Specification of Letters Patent.

Patented Jan. 9, 1906.

Application Eea July 1o, 1903. serial No. 164.934.

To all, whom t may concern:

Be it known that I, JEROME R. GEORGE, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Gas-Producers, of which the following is a specification, accompanied by a drawing forming a part of the same.

The figure represents a vertical central sectional view of the upper half of a gas-producer, showing the feeding mechanism for supplying fuel to the gas-producing chamber.

' denotes the chamber of a gas-producer, in-

closed in the present instance by circular walls 2 and having a top plate or cover 3 provided with a central opening 4 for the admission of fuel. Standing upon the top plate are legs, one of which is shown at 5, and supported on the legs 5 at some distance above the top plate is a stationary coal-reservoir 6, provided at its upper end with an opening 7 for the reception of coal, normally closed by a damper 8. The coalreservoir is contracted in diameter near the bottom, forming a hopper-shaped section 9, with a restricted passage 10 for the deliver of coal to a rotating coal-distributer 11, p aced upon the coal-reservoir and the top plate of the gasproducer. The upper edge`12 of the coal-distributer is cylindrical and inclosesthe lower cylindrical edge 13 of the coal-reservoir. The lower portion of the coal-distributer is gradually contracted in diameter and is provided at its lower end with a delivery-openin 14,

inclosed within the central opening 4 o the top plate. The upper circular end of the coal-distributer is concentric withthe open-' ing 4 in the top plate of the gas-producer; but the delivery opening 14 is eccentric thereto, so that upon one side' of the distributer its wall is substantially vertical, as at 15, with an inclined wall 16 upon its diametrically opposite side with the intervening walls of varying inclinations, so that coal passing from the reservoir 6 through the distributer adjacent to the vertical wall 15 will fall into the gas-producing chamber at a slight inclination from a vertical line, as represented by the broken line 17, and be deposited near the center of the chamber, while coal falling upon the opposite inclined side 16 will slide therefrom and be carried in a slightly-curved line, as shown by the broken line 18, nearer the outside of the gas-producing chamber.

The coal-distributer is connected by radial arms 19 with a central hub 20, which is attached to the lower end of a vertical rotating spindle 21, journaled in a fixed hub 22, which is connected by the radial arms 28 with the coal-reservoir 6. The upper end of the spindle 21 is screw-threaded and provided with a nut 24, by which the spindle 21 and suspended coal-distributer may be vertically adjusted in its supporting-hub 22. The rotating hub 20, to which the coal-distributer is attached, extends upward into the restricted coal-passage 10 in the coal-reservoir, and it is provided with radial projecting ribs 25, adapted to agitate the coal as it passes through the gassage 10. The downward flow of coal through the passage 1() from the reservoir 6 into the distributer 11 is impeded by a disk 26, the diameter of which is greater than the diameter of the coal-passage 10, so that when the coal-distributer is at rest coal passing through the passage 10 will be caught by and held by the disk 26, the diameter of the disk and the distance between it and the restricted passage 10 of the coal-reservoir being such that the coal will be held upon the disk within the angle ofrepose. The agita-- tion or disturbance of the coal resting upon the disk 26 such as that caused by the rotation of the coal-distributer 11, will cause the coal to move over the edge of the disk and fall into the coal-distributer and be deliv? ered through the opening 14 and distributed between the center and outside of the heating-chamber, the rotation of the distributer 11 placing the coal in a uniform layer within the heating chamber. To facilitate the movement of the coal off the disk 26, its upper surface 27 is preferably slightly inclined, and the delivery of coal over the outer edge of the disk 26 can also be varied by the ver- IOC tical adjustment of the coal-distributer relatively to the coal-reservoir by means of the nut 24 on the screw-threaded end of the rotating spindle 21, thereby increasing or decreasing the vertical space between the contracted coal-passage 10 and the upper surface of the disk 26.

The upper and lower edges of the coal-distributer l 1 are water-sealed in the usual manner of water-sealing the oints in the feeding devices of gas-producers. The rotating coaldistributer l1 is provided with teeth 28, by which the distributer is rotated by means of any suitable actuating mechanism, consisting in the present instance of a rocking shaft 29 and a pawl 30,' but the method of rotating the distributer forms no part of my present invention, and therefore is not herein described in detail.

In the operation of feeding coal to the heating-chamber by my improved feeding mechanisin coal is freely carried by gravity through the passage 10 of the coal-reservoir owing to the inclined or hopper-shaped sides 9 of the distributer until it strikes upon the upper surface 27 of the disk 26, which impedes the direct downward flow of coal by gravity, causing it to bedellected from the center outwardly over the edge of the disk 26, from which it is carried b y gravity vertically downward, a portion passing through the opening 14 of the coal-distributer and the remaining portion impinging against the inclined sides of the coal-distributer by which the direction of the coal is changed, as already described, thereby causing the coal delivered through the opening 14 to be distributed over the surface of the fuel in the heating-chamber and in an area largely in excess of the area of the delivery-opening 14. When the rotation of the coal-distributer stops, the flow of coal from the reservoir 6 is then checked by reason of the coal resting upon the disk 26 being held within the angle of repose.

What I claim as my invention, and desire to secure by Letters Patent, is- Y l. In a gas-producer, the combination with the heating-chamber having an opening at its top for the admission of fuel, of a fuel-reservoir placed above said opening` and having an opening in its bottom for the delivery of fuel to a distributer, a distributer' between the opening in the heating-chamber and the opening in the reservoir, said distributer consisting of a rotating shell smaller at its lower than at its upper end, with an opening at its upper end larger than the delivery-opening of said reservoir and concentric with its axis of rotation, and with an opening at its lower end eccentric with its axis of rotation, and a disk inclosed in said distributer having its diameter larger than the diameter of the delivery-opening in said reservoir, with an annular space around said disk for the passage of 6 5 tric with its axis of rotation, and with an opening at its lower end eccentric with its axis of rotation, and a disk inclosed in said distributer, having its diameter larger than the diameter of the delivery-opening in said reservoir, with an annular space around said disk for the passage of fuel.
