: FUEL CHARGER FOR GAS GENERATORS Application filed' July 17, 1929. Serial No. 378,875.

V with the operation of the gas set.

Oneobject of the'invention is to so construct the charger that-the fuel receiving opening of the generator nozzle normally will-be sealed and will be opened automatically when the with fuel. I v I Another object is to produce means for v automatically spreading the "fuel being chargedfinto' the generator 'toinsure proper distribution of'the fuel over the fire bed.

' Another object is to provide a movable fuel containerconnected with the charger and op'er'atively connected with the fuel spreading and generator sealing means, whereby the proper fco-ordinated' actuation ofjsaid parts is insured. The movable fuel container: has anopening for the reception V offuel from a 'cionvey'or," and closure means for said opening.

The closure means are also operatlvely connected with the generator sealing means so'that' said container door will be closed before the generator sealing means V is opened-and the fuel-contalner 1s moved to charging position. Thus, while the fuelcon tamer is movable relatlve to thech'arger' body, it is an integralpart thereof, and generator pressure is maintained the c harging period."

The design of the fuel hopper and nozzles leading fromthe hopperto the body of the charger is such that stop'page 0f ooal'or coke is prevented. The'mova'blehopper and nozzlefs render itpractical to usela low type'conveyor,foicarrying tlie fuelto the' hopper. p 7 The' meansffor spreading the fuel as it I i the generator opening, is operatively conenters the generator, also'acting as a'seal for ne'etedwith the fuel container,and the latteracts acounterbalance for the'spreader,

and insures the return of -the spreader to its sealing'p'osition when the generator is not being charged with fuel. This is of great j adva agebecausefshouldthe hydraulic pressur r g V I spreader ifa'il, 7 they spreader Wlll be returned to its closed or'tigh't position by the weight other means for operating the generator .is to be" charged even during ofthe hopper. Thereby the spreader is saved vision of operative connections between the spreader actuating mechanism and the mechanismvfor actuating the hopper door, which prevents thespreader disc being lowered beforethehopper door is closed.

1n the drawings;

'Figure 1 is a vertical sectional view of an automatic fuel charger embodying my invention, the; parts being shown in loading position.

FigureQ is a View similar to Figure 1, but showing the parts in charging position.

c Figure 3is a" plan view of the construction shown in Figure l.

Figure 4 is a horizontal sectional view taken on the line 4-4 of Figure 1, looking downwardly as indicated by the arrows.

Figure 5 is a vertical sectional view taken on the line 5-5 of Figure 2.

In that embodiment of my invention shown connected with the hop-* inthe drawings, 5 indicates a track on any cross section and tapering at 8 toward an opening adapted to fit over the opening in the top of the generator nozzle A.

' ,At opposite sides the charger body 8 is provided with horizontally disposed tubular extensions 9," in each of which is mounted one end of the rotatablenozzles 10 leading from V the hopper '11 to the charger body members 9.

2 The' inner surfaces of each of the tubular eXte'nsions 9 are provided with an annular shoulder '12 for the end-of the nozzle 10 to bear against and packing 13 between the extension incur her 9 and nozzle 10 to form a pressure tight fit between saidparts while permitting rotation of the nozzles in said tubular'ex'tension That part of thewall of the nozzle 10 which forms the side toward the left inFigures 3 and l, when the hopper is in loading position, and which forms th'elower or fuel support, ing wall portion when the hopper has been raisedtolchargingposition, as shown in Figure 2, extends atappro-Ximately a 45 angle to a horizontal plane, A semi-circumferential lip 10 is formed on theend of the nozzle 10, adjacentsaid inclined wall of the nozzle,

5 for the purpose of providing a concentric bearing surface on the nozzle for co-opera- 'Ition with the tubular extension 9 on the elmrger'body 8." Saidinclined portion of the nozzle wall has been designated aslOa and its form-is such thatwhen the hopper11 is in raised-position, fuelwill'slide easily over the inner surface of the hopper and nozzle, down-- wardly'and inwardly toward the charger body S' andthenceintO the generator nozzle A. When the hopper 11 is in raised orcharg ing position, the" surface at the lower .end of the nozzle, indicated at -10b, will be in alignmerit -with the, tapered surface 8;; ofthe charger body. This is best shown in Figure o-zfrom'which-it will ,be seen that'fuel willslide downwardly and inwardly over a smooth unobstructedsurface' nto the generator nozzle A.

