To all whom may i Q Be it knownlthat I, HERBERT JOHN T00- of Gas Retorts't-and' The present invention relates previous application for patent Serial No.

4192,0552, filed April 24., 1909.

According to my present 4 pose to deliver the coal to the retorts from a traveling hopper, truck, conveyor or other appliance through a movable chute, which 1 chute enters for a certain distance'into the mouthpiece and the retort -:in'"cliargii'1'g.

Upon the retort being filled up to the point at which the coal therein reachesand sealsf the lower aperture of the chute, the flow of coal down the chute is thereby stopped-until" the chute is raised. Such raising of th'e'chut'e then cuts oil the supply of coal tothe-upper I aperture of the-chute, and the said chute on 30 being raised em ties itself into the retort,

completing the merge. v

Where the coal is fed at one:side of the retort as described in my said prior. specifi- 'cation,'the lower aperture of the chute during the charging operation maybe inclined at an angle to the axis-of the retort, and'the: said chute in risingdelivers over. that part of the vretortnot previously filled thesmall qgiantity of coal remainin inthe said chute, t ejcapacity of the said c ute. being such as to regulate this quantity according to requirements. By this means, an intermit-' tently charged retort is made to act as its own measure, that is to sayit cannot be overcharged or undercharged, the charge being'automatically adjusted to the capacity of the retort. The importance of this will be obvious, as it is well-known that a retort when fouled with a deposit of carbon will hold less coal by say two or'three cwts. than when in a clean condition, that is, for example, after being newly scraped or scurfed. Also. if the traveling hopper be charged from overhead bunkers, and the door of such a bunker remain open during r 1 apparatus for use in connection w th e n; ventlon described in the specificatlon of my invention I pro fore charging.

: In order ,thatzmy said invention may be tice; -Figure 1 invention. Fig. 2 .is=a diagram illustratm a straight'chute moving verticall 13 an" elevation taken at'righ-t ang es to that in FigLB, the coke hopper 23 being removed.

The top. of the chute 5 is bell mouthe provided on three sides with an enlarged funnel or fence lO,'the remaining side being adapted to receive coal from an opening (not seen in this figure) at the bottom of the hoper 2. By rotating the hand wheel 8, the ellcrank lever arm 7 is drawn to the left so as to raise the chute 5, which works against the fiat face of the hopper 2, into the position shown in dotted lines, the chute thereby closing the outlet of the hopper and cutting ofi' the supply of coal, while during such rising movement the small quantity of coal contained in the chute is distributed over the sloping bank of coal shown in the retort in such manner as to approximately level up the charge of coal to the top of the retort. A separate hopper is or may be employed to supply the small quantity of coke usually dropped into the bottom of the retort be- -11 indicates the continuous storage bunkers, 12 a bell-crank lever for actuatin a sliding bar 13, which, by suitable catches,

Instead of employlng a bell-crank lever to effect the lifting of the chute 5, any other 5 suitable means may be employed,- as for instance a worm and wheel, the arm 6 being connected to the boss of theworm wheel.

*In the modification shown in the diagram 1 :Fig. 2, an inclined chute 5, when m the position shown in full lines, receives coal from" the hopper 2 through the opening'18. Upon the retort being filled up to the mouth 19 of 4 the-chute 5, the descent of coal ceases; and

. 'upon;the chute 5 being drawn backinto the. 20 position shown in dotted lines, the said chute 'acts as a slide door to close the said opening 18, while the coal contained in the chutefalls into the retort and completes the charge. 5 5

The two hoppers are suspended from .wheels 3 traveling on rails 4, and-for exact adjustment a chaindrive may 4 be operated from the hand wheel 26. The g strai ht chute 5 works in guides 27 onthe flat face of thehopper 2, and can be raised and lowered by operating the weighted hand lever 28; the'said chute is shown in full line at a a in Fig. 3 indicate the height at which dotted lines at b b the height thereof when receiving coke from the hopper 23 through the-outlet 29 of the latter. The same letters, a and b, in Fig. 4, refer to the dotted-lines showing the corresponding positions of the hand lever 28. The flange or web 30 on the chute engages the guides 27. The hopper 2 has an inclined extension 31 which meetsthe top of the chute 5 when in its lowest position, the coal being then free to pass down the inchute, but the oppositeside' of the chute is extended outward and upward as shown at 33, to a height approximately equal to that of the top of the opening 32, to prevent overflowing of the coal from the chute.

space. between the chute 5 in'its raised posi-- tion and the retort mouth piece, can be sufficient to allow of the retort lid being closed before'moving-the traveling hopper 2. 1 The door 20 in the bunker 11 is then closed, and, assuming the hopper .2 to contain sulfici'ent coal for charging'the next succeeding retort,

another door-20 in the bunker need not beopened until'the hopper reaches the retort In Fig.4 the underside of thechutei's side; but this formation, thoughdesirable tice of the present invention.
