Application filed March 26, 1915. Serial No. 17,289.
A salient feature of the invention is the provision in a ladle dumping car, of means for locking the ladlein upright position, whereby the same cannot be accidentally dumped to one side or the other, and said means being operable to allow the ladle to be dumped to one side or the other without the liability of the ladle dumping otherwise than as desired by the operator.
Another object of the invention is the provision of a locking mechanism of the nature indicated, which is ada ted to operate the pressure fluid valve of the cylinder, whereby the valve Wlll be operated properly according to the side to which the ladle is to be swung. In other words, the construction of the present mechanism is such thatwhen the locking means is operated to allow the ladle to dump to one side, the controlling valve is operated automatically to allow the pressure fluid to flow into the proper end of the cylinder, so that when the pressure fluid is turned on it will move the ladle to the proper side to dumping position.
Another object of the invention is the provision of novel means for operatively connecting the cross head and the adjacent trunnion of the ladle ring or carrier, where by the trunnion will be properly rolled upon its support when the cross head is recipro sated, for tilting the ladle ring or carrier elfectively.
With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
The invention is illustrated in the accompanyiag drawings, wherein Figure .1 is a fragmental end view of a ladle dumping car embodying the present improvements. Fig. 2is a vertical section taken approximately on the line 22 of F ig. 1. Fig. 3 is a sectional view of the line of Fig. 2. F ig. l is a detail view taken on the line i -4 of F ig. 2. Fig. 5 is a sectional view taken on the line 55 of Fig. 2. Fig. 6, is a sectional detail of the controlling valve. Fig. 7 is a plan view of the controlllng valve. Fig. 8 is a detail view in plan of the means for attaching the extension and piston rod. Fig. 9 is a detail view illustratmg a fragmental portion of the slide and latches for holding the same.
Inasmuch as the present improvements are employed on. the common ladle dumping car, as disclosed in the said patent, supra, it is not deemed necessary to illustrate or describe the general or complete construction of the car, since reference may be had to the said patent, and ladle dumping cars have become so well known in practice, that the application of the improved features thereto will be readily understood by those skilled in the art, it is thought.
The fragmental portion of the ladle dumping car depicted in the drawing. illustrates a portion of the frame 1 of the car,
and a portion of the ring or carrier 2 in which the ladle (not shown) is seated. This ring or'carrier 2 has trunnions rolling upon the frame 1, only one of the trunnions, designated 3, being illustrated. This trunnion 3 is the one that is actuated for moving the ring or carrier 2, and rolls upon a horizontal support or rail 1 of the frame 1, and which is provided with a rack 5. The trunnion 3 is provided with a gear se'g'mentti engaging the rack 5, whereby the trunnion 3 is constrained to roll properly upon the transverse support or rail 4'. The actuating mechanism for tilting the ring or carrier 2 includes a pair of standards 7projecting upwardly from the frame 1 at the opposite ends of the support or rail 4, and a pair of vertically spaced transverse guide rods 8 terminally attached to the standards 7; and having the cross head 9 mounted for sliding movement thereon. The cross head-9 is pro vided with an extension 10projecti'ng toward one side, and having its end secured or pivoted to the outer end of the piston rod 11 which is attached at its other end to the piston 12 which reciprocates within the transverse cylinder 13 supported by the frame 1'.
The grooves 15 have the straight vertical.
upper portions 16, and the converging curved lower portions 17 have their lower ends open. When cross head 9' is reciprocated transversely along its guide, the pins 14 of the trunnion 3 being engaged to the grooves 15 of the cross head, will cause the ladle ring or carrier 2 to tilt properly toward one 'side or' the other, and when the cross head 9 is in neutral or intermediate position, the ring or carrier 2 will be held horizontal for holding the ladle up right. Referring to Fig. 3, supposing the cross head 9 is moved to the left, the right hand pin 14: willbe engaged by the right hand wall of the respective groove 15, and
the right hand pin 14 being moved to the left with the cross head 9 will roll the trunnions of the ring or carrier 2 to the left, and the ring or carrier will thus be properly tilted to the left, the left hand pin 14: swinging downwardly along the curved portion 17 of the respective groove. Then the right hand pin 14E reaches the upper end of its groove 15, the tilting movement of the ladle ring or carrier will be stopped. The converse is true when the cross head is moved in the opposite direction. The interengaging portions of the trunnion 3 and cross head 9 will serve to effectively move the ladle ring or carrier when the cross head is reciprocated, and the ladle ring or carrier will be held steady at any position thereof.
The end portions of the cylinder 13 are connected by means of the respective pipes 18 and 19 to a controlling valve 20 to which the pressure fluid supply pipe 21 is connected. This pipe 21 has a controlling valve 22 for establishing and cutting off the flow of pressure fluid to the cylinder 13. The valve 20 is operable in the ordinary manner, to allow the pressure fluid to flow into the cylinder 13 through one of the pipes 18-19 and to flow out of the other end of the cylinder through the other of the said pipes, when the valve 20 is set at one position, and to allow the pressure fluid to flow into and out of the opposite ends of the cylinder when the valve 20 is reversed. Since the valve 20 is of ordinary construction, it is not necessary to illustrate or describe the same in detail.