; The fuel 'hopper 11 which is rigidly-secured i to one end of each ofsaid nozzles 10"has a' I division-plate :14 extending upwardly from "its bottom'wall 15 to a height indicated by 7 the line 16 in Figurel. This division plate .rll divides the hopper 11- into two passage ways, eachcommunicat ng with a' nozzle 10,

' and insures the equal distribution 7 of the fuel as itis being loaded into the hopper: v

Centrally located in the top wall of the hopper-11, that'is, at the junction of the legs 7 of'the' hopperand abovethe division plate -'14.-is-a circular opening 17 adapted to be The charger V 7 p 4 the? generator nozzle'Aywhen the carriage 7 closedby the sliding door '18.

I 1A fuel conveyor is indicated TatlQ, and

a conveyor oh ut'e at d3, the latter being pivotally'mountedon a' shaft 44 on which is also mounted a lever 45 havinga counterweight. 46 on one of its arms. 'An arm 473cm thehop "per 11 alternately contacts-with the chute- 43 and the lever 4C5 for, lowering and raising tliejchute. Thus the chute is raised by the hopper arm47and the way is cleared for the hop-per" to assume charging position.

The operationof the device is as follows The hydraulic cylinder 28 isv operatively' connected withfthe control mechanism of a conventional blue-gas or water gas set. Nor;

mally spreader "shaft 24' is in its raised positionlas shown'in Figurel' so that the spreader :disc 25is seated in theiop'e'ning in the tapered portion 84'ofthecharger body 8,

thereby sealing the generator nozzle opening. The hopperll and nozzle's 10;ar'efalso in theirv lowered positioniand in this position the door 18 forjthehopper' openingl'iiiiay-loe opened. This is accomplished, automatically by operative 1 connections between? the hy a c 9G wardly-to where its end s firmly secured to chopper acts as a counterbalance for facilitatnism of the set, or by. operative connections between the hydraulic cylinders 19 and 28.

The fuel may be loaded intothe hopper 11 by the conveyor 42 and chute 43 the latter being in its lowered position as shown in Figure 1;

The fuel being loaded into the hopper will be divided by the plate 14 and will be ready to slide downwardly through each leg of the hopper to the nozzles 10; I

' At a predetermined time the hydraulic mechanism will actuate the spreader shaft 24, whereby-the spreader disc willbe lowered, the ends of the cables 31 attached to the bracket 'will be drawn downwardly with the shaft 24, thereby raising the hopper 11 but first the hopper door 18 will have been closed so that pressure within the generator will .be maintained during the charging pe-' riod. The raising'of the hopper 11' causes the nozzle 10 to have rotative movement in the tubular extension members '9 of the charger body'8 and bring the inclined walls 10a toward the bottom, and the fuel will slide freely downwardly and inwardly through the nozzles,vand through the charger body to the curved upper surface of'the spreader 25 by which it is distributedfover the fuel bed. I

When the charging operation has been completed thejspreader will be 1 automatically raised by the hydraulic operating'cylinder 28 which is operatively connected to the control mechanism, of the gas set and the hopper and nozzlesfwill beflowe'red. The

ing the hopper.

' Evenif the hydraulic pressure the-cylinder 28 should fail, the weight of thehop- I per, 1by 'assunn'ng its lowered position and through its operative connections with the spreader would insure retaining the spreader shaft 1n its raised position and consequent I sealing of the generator opening by the disc "25. "The position of the hopper readily indicates to the operator the. position of the disc 25; in r- Instead of using a hopperll having two 1 legs and two nozzles,'each rotatably mounted in a tubular extension .9, it is feasible to I use'a single hopper,the nozzle of which may bemovably mounted'in the charger body 8 so as to be capable of being raised and low- 7 'eredfby the same kind of mechanism used connection with the twinnozz'les. I 'this'connection, it will alsobe understood that the operative connection between the hopper and spreader shaft 24 may comprise any suitable gearing which maybe substituted for the cable connections or .for the hydraulic operating cylinder and cable con- 'nection's;
