COKE-DRAWINQ-MACHINE.
SPECIFICATION forming part of Letters Patent N 0. 728,102, dated May 12, 1903.
Application filed August 14,1902.
To all ivhom it may concern: I
Be it known thatI, JOHN A. HERB, a cititown, in the county of Fayette and'State of Pennsylvania, haveinvented certain new and useful Improvements in Coke-Drawing Machines, of which the following is a specification, reference being bad therein to the accompanying drawings, forming part of this specification.
Figure 1 is a plan view of my improved in front of an oven-door, portions ofthe con-3' veying mechanism being broken away. Fig. 2 is a vertical longitudinal sectional view on the line II II of Fig. 1. Fig. 3 is a similar view at right angles to Fig. 2 indicated by the line III III of Fig. 1. Fig. 4 is'adetail View of the vertical clutch mechanism of Fig. 3 and its operating-lever at right angles to the other figure. Fig. 5 is a vertical sectional View on the line V V of Fig. 2'looki'ng in direction of the arrow.
My invention relates to apparatusfor drawing coke from the oven, wherein a traveling structure is provided with a reciprocating beam having a rake-head adapted to beextended into and Withdrawn from the oven to empty the'contentstherefrom.
The present application refers more particularly to the means for raising and lower-- ing the operative end of the rake-beam.
Related subject-matter is embodied in separate applications bearing the Serial Nos. 119,617, 119,618, 119,620, 120,559, and 125,644. Referring now to the drawings, 'A repre' sents the framework of a portable carriage carrying the turn-table B, upon which are mounted the various manipulative portions of the machine. Mounted in suitable bearings is a main shaft 4, driven at one end by a suitable prime mover, as a steam-engine or electric motor. Centrally mounted in stepboX 6 is a vertical shaft 7 in driving engagement withthe shaft 4 by bevel-gears 9 10, by which shaft? is continuously driven. The
beam supporting and beam manipulating (longitudinally) framework and mechanism is mounted on the two main standards 22 22 at each side ofthe central shaft 7, which 'rections. side is a surrounding friction-sleeve 40, each standards are secured to the upper side of the $erial No. 119,619. (No model.)
turn-table and are provided at their upper portions with pillow-blocks or bearings 23, in which is mounted the cross-shaft 24, provided at its middle portion centrally above the center of the machine with driving-pinions 25 in driving engagement with racks 26, secured to beam 27, the center web of which extends between pinions 25 and'rests'. upon a roller 28, journaled on shaft 24, by which the weight of the beam is carried and the teeth relieved from the strain of gravity.'-
d On each side of'the beam, freely journaled on shaft 24, are the conical friction-drums 36, provided on their innerportion with periph- 'eral bevel-teeth 37, the teeth on both of such drums being in constant engagement with a driving bevel. gear-wheel 38, secured to the upper end of shaft7, by which both' frictiondrumsare constantly driven in opposite di- Beyond the friction-drums at each of which isprovidedwith a hub portion in driving engagement with the shaft 24 by spline or key 41, so that when either of such sleeves is brought into frictional engagement with the drum by shifting it'upon the shaft it will transmit movement to the shaft 24 in one direction'or the other, according to which drum is utilized, and thereby through pinions 25 and rack 26 will impart forward or back movement to the beam.
The shifting operation is secured through lever 42, pivoted at 43 and connected at 44 to a shifting bar 45, mounted in suitable bearings onnprights'22 and provided with forks 46, engaging collars or flanges on the hubs of sleeves 40.
The forward end of the beam is provided with a pivotally-attached rake-head 3l,adapt- 0 ed to fold backwardly when coming intocontact with the coke on entering theovenand to be automatically extended by tension of'a spring 32 at the back end-of the beam and connected to the rake by rod 33 and arms 35. 5
The inner end of the beam is raised and lowered by the rotation of shaft 47, the inner end of which is provided with abevel-gear 481 i in mesh with the upper and lower drivingbevels 49 and 50, loosely mounted on shaft 7160 and provided on their inner portions with clutches 51, with which is adapted to engage a vertically-moving clutch 52 in key or spline engagement with the constantly running shaft 7.
The clutch 52 engages with clutch of bevel 49 or 50 and is raised or lowered by lever 53 engaging in a groove in the clutch, the lever being secured to shaft 54, mounted in bearings in the framework and provided with an operating hand-lever 55, extending upwardly and within easy range of the operator.
For the purpose of maintaining the lever 53 and clutch 52 in their normal middle inoperative position shaft 54 is provided with a short arm 56, upon the outer end of which is hung a counterweight 57 by slot 58, elongated downwardly below the end of the arm.
The counterweight slightly overbalances the lever 53 and the suspended clutch 52 and rests on the turn-table, as shown. When the clutch is thrown down, the weight 57 is raised from its bearing, and when the clutch is thrown up the arm 56 passes freely down through slot 58, the clutch 52 tending to make its fall by gravity to the normal middle position illustrated.
:. and'provided with an extended lever-arm 62.
Upward ordownward movement of the inner end of the beam is imparted to it by arms 63, pivoted to lever-arm 62, carrying an under roller 65, upon which the beam rests, and by supplemental links 64 an upper roller 66. Links 67,pivoted at 68 in upwardly-extending guiding-extensions 69, maintain arms 63 and the supporting-roller in an erect position during the raising and lowering movements of the beam. By this mechanism the beam is capable of being raised or lowered or held in any position, and positive downward pressure may be exerted upon it to force the rake into the coke to facilitate its entrance during the rapid reciprocating movements imparted to the beam and rake by quickly alternating the engagement of the clutches 40, already described. The beam-supporting framework just described is located between the pivotal support of the beam and its outer end, thus placing the support as nearly as possible to the rake-head, where it may exert the greatest leverage. By this same. mechanism-to wit, pinions 25 and rack 26-the beam is thrust into or withdrawn from the oven, and such movements maybe accomplished while the rake-head is being raised or lowered when the rake is not in engagement with the coke, the operation being simultaneously performed with lever 42 in the left hand for operating the clutch-sleeves 40 and lever 55 in the right hand.
The operation of raising and lowering the beam will be readily understood from the foregoing description. It will also be understood that changes and variations may be made in the specific details by the skilled mechanic without departing from the invention, and all such are contemplated as within the scope of the following claims.
What I claim is 1.
