MACHINE FOR DISCHARGING COKE-OVENSj.

SPECIFICATION forming part of Letters Patent No. 731,911, dated June 23, 1903.

i Application filed April 27, 1903. Serial No. 154,532. (No model.)

.To all whom it may concern.-

Be it known that I, J AMES ELLWooD J oNEs, a citizen ofthe United States of America, residing at Switchback, in the county of Mc- Dowell,in the State of. West Virginia, have invented certain new and useful Improvements .4 in Machines for Discharging Coke-Ovens, of

which the following is a speciiicat'ion.

rlhis invention relates to a coke-puller designed to be operatedby machine for pulling coke from coke-ovens, and it is particularly adapted for discharging coke from beehive coke-ovens. In the manufacture of metallurgical coke the oven known as the beehive-oven, so called because of its domeshaped form, has been generally adopted, being found to give the best results. In the burning of thecoke the coke is produced in a caked mass, having a vertical stratification,

and it is desirable to avoid as much as possi# ble breakage of the sticks and lumps extracted from the oven.

Theinvention consists principally in a cokepuller having an underworking or wedgeshaped scraper operating on the instroke into the oven to loosen thecoke for withdrawal and provided with adjust-able means operative on the outstrok'e for grasping or holding loosened coke disposed over and above Vthe scraper, wherebya thorough discharge of the oven may be obtained. t

The invention consists, further,in a cokepuller comprising an underworking scraper operative on its instroke to loosen coke for Withdrawal and means in the form of an up- Wardly-swinging` plate connected therewith and operative on the outstroke for holding the loosened coke over and above the scraper.

Figure l ofthe accompanying drawings repre'sents a side elevatiompartly in section, on

` line 1.1 of Fig.3 of one embodiment of this mechanicalcokepuller in connection with a coke-oven, a coke-car for receiving the coke i pulled from the oven, and a machine-car on which the pullerA is mounted,parts being broken out for convenience o f illustration.

Fig. 2 represents a transverse section on line 2 2 of Fig. 1.

Fig. 3 represents,on an enlarged scale, avertical transversesection on line 3'3 of Fig. l. Fig. 4 represents, on an enlarged scale, a side elevation of the coke puller proper, partly in section, on line 4 4 of Fig.

a part of the coke-puller and the coke-holding means in modified form.

The saine reference-numbers indicate the same parts in all the figures.

This coke-pulling apparatus may be used for discharging various forms of coke-ovens. The drawings represent fragments of a beehive coke-oven l0, provided, as usual, with atop opening, which serves for a feed and blast opening, and with a lateral dischargeopening l2. These openings are closed and sealed in the usual manner during the coking operation or a part thereof. A number of such coke-ovens are arranged side by side, and a railway-track 2O is disposed in front thereof, on which travel the coke-cars 30 for receiving and conveying away the coke drawn from the oven. Any other suitable means may be employed for disposing of the coke withdrawn from the ovens. A track 40 is disposed outside the track 2O parallel therewith,.and a machine-car 50, on which the discharging apparatus is mounted, travels on said track 40. A suitable frame for operating the mechanism of-the coke-puller proper is mounted on the car 50. The frame shown for this purpose comprises two standards 51 and 52, secured to the platform of the car at opposite ends thereof. These standards are connected by a top cross-bar 53 and provided, respectively, with horizontal shaft-bearings 5l and 55. '["he cross-bar 53is provided with a vertical shaft-bearing 56, and the car-platform is provided in line with the bearing 56 with a corresponding vertical shaft-bearing 57, having an exterior flange 58, adapted to serve as a stepbearing. The platform of the machine-car is also provided with standards, as 60, on one side and with standards 62 and 63 on the other side thereof. The rst two of the standards above referred to are connected by longitudinal rails 64; and 65, disposed parallel -with each other in alhorizontal plane about midway of the height of the main frame, and these rails form a guideway for the coke-puller,

as hereinafter described.

IOO

Corresponding rails 66 and 67 connect the standards 62 and 63 and form a guide at the other side for said coke-puller.

