Specification of Letters Patent.

Patented Sept. 10, 1918.

Application filed August 28, 1917. Serial No. 188,613.

To all whom it may concern:

Be it known that I, ALFRED D. CREssLER, a citizen of the United States, residing at lvashington, District of Columbia, have invented certain new and useful Improvements in Apparatus for Charging and Discharging Gas-Retorts, Slots, and Chamber- Ovens, of which the following is a specification.

My invention relates to an improved and novel apparatus for charging and discharging gas retorts, slots, and chamber ovens, in the manufacture of coal-gas, coke and byproducts.

The main object of this invention isto provide simple, strong, durable, economical, novel and thoroughly efficient devices for the charging and discharging of gas retorts, chamber ovens, slots and the like, when positioned horizontally or in an inclined position, said charging being performed simultaneously with the act of discharging, and the said retorts are charged and discharged in series.

A further object of the invention is to furnish means whereby the respective bench capacity is increased by filling substantially the entire area of each retort during the charging operation.

A further object of the invention is to furnish means whereby the respective bench capacity is regulated by charging each series of retorts with a predetermined quantity or weight of coal, uniform and level throughout the full length of each retort between the inside surfaces of the front and rear arch walls.

Another novel object of mydnventionis to increase the carbonizing capacity of each gas bench of a predetermined area over present standard carbonization methods by charging each retort with coal to substantially its full area by means of an equalizing and charge regulating core and plunger and pusher, which conveys the coal and pusher from a series of .magazines into the retorts and by reversing the action of the plunger, the core is withdrawn from the retort, causing the coal to settle from the top providing ample area in each retort for outlet of gas and expansion. of the coal during the process of carbonization, the charge of fresh coal being delivered, each r t rt f th Series,

en massc, in one continuous uninterrupted operation and simultaneously with the discharge of coke.

Another object is to provide improved and novel devices which may be easily and readily manipulated by a minimum amount of labor, thereby constituting both a time and labor saving medium.

Another object of the invention is to furnish means whereby the act of charging and discharging of the retorts is performed in series and at the same time the charge-in each retort is regulated to meet the required conditions.

A further object of the invention is to couple each series of retorts with a single stand-pipe, also hydraulic mains on both front and rear of the bench of retorts or chamber ovens, and so arranged that the rich gases passing off during the early hours of carbonization are discharged through the stand-pipe at one end of each series of re torts and the lean gas made and passing off the last hours of carbonization and during the time the charge is held in the retorts to harden the coke is conveyed through the stand-pipes at the opposite end of the series of retorts, the hydraulic main being connected with a separate exhausted, condensing, washing and stripping apparatus; also a storage holder.

Another novel object is to provide charging means for maintaining the coal in each retort in such position as to receive the full force of the heat of the furnace throughout the entire length of the retort during the period of carbonization.

Another object of the invention is to so construct my improved devices that all gases generated will be saved during the process of 'charging and discharging each series of retorts. 7

A still further object of this invention is to provide a novel magazine pharging device arranged in series or singly, each magazine "being filled or charged witherushed coal while in a vertical position, then tilted to the proper discharging position and the seriesof magazines manipulated to enter the cast-iron mouth-piece of the series of retorts, in combinationxwith automatically operated means for discharging en masse the contents o the Series of azines ithin the e i s of retorts, and simultaneously discharging the coke from and cleansing the inner surfaces of each retort of the-series.

Another object of this invention is to provide a novel and simple horizontal coalcarrying and charge regulating core, fixed insideeach magazine, with a portable discharging device on the forward end, and a portable charge pusher in the rear, whereby the hot coke is discharged and the fresh charge of coal delivered into the series of retorts or chambers Without coming into contact with the coke, thereby preventing the making and wasting of gasduring the procass of discharging and charging the retorts or ovens,

Another useful and novel object of my invention is in the use of perforated steel disks, for the ends of the portable discharging device and eachpushing device, allowing a free passage of the gas at either end of the retorts to the stand-pipe. One disk on each pusher is also fitted with an adjustable scraping and shaving device fitting against thev inside surface of the retorts during the operation of each charge and discharge, and made of any suitable material, thereby pre venting the accumulation of carbon in the retorts. 1

Another novel object of this invention is to adjust only the front end of the steel magazine charging device the distance of the cast-iron mouth-piece and not its full length, into the inside of the retorts, during the process of discharging the hot coke and charging the fresh coal, thereby preventing damage, or destruction of the steel magazine.

