ASH-SIFTER FOR FURNACES AND THE LIKE.

Application filed November 12,1917.

to which it appertains to make and use the same.

My invention has for its object to provide an extremely simple and highly eflicient ash sifter for furnaces andthe like; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings,

Figure 1 is a fragmentary perspective view of the base section and grate bars of a hot water boiler having the invention applied thereto;

Fig. 2 is a perspective view of one of the sections of the ash sifter;

Fig. 3 is a perspective view of the support for the ash sifter;

Fig. *1 is a fragmentary perspective view of the support, with the longitudinal tie bar separated from the transverse tie bar to illustrate the interlocking notches; and

Fig. 5 is a detail view with some parts sectioned on the line 55 of Fig. 4, on an enlarged scale. I

The numeral 6 indicates the cast annular metal base section of a hot water boiler, of the type for heating houses, schools and the like. This base section 6 affords an ash pit 7 and has a contracted front extension 8, in which is formed a door opening 9 normally closed by a hinged door 10. Mounted on the base section 6, are grate bars 11 connected by a horizontal shaking bar 12, the outer end portion of which works through an aperture in the base extension 8, at one side of the door 10. The customary shaking lever, not shown, will be provided for oscillating the connecting bar 12. The parts thus far described are of standard construction and have been illustrated simply for the purpose of showing the invention applied in working posltion.

Referring now in detail to the invention,

Specification of Letters Patent.

Serial No. 201,655.

the numeral 13 indicates the improved sifter, which comprises two duplicate sections, the outer edges of which closely follow the contour of the base section 6 and extensions 8, so that all ashes, cinders and coal dropping between the grate bars 11 will be precipitated thereon. The sections of the sifter 13 are, as shown, preferably made from woven wire, having a mesh that will permit the ashes to fall therethrough, but will hold the cinders and coal. To prevent the cinders and coal from rolling off from the outer edges of the sections of the sifter 13, the same are provided with upturned marginal flanges 14, except at their front edges, which are left open, so that the cinders and coal may be raked on from the sifter into a shovel, bucket or other receptacle placed in the door opening 9 under the front end of said sifter. i

The flanges 14, in addition to holding the cinders and coal on the sifter, reinforce the same and are preferably made from imperforate material, but may be formed by bending up the outer marginal edges of the sections of the sifter and folding said edges around a heavy reinforcing wire. Preferably, but not necessarily, the inner longitudinal edge portions of the sections of the sifter 13 are overlapped, as shown in Fig. 1. Each section of the sifter 13 is of such size as to permit the same to be inserted through the door opening 9 or re moved therefrom.

To removably support the ash sifter in the ash pit 7, under the grate bars 11, I provide two pairs of standards 15, transverse tie bars 16 and longitudinal tie bars 17. The standards 15 have feet extensions 18, adapting the same to stand alone on the floor of the ash pit 7. The upper ends of the standards 15 are bifurcated to receive and support the transverse tie bars 16 on edge and the one in front of the other, as best shown in Fig. 3. Nut-equipped bolts 19, passed through alined bores in the prongs of the bifurcated ends of the standards 15 and in the transverse tie bars 16, detachably connect the said tie bars and standards.

The longitudinal tie bars 17 are supported on the transverse tie bars 16 and hold the same properly spaced, with respect to each other. Co'ciperating inner notches 20 are formed in the upper edges of the tie bars 16 and in the lower edges of the tie bars 17 to hold the same in their proper relation, with respect to each other. These interlocking notches 20 permit the longitudinal tie bars 1? to be readily detached from the ransverse tie bars 16, so that said transverse tie bars and connected pairs of standards 15 may be independently removed from the ash pit 7 through the door opening 9, after the sections of the sitter 13 have been removed therefrom.

From the above description it is evident that the ash sitter and its support may be very quickly set up in position in the ash pit 7 under the grate bars 11, or removed therefrom. it is also evident that the standards 15 are so spaced, that most of the ashes in the ash pit 7 may he removed from under the siit'ter 13, Without disturbing the same. From actual usage of the invention, it has been found only nece ary to remove the ash sitter and its support from the ash pit about once a vveelt, in order to remove all oi the ashes from the ash pit and the Cinders and coal deposited on the ash sitter.

ll hen the cinders and coal are scraped from the sitter into a shovel or receptacle of patent be obtained for fr said cinders may he removed and the partly burnt or good coal thrown back onto the fire or into the coal bin. Of course, the cinders and coal may he raked from the ash sitter directly onto the floor, in front of the door opening 9, and then shoveled onto the fire or into the coal bin. The tie bars 16 and 1? firmly support the sections of the ash sitter l3 thereon and prevent the same from tipping, nnderthe Weight of the ashes, cinders or coal precipitated thereon when shaking the grate bars 11.

lVhat Z claim is:

A sitter having a laterally enlarged body and a narrow neck, and a flange surrounding the sitter except the free end of the neck, said sitter being" longitudinally divided through the neck and the body of the sitter to provide correlated sections.

In testimony whereof l affix my signature in presence of two Witnesses.
