ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 545,094, dated August 27, 1895.

Application tiled March ZO, 1895.

To ctZZ whom, t may concern:

Be it known that I, JOHN G. P. PUTNAM, a citizen of the United States, residing at Claremont, in the countyof Sullivan and State of New Hampshire, have invented a new and useful Ash-Sifter, of which the following is a specification. v

The invention relatesto improvements in ash-sitters.

The object of the present invention is to improve the construction of sitters, and to provide a simple and inexpensive one adapted for rapidly and conveniently sifting ashes and other material, and capable of enabling the sifted material to be readily discharged from the rotary cylindrical sieve.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure l is an elevation ot' an ash-sifter constructed in accordance with this invention.- Fig. 2 is a vertical sectional view taken longitudinally of the cylindrical sieve. Fig. 3 is a similar view taken transversely of the cylindrical sieve. Fig. 4 is a detail perspective view of aportion of the cylindrical sieve, showing one of the catches. Fig. 5 is an enlarged detail sectional View of one of the catches.

Like numerals of reference indicate eorrespending parts in all the tigures of the drawings.

l designates a sitter, comprising a casing 2 and a rotary cylindrical sieve 3, removably journaled in the casing. The casing is composed of a lower body portion and a semicylindrical cover 4, removably mounted on the body portion. The body portion is rectangular, and is provided at the base with a cylindrical cap 5, adapted to t over the open end of a barrel, whereby the sitter is mounted thereon. The rotary cylindrical sieve has a periphery of wire-netting, or the like, and comprises a body portion 6 and a segmental section or lid 7, which is hinged at one side at S to the body portion 6. The body portion is provided at its ends with catches for holding the lid or hinged section 7 closed, and each catch comprises a slotted Serial No. 542,529. (No model.)

resilient plate 9 for engaging a lug l0 of the hinged section or lid, and a projecting supporting-plate 11, arranged adjacent to the resilient plate 9. exterior or outer face of the end of the lid or hinged section, and the resilient plate 9 is also located on the outer face of the end of the body portion of the sieve, and the free end of the plate 9 is curved or bent outward. The plate 11 is located on the inner face of the end of the body portion of the sieve and has its upper or outer end bent in- Ward, and the oppositely-bent upper ends of the plates 9 and l1 form a tlaring mouth or entrance to the space between the plates. The end of the hinged .section or lid is re ceived between the plates 9 and 11, the bent ends of the latter forming a flaring mouth to receive the lid or hinged section, and the plate l1 prevents any accidental disengagement of the lug. The slot l2 of the plate 9 extends longitudinally of the same, and the lug l0 is beveled to enable it to force the spring-plate outward in order to engage the slot thereof. The lid or hinged section may be readily swung open by forcing the springplate outward suiiicient to release the lugs 10. The journals of the cylindrical sieve are preterably formed by a shaft 14, fixed to the body portion of the sieve and having one of its ends extended and formed into a crank-han die located on the exterior ofl the casing.

The lug is arranged on thev It will be `seen that the sitter is simple and i comparatively inexpensive in construction, that it is adapted for operating on all kinds of'rnaterial, and that the catches for holding the sections of the cylindrical sieve closed are strong and durable and are readily manipulated. y

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle .or sacrificing any of the advantages ot this .in-

vention.

In a sitter, the combination of a casing, a cylindrical sieve journaled therein and provided with a hinged section or lid, and catches located at each end of the cylindrical sieve and each comprising a resilient plate mounted on the exterior of the body portion of the IGO sieve and provided with a slot and having its upper free end curved outward, a supporting plate mounted on the interior of the body portion and arranged adjacent to the resilient plate, and having its upper end curved inward, and co-operating with the outwardly curved end of the resilient plate to form a iiaring mouth or entrance to the space between the plates and a lug mounted on the ro exterior of the lid or hinged section 'and having a beveled portion and engaging the slot of the plate, substantially as described.

In testimony that I claim the foregoing as my own I have hereto axed my signature in the presence of two witnesses.
