DUSTLESS ASH-SIFTER.
Specification of Letters Patent.
Patented Nov. 10, 1914..
Application filed November 26;;1913. Serial No. 803,288.
To all whom it may concern: Be it known that I, WILHELM TEG, a c1t1- zen of theUnited States, residing at Lake Park, in the county of Becker and State of Minnesota, have invented new and useful improvements in Dustless Ash-Sifters, of
which the following is a specification.
This invention is an improved ashsifter, the object of the invention being to provide an improved sifter which is dustless, which is easily operated, which is not likely to get out of order, which can be cheaply manufactured and which is exceedingly strong and durable.
The invention consists in the construction,
combination and arrangement of devices hereinafter described and claimed.
In the accompanying drawings :-Figure 1 is partly an elevation and'partly a sectional view of an ash sifter constructed in accordance with my invention. Fig. 2 is a sectional view of the same on the plane indicated by the line a-a of Fig. 1. Fig. 3 is a detail elevation of a portion of the .peripheral side of the revoluble screen. Fig.
4; is a detail sectional view of the same on the plane indicated by the line bb of Fig. 3. Fig. 5 is a similar view on the plane indicated by the line oc of Fig. 3. Fig. 6 is a detail View, partly in elevation and partly in section and showing the construction of the crank shaft of the revoluble screen element, the bearings therefor and parts of the screen and of the casing.
The ash receiving can 1 is here shown ascylindrical and is provided on opposite sides with fixed handles 2. The cover 3 of the said can is removable therefrom and is provided with handles 4:. At the center of the cover is an opening 5 around the sides of which is an upturned flange 6. A revoluble screen 7 is also provided which is cylin drical in form, with a horizontal axis and is mounted for revolution in a casing 8 which is nearly cylindrical in form.
The casing comprises oppositely arranged side walls 9-10 and its peripheral wall 11. The wall 10 is removable. At the lower side of the casing is an opening 12 to coincide with the opening 5 in the can cover 3 and a flange 13 extends downwardly from the walls of the casing and around said opening 12, the said flange 13 being adapted to be fitted within the flange 6 of the can cover to detachably secure the casing on the'top of the can. Atthe top of the casing Sis-an opening 14 around which is a frame 15. A I
, The revoluble screen 7 comprises vertical circular walls 18 which are connected to+v gether by transversely arranged braces '19 that are appropriately spaced apart. These braces are made of suitable .sheet metal and are provided at their'ends with inturned portions 20 to bear against the inner sides of the walls 18 and to be s'ecured to said walls as by means of rivets or other suitable fastening devices and each brace is provided near each end with an.out-
turned lip 21 which is struck up therefrom and is integral therewith. The peripheral or cylindrical wall 22 of the'screen is made of wire mesh. material of suitable gage of wire and suitable size of mesh and at the sides and. across the ends of the saidscreen 22 is a reinforcing wire 23. An opening 24 is formed between the ends of the screen 22. The screen is arranged between the walls 18 with its reinforcing wires 23 hearing against said walls, the screen being stretched over and supported by the braces 19 and its reinforcing wires 23 being engaged and held by the lips 21 of the braces as shown. Hence the screen is rendered exceedingly strong, is sustained at all points against sagging and may be readily removed and replaced by a new one at small cost when worn out. The cover 24: for the opening in the screen is also made of suitable wire mesh material andis reinforced at its sides and ends by a wire frame 25 which. is provided at its corners with outwardly extending offset portions 26. These offset portions engage the channels on the inner sides of a pair of curved channel bars 27 which are secured on the inner sides of the walls 18, at their peripheries, the said channel bars extending on opposite sides of and past the opening in the screen. Hence the said channel bars form supporting guides for the cover 24 and adapt the latter to be moved in either direction, to cover or uncover the opening in the screen. The ends of the channel bars forcing frame of the cover 24: when the latter is in either of its two positions, and thus secure the cover in either position against casual movement by the camming action of said bent ends of the channel bars.
The axle shaft 28 of the revoluble screen is provided with squared portions 29 near its ends which pass through similarly shaped openings in the walls 18 of the screen, the said walls being formed with struck up portions 23 around said openings which bear on and are secured to the squared portions of the axle shaft. One end 29 of the axle shaft is mounted for rotation in a cylindrical bearing 80 which has an outturned base 31 riveted to the inner side of the wall 9 of the casing 8, at the center of the said wall. Hence the axle shaft may be readily unshipped from this bearing. The other end of the aXle shaft has a bearing in an opening in the wall 10 of the casing, Which wall is removable as hereinbefore stated and is provided with a cylindrical bearing 31 similar to the bearing 31. These bearings engage opposite sides of the screen and hold the latter against endWise movement. 32 is detachably secured on the axle shaft at a point without the Wall 10 and the outer end of the axle shaft is squared and engaged by a detachable crank handle 33 which enables the screen 7 to be readily rotated in the casing. In order to remove the screen from the casing the crank handle should be first detached from the axle shaft 28 and A washer the wall 10 should be then removed from the casing.
The operation of my improved ash sifter is as followsz-By first removing the cover 16 of the casing and then opening the cover 24: of the screen, the cinders to be sifted can be placed in said screen. Said covers are then closed and the screen rotated. The screen mesh material 22 retains the cinders in the screen but permits the passage of the ashes and small particles therethrough. The ashes drop into the can 1. When the material has been sufliciently sifted the casing can be removed from the cover 3 and the cover 24: of the screen then opened, thus permitting the sifted cinders to be discharged through the opening in the screen.
Having thus described my invention, I claim:
In an ash sifter, a revoluble screen comprising side walls, braces connecting said side walls and having outwardly projecting lips, and a screen element of mesh material arranged on the outer sides of said braces and between said walls of the screen and having reinforcing wires at the sides bearing on the said braces and engaged and held in place by the lips thereof.
In testimony whereof I afliX my signature in presence of two witnesses.
WILHELM TEG.