Still another object is to provide a device for simultaneously filling the series of magazines with coal while in a vertical position direct from overhead charging hopper tubes, thentilting the series of magazines to a suitable discharging position to deliver the charge into the series of retorts, the discharging device being inserted into the front end of each magazine preventing the spilling of coal during the operation of discharging or charging the retorts or ovens during the conveying of, the series of magazines from the coal charging hopper tubes. WVhen the retorts are charged with fresh coal the end of the magazines extendinginto the cast iron mouthpiece and the solid disk forming the front of the portable discharge pushers effectively close the ends of the retorts thus preventing .the' first made rich gases from escaping into the atmosphere, but forcing such gases to be conveyed to the hydraulic main through the rear stand pipes, thereby increasing both the quantity and quality of the gas made and preventing the escape of thevapors into the air.

The foregoing and such-other objects as may appear from the ensuing descriptionare attained by the novelfeatrdes of construction, combination, location and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the claims appended hereto, it being understood that slight changes in the form, proportions and minor details of the construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Similar numerals of reference are em ployed to designate corresponding parts throughout the several figures of the drawings.

In carrying out this invention as illustrated and which shows a preferred construction, the numeral 1 indicates the front wall and 1 the rear Wall. of a coal gas oven, said oven being provided with a bench of nine horizontally arranged retorts or chambers 2, arranged in series consisting of three retorts or chambers to each series, each series being connected or coupled with a single upright stand-pipe or ofi'take 3 for conveying the to the hydraulic mains 4:, at each end of the bench or stack of retorts, and being-so arranged that the rich gases are carried away through the stand-pipe at one end of each series of retorts'or chambers, and the lean gas is conveyed away by the standpipe at the opposite end of each seriesof retorts or chambers, as clearly shown in Fig. 1 of the drawings. While I have shown a bench of nine retorts or chambers arranged in series of three each coupled together in vertical alinement, each of the series of retorts being charged and discharged simul taneously, it will be understood that any suitable or desirable number of, retorts or chambers may be utilized, and any suitable number of the retorts may be coupled inseries or arranged singly for simultaneous charging and discharging, and if desired the retorts or chambers may be arranged in an inclined position instead of the horizontal position as shown. j V 7 Each of the retorts or chambers is provided at one end with a mouth-piece or-en- 'trance-n iember 5 provided with a'gas discharge opening 6 leading to the off-takeor stand-pipe, and at the other end with a-discharge or exit member 7, having a gas discharge opening 8 leading to the off-take 3, each retort or chamber being suitably supported in the gas oven, and provided at each end with any well-known construction of coveror lid. 1 '1 f Arranged parallel with the bench of retort/S or chambers at their entrance ends, and

movably supported on track rails supported by the flooring or a suitable platform, is a portable magazine charging and discharging carriage, comprising a truck member or frame 9, supported by wheels 10 said frame having secured thereto two upright transversely arranged members 11., each member having a centrally arranged recess in the upper longitudinal surface in which is secured a rail 12, adapted to slidably support a pivoted or swinging frame 13, provided with a member 14 at each side thereof adapted to be slidably supported on the rail 12. Suitably and rigidly secured in a horizontal position .to said frame 13 in vertical alinement, is a suitable series of coal carrying magazines 14 and centrally secured to the frame 13, at each side thereof, is a lateral extension 15 adapted to form a bearing socket for the frame pivotal pintles or stub shafts 16, which rest within and project be yond the said sockets. Suitably secured to one side of the frame 13 is a metallic plate 17, having a notch 18 formed in its peripheral portion adapted to receive and engage the locking member 19, carried by the hand lever 20 secured to the pivot pintle or shaft. 16, and adapted to lock the series of magazines when tilted by the said lever into the vertical position, as shown by dotted lines Fig. 2.

Rigidly secured to the frame 9, are two upright brackets, in which is supported a tubular sleeve 22, provided with an internal.

screw-threaded end portion 22 adapted to engage with a screw-threaded rod 23, which is secured at one end to a bar-.24, the latter being pivotally secured to an upright lever bar 25, pivotally secured at its lower end to the frame 9, and at its upper end to a horizontally extended bar 26 secured to the pintle or shaft 16, and suitably secured to the frame 9 is a metallic upright member 27, provided with an opening 28 adapted to receive and support shaft 29 provided at one end with a bevel gear-wheel 30 engaging with a bevel gear wheel 30 supported by the bracket 21, the other end of said shaft 29 being J provided with an operating handle 29, as shown in Figs. 2 and 3, which handle when manipulated to the right or left causes the frame with its series of magazines to slidingly advance and the in agazines to enter the mouth-pieces of the series of retorts for the charging and discharging operation or to slidingly move away, respectively, and be disengaged from the retorts for the purpose of moving the magazine carriage" into the proper position for. another charge;

