MEANS FOR RECEIVING AND DISCI-IABGING COKE FROM GAS-RETORTS.

Specification of Letters Patent.

Patented July 3, 1917.

Application filed July 16, 1913. Serial No. 779,237.

To all whom it may concern:

Be it known that we, WILLIAM H. GART- LEY and STEPHEN P. M. TASKER, both citi- Zens of the United States, residing, respectively, at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and at VVynnewood, in the county of Montgomery and State of Pennsylvania, have jointly invented certain new and useful Tm provements in Means for Receiving and Discharging Coke from Gas-Retorts, of which the following is a specification.

The principal objects of the present invention are to provide for receiving the coke as it is discharged from any of the retorts and for distributing it or any desired part of it at once or at any convenient time to the producer of the retort in which the coke was made or to some other producer or to a buggy or buggies wherever located or to a quenching hopper or onto any desired part of the lower floor; to prevent expansion and contraction of the setting from interfering with the proper ope-ration of the means or mechanism employed for carrying out the invention; to provide for the convenient and inexpensive renewal of the parts of the apparatus employed; to provide for the operation of the device even though some of the retort doors be open while at the same time preventing spilling of the coke against the front of the bench; and to protect the operator from heat while at the same time enabling him' to use appropriate tools upon the coke in case the coke binds or sticks.

The invention will be claimed at the end hereof but will be first described in connection with the embodiment of it chosen from other embodiments for the sake of illustration in the accompanying drawings in which- Figure 1, is a side view, partly in section, illustratingmeans or mechanism embodying features of the invention.

Fig. 2, is a similar view but with the section taken in a different plane and someof the parts in different positions.

Fig. 3, is a front view, and

Fig. 4, is a top or plan view.

In the drawings 1, is a platform-car or carriage movable up and down in front of retort benches This platform-car or carriage is arranged above thelower floor or cellar 3, and above the charging holes or openings 4., of the producers 5, of the retort benches 2. One of the rails 6, for the platform-car or carriage 1, is supported by the buck-stays 7, of the setting and consequently this rail may shift somewhat as the setting expands and contracts by reason of changing temperature. The other rail 8,is carried by some suitable support 9. Of the carrying wheels for the platform-car or carriage, the wheels 10, which run on the rail 6, are flanged and the wheels 11, which run on the rail 8, are not flanged but are of comparatively wide tread. Thus the wheels 11, may shift endwise on the rail 8, and permit the rail 6, to move somewhat by reason of expansion and contraction due to heat. In this way the clearance between the front of the retort and the parts of the moving carriage remains fixed. 12, is a motor shown as an electric motor and it drives the carry ing wheels of the platform-car or carriage l, for example by means of the gearing 13. Thus the platform-car or carriage can be run up and down in front of the benches and stopped in any position desired. The platform-car or carriage 1, carries a hopper 14, which receives coke pushed from a through retort, as is well understood, and by means of gates 15 and 16, either retains the coke for future delivery or else delivers it in whole or in part by either the chute 17, to the'producer opening 4:, or by the chute 18, for example, to a buggy 19, or to any part of the cellar or lower floor 3.: The hopper where it faces the retort bench is open and it is provided with an intake portion 20, arranged below the retorts of the lowest tier. The rest of the hopper is spaced so far away from the front of the bench that even if the retort doors are open the hopper will not strike them as it travels in front of the retorts. 21, is a guide consisting of side walls spaced apart and provided with a front plate 22, hinged at 23. The guide itself is hinged at 24. The guide 21, and the front plate 22, may occupy the retracted position shown in Fig. 2, in which position they are held by a chain or the like 25. It is evident that in this position there is sufficientspace in which the retort doors of the lowermost tier may stand open without being struck by any part of the moving platform 1, or parts carried thereby. The guide 21, may occupy the projected position shown in Fig. 1, and in this case the doors of the upper tiers'may stand open without being struck by any part of the moving platform or parts carried thereby. Rising from the platform-car or carriage 1, are standards 26, which constitute a frame that carries the various parts of the hopper and also the guide 21, and the pulley 27, for the chain 25. The hopper is made in three sections a, b and 0, so that when worn, its parts can be readily renewed. 28, are hand levers connected with the gate 15, and by which the gate can be moved into the positions shown in Fig. 1, or Fig. 2. 29, is a stop for the gate and it is arranged to arrest the movement of the handles 28. As shown the gate 15, is of the undercut variety as are also the gates 16. The latter are shown as geared together by meshing toothed sectors h, of which one is provided with a lever 30, connected by a link 31, with an arm 32, fast with the hand lever 33, so that the gates 16, can be opened and closed by means of the hand lever 33. The heat of the coke is retained in the hopper which is suitably constructed for that purpose and in this way the operator is protected. 34:, is a double doored opening through which the operator may insert pokers, rakes and other tools, if-

