ers, of which the following is a specification.

This invention relates to new and useful improvements in ash sifters.

4The primary object of the invention is the provision of a device serviceable for household use whereby ashes may be sifted by a clean and sanitary method, the combustible contents being easily separated for use.

A further object of the device is the provision of an ash sifter having a neat appearance and being easily operated While preventing the escape ofdirt and dust during the sifting operation, the partially burnt coal being readily removed for reburning.

A still further object of the device is the provision of an ash sifter having two parts which may be readily separated, lthe device being cheap and easy to manufacture lfrom sheet metal and being highly efficient in its operation and non-combustible in structure.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

1n the drawings forming a part of this application and in which Vlike designatingV characters refer to corresponding parts throughout the several views Figure 1 is a central vertical sectional view throughthe device as positioned dur ing the sifting operation.

Fig. 2 is a front elevation thereof.

Fig. 3 is a view similar to Fig. 1 with the elements normally arranged and with the ash tray partially removed, the bail thereof being shown elevated in dotted lines.

Fig. 4 is a perspective Vview of a forward corner portion of the device with the slide door partly opened.

Fig. 5 is a vertical transverse sectional view of the device taken upon a plane at right angles to the plane of section of Fig. 1, the sieve being shown partially tilted by dotted lines.

Fig. 6 is a horizontal sectional view taken upon line VI-VI of Fig. 3.

Fig. 7 is an enlarged detail sectional view of a' rear portion of the sieve member inclosing the receiving tray therein, and

Fig; S is a detail sectional view taken upon line VIH-V111 of Fig. 3.

rlhe present device being specially designed for household use in the operation of sifting mixed ashes and cinders for the purpose of separating the same to allow the cinders so cleaned to be employed for burning, a clust-proof substantially cubical casing 10 -isemployed for containing the operative mechanism hereinafter set forth and adapted to prevent the escape of ashes and dirt during the sifting operation. A

A pan shaped sieve or sifting member 11 is revolubly mounted upon a horizontal axis within the casing 10 by means of a shaft 12 secured longitudinally of the bottom 13 of the said sieve and'having its inner end 14 journaled in aperforation 15 in the rear ayall 16 of the said casing while the forward end of the shaft 12 rests in a central socket 17 in the lo-wer edge 1S of a door opening 19 in the forward side 2() of the said casing. A slide door 21 .is arranged for the said door opening-19 and has a cooperating socket 22 in its lower edge for overlying the shaft 12,

Y whereby the sockets 17 and 22, each of which is substantially semicircular, form a journal bearing for the said forward end of the sieve shaft 12. A. hand operating lever 2?) is pivoted as at 24 to the outer free end of the shaft 12, the said lever being retained in its normally lowered position by means of a U-shaped spring clip 25 mounted adjacent the bottom of the front wall 12 and centrally thereof. The sieve 11 hasa foraminous cov- A ering 26 upon the side thereof opposite its bottom 13 while the forward end of the said sieve is normally opened adapted for the sliding reception of a receiving tray 27 of substantially the same configuration as the sieve 11 but `of slightly less dimensions, it being understood that the said tray is open at the top thereof being provided with an edge bead 28 which is positioned adjacent the sieve covering 26 when the tray is operatively arranged within the sieve, as best illustrated in Fig. 7 of the drawings.

A. swinging bail 29 is carried by the tray 27 having its free end slightly bent for overlying the forward edge of the said tray when the bail is in its inoperative position which allows such free end to wedgingly' engage the forward edge of the sieve covering 26 for assisting to retain the tray within the sieve. Stop washers 30 are carried by the shaft 12 adjacent its opposite ends for bearing against the rear and front walls of the casing l0 when the sieve is arranged therein, while it will be understood that when the device is normally positioned as shown in Fig. 3 ofthe drawings, the door 21 may be opened by means of its handle 31 for allowing the tray 27 to be withdrawn from the sieve by means of the bail 29 for emptying the cinders from the tray and refilling the same with einders and ashes. The tray is then re-positioned in the sieve ll by sliding the same therein and upon lowering the top 2l7 the lever 23 is detached from the clip 25 and upon being released, the sieve ll reverses its position by reason of its own weight with the foraminous covering 26 arranged downwardly and whereupon lateral impulses imparted to the lever 23 results in sifting the ashes from the t'ay 27 through the sieve covering 2G and .into the ash box 32 at the bottom of the easing l0.

The said ash box 32 is slidably arranged upon the casing bottom and has a handhold knob 34: whereby the box is readily removed for emptying the ashes therefrom and then reinserted in the casing for further use during the sifting operation. fr handle 35 is pivoted to the top of the easing whereby the entire device may be readily carried whenever desired.

It will thus be apparent that a handy device for readily sifting ashes is arranged 1,21s,eeo

presenting an unobjeetionable appearance and preventing the escape of any material during the sifting operation, it being noted that substantially the entire structure is formed of sheet metal, the device being absolutely fire-proof.

llVhile the form of 5^the invention herein shown and described is what is believed to be the preferable embodiment thereof, it is nevertheless to be understood that minor changes may be made in theform, proportion and details of construction without de` parting from the spirit and scope of the invention as hereinafter claimed.

lllhat I claim as new is An ash-sifter, including a sieve having a foraminous covering, said sieve'having fixed centrally to its bottom, a shaft journaled in position for reversing the sieve bottom-upward as in presenting the sieve-covering downwardly in performing the sifting operation,` said shaft having pivotally eonnested to one end thereof a handle, means forthe retention of said. handle in position as against the casual rotation of said shaft, and a tray insertible within said sieifeTone end of the latter being open therefor, said tray having' pivotally Connected thereto a bail. having its free end bent for overlying the forward edge of said tray and wedgingly engage the forward edge of the sieve to provide for aiding the retention -of the tray within the sieve.

In testimony whereof I aiiix my signature.