The magazines are each provided with a metallic equalizing or regulating core bar 31 for properly and suitably regulating the charge to be forced into the retorts or chambers, said core-bar consisting-of a horizontal member 32 and a central depend g member 33, and being provided at its outer end portion with an integral disk 34 adapted to snugly fit the interior surface of the magazine wall and close its outer end, which disk has rigidly secured thereto or integral therewith at its central portion an outwardly projecting annular solid metallic member 35, which passes through an opening 35 formed in the inner end wall of the magazine, said member 35 having an annular notch 36 formed therein, and a cone-shaped outer end 37 for the purpose hereinafter described. Projecting outwardly from the peripheral portion of said disk 34 is a member 38 adaptcd to engage a recessed or slotted portion 39 formed in the inner end wall 39 of the magazine which serves to prevent any rotary movement of the said core-bar, and each magazine is provided with an inwardly 'ex tending longitudinal metallic guide plate 40, suitably secured thereto, which plate 40 is straddled by the plates 41, one secured to each side of the central member 33 of the core-bar, thereby serving as a true guide for the core-bar in its reciprocating back and forth movement during the charging and discharging operation of the retorts and its withdrawal and preventing any wabbling or sidewise movement of said corebar.

A core-bar is normally secured in eachmagazine and when it is desired to fill the magazine a charge pusher is passed over the outer end portion and caused to assume a position against the disk 34, as shown in Fig. 4 and by dotted lines Fig. 8, said charge pusher comprising two perforated metallic plates' 42, each provided with a horizontal slot 43, and a vertical slot 44, so that the pusher may be slid over the corebar to the rear end-portion thereof, said plates being provided with a series of openings or perforations 45 therethrough to permit the escape of gas, and being secured at a suitable distance apart by suitable threaded bolts 46, and nuts 47, as clearly shown in Figs. 10 and .11. have been properly filled with the measured charge of coal, a portable discharge'pusher consisting of two

metallic plates

42 and 43 is inserted in the front end of each magazine in contact with the core bar and coal, said platesbeing connected together with suitable bolts and'nuts such as are used in connection with the charge pusher hereinbefore described, the rear plate 42' being provided with suitable openings or perforations for the escape of gas therethrough, and having a vertical slot 44, 'to permit the discharge pusher to be slid over the reduced front end portion 31 of the core-bar, as shown in Fig.

-4, and the said rear plate 42 is provided with a plurality of adjustable scraping blades 45, each blade having an elongated slot 46 therethrough adapted to receive a suitableadjusting device 47, as shownin After each ma azine of the series shall" Fig. 16, whereby the said blades may be so adjusted as to scrape and clean the inner surface or wall of the retort as the discharge pusher is forced from the front to the rear thereof, while the front plate of the discharge pusher is made of a solid plate or disk 43. Thus the front plate and scraping blades serve to push out the coke, and clear the gas retort or chamber simultaneously with the charging of the retorts or chambers with a fresh supply of coal.

Arranged parallel with and at one side of the magazine carriage, is a portable motor carriage supported on rails secured to the flooring or a suitable platform, said motor carriage comprising a frame 48, supported on wheels 49, and said frame supporting a series of cylinders 50, each cylinder being provided with a reciprocating plunger 51, and each plunger having secured to its forward end a spring-operated pivoted lever 52 provided with a catch or latch 53, adapted to engage the annular notched portion 36 of the member 35 carried by the rear end of the core-bar 31, with the end 37 of the member 35 resting within the tubular end portion 54, and against the solid end wall 54 at the outer end portion of each plunger. Suitably connected to the frame 48 at each side thereof is properly arranged a compressed air supply pipe 53 and an exhaust pipe 54, each supply pipe and exhaust being connected to the said cylinders by the manifolds 55 and 56 at each end of the cylinders, a shutoff valve 57 being arranged in each supply pipe, and a valve 57 in each exhaust pipe, each valve being provided with an arm 58, to which arm is pivotally connected a bar 59 to which bar is secured an operating lever 60, the precise construction and arrangement of the parts being the same at each side of the carriage and by the proper manipulation of said lever the air supply to the cylinders is controlled and the series of reciprocating plungers moved into proper alinementwith the filled or charged magazines and coupled with the outer end of each core-bar, the outer solid end portion of each plunger engaging with the cone-shaped projecting portion of said core-bar and the plungers automatically projected forward, thereby discharging the series of filled magazines into the series of retorts and simultaneously discharging and cleaning out the series of retorts or chambers, after which the withdrawal or return movement of the series of plungers simultaneously withdraws and returns each core-bar to its normal position within each magazine to continue the oharging and discharging operation, as is clearly shown in Figs. 4 and 5 of the drawings.

