To all whom it may concern:

Be it known that We, NATHAN S. BEEBE, re siding at Springfield, and ABRAEIAM A. BOUR- GEOIS, residing at East Long Meadow, in the county of Hampden and State of Massachusette, citizens of the United States of America, have invented new and useful Improvements in Mechanical Stokers for Boiler or other Furnaees, of which the followingis a specification. This invention relates to mechanical stokers for boiler or other furnaces, and has for its object the construction of such a stoking device whereby an even distribution of fuel is assured throughout the length of the fire-box of said furnace; and it eonsist'in the construction and arrangement of the devices for the above-mentioned purpose, all as hereinafter fully described and vciaimed.

In the drawings forming part of this speciiication, Figure l is a plan view in section of 4a part of a boiler or other fire-box and th@ stoking mechanism therefor. Fig. 2 is a side elevation of the same, also in section. Referring to the drawings, Aisthe fire-box, and B is the daring mouthpiece of the trough C. Said trough is of rectangularforni in crosssection and is carried back away from said fire-box to the source of supply of the fuel to be used in the fire-box. The mouthpiece B thereof is preferably madeof cast.-`iron,- as it is subjected to quite a high temperature,whieh would cause the distortion thereof if it were made of sheet metal, which is the material used in the construction of said trough C.

In mechanical stokers as ordinarily made it is im possible to get a uniform distribution of the fuel, especially where they are applied to the furnaces of boilers used 'in the woodworking industries,where the said fuel being of a very light nature a strongaincurrent is employed.v to convey`it to the furnace from various parts of the mill. Under such conditions the fuei is piled up alongA the side of the fire-box opposite the mouth of the delivery-pipe, andis not only very wasteful of fuel, but requires the attention of a fireman to even it up over the surface of the grate-bars. To obviate these cbjections,we have constructed the mouth of the fuel-distributing pipe very flaring horizontally and located therein a swinging vertical partition D, secured to a vertical shaft E, located substan tially midway7 between the ends of said partition. On o'nc end of said vertical shaft is secured a crankarm F, connected by a pitman G or connecting-rod to a smaller crank rotated by a pulley7 II or other suitable meanswhereby more y or less rapidI oscillatory motion may be im' parted to lthe said swing partition. The said partition is of cast-iron or other suitable metal, and the inner 'end L thereof is made thin to easily part the stream of fuel directed against it by the air-current. From said end L to the opposite end thereof it is tapered to form the wedgeshaped partition shown in the drawings. When near tlie' end next to the {ire-box, the sides of said partition are curved quite sharply outward, as at M,to the end that the stream of fuel carried by the air-current may be deliected toward the ends of the refbox as the said partition swings from side to side. way between the vertical sides of the mouthpiece B of the Stoker, the divided stream takes a nearly straight course,being very little eifected by the curved sides of said partition, and thus the part of the fire-box in a line with said, partition D is supplied with fuel Secuged'to the inside of the small end of the said mouthpiece are two springs O O, against which the end of the .partition strikes as it is oscillated by its driving mechanism.

Having thus described our invention,what we claim, and desire to secure by Letters Pat-v ent, is

1. In a mechanical Stoker, the swinging divisional partition centrally located within the enlarged end of a fuel-delivering conduit, said partition being tapered from one end to the other, and the sides thereof at its larger end being outwardly tapering, and means for imparting a reeiprocatory motion to said partition, substantially as described.

2. In a mechanical Stoker, the swinging divisional partition centrally located within the enlarged end of a fuel-delveringconduit, said W'hen said partition is about mid' partition being tapered from one end to the other, and the sides thereof at its larger end being outwardly tapering, and buier-springs to receivethe impact of the end of said swinging partition, and means for imparting mo- .tion to said swinging partition, substantially IOO
