ASH-SIFTER.

Specification of Letters Patent. P t t d 30, 1919,

Application filed April as, 1918. Serial No. 230,329. t

To all whom it may concern:

Be it known that I, WI LIAM C. ANDER- SON, a citizen of the United States, residing at Brunswick, in the county of Glynn and State of Georgia, have invented certain new and useful Improvements in Ash- Sifters; and I do hereby declare the following to 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.

My invention relates to improvements in ash sifters, and broadly and generally speaking it consists of a casing fully open at its upper side, a cover removably mounted upon the open side of the casing, a cradle or crank shaft pivoted within the easing, a Sifter located within the casing and removably mounted upon the cradle or crankshaft, and a handle connected to the sifter and extending through the front end of the cover.

One object of the invention is the pro vision of an ash sifter of the above stated character wherein the cover shall be so connected to the casing as to effectively prevent the escape of dust therefrom dur'ing the sifting operation.

Another object of the invention 1s the provision of an ash sifter of the above stated character which shall include means adapted to permit the sifter to be tilted upwardly above and upon the casing through the medium of the handle when it is desired to discharge the cinders from the sifter.

A further object of the invention is the provision of an ash sifter of the above stated character which shall include means by which the sifter may be easily and quickly placed in proper position upon the cradle or crank shaft.

A still further object of the invention is the provision of an ash sifter of the above stated character wherein the cradle or crank shaft shall be removably mounted in the casing and wherein the handle may be folded against the sifter, so that these parts may be assembled in a compact manner upon the bottom of the casing when it is desired to store or ship the ash sifter, and so that these parts may be readily removed when it is desired to remove the ashes from the casing.

Vith the above and other objects in view, the invention consists in the construction, combination and arrangement of partshereinafter fully described and claimed, and

illustrated in the accompanying drawings,

wherein: p a t Figure 1 is a perspective view of an ash sifter constructed in accordance with myinvention. M

Fig. 2 is a sectional View taken on a vertical plane extending centrally and longitudinally through the ash Sifter.

Fig. 3 is a sectional view taken on a vertical plane extendina centrally and trans PS i versely through the ash sifter.

Fig. 4 is a perspective view of a fragmentary portion of one of the lateral sides of the casing, illustrating the construction of the pivot blocks for the cradle orcrank shaft.

Fig. 5 is a sectional view taken on a ver tical plane extending centrally and longitudinally through the ash sifter, illustrating the manner in which the sifter may be supported through the medium of the handie and the rear end of the casing when it is desired to assemble the sifter and cradle or dcrank shaft, the cover being removed, an

F ig. 6 is a similar view illustrating the mannerin which the siftermaybe tilted upwardly upon the rear end of the casing when it is desired to discharge the ashes from the sifter. 1

Referring to the drawings by reference numerals, 1 designates the bottom wall. 2 the side walls, 3 the front end wall and 4 the rear end wall of the casing of my improved ash sifter. The upper side of the casing is fully open. A cover comprising a top wall 5, side walls 6, a front end wall 7 and a rear end wall 8, is removably mounted upon the casing to close the upper open side thereof. The transverse and longitudinal dimensions of the cover are equal; to the similar dimensions of the casing so that when the cover is in applied position, the lower edges vof its side walls 6 and front and rear walls 7 and 8 rest upon the upper edges of the side walls 2 and front and rear walls 3 and 4c of the casing. To hold the cover against transverse and longitudinal displacement, and to prevent the escape of dust from the casing during thesifting operation,-the cover isprovidedwith depending side cleats or flanges 9, a front endcleat or flange 10 and arear end cle'at or flange 11. These cleats or flanges embrace the side across the joints between the side and end walls of the casing and the side and end walls of the cover. To permit the cover to be easily applied and removed, it is provided with a handle 12.

A cradle or crank shaft which consists of vertical members 13, a horizontal member 1 1 and pivots or journals 15, is pivotally mounted within the casing through the medium of the journals 15 which rest in the open bearings 16 of blocks 17. The bearing blocks 17 are secured to the upper edges of the side walls 2 of the casing and the side walls 6 of the cover are recessed as at 18 to receive the bearing blocks. One of the pivots or hearing journals 15 is provided with a downwardly and forwardly extending crank arm 19 provided at its lower end with a handle 20. The crank arm 19 and handle 20 provide means by which the cradle or crank shaft may be swung into the position in which it is illustrated in Fig. 5 of the drawings when it is desired to assemble the sifter and cradle or crank shaft. As the bearings 16 are open, the cradle may be readily and quickly applied to and removed from the casing.

