I To all whom it may concern:

Be it known that I, HOWARD I. GEN'rINn,

a citizen of the United States, and a resident of Shelbyville, in the county of Shelby and State of Illinois, have invented a new and useful Pulverized-Fuel Feeder and Mixer, of which the following is a specifiis to provide a mechanism w cation.

My invention relates to pulverized fuel feeders and mixers and its primary object erein the pulverized fuel will be continuously fed to a mixing chamber where it is mixed wlth air and nce discharged into the firebox of a furnace.

A further, object of the invention is to provide a fuel feeder whereln fuel 1s kept in motion by a rotating turn table and thus caused, by centrifugal action, to be fedto the furnace firebox.

It is also an object of theinvention to provide means wherein the fuel supply and air supply may be regulated ,th'roughthe medium ofa common operating mechamsm.

in the novel combination of elements, construction and arrangement of parts and operations to be hereinafter fully described, claimed and illustrated in the accompany in drawings, wherein:

Figure 4 1s a fragmentary elevation illustrating'the manner in which the fuel hopper is supported.

motor 11. Rotatabl sup, orted on' the gear box 12 1s a vertica shaf t 14 to the upper end of which a turn table or disk 15 is fixed. Secured to the shaft 14 below the disk 15 is a relatively large gear 16. A vertically dlsposed power shaft 17 has operative connection with the gears ,in the gear box 12' and carries, at itsupper end, a drive p1n1o n 18 meshing with the gear 16 to impart rotat on thereto. Suspended in the floor or ce1l1ng 19 is a hopper 20 in which the pulverized fuel is placed, and secured to the mouth of the hopper and overlying the Patented $1 1 118 13, 1922..

turn table 15 is a rectangular bottomless casing 21.

Mounted in guides 22 at the forward end of the casing is a vertically movable gate or sllde valve 23 adapted to be adjusted to regulate the quantity of pulverized fuel to be fed from the rotating disk or turn table.

Communicating with the airinlet pipe 7 is a vertically arranged dischargechute 24which is disposed forwardly. of the hopper 21 and is formed with a longitudinal slot25 in which the disk or turn table'15 pro- ]ects. A regulating slide valve 26 is mounted 1n the upper end of this chute and controls the fuel from the disk to the moving off the turn table after the same is fed out beyond the casin 21, there is provlded a forwardly exten mg wall'27 which is mounted upon the forward wall of the casing 21'. 1

A butter-fly valve 28 is pivoted in the pipe 7 to control the air passing to the casing 6, and pivotally connected with an arm 29 fixed to the axis of the valve 28 is a link 30 pivoted intermediate its ends, as-shown In order to prevent the fuel from a at 31. An operating .lever 32 has one end pivoted to the casing 21 and to this operatlng lever 32 the upper end of the link 30 is pivotally connected. A link 33 has one end pivotally connected with the slide or gate valve 23 and its opposite end pivotally connected with the operating lever 32.

a It will thus be seen, that upon manipulating the lever '32, both the butter-fly valve and the gate valve may be adjusted to permit the fuel and air to be fed to the casing 6 in the proper proportions. In order to prevent the fuel from massing in the hopper 20, a pair of vertically arranged agitator blades 34 is fixed to the upper end a discharge chute arranged forwardly of the v of the shaft 14, which blades project into the hopper 20.

In the operation it will be obv1ous'that as the fuel gravitates from the hopper 20 it is fed outwardly upon the disk 15 by centrifugal force and as the fuel banks orpiles at the wall 27, it is gradually thrown through the slot 25 and carried to the pipe 7 by way of the discharge chute 24. The.

amount of fuel to be permitted to pass from the disk 15 to the chute 24 is governed by the valve 26.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, what I claim as new and desire'to secure and protect by Letters Patent of the United States, is.:':

-1. A mechanism of the character described comprising a fan casing having an inlet and an outlet, a, hopper supported at one side of the fan casing adapted to contain fuel to be fed to the latter, a vertically movable valve for controlling the amount of fuel to be fed from the casing, a rotatable turn table'mounted below the hopper, a discharge chute arranged forwardly of the turntable and communicatin with the 'fan inlet," and a forwardly exten in wall projecting from the hopper and overlylngthe turn table and adapted to prevent the fuel from moving with the'latter. y x

2. A mechanism of the character described comprising a fan casing having an inlet and an outlet, a hopper supported at one side of the fan casing adapted to contain fuel to be fed to the latter, a vertically movable valve for controlling the amount of fuel to be fed from the casing, a rotatable turn table mounted below the hopper,

turn table land communicating with the fan inlet, a forwardly extending wall projecting from the hopper and overlying the turn table and adapted to prevent the fuel from moving with. the latter, and earing operatively connecting the motor wlth the turn table.

3. A mechanism of the character described comprising a fan casing having an inlet and an outlet, a hopper supported at one side of the fan casing adapted to contain fuel to be fed to the latter, a vertically movable valve for controlling the amount of fuel to be fed from thetcasing, a vertically arranged rotatable shaft, a turn table fixed to the upper end thereof and disposed below I the hopper, a discharge chute arranged forwardly of the turn table and communicating with the fan inlet, a forwardly extending wall projecting from the hopper and overlyin the turn table and adapted to prevent 51c fuel from moving with the latter, a relatively large gear fixed to the shaft, a drive pinion meshing with the gear, and a motor operatively connected I with the ,drive pinion. 1

4. A mechanism of the character described comprising a fan casing having an inlet and an outlet, a hopper supported ,at one side of the fan casing and adapted to contain fuel to be fed to the latter, a' vertically movable valve for controlling the passage of fuel to the casing, a rotatable table disposed below the hopper, a discharge chute ling valve.