Referring to Fig. 7 will be seen a storage bin or bunker 61 having a hopper-shaped bottom portion 62, provided with a series of depending discharge tubes 63, Which tubes mouth-piece of the retort.

are adapted to measure and discharge into the magazines supported on the magazine carriage and arranged in vertical alinement with said discharge tubes, a suitable and predetermined quantity of coal to constitute the most desirable and effective charge for properly filling or charging each of the gas retorts or chambers.

It will be seen by reference to Fig. 12 that the mouth-pieceof each retort is provided with a gravity catch or retaining latch 64 which serves to prevent the accidental withdrawal of the charge pusher from the retort during the withdrawal of the core by the operating plunger 51, the disk 34 being provided with a slotted portion 65 which permits the core to freely pass the said catch, and the outer end of each magazine is provided with a suitable slot 66 to prevent in any manner the engagement of the ends of the magazine with the said catch or latch 64.

lVhile I prefer to utilize my improved charging, discharging and cleaning apparatus in connection with cylindrical or tubular retorts or chambers, it will be readily obvious that by making slight changes in the shape or contour of the several members employed the apparatus may be readily utilized for the charging, discharging and cleaning of any shape of retort or chamber now in use in the manufacture of coal gas, coke and by-products.

It will be perceived by reference to Figs. 1 and 4, that the charge pusher provided with its perforated end plates is 'so positioned in the retort as to occupy only the space which is surrounded by the front oven wall 1, while the discharge pusher and cleaner provided with a perforated rear end portion and a solid front portion occupies a space in the retort surrounded by the rear wall 1 and the discharge or exit member 7, the entire charge of coal being held intact between the outer end of the charge pusher and the inner end of the discharge pusher in such position as to subject the full charge of coal to the entire heat of the oven, the end of the magazine being entered into the The gas generated from the fresh charge of coal is carried off through the rear stand pipe thus preventing the wasting of the same into the atmosphere as is now customary by the present methods employed, thereby increasing both the quantity and quality of the gas.

I desire it to be' understood that the charge is equalized and regulated by the size of the core employed in connection with each charging magazine, since a core of predelei-mined dimensions may be utilized so as to fill each retort to its full capacity and at the same time allow for the expansion of the coal within the retort, and sufficient space for the escape of the gases at each end of the retort when the coreis withdrawn from the loaded retort back into the empty magazine.

Further, it will be understood that any "suitable motive power may be employed for operating the plungers carried by the portable motOr carriage, as well as the tilting and slidable frame carried by the portable magazine carriage.

The operation of my improved apparatus briefly described is as followsz- Each of the coal carrying magazines which are pivotally supported and carried by a movable carriage, contains themovable equalizing and charge regulating core bar 31, and said carriage is moved to a position directly beneath the coal supply and said magazines tilted to an upright position the charge pusher is inserted into each magazine; the magazines are then properly filled with a measured supply of coal by means of the coal supply tubes shown in Fig. 7, and a discharge pusher is inserted into the end of each magazine with its inner end plate in contact with the coal; the said carriage is then moved into alinement with the retorts to be charged; the magazines being tilted into a horizontal position they are adjusted inwardly within the mouth-piece of each retort by the operating mechanism carried by the said carriage until the end of each magazine contacts with the end of each retort, when the motor carriage carrying the operating plungers is moved into proper alinement with the magazine carriage, and the outer end portion of each plunger is connected to the rear extension formed on each of the equalizing and charge regulating cores; the motive power being then applied the said plungers will be caused to move forwardly in unison thereby -causing the discharge pushers, the charges of coal and the charge pushers to move in unison into the position shown within the middle retort illustrated in Fig. i of the drawings, whereby the coke in the retort will be discharged simultaneously with the entrance of another charge of fresh coal into the retort; the motive power being then reversed the plungers are withdrawn carrying back with them the equalizing and regulating cores into their proper position within the magazine, and leaving the charge of coal within the retort, and the charge and discharge pushers in the position shown in the bottom retort as illustrated in Fig. 4.