necessary, and through which he can observe the passage and delivery of the coke. 35, is a doored opening through which slicing bars and other tools may be inserted in order to loosenor break up any solid mass of coke that may have formed by chilling when the coke is retained in the hopper for a suffieient period of time. 36, is a stand depending from the platform-car or carriage 1, and adapted to accommodate the operator when it is desired to have access to the producer opening 37. 7

The'mode of operation of apparatus em bodying the invention may be described as follows: The operator or operators riding upon the platform 1, brings the hopper into position in front of the vertical row of retorts which are to be discharged in the well known manner by pushing the coke through from the other end of the retorts. In discharging a retort in the lowermost tier the guide 21, is in the position shown in Fig. 2, and the mass of coke d, is pushed from the right intothe intake 20. If the gate 15, is in the position shown in Fig. 2, the coke is discharged through the chute 17, and opening 4:,directly into the producer. If the gate 15, is in the position shown in Fig. 1, coke may not reach the producerbut is delivered into the hopper. If the gates 16, are closed the coke will remaih in the hopper butif they are open the coke will be delivered through the hopper, for example to the buggy 19, or other suitable receptacle. If the coke is retained in the hopper, the platform 1, may be moved and the coke afterward discharged at some convenient point. The fact that the coke can be retained in the hopper is advantageous because it protects workmen on the floor 3, from having hot coke accidentally dropped upon them. If coke is dis charged from one of the retorts in the upper tiers the guide 21, is put into the position shown in Fig. 1, and the coke is discharged through the guide and thence into the hopper which is operated in the manner above described. The front plate 22, of the guide as well'as the sides prevent coke from reaching the front of'the setting and insure its proper delivery into the hopper. The operators make use'of the doored openings 34 and 35, in the manner and for the purpose above described as may be necessary. By properly manipulating the gates 15 and 16, it is possible to direct all or any part of the coke through either of the chutes 17 and 18, or to retain the coke in the hopper for subsequent delivery at some convenient place. Frequently the charge of coke from a retort is more than is'required for the producer. In suchcase after the proper quantity has been delivered by the gate 15, into the producer furnace the gate is shifted, cutting off the flow to the producer furnace, and automatically directing the flow into the hopper. In this connection it may be remarked that the machinery for pushing the coke out of the retorts operates in such a way that when the coke starts to come out of the retort it continues to come out until the retort is empty.

In further explanation of the advantages obtained by the employment of this invention, we call attention to the following: The method of construction and operation there in employed, which method provides an open space 39, in the working floor 38, along the entire face of all the retorts, (Fig. 4),

through which hot air and fumes may freely V escape upward from the cellar below by convection along the front wall of the retort setting, insures the ventilation of this cellar, thus greatly increasing the comfort of men there employed and increasing the efiiciency of their work. This method also permits the operator upon the platform 1, or upon the stand 36, to at all times see into the cellar beneath and witness and control the discharging of coke and other operations'there occur-ring, thereby increasing the safety of the men there employed.

It will-be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction and arrangement, without departing from-the spirit of the invention, hence the latter is not limited further than the prior state of the art may require, but

Having thus described the nature and objects of the invention, what we claim as new and desire to secure by Letters Patent is:

1. Means for receiving coke discharged from gas retorts and for distributing the ,same which comprise the combination of a traveling hopper open for the reception of a charge of coke and provided with discharge chutes arranged respectively to discharge into a producer opening and at a lower floor, with gates for said chutes and with a movable guide having a front wall for use in connection with retorts of the 'upper tiers, substantially as described.

2. Means for receiving coke discharged from gas retorts and for distributing the same which comprise the combination of a traveling hopper provided with a depending chute and with a chute arranged to discharge into a producer opening, and an undercut gate for the last named chute and adapted to swing into the hopper to open the last named chute and direct discharge thereto.

In testimony whereof we have hereunto signed our names.
