Patented Oct. 27, 1931- UNITED STATES PATENT OFFICE HERBERT HENRY BAKER, OF MONKSEATON, NORTHUMBEBLAND, AND CHRISTOPHER SAMUEL DAVY, OF DULWICH, LONDON, ENGLAND, ASSIGNORS'TO THE BAIBOOQK &
WILOOX COMPANY, OF BAYONNE, NEW JERSEY,
A CORPORATIQN OF NEW JERSEY DISTRIBUTING MEANS r03. rUEL 'ro s'roxnas- Application filed October 80, 1919, Serial No. 334,508, and in Great Britain November 27, 1918.
The invention relates to improved means for uniformly distributing the fuel on to the grate surface of a mechanical stoker and has for its object to ensure that the dust and larger pieces of fuel as delivered from the bunker shall be thoroughly mixed and equally distributed across the grate surface of the stoker,
Theinvention consists broadly in the provision of means whereby the lower end of'a chute leading to the stoker is caused to travel back and forth transversely of the direction in which thefuel is fed by the stoker.
In the accompanying drawings, Fig. 1 is a side elevation partially in section, and 'Fig. 2 an end elevation of an arrangement according to the invention;
In the embodiment of the invention illustrated, there is mounted above the stoker hopper 1 a rotary cylinder or drum 2 formed with a'cam track constituted by two helical grooves 3 of opposite hand adapted to be entered by a follower constituted, for' example, by a snug on a nut-forming element4 which is attached to the lower end of the hanging chute 5 supplying fuel from the bunker 6 to the hopper 1, and which in the rotation of the cylinder or drum 2 is caused to reciprocate axially thereof. l
v The cylinder or drum 2 may be driven by chain-gearing or otherwise from'a revolving shaft, such as the sprocket shaft at the front of the stoker, if of the chain grate type, or
ment being continuous,
from a separate shaft. In the embodiment shown, the cylinder or drum 2 is driven from the shaft 7 of the stoker mechanism A; I
It will beevident that as the cylinder or drum 2 rotates, the lower end of the chute 5 will travel across the stoker hopper 1, and upon reaching the end of its travel in one direction, will travel the same distance in the opposite direction,
so that the dust and larger pieces of fuel discharged from the chute will be well distributed in the stoker hopper.
What we claim and desire to secure by Letters Patent of the United States is 1. In combination, a-mechanical stoker havinga grate, a hopper extending crosswise of the grate, a chute for conveying fuel to the.
hopper, and operating means connected to the chute and constructed and arranged to structed and arranged to move the lower end of the chute back and forth lengthwise of said hopper, whereby a substantially; uniform distribution of the fuel in said opper is effected.
3. In combination, a mechanical stoker and means for operating the same, a chute for conveying fuel to the stoker, an operatin shaft, driving connections between saidsha and the stoker, and means associated withsaid shaft to move the lower end of said chute back and forth transversely of the direction in which the fuel is fed by said stoker.
4. In combination with an automatic stoka swinging coal-feeding er having a hopper into and distributing chute for feeding coal it along said hopper, a member movable alon said hopper, said member being connecte to said chute, a rotatable shaft, driving means for rotating said shaft constantly in one direction, and periodically reversible powertransmission mechanism operatively interconnecting-said shaft and said member to.
cause reciprocation of said member and chute along the hopper;
