WILLIAM T. LAMM, OF BUFFALO, NEW YORK.

ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 696,056, dated March 25, 1902.

I Application filed July 6, 1901- Serial No. 67,328. (IlomodeL) T aZZ whom it may concern.- I

Be it known that LWILLIAM T. LAMM, a ci tizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Ash-Sifter, of which the following is a specification.

This invention is an improved ash-Sifter, the object being to provide a simple and practicable construction of ash-sitter by means of which the dust and dirt can be quickly and. easily separated from the cinders and the said cinders withdrawn from the sifter for the purpose of being reburned.

With this object in view the invention consists in the peculiar constructionof the various parts and in their novel combination or arrangement, all of which will be fully described hereinafter and pointed out in the claim.

In the drawings forming part of this speci fication, Figure 1 is a vertical sectional view of an ash-sifter constructed in accordance with my invention. Fig. 2 is a side elevation of the upper section, the top being removed. Fig. 3 is a detail perspective view of the sieve. Fig. 4 is a detail view illustrating the relative position of the two screens.

In the practical embodiment of my invention I employ a lower section or receptacle A, which is preferably made of sheet metal strengthened by means of beading-grooves; but it will be distinctly understood that this lower section or receptacle may be made of any desired material and infact may be an ordinary barrel. Fitted into the'upper end of this lower section or receptacle is a cylindrical case B, the lower end of which is adapted to fit into the upper end of the lower section, and a bead B limits the inward movement of the said case. 0 indicates the top or cover, which is fitted into the upper end of the case B. A Wire screen D is arranged within the case B adjacent to its lower end, said screen being inclined, as indicated, its lower side being arranged adjacent to an opening E, produced in the side of the case, said opening being normally closed by means of a door F, which slides in the guideways F, secured upon the exterior of the case B. A circular sieve G is arranged within the case B adjacent to its upper end, said sieve having a rod H extending rearwardly from its frame, said rod being round in cross-section through its entire length. A rod I projects forwardly from the opposite side of the frame of the sieve, that portion of the rod adjacent to-the frame being round in cross-section, while the portion 1 adjacent to the handle K is square in cross-section. The rod I extends through a horizontal slot 1*, produced in the side of the case, and the square portion I normally rests in the said slot, a coil-spring L being arranged around the rod I between the frame of the sieve and theinner side of the case, thereby serving to hold the square portion of the rod in the slot 1 and securelymaintain the sieve in a horizontal position.

In operation the ashes'to be sifted are placed in the sieve G, the cover 0 of course being removed for the purpose of introducing the ashes, and the said cover is then'replaced. The door F is also closed. The sieve G is then vibrated or moved rapidly back and forth by means of the handle K, and the ashes or fine dust and dirt will pass through the sieve and also through the screen D down into the bottom receptacle A. The vibrating operation of the sieve is continued until all the ashes or fine dust has been separated from the cinders, and the cinders remaining in the sieve are dumped upon the screen D by turning the said sieve upon the rods H and I, it being understood that the handle is drawn out to disengage the square portion I from the slot I and bring the round portion of the shaft into the said slot, thereby permitting the sieve to be rotated upon therods H and I as an axis. The cinders so discharged upon the screen D will gravitate to th lower side of the same, and by opening the door F the said cinders can be quickly and easily removed from the sifter.

It will thus be seen thatI provide an exceedingly simple device by means of which the ashes and cinders are quickly separated, and

mit the front rod to be pulled out to remove 10 the square portion from the slot for the purpose of rotating the sieve, substantially as set forth.

\VILLIAM T. LAMM.