A horizontal driving-shaft 70 is supported in the bearings 54 and 55. This shaft is provided with a crank 71, a fly-wheel 72, and valve-eccentrics 73 and 74. Any suitable means maybe employed for imparting motion to the driving-shaft-suoh, for inst-ance, as a motorcylinder 80, disposed on the platform 50, the piston rodv thereof playing through a guide-bracket 82, attached to the frame, and being connected by a pitman 83 with the crank 71. This motor-cylinder is provided with a valve-chest 84 for the inlet and exhaust of the steam, air, or other motive fluid. This engine may be provided with any means usually employed for stopping, starting, and reversing, controlled, for instance, by a reversinglever 85. Two bevelpinions and 91 are disposed loosely on the driving-shaft. The innet` ends of the sleeves of said pinions are provided with clutch-faces of any suitable form. A clutch-sleeve is splined on said driving-shaft 70 between said pinions, and the opposite ends thereof are provided with clutch-faces adapted to engage said pinions respectively. An actuating-le-v ver 9G, suitably pivoted on the frame, is provided with a forked inner end which engages said clutch-sleeve, whereby the latter may be shifted into and out of engagement with either of said pinions for driving and reversing the mechanism operated by the driving-shaft and out of engagement with both said pinions for stopping said mechanism.

A vertical shaft is supported at its upper end in the shaft-bearing 5(3 and at its lower end in the shaft-bearing 57. A bevel gear-wheel 101 is fixed on the upper end of the vertical shaft 100 and meshes with both the bevel-pinions 90 and 91, loose on the driving-shaft 70. This vertical shaft is provided with two loose beveled pinions 102 and 103, disposed one above the other in reversed relation to each other, the sleeves or hubs thereof being provided with clutch-faces. Sliding clutches 104 and 105 are splined to the vertical shaft adjacent to said pinions, respectively, and adapted to lock the said pinions to the shaft. A clutch-lever 106 actuates the clutch 104, and clutch-lever 107 actuates the clutch 105.

A swiveling frame is mounted on the machinecar for carrying the coke-puller, which is thrust into and retracted from the oven in pulling the coke therefrom. This swiveling frame may be of any suitable construction. As herein shown, it comprises a sleeve 110, surrounding the vertical shaft 100 and supported on the step-bearing 57. Three curved arms or brackets 111, 112, and 113 extend upward from the upper end of said sleeve, the brackets 111 and 113 beingin the same diametrical plane and the intermediate bracket 112 being at right angles to the others. The brackets 111 and 113 are provided at their upper ends with horizontal guideways '114 and 115,1espectively, through which the cokepuller bars work, as hereinafter described. The intermediate bracket 112 is provided Withtwo horizontal shaft- bearings 120 and 130, disposed one above the other. Two stubshafts 121 and 131 are mounted'in these bearings and project toward the vertical shaft 100. A pinion-sleeve 122 is secured to the shaft 121 and provided with a straight pinion 123 and with a beveled pinion 124, and a pinionsleeve 132 is secured to the shaft 131 and provided witn a straight pinion 133 and a beveled pinion 134. The beveled pinion 124 meshes with the lower beveled pinion 102 of the vertical shaft, and the pinion 134 meshes with the upper beveled pinion 133 on said shaft, and motion is imparted to each of the stub-shafts in either direction by means of this gearing. The swiveling frame is oscillated by any suitable means. For this purpose it isshown as provided at the lower end of its sleeve with a worm-wheel 116, and a horizontal shaft 117, having its bearings in the stationary frame of the machine-car, is provided with a Worm 118, engaging said worm-wheel,and with an actuating-crank 119.

A coke-puller proper comprising a scraper adapted for loosening a portion of the caked coke on the instroke and having an adjustable cokeholder for grasping or holding the loosened coke over and above the scraper on the outstroke is mounted on and actuated from the swiveling frame. This coke-puller may be constructed in any suitable form which adapt-s it for performing this double function. In the form of embodiment shown in the drawings it comprises a shank-bar 140, a beveled scraper 150 at the outer end of said shank-bar, and a swinging plate 160,l which in this showing constitutes a part of the cokeloosening scraper, a slide-bar 170, and a flexible connection 180 between the slide-bar and the swinging plate. The body of the scraper 150, which may be solid or skeleton construction, is in the form of a wedge attached to the bar 140 and beveled downward from its thick rear face 152 to its thin front edge 151. The front edge is preferably arc-shaped to conform to the curvature of the oven-wall, and the rear faceis preferably straight and at an abrupt angle to the inclined upper face. This body is preferably provided on its under side with antifriction-rolls 153 and 154,which travel on the oven-bottom. The shank-bar 140 is supported in the guideways 114 and of the swiveling frame and also in the elongated stationary guideway at opposite sides of the machine-car, which lattervpermit the bar to swing horizontally to different angles as the supporting-frame swivels. The in= ner portion of this bar is provided with rackteeth 141, which engage the pinion 123, whereby said bar is reciprocated to thrust and re- IOO IOS

tract the scraper. This bar is provided in its outer portion at its upper side with a guide 142, and on one side with stops 143 and 144.

