end having door 9 over the compartment 20 whereupon said door is opened and the ashes and dust thereby permitted to gravitate into said compartment, and if desired a can C may be placed in said compartment to receive the ashes and dust. The box is then rocked to cause the end thereof having door 7 to overlie the compartment 19, whereupon the door 7 is opened and the cinders permitted to gravitate into the compartment 19.

From the above it will be apparent that the cinders, and ashes and dust, are discharged from opposite ends of the box which allows the separation to be effected quickly and easily and since the entire sifting of the ashes takes place in a closed airtight box, no dust can possibly escape from said box.

What is claimed is:

In an ash sifter, a supporting frame having a downwardly and inwardly inclined deflector plate at each end thereof, stops arranged adjacent and in spaced relation to the deflector plates, a sifter box pivoted between its ends so that the latter will engage the stops to limit the extent of downward movement of the box, said box having upper and lower compartments and having an outlet at each end for the respective compartments, and a door for each outlet hingedly connected at its top side to the box adjacent the top side of the outlet whereby when the box ends are engaged with either In testimony whereof I have hereunto set my handin presence of two subscribing witnesses.