A sifter which is pivotally and removably mounted upon the horizontal member 14 of the cradle or crank shaft, comprises side walls 21, a front end wall 22 and a rear end wall 23. The sifter also comprises a reticulated bottom wall 24. A pair of blocks 25 is secured to the lower edges of the side walls 21 at a point in rear of the vertical center thereof, and these blocks are provided with open bearings 26 which receive the horizontal member 14 of the cradle or crank shaft. A handle 27, which extends through an opening 28 in the front wall 7 of the cover, is pivoted to the front wall 22 of the sifter near the upper edge thereof by means of a hinge 29. The handle 27 provides means by which a forward and upward and rearward and upward motion may be imparted to the sifter, these movements of the sifter resulting in the effective sifting of the ashes in a comparatively short time. The pintle 30 of the hinge 29 is removable to permit the handle 27 to be detached from the sifter when it is desired to store or ship the ash sifter.

To permit the sifter to be supported through the medium of the rear end wall A of the casing and the handle 27, when it is desired to discharge the cinders from the sifter, or when it is desired to assemble the cradle 01' crank shaft and sifter, a pivot or fulcrum block 31 is secured to the rear end wall 23 adjacent the upper edge thereof. When it is desired to discharge the cinders from the sifter, the cover is first removed,

and then a rearward and upward movement is imparted tothe rear end of the sifter through the medium of the handle 27. By

imparting this movement to the rear end of the sifter, the pivot or fulcrum block 31 is positioned upon the upper edge of the rear end wall A of the casing. The sifter is then tilted in an upwardly and rearwardly inclined direction through the medium of the handle 27 to discharge the cinders therefrom into a receptacle, not shown, located at the rear end of the casing. When it is desired to remove the fine ashes from the casing, the cover, the cradle or crank shaft and the sifter are first removed. To reassemble the parts, the cradle or crank shaft is first placed in the casing with its journals 15 in the bearings 16. The sifter is then placed within the casing with its pivot or fulcrum block 31 resting upon the upper edge of the rear end wall 1 of the casing to support the rear end of the sifter, the front end of the sifter being supported by the handle 27, after which the cradle 01' crank shaft is swungin a rearward and upward direction through the medium of the crank 19 and handle 20 to position the horizontal member 14: in the bearings 26. The handle 27 is then pulled forwardly to remove the pivot or fulcrum block 31 from the upper edge of the rear end wall 4 of the casing, and to permit the sifter to be wholly supported by the cradle or crank shaft. After the ashes have been placed in the sifter, the cover is applied. In order toenable the operator to determine when the horizontal memoer 14 is located in the bearings 26 during (the assembling of the sifter and the cradle or crank shaft in the manner hereinbefore pointed out, a stop 32 for engagement by the arm 19 is secured to one side Wall 2 of the casing. The stop 32 is so positioned that it will be engaged by the arm 19 when the cradle or crank shaft has been swung far enough in a rearward and upward direction to position the horizontal member 14 in 1116 hearing 26 during the assembling of the sifter and cradle or crank shaft.

From the foregoing description taken in connection with the accompanying drawings, it should be apparent that I provide an ash sifter which is simple, durable and efficient, and which may be manufactured and sold at a comparatively low cost. It should also be apparent that it requires the expenditure of but a comparatively small amount of energy to effectively operate the ash sifter.

To permit the ash sifter to be moved from place to place, hand grips 33 are secured to the end walls 3 and 4: ofthe casing.

While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in the construction, combination and arrangement of parts may be made without depart ing from the spirit and scope of the invention as defined by the claims.

Having thus fully described myinveni wardly by the handle through the open side of the easing into dumping position and to permit the sitter to be supported by the casing and handle during the placing ot the cradle in the bearings, a crank handle connected to the cradle, and a member carried by the casing for engagement by said crank handle when the cradle is positioned in the bearings while the sitter is supported by the casing and handle.

2. An ash sitter comprising a casing, a single cradle pivotally and removably mounted within the casing, a sitter pr vided on its under side intermediate the ends thereof with open bearings to receive the cradle, a handle pivoted to one end of the sitter, a pivot block carried by the sitter and adapted to be positioned upon the under edge ot the casing to permit the sitter to be swung upwardly by the handle into dumping position and to permit the sitter to be supported by the casing and handle during the placing of the cradle in the bearings, a crank handle connected to the cradle, and a member carried by the casing tor engagement by the crank handle when the cradle is positioned in the bearings while the sitter is supported by the casing and handle.

In testimony whereof I atfix my signature in presence of two witnesses.

WILLIAM C. ANDERSON.
