ASH-SIFTER.

SPECIFICATION forming part Of Letters Patent NO. 558,170, dated April 14, 1896.. Application filed November 18, 1895. Serial No. 569,303. (No model.)

is to improve upon the construction of this class of ash-sifters, as now ordinarily made, and to provide an ash-sifter of very simple construction and operation; and my invention consists in certain novel features of construction and operation of my ash-sifter, as will be hereinafter fully described, and the nature thereof indicated by the claims.

I have shown in the drawings my ash-sifter as an individual sifter placed on the top of a barrel or can; but it is adapted and intended to be used with an ash-chute extending two or more stories on a building, and each story having an ash-sifter, combined with the ashchute.

Referring to the drawings, Figure 1 is a front perspective view of my ash-sifter placed on the top of a barrel. Fig. 2 is a vertical section through the front of the sifter on line 2 2, Fig. 3, looking in the direction of arrow a, same figure, the partition 23 shown in Fig. 3 being removed; and-Fig. 3 is a central ver tical section through the ash-sifter, taken on line 3 3, Fig. 1, looking in the direction of arrow 1), same figure.

In the accompanying drawings, 1 is the top of a barrel or can, and 2 is the ash-sifter, provided in this instance with a fiat circular base 2, adapted to fit over the top of the barrel to hold the ash-sifter thereon.

The ash-sifter 2 consists of a receiver or box 3, preferably of the shape shown in the drawings, having fiat sides and top and a flat rear end, and its front end flat at its upper part and of curved or convex shape in crosssection and slanting backwardly at its lower part.

The receiver or box 3 is made open at its lower part or end to allow of the discharge of the ashes into the barrel 1 or into the chute with which said receiver or box 3 may be combined.

The top of the box 3 is provided with a hinged cover 4 at its front part, to be raised, as shown in Fig. 3, to pour the ashes into the sifter, and then closed, as shown in Fig. 1, to prevent any dust from getting out of the box. The top of the box 3 may also be provided with a slide 5, which extends over an opening 6 in the top of the box, at the rear part thereof. Through the opening 6 clinkers can be thrown to fall on the rotary sifter and pass into the barrel through the lower open end of the box 3.

The lower front part of the box 3 is provided with a delivery-chute 7, leading directly out of the lower front part of the box, through which the coal passes from the rotary sifter into a hod or other receptacle, which may be hung on a hook 8, secured on the top of said discharge-chute 7.

WVithin the receiver or box 3 is arranged the sifting mechanism, which consists of a rotary sifter 9, preferably made of wire-netting, and mounted on a shaft 10 to turn with said shaft. The shaft 10 is journaled in bearings 11 and 12 in the rear and front ends of the box 3, and is provided with a handle 10, extending upon the outside of the box 3, at the front part thereof, to turn said shaft.

The shaft 10 does not extend in a horizontal plane, but is preferably inclined toward the lower front part of the box, so that the rotary sifter 9, which is of the same diameter throughout its length, will be inclined toward the front or discharging end of the sifter, as shown in Fig. 3. The sifter 9 is made open at its front end and is provided with two or more arms 13, extending inwardly and downwardly to a hub 14, which is secured on the shaft 10 by a set-screw 15. The hub 14:, in connection with the arms 13, serves to support the front end of the sifter 9 and hold it in its proper position relative to the shaft 10.

The rear closed end of the sifter 9 is supported on the shaft 10 by said shaft extending through a hole in said end. A bar 16 extends horizontally through the box or receiver 3 just in front of the sifter9 and is secured at its ends 16 to the sides of said box. A sleeve or bushing 17, mounted on the shaft 10 between the hub 16 on the bar 16 and the hub 14:, in connection with a pin 18, extending through the shaft 10 directly in front of the hub 16, serves to prevent any longitudinal motion of said shaft 10.

Instead of a pin 18, a collar or other equivalent device may be secured to the shaft 10 in front of the bar 16 to prevent any longitudinal motion of said shaft.

A door or damper 19 is hung or pivotally supported by means of lugs 19, extending into grooves or slots in blocks 20, secured to the sides of the box 3, (see Fig. 2,) directly in front of the lower half of the open end of the sifter 9, and acts to close the lower half of said open end of the sifter to prevent any discharge through the same.

One of the lugs 19 is elongated and extends through one side of the box 3, (see Figs. 1 and 2,) and is provided with a handle 21, by means of which the damper or door 19 may be raised, as shown by dotted lines in Fig. 3, to allow the discharge of the coal after the same has been sifted from the sifter through the discharge-chute 7. In this instance the inner end of the handle 21 extends through a hole in the lug 19, so that said handle may be moved out or in at its free end, which is adapted to extend under a catch 22, secured;

to the side of the box 3 (see Fig. 1) to hold the damper or door 19 closed while the sifter 9 is being rotated.

Extending through the upper part of the box 3 is an inclined transverse partition 23, (see Fig. 3,) which is supported in the front part of the box and shuts oil": the upper front part of the box 3 from the lower front part thereof, and through the lower front part of the box extends a transverse partition 24, leading from the lower front end of the sifter 9 to the discharge chute 7. The partition 23 is made curved or concave in cross-section, so that when the coal is poured into the top of the box 3, the hinged cover 4 being raised, it will be discharged into the rotary sifter 9 through the upper part of the open end thereof. The partition 24: at the lower part of the box 3 is also made curved or of concave shape, as shown in Fig. 2, to cause the coal, &c., to be discharged out of the lower part of the open end of the sifter into the discharge-chute 7 when the damper or door 19 is open, as shown by dotted lines, Fig. 3.

From the above description, in connection with the drawings, the operation of my sifter will be readily understood by those skilled in the art.

WVhen it is desired to use the sifter, the cover 4 is raised. The ashes poured into the top of the box 3 will fall on the partition 23 and be discharged into the rotary sifter 9, the door or damper 19 having been first closed and held closed by means of the catch 22.

The rotary sifter 9 is now revolved by means of the handle 10 on the shaft 10 and the sifted ashes are discharged from said sifter through the open bottom of the box 3 into the barrel or other receptacle 1. After the ashes have been sifted sufficiently the damper or door 19 is opened by means of the handle 21 and the sifter 9 is again revolved. The inclination of the sifter 9 will cause the coal or clinkers therein to be discharged onto the partition 24 and through the chute 7 into a hod or receptacle hung on the hook 8. In case there are any clinkers in the coal the same will be picked out and thrown through the opening 6 in the top of the box 3 and will fall onto the sifter 9 and into the barrel 1.

The advantages of my ash-sifter will be readily appreciated by those skilled in the art. It is of very simple construction and operation, and is not likely to get out of order. During the operation of sifting, the dust, &c. is prevented from getting out of the box or receiver.

It will be understood that the details of construction of some of the parts of my ashsifter may be varied, if desired, and, as above stated, the same may be combined with an ash-chute.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of a box or casing, having an inclined transverse partition in the upper front portion, and an inclined trans verse partition in the lower front portion, a rotary sifter mounted therein and having a closed inner end, and a door pivotally supported at its upper edge and closing the lower half of the discharge end of the sifter, and a handle for moving the same, and a catch with which said handle engages, to hold the door closed, substantially as set forth.
