ASH-SIFTER.

SPECIFICATION forming part of Letters Patent No. 569,745, dated October 20, 1896.

Application filed March 14, 1896. Serial No. 583,163. (No model.)

To aZZ whom it may concern Be it known that we, J only B. CHADBORN and EDWARD ANDnovErT, citizens of the United States, and residents of Newburg, in the county of Orange and State of New York, have invented certain new and useful Improvements in Ash-Sifters, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which similar letters of reference indicate corresponding parts.

This invention relates to what are known as ash-sifters; and the object thereof is to provide an improved device of this class whereby the cinders, portions of charred coal, coke, and other products may be quickly and easily separated from the ashes of a furnace, stove, or grate, a further object being to provide a device of this class which is novel in construction and operation, and which con-. sists of a suitable casing, in which is mounted a revoluble cylindrical screen, which is also of novel construction, and into which the ashes, together with the charred coal, the cinders, and other products are placed 5 and with these and other objects in View the invention consists in the construction combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a transverse section of Fig. Fig. 2, a side view of our improved ash-sitter with part of one side thereof broken away, and Fig. 3 a plan view.

In the practice of our invention we provide a casin g the central portion of which is cylindrical in form, as shown at A, and said oylindrical portion is arranged longitudinally of the casing and about the middle thereof, and below said cylindrical portion is a rectangular base B, in the bottom of which is mounted a drawer b, and above the cylindrical portion the casing is also rectangular in form, as shown at D, and the ends 0 and E are vertical and parallel, as shown in Fig. 2.

The rectangular top D of the casing, which is open, is provided with a door G, and secured adjacent to the top D are the arms 7t; of a spring-frame K, which is composed of strong spring-wire bent into a rectangular or square form, and which is placed over the opening in the top D, which is similar in form, and which is adapted to be held in the position shown in Fig. 1 by a spring-catch L, which operates in connection therewith, as shown at I YVhen the wire frame K is held in the position shown .in Figs. 1 and 3, the door G. will extend inwardly and downwardly, as shown in said Fig. 1, and it will be observed that the arms 70 of the spring-frame K are passed through the back of the top of the casin g at 7.3

Mounted in the cylindrical portion A of the casing is a convolute screen M, which is composed of wire-mesh or any preferred and similar material, and which is provided with circular end pieces m, through which passes a shaft m one end of which is provided with a crank m, by which the screen is revolved.

One side of the screen M is secured to the end pieces near the outer edge thereof, as shown at m in Fig. 1, and said screen is carried around said end pieces about threequarters of the circumference thereof, and then bent inwardly, as shown at m and the door G is adapted to rest upon this inwardlyourved port-ion m of the screen.

In operation the ashes, oinders, charred coal, coke, and other substances are poured into the screen through the opening in the top of the casing and, striking upon the door G, slide downwardly into the convolute screen and the door G is then raised by the frame K, so as to close the opening in the top of the casing, in which operation the frame K is thrown backwardly, and the door G is held in the closed position by the spring-catch L, which is provided with an inwardly-directed shoulder or projection L for this purpose.

The screen-cylinder is then revolved in the direction of the arrow a, (shown in Fig. 1,)

and in this operation, as will be understood,

ashes are sifted therethrough into the drawer b, and the cinders, charred coal, coke, and similar products or articles remain in the screen. hen the ashes are all sifted out in the above-described operation, the drawer Z) is emptied and replaced, after which the screen is revolved in the opposite direction, and in this operation all the cinders, charred coal, COliO, and similar articles will be discharged or emptied into the drawer b and may then be removed therefrom. This operation is rendered possible by reason of the form of the convolute screen M and the manner in which it is connected with the circular end pieces on and the open space m between the separate sides of the screen, and whenever it is desired to place more ashes within the screen the spring-frame K is again lowered into the position shown in Fig. 1, in which position the door G drops downwardly and again rests upon the inclined sides m of the convolute screen.

Our improved sifter may be used for sifting flour and other articles as well as ashes; and this device is simple in construction and operation and is perfectlyadapted to accomplish the result for which it is intended, and it is evident that changes in and modifications of the construction herein described may be made without departing from the spirit of our invention or sacrificing its advantages, and we reserve the right to make all such alterations therein and modifications thereof as fairly come within the scope of the invention.

Having fully described our invention, we claim as new and desire to secure by Letters Patent 1. In a sifter the combination of a casing provided with a circular portion, a bottom portion provided with a removable drawer and a top portion having an opening therein, said cylindrical casing being provided with a convolute sifter which is mounted therein, directly beneath said opening and which is composed of a cylindrical screen connected with cireularcnd pieces, one side of the screen being connected to the end pieces at or adjacent to the perimeter thereof and being carried partially around the same and the opposite side being inwardly curved and the upper portion of said casing being provided with a downwardly-moving door adapted to close the opening and also to be held in a downwardly-inclined position so that it rests upon the inwardly-curved side of the screen and means for holding said door closed, substantially as described.

2. In an ash-sifter, the combination of a casing provided with a circularor cylindrical portion, a bottom portion provided with a removable drawer, and a top portion provided with an opening, said cylindrical casing being provided with a convolute sifter which is mounted therein directly under the feed-opening, and which is composed of a convolute screen connected with circular end pieces, one side of the screen being secured to the end pieces at, or adjacent to the per imeters thereof, and being carried partially around the same, and the opposite side being inwardly curved and said upper portion being provided with a door which is adapted to close the opening therein, and also to be held in a downwardly-inclined position, so that it rests upon the inwardly-curved side of the screen, and said door being supported by a rectangular spring-frame which surrounds the opening in the top of the casing, and which is provided with arms which extend therethrough, to which the door is secured, substantially as shown and described.

3. In an ash-sifter, the combination of a casin g provided with acircular or cylindrical portion, a bottom portion provided with a removable drawer and a top portion provided with an opening, said cylindrical casing being provided with a convolute sifter which is mounted therein and which is composed of a convolute screen connected with circular end pieces, one side of the screen being secured to the end pieces at, or adjacent to the perimeters thereof, and being carried partially around the same, and the opposite side being inwardly curved and said upper portion being provided with a door which is adapted to close the opening therein, and also to be held in a downwardly-inclined position so that it rests upon the inwardlycurved side of the screen, and said door being supported by a rectangular spring-frame which surrounds the opening in the top of the casing, and which is provided with arms which extend therethrough, to which the door is secured, and said convolute screen being provided with a shaft which extends therethrough, and through the casing and which is provided at one side with acrank by which it is revolved, substantially as shown and described.
