ASH-EXETER.

Specification of Letters Patent.

Patented Aug. 1'7, 1909.

Application led September 1S, 1908. Serial No. @31358.

To all w71 om it may concern:

Be it known that l, J o1-i1\v FAnNwon'ri-r, a subject of the King of Great Britain, residing in the town o1c Hespeler, county of l/lfvaterloo, Province of Ontario, Canada, have invented certain new and useiiul improvements in Ash-Sitters, ot' which the following is a speciication.

My invention relates to improvements in ash-sitters more particularly of that class in which the ash-pan is inverted so as to precipitate the ashes therefrom onto an inclined screen, and the principal object of my invention is to provide means tor holding the ashpan on a tilting-frame so that it will not fall therefrom when the sitter is in use.

The construction and operation of my ashsinter will be hereinafter particularly described, and the parts T claim as new will be pointed out in the accompanying claims.

Figure l is a perspective view of my asl sitter with the upper door open showing the tilting-frame in its normal position, and Fig. 2 is a vertical central section through the ash-sitter.

In the drawings, like characters ol' reference indicate corresponding parts in each ligure.

The frame of the ash-sitter may be of any suitable construction, and same is shown provided with a door A which is designed to close the opening B. Substantially on a level with the bottom of the opening B, is the tilting-trame which may be of any suitable construction. According to the construction shown the same consists of iront and rear cross-pieces C and D which support in relative position the longitudinal members E, the inner ends of which are curved upward as shown at F s0 that the inner end of the ash-pan G will rest thereagainst, and against the cross-piece D when in the dotted position shown in Fig. 2.

H is a bar secured to the frame at the opening B and upon which rests the crosspiece C.

Journaled in the sides of the frame of the ash-sitter is the tilting-bar which is suitably 'the back of the iframe ol the ash-sitter. .it

will be noticed that the ash-pan G rests upon the tilting-traine underneath the retainerbar 8 so therefore when the ash-pan is tilted to occupy the position shown in dotted lines, it will abut against tue retainer-bar 3 and swing it and the side-pieces e into the dotted position shown, thus putting the springs 5 under tension.

6 is a chute supported at a downward-inclined angle within the frame of the ashsifter and in such position as to forni a stop for the inner end of the tilting-trame, as will be clearly seen upon reference to Fig. 2.

When the ashes have been dumped out ol the ash-pan, the operator will oll course move the tilting-frame and ash-pan carried thereby, bach to normal position.

Tn order to prevent the mixed cinders and ashes from passing too rapidly down over the screen 2, l loosely mount the swinging apron 7 on the rod 8 (which rod is supported in the sides ol' the ash-siiter-frame) below the lower edge ol' the chute 6. In its normal position, the swinging-apron 7 rests against the screen 2. BecauseV ol' the weight of the mixed ashes and cinders, the swinging-apron 7 is moved on its rod 8 and thus allows a downward passage of the mined cinders and ashes in such volume as to insure the thorough separation of the ashes from the cinders before the cinders fall into the cinderdrawer 9 held in the bottom of the ash-sitterframe.

l0 are a plurality ol' inwardly projecting aprons designed to extend over the ashdrawer 1l held in the bottom ol the ashsi'l'ter-franie. These aprons are situated so as to insure the passage of the ashes into the said ash-drawer.

It will be noticed that the screen 2 at its lower portion is provided with sides l2 which are designed to converge so as to delect the cinders into the cinder-drawer 9.

ln order to provide suliicient room l'or the accommodation of the drawers 9 and 1l, the ash-sifter-lrame is prelerably provided with a lront extension 13. The drawers 9 and l1 are provided with any suitable grips 14 and 15 respectively.

It Will of course be understood that all joints and other places Where dust is likely to escape from the ash-sifter-frame may be faced with felt O or other suitable material so as to prevent the escape of dust from the ash-sifter.

What I claim as my invention is l. In an ash-sifter, the combination with the frame thereof provided with a screen, and a tilting frame mounted in said ashsifter frame above said screen of spring-controlled means mounted in said ash-sifter frame above said tilting frame and designed to be engaged by an ash-pan carried by said tilting frame when the same is moved a certain distance so as to prevent the ash-panV from falling away therefrom7 and means carried by said tilting frame so as to prevent the ash-pan siiding therefrom.

2. In an ash-sifter, the combination with the frame thereof provided with an inclined screen; a tilting bar mounted in said ashsifter frame7 and a tiiting frame mounted on said tilting bar above said screen, of a spring-controlled retainer-bar mounted on said tilting bar and extending above said tilting frame and designed to be engaged by an ashpan carried by said tilting frame When the latter is moved a certain distance so as to prevent the ash-pan from falling away therefrom, and means carried by said tilting frame so as to prevent the ash-pan sliding therefrom.

3. In an ash-sifter, the combination With the frame thereof provided with an inclined screen a tilting bar mounted in said ashsifter frame, and a tilting frame mounted on said tilting bar above said screen; of side pieces mounted on said tilting bar so as to extend above and below the said tilting frame; a retainer bar mounted in the upper ends of said side pieces so as to be above said tilting frame and designed to be engaged by an ash-pan carried by the tilting frame when the latter is moved a certain distance so as to prevent the ash-pan from falling away therefrom; springs connecting the lower ends of said side pieces with vthe said frame and whereby the said retainer bar is held against the ash-pan When the same is in the position to dump, and means carried by said tilting frame to prevent the ash-pan from sliding therefrom.

In testimony whereof l have signed my name to this specification, in the presence of tivo subscribing Witnesses.

JOHN FARNWQRTH.