The swinging plate 160, constituting the front face of the wedge-shaped scraper, is hinged at its upper edge to the angle of the scraper-body. This plate also extends ina transverse directiontol the bar 140 and has a beveled outerIedge 161, adapted to the bonttom of theoven. This plate is provided on its upper face in line with -the shank-bar 140 with a lug 162, to which vthe outer end of the bar 140 and is somewhat shorter than the lat` This slide-bar also moves through the chain 180 is connected. This lng is preferably thin and tapering to permit it to pass readily through the coke and su fticiently highA to afford leverage for the actnatingmeans. The pintle ofthe hinge of the swinging plate 160 is provided with an antifriction-roll 164, over which` the chain passes.

' The slide-bar 170 is mounted on the shankter. guides of the swiveling and stationary frames heretofore mentioned and also at its outer end through the guide 142,attached to the bar This bar 170 is also providedalong its inner portion with rack-teeth 171, which are engaged bythe pinion 133, wherebymotion may be imparted to said bar independently ofthe motion of the bar 140. This slide-bar 170 is provided with adependent lug 172, which plays between the stops 143 and 144 of the bar 140, whereby the movementof the `sliding bar `170 is limited n The front end of the sliding bar is preferably beveled, so as to pass readily under the coke on the instroke.

'In Fig. 6 the swinging plate and actuatingbarare connected by the rod 190 and the links 191 and 192, the link-191 resting on the antifriction-roller 164 when the swinging plate is closed, or nearly so.

The machine-car may be provided with suitable traction mechanism operated b y the same power which operates the coke-puller.

This traction mechanism may consist of suitable transmitting-gearing between shaft 100 underneath the platform of the car and one of the axles thereof and will pro'perly include devices for shifting it into and out of gear, so as to move the car as desired.

In the use of this coke-drawing apparatus when the oven is ready to bedischarged the f n machine-@m and the receiving-car 30 are moved into position opposite the lateral ovenopening 12, the closure of which is removed. The engine is started, and the driving-shaft moves in the direction of the arrow 72 in lFig. 1.. The operator then by the lever 96 shifts the clutchl 95 into engagementwith the pinion and by the lever 106 shifts the clutch 104 into engagement with the pinion 102 on the vertical shaft 100. The cokepuller is thereby thrust into the oven, and the scraper thereof moves over the bottom of the oven asuilicient distance to make a proper drawing of the coke.

coke-puller the plate On this instroke of the 160, constituting the wedge to lift the coke above it beveled front face of the scraper, is in` lowered or closed position and operates as a from the caked mass of coke within the oven. At the end of the instroke the lever 106 is shifted so as to disconnect the pinion 102 from the shaft, and the inward movement of the coke-puller is stopped. Then the lever 96 is lnoved to shift the clutch out of engagement with the pinion 90 vof the driving-shaft and into engagement with the pinion 91 thereof, whereby the motion of the vertical shaft 100 is reversed. Thenthe lever 107 is shifted into position to lock the clutch into engagement with the pinion` 103, and motion is imparted to the pinion 133, which engages the bar 170, whereby said' bar is retracted a distance equal to the space between the stops 143 and 144 on the bar 140, and the swinging plate 160 is lifted into raised position, as indicated in dotted lines in Fig. 1. This upward swing of the plate 160 lifts the mass of coke immediately above said plate and thrusts it behind said plate and places the plate in position to engage the depth of loosened coke above the body of the scraper on the outward stroke. The operator then shifts the lever 106 and brings the clutch 104 into engagement with the pinion 102, whereby the actuating-bar is retracted and the coke-puller withdrawn from the oven, with its plate in raised position, whereby substantially the whole mass of c'oke which was loosened on the instroke is discharged into the coke-car 30. Then the levers 106 and 107 are shifted to throw both the gears 102 and 103 out of connection with the vertical shaft 100, whereby the motion of the coke-puller is stopped. To make another stroke, the vertical shaft 100 is reversed either by reversing the engine or by shifting the clutch of therdriving-shaft. Then the upper bar is first brought into operative connection with said vertical shaft and is thrust forward, loosening the chain and permitting the plate 160 to fall into closed position. Then the lever 106 is actuatedto connect the bar 140 with the transmitting mechanism, and the new thrust of the coke-puller is effected as before. The first few strokes of the coke-puller are preferably in a direct line at right angles to the tracks, it usually requiring two or more drawings to remove the coke throughout a diameter of the cokeoven. After this is done lateral thrusts of the coke-puller are made, iirst to one side and then to the other, the swiveling frame being shifted for this purpose by the operator through the manipulation of the crankwheel 119.

' It will be understood that the separate driving-gearing for the bar 140 may be omitted, if desired, and said bar operated through the driving mechanism for bar 170 and its connection with the 'bar 140. Other details of construction may be varied without departing from the scopeof this invention.
