Specification of Letters Patent.

, Patented June 5, 1917.

Application filed May 23, 1916. Serial No. 99,342.

To all whom gtmay concern.

Be it known that I, JULIUS M. COLLINS, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented certain new and useful Improvements in Ash-Sifters; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention belongs to the class of ash sifters, and has particular reference to a gravity sifter. I

The object of the invention, primarily, is to construct a sifterin which the presence of dust outside of the sifter is practically eliminated. it

Those sifters which are known to me,even those which confine the ashes within a sift ing chamber permit more or less dust to escape at the inlet hopper for the ashes and at the exit spout for the cinders.

The presentinvention avoids the presence of dust both at the inlet hopper and at the outlet spout for the cinders, a specially con structed cover for connecting the ash pail with the hopper being provided and also a special connection between the exit spout and the pail for receiving the sifted material.

My invention further-contemplates a particularly advanta eous arrangement of-gravity screens, whic successively receive the ashes and conduct the siftings to the outlet spouts, and permit the dust or finematerial to drop into a dust receptacle.

With the above and other objects in view, which will hereinafter appear, my inven tion will now be fully set forth and described, reference being had to the accompanying drawing.

In said drawing:- y

Figure l is a front elevation of the sifter,

Fig. 2 is a side elevation thereof,

Fig. 3 is a section on line 33 of Fig. 1,

Fig. 4 is an enlarged detail view of the hopper attachment for holding the ash pail, F Fig. 5 is a rear View of the part shown in Fig. 6 is a detail view of the lower end of the spout, looking from below, and i 1 Fig. 7 is a detail perspective view of the flexible hood used in connection with the invention.

Referring more particularly to said drawings, 1 represents a casing which is constructed of any'suitable material, as metal or wood, and tapers laterallyfrom its lower end to an outward intermediate point, and is then contracted so that its upper end narrows to a receiving opening 2. Within the casing 1 is mounted a plurality of sifting screens 3, 4 and 5. The screens 3 are mounted in angular relation in the upper portionof the casing 1, being carried upon the transverse rods 6 and 7. The rod 6 extends through the machine from front to back and supports the upper ends of the screens 3. From the rod 6, the screens incline in opposite directions to the rod 7 upon which the lower ends of the screens are supported. The screens 3 overlie a chute 8, said chute terminating at its lower end in a conduit 9 which slants toward the rear of the casing l and by means of the bend 10 which passes around the rear end of the screen 5. The screens 4 are secured at their upper ends upon the rods 11 which are carried in the front and rear walls of the easing 1 adjacent the sides 12 at the widest portion of the casing, and converge 1n a downward direction until their lower ends are carried by the bars or rods 13. Ad acent the lower ends of the screen 4, and located on an incline extending from the rear wall of the casing 1 to a lower point through the front wall, is the screen 5, whlchls supported upon the transverse bars 14 and 15. The screen 5 extends into an extens1on'16 formed on the front part of the casing 1 and forms the bottom of the spout 17, which projects forwardly and downwardly from the front of the casing 1.

An annulus cover 18 secured tothe bottom of the casing and extension 16 provides a means for seating the sifting apparatus upon the top of a can, barrel or other receptacle. At the lower end of the spout 17 is provided a semi-circular cover and bracket 19, to whose forward straight side is hinged the cover section .20. The cover section 19 1s downwardly flanged as at 21 and has the free edge of the flange 21 turned inwardly to provide the channel 22. Into said channel, thereinforced edge 23 of the bucket 24 is an, and is therein has by closing the 11d section20 over the bucket, said lid section 20 is also flanged as at 25 to inclose the rim of the bucket. Hinged to the upper end or mouth 2 of the casing 1 is the 'device'for attaching the pail containing the ashes to.

the casing 1. Said device consists of a chute portion 26, which is hinged to the rear edge of the opening or mouth 2 upon the hinges annulus 29 provides a flange support for the rim of a pail 30, the annulus 29 standing in a vertical position, and being adapted to swing slightly beyond its vertical position with. the chute 26 so as to empty the pail of its contents, the cover provided by the annulus having an opening therethrough which corresponds to the section subtended by the rear vertical portion of the chute26. Below the annulus 29, the wall 28 is provided with a pair of hooks 31 which are, in effect, sheet metal plates provided with flanges for attachment to the wall 28, and having the upturned fingers 32 upon which the handle 33 of the pail 30 is adapted to be hooked, in order to lock the pail in position within the annulus 29. tween the cover or annulus 29 and the-chute portion 26, is a door or plate 34: which is hinged at its upper edge substantially in the apex of the chute portion 26 upon the rod 35, so that it can gravitally swing upon .a chute with the motion of the chute portion 26 upon the hinges 27. The hinged brace rods 36 and 37 are connected respectively to the sides of the casing 1, at the upper forward corner, and to the lower forward corners of the sides ofthe chute 26, said rods 36 and 37 acting as stops to limit the rearward swing of the chute 26. The rod 36 is longer than the rod 37 and has its project ing'end overturned as at 38 so that it will "strike against the rod 37 and act as a stop to prevent the rods from having their lon--' gitudinal axes brought into perfect alinement. Surrounding the'mouth 2 and the lower end of the chute 26, is a hood 39, which may be made of foldable metal sections, or may be also constructedof cloth or other suitable flexible material.

the triangularly shaped side pieces 40 and an intermediate section 11, the apexes of the triangular side sections 40 being provided with eyelets 42 which project over the ends of the rod 43' which formsthepintle of the hinges 27. I

In the operation of my improved appa-v Covering the opening be,

When formed of" flexible material, the hood is constructed of ratus, the pail containing ashes to be sifted is mounted in the chute 26, the rim of the pail being projected into the flange 29, and

the handle or bail 33 being engaged with the hooks 31. This engagement having beeneffected, the chute 26 is swung upwardly in a vertical position so that its mouth extends yondv the verticalposition, the door 34: automatically swings open and permits the ashes to drop into the casing 1. 1 The ashes drop upon the screens 3, upon which they are partly sifted, the dust dropping into the chute 8. The cinders and the unsifted material drops then by gravity to the screens 4, and from the screens 4E, the cinders drop tothe screen 5 and pass thence to the spout 17, the dust from the siftings of the screens 41 and 5 dropping into the bottom of the casing 1 and thence into thereceptacle upon which the apparatus is mounted.

From the spout 17 the ashes pass into a bucket which has been mounted upon the combination holder and cover 19, the flange of the bucket being passed into the slideway 21 and being locked therein by the flange'25. of the cover portion, which is swung downwardly to cover the pail. The hood 39 covers the joint between-the chute 26 and the mouth 2, so that all danger of dust escaping from the 1nouth-2 is prevented, so that it is obvious that, bymeans of my improved apparatus one is enabled to sift ashes without the usual attendant dust which escapes even from the best types of, rotary and other sifters which areat present upon the market. 7

What I claim as my invention is 1. An ash sifter-comprising in combination, a casing, a plurality of relatively inelined screens mounted in said casing, said casing having a hopper mouth vand a delivery spout, a chute hinged to said hopper month to drop backwardly therefrom, and

dropped backwardly therefrom, a flexible coveringfor the joint between said chute and said casing, and means for locking a pail to said chute when'thelatter is carried into delivery position.

1. An ash sifter, comprising in combina" tion, a sifter casing, a feed chute hinged to said casing, and means for limiting the relative movement of said chute, means for covering the mouth of a pail and locking the latter into dust-proof connection with the chute, and a gravity cut-off device for pre- Venting the return of dust out of the chute after the pail has been removed.

In testimony whereof, I affix my signature, in the presence of two wltnesses.