The locking mechanism cooperates with a depending stop flange 23 carried by the cross head 9, and embodies a pair of latch devices. These latch devices embody rock shafts 24 and 25 journaled in suitable bearings 26 carried by the frame 1, and having secured thereon the respective latches 27 and 28. The rock shafts 2 1 and 25 are pro vided at their remote ends with handles 29 and 30, respectively, and the latches 27 and 28 are provided with arms or portions 31 adapted to swing against or over the ends of the flange 23 of the cross head. The latches 27 and 28 are provided with opp0- sitely projecting arms 32 having curved ends 32 A mechanism is employed for holding one or both of the latches 2728 in engagement with the stop flange 23 of the cross head, and to this end, a transverse reciprocatory rod 33 is slidable through suitable bearings 3 1 bearings 34 for limiting the reciprocatory movement of the rod 33 properly. The respective parts are so arranged that when the rod 33 is moved to the left to the dotted line position, as seen in Fig. 5, the left hand detent 35 will be disengaged from the left hand latch 27, while the right hand detent 35 will still be engaged to the ri ht hand latch 28, for allowing the left han latch 27 to be released from the cross head, while the right handlatch 28 is held in active posi-; tion. Conversely, when the rod 33 is moved to the right, to the dotted line position illus-- trated in Fig. 1, the right hand detent 35 is disengaged from the right hand latch 28, while the left hand detent 35 is still in engagement with the left hand latch 27 to hold the left hand latch in action position. When the rod 33 is at a neutral or interme diate position, both of the detents 35 will be engaged to the latches for holding the shaft 37 carried by the frame in any suitable 1 manner, and having an angularly extending arm 38 adjacent its lower end working in the slotted portion 39 of the rod 33. The valve 20 embodies a casing 40, as seen in Fig. 6, to which the pipes 18, 19 and 21 are com nected, and a valve member 41 is rotatable within the casing 40 and has a pair of passages 4243. The casing 40 has a port 44: leading to the atmosphere, and the valve member 41 has a slotted arm 45 in which a second arm 4L6 of the shaft 37 works. parts are so arranged, that when the rod 33 is moved to the left, as viewed in Fig. 1, the arm 38 is swung to the left, and the arm 16 being swung similarly, will swing the arm 45 to the position illustrated in Fig. 6. This The 1 will cause the passage 42 of the valve member 41 to connect the pipes 18-21, while the passage -13 connects the pipe 19 with the port 14. The pressure fluid, will therefore flow from the pipe 21 through the pipe 18 into one end of the cylinder, while the pressure fluid will flow from the other end of the cylinder through the pipe 19 to the atmosphere. Vlhen the rod 33 is moved to the right, as viewed in Fig. 1, the shaft will be rotated in the opposite direction, so that the arm 4:6 swings to the right, to correspondingly swing the valve member 41. The passage .12 will now connect the pipes 19 and 21, and the passage will connect the pipe 18 with the port 1-1, so that the piston is operated in the opposite direction, as will be apparent.
In operation, when the ladle ring or carrier 2 is in neutral or normal horizontal position, the piston 12 will be disposed inten mediate the ends of the cylinder 1.3, and the cross head 9 will stand between the ends of 'ts guide. The flange 23 of the cross head will then lie between the latches 2-7 and 28, and the handles 29 and 30 of the latches may be swung to swing the arms 31 of the latches across the ends of the flange 23. lhe rod 33 is then moved to neutral or intermediateposition so that the detents 35 thereof will hold the latches 27 and 28 in operative position, and the flange 23 of the cross head lying between the latches, will prevent the cross head from reciprocating or sliding. This will lock the ladle ring or carrier in neutral or normal position, so that there will be no liability whatever :tor the ladle to be dumped or discharged accidentally.
New, sup iosing it is desired to dump the ladle to the right, as seen in Fig. 1, the rod 93 is moved to the right as to release the right hand latch 28, and the right hand latch 28 may then be swung out of engagement vith the flange The right hand latch 28 is thus swung out of the path. of the flange 23, and the valve 20 is set so that the pressure fluid can flow from the supply pipe 2-1 through the pipe 18 into the left hand end of the cylinder 13. Consequently, when. the valve 22 is opened, the piston 12 will be moved to the right, the pressure fluid being discharged from the right hand end of the cylinder 13 through the pipe 19, and the cross head 9 will be moved to the right. so as to dump the ladle correspondingly. The left hand latch 27, in the meantime, is still locked in active position, and when the ladle is emptied and returned to normal position, the flange 23 of the cross head will strike against the latch 27 to limit the movement of he cross head when it reaches its normal or neutral position. The latch 28 may then he swung to active position. for holding the cross head in place, and the rod 83 is then moved to normal or neutral position for holding the. latch 28 as well as the latch 27 in active position.
Supposing that it is desired to dump the air to the left, as seen in Fig. 1, the rod 33 is moved to the left, so as to release the left hand latch 27, and to so set the valve 20 as to bring the supply pipe 21 into communication with the pipe 19, and to open the pipe 18 to the atmosphere. The latch 27 is then swung out of engagement from the flange 23, and the ralv is then opened so as to force the piston 12 to the left, for dumping' the ladle to the left side. lVhen the ladle is emptied and returned to normal position, the cross head 9 will be moved back against the right hand latch 28, and the left hand latch may then be swung to active position to hold the cross head in place, and after which the rod 33 may be moved to neutral position for locking both of the latches in active position.
The atches 27 and 2S swing counter clockse, as seen in Fig. 52, when they are dis en; .ged from the cross head, and since the detents normally engage the ends 3; of the arms of the latches, the detents will prevent the latches from swinging to re leased positions.
From the ifor-egoin taken in connection with the drawings, it is believed that the advantages and attributes of the invention will be apparent without further comment being necessary.
