Description

'LLBL A. MCB. DUCKHAM. DISCHARGING VERTICAL HETOHTS.
PPLIICATION FILED MAY19|9S5 Patented Jan. 2,1917.
I ARTHUR Mcnon'eALL micxnm, or eener-neo, ENGLAND.
DISCHARGIN'G VERTICAL `Rlil'llOllEt'lS.
To all whom it may concern:
Be it known that I, An'rrrnn MGDOUGAIAL DUCKHAM, a subject of the King of Great Britain, residing in Ashstead, Surrey, England, have invented certain new and useful Improvements in Discharging Vertical Re torts, of which the ollowing'is a specification.
The well-known dischargingdevice of the Woodall & Duckham vertical retort comprises a retort extension having a. curved side and terminating infsubstantially gas. tight hopper from which the coke is withdrawn by eriodically opening a .curved Specication of Letters LPetent.l
waterseale door (f inthe`accompanying.
drawing), and avtoothed roller mounted t0 rotate continuously on a horizontal axis at t the foot of Ithe curvedside.
In one of my systems ofcarbonization in vertical retoits I-apply a constant mechanical pressure to the fcharge in the retort, so
thatthe discharging roller has to support not only a part of the weight of the char e but also the saidv mechanical pressure. t follows that the teeth of the roller have to move against a veryl 'considerable pressure which not only damages them lbut inc the consumption of power. To. avoid his objection the present invention substitutes for theJ roller as a feature of the combination an endless chain belt traveling over two rollers. -In this manner there is obtained the incidental advantage that the necessary supportin' in a smaller space than is possible when a rollei` is used. An'endless chain belt traveling on two rollers is not new as a device for' discharging a vertical retort, and no claim is herein made for such/a belt per 86.
The accompanying drawing, which is ar vertical section through the bottom extension of the retort a and the discharge hopper b, illustrates the invention.
The chain beltc extends around the continuously rotating rollers d, its engageses surface maybe accommodated and the like.
curved side e of the retort extension, it su have a substantially continuousv surface so that its links are best constructed to vtit into Patenten aan. e, rea.; y Application led May 19,' 1915. Serial No. a9, 147. l
each other in the manner usual' in the construction of underfeed stoking ap eratus This feature and a so the` mode of engagement of the belt with pins,I`Y`
on the rollers being well-known to enginee'rsg'gf are not here further described.
(The present invention is shown andy-Stile f ,scribed, but'not claimed, in my cfa-pendingl application Serial No. 29,145.
Having thus described my invention.' and the best'means-I know `of carrying the same into practical effect, I claim Apparatus for discharging vertical retorts in which a' positive mechanical pressure isa imposed upon the charge therein, compris;` ing, in combination, a substantially-vertical extension on the retort disposed directl below the open bottom thereof and embo Aying .a' curved sidewall which extends inwardly and downwardly from one side wall of said bottom to a point substantially inline with .the opposite side. wa11so as to sustain a portion ofthe weight of the charge; an endless chain belt'disposed` at the foot of said wall' and having one en'd overhung bythe same, so'as to sustain the remainder of the weight of the charge; land means for driving said .belt'in adlrection to` venable it to discharge continuously at its opposite end the charge which it supports.
